DETAILED DESCRIPTION OF THE INVENTION
[0197] The term patient or subject is used throughout the specification within context to describe an animal, generally a mammal and preferably a human, to whom treatment, including prophylactic treatment, with the compositions and/or methods according to the present invention is provided. For treatment of a particular condition or disease state which is specific for a specific animal such as a human patient, the term patient refers to that specific animal. Preferred subjects include humans and domesticated animals, including dogs, cats, horses, cows, pigs, among others.
[0198] The term effective is used herein, unless otherwise indicated, to describe an amount of a compound, composition or component and for an appropriate period of time which, in context, is used to produce or effect an intended result, whether that result relates to the treatment of a disorder or condition associated with the present invention or alternatively, is used to produce another composure, agent or composition. This term subsumes all other effective amount or effective concentration terms which are otherwise described in the present application. In many instances, with the administration of D-glucose (dextrose) as a ileal brake hormone releasing substance in compositions and methods according to the present invention, an effective amount of D-glucose ranges from about 500 mg. to about 12.5 grams or more up to about 20 grams, preferably at least about 5 grams to about 10 grams up to about 20 grams used on a daily basis.
[0199] The term nutritional substance is used synonymously with pharmaceutical composition and ileal brake hormone releasing substance in certain contexts herein and refers to the substance which produces the intended effect in the ileum of a patient or subject pursuant to the present invention. A nutritional substance includes, but is not limited to, proteins and associated amino acids, fats including saturated fats, monosaturated fats, polyunsaturated fats, essential fatty acids, Omega-3 and Omega-6 fatty acids, trans fatty acids, cholesterol, fat substitutes, carbohydrates such as dietary fiber (both soluble and insoluble fiber), starch, sugars (including monosaccharides, fructose, galactose, glucose, disaccharides, lactose, maltose, sucrose, and alcohol), polymeric glucoses including inulin and polydextrose, natural sugar substitutes (including brazzein, Curculin, erythritol, fructose, glycyrrhizin, glycyrrhizin, glycerol, hydrogenated starch hydrosylates, isomalt, lactitol, mabinlin, maltitol, mannitol, miraculin, monellin, pentadin, sorbitol, stevia, tagatose, thaumatin, and xylitol), sahlep, berberine in its available forms and halwa root extract D-glucose (dextrose) is a preferred ileal brake hormone releasing substance. Ileal brake hormone releasing substances include all compositions that yield the aforementioned nutrients upon digestion or that contain such nutrients, including polymeric forms of these nutrients.
[0200] Additional ileal brake hormone releasing components which may be included in compositions according to the present invention include, barley grass, known to be a rich source of highly metabolizable vitamins and minerals such as vitamins A, BI, B2, B6, B12 and C, potassium, magnesium, and zinc. In addition, barley grass also has a high concentration of the enzyme superoxide dismutase (SOD), which has been shown to have high levels of antioxidant activity. Barley grass is believed to be an important nutrient in the regulation of the digestive process because the micronutrients, enzymes (e.g., SOD), and fiber contained in barley grass are believed to improve intestinal function.
[0201] Alfalfa fresh or dried leaf tea is also usable in the invention, to promote appetite, and as a good source of chlorophyll and fiber. Alfalfa contains biotin, calcium, choline, inositol, iron, magnesium, PABA, phosphorus, potassium, protein, sodium, sulfur, tryptophan (amino acid), and vitamins A, B complex, C, D, E, K, P, and U. Alfalfa supplements are recommended for treating poor digestion, and were shown to lower cholesterol levels in animal studies. Alfalfa is categorized as Generally Regarded as Safe (GRAS) by the FDA. Dosages can range from 25-1500 mg, preferably 500-1000 mg dried leaf per day.
[0202] Chlorella is yet another substance usable in the invention in combination with the ileal brake hormone releasing substance (preferably D-glucose or dextrose), being a genus of unicellular green algae, grown and harvested in tanks, purified, processed and dried to form a powder. Chlorella is rich in chlorophyll, carotenes, and contains the full vitamin B complex, vitamins E and C, and has a wide range of minerals, including magnesium, potassium, iron and calcium. Chlorella also provides dietary fiber, nucleic acids, amino acids, enzymes, CGF (Chlorella Growth Factor) and other substances. Dosages can range from 300-1500 mg/day.
[0203] Chlorophyllin is yet another ileal brake hormone releasing substance, being a known food additive and has been used as an alternative medicine. Chlorophyllin is a water-soluble, semi-synthetic sodium/copper derivative of chlorophyll, and the active ingredient in a number of internally-taken preparations intended to reduce odors associated with incontinence, colostomies and similar procedures, as well as body odor in general. It is also available as a topical preparation, purportedly useful for treatment and odor control of wounds, injuries, and other skin conditions, such as for radiation burns.
[0204] Sodium alginate may also be used as a nutritional substance, preferably in combination with D-glucose or dextrose.
[0205] The term ileum is used to describe the third (of three) portion of the small intestine just before the small intestine becomes the large intestine in the gastrointestinal tract. The ileum is the :final section of the small intestine in higher vertebrates, including mammals.
[0206] The ileum follows the duodenum and jejunum in the small intestine, and is separated from the Cecum or Colon by the ileocecal valve (ICV). In humans, the ileum is about 2-4 meters long, and the pH usually ranges between about 7 and 8 (neutral or slightly alkaline). The function of the ileum is mainly sensory and regulatory, and in that regard facilitates detection of malabsorption upstream. Additional functions of the ileum, include the absorption of certain vitamins, bile salts and whatever products of digestion were not absorbed by the jejunum. The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. In turn, the epithelial cells which line these villi possess even larger numbers of microvilli. Therefore, the ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion. The DNES (diffuse neuroendocrine system) cells that line the ileum contain lesser amounts of the protease and carbohydrase enzymes (gastrin, secretin, and cholecystokinin) responsible for the final stages of protein and carbohydrate digestion. These enzymes are present in the cytoplasm of the epithelial cells.
[0207] The term delays the release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the subject's ileum means: (1) that not less than around 50% by weight, not less than around 70% by weight, more preferably not less than around 80% by weight, and more preferably not less than around 90% and in certain instances substantially all of the ileal brake hormone releasing substance remains unreleased in vivo prior to the dosage form's arrival at a subject's ileum; and (2) that not less than around 50%, not less than around 70% by weight, more preferably not less than around 80% by weight, and more preferably not less than around 90%, of the ileal brake hormone releasing substance is remains unreleased in vivo by the time when the dosage form enters the subject's ileum. In preferred aspects of the invention this amount is at least about 1 gram, at least about 2.5 grams, at least about 3 grams, often at least about 5 grams, at least about 7.5 grams, preferably about 10 grams to about 12-12.5 grams or more (about 12.5 to about 20 grams, especially of polymeric materials such as polydextrose or those compounds of higher molecular weight) of the ileal brake hormone releasing substance and in particular, glucose, is released within the small intestine in the ileum in order to stimulate ileum hormones and related hormones and effect the intended result associated with lowering the manifestations of metabolic syndrome and/or influencing one or more of insulin resistance (decrease resistance), blood glucose (decrease in/stabilize glucose levels), glucagon secretion (decrease), insulin release (decrease and/or stabilize release and/or levels), ileum hormone release (increase) or other hormone release, in particular, one or more of GLP-1, glicentin, C-terminally glycine-extended GLP-1 (7 37), (PG (78 108)); C-peptide, intervening pepT1De-2 (PG (111 122) amide); GLP-2 (PG (126 158), GRPP (PG (1 30)), oxyntomodulin (PG (33 69), and other peptide fractions to be isolated, PYY (1-36), PYY (3-36), enteroglucagon, neurotensin, as well as leptin, IGF-1 and IGF-2, and preferably, one or more, two or more, three or more, four or more, five or more, six or more, seven or more, or all of GLP-1, GLP-2, C-pepT1De, PYY (1-36 and/or 3-36), glucagon, leptin, IGF-1 and IGF-2.
[0208] The term ileum hormones includes all hormones that are associated with intraluminal food substances stimulating the release of said hormones, could be associated with action of the ileal brake and associated feedback from the ileum or ileum-related stimulation of insulin secretion or inhibition of glucagon secretion. Ileum hormones therefore include, but are not limited to, GLP-1, glicentin, C-terminally glycine-extended GLP-1 (7 37), (PG (78 108)); intervening peptide-2 (PG (111 122) amide); GLP-2 (PG (126-158), GRPP (PG (1 30)), oxyntomodulin (PG (33 69), and other peptide fractions to be isolated, PYY (PYY 1-36) and (PYY 3-36), enteroglucagon and neurotensin.
[0209] The term ileum hormone-stimulating amount of a nutritional substance means any amount of a nutritional substance that is effective to induce measurable hormone release in the ileum, and induce feedback from the ileum or ileum-related stimulation of insulin secretion or inhibition of glucagon secretion, or other effect such as shutting down or decreasing insulin resistance and increasing glucose tolerance. Consequently, an ileum hormone-stimulating amount of a nutritional substance can vary widely in dosage depending upon factors such as the specific nutrient at issue the desired effect of administration, the desired goal of minimizing caloric intake, and the characteristics of the subject to whom the ileal brake hormone releasing substance is administered. For example, at least about 500 mg of D-glucose is used, and a particularly preferred ileum hormonal-stimulating amount of D-glucose includes between about 5 to 20 grams, often about 7.5-8 g to about 12-12.5 g (preferably around 10 g).
[0210] The following terms and/or concepts also help define the present invention.
[0211] SD Ratio Derivation, CV Risk Definition in T2D:
[0212] SD (Supply/Demand) index was developed by the inventors to quantify the impact of dietary glucose load on T2D, and to develop a means of rank ordering the impact of effective treatments that change T2D responsiveness by interrupting glucose supply. (see Monte U.S. Pat. No. 8,367,418, incorporated by reference in its entirety herein). By identifying quantitative differences between anT1Diabetic agents on carbohydrate exposure (CE), hepatic glucose uptake (HGU), hepatic gluconeogenesis (GNG), insulin resistance (IR), peripheral glucose uptake (PGU), and peripheral insulin exposure (PIE), the inventors created a pharmacokinetic/pharmacodynamic model to characterize the effect of the agents on the glucose supply and insulin demand dynamic. Glucose supply was defined as the cumulative percentage decrease in CE, increase in HGU, decrease in GNG, and decrease in IR, while insulin demand was defined as the cumulative percentage increase in PIE and PGU (See figure J 5 for the recitation of SD ratio). According to the teachings of Supply Side and by reference to treatments with a high SD ratio number (a value above 2.0), the inventors show that a drug used for T2D has beneficial interaction with a lowering of glucose supply, considered now an essential component to lowering of insulin resistance and insulin demand from immediate release glucose load (see
[0213] Because T2D cardiovascular outcome trials have not demonstrated macrovascular benefit with more aggressive blood glucose reduction when using conventional algorithms that predominantly focus on insulin demand, it would appear logical to consider a model that incorporates both the extent of blood glucose lowering as HBA1c and the means by which the blood glucose was reduced (SD ratio) when considering macrovascular outcomes.
[0214] It was our objective to test the hypothesis that, in conjunction with HBA1c, patients managed on the glucose supply side of the model would have fewer CV events versus those managed on the insulin demand side. In a study of matched cases, we found that patients managed at higher glucose values and on the insulin demand side of the model have increased cardiovascular risk(2).
[0215] Glucose, Hunger and Metabolic Syndrome:
[0216] Continued hunger is the driver of glucose supply side driven metabolic syndrome, and there are accelerating hunger signals emitted from the L-cells of the ileum in absence of sufficient supply of distally available carbohydrate to satisfy the needs of the bacterial flora in the ileum, and in fact the L-cells themselves (see
[0217] Ileal brake associated hormone outputs not only produce satiety over the longer term but also begin to rapidly (i.e., within a day to several days) trigger the endogenous repair of pancreas, liver and GI tract cells. Together, these are the stop and repair processes that are programmed into our bodies to optimize the balance between ingestion and nutritional needs. As these systems are mainly programmed to satisfy basic needs for nutrition, they are most efficient in a relative lack of glucose as nutrition. Our current excessive nutrient ingestion patterns, especially a growing preference for rapidly absorbed immediate release and duodenally absorbed sugars that deny nutrition to distal intestinal bacteria, create overdrive of the hunger pathways directly to organ exhaustion and obesity without the benefit of the triggered repair. A simple fix for over-nutrition with rapidly absorbed sugars is to perform RYGB surgery (see
[0218] The present invention provides pharmaceutical compositions and methods of regenerating organs and tissues in a patient afflicted with one or more organ or tissue manifestations of glucose supply side associated metabolic syndrome, when the syndrome is accompanied by suppressed regenerating processes and progressively failing organs. A pharmaceutical composition in an effective dosage is provided to said metabolic syndrome patient, which wakes up the dormant ileal brake sensor and initiates renewed hormonal signals to regenerate candidate organs and tissues including but not limited to the pancreas, the liver, the enterocytes of the GI tract and the associated signal transmitting neurons, as well as the cardiovascular system, the lungs, the kidneys and brain (in some cases resolving or limiting the debilitation of Alzheimer's disease and other neurodegenerative disease states and/or enhancing cognition). These actions are assured by measured biomarkers of both the ileal hormone process and the resolution of metabolic syndrome and organ repair.
[0219] A pharmaceutical composition in a. li effective dosage is disclosed herein. When provided to said metabolic syndrome patient, the beneficial effect is activation of the dormant ileal brake Metasensor (see
[0220] Serially measured biomarkers of metabolic syndrome progression or regression, in this case the components of the FS index in patients given the compositions according to the present invention (Brake) or taken to RYGB surgery, demonstrate the successful regeneration. Once regeneration is accomplished by Brake or RYGB surgery, the regenerated organs then signal the patient, to resume adequate nutrition seeking behavior as directed by restored signals of hunger. Specific actions on organ regeneration are confirmed by measured biomarkers and analysis of the results (including a lowered value for the FS index, as disclosed fully below). Dependent on reserve capabilities of the patient at hand, and depending on composition and administered dosage of the pharmaceutical composition, the preset invention relates to dramatic improvement or potential cure of metabolic syndrome manifestations including but not limited to T2D, hyperlipidemia, atherosclerosis, insulin resistance, hypertension, and ASCVD.
[0221] Specific actions on organ regeneration are confirmed at each stage of treatment by measured biomarkers and FS index calculation, and analysis of the results and use of the index to adjust dosage and duration of treatment with the pharmaceutical composition. Dependent on reserve capabilities of the patient at hand, and depending on composition and administered dosage of the pharmaceutical composition, the present invention relates to dramatic improvement or potential cure of metabolic syndrome manifestations including but not limited to T2D, hyperlipidemia, atherosclerosis, insulin resistance, hypertension, and hepatic steatosis, as well as reversing organ damage for pancreas, liver, kidneys, heart and cardiovascular system (atherosclerosis and related manifestations of heart disease), GI tract and brain (including reversing, resolving and inhibiting Alzheimer's and other cognitive disorders by improving brain function. The FS index demonstrates these effects of said composition to the treating physician and thereby provides a roadmap to the regeneration of organs and tissues and associated lowering of cardiovascular risk.
[0222] The SD model certainly represents a new perspective on T2D causes and treatments. As the problem of glucose driven cardiovascular injury was further examined, it became clear to the inventors that a perspective broader than T2D alone needed to be considered as treatments were discovered based on RYGB mechanisms. This is the basis of the creation of the FS index, which is used to indicate damage to organs as a consequence of Metabolic Syndrome and other disease manifestations and also to indicate the extent of organ regeneration.
[0223] Metabolic Syndrome, Beyond T2D with FS Index
[0224] Compositions disclosed herein are effective for the treatment of Metabolic Syndrome inpatients. There are 5 key components defining Metabolic Syndrome: Abdominal adiposity (Male>40in waist, Female>35 inch waist), Elevated Triglycerides (>150), Low HDL Cholesterol(<40 male, <50 female), High blood pressure(>135/85), and Hyperglycemia (FBS>120 or HBA1c>7) (4-17) Note that the consensus definition of metabolic syndrome contains hyperglycemia, which is covered by the SD ratio. The other elements of metabolic syndrome were not covered until the inventors developed the FS index. There are several other variants within the consensus definitions as might be anticipated by a research community that does not consider this all to have a common cause or a common treatment methodology.
[0225] In the art of medicine, treating physicians consider each of the various aspects of metabolic syndrome to be a single disease, and they use a single Jab test to diagnose or monitor treatment progress. An example would be the use of BMI to diagnose or monitor weight gain, HBA1c or glucose to monitor diabetes, or cholesterol to diagnose or monitor hyperlipidemia. None of these approaches consider direct effects of pharmaceutical treatments, which themselves change the organ damage risk within each disease, as well as overall.
[0226] The FS index (Fayad/Schentag) of MS (the relevant equation for which appears in attached
[0227] The FS index of metabolic Syndrome provides or describes a predictive measurement of damage to a patient's organs pursuant to metabolic syndrome and/or related conditions of a patient and the necessity of administering the therapy of the present invention in order to regenerate those organs which have been damaged pursuant to the present invention. FS index was therefore invented to quantify the Metabolic Syndrome and the degree of organ and/or tissue damage to patients. As discovered, patients with Metabolic Syndrome have many different manifestations, while each individual may have an index made up of varying severity of T2D, hyperlipidemia, hypertension or NAFLD. Before FS index was invented, there was no means of tracking progression of metabolic syndrome in patient populations that may have any or all of these conditions to varying degree.
[0228] The goal of the inventors of FS index was to provide a means of identifying the likelihood that a patient will manifest organ and/or tissue damage from metabolic syndrome. Once risk can be quantified from each component of metabolic syndrome, compositions and effective treatments can be disclosed to mitigate the risk, and thereby show benefit when administered to patients. Thus, the FS index can be used to score metabolic syndrome manifestations in a patient such that the FS index is predictive of organ damage and corrective therapeutic steps may be taken to repair/regenerate those damaged organs using methods and compositions according to the present invention.
[0229] FS Index Methods
[0242] The FS index was then applied to well-studied patient populations already in databases, using a neural net model and the equation set forth in
[0243] Hepatitis C, NAFLD, or prediabetes. For each study patient, we had complete access to all raw data, measured vital signs, culture results, and clinician assessments. Many of these measures were incorporated as inputs into the neural net models, and are also illustrated on the Y ax.is as standard deviations above the defined normal mean of the parameter. The primary aim of the neural net modeling effort was to model CV events and CV mortality in relation to time course of Input parameters, with a second primary effort to model time course of organ failure as a metric in relation to Input factors such as those in the laboratory biomarkers listed above.
[0244] FS index values were calculated from serial laboratory and clinical data over timeframes ranging between 2 and 10 years. In these patient populations, a normal FS index value was 20-50. Patients with two or more manifestations of MS and increased organic damage risk profiles have FS index values above about 60, often above about 100, and quite often above 200. Maximum FS index values are above 500, typical when nearly every MS component is highly abnormal.
[0245] It was notable that many of the highest FS index patients the inventors observed are from morbidly obese patients who subsequently undergo RYGB surgery. Surprisingly, the surgical procedure cures every aspect of their metabolic syndrome. This discovery and studies of the mechanism of this cure via ileal brake hormone release and associated organ regeneration, directly led the inventors to the instant invention Brake, the first oral mimetic of RYGB to cure metabolic syndrome.
[0246] Using the Neural Net model in MatLab, the initial association of biomarker-mortality response surface was confirmed and extended by performing subset analyses to identify the most informative input biomarkers. Throughout this description of methods developed and applied, raw data from each patient are displayed vs. time via hyperlinks, and cumulative graphics are displayed. Unless otherwise stated, standard deviations (z-score) vs. time are presented in the individual and mean population graphics (
[0247] Except where specifically noted, standard deviations for each parameter are displayed on the Y axis, as this factor normalizes the different range of parameters for visual illustration of behavior pattern S in groups on a common Y axis. Unless otherwise noted, the X-axis displays time throughout this report.
[0248] For purposes of analysis, clinical and laboratory parameters were converted into modified z-scores as follows:
[0249] A mean normal value (described as mean in the following) was selected based on review of literature and various published laboratory compendia. The Standard Deviation (SD) of each parameter was set to one half of the normal range. The modified z-score is calculated as follows:
z=(Patient valuemean)/SD
[0250] On the graphs, the z-score is reported as the number of SD.
[0251] Outputs of the many runs of the database thru the Neural Net models can be presented both in graphical format and tables. In general, we use graphical displays for individual patients and groups of similar patients, and we use tables to present the results of runs of aggregate analyses performed on the individual patients. The general theme of presenting some highlights of the results is outlined as follows: [0252] Input/output relationships for Groups of patients [0253] Subsets of metabolic syndrome patients with common characteristics [0254] Individual patients with top 10 informative parameters displayed over time (examples in
[0255] In each Input/output graphic, the x axis is time and the y axis is multiples of SD over the normal value which is set at zero. This allows all parameters approximately equal weight in the display, recognizing that parameters behaving in a non-linear fashion will always appear more important in terms of large changes and that display bias cannot be completely removed from the display.
[0256] Ranked correlation lists for: [0257] Metabolic syndrome components and related events CV events [0258] Pharmacoeconomic Analyses [0259] Drug impacts on metabolic syndrome endpoints
[0260] Tables of rank ordered correlation parameters provided herein are all based on the somewhat time independent link between Inputs (usually the baseline parameter value at time of metabolic syndrome diagnosis) and Outputs calculated as cumulative or AUC variables; the multiples here stated are used to rank order the input in connection to the magnitude of the output, connecting inputs and outputs regardless of timing. Output Error is the Root Mean Squared (RMS) error between the enrichment model based on the input parameter (in this case the baseline biomarker) and the desired output of (for example, cumulative CV risk score), based on each input parameter for all the patients. A lower output error means that the parameter on its own is a better predictor, and the model seeks to find the best single parameter in all cases of RMS rank ordering.
[0261] These displays generally use the top two parameters for a ranked correlation and display them in 3D against a Z axis parameter of defined importance, such as cumulative CV, other organ damaging events, such as cumulative organ failures, etc. In some settings we use a parameter of interest even if it does not achieve top 2 status in ranked correlation, simply because it allows the study of the parameter more specifically across the entire population
[0262] These two dimensional graphical displays order the x-axis to start with the patient of lowest risk at zero, and the patient of highest risk at the last value. The y-axis is the risk score itself. Then we use color to define which patients have the event in question. For example, one can show increasing risk for CV events on these graphs, and the mark the patients with the actual events vs. their risk in an easy to identify display. Calculations of risk over zero (point separating half above and half below) allows an overall estimate of increasing or decreasing probability that roughly follows the more widely applied odds ratio. The advantage of doing the analysis with a neural net is that non-linear behavior is not excessively weighted over linear behavior
[0263] Final tables aggregating patterns of population behavior are derived from analysis of each individual, once again rank ordering inputs to outputs. In this run of the neural net, the question asked is what are the top 2-4 inputs for their particular behavior pattern. The tabulation of these data are used to define subsets that might be a focus for enrichment studies
[0264] FS Index Study Results
[0265] By way of summary, high FS index values generally precede and therefore predict organ damage events in metabolic syndrome patients, regardless of the specific components of Metabolic Syndrome that were abnormal. Abnormal and rising FS index values predict organ damage, although it does not predict the time of the event. A rapid rise in the FS index over 3-6 months is a good predictor of impending organ damage events. When Metabolic Syndrome is studied as the equal weight of its components using the FS index, it is apparent why clinical strategies treating only one component of Metabolic Syndrome do not predict or remove all risk of organ damage events.
[0266] Abnormal FS index values, when subsequently normalized, indicate resolution of each component of Metabolic Syndrome, raising the possibility that specific treatments of
[0267] Metabolic Syndrome might halt progression or reverse Metabolic Syndrome and resulting organ damage entirely. A cure is often effected.
[0268] High FS index values (at least about 60, often 100, or 200, at least about 300, at least about 400, at least about 500 or more) predicts organ damage and a necessity to regenerate organs in such patients, regardless of the specific components of metabolic syndrome that were abnormal. Abnormal and rising FS index values predicted a greater likelihood of organ damage and identify a more urgent need for organ regeneration. When MS is studied as the equal weight of its components using the FS index, it is apparent why drug treatments effective for only one component of MS do not remove all risk of subsequent CV events. The index also explains why drug therapies that improve one aspect of MS but worsen others may not mitigate organ damage or provide organ regeneration.
[0269] An example might be Metformin when used alone (see
[0270] Abnormal FS index values which are subsequently normalized through administration of a composition according to the present invention (i.e. Brake), indicated resolution of each component of MS syndrome, raising the possibility that specific treatments of MS might halt progression or reverse MS entirely, all the while working synergistically with the usual drugs applied and considered effective for each separate component of the metabolic syndrome. For example, changes in FS index in patients with RYGB surgery (
[0271] The index also at least partially explains why drug therapies that improve one aspect of Metabolic Syndrome, but worsen others, appear not to mitigate organ damage risk or remove organ damaging events in complex Metabolic Syndrome patients. The index does also show that combination therapies consisting of individual drugs, each used for one component of metabolic syndrome may lower FS index by altering each component. One advantage of using the FS index is its perspective on the importance of combination therapy and in these specific examples to follow the FS index shows the importance of certain combination therapy beneficial on the glucose supply side, such as the composition therapy according to the present invention (Brake therapy).
[0272] Metabolic Syndrome-a Composite Condition Vs. A Series of Loosely Related Parts
[0273] There are many isolated laboratory predictors for the presence of individual diseases such as T2D predicted by HBA 1c or fasting blood glucose. Such parameters predict the disease and can be used to monitor the control of the parameter, such as when insulin lowers the blood glucose. Laboratory predictors of diseases are designed to be applied to disease detection over very broad populations of heterogeneous patients. These patients may have complex mixtures of diseases and treatments, and thus a broadly applicable but single parameter index such as high LDL cholesterol might separate some of the more obvious high risk atherosclerosis patients who have underlying lipid abnormalities, but not perform well on individuals who might deviate from the core metabolic syndrome model used to derive the index. There is currently no global index which predicts the risk of metabolic syndrome organ damage, and in fact other than the inventors, the idea that all of these diseases are phenotypic manifestations of an underlying metabolic syndrome pattern is not found in the literature. Since many of these patients have more than one metabolic syndrome parameter abnormal, we have since then expanded the concept of SD into patients who have other metabolic syndrome associated diseases concomitant with diabetes, such as Congestive
[0274] Heart Failure, fatty Liver disease, Hepatitis C, COPD, Alzheimer's disease, sepsis and others.
[0275] Expanding the concept, the newly developed FS index (the method defining effective treatment with the disclosed pharmaceutical compositions in this application) handles all the common manifestations of Metabolic Syndrome, each of which was previously thought to be variably related to CV endpoints. So, the now highly novel FS index is designed to broadly model all the important aspects of metabolic syndrome (weight, triglycerides, liver inflammation, insulin production and SD ratio) and derive organ damage (generally) risk therefrom. Important to note that SD ratio is built into FS index as one of its 6 main components.
[0276] The term metabolic syndrome manifestation refers to a physiological effect, including a secondary effect which occurs in a subject who suffers from metabolic syndrome. Specific metabolic syndrome manifestations include but are not limited to T2D, hyperlipidemia, atherosclerosis, insulin resistance, hypertension, and Hepatic Steatosis. pancreas and/or pancreatic beta cell damage, hepatic steatosis, NAFLD, hyperlipidemia, elevated triglycerides, abdominal adiposity, atherosclerosis, cardiovascular diseases such as myocardial infarction, stroke, angina, congestive heart failure, hypertension, ASCVD,
[0277] reduced lung capacity (COPD), Rheumatoid arthritis, diabetic nephropathy leading to kidney failure, gastrointestinal tract damage, gastrointestinal dysbiosis, inflammatory bowel disease, brain damage, neurodegenerative disorders, diabetic neuropathy, cognitive impertinent associated with obesity and early Alzheimer's disease, among others as otherwise described herein.
[0278] The term gastrointestinal disorder includes diarrheal states, malabsorption in the upper gut (i.e., chronic pancreatitis, celiac disease), fatty liver, atrophic gastritis, short bowel syndrome, radiation enteritis, irritable bowel disease, Crohn's disease, post infectious syndrome, mild reflux, certain gut dysmotility, post chemotherapy disorder, malnutrition, malabsorption, and voluntary or involuntary long term starvation. The present invention may be used to treat each of these conditions, alone or secondary to the treatment or resolution of symptoms associated with T2D, pre-diabetic symptoms, metabolic syndrome and insulin resistance. To the extent that patients with Type 1 diabetes (T1D) manifest these metabolic syndrome properties, the present invention may also beneficially impact their outcome and slow progression of cardiovascular injury.
[0279] Formulations, Dosage Forms and Combinations
[0280] In particular, the present invention generally proceeds when the steps in practice of the invention include the testing of the patient for laboratory biomarker patterns, use of the results of testing to calculate the FS index, determining the risk of organ damaging events from the FS index calculation (when the FS index measures at least about 60, 100, 150, 200, 300, 400 or 500 and above), then the application of personalized treatment to lower the FS index, most preferably by the administration of a pharmaceutical composition targeted to a specific receptor (on the L-cells) in the distal intestine, in a dosage and duration of treatment to lower the FS index of the patient upon repeat measurements.
[0281] The effect of the medicament on the measured biomarkers demonstrates beneficial properties of the ileal brake hormone releasing substance on the laboratory tests that comprise the FS index. In the ordinary assessment of the precise sequence of hormonally produced events, the patient experiences cessation of hunger. The patient benefits from the ileal brake hormone release with regeneration of organs and tissues, typically pancreas, liver and gastrointestinal tract.
[0282] With respect to the sequence of signaling molecules from the ileum, a response to the medicament entails a wake up stimulation of distal intestinal L-cells that have been quieted by actions of intestinal bacteria or metabolic disease; there is a release of hormones and signals from said L-cells; said released hormones traveling in portal blood to pancreas, liver and GI tract, said organs regenerated from available growth factors and hormone signals, measured biomarkers of the FS index demonstrating the successful regeneration and said regenerated organs then signaling the patient, preferably a human, to resume adequate nutrition seeking behavior as directed by restored signals of hunger.
[0283] Dosage forms used in methods of the invention can be in a form suitable for oral use, for example, as tablets, troches, lozenges, suspensions, micro suspensions, dispersible powders or granules, emulsions, micro emulsions, hard or soft capsules. Useful dosage forms include osmotic delivery systems as described in U.S. Pat. Nos. 4,256,108; 5,650,170 and 5,681,584, multiparticulate systems as disclosed in U.S. Pat. No. 4,193,985; systems in which the nutritional substance is coated with a mixed film of a hydrophobic organic compound-enteric polymer as disclosed in U.S. Pat. No. 6,638,534; systems such as those described in U.S. Pat. Nos. 7,081,239; 5,900,252; 5,603,953; and 5,573,779; enteric-coated dry emulsion formulations (e.g., Journal of Controlled Release, vol. 107, issue 120 September 2005, Pages 91-96), and emulsions such as the emulsion system of Olibra and those disclosed in U.S. Pat. No. 5,885,590. Those of ordinary skill in the prior art know how to formulate these various dosage forms such that they release the majority of their nutritional substance in a subject's ileum (preferably within a pH range of about 7.0 to about 8.0, often about 7.2 to about 7.5) as otherwise described herein.
[0284] Exemplary dosage forms that will release the majority of the ileal brake hormone releasing substance (i.e., at least about 50% of the substance administered) in vivo upon reaching the ileum include oral dosage forms such as tablets, troches, lozenges, dispersible powders or granules, or a hard or soft capsules which are formed by coating the ileal brake hormone releasing substance with an enteric coating (e.g., an enteric cellulose derivative, an enteric acrylic copolymer, an enteric maleic copolymer, an enteric polyvinyl derivative, or shellac). Preferred enteric coatings have a pH dissolution profile that delays the release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum. Enteric coatings can consist of a single composition, or can comprise two or more compositions, e.g., two or more polymers or hydrophobic organic compound-enteric polymer compositions as described in U.S. Pat. No. 6,638,534).
[0285] A material having a pH dissolution profile that delays release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum includes but is not limited to cellulose acetate trimellitiate (CAT), hydroxypropylmethyl cellulose phthalate (HPMCP), polyvinyl acetate phthalate (PVAP), cellulose acetate phthalate (CAP), shellac, copolymers of methacrylic acid and ethyl acrylate, copolymers of methacrylic acid and ethylacrylate to which a monomer of methylacrylate has been added during polymerization, a mixture of amylose-butan-1-ol complex (glassy amylose) with Ethocel aqueous dispersion (Milojevic et al., Proc. Int. Symp. Contr. Rel. Bioact. Mater. 20, 288, 1993), a coating formulation comprising an inner coating of glassy amylose and an outer coating of cellulose or acrylic polymer material (Allwood et al. GB 9025373.3), calcium pectinate (Rubenstein et al., Pharm. Res., 10, 258, 1993) pectin, chondroitin sulfate (Rubenstein et al. Pharm. Res. 9, 276, 1992), resistant starches (PCT WO 89/11269), dextran hydrogels (Hovgaard, et al., 3rd Eur. Symp. Control. Drug Del., Abstract Book, 1994, 87) modified guar gum such as borax modified guar gum, (Rubenstein and Gliko-Kabir, S. T. P. Pharma Sciences 5, 41-46, 1995), beta-cyclodextrin (Sidke et al., Eu. J. Pharm. Biopharm. 40 (suppl), 335, 1994), saccharide containing polymers, e.g., a polymeric construct comprising a synthetic oligosaccharide-containing biopolymer including methacrylic polymers covalently coupled to oligosaccharides such as cellobiose, lactulose, raffinose and stachyose, or saccharide-containing, natural polymers including modified mucopolysaccharides such as cross-linked pectate (Sintov and Rubenstein PCT/US 91/03014); methacrylate-galactomannan (Lehmann and Dreher, Proc. Int. Symp. Control. Rel. Bioact. Mater. 18, 331, 1991) and pH-sensitive hydrogels (Kopecek et al., J. Control. Rel. 19, 121, 1992), and resistant starches, e.g., glassy amylase, among others known in the art.
[0286] Methylmethacrylates or copolymers of methacrylic acid and methylmethacrylate are preferred materials having a pH dissolution profile that delays release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum. Such materials are available as Eudragit polymers (Rohm Pharma, Darmstadt, Germany). For example, Eudragit L100 and Eudragit S100 can be used, either alone or in combination. Eudragit L100 dissolves at pH 6 and upwards and comprises 48.3% methacrylic acid units per g dry substance; Eudragit 5100 dissolves at pH 7 and upwards and comprises 29.2% methacrylic acid units per g dry substance. Generally, the encapsulating polymer has a polymeric backbone and acid or other solubilizing functional groups. Polymers which have been found suitable for purposes of the present invention include polyacrylates, cyclic acrylate polymer, polyacrylic acids and polyacrylamides. Another preferred group of encapsulating polymers are the polyacrylic acids Eudragit L and Eudragit S which optionally may be combined with Eudragit RL or RS. These modified acrylic acids are useful since they can be made soluble at a pH of 6 or 7.5, depending on the particular Eudragit chosen, and on the proportion of Eudragit S to Eudragit L, RS, and RL used in the formulation. By combining one or both of Eudragit L and Eudragit S with Eudragit RL and RS (5-25%), it is possible to obtain a stronger capsule wall and still retain the capsule's pH-dependent solubility. In additional preferred aspects of the invention, a coating of shellac (which also includes one or more emulsifiers such as hypromellose and/or triacetin) which is chosen to have a suitable pH-dependent dissolution profile for release the contents of a dosage form such as a tablet within the ileum of a patient or subject may be used. This type of coating provides a nutrateric approach to delayed and/or controlled release using naturally occurring, non-synthetic components.
[0287] A delayed and/or controlled release oral dosage form used in the invention can comprise a core containing an ileum L-cell-stimulating amount of an ileal brake hormone releasing substance that is coated by an enteric coating. In some embodiments, the coating comprises Eudragit L100 and shellac, or food glaze Eudragit 5100 in the range of 100 parts L100:0 parts 5100 to 20 parts L100:80 parts 5100, more preferably 70 parts L100:30 parts 5100 to 80 parts L 100:20 parts 5100. As the pH at which the coating begins to dissolve increases, the thickness necessary to achieve ileum-specific delivery decreases. For formulations where the ratio of Eudragit L100:S100 is high, a coat thickness of the order 150-200 m can be used. For coatings where the ratio Eudragit L 100:S100 is low, a coat thickness of the order 80-120 m can be used. Dosage forms used in methods of the invention can include one or more pharmaceutically acceptable carriers, additives, or excipients. The term pharmaceutically acceptable refers to a carrier, additive or excipient which is not unacceptably toxic to the subject to which it is administered. Pharmaceutically acceptable excipients are described at length by E. W. Martin, in Remington's Pharmaceutical Sciences, among others well-known in the art. pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose, and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, cetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk glucoses, as well as high molecular weight polyethylene glycols and the like.
[0288] Generally, the membrane or sustained release coating around the core, when formed with shellac, will comprise from about 5% to about 10% and preferably about 6% to about 8% based upon the total weight of the core and coating.
[0289] Independent of the core ileal brake hormone releasing substance is a second active drug, in a preferred embodiment a metformin derivative (e.g. a biguanide).
[0290] Additional preferred embodiment second active drugs of the invention include 10 mg of atorvastatin (Lipitor) or any statin in an equivalent amount, chosen from the alternative listing: Fluvastatin (Lescol), Lovastatin (Mevacor), Pitavastatin (Livalo), Pravastatin (Pravachol), Rosuvastatin (Crestor), Simvastatin (Zocor), among other possible statins.
[0291] Angiotensin Converting Enzyme (ACE) inhibitors with preferred example a 10 mg daily dose of Lisinopril (Prinivil, Zestril) or a suitable alternative in an equivalent amount chosen from those marketed ACE inhibitors: benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), trandolapril (Mavik). among other possible alternative ACE inhibitors.
[0292] Angiotensin II inhibitors with preferred example an 80 mg dose of Losartan or an equivalent amount of alternative Angiotensin II inhibitor including but not limited to candesartan, irbesartan, valsartan, olmesartan, Telmisartan, among other possible Angiotensin II inhibitors.
[0293] Beta Blockers with preferred example propranolol (Inderal) in a dose of 20 mg or a suitable alternative in an equivalent amount chosen from the list of beta blockers: acebutolol (Sectral); atenolol (Tenonnin); betaxolol (Kerlone); bisoprolol (Zebeta); carteolol (Cartrol); esmolol (Brevibloc); metoprolol (Lopressor); penbutolol (Levatol); nadolol (Corgard); nebivolol (Bystolic); pindolol (Visken); timolol (Blocadren); sotalol (Betapace); carvedilol (Coreg); labetalol (Trandat), among other possible beta blockers.
[0294] Ribavirin or any antiviral agent; methotrexate or any anti-inflammatory agent; memantine or any anti-Alzheimer's agent; sitagliptin or any DPP-IV anti-hyperglycemic agent; phentermine or any anti-obesity agent; berberine; vitamin B12; omeprazole or any proton pump inhibitor; sildenafil or any PDE-5 inhibitor; olanzapine, risperidone or any of the major tranquilizers.
[0295] In preferred embodiments by way of example, for each of the second active drugs listed above, when applied as an over-coating, the daily dose will be apportioned over 7 tablets of core ileal brake hormone releasing substance, such that each controlled release tablet is over-coated with 1/7.sup.th of the total effective daily dose of second active agent. The range of effective daily doses for each of the over-coated second active drugs are as follows: atorvastatin (10 mg) or any statin (5-25 mg); lisinopril (10 mg) or any ACE inhibitor (5-100 mg); olmesartan (5-20 mg) or any Angiotensin II inhibitor (10-100 mg); propranolol (10-40 mg) or any beta blocker (5-100 mg); ribavirin (600-1200 mg) or any antiviral agent; methotrexate (1-5 mg) or any anti-inflammatory agent; memantine (5-20 mg) or any anti-Alzheimer's agent; sitagliptin (50-100 mg) or any DPP-IV anti-hyperglycemic agent(5-100 mg); phentermine (18-37 mg) or any anti-obesity agent; berberine (500-1500 mg) in its available forms; vitamin B12(5-25 mcg); omeprazole (10-20 mg) or any proton pump inhibitor (5-100 mg); sildenafil (10-50 mg) or any PDE-5 inhibitor (5-50 mg);olanzapine(5-20 mg), risperidone (1-5 mg) or any of the major tranquilizers.
[0296] The second active drug may be formulated often as an over-coating on the tablets of the ilea} brake hormone releasing substance, in order to provide an immediate or early release of the second drug. Optionally, the second drug layer may be over-coated with a seal coat after the layer is applied. In one embodiment of the present invention, the metformin derivative is applied in the form of a layer to a controlled release core comprising the ileal brake hormone releasing substance as a layer using a binder and other conventional pharmaceutical excipients such as absorption enhancers, surfactants, plasticizers, antifoaming agents and combinations of the foregoing. An absorption enhancer may be present in the metformin derivative layer in an amount up to about 30% w/w in comparison to the weight of the metformin derivative. A binding agent may be present in an amount up to about 150% w/w of the metformin derivative. A second active drug immediate release formulation may be incorporated into a single dosage form by coating onto the membrane or sustained release coating of the dosage form by conventional methods. The incorporation of the second active drug may be performed by, but would not be limited to, the processes selected from the group consisting of drug layering, lamination, dry compression, deposition, printing and the like.
[0297] When the metformin derivative is coated onto a membrane or controlled release coating of an osmotic tablet core, the metformin coating should be applied from a coating solution or suspension that employs an aqueous solvent, an organic solvent or a mixture of an aqueous and an organic solvent. Typical organic solvents include acetone, isopropyl alcohol, methanol and ethanol. If a mixture of aqueous and organic solvents is employed, the ratio of water to organic solvent should range from about 98:2 to 2:98, preferably about 50:50 to 2:98, most preferably about 30:70 to 20:80 and ideally about 25:75 to 20:80. If a mixed solvent system is employed, the amount of binder required for coating the metformin derivative onto the membrane or sustained release coating may be reduced. For example, successful coatings have been obtained from a mixed solvent system where the ratio of binder to metformin derivative is 1:9 to 1:11. Although acceptable coatings can be obtained when the metformin coat is applied directly to the membrane or sustained release coating, a preferred approach is to first coat the membrane or sustained release coating with a seal coat prior to the application of the metformin coating. As used herein a seal coat is a coating that does not contain an active pharmaceutical ingredient and that rapidly disperses or dissolves in water.
[0298] The metformin coating solution or suspension may also contain a surfactant and a pore forming agent. A pore forming is preferably a water-soluble material such as sodium chloride, potassium chloride, sucrose, sorbitol, mannitol, polyethylene glycols (PEG), propylene glycol, hydroxypropyl cellulose, hydroxypropyl methylcellulose, hydroxypropyl methylcellulose phthalate, cellulose acetate phthalate, polyvinyl alcohols, methacrylic acid copolymers, poloxamers (such as LUTROL F68, LUTROL F127, LUTROL F108 which are commercially available from BASF) and mixtures thereof.
[0299] In addition, various diluents, excipients, lubricants, dyes, pigments, dispersants, etc., which are disclosed in Remington's Pharmaceutical Sciences (1995), may be used to optimize the above listed formulations of the subject invention.
[0300] Biguanides, such as metformin are commonly administered in dosage forms containing 500 mg, 750 mg, 850 mg, and 1000 mg. Heal Brake hormone releasing substances, such as Brake, are commonly administered as individual controlled release tablets, and multiple tablets are combined in a single daily dose of between about 5.0 and 20.0, often about 7.5 and 15, often about 10 to about 12.5 grams of active ileal brake hormone releasing substances. The preferred embodiment of a combination of metformin and the ileal brake hormone releasing substance would overcoat 500 mg of metformin onto 7 tablets of the ileal brake hormone releasing core. Ideally, there would be about 70 mg of metformin overcoat on each of the 7 Brake tablets. The present invention is intended to encompass the above listed therapeutic combinations, without providing a specific example of each possible combination of compounds and their respective dosage amounts. It is noted that when agents other than or in addition to biguanides are utilized in combination with Brake, similar formulations may be provided with a controlled release ileal brake hormone releasing core and an overcoat of the additional bioactive agent(s) formulated for immediate or quick release.
[0301] Emulsions and microemulsions may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming, and preservative agents.
[0302] Suspensions, in addition to the ileal brake hormone releasing substance, may contain suspending agents such as ethoxylated isostearyl alcohols, polyoxyethylene sorbitol, and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.
[0303] Techniques for formulating the aforementioned useful dosage forms are either disclosed in the references cited above or are well-known to those of ordinary skill in the art. Stabilizing a subject's blood glucose and insulin levels means lowering the subject's blood glucose and insulin levels to healthy levels within normal or close to normal ranges.
[0304] The terms obesity and overweight are generally defined by body mass index (BMI), which is correlated with total body fat and estimates the relative risk of disease. BMI is calculated by weight in kilograms divided by height in meters squared (kg/m.sup.2). Normal BMI is defined as a BMI of about 18.5 to 24.9 kg/m.sup.2. Overweight is typically defined as a BMI of 25-29.9 kg/m.sup.2, and obesity is typically defined as a BMI of at least 30 kg/m.sup.2. See, e.g., National Heart, Lung, and Blood Institute, Clinical Guidelines on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults, The Evidence Report, Washington, D.C.: U.S. Department of Health and Human Services, NIB publication no. 98-4083 (1998). Obesity and its associated disorders are common and very serious public health problems in the United States and throughout the world. Central or Abdominal (18) adiposity is the strongest risk factor known for T2D and is a strong risk factor for cardiovascular disease. Central adiposity is a recognized risk factor for hypertension, atherosclerosis, congestive heart failure, stroke, gallbladder disease, osteoarthritis, sleep apnea, reproductive disorders such as polycystic ovarian syndrome, cancers of the breast, prostate, and colon, and increased incidence of complications of general anesthesia. Obesity reduces life-span and carries a serious risk of the co-morbidities listed above, as well as disorders such as infections, varicose veins, acanthosis nigricans, eczema, exercise intolerance, insulin resistance, hypertension hypercholesterolemia, cholelithiasis, orthopedic injury, and thromboembolic disease (18).
[0305] Because they specifically mimic the effects of RYGB surgery and thereby effectively treat, remediate or often cure metabolic syndrome, the present compositions are also useful for treating central adiposity, and favorably impact the conditions which often occur secondary to metabolic syndrome.
[0306] Once-daily administration to the subject of a delayed and/or controlled release dosage form includes self-administration of the dosage form by the subject.
[0307] The term coadministration is used to describe the administration of two or more active compounds, in a number of embodiments according to the present invention, in a pharmaceutical composition comprising at least one ileal brake hormone releasing substance in a first active composition and optionally, at least one second active composition formulated in the same pharmaceutical composition, often with different release characteristics as otherwise described herein. In a number of embodiments according to the present invention a first pharmaceutical composition (which may or may not contain an active other than the at least one ileal brake hormone releasing substance) may be administered with a second distinct pharmaceutical composition comprising an additional active agent to treat subjects according to the present invention. Although the term coadministration preferably includes the administration of two or more active compounds to the patient at the same time and often in one pharmaceutical composition comprising different release characteristics, it is not necessary that the compounds actually be administered at the exact same time, only that amounts of the different active compound will be administered to a patient or subject such that effective concentrations of the active compounds are found in the blood, serum or plasma, ileum or treated tissue at the same time.
[0308] Dietary components in the phrase wherein the nutritional substance comprises an enteric coated tablet or micro-encapsulation of glucose, lipids and dietary components, means any natural substance which either itself evidences impact on the ilea] brake, or alternatively, enhances the impact that glucose and/or lipids have on the ileal brake, such components including other complex carbohydrates and nutritional components as otherwise described herein including, for example, alfalfa leaf, chlorella algae, chlorophyllin and barley grass juice concentrate, among a number of other agents.
[0309] Combination therapy is ordinarily given as a treatment for the disclosed components of metabolic syndrome, and most patients are treated with statins and fish oils for their hyperlipidemia, metformin or DPP-IV inhibitors for their diabetes, ACE or AII inhibitors for their hypertension, phentermine containing or phentermine-topiramate products for weight loss, and mixtures of dietary supplements, vitamins, and the like. The present invention, by acting to release the metabolic regulatory hormones of the ileal brake, is designed to offer combination treatment to patients with an overall more successful control of the underlying metabolic syndrome and its various manifestations.

DESCRIPTION OF PREFERRED EMBODIMENTS AND METHODS
[0310] As summarized above, the system, diagnostics and pharmaceutical inventions disclosed provide treatment methods and organ regeneration methods for patients with metabolic syndromes including hyperlipidemia, weight gain, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states. These treatment methods can entail the calculation of indexes used to assess the severity of metabolic syndrome, such as FS index. Methods can further entail testing of biomarkers; testing of breath, blood or body fluid biomarkers and selection of pharmaceutical compositions to resolve one or more of the metabolic syndrome conditions including but not limited to hyperlipidemia, weight gain, hepatic steatosis, insulin resistance, hypertension, and atherosclerosis, fatty liver and chronic inflammatory states.
[0311] Thus, the invention provides a method of treatment of metabolic syndromes; wherein personalized treatments and pharmaceutical compositions are selected using the results of biomarker testing including but not limited to testing such as HBA1c, glucose GLP-1, PYY, GLP-2, insulin, Proinsulin, CRP, hsCRP, endotoxin, IL-6 and the like. Personalized treatment and pharmaceutical compositions can be selected using a Glucose Supply Side computerized algorithm and system, wherein said Glucose Supply Side treatment method for diabetes consists of an algorithm (incorporated herein in its entirety) ranking favorable attributes of pharmaceutical compositions acting by minimizing excess glucose inside cells, and minimizing the amount of glucose that reaches target cells of the metabolic syndrome afflicted patient.
[0312] The invention also provides a method of treatment of metabolic syndromes, wherein personalized treatment and pharmaceutical compositions are selected by comparison of biomarker behavior patterns between patients having responded to Roux-en-Y bariatric surgery and their own response to oral dosing with pharmaceutical formulations comprised of carbohydrates, lipids or amino acids which activate the ileal brake response of the ileum in a manner similar to RYGB surgery. The method specifically entails orally administered pharmaceutical compositions that mimic the action of RYGB surgery on the ileal brake.
[0313] Even more specifically, the formulation for treatment of metabolic syndrome comprises the micro-encapsulation of glucose, lipids and components of diet formulated to release these active compositions at pH values preferably between about 7.2 and 7.5, which targets the action of said medicaments at the ileal brake in the distal intestine. The encapsulated compositions disclosed are a preferred medicament to decrease appetite for glucose, and thereby lower inflammation and benefit to the treatment of patients with metabolic syndrome, according to the results of testing of targeted biomarkers.
[0314] In a preferred embodiment of a method of treatment of metabolic syndromes according to the invention, oral dosing with about 2,000 to 12,500 up to about 20,000, about 2500-3,000 to 10,000, about 7,500-10,000 milligrams of a pharmaceutical formulation of microencapsulated sugars, lipids, and/or amino acids activates the ileal brake in a dose increasing magnitude and treats one or more of the following components of metabolic syndrome: hyperlipidemia, weight gain, hepatic steatosis, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and chronic inflammatory states. The name of this medicament is Brake.
[0315] In another embodiment, the invention provides a pharmaceutical formulation for treatment of metabolic syndrome, wherein the microencapsulated activation of the ileal brake is produced at a pH of about 6.5 to about 7.5 and involves the release of about 2,000 to about 12,500 up to about 20,000, about 2,500-3,000 to 10,000, about 7,500 to 10,000 milligrams of glucose, fructose, dextrose, sucrose or other glucose compositions active on the ileal brake in mammals at dosages between about 2,000 and about 10,000-12,500 milligrams, and as presented above.
[0316] In another embodiment, the invention provides a pharmaceutical formulation wherein the microencapsulated activation of the ileal brake is produced by approximately pH 6.5 to 7.5 release of about 2,000 to about 6,000, about 2,500-3,000 to about 10, 000-12,500 milligrams of dextrose and about 2,000-4,000 milligrams of a lipid such as olive oil, corn oil, palm oil, omega3 fatty acid or other suitable lipid substances active on the ileal brake of mammals.
[0317] In one embodiment, a pharmaceutical formulation for treatment of metabolic syndrome of the invention can achieve the microencapsulated activation of the ileal brake at about pH 6.5 to 7.5 by release of about 2,000 to about 10,000-12,500 up to about 20,000, about 2,500-3,000 to about 10,000, about 7,500-10,000 milligrams given once, twice or three times daily.
[0318] In another embodiment, a method of treatment of metabolic syndromes according to the invention involves oral treatment and includes use of pharmaceutical formulations as described above that activate the ileal brake and which act in the gastrointestinal tract and the liver of a mammal to control metabolic syndrome manifestations, regenerate organs and tissues and thereby reverse or ameliorate the cardiovascular damage (atherosclerosis, hypertension, lipid accumulation, and the like) resulting from progression of metabolic syndrome.
[0319] In another preferred embodiment, a composition or a method of treatment of metabolic syndromes according to the invention involves an oral formulation mimetic of RYGB and includes use of said oral formulation over-coated with a second active agent, chosen from medicaments ordinarily used for treatments of separate manifestations of metabolic syndrome including but not necessarily limited to T2D, hyperlipidemia, atherosclerosis, hypertension, hepatic steatosis, insulin resistance, or chronic inflammation. The second active pharmaceutical agent can be, by way of specific example, metformin, sitagliptin, saxagliptin, methotrexate, olanzapine, donepezil, memantine, atorvastatin, simvastatin, lovastatin, olmesartan, Enalapril, lisinopril, candesartan, irbesartan, roflumilast, among others. Such compositions are the first to combine treatment of all of the primary metabolic syndrome manifestations into one product given once or twice daily to patients with all or many of the manifestations of metabolic syndrome, and the newly discoveredorgan regeneration capability is responsible for the long lasting efficacy of these medicament combination pharmaceuticals and in certain cases, an actual cure of the patient.
[0320] In a preferred example, a disclosed composition of the invention can act to limit hepatic gluconeogenesis in the same manner as metformin, as well as add pancreatic regeneration and many other actions beneficial to the treatment of metabolic syndrome. The class of compounds related to and including metformin is called biguanide antihyperglycemic agents. While metformin is illustrative, and the combination product therefrom is called MetaBrake, the list of biguanides is not exclusive beyond metformin, and additional metformin mimetic or biguanide medicaments can be added to the formulations of the invention without departing from the practice of treatments for metabolic syndrome that combine oral mimetics of RYGB surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by metformin. When used together with biguanide medicaments with particular emphasis on metformin, the dosage required to lower glucose, lipids, hepatic steatosis and inflammation may be reduced. When combined into an oral dosage form of Brake and a biguanide such as metformin, each of 7 tablets would contain about 1000 mg of ileal hormone releasing substances and 75 mg of metformin. In this manner the total dose of metformin per day would be about 500 mg and the ilea} hormone releasing substance would be less than about 10,000 mg, yet the combined product would control glucose, lower body weight, control triglycerides, lower systemic inflammation, and effect regeneration of organs and tissues, beneficial actions that are substantially beyond those of metformin alone.
[0321] In one aspect of a composition or a method of treatment of metabolic syndromes according to the invention, the second active pharmaceutical agent is from the class of DPP-N inhibitors, including but not limited to formulations whereby the composition acts in the same way as DPP-IV inhibitors and the like. Examples of similar orally administered agents, thought to act by inhibition of DPP-N, include Alogliptin, Vildagliptin, Sitagliptin, Dutogliptin, Linagliptin and Saxagliptin. While illustrative, this list is not meant to be exhaustive and it is readily apparent to persons skilled in the art of T2D care that additional DPP-IV inhibitors can be added to the formulations of the invention without departing from the practice of preparing oral treatments for metabolic syndrome that combine oral mimetics of RYGB surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by DPP-N inhibitors. When used together with so called DPP-IV inhibitors, the dosage required to lower glucose, lipids, triglycerides and inflammation may be reduced to the benefit of reduction of the side effects of DPP-N inhibitors, in particular the pancreatitis, which is presumed to be related to dosage of DPP-IV inhibitor chosen for treatment. When combined into an oral dosage form of Brake and a DPP-IV inhibitor such as sitagliptin, by way of example, each tablet would contain about 1000 mg of ileal brake hormone releasing substances and 10 mg of sitagliptin. In this manner the total dose of sitagliptin per day would be less than 100 mg, yet the combined product would, in a completely novel way, control glucose, lower body weight, control triglycerides, lower systemic inflammation and regenerate organs and tissues in a similar manner as RYGB surgery. This combination product of Brake and sitagliptin, called JanuBrake would be given once or twice daily and be suitable for consumer use of sitagliptin with an increased safety profile over that of sitagliptin alone. Similar gains in potency at lower doses, broad array of treatment responses in metabolic syndrome, and safety advantages over the statin alone would be seen with each of the DPP-IV inhibitors reduced to practice, and the disclosure of invention of a synergistic combination encompasses all DPP-IV inhibitor combinations with Brake prepared in this manner for these purposes.
[0322] In another aspect of a composition or a method of treatment of metabolic syndromes according to the invention, the second active pharmaceutical agent is from the class of insulin sensitizers, also known as TZDs or Thiazolidinediones which are also known to be active on PPAR. Examples of similar agents, thought to act on the defined insulin sensitizer pathway, include pioglitazone, rosiglitazone, rivoglitazone, aleglitazar and the PPAR-sparing agents MSDC-0160 MSDC-0602. While illustrative, this list is not meant to be exhaustive and it is readily apparent to persons skilled in the art that additional insulin sensitizers, thiazolidinediones or PPARs or PPAR-sparing medicaments can be added to the formulations of the invention without departing from the practice of oral treatments for metabolic syndrome that combine oral mimetics of RYGB surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by insulin sensitizers.
[0323] In another aspect of a composition or a method of treatment of metabolic syndromes according to the invention, the second active pharmaceutical agent is an alpha glucosidase inhibitor including but not limited to acarbose.

[0324] A composition or a method of treatment of metabolic syndromes according to the invention can also include the additional use of colesevelam, or can involve the use of a composition that acts in the gastrointestinal tract and on the ileal brake to limit glucose supply and to lower the lipid content of the blood in the same manner as colesevelam. While illustrative, the selection of a combination including colesevelam is not meant to be exhaustive and it is readily apparent that additional colesevelam mimetic medicaments can be added to the pharmaceutical composition of the invention without departing from the practice of oral treatments for metabolic syndrome that combine oral mimetics of RYGB surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by colesevelam.

Examples of similar agents, thought to act on the defined statin pathway or by HMG-CoA reductase inhibition, include atorvastatin, simvastatin, lovastatin, ceruvastatin, pravastatin. While illustrative, this list of available statin drugs is not meant to be exhaustive and it is readily apparent to persons skilled in the art that additional statins can be added to the formulations of the invention without departing from the practice of oral treatments for metabolic syndrome that combine oral mimetics of RYGB surgery effects on the ileal brake in conjunction with conventional anti-hyperlipidemic medicaments of the class represented by statins. When used together with so called statins, the dosage required to lower lipids and triglycerides may be reduced to the benefit of reduction of the side effects of statins, in particular the myopathy, which is known in the art to be related to higher dosages such as 80 mg of simvastatin. When combined into an oral dosage form of Brake and a statin such as atorvastatin, by way of example, each tablet would contain 1000 mg of ileal hormone releasing substances coated to release said ileal brake hormone releasing substances in the ileum and be over-coated with 2 mg of atorvastatin or a related agent in an effective amount with conventional release characteristics for targeted release in the duodenum. In this manner the total dose of atorvastatin per day would be less than 20 mg, yet the combined product would control glucose, lower body weight, control triglycerides, lower systemic inflammation, and regenerate organs and tissues. This product, called LipidoBrake would be given once or twice daily and be suitable for consumer use of atorvastatin with an improved safety profile over that of atorvastatin alone. Similar gains in potency at lower doses, a broad array of treatment responses in metabolic syndrome, and safety advantages over the statin alone would be seen with each of the statins reduced to practice, and the disclosure encompasses all statin combinations with Brake prepared in this manner for these purposes.

Example 1. Formulations for Pancreatic Regeneration to Improve T2D
[0370] The subject invention for treatment of T2D concerns a pharmaceutical formulation or dosage form comprising a first active drug comprising an ileal brake hormone releasing substance over-coated with an immediate or delayed release layer of a second active drug comprising, preferably, the antihyperglycemic drug metformin or a pharmaceutically acceptable salt thereof, alternatively sitagliptin or an alternative from the listing of available DPP-IV inhibitors as defined herein. The ileal brake hormone releasing substance is delivered in a controlled release manner from a tablet core, preferably an osmotic tablet core without a gelling or swelling polymer.
[0371] The composition of the tablet core should include the ileal brake hormone releasing substance and at least one pharmaceutically acceptable excipient. In one embodiment of the present invention the tablet core includes the ileal brake hormone releasing substance, a binding agent and an absorption enhancer, and the tablet core is preferably coated with a polymeric coating to form a membrane around the tablet. The tested formulations to be described herein have the following core composition:
TABLE-US-00001 Core Component Amount, mg Allowed Ranger, mg Alfalfa Leaf 3.00 1-10 Chlorella Algae 3.00 1-10 Chlorophyllin 3.00 1-10 Barely Grass Juice Concentration 3.00 1-10 D-glucose (Dextrose) 1429.00 500-3000 Corn Starch NF 80.00 25-160 Stearic Acid NF 19.50 6.5-35.sup. Magnesium Stearate NF 7.00 2.5-15.sup. Silicon Dioxide FCC 2.50 0.75-5.0
[0372] All inner core compositions were prepared identically for the single dose study, Briefly, the actives were mixed with corn starch, stearic acid, magnesium stearate and silicon dioxide and pressed into a tablet.
[0373] Seven different coatings were prepared and applied to the tablets. These are disclosed in the table below:
TABLE-US-00002 Formulation 1 10% Shellac Formulation 2 8% Shellac Formulation 3 10% Eudragit S Formulation 4 10% Nutrateric - Colorcon Formulation 5 10% Food Glaze Formulation 6 8% Food Glaze Formulation 7 6% Food Glaze
[0374] In this experiment, which was conducted in 45 volunteer subjects to define the specific formulation of Brake for use in patients as a mimetic of RYGB, each patient received a single dose of the test formulations prepared (coded 1-7 here) and the subsequent 10 hours was used to monitor blood concentrations of GLP-1, PYY, GLP-2, HOMA-IR, Proinsulin, C-pepT1De, Glucose, Leptin, IGF land IGF-2.
[0375]
[0376] The purpose of this pharmacology study was to define the impact of 7 different coating formulations on release of GLP-1 from human subjects, each tested for optimal coating to reach the ileal brake and release PYY and GLP-1. From these data, the formulation that provided the best pattern of GLP-1 and PYY was to be chosen for the subsequent clinical use study in patients to compare the oral use of Brake oral with RYOB surgery patients.
[0377] Under the stated calibration conditions, the selected formulation ideally would produce the same 0-10 hr AUC of GLP-1 as observed in a patient having RYGB surgery and illustrated as part of
[0378] The mean group AUC values for PYY and GLP-1 are provided in
[0379] After selecting formulation #2 for use in clinical studies, supplies were manufactured and clinical trials were organized and managed by the inventors. All clinical data presented herein were generated using formulation #2 from this experiment.
[0380] First Clinical Trials of Oral Brake Administration [0381] Study Design: Prospective use of Brake in patients, and retrospective comparison with RYGB patients [0382] 16 subjects with obesity and/or liver enzyme elevation treated with Brake [0383] Baseline and 6-month observations, with continued follow-up to date [0384] Control patients with serial measurements of FS index and taking pharmaceutical compositions suitable for combination with Brake
Methods: In separate protocols, RYGB and Brake treated subjects were identified and followed for a period of 6-months to identify changes in excess body weight (EBW), systolic blood pressure (SBP), diastolic blood pressure (DBP), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (TG), insulin, fasting plasma glucose (FPG), insulin resistance (HOMA-IR), hemoglobin A1C (HBA1c), liver function (AST, ALT) and renal function (SCr). Subjects with a baseline elevation in 1 metabolic biomarker and 6-month follow-up sampling data were included in the comparative analyses assessing metabolic restoration, medication discontinuation, and safety.
[0385] 6-Month Comparative Outcomes for RYGB and Brake [0386] Inclusion: Baseline elevation in >1biomarker with pre- and post-sampling [0387] (a) Excess body weight (>0 lbs) [0388] (b) Systolic blood pressure (>130 mmHg) [0389] (c) Diastolic blood pressure (>80 mmHg) [0390] (d) LDL cholesterol (>100 mg/dl) [0391] (e) HDL cholesterol (<50 mg/dl) [0392] (f) Triglycerides (>150 mg/dl) [0393] (g) Insulin (>10 uU/ml) [0394] (h) Fasting plasma glucose (>100 mg/dl) [0395] (i) Hemoglobin A1C (>6.5%) [0396] (j) HOMA-IR (>2) [0397] (k) AST I ALT (>25 U/J.) [0398] (l) Clinical Outcomes: [0399] (1) Improvement in weight and other metabolic biomarkers [0400] (2) % Restoration to metabolic targets [0401] (3) Medication requirements [0402] Statistical Analysis: Data are presented as MeanSD. Change from baseline was calculated and statistical analysis was performed by paired t-test.
[0403] Results: Expectedly, subjects undergoing RYGB had a profound restoration in all metabolic parameters: EBW (38%), SBP (100%), DBP (100%), LDL (94%), HDL (69%), TG (96%), insulin (77%), FPG (100%), HOMA-IR (83%), HBA1c, (100%), and liver enzymes AST (100%) and ALT (100%). Notably, these effects occur with a reduction of antihypertensive, antihyperlipidemic, and antidiabetic medication use. On the other hand, Brake treated patients did not experience major weight loss. Accordingly, it was unexpected that Brake treated subjects demonstrated effects on FS index parameters that were almost the same as the effect of RYGB: EBW (40%), SBP (59%), DBP (100%), LDL (72%), HDL (140%), TG (92%), insulin (68%), PPG (64%), HOMA-IR (46%),AST (73%), and ALT (68%). These data are found in
[0404] Concomitant medications were not discontinued in Brake treated subjects, although few were on medications for T2D. No change in serum creatinine was detected, either in RYGB or Brake treated subjects.
[0405] Conclusions: [0406] (1) RYGB induced statistically significant reduction in excess body weight and a profound restorative effect on all evaluated metabolic biomarkers over the 180-day monitoring period of this study. Normalizing all of the FS index parameters leads to the surprising conclusion of regeneration of pancreas, liver and GI tract in these patients. [0407] (2) Brake in a daily dosage of 7 pills of formulation 2, induced statistically significant reduction in excess body weight, blood pressure, hypertriglyceridemia, fasting plasma glucose, and liver enzymes over the 180-day monitoring period of this study. [0408] (3) In comparison to RYGB, the daily dose of 7 pills, about 10 gm of the dextrose formulation of Brake induced unexpected similar metabolic effects on blood pressure, lipids, and liver enzymes, since body weight did not decrease to the same extent as with RYGB surgery. Comparative effect on excess body weight (41%), insulin resistance (45%), and blood glucose (64%) were a lesser percentage of RYGB. Medications were only discontinued in RYGB. Neither RYGB nor Brake increased serum creatinine. [0409] While not as profound as RYGB, Brake induces statistically significant weight loss and improvements in blood pressure, lipids, glucose, and insulin resistance. Liver enzymes indicative of NAFLD are improved significantly in both groups. These relative changes establish the SD ratio of RYGB as 4.0 and the SD ratio of Brake at 3.5.
[0410] Overall, while not as profoundly associated with weight loss as RYGB, Brake is clearly responsible for statistically significant improvements in hypertension, hyperlipidemia, hyperglycemia, hepatic inflammation, and insulin resistance. In each of these cases where a component of metabolic syndrome establishes elevated CV risk, Brake was similarly effective to RYGB surgery, meaning that these outcomes were not dependent on weight loss to be beneficial to the patient with elevated CV risk due to metabolic syndrome. Previous investigators in this field have been generally unwilling to recognize that CV risk is not due to obesity directly, even in the face of this strong evidence.
[0411] Study of ileal brake hormone derived biomarkers such as GLP-1, allow a demonstration of the ileal brake differences associated with obesity, T2D, and of course the effect of RYGB. In brief, weight gain proceeds as the ileal brake is put to sleep, it becomes hypo-responsive as the patient develops greater central adiposity and the syndrome progresses to T2D, NAFLD, hypertension and ASCVD in patients afflicted by metabolic syndrome. The pancreas response to this progressive loss of ileal brake control is a decline in output of insulin, eventually failing to keep up with the glucose supply coming in from the diet (Monte, US 2011/0097807, now U.S. Pat. No. 8,367,418). It is this process in the precise anatomical location of the ileal brake, that RYGB, and our Brake product wakes up and restores, which is the initial event in regeneration of organs and tissues.
[0412] We have summarized GLP-1 responses in the various conditions in
[0413] Until some work recently performed by us using the SmartPill, there was no explanation for why the obese and obese T2D patient had low output of the ileal brake, as caused by its state of capable of normal response to stimulation (as shown by RYGB) but choosing not to respond.
[0414] We used SmartPill (SmartPill Corporation, USA) to analyze segmental differences between the ileal brake sites in normal, obese subjects and obese patients with T2D, the differences between the pH values in the ileum of these different populations were profound and unexpected. Basically, as shown in
[0415] These intestinal segment changes in pH seen in different patient populations are consistent with shifts in the probiotic bacterial populations among diabetics and obese patients, as shown by recent work using stool samples as starting material (19, 20)
[0416] There were novel and important discoveries in these studies that led to key refinements during development of the Brake product. Specifically, we learned that the target pH for release of the formulation contents must be optimized to the values of the sleeping ileal Brake in aT2D patient, those between about 7.2 and 7.5. Had we targeted 7.7 to 8.0 which is a normal pH value in non-obese persons, the product would not release in the ileum of these patients and thus not have an effect on the precise patient population we were treating, and indeed would likely not be released at all. Secondly, we learned that the major defect of the ileal Brake in T2D patients is not atrophy of the L-cells themselves, rather the problem is a lack of signaling. The absence of signal has three novel causes. First, the dietary ingestion of refined sugars leads to a huge bolus of glucose from the duodenum, but surprisingly it is all absorbed by the duodenum and as a result, none of this sugar load reaches the ileum to trigger satiety and/or any of the other beneficial responses to activation of the ileal brake, such as repair and regeneration of pancreas, liver and GI tract. This hyperstimulation of insulin output from a diet of highly refined and immediately available sugar is a primary reason for pancreatic exhaustion involving metabolic syndrome and the eventual collapse of pancreatic beta cell insulin production. The absence of an ileal brake signal to regenerate beta cell mass is a consequence of the rapidly absorbed high duodenal load of sugar. This refined sugar fast forward pathway to central adiposity and eventual T2D may be termed the glucose supply pathway to T2D, which now appears to progress unopposed by the ileal brake. The ileal brake is quiescent if there is no glucose reaching the ileum to signal the brake, and the consequences are rapid weight gain and pancreatic exhaustion.
[0417] Secondly, with regard to signaling itself, clearly the intestinal flora change and perhaps become active themselves in signaling the ileal brake to be quiet.(21-26) This is of course in their own self-interest, as a quiet ileal brake means that ingestion to excess available calories continues, increasing the chances of the increased flora for receiving more downstream nutrition, further accelerating their growth. More bacteria, lower ileal pH and thus more signal to the ileal brake to become quiet. The result is more hunger signal, more ingestion of sugar and fats, and consequently central adiposity with high insulin output, termed of course, insulin resistance. Thus we have learned for the first time how the sensor called the ileal brake is integral to the pathogenesis of metabolic syndrome and T2D, via bacterial flora and the type of diet that has been called the western diet high in refined sugars and fats, all optimized for rapid absorption and high insulin release.
[0418] Hyperglycemia and hyperlipidemia are almost unavoidable in this fast forward nutrition driven cycle, and the only aspect that can be recovered is the ileal brake, which has RYGB as a primary means of awakening via L-cell stimulation, and now our discovery of an oral mimetic, the product herein called Brake.
[0419] All of these findings are also evident with Brake treatment, and we did make the observation in one of our patients who discontinued Brake treatment, that her T2D did not return for a prolonged period of time after stopping Brake, and only after she began once again to gain weight. So it is possible to conclude that Brake is also producing an improvement in insulin secretory capability and that is the reason why Brake, like RYGB, can restore previously lost pancreatic functionality, an unexpected result. This is a novel finding, completely unexpected in particular because these Brake treated patients lost much less weight than RYGB patients, and most workers in this field of T2D posit that weight loss is the mechanism of improvement in T2D. It is clear from our findings that pancreatic regeneration or renewal is an important and previously undiscovered attribute of precise stimulation of the L-cells of the ileal Brake.
[0420] In studies conducted by the inventors with the formulation claimed herein, diabetic patients with elevated HBA1c had nearly complete return to normal HBA1c values when treated longer than 6 months. Of most significance, patients could stop their treatment with the Brake formulation, yet their T2D did not return until after considerable weight re-gain and a return of the metabolic syndrome that caused it in the first place. Demonstration of a prolonged and persistent effect is further evidence of pancreatic beta cell regeneration or at least an increase in functional beta cell mass, and we claim this novel pathway as a beneficial attribute of the oral mimetic of RYGB.
[0421] A similar profile of hormones are released from the L-cells in the distal intestine regardless of whether the release is caused by RYGB or by the ileal Brake releasing substance disclosed herein as Brake.
[0422]
[0423] From these testing procedures, formulation #2 was chosen for treatment of metabolic syndrome in patients, and all clinical data presented herein was generated using formulation #2 from this experiment.
Example 2. Pancreatic Beta Cell Regeneration with MetaBrake
[0424] Metformin is the mainstay treatment for T2D worldwide, and all biguanides show a dose related lowering of hyperglycemia. Some studies with metformin in T2D patients have shown a reduction in cardiovascular risk profile. This may be achieved by glucose lowering or it may be result of modest weight reduction, or both. Metformin alone is not known to regenerate the pancreas or liver in patients with T2D nor does it directly impact the cardiovascular system or the vascular endothelin. When we examined our control patients treated with metformin, we confirmed that there was no significant change in any of the parameters that would indicate regeneration, even at dosages of 2.0 grams daily. Specifically, FS index rises on metformin alone, and there is a slow loss of control of their T2D in all parameters. See
[0425] RYGB surgery on the other hand, has a major effect on pancreatic regeneration, a modest lowering of cholesterol, and a dramatic evidence of organ and tissue regeneration, providing sufficient amounts of new beta cell formation so that RYGB patients can be removed from insulin therapy within days of the surgical procedure. One aspect of the greater effect of RYGB surgery is its impact across the dietary supply side pathways of sugar and fat, T2D and hyperlipidemia. Evidence favoring the combination approach of an orally active RYGB mimetic with metformin is provided in
[0426] Metformin is an example of an optimal medicament to use in combination with Brake. Metformin, which decreases hepatic gluconeogenesis, acts on the glucose supply side of the nutritional pathways of the ileal brake. Metformin is ideally given in combination with Brake in a dosage lower than metformin when given alone. In the combination product, Brake acts the distally in the same way as RYGB surgery. There is the same sensation of a malabsorptive emergency the same activation of L-cells, the output of which produces regeneration and makes hunger for sugar and fats quickly disappear. In this case the additional benefit of metformin is some additional activation of the L-cell pathway and a decrease in the amount of glucose synthesized by the liver. Otherwise the coordinates of the response model are the same as RYGB surgery or Brake alone.
[0427] By way of example, when apportioning the daily dose of metformin onto the daily dose of ileal brake hormone releasing substance in the enteric coated tablet form, the 1.0 gram tablets are over-coated with the immediate release metformin in a weight ratio of approximately 0.025 to 0.10 parts metformin to each 1.0 part refined sugar, optimally 0.05 parts metformin to each 1.0 part refined sugar; and/or the enteric coated core of the pharmaceutical composition may also comprise approximately 60-80% dextrose and 0-40% of a plant-derived lipid
[0428] Use of the disclosed treatments and methods for regeneration of pancreatic beta cells are based on the findings which are presented herein.
[0429] By way of illustrative example of the regenerative effect of RYGB or its oral mimetic Brake on T2D, consider the diagram shown as
[0430] One female subject, LJ-1, was initially controlled on 2.0 grams of metformin daily and 7 Brake tablets. She lost 32 lbs on this combination. Subsequently, she stopped losing weight but was otherwise pleased with the response to the combination. She was converted to 500 mg of metformin daily and felt even better taking the lower dose of metformin.
[0431] Weight loss resumed and it was felt by the inventors that metformin dosage reduction should be part of all patients' combinations, since patients have fewer metformin side effects at the 500 mg daily dose when compared with the usual dose of 2.0grn.
[0432] Logically, any agent which augments the processes involved in increasing pancreatic beta cell mass are logical to combine with Brake in order to further augment the impact on the pancreas. Metformin combinations therefore are important, particularly in view of their surprising efficacy at a lower dose of metformin (low dose metformin) than that used conventionally as monotherapy. It is also novel to combine Brake with lower that typical doses of DPP-IV inhibitors such as sitagliptin, particularly in view of the GLP-1data in
[0433] When combined into an oral dosage form of 7 Brake tablets overcoats with a DPP-IV inhibitor such as sitagliptin, by way of example, each tablet would contain about 1000 mg of ileal brake hormone releasing substances and 10 mg of sitagliptin. In this manner the total dose of sitagliptin per day would be less than 100 mg (low dose sitagliptin), yet the combined product would, in a completely novel way, control glucose, lower body weight, control triglycerides, lower systemic inflammation and regenerate organs and tissues in a similar manner as RYGB surgery. This combination product of Brake and sitagliptin, called JanuBrake would be given once or twice daily and be suitable for consumer use of sitagliptin with an increased safety profile over that of sitagliptin alone. Similar gains in potency at lower doses, broad array of treatment responses in metabolic syndrome, and safety advantages over the statin alone would be seen with each of the DPP-IV inhibitors reduced to practice, and the disclosure of invention of a synergistic combination encompasses all DPP-IV inhibitor combinations with Brake prepared in this manner for these purposes.
[0434] Patient MF was a 49 year old female with a history of chronic hepatitis B, her liver biopsy showed steatosis with stage 1/4 fibrosis. Both her Triglycerides and hepatic enzymes were 2-3 elevated. She had T2D on Metformin and a sulfonylurea with a baseline HBA1c of 7.4. Her diabetic control deteriorated on this regimen, to the point where she was considered a candidate for insulin. As an alternative, patient was started on Januvia (sitagliptin) 100 mg per day and 7 pills of Brake. After 6 months treatment, her HBA1c became normal at 6.0, indicating pancreatic regeneration from the combination product. She also had nearly complete normalization of her AST, triglycerides and Alpha-fetoprotein in this same timeframe. She lost 35 lbs. Her course is shown in
[0435] The initial disclosed combination product in this invention is low dose metformin wherein 500 mg of immediate release metformin is over-coated onto 10 gm of the controlled release ileal brake hormone releasing substance, and the pharmaceutical composition is recommended for 3-6 months of treatment at a minimum to achieve the maximum regeneration of pancreas, liver and GI tract. Some examples of patients treated with metformin and Brake together, but as separate pills are presented in
[0436] In particular, the present invention generally proceeds when the steps in practice of the invention include the testing the patient for laboratory biomarker patterns, use of the results of testing to calculate the PS index, determining the risk of organ damaging events from the FS index calculation (when the FS index measures at least about 60, 100, 150, 200, 300, 400 or 500 and above), then the application of personalized treatment to lower the FS index, most preferably by the administration of a pharmaceutical composition targeted to a specific receptor (on the L-cells) in the distal intestine, in a dosage and duration of treatment to lower the FS index of the patient upon repeat measurements.
[0437] The effect of said medicament on the measured biomarkers demonstrates beneficial properties of the ileal brake hormone releasing substance on the laboratory tests that comprise the FS index. In the ordinary assessment of the precise sequence of hormonally produced events, the patient experiences cessation of hunger. The patient benefits from the ileal brake hormone release with regeneration of organs and tissues, typically pancreas, liver and gastrointestinal tract.
[0438] With respect to the sequence of signaling molecules from the ileum, a response to the medicament entails a wake up stimulation of distal intestinal L-cells that have been quieted by actions of intestinal bacteria or metabolic disease; there is a release of hormones and signals from said L-cells; said released hormones traveling in portal blood to pancreas, liver and GI tract, said organs regenerated from available growth factors and hormone signals, measured biomarkers of the FS index demonstrating the successful regeneration and said regenerated organs then signaling the patient, preferably a human, to resume adequate nutrition seeking behavior as directed by restored signals of hunger.
[0439] It is notable that the weight loss is always greater with RYGB surgery, even though surprisingly the organ and tissue regeneration profiles are quite similar between metformin given with either RYGB or with Brake. Neither metformin alone nor atorvastatin alone as control cases demonstrate resolution of metabolic syndrome manifestations. Atorvastatin effects will be discussed further in example 5.
[0440] Other agents are suitable for combination with Brake tablets in the regeneration of the pancreas in T2D, and these are disclosed and incorporated into the invention by reference. Some examples follow. It is noted that these other agents are preferably formulated in combination with the ileal hormone stimulating substance (Brake) at substantially lower doses than when these same agents are administered to a subject alone (in the absence of Brake), resulting in reduced toxicity with superior therapeutic effect.
[0441] The investigators examined the role of flavonoid rich fraction (FRF) of Oreocnide integrifolia leaves using a mouse model of experimental regeneration. BALB/c mice were subjected to 70% pancreatectomy (Px) and supplemented with FRF for 7, 14, and 21 days after pancreatectomy. Px: animals displayed increased blood glucose levels and decreased insulin titers which were ameliorated by FRF supplementation. FRF-treated mice demonstrated prominent newly formed islets budding off from ducts and depicting increased BrdU incorporation. Additionally, transcripts levels of Ins1/2, Reg 3alpha/gamma, Ngn-3, and Pdx-1were up-regulated during the initial 1 week. The present study provides evidence of nutraceutical contributing to islet neogenesis from ductal cells as the mode of beta-cell regeneration and a potential therapeutic for clinical trials in management of diabetic manifestations(27)
[0442] The antihyperglycemic function of ginsenoside Rh2 (GS-Rh2) was studied on the regeneration of beta-cells in mice that underwent 70% partial pancreatectomy (PPx). The investigators explored the mechanisms of GS-Rh2-induced beta-cell proliferation. Adult C57BL/6J mice were subjected to PPx or a sham operation. Within 14 days post-PPx, mice that underwent PPx received GS-Rh2 (1 mg/kg body weight) or saline injection. GS-Rh2-treated mice exhibited an improved glycemia and glucose tolerance, an increased serum insulin levels, and beta-cell hyperplasia. Meanwhile, increased beta-cell proliferation percentages and decreased beta-cell apoptosis percentages were also observed in GS-Rb2-treated mice. Further studies on the Akt/Foxo1/PDX-1 signaling pathway revealed that GS-Rh2 probably induced beta-cell proliferation via activation of Akt and PDX-1 and inactivation of Foxo1. Studies on the abundance and activity of cell cycle proteins suggested that GS-Rh2-induced beta-cell proliferation may ultimately be achieved through the regulation of cell cycle proteins. These findings demonstrate that GS-Rh2 administration could inhibit the tendency of apoptosis, and reverse the impaired beta-cell growth potential by modulating Akt/Foxo1/PDX-1 signaling pathway and regulating cell cycle proteins. Induction of islet beta-cell proliferation by GS-Rh2 suggests its therapeutic potential in the treatment of T2D.(28)
[0443] Betacellulin (BTC), a member of the epidermal growth factor family, is known to play an important role in regulating growth and differentiation of pancreatic beta cells. Growth-promoting actions of BTC are mediated by epidermal growth factor receptors (ErbBs), namely ErbB-1, ErbB-2, ErbB-3 and ErbB-4; however, the exact mechanism for beta cell proliferation has not been elucidated. Therefore, we investigated which ErbBs are involved and some molecular mechanisms by which BTC regulates beta cell proliferation. The expression of ErbB-1, ErbB-2, ErbB-3, and ErbB-4 mRNA was detected by RT-PCR in both a beta cell line (MIN-6 cells) and C57BL/6 mouse islets. Immunoprecipitation and western blotting analysis showed that BTC treatment of MIN-6 cells induced phosphorylation of only ErbB-1 and ErbB-2 among the four EGF receptors. BTC treatment resulted in DNA synthetic activity, cell cycle progression, and bromodeoxyuridine (BrdU)-positive staining. The proliferative effect was blocked by treatment with AG1478 or AG825, specific tyrosine kinase inhibitors of ErbB-1 and ErbB-2, respectively. BTC treatment increased mRNA and protein levels of insulin receptor substrate-2 (IRS-2), and this was blocked by the ErbB-1 and ErbB-2 inhibitors. Inhibition of IRS-2 by siRNA blocked cell cycle progression induced by BTC treatment. Streptozotocin-induced diabetic mice injected with a recombinant adenovirus expressing BTC and treated with AG1478 or AG825 showed reduced islet size, reduced numbers of BrdU-positive cells in the islets, and did not attain BTC-mediated remission of T2D. These results suggest that BTC exerts proliferative activity on beta cells through the activation of ErbB-1 and ErbB-2 receptors, which may increase IRS-2 expression, contributing to the regeneration of beta cells.(29)
[0444] Transgenic expression of gastrin and EGF receptor ligands stimulates islet neogenesis in adult mice. significantly increasing islet mass. The present study aimed to determine whether pharmacological treatment with gastrin and EGF can significantly stimulate beta-cell regeneration in chronic, severe insulin-dependent T1D. In this experiment, T1D was induced by intravenous streptozotocin, resulting in >95% beta cell destruction. Four weeks later, blood glucose levels were restored to normal range by exogenous insulin therapy and rats were treated with EGF/gastrin in combination, gastrin alone, or EGF alone given subcutaneously. After 14 days treatment blood glucose was significantly lower in the EGF/gastrin group compared to the untreated diabetic controls. Along with improved glucose tolerance, EGF/gastrin treatment significantly increased plasma C pepT1De and pancreatic insulin content compared to diabetic controls. Histological analysis showed that EGF/gastrin treatment significantly increased beta-cell mass as determined by point counting morphometrics. The EGF/gastrin group had a significantly greater number of BrdU labeled beta-cells/section consistent with stimulation of beta-cell replication or neogenesis. An increased number of gastrin receptor positive cells were observed in the EGF/gastrin-treated groups. In contrast to the effectiveness of the EGF/gastrin combination, neither gastrin nor EGF alone improved glucose tolerance in severely streptozotocin-diabetic rats. These studies indicate that physiologically significant improvement in glucose tolerance can be achieved through stimulating beta-cell regeneration with gastrin/EGF administered systemically as conventional pharmacological therapy.

[0445] Investigations in NOD mouse models show evidence of pancreatic regeneration in response to GLP-1 agonists alone, and in fact the combination of Gastrin releasing drugs like lansoprazole and the DPP-IV inhibitor sitagliptin (which elevates GLP-1 after ileal brake stimulation) also causes pancreatic beta cell regeneration.
[0446] Combination therapy with a clipeptidyl peptidase-IV inhibitor (DPP-IV) and a protonpump inhibitor (PPI) raises endogenous levels of GLP-1 and gastrin, respectively, and restores pancreatic beta-cell mass and normoglycemia in non obese diabetic (NOD) mice with autoimmune diabetes. The aim of this study was to determine whether a DPP-IV and PPI combination could increase beta-cell mass in the adult human (31) pancreas. Pancreatic cells from adult human pancreas donors were implanted in NOD-severe combined immunodeficient (NOD-acid) mice and the mice were treated with a DPP-IV and a PPI for 16 weeks. Human grafts were examined for insulin content and insulin-stained cells. Graft beta-cell function was assessed by intravenous glucose tolerance tests (IVGIT) and by glucose control in human cell-engrafted mice treated with streptozotocin (STZ) to delete mouse pancreatic beta-cells. Plasma GLP-1 and gastrin levels were raised to two- to threefold in DPPIV and PPI-treated mice. Insulin content and insulin-stained cells in human pancreatic cell grafts were increased 9- to 13-fold in DPP-4i and PPI-treated mice and insulin-stained cells were co-localized with pancreatic exocrine duct cells. Plasma human C-pepT1De responses to IVGIT were significantly higher and STZ-induced hyperglycemia was more completely prevented in DPP-IV- and PPI-treated mice with grafts than in vehicle-treated mice with grafts. In conclusion, DPP-IV and PPI combination therapy raises endogenous levels of GLP-1 and gastrin and greatly expands the functional beta-cell mass in adult human pancreatic cells implanted in immunodeficient mice, largely from pancreatic duct cells. This suggests that a DPP-IV and PPI combination treatment may provide a pharmacologic therapy to correct the beta-cell deficit in T1D.(31)
[0447] IGF-2
[0448] Insulin-like growth factor-II (IGF2) is a growth promoting pepT1De that increases beta cell proliferation and survival. The aim of the study was to determine the effect of IGF2 overexpression on beta cell mass in transplanted islets. Islets infected with adenovirus encoding for IGF2 (Ad-IGF2 group), for luciferase (Ad-Luc control group) or with uninfected islets (control group) were syngeneically transplanted to streptozotocin-diabetic Lewis rats. 800 islets, a minimal mass-model to restore normoglycemia, or 500 islets, a clearly insufficient mass, were transplanted. Rats transplanted with 800 Ad-IGF2 islets showed a better metabolic evolution than control groups. As expected, rats transplanted with 500 Ad-IGF2 or control islets maintained similar hyperglycemia throughout the study ensuring comparable metabolic conditions among both groups. Beta cell replication was higher in Ad-IGF2 group than in control group on days 3 (1.45% (JQR: 0.26) vs. 0.58% (IQR: 0.18), p=0.006), 10 (1.58% (IQR: 1.40) vs. 0.90% (IQR: 0.61), p=0.035) and 28 (1.35% (IQR: 0.35) vs. 0.64% (IQR: 0.28), p=0.004) after transplantation. Beta cell mass was similarly reduced on day 3 after transplantation in Ad-IGF2 and control group (0.36 mg (IQR: 0.26) vs. 0.38 mg (IQR: 0.19)], it increased on day 10, and on day 28 it was higher in Ad-IGF2 than in control group (0.63 mg (IQR: 0.38) vs. 0.42 mg (IQR: 0.31), p=0.008). Apoptosis was similarly increased in Ad-IGF2 and control islets after transplantation. No differences in insulin secretion were found between Ad-IGF2 and uninfected control islets. In summary, IGF2 overexpression in transplanted islets increased beta cell replication, induced the regeneration of the transplanted beta cell mass, and had a beneficial effect on the metabolic outcome reducing the beta cell mass needed to achieve normoglycemia.(32)
[0449] Meier et al investigated whether there was evidence of attempted beta cell regeneration in the pancreas obtained from a patient with recent-onset T1D, and if so by what mechanism this occurred. They examined pancreas tissue from a Jean 89-year-old patient (BMI 18.0 kg/m.sup.(2)) with recent-onset T1D who had had a distal pancreatectomy to remove a low-grade pancreatic intraepithelial neoplasia. In the tumor-free tissue, the fractional beta cell area was 0.54+/0.2% of pancreas area (about one-third of that in non-diabetic humans). CD3-positive T lymphocytes and macrophages had infiltrated the majority of the islets. Sub-classification of the T cell population revealed a predominance of CDS-positive cells over CD4-positive cells. Beta cell apoptosis (terminal deoxynucleoTlDyl transferase-mediated dUTP-biotin nick-end labeling [TUNEL] staining) was greatly increased, consistent with ongoing immune-mediated beta cell destruction. There was also a marked increase (more than approximately 100-fold) in the frequency of beta cell replication (0.69+/0.15% Ki67-positive beta cells) in all blocks examined. The present report provides direct evidence of attempted beta cell regeneration through the mechanism of beta cell replication in a case of newly diagnosed TID, and affirms that beta cell apoptosis is an important mechanism for beta cell Joss in T1D.(33)
[0450] There is controversy regarding the roles of bone marrow (BM)-derived cells in pancreatic beta-cell regeneration. To examine these roles in vivo, mice were treated with streptozotocin (STZ), followed by bone marrow transplantation (BMT; lethal irradiation and subsequent BM cell infusion) from green fluorescence protein transgenic mice. BMT improved STZ-induced hyperglycemia, nearly normalizing glucose levels, with partially restored pancreatic islet number and size, whereas simple BM cell infusion without pre-irradiation had no effects. In post-BMT mice, most islets were located near pancreatic ducts and substantial numbers of bromodeoxyuridine-positive cells were detected in islets and ducts. Importantly, green fluorescence protein-positive, i.e. BM-derived, cells were detected around islets and were CD45 positive but not insulin positive. Then to examine whether BM-derived cell mobilization contributes to this process, we used Nos3(/) mice as a model of impaired BM-derived cell mobilization. In streptozotocin-treated Nos3(/) mice, the effects of BMT on blood glucose, islet number, bromodeoxyuridine-positive cells in islets, and CD45-positive cells around islets were much smaller than those in streptozotocin-treated Nos3(+/+) controls. A series of BMT experiments using Nos3(+/+) and Nos3(/) mice showed hyperglycemia-improving effects of BMT to correlate inversely with the severity of myelosuppression and delay of peripheral white blood cell recovery. Thus, mobilization of BM-derived cells is critical for BMT-induced beta-cell regeneration after injury. The present results suggest that homing of donor BM-derived cells in BM and subsequent mobilization into the injured periphery are required for BMT-induced regeneration of recipient pancreatic beta-cells.(34)
[0451] Type 1diabetes (T1D) is an autoimmune disease in which the clinical onset most frequently presents in adolescents who are genetically predisposed. There is accumulating evidence that the endocrine pancreas has regenerative properties, that hematopoietic chimerism can abrogate destruction of beta cells in autoimmune T1D, and that, in this manner, physiologically sufficient endogenous insulin production can be restored in clinically diabetic NOD mice. Recapitulating what also has been seen sporadically in humans, these authors set out to test reliable and clinically translatable alternatives able to achieve these same goals. Recently, Tian and colleagues demonstrated that T1D can be prevented in genetically susceptible mice by substituting a diabetes-susceptible class II MHC beta chain with a diabetes-resistant allelic transgene on their hematopoietic stem cells through gene supplantation. The expression of the newly formed diabetes-resistant molecule in the re-infused hematopoietic cells was sufficient to prevent T1D onset even in the presence of the native, diabetogenic molecule. If this approach to obtain autoimmunity abrogation could facilitate a possible recovery of autologous insulin production in diabetic patients, safe induction of an autoimmunity-free status might become a new promising therapy for T1D.(35)
[0452] T1D is widely held to result from an irreversible loss of insulin-secreting beta cells. However, insulin secretion is detectable in some people with long-standing TID, indicating either a small population of surviving beta cells or continued renewal of beta cells subject to ongoing autoimmune destruction. The aim of the present study was to evaluate these possibilities. Pancreatic sections from 42 individuals with T1D and 14 non-diabetic individuals were evaluated for the presence of beta cells, beta cell apoptosis and replication, T lymphocytes and macrophages. The presence and extent of periductal fibrosis was also quantified. Beta cells were identified in 88% of individuals with T1D. The number of beta cells was unrelated to duration of disease (range 4-67 years) or age at death (range 14-77 years), but was higher (p<0.05) in individuals with lower mean blood glucose. Beta cell apoptosis was twice as frequent in T1D as in control subjects (p<0.001), but beta cell replication was rare in both groups. The increased beta cell apoptosis in T1D was accompanied by both increased macrophages and T lymphocytes and a marked increase in periductal fibrosis (p<0.001), implying chronic inflammation over many years, consistent with an ongoing supply of beta cells. Most people with long-standing T1D have beta cells that continue to be destroyed. The mechanisms underlying increased beta cell death may involve both ongoing autoimmunity and glucose toxicity. The presence of beta cells despite ongoing apoptosis implies, by definition, that concomitant new beta cell formation must be occurring, even after long-standing T1D. These authors concluded that T1D may be reversed by targeted inhibition of beta cell destruction(36). Both RYGB and Brake therapy are expected to accomplish this task to at least a limited degree in T1D, and these benefits will be observed by decline in FS index values when they are treated with these modalities.
[0453] Programmed cell death (PCD) is a key phenomenon in regulating cell-numbers. Apoptosis is essentially required for a balanced homeostasis between cell proliferation and cell death in multicellular organisms. Apoptosis is especially relevant in the gastrointestinal tract, as the mammalian intestinal mucosa undergoes continual epithelia cell turnover.(37)
[0454] Amyloid
[0455] T2D is a multifactorial disease in which pancreatic islet amyloid is a characteristic histopathological finding. Islet amyloid fibrils consist of the beta-cell protein islet amyloid polypeptide (1APP)/amylin. Unlike human IAPP (hIAPP), mouse IAPP cannot form amyloid. In previously generated transgenic mice, high expression of hIAPP as such did not induce islet amyloid formation. To further explore the potential diabetogenic role of amyloidogenic JAPP, these authors introduced a diabetogenic trait (ob mutation) in hIAPP transgenic mice. METHODS: Plasma concentrations of IAPP. insulin and glucose were determined at 3.5 (t1), 6 (t2), and 16-19 months of age (t3). At t3, the mice were killed and the pancreas was analyzed immunohistochemically. RESULTS: In non-transgenic ob/ob mice, insulin resistance caused a compensatory increase in insulin production, normalizing the initial hyperglycemia. In transgenic ob/ob mice, concurrent increase in hIAPP production resulted in extensive islet amyloid formation (more often and more extensive than in transgenic non-ob/ob mice), insulin insufficiency and persistent hyperglycemia: At t3, plasma insulin levels in transgenic ob/ob mice with amyloid were fourfold lower than in non-transgenic ob/ob mice (p<0.05), and plasma glucose concentrations in transgenic ob/ob mice were almost twofold higher (p<0.05). In addition, the degree of islet amyloid formation in ob/ob mice was positively correlated to the glucose: insulin ratio (r(s)=0.53, p<0.05). Islet amyloid is a secondary diabetogenic factor which can be both a consequence of insulin resistance and a cause of insulin insufficiency(38).
[0456] It is quite clear from the extensive prior studies in animal models of diabetes, summarized earlier in this example, that a biomarker approach can be relied upon to demonstrate favorable effects of RYGB surgery and/or the compositions according to the present invention (Brake) on pancreatic regeneration. Based on the unexpected but highly beneficial improvement in biomarkers and improved beta cell functioning after RYGB, it is a therapeutic approach to treat early diabetes with a novel combination oral therapy of a diabetes drug, nominally for the first demonstration, metformin and Brake. In this therapeutic approach, every patient would receive Brake treatment that would be demonstrated to be active on the basis of lowered biomarkers of diabetes in a pattern of elevation similar to that observed in our RYGB patients. In combination with oral Brake treatment as disclosed herein, the patient would also receive an approved front line treatment for diabetes such as metformin, sitagliptin, or pioglitazone, any of these therapeutic substances could be given in the usual dose or in some novel regimens, given at less than half the usual dose. There are two tested reasons that Brake would improve both the efficacy and safety of metformin or sitagliptin in the treatment of diabetes. First, both agents have side effects which are dose related, and in both cases using a lower dosage would still improve the efficacy and yet side effects would decrease. Secondly, the control of underlying metabolic syndrome promises true reversal of the diabetes pathophysiology, which is tied to Brake associated reversal of insulin resistance, hyperlipidemia, hyperglycemia, hypertension and central adiposity, all of which will be improved or resolved by including Brake in the combination therapy of diabetes patients with metabolic syndromes.
[0457] Combination therapy between metformin or sitagliptin (or both) and Brake for the surprising reversal of diabetes pathophysiology is hereby incorporated by reference to data disclosed herein, with daily dosages of Metformin of 500 mg per daily dose of Brake of 10-20 grams daily, both active agents are presented as micro granules for oral administration to patients with diabetes. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of diabetes to prevent the onset of metabolic syndrome associated damage to the pancreas, or at least delay its onset by many years. The disclosed combination product would be the first disease modifying treatment for this disease, here-to-fore considered to be irreversible.
[0458] Clinical proof of the utility of the synergistic combination of these diabetes therapies including Brake necessitate the regular measurement of biomarkers of metabolic syndrome progression such as the FS index, which is an overall biomarker profile that can point to regenerative processes that respond to RYGB or Brake. Added to the metabolic syndrome biomarker profile would be a biomarker profile of diabetes progression to CV injury. This latter progression profile would focus on cardiac injury, include epigenetics, metabolomics and genomics where applicable, and imaging where applicable to loss of cardiac structure and function. To the extent that these biomarkers are improved by metformin, those effects carry forward. To the extent that the observed improvement is tied to effects beyond those of metformin or sitagliptin, the conclusion would be Brake associated recovery or regeneration of pancreatic function.
Example 3. Obesity and Linkages to Intestinal Flora
[0459] Use of the disclosed treatments and methods of modifying human gastrointestinal flora for purposes of triggering regeneration of pancreatic beta cells, hepatic cells and regeneration of GI tract cells to benefit metabolic syndrome treatment are based on the findings incorporated by reference herein. The probiotic organisms chosen for over-coating in the formulation of the second active ingredient are Faecalibacterium prausnitzii, Bacteroides thetaiotaomicron, and Lactobacillus johnsonii. The approximate dose of these strains for release in the ileum according to the formulation is 10{circumflex over ()}6 to 10{circumflex over ()}8 colony forming units. It is anticipated that these specific organisms would be co-formulated with typical probiotic organisms such as lactobacilli and bifidobacterial.
[0460] Clinical proof of the utility of the synergistic combination of these diabetes therapies including Brake and probiotic replacement organisms would be provided by continued monitoring of biomarkers of metabolic syndrome progression, and the FS index would readily demonstrate the added benefit of combinations on regeneration. This effect is a newly discovered impact on the overall biomarker profile that can point to regenerative processes that respond to RYGB or Brake. Added to the metabolic syndrome biomarker profile of the FS index would be a biomarker profile of T2D progression to CV injury. This latter progression profile would focus on cardiac injury, include epigenetics, metabolomics and genomics where applicable, and imaging where applicable to loss of cardiac structure and function. To the extent that these biomarkers are improved by metformin, those effects carry forward. To the extent that the observed improvement is tied to effects beyond those of metformin or sitagliptin, the conclusion would be Brake or RYGB associated recovery or regeneration of pancreatic function, and a greater decline in the previously elevated FS index of said patient.
[0461] Grunfeld and colleagues connected intestinal flora. lipid absorption into chylomicrons endotoxin uptake and weight gain and insulin resistance in an editorial entitled Endotoxin in the gut and chylomicrons: translocation or transportation. This is a good review of current evidence for the premise of changing the intestinal flora in order to create a demand for a response by the immune system. Suppression of the immune response to absorbed fats and endotoxin leads to arteriosclerotic cardiovascular disease or ASCVD(39)
[0462] Recent data suggest that dietary fat promotes intestinal absorption of lipopolysaccharides (LPS) from the gut micro flora, which might contribute to various inflammatory disorders. The mechanism of fat-induced LPS absorption is unclear, however. Intestinal-epithelial cells can internalize LPS from the apical surface and transport LPS to the Golgi. The Golgi complex also contains newly formed chylomicrons, the lipoproteins that transport dietary long-chain fat through mesenteric lymph and blood. Because LPS has affinity for chylomicrons, these investigators hypothesized that chylomicron formation promotes LPS absorption. In agreement with their hypothesis, they found that CaCo-2 cells released more cell-associated LPS after incubation with oleic-acid (OA), a long-chain fatty acid that induces chylomicron formation, than with butyric acid (BA), a short-chain fatty acid that does not induce chylomicron formation. Moreover, the effect of OA was blocked by the inhibitor of chylomicron formation, Pluronic L-81. They also observed that intragastric triolein (TO) gavage was followed by increased plasma LPS, whereas gavage with tributyrin (TB), or TO plus Pluronic L-81, was not. Most intestinally absorbed LPS was present on chylomicron remnants (CM-R) in the blood. Chylomicron formation also promoted transport of LPS through mesenteric lymph nodes (MLN) and the production of TNFalpha mRNA in the MLN. Together, these data suggest that intestinal epithelial cells may release LPS on chylomicrons from cell-associated pools. Chylomicron-associated LPS may contribute to postprandial inflammatory responses or chronic diet-induced inflammation in chylomicron target tissues.(40)
[0463] Erridge and colleagues examined bacterial endotoxin, which is a potently inflammatory antigen that is abundant in the human gut(41). Endotoxin circulates at low concentrations in the blood of all healthy individuals, although elevated concentrations are associated with an increased risk of atherosclerosis. Erridge sought to determine whether a high-fat meal or smoking increases plasma endotoxin concentrations and whether such concentrations are of physiologic relevance. Plasma endotoxin and endotoxin neutralization capacity were measured for 4 h in 12 healthy men after no meal, 3 cigarettes, a high-fat meal, or a high-fat meal with 3 cigarettes by using the limulus assay. Baseline endotoxin concentrations were 8.2 pg/mL (interquartile range: 3.4-13.5 pg/mL) but increased significantly (P<0.05) by approximately 50% after a high-fat meal or after a high-fat meal with cigarettes but not after no meal or cigarettes alone. These results were validated by the observations that a high-fat meal with or without cigarettes, but not no meal or smoking, also significantly (P<0.05) reduced plasma endotox.in neutralization capacity, which is an indirect measure of endotoxin exposure. Human monocytes, but not aortic endothelial cells, were responsive to transient (30 s) or low-dose (10 pg/mL) exposure to endotoxin. However, plasma from whole blood treated with as little as 10 pg endotoxin/mL increased the endothelial cell expression of E-selectin, at least partly via tumor necrosis factor-alpha-induced cellular activation. Low-grade endotoxemia may contribute to the postprandial inflammatory state and could represent a novel potential contributor to endothelial activation and the development of atherosclerosis.(41)
[0464] T2D is associated with chronic low-grade inflammation, and adipose tissue (AT) may represent an important site of inflammation. 3T3-L1 studies have demonstrated that lipopolysaccharide (LPS) activates toll-like receptors (TLRs) to cause inflammation. For this study, we 1) examined activation of TLRs and adipocytokines by LPS in human abdominal subcutaneous (AbdSc) adipocytes, 2) examined blockade of NF-kB in human AbdSc adipocytes, 3) examined the innate immune pathway in AbdSc AT from lean, obese, and T2D subjects, and 4) examined the association of circulating LPS in T2D subjects. The findings showed that LPS increased TLR-2 protein expression twofold (P<0.05). Treatment of AbdSc adipocytes with LPS caused a significant increase in TNF-alpha and IL-6 secretion (IL-6, Control:2.7+/0.5 vs. LPS: 4.8+/0.3 ng/ml; P<0.001; 1NF-alpha, Control: 1.0+/0.83 vs. LPS: 32.8+/6.23 pg/ml; P<0.001). NF-kB inhibitor reduced IL-6 in AbdSc adipocytes (Control: 2.7+/0.5 vs. NF-kB inhibitor: 2.1+1-0.4 ng/ml; P<0.001). AbdSc AT protein expression for TLR-2, MyD88, TRAF6, and NF-kB was increased in T2D patients (P<0.05), and TLR-2, TRAF-6, and NF-kB were increased in LPS-treated adipocytes (P<0.05). Circulating LPS was 76% higher in T2D subjects compared with matched controls. LPS correlated with insulin in controls (r=0.678, P<0.0001). Rosiglitazone (RSG) significantly reduced both fasting serum insulin levels (reduced by 51%, P=0.0395) and serum LPS (reduced by 35%, P=0.0139) in a subgroup of previously untreated T2D patients. In summary, these results suggest that T2D is associated with increased endotoxemia, with AT able to initiate an innate immune response. Thus, increased adiposity may increase pro-inflammatory cytokines and therefore contribute to the pathogenic risk of T2D.(42)
[0465] RYGB results in profound weight loss and resolution of T2D. The mechanism of this remarkable transition remains poorly defined. It has been proposed that endotoxin (lipopolysaccharides [LPS]) sets inflammatory tone, triggers weight gain, and initiates T2D. Because RYGB may diminish LPS from endogenous and exogenous sources, we hypothesized that LPS and the associated cascade of oxidative and inflammatory stress would diminish after RYGB. Fifteen adults with morbid obesity and T2D undergoing RYGB were studied. After an overnight fast, a baseline blood sample was collected the morning of surgery and at 180 days to assess changes in glycemia, insulin resistance, LPS, mononuclear cell nuclear factor (NF)-kB binding and mRNA expression of CD14, TLR-2, TLR-4, and markers of inflammatory stress. At 180 days after RYGB, subjects bad a significant decrease in body mass index (52.1+/13.0 to 40.4+/11.1), plasma glucose (148+/8 to 101+/4 mg/dL), insulin (18.5+/2.2 mmuU/mL to 8.6+/1.0 mmuU/mL) and HOMA-IR (7.1+/1.1 to 2.1+/0.3). Plasma LPS significantly reduced by 20+/5% (0.567+/0.033 U/mL to 0.443+/0.022E U/mL). NF-kB DNA binding decreased significantly by 21+/8%, whereas TLR-4, TLR-2, and CD-14 expression decreased significantly by 25+/9%, 42+/8%, and 27+/10%, respectively. Inflammatory mediators CRP, MMP-9, and MCP-1decreased significantly by 47+/7% (10.7+/1.6 mg/L to 5.8+/1.0 mg/L), 15+/6% (492+/42 ng/mL to 356+/26 ng/mL) and 11+/4% (522+/35 ng/mL to 466+/35 ng/mL), respectively. CONCLUSION: LPS,NF-kB DNA binding, TLR-4, TLR-2, and CD14 expression, CRP, MMP-9, and MCP-1 decreased significantly after RYGB. The mechanism underlying resolution of insulin resistance and T2D after RYGB may be attributable, at least in part, to the reduction of endotoxemia and associated pro-inflammatory mediators.(43)
[0466] Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and the leading cause of chronic liver disease in the Western world. Twenty percent of NAFLD individuals develop chronic hepatic inflammation (non-alcoholic steatohepatitis, NASH) associated with cirrhosis, portal hypertension and hepatocellular carcinoma, yet the causes of progression from NAFLD to NASH remain obscure. Here, the investigators show that the NLRP6 and NLRP3 inflammasomes and the effector protein IL-18 negatively regulate NAFLD/NASH progression, as well as multiple aspects of metabolic syndrome via modulation of the gut microbiota. Different mouse models reveal that inflammasome-deficiency-associated changes in the configuration of the gut microbiota are associated with exacerbated hepatic steatosis and inflammation through influx of TLR4 and TLR9 agonists into the portal circulation, leading to enhanced hepatic tumor-necrosis factor (TNF)-alpha expression that drives NASH progression. Furthermore, co-housing of inflammasome-deficient mice with wild-type mice results in exacerbation of hepatic steatosis and obesity. Thus, altered interactions between the gut microbiota and the host, produced by defective NLRP3 and NLRP6 inflammasome sensing, may govern the rate of progression of multiple metabolic syndrome-associated abnormalities, highlighting the central role of the microbiota in the pathogenesis of heretofore seemingly unrelated systemic auto-inflammatory and metabolic disorders.(44)
[0467] As noted by Strowig, inflammasomes are a group of protein complexes built around several proteins, including NLRP3, NLRC4, AIM2 and NLRP6. Recognition of a diverse range of microbial, stress and damage signals by inflammasomes results in direct activation of caspase-1, which subsequently induces secretion of potent pro-inflammatory cytokines and a form of cell death called pyroptosis. Inflammasome-mediated processes are important during microbial infections and also in regulating both metabolic processes and mucosal immune responses. In the instant discussion, Strowig and colleagues review the functions of the different inflammasome complexes and discuss how aberrations in them are implicated in the pathogenesis of human diseases.(45)
[0468] Nearly a decade ago, the concept of inflammasomes was introduced. Since then, the biochemical characterization of the inflammasomes has led to a richer understanding of innate immune responses in the context of infection and sterile inflammation. This has provided the rationale for successful clinical therapies for a spectrum of hereditary periodic fever syndromes and potentially for some metabolic pathologies. (46)
[0469] Central adiposity is associated with metabolic alterations related to glucose homeostasis and cardiovascular risk factors. These metabolic alterations are associated with low-grade inflammation that contributes to the onset of these diseases. The authors provide evidence that gut microbiota participate in whole-body metabolism by affecting energy balance, glucose metabolism, and low-grade inflammation associated with central adiposity and related metabolic disorders. Recently, gut microbiota-derived lipopolysaccharide (LPS) (and metabolic endotoxemia) has been defined as a factor involved in the onset and progression of inflammation and metabolic diseases. In the review, the authors discuss mechanisms involved in the development of metabolic endotoxemia such as the gut permeability. The investigators also discuss these latest discoveries demonstrate a link between the gut microbiota, endocannabinoid system tone, leptin resistance, gut pepT1Des (glucagon-like peptide-1 and -2), and metabolic features. The authors also introduce the role of the gut microbiota in specific dietary treatments (prebiotics and probiotics) and surgical interventions (gastric bypass)(23)
[0470] The bridge between food intake and weight is not fully understood. Recently, the role of gut microbiota and bacterial lipopolysaccharides (LPS) in weight has been postulated. The objective for the study by Amar was to evaluate the relation between plasma LPS concentration and food intake. A dietary survey was conducted in 1015 subjects randomly recruited in France. The participants were given oral and written instructions on how to keep a consecutive 3 day food record. Plasma LPS was measured in a subsample of 201 men. In humans, no significant relation was observed between cardiovascular disease risk factors, carbohydrate and protein intakes, and plasma LPS concentration. Conversely, positive correlations were observed with fat and energy intakes. In a multivariate analysis, endotoxemia was independently associated with energy intake. In this large sample of healthy men from a population-based sample, Amar and colleagues found a link between food intake and plasma LPS. Experimental data suggest that fat was more efficient in transporting bacterial LPS from the gut lumen into the bloodstream. The results of this study add to the knowledge of mechanisms responsible for relations between food intake and metabolic diseases(47).
[0471] T2D and NAFLD are two metabolic diseases characterized by insulin resistance and a low-grade inflammation. Seeking an inflammatory factor causative of the onset of insulin resistance, hepatic steatosis, and T2D, we have identified bacterial lipopolysaccharide (LPS) as a triggering factor. The investigators found that normal endotoxemia increased or decreased during the fed or fasted state, respectively, on a nutritional basis and that a 4-week high-fat diet chronically increased plasma LPS concentration two to three times, a threshold that we have defined as metabolic endotoxemia. Importantly, a high-fat diet increased the proportion of an LPS-containing microbiota in the gut. When metabolic endotoxemia was induced for 4 weeks in mice through continuous subcutaneous infusion of LPS, fasted glycemia and insulinemia and whole-body, liver, and adipose tissue weight gain were increased to a similar extent as in high-fat-fed mice. In addition, adipose tissue F4/80-positive cells and markers of inflammation, and liver triglyceride content, were increased. Furthermore, liver, but not whole-body, insulin resistance was detected in LPS-infused mice. CD14 mutant mice resisted most of the LPS and high-fat diet-induced features of metabolic diseases. This new finding demonstrates that metabolic endotoxemia dysregulates the inflammatory tone and triggers body weight gain and T2D. The authors concluded that the LPS/CD14 system sets the tone of insulin sensitivity and the onset of T2D and NAFLD, and that lowering plasma LPS concentration could be a potent strategy for the control of metabolic diseases.(25)
[0472] T2D and obesity are characterized by a low-grade inflammation whose molecular origin is unknown. Cani and colleagues previously determined, first, that metabolic endotoxemia controls the inflammatory tone, body weight gain, and T2D, and second, that high-fat feeding modulates gut microbiota and the plasma concentration of lipopolysaccharide (LPS), i.e., metabolic endotoxemia. Therefore, it remained to demonstrate whether changes in gut microbiota control the occurrence of metabolic diseases. These researchers changed gut microbiota by means of antibiotic treatment to demonstrate, first, that changes in gut microbiota could be responsible for the control of metabolic endotoxemia, the low-grade inflammation, and T2D and, second, to provide some mechanisms responsible for such effect. They found that changes of gut microbiota induced by an antibiotic treatment reduced metabolic endotoxemia and the cecal content of LPS in both high-fat-fed and ob/ob mice. This effect was correlated with reduced glucose intolerance, body weight gain, fat mass development, lower inflammation, oxidative stress, and macrophage infiltration marker mRNA expression in visceral adipose tissue. Importantly, high-fat feeding strongly increased intestinal permeability and reduced the expression of genes coding for proteins of the tight junctions. Furthermore, the absence of CD14 in ob/ob CD14()(/)() mutant mice mimicked the metabolic and inflammatory effects of antibiotics. This new finding demonstrates that changes in gut microbiota controls metabolic endotoxemia, inflammation, and associated disorders by a mechanism that could increase intestinal permeability. It would thus be useful to develop strategies for changing gut microbiota to control, intestinal permeability, metabolic endotoxemia, and associated disorders.(21)
[0473] Central adiposity is now classically characterized by a cluster of several metabolic disorders, and by a low grade inflammation. The evidence that the gut microbiota composition can be different between healthy and or obese and type 2 diabetic patients has led to the study of this environmental factor as a key link between the pathophysiology of metabolic diseases and the gut microbiota. Several mechanisms are proposed linking events occurring in the colon and the regulation of energy metabolism, such as i.e. the energy harvest from the diet, the synthesis of gut pepT1Des involved in energy homeostasis (GLP-1, PYY . . . ), and the regulation of fat storage. Moreover, the development of central adiposity and metabolic disorders following a high-fat diet may be associated to the innate immune system. Indeed, high-sugar, high-fat dietary feeding triggers the development of obesity, inflammation, insulin resistance, T2D and atherosclerosis by mechanisms dependent of the LPS and/or the fatty acids activation of the CD14/TLR4 receptor complex. Importantly, fat feeding is also associated with the development of metabolic endotoxemia inhuman subjects and participates in the low-grade inflammation, a mechanism associated with the development of atherogenic markers. Finally, data obtained in experimental models and human subjects are in favor of the fact that changing the gut microbiota (with prebiotics and/or probiotics) may participate in the control of the development of metabolic diseases. The investigators opined that it would be useful to find specific strategies for modifying gut microbiota to impact metabolic diseases.(22)
[0474] Nowadays, the literature provides evidence that central adiposity, T2D and insulin resistance are characterized by a low grade inflammation. Among the environmental factors involved in such diseases, the gut microbiota has been proposed as a key player. This neglected organ has been found to be different between healthy and or obese and type 2 diabetic patients. For example, recent data have proposed that dysbiosis of gut microbiota (at phyla, genus, or species level) affects host metabolism and energy storage. Among the mechanisms, metabolic endotoxemia (higher plasma LPS levels), gut permeability and the modulation of gut pepT1Des (GLP-1 and GLP-2) have been proposed as putative targets. The authors postulate how gut microbiota can be involved in the development or in the control of central adiposity and associated low-grade inflammation. (26)
[0475] Obese and diabetic mice display enhanced intestinal permeability and metabolic endotoxemia that participate in the occurrence of metabolic disorders. Recent data support the idea that a selective increase of Bifidobacterium spp. reduces the impact of high-fat diet-induced metabolic endotoxemia and inflammatory disorders. Here, we hypothesized that prebiotic modulation of gut microbiota lowers intestinal permeability, by a mechanism involving glucagon-like peptide-2 (GLP-2) thereby improving inflammation and metabolic disorders during NAFLD and T2D. In the first study, ob/ob mice (Ob-CT) were treated with either prebiotic (Ob-Pre) or non-prebiotic carbohydrates as control (Ob-Cell). In order to assess the impact of GLP-2, Ob-CT and Ob-Pre mice were treated with GLP-2 antagonist or saline. Changes in the gut microbiota, intestinal permeability, gut peptides, intestinal epithelial tight-junction proteins ZO-1 and occludin (qPCR and immunohistochemistry), hepatic and systemic inflammation were all measured. Prebiotic-treated mice exhibited a lower plasma lipopolysaccharide (LPS) and cytokines, and a decreased hepatic expression of inflammatory and oxidative stress markers. This decreased inflammatory tone was associated with a lower intestinal permeability and improved tight-junction integrity compared to controls. Prebiotic increased the endogenous intestinotrophic proglucagon-derived peptide (GLP-2) production whereas the GLP-2 antagonist abolished most of the prebiotic effects. Finally, pharmacological GLP-2 treatment decreased gut permeability, systemic and hepatic inflammatory phenotype associated with metabolic syndrome to a similar extent as that observed following prebiotic-induced changes in gut microbiota. The authors found that a selective gut microbiota change controls and increases endogenous OLP-2 production, and consequently improves gut barrier functions by a GLP-2-dependent mechanism, contributing to the improvement of gut barrier functions during obesity and T2D.(24). This paper provides some background evidence why the ileal brake remodeling of the GI tract uses the GLP-2 pathway, and why the instant invention of Brake also increases the production of GLP-2 when used as directed.
[0476] Growing evidence supports the role of gut microbiota in the development of hepatic steatosis, T2D, and low-grade inflammation. The endocrine activity of adipose tissue has been found to contribute to the regulation of glucose homeostasis and low-grade inflammation. Among the key hormones produced by this tissue, apelin has been shown to regulate glucose homeostasis. Recently, it has been proposed that gut microbiota participate in adipose tissue metabolism via the endocannabinoid system (eCB) and gut microbiota-derived compounds, namely lipopolysaccharide (LPS). The authors have investigated gut microbiota composition in obese and diabetic leptin-resistant mice (db/db) by combining pyrosequencing and phylogenetic microarray analysis of 16S ribosomal RNA gene sequences. They observed a significant higher abundance of Firmicutes, Proteobacteria, and Fibrobacteres phyla in db/db mice compared to lean mice. The abundance of 10 genera was significantly affected by the genotype. They identified the roles of the eCB and LPS in the regulation of apelinergic system tone (apelin and APJ mRNA expression) in genetic obese and diabetic mice. By using in vivo and in vitro models, it was demonstrated that both the eCB and low-grade inflammation differentially regulate apelin and APJ mRNA expression in adipose tissue. Finally, deep-gut microbiota profiling revealed that the gut microbial community of type 2 diabetic mice is significantly different from that of their lean counterparts. This indicates specific relationships between the gut microbiota and the regulation of the apelinergic system. However, the exact roles of specific bacteria in shaping the phenotype of db/db mice remain to be determined.(48). The scientific linkage needed to complete these experiments was the ileal brake pathway, either by RYOB experiments or the use of Brake treatment.
[0477] Central adiposity is associated with accumulation of macrophages in white adipose tissue (WAT), which contribute to the development of insulin resistance. Germ-free (GF) mice have reduced adiposity and are protected against diet-induced central adiposity, To investigate whether the gut microbiota and, specifically, gut-derived lipopolysaccharide (LPS) promote WAT inflammation and contribute to impaired glucose metabolism. Macrophage composition and expression of pro-inflammatory and anti-inflammatory markers were compared in WAT of GF, conventionally raised and Escherichia coli-monocolonized mice. Additionally, glucose and insulin tolerance in these mice was determined. The presence of a gut microbiota resulted in impaired glucose metabolism and increased macrophage accumulation and polarization towards the pro-inflammatory M1 phenotype in WAT. Monocolonization of GF mice for 4 weeks with E. coli W3110 or the isogenic strain MLK1067 (which expresses LPS with reduced immunogenicity) resulted in impaired glucose and insulin tolerance and promoted M1 polarization of CD11b cells in WAT. However, colonization with E. coli W3110 but not MLK1067 promoted macrophage accumulation and up regulation of pro-inflammatory and anti-inflammatory gene expression as well as JNK phosphorylation. Conclusion Gut microbiota induced LPS-dependent macrophage accumulation in WAT, whereas impairment of systemic glucose metabolism was not dependent on LPS. These results indicate that macrophage accumulation in WAT does not always correlate with impaired glucose metabolism. (49)
[0478] It seems clear from the extensive studies of interactions between the human microbiome in the gut and the inflammation that follows dysbiotic changes in these flora, that a biomarker approach like the FS index can be relied upon to demonstrate favorable effects of RYGB surgery and/or Brake on L-cell signaling, provided that both the bacteria and the L-cells themselves are closely studied in health and disease. Based on the unexpected but highly beneficial improvement in biomarkers and improved beta cell functioning after RYGB, it is an aspect of the invention to treat early diabetes with a novel combination oral therapy of a diabetes drug, nominally for the first demonstration, metformin and Brake, and add to this a strategy to replace abnormal probiotic species with beneficial ones. Every patient would receive a Brake treatment combination regimen that would be demonstrated to be active on the basis of lowered biomarkers of diabetes in a pattern of elevation similar to that observed in our RYGB patients. In combination with oral Brake treatment as disclosed herein, the patient would also receive an approved front line treatment for T2D such as metformin, sitagliptin, or pioglitazone, any which could be given in the usual dose or, in many instances, at substantially lower dose than the typical dose given to patients. In fact, in some novel regimens, any of these could be given at half the usual dose or even less. The GI flora alterations and derangements that occur would be treated with replacement strains of the normal GJ tract formulation. There are two tested reasons why Brake would improve both the efficacy and safety of metformin or sitagliptin in the treatment of T2D, and why pancreatic beta cell recovery would be expected in this patient. First, both agents have side effects which are dose related, and in both cases using a lower dosage would still improve the efficacy and yet side effects would decrease. Secondly, the control of underlying metabolic syndrome promises true reversal of the diabetes pathophysiology, which is tied to revised flora in the GI tract as well as Brake associated reversal of insulin resistance, hyperlipidemia, hyperglycemia, hypertension and hepatic steatosis, all of which will be improved or resolved by including Brake in the combination therapy of T2D patients with metabolic syndromes.
[0479] Combination therapy between metformin or sitagliptin (or both) and Brake for the surprising reversal of T2D pathophysiology is hereby incorporated by reference, with dosages of Metformin of, for example, 250-500 mg per doses of Brake of 10-20 grams daily or less, both active agents are presented as micro granules for oral administration to patients with T2D. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of diabetes to prevent the onset of metabolic syndrome associated damage to the pancreas, or at least delay or inhibit its onset by many years. The disclosed combination product would be the first disease modifying treatment for this disease, here-to-fore considered to be irreversible.
Example 4. FS Index as a Measure of Regeneration in Response to Brake Treatment of Metabolic Syndrome
[0480] Use of the disclosed treatments and methods of modifying outcomes of metabolic syndromes by use of FS index are largely the work of the inventors.
[0481] Previously we disclosed the Supply/Demand index of cardiovascular risk for T2D treatments (see Monte US patent publication 2011/0097807, issued U.S. Pat. No. 8,367,418 and publications (2, 3)), said application being incorporated by reference herein, wherein we presented a T2D disease progression model that characterizes the effect of conventional antidiabetic therapies on the glucose supply and insulin demand dynamic that defines metabolic syndrome associated T2D, and links this SD index to cardiovascular risk specific to the treatment of T2D patients.
[0482] We have recently extended this concept from the T2D-centric HBA1c-SD parameter (2, 3) to create a global index of metabolic syndrome, termed here the FS (Fayad-Schentag) index, a quantitative means of describing progression of Metabolic Syndrome in Patients. The FS index is meant to track the beneficial changes in metabolic syndrome as it is managed by RYGB or by Brake, in turn a link to measurement of regeneration in the systems affected by the underlying common metabolic syndrome of these patients.
[0483] As underlying Metabolic Syndrome has many different manifestations in addition to those considered reflective of T2D, the FS index included hyperlipidemia, weight as BMI, triglycerides, liver enzymes specifically AST, hepatic steatosis and resulting NAFLD, in order to facilitate tracking progression of Metabolic Syndrome in patient populations that may have any or all of these conditions to varying degree. We now use tests for each component of Metabolic Syndrome. As a brief example why FS index is meaningful, it is known that anT1Diabetic drugs lower glucose but raise lipids or BP, and thus the net effect is to worsen the Metabolic Syndrome and increase CV risk. It was our hypothesis that improved risk scoring could be accomplished via an index that considered a composite of Metabolic Syndrome system components.
[0484] The FS index of Metabolic Syndrome is displayed in
[0485] In particular, the present invention generally proceeds when the steps in practice of the invention include testing the patient for laboratory biomarker patterns, use of the results of testing to calculate the FS index, determining the risk of organ damaging events from the FS index calculation (when the FS index measures at least about 60, 100, 150, 200, 300, 400 or 500 and above), the application of personalized treatment to lower the FS index, most preferably by the administration of a pharmaceutical composition targeted to a specific receptor (on the L-cells) in the distal intestine, in a dose and duration of treatment to lower the FS index of the patient upon repeat measurements. Ideally, the present invention can reduce a patient's FS index to the normal range (20-50).
[0486] The effect of the medicament on the measured biomarkers demonstrates beneficial properties of the ileal brake hormone releasing substance on the laboratory tests that comprise the FS index. In the ordinary assessment of the precise sequence of hormonally produced events, the patient experiences cessation of hunger. The patient benefits from the ileal brake hormone release with regeneration of organs and tissues, typically pancreas, liver and gastrointestinal tract and in certain instances, heart and vascular tissue.
[0487] With respect to the sequence of signaling molecules from the ileum, a response to the medicament entails a wake up stimulation of distal intestinal L-cells that have been quieted by actions of intestinal bacteria or metabolic disease; there is a release of hormones and signals from said L-cells; said released hormones traveling in portal blood to pancreas, liver and GI tract, said organs regenerated from available growth factors and hormone signals, measured biomarkers of the FS index demonstrating the successful regeneration and said regenerated organs then signaling the patient, preferably a human, to resume adequate nutrition seeking behavior as directed by restored signals of hunger.
[0488] High FS index values predicted CV risk in this patient population of patients, regardless of the specific components of Metabolic Syndrome that were abnormal. Abnormal and rising FS index values predicted AMI although did not predict the time of the event. A rapid rise in the FS index over 3-6 months was a good predictor of impending CV events. When Metabolic Syndrome is studied as the equal weight of its components using the FS index, it is apparent why clinical strategies treating only one component of Metabolic Syndrome do not remove all risk of CV events. The index also at least and partially explains why drug therapies that improve one aspect of Metabolic Syndrome, but worsen others, may not mitigate CV risk or remove CV events in complex Metabolic Syndrome patients. Abnormal FS index values subsequently normalized, indicated resolution of each component of Metabolic Syndrome, raising the possibility that specific treatments of Metabolic Syndrome might halt progression or reverse Metabolic Syndrome entirely. For example, changes in FS index in patients with RYGB surgery were dramatic, taking scores of these patients from above 250 to values below 20 in most cases. Responses to oral Brake were similar to RYGB, even though Brake treated patients did not lose as much weight. These data were provided earlier in this application.
[0489]

[0493] The final model for implementing this metabolic syndrome CV progression model is an application for individual patients on a computer such as a web-enabled cellphone, an iPad or a Windows 8 tablet. The application will record weight, food intake, calories from specific type of food, and exercise. From these, each patient's insulin output and CV risk is calculated daily and the metabolic syndrome progression is linked to food and lifestyle. Once the links are established for each patient, the application puts the patient onto an optimization plan that should minimize disease and maximize life expectancy. An example of a weight reduction tracked on said application for one patient is
[0494] Weight is plotted in as shown in
[0495] Overall, the FS(Fayad/Schentag) index, which is composed of mostly readily available laboratory and clinical measures, appears to be a promising means of describing progression or amelioration of the end organ manifestations of metabolic syndromes in routine practice, including the changes that occur as a result of organ or system regeneration after RYGB surgery or treatment with Brake. Its use in aggregate or use of its principle components separately are hereby designated as a primary means of demonstrating direction of metabolic syndrome manifestations (improved or worsening) and the impact of therapeutic interventions designed to improve metabolic syndrome via stop and repair mechanisms of action. To avoid doubt, said therapeutic interventions include both RYGB and combinations of pharmaceuticals wherein the composition of said pharmaceuticals includes Brake or its specific components in a dosage range between 2500 mg and 20000 mg, often about 5000 to 12,500 mg, more often about 7500-10,000 mg.
Example 5. Reversal of Atherosclerosis and Cardiac Disease
[0496] Statins are the mainstay treatment for atherosclerosis and all statins show a dose related lowering of hyperlipidemia. Some strains have shown a reduction in cardiovascular risk profile. This may be achieved by lipid lowering or it may be result of reduced inflammation or both. Statins alone are not known to regenerate the cardiovascular system or the vascular endothelium. RYGB surgery on the other band, has a modest lowering of cholesterol, but a dramatic evidence of organ and tissue regeneration, including in the heart and blood vessels. One aspect of the greater effect of RYGB surgery is its impact across the dietary supply side pathways of sugar and fat, T2D and hyperlipidemia. Evidence favoring the combination approach of an orally active RYGB mimetic with a statin is provided below. Subsequently, the inventors disclose our own findings demonstrating the synergistic effects of the combination product of controlled release Brake over-coated with 10 mg of a statin. An alternative pharmaceutical agent for over-coating is 10 mg of lisinopril or a suitable ACE inhibitor or AII inhibitor.
[0497] The pharmaceutical composition orally active on the ileal brake as disclosed herein may be over-coated with one or more statins in a weight ratio of approximately 0.001 parts atorvastatin or its equivalent potency to each 1.0 part refined sugar or approximately 0.005 part statin:1.0 part refined sugar (e.g. statins selected from the group consisting of atorvastatin, simvastatin, pravastatin, rosuvastatin, lovastatin, fluvastatin and pitavastatin); the enteric coated core of the pharmaceutical composition may also comprise approximately 60-80% refined sugar, 0-40% of a plant-derived lipid and 0-40% of a plant-derived lipid; and/or when apportioning the daily dose of lisinopril onto the daily dose of ileal brake hormone releasing substance in the enteric coated tablet form, the 1.0 gram tablets are over-coated with the immediate release lisinopril in a weight ratio of approximately 0.0005 to 0.002 parts lisinopril to each 1.0 part refined sugar (e.g. ACE inhibitors selected from the group consisting of lisinopril, enalapril, ramipril, perindopril, quinapril, and e.g., any of the AII inhibitors selected from the group consisting of losartan, olmesartan, valsartan, all at dosage equivalents to lisinopril).
[0498] Some examples of patients treated with atorvastatin and Brake together, but as separate pills are presented in
[0499] Yu and colleagues examined the effects of early treatment with pravastatin on the progression of glucose intolerance and cardiovascular remodeling in a model of spontaneously developing T2D, the Otsuka Long-Evans Tokushima Fatty (OLETF) rats. The OLETF rats were treated with pravastatin (100 mg/kg/day) from 5 weeks of age and compared with age-matched untreated OLETF rats and normal Long-Evans Tokushima Otsuka (LETO) rats on serial oral glucose tolerance tests (OGTT) and Doppler echocardiography and on histopathological/biochemical analyses of the heart at 30 weeks. The OGTT revealed that 40% and 89% of untreated OLETF rats were diabetic at 20 and 30 weeks, respectively, but 0% and only 30%, respectively, were diabetic in the treated OLETF. Left ventricular diastolic function was found impaired from 20 weeks in untreated OLETF but remained normal in the treated-OLETF. The wall-to-lumen ratio and perivascular fibrosis of coronary arteries were increased in untreated-OLETF but were limited in the treated-OLETF at 30 weeks. Moreover, cardiac expressions of a fibrogenic growth factor, transforming growth factor-beta1 (TGF-beta1), and a pro-inflammatory chemokine, monocyte chemoattractant protein-1 (MCP-1), were increased in untreated-OLETF. However, in the treated-OLETF, over-expressions of TGF-beta1 and MCP-1 were attenuated, which was associated with overexpression of endothelial nitric oxide synthase (eNOS) (2.5-fold of control LETO). Early pravastatin treatment prevented cardiovascular remodeling in the spontaneous DM model by retarding the progression of glucose intolerance, overexpressing cardiac eNOS, and inhibiting over expressions of fibrogenic/pro-inflammatory cytokines.(50). Clearly any of these effects would be synergistic with Brake associated regeneration of pancreas and liver.
[0500] Infection and inflammation induce the acute-phase response, leading to multiple alterations in lipid and lipoprotein metabolism. Plasma triglyceride levels increase from increased VLDL secretion as a result of adipose tissue lipolysis, increased de novo hepatic fatty acid synthesis and suppression of fatty acid oxidation. With more severe infection, VLDL clearance decreases secondary to decreased lipoprotein lipase and apolipoprotein E in VLDL. In rodents, hypercholesterolemia occurs attributable to increased hepatic cholesterol synthesis and decreased LDL clearance, conversion of cholesterol to bile acids, and secretion of cholesterol into the bile. Marked alterations in proteins important in HDL metabolism lead to decreased reverse cholesterol transport and increased cholesterol delivery to immune cells. Oxidation of LDL and VLDL increases, whereas HDL becomes a pro-inflammatory molecule. Lipoproteins become enriched in ceramide, glucosylceramide, and sphingomyelin, enhancing uptake by macrophages. Thus, many of the changes in lipoproteins are pro-atherogenic. The molecular mechanisms underlying the decrease in many of the proteins during the acute phase reaction involve coordinated decreases in several nuclear hormone receptors, including peroxisome proliferator-activated receptor, liver X receptor, farnesoid X receptor, and retinoid X receptor. Acute phase response-induced alterations initially protect the host from the harmful effects of bacteria, viruses, and parasites. However, if prolonged, these changes in the structure and function of lipoproteins will contribute to atherogenesis.(51). These pathways are thought to lead to an increased risk in T2D for Cardiovascular events like Myocardial infarction and stroke, and it has recently been shown that obese children already have these findings, predicting risk for early atherosclerosis even in childhood(52).
[0501] By way of specific examples of diet associated ASCVD, Shai and colleagues studied the role of dietary intervention in the reversal of atberosclerosis. In a 2-year Dietary Intervention Randomized Controlled Trial-Carotid (DIRECT-Carotid) study, participants were randomized to low-fat, Mediterranean, or low-carbohydrate diets and were followed for changes in carotid artery intima-media thickness, measured with standard B-mode ultrasound, and carotid vessel wall volume (VWV), measured with carotid 3D ultrasound. They found that 2 year weight loss diets can induce a significant regression of measurable carotid VWV. The effect was similar in low-fat, Mediterranean, or low-carbohydrate strategies and appears to be mediated mainly by the weight loss-induced decline in blood pressure(53). Clearly dietary effects of Brake are important to reduce the load of sugar and fat on the atherogenic pathways of the body.
[0502] These pathways have been associated with progressive accumulation of sugars and fats. There have been clinical studies strongly suggesting that so-called hyperglycemic memory which is actually a persisting cumulative record of diabetic damage, cap. show evidence of chronic abnormalities in diabetic blood vessels that are not easily reversed, even by subsequent, relatively good control of blood glucose. Among various biochemical pathways implicated in diabetic vascular complications, the process of formation and accumulation of advanced glycation end products (AGEs) and their mode of action are most compatible with the theory hyperglycemic memory. The review by Yamagishi and colleagues discusses the role of AGEs in thrombogenic abnormalities in T2D, especially focusing on the deleterious effects of these macroproteins on endothelial cell function, platelet activation and aggregation, coagulation and fibrinolytic systems(54).
[0503] The core areas for regeneration in atherosclerosis are the endovascular walls, and here the damage is accelerated by the combined adverse forces of inflammation, lipid accumulation, tear and repair from hypertension, and micro coagulopathy. Accordingly, vascular improvements may be logically made with lowering of each of these processes, but it does not necessarily follow that lowering any one of them is going to reverse the damage and regenerate endovascular lining. It does appear certain that all of these processes are improved simultaneously by RYGB surgery, as detailed by several authors and summarized below.
[0504] It also follows that drugs used in combination with Brake for regeneration of endovascular walls would come from the following 4 classes of agents, each of which can be combined with Brake for a comprehensive endovascular remodeling and regeneration program for the patients in need. These concomitant drugs, termed second active agents and over-coated onto the Brake tablets are as follows:
[0505] HMG-CoA reductase inhibitors, also called statins, of which the preferred embodiment is Atorvastatin (Lipitor) in a low dose of 10 mg, or any statin in an equivalent amount, chosen from the alternative listing: Fluvastatin (Lescol), Lovastatin (Mevacor), Pitavastatin (Livalo), Pravastatin (Pravachol), Rosuvastatin (Crestor), Simvastatin (Zocor), among other possible statins.
[0506] Angiotensin Converting Enzyme (ACE) inhibitors with preferred example a 10 mg daily dose of Lisinopril (Prinivil, Zestril) or a suitable alternative in an equivalent amount chosen from those marketed ACE inhibitors: benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), moexipril (Univasc), perindopril (ceon), quinapril (Accupril), ramipril (Altace), trandolapril (Mavik). among other possible alternative ACE inhibitors.
[0507] Angiotensin II inhibitors with preferred example an 80 mg dose of Losartan or an equivalent amount of alternative Angiotensin II inhibitor including but not limited to candesartan, irbesartan, valsartan, olmesartan, Telmisartan, among other possible Angiotensin II inhibitors.
[0508] Beta Blockers with preferred example propranolol (Inderal) in a dose of 20 mg or a suitable alternative in an equivalent amount chosen from the list of beta blockers: acebutolol (Sectral); atenolol (Tenormin); betaxolol (Kerlone); bisoprolol (Zebeta); carteolol (Cartrol); esmolol (Brevibloc); metoprolol (Lopressor); penbutolol (Levatol); nadolol (Corgard); nebivolol (Bystolic); pindolol (Visken); timolol (Blocadren); sotalol (Betapace); carvedilol (Coreg); labetalol (Trandate), among other possible beta blockers.
[0509] Having described these combination products including Brake, what can be expected when they are used together to regenerate the endovascular cells and the heart itself? The most crucial point of information is the reversal caused by RYGB surgery, as described below:
[0510] Several studies point to the reversal of Atherosclerosis by RYGB. On a mechanistic note, Illan-Gomez evaluated the relationships between inflammation and atherosclerosis by examining patients for changes in the pro-inflammatory profile of morbidly obese patients after weight loss following bariatric surgery (55). They measured levels of adiponectin, high-sensitivity C-reactive protein (hsCRP), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) and their relation to insulin resistance and lipid parameters in 60 morbidly obese women at baseline and 3, 6 and 12 months after gastric bypass. Twelve months after RYGB surgery, there was a significant increase in plasma levels of adiponectin (p<0.001) and high-density lipoprotein cholesterol (p<0.01) and a significant decrease in levels of IL-6 (p<0.001), hsCRP (p<0.001), cholesterol (p<0.001), triglycerides (p<0.001), low-density lipoprotein cholesterol (p<0.001), glucose (p<0.001), insulin (p<0.001) and homeostasis model assessment (HOMA; p<0.001). At 12 months, correlations were seen between IL-6 levels and the following: body mass index (BMI) (r=0.53, p<0.001), insulin (r=0.51, p<0.001) and HOMA (r=0.55, p<0.001). Also, hsCRP levels correlated with BMI (r=0.40, p=0.004), triglycerides (r=0.34, p=0.017), insulin (r=0.50, p=0.001) and HOMA (r=0.46, p=0.002). In patients with morbid obesity, significant weight loss is followed by a significant improvement in the inflammatory state, insulin sensitivity and lipid profile. A relationship exists between improved inflammatory profile and lowered insulin resistance(55).
[0511] The long term outcomes of the RYGB patients with similar changes in inflammation and lipid parameters have been studied by several groups and will be summarized below.
[0512] The objective of Owan and colleagues was to test the hypothesis that RYGB would favorably impact cardiac remodeling and function, which would demonstrate beneficial actions beyond the reversal of atherosclerosis alone. Owan and Colleagues prospectively studied 423 severely obese patients undergoing RYGB and a reference group of severely obese subjects that did not have surgery (n=733). At a 2-year follow up, RYGB subjects had a large reduction in BMI compared with the reference group, and significant reductions in waist circumference, systolic blood pressure, heart rate, triglycerides, low-density lipoprotein cholesterol, and insulin resistance. High-density lipoprotein cholesterol increased. The RYGB group had reductions in left ventricular (LV) mass index and right ventricular (RV) cavity area. Left atrial volume did not change in RYGB but increased in reference subjects. In conjunction with reduced chamber sizes, RYGB subjects also had increased LV midwall fractional shortening and RV fractional area change. In multivariable analysis, age, change in body mass index, severity of nocturnal hypoxemia, E/E, and sex were independently associated with LV mass index, whereas surgical status, change in waist circumference, and change in insulin resistance were not. They concluded that the RYGB patients had evidence of cardiac remodeling and improved LV and RV function. These data supported the use of RYGB to prevent cardiovascular complications in severe obesity.(56). The data also predict similar outcomes as these patients are treated with Brake
[0513] The diagnosis of the metabolic syndrome (MS) appears to identify substantial. additional cardiovascular risk above and beyond the individual risk factors, even though the pathophysiology underlying this evidence is still incompletely understood. The inflammatory response related to fat accumulation may influence cardiovascular risk through its involvement not only in body weight homeostasis, but also in coagulation, fibrinolysis, endothelial dysfunction, insulin resistance and atherosclerosis. Moreover, there is evidence that oxidative stress may be a mechanistic link between several components of MS and CVD, through its role in inflammation and its ability to disrupt insulin-signaling. The cross-talk between impaired insulin-signaling and inflammatory pathways enhances both metabolic IR and endothelial dysfunction which synergize to predispose to CVD. Persistent platelet hyper-reactivity/activation emerges as the final pathway driven by intertwined interactions among insulin resistance, adipokine release, inflammation, dyslipidemia and oxidative stress and provides a pathophysiological explanation for the excess risk of atherothrombosis in this setting. Despite the availability of multiple interventions to counteract these metabolic changes, including appropriate diet, regular exercise, anti-obesity drugs and bariatric surgery, relative failure to control the incidence of metabolic syndrome and its complications reflects both the multi factorial nature of these diseases as well as the scarce compliance of patients to established strategies. Evaluation of the impact of these therapeutic strategies on the pathobiology of atherothrombosis, as discussed in this review, will translate into an optimized approach for cardiovascular prevention.(57). These authors are clearly validating the instant invention, since the use of Brake in combination with the available front line therapy will manage all of the protean manifestations of metabolic syndrome via activation of the ileal brake pathway.
[0514] Metabolic syndrome is commonly associated with multiple conditions imparting adverse cardiovascular risk, including hypertension, dyslipidemia, insulin resistance and T2D. In addition, sleep disordered breathing, inflammation, left ventricular hypertrophy, left atrial enlargement, and subclinical left ventricular systolic and diastolic dysfunction may collectively contribute to increased cardiovascular morbidity and mortality. This review describes improvements in cardiovascular risk factors after bariatric surgery. All of the cardiovascular risk factors listed above are improved or even resolved after RYGB surgery. Cardiac structure and function also have shown consistent improvement after surgically induced weight loss. The amount of improvement in cardiac risk factors is generally proportional to the amount of weight lost. The degree of weight loss varies with different bariatric procedures. On the basis of the improvement in risk profiles, it has been predicted that progression of atherosclerosis could be slowed and the 10-year risk of cardiac events would decline by 50% in patients undergoing weight loss surgery. In keeping with these predictions, two studies have demonstrated reductions in 10-year total and cardiovascular mortality of approximately 50% in patients who had bariatric surgery. These encouraging data support the continued, and perhaps expanded, use of surgical procedures to induce weight loss in severely obese patients.(58). Clearly the reversal of the CV and metabolic syndrome biomarkers shown in RYGB patients is only possible with regeneration pathways activated by the ileal brake hormones that are released in these patients (
[0515] Best and Colleagues considered the CV risk profile of conventional T2D drug therapy in relation to incretin therapies like exenatide. A retrospective database analysis was performed of the Life Link database of medical and pharmaceutical insurance claims for June 2005 through March 2009. Patient outcomes were adjusted for differences in clinical and demographic characteristics and compared using propensity score-weighted discrete time survival analysis with time-varying exposure to exenatide. A total of 39,275 patients with T2D treated with exenatide twice daily, and 381,218 patients were treated with other glucose-lowering therapies. Patients who initiated exenatide were more likely to have prior ischemic heart disease, hyperlipidemia, hypertension, and/or other comorbidities at baseline. Exenatide-treated patients were less likely to have a CVD event than non-exenaT1De-treated patients (hazard ratio 0.81; 95% CI 0.68-0.95; P=0.01) and lower rates of CVD-related hospitalization (0.88; 0.79-0.98; P=0.02) and all-cause hospitalization (0.94; 0.91-0.97; P<0.001). Exenatide twice-daily treatment was associated with a lower risk of CVD events and hospitalizations than treatment with other glucose-lowering therapies, supporting a lower risk profile associated with the beneficial hormones of the ileal brake (59). The better decline in FS index shown herein supports this conclusion, and favors the use of Brake treatment for patients with metabolic syndrome in its various manifestations.
[0516] Clearly, RYGB effects as mediated by the ileal brake are beneficial on both atherosclerosis and cardiac functional markers. As with other affected organs that are targets of metabolic syndrome, there is plenty of evidence that RYGB reverses at least a proportion of the injury to the end organ, presumably mediated by the hormones elicited from the L cells of the distal intestine and ileal brake. It would be expected that treatment with Brake, as an oral mimetic of the RYGB effects on the ileal Brake, would also be able to demonstrate reversal of atherosclerosis and myocardial injury to a similar degree over a similar time frame, so long as the hormonal responses are similar between RYGB patients and Brake treated patients. Data presented herein say that they are.
[0517] The notable reversal of CV disease risk following RYGB surgery has been associated with resolution of elevated triglycerides, elevation of HDL, lowering of LDL, and lowering of hepatic inflammation, as was seen using the FS index to monitor the course of these parameters in our patients with RYGB (43) and shown in
[0518] Combination therapy between a statin and Brake for the surprising reversal of atherosclerosis is hereby incorporated by reference, with dosages of Simvastatin, Atorvastatin of 10-20 mg per dose of Brake of 10-20 grams daily, both active agents are presented as micro granules for oral administration to patients with atherosclerosis, or alternatively as the immediate release form of atorvastatin over-coated onto the tablets of Brake. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of hyperlipidemia to prevent the onset of metabolic syndrome associated damage to the heart and CV system, or at least delay its onset by many years. The disclosed combination product would be the first disease modifying treatment for this disease, here-to-fore considered to be progressive and irreversible.
[0519] Clinical proof of the utility of the synergistic combination of these atherosclerosis reversal therapies including Brake would necessitate the adoption of biomarkers of metabolic syndrome progression such as the FS index, which is an overall biomarker profile that can point to regenerative processes that respond to RYGB or Brake. Added to the metabolic syndrome biomarker profile of the FS index would be a biomarker profile of T2D progression to CV injury. This latter progression profile would focus on cardiac injury, include epigenetics, metabolomics and genomics where applicable, and imaging where applicable to loss of cardiac structure and function. To the extent that these biomarkers are improved by statins, those effects carry forward as supportive evidence in the cholesterol pathway itself. To the extent that the observed improvement is tied to effects beyond those of atorvastatin or simvastatin, the conclusion would be Brake. associated recovery or regeneration of cardiac function.
[0520] Every patient would receive Brake treatment that would be demonstrated to be active on the basis of lowered biomarkers of ASCVD in a pattern of elevation similar to that observed.in our RYGB patients. In combination with oral Brake treatment as disclosed herein, the patient would also receive an approved front line treatment for hyperlipidemia such as simvastatin or atorvastatin or other statin, for example the immediate release forms of either of these therapeutics over-coated onto the ileal brake hormone releasing composition Brake. Atorvastatin when given in this manner is so active in the composition that the atorvastatin dose is a low dose 10 mg per 24 hours, which is nearly the lowest dosage used and is clearly free of the risk of statin side effects such as myopathy. There are two tested reasons that Brake would improve both the efficacy and safety of statins in the treatment of T2D. First, both agents have side effects which are dose related, and in both cases using a lower dosage would still improve the efficacy and yet side effects would decrease. Secondly, the control of underlying metabolic syndrome offers the previously unexpected reversal of the atherosclerosis pathophysiology, which is tied to Brake associated reversal of insulin resistance, hyperlipidemia, hyperglycemia, hypertension and hepatic steatosis, .all of which will be improved or resolved by including Brake in the combination therapy of atherosclerosis patients with metabolic syndromes.
[0521] Brake therapy is likely to be synergistic with acyl-coenzyme A: cholesterol O-acyltransferase (ACAT) inhibitors, which are important in the generation of lipid-filled monocytes-macrophages. In attest of this hypothesis, the ACAT inhibitor CI-976 (2,2-dimethyl-N-(2,4,6-trimethoxyphenyl) dodecanamide) was evaluated relative to selected lipid-lowering agents for their effect on atherosclerotic lesion regression and progression. Atherosclerotic lesions comparable in composition to human fatty streaks were induced by chronic endothelial denudation in the iliac-femoral artery of hypercholesterolemic New Zealand White rabbits before intervention, while naturally occurring fatty streaks developed in the thoracic aorta. CI-976 administered in a hypercholesterolemic diet at a dose that did not lower plasma cholesterol prevented the accumulation of monocytes-macrophages within the pre-established iliac-femoral lesion and reduced the foam cell area by 27-29% relative to the initiation of intervention. CI-976 also blunted the development of thoracic aortic fatty streak-like lesions and decreased the cholesteryl ester enrichment by 46%. CI-976 had no effect on plasma triglycerides and, more importantly, had no effect or decreased liver, iliac-femoral, and thoracic aorticfreecholesterol content. Dietary intervention alone increased monocyte-macrophage involvement in the iliac-femoral lesion despite reductions in plasma, liver, and thoracic aortic cholesterol content. Conventional lipid-lowering therapy such as cholestyramine or cholestyramine/niacin required substantial decreases in plasma cholesterol levels to achieve comparable vascular changes. These authors conclude that inhibition of ACAT within the arterial wall by the potent and specific ACAT inhibitor CI-976, even in the absence of plasma cholesterol lowering, can result in the inhibition of atherosclerotic lesion progression and can enhance regression(60)
[0522] We believe these data support the thesis of Shai (53) and demonstrate evidence of reversal of atherosclerosis associated damage.
[0523] There are some additional compounds that would be useful in combination with oral mimetics of RYGB that release ileal brake hormones as their primary mechanism of action. The following agents would synergistically combine with Brake to regenerate endovascular surfaces and thereby mitigate atherosclerosis and lessen the numbers of patients who progress to ASCVD.
[0524] One example is ETC-216. Recently, regression of atherosclerosis was achieved in coronary patients by repeated infusions of ETC-216. Thirty-six rabbits underwent perivascular injury at both caroT1D arteries, followed by a 1.5% cholesterol diet. After 90 days, rabbits were randomly divided into 6 groups and treated 5 times with vehicle or ETC-216 at 5, 10, 20, 40, or 150 mg/kg dose every 4 days. Carotid plaque changes were evaluated in vivo by intravascular ultrasound (IVUS) and magnetic resonance imaging (MRI), performed before and at the end of treatments. Magnetic resonance imaging scans were also recorded after administration of the second dose for rabbits infused with vehicle 40 or 150 mg/kg. Atheroma volume in vehicle-treated rabbits increased dramatically between the first and the second IVUS analyses (+26.53%), whereas in ETC-216-treated animals, a reduced progression at the lower doses and a significant regression at the higher doses, up to 6.83%, was detected. Results obtained by MRI analysis correlated significantly with those at IVUS (r=0.706; p<0.000 1). The MRI evaluations after the second infusion established that a significant regression was achieved with only 2 administrations of the highest dose. These results confirm the efficacy of ETC-216 for atherosclerosis treatment and provide guidance for dose selection and frequency to obtain a significant reduction of plaque volume.(61)
[0525] RVX-208 is a first-in-class small molecule that inhibits BET bromodomains. RVX-208 functions by removing atherosclerotic plaque via reverse cholesterol transport (RCT), the natural process through which atherosclerotic plaque is transported out of the arteries and removed from the body by the liver. RVX-208 increases production of Apolipoprotein A-I (ApoA-I), the key building block of functional high-density lipoprotein (HDL) particles and the type required for RCT. These newly produced, functional HDL particles are flat and empty and can efficiently remove plaque and stabilize or reverse atherosclerotic disease. Results from the ongoing analysis of its Phase 2b ASSURE clinical trial using intravascular ultrasound (IVUS) to study high-risk cardiovascular disease (CVD) patients for assessing benefits of RVX-208 show statistically significant improvements in coronary IVUS atheroma measurements and Major Adverse Cardiac Events (MACE) in patients with a high (>2.0 mg/dL) serum high sensitivity C-Reactive Protein (hsCRP). Serum levels of this biomarker when>2.0 mg/dL reflect a heightened state of inflammation that is a well-known and major component of CVD risk. Patients with hsCRP>2.0 mg/dL at time of entry into ASSURE totaled n=184 of which n=54 were given placebo while n=130 received RVX-208. In theRVX-208 treated patients, the incidence of MACE was lower by 63% (p=0.023) vs. placebo. The preceding observation is of value in that hsCRP of >2.0 mg/dL is well known to be clinically important in predicting CVD risk.
[0526] The VH-IVUS data was analyzed to provide insight into vulnerability of an atherosclerotic plaque to rupture and its relationship to future cardiovascular risk. In ASSURE, while all (n=323) patients were studied using IVUS, 87 of these were examined using the Volcano Revolution catheter to gather VH-IVUS information. This information was used to reflect plaque vulnerability by calculating the ratio of necrotic core to dense calcium (NC/DC) as established by Missel et al. (Am J Cardiol 2008; NC/DC ratio). The NC/DC ratio in RVX-208 treated patients (n=61) was significantly lower by 7.5%. The treatment of ASSURE patients with low HDL-C given rosuvastatin further defined a large high risk population where RVX-208 illustrates profound effects to reduce atheroma volume and plaque vulnerability. Together these findings help explain the observed reduction in MACE events.
[0527] RVX-208 is given in doses of 100 mg once daily, and could be readily over-coated onto 7 Brake pills for a complete lipid control regimen, which would reverse atherosclerosis and be cardio protective of MACE events in patients receiving statins.
[0528] In another aspect of the present invention, there are compounds suitable to combine with the ileal brake hormone releasing substance of the invention, wherein the patient with congestive heart failure (CHF) could greatly benefit from cardiovascular system regeneration. One example is the alpha-beta blocker agent carvedilol, which itself has been beneficial to patients with CHF. In the preferred embodiment of the combination product, the desired dose of carvedilol could be lowered to 12.5 mg every 24 hrs and still be effective in CHF.
Example 6. Hepatic Regeneration
[0529] Some examples of patients treated with atorvastatin and Brake together, but as separate pills are presented in
[0530] In another preferred embodiment, the use of Brake in combination with antiviral compounds is disclosed for the treatment of Hepatic steatosis associated with hepatitis B and C. In this application, the disclosed medicaments in combination regenerate the damaged liver itself, which resolves inflammation and conveys a lowering of hepatic enzymes. In general, as AST falls to normal, the damaged liver has been at least partially regenerated. One additional benefit is the lowering of alpha-fetoprotein, which is a marker of risk for hepatocellular carcinoma. An example of hepatic steatosis resolution in a 36 year old male with hepatitis C, our patient, E2. Initially his weight was 1851b, with a calculated BMI of 29. His Hepatitis C was genotype 1a TC, and when he presented his liver biopsy showed hepatic steatosis and 1/4 fibrosis. He was started on interferon and ribavirin, but these agents did not control the viral load. Accordingly, Brake was added to his regimen and continued for 24 months. Viral load became undetectable, hepatic enzymes and triglycerides normalized. In
[0531] In a further practice of the invention, berberine in available forms in a daily amount of 500-1000 mg may be substituted for a statin and be likewise over-coated in the combination formulation.
[0532] Berberine is an alkaloid that has been isolated from various anti-diabetic plants used in Traditional Chinese Medicine. Berberine has various mechanisms of action, but tends to be known as an AMPK activator; alongside AMPK activation, berberine also exerts anti-inflammatory effects, benefits to intestinal health and integrity, possible synergism with anti-depressant medications, lipid and cholesterol lowering effects, and strong anti-diabetic effects. The anti-diabetic effects of berberine are the most well-researched, and are partly due to AMPK activation; PTP1B inhibition, which reduces glucose production in the liver, may also contribute, as well as berberines anti-inflammatory effects. Comparative research in both animals and humans (as well as one meta-analysis on humans) demonstrate that the anti-diabetic effects of 1500 mg of Berberine taken in three doses of 500 mg appear to be equal to those of 1500 mg Metformin or 4 mg Glibenclamide in terms of reducing biomarkers of type 2 diabetes.
[0533] Additionally due to the mechanism of action being AMPK activation, berberine exhibits fairly potent lipid-lowering effects, and via other unrelated mechanisms also reduces circulating cholesterol levels; these side effects make berberine desirable for reducing the risk of cardiac complications associated with diabetes. There are also some less-proven but promising effects associated with berberine supplementation that may protect against diabetic cardiomyopathy and diabetic nephropathy.
[0534] Release of ileal brake hormones increases hepatic cell mass and decreases the number of inflamed hepatic cells in the Hepatic Steatosis patient and typically and uniquely normalizes triglycerides, hepatic enzymes, alpha-fetoprotein and cholesterol. As further demonstration of heretofore unexpected hepatocellular regeneration, the effects of daily use of the dosage form for 6 months persist for prolonged periods even if the medication is not taken.
[0535] Use of the disclosed treatments and methods of modifying L-cell output of regulatory hormones for purposes of triggering regeneration of pancreatic beta cells, hepatic cells and regeneration of GI tract cells, is advised in order to benefit patients having metabolic syndrome and in need of improved organ function, the changes from which treatment are long lasting and universally beneficial.
[0536] Insulin resistance is a key component of the metabolic syndrome (MS) and is strongly associated with liver steatosis. None of the current treatments for metabolic syndrome resolve Insulin resistance, yet resolution of insulin resistance is necessary to effect a regeneration of peripheral systems such as neural tissue or indeed the heart and brain. One clear benefit is to start regeneration early, for example in childhood obesity.
[0537] The aim of D'Adamo and colleagues was to evaluate whether metabolic syndrome should be diagnosed already in obese pre-pubertal children and whether its prevalence is influenced by the inclusion of hepatic steatosis as a diagnostic criterion. Eighty-nine obese children (43 boys; age median [range], 8.5 [6-10] years) were enrolled. Metabolic syndrome was diagnosed according to a classic definition: presence of 3 or more of the following criteria-body mass index greater than 2 standard deviation score, triglycerides greater than the 95.sup.th percentile, high-density lipoprotein cholesterol less than the fifth percentile, blood pressure greater than the 95.sup.th percentile, and impaired glucose tolerance. Afterward, liver steatosis was included as an additional criterion to this definition. Metabolic syndrome was diagnosed in 12 children (13.5%) according to the first definition and in 18 children (20.2%) when liver steatosis was included. The prevalence of metabolic syndrome increased across homeostasis model assessment of insulin resistance tertiles (P for trend=0.01). The prevalence of the single components of the metabolic syndrome was as follows: central adiposity, 100%; hypertriglyceridemia, 27%; low high-density lipoprotein cholesterol, 2.2%; hypertension, 34.8%; impaired glucose tolerance, 4.5%; and nonalcoholic fatty liver disease, 21.3%. In conclusion, metabolic syndrome is common already among pre-pubertal obese children, particularly when hepatic steatosis is included among the diagnostic criteria. Therefore, screening for the metabolic syndrome should be performed in this age group; and hepatic steatosis should be considered as an additional diagnostic criterion.(62)
[0538] It seems clear from the extensive prior biomarker studies in animal models of Hepatitis C and NAFLD, summarized earlier in this example, that a biomarker approach can be relied upon to demonstrate favorable effects of Brake on reversal of NAFLD and associated cardiovascular diseases. Based on the unexpected but highly beneficial improvement in biomarkers and improved hepatic functioning after RYGB, it is a method of the present invention to treat NAFLD with a novel orally administered combination therapy of a statin, nominally for the first demonstration, atorvastatin or simvastatin and Brake. Every patient would receive Brake treatment that would be demonstrated to be active on the basis of lowered biomarkers of NAFLD in a pattern of elevation similar to that observed in our RYGB patients. In combination with oral Brake treatment as disclosed herein, the patient would also receive an approved front line treatment for hyperlipidemia such as simvastatin or atorvastatin, either of the statins given in the usual dose or in some novel regimens, given at less than half the usual dose. There are two tested reasons that Brake would improve both the efficacy and safety of statins in the treatment of NAFLD. First, both agents have side effects which are dose related, and in both cases using a lower dosage would still improve the efficacy and yet side effects would decrease. Secondly, the control of underlying metabolic syndrome promises true reversal of the NAFLD pathophysiology, which is tied to Brake associated reversal of insulin resistance, hyperlipidemia, hyperglycemia, hypertension and hepatic steatosis, all of which will be improved or resolved by including Brake in the combination therapy of NAFLD patients with metabolic syndromes.
[0539] Combination therapy between a statin and Brake for the surprising reversal of NAFLD is hereby incorporated by reference, with daily dosages of Simvastatin, Atorvastatin of 5-10 mg over-coated onto Brake of 10-20 grams daily, both active agents are presented as micro granules for oral administration to patients with NAFLD. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of hyperlipidemia to prevent the onset of metabolic syndrome associated damage to the heart and CV system, or at least delay its onset by many years. The disclosed combination product would be the first disease modifying treatment for this disease, here-to-fore considered to be irreversible.
[0540] Clinical proof of the utility of the synergistic combination of these NAFLD and associated hepatic regeneration therapies including Brake would necessitate the adoption of biomarkers of metabolic syndrome progression such as the FS index, which is an overall biomarker profile that can point to regenerative processes that respond to RYGB or Brake. Added to the metabolic syndrome biomarker profile of the FS index would be a biomarker profile of NAFLD progression to hepatocellular carcinoma or cirrhosis. This latter progression profile would focus on cardiac injury, include epigenetics, metabolomics and genomics where applicable, and imaging where applicable to loss of cardiac structure and function. To the extent that these biomarkers are improved by statins, those effects carry forward. To the extent that the observed improvement is tied to effects beyond those of atorvastatin or simvastatin, the conclusion would be Brake associated recovery or regeneration of hepatic function.
Example 7. Regeneration of the GI Tract
[0541] Use of the disclosed treatments and methods of modifying human gastrointestinal flora and the interaction between bacteria and L-cells of the ileum, for purposes of triggering regeneration of GI tract cells to benefit metabolic syndrome treatment are based on the findings incorporated by reference herein.
[0542] According to the teachings of Koehler, GLP-2 exerts pro-absorptive, regenerative, and cytoprotective actions in the normal and injured gut epithelium. Hence, sustained GLP-2 receptor (GLP-2R) activation represents a strategy under investigation for the prevention and treatment of chemotherapy-induced mucositis. It was found that GLP-2R activation engages signaling pathways promoting cell proliferation and cyto-protection in the normal gut epithelium, but also found that sustained direct or indirect modulation of GLP-2R signaling does not modify intestinal tumor cell growth or survival.(63)
[0543] Drucker noted that GLP-2 acts proximally to control energy intake by enhancing nutrient absorption and attenuating mucosa! injury and is currently marketed as Teduglutide by Takeda for the treatment of short bowel syndrome.(64) Moreover, GLP-2 receptor agonists appear to be promising therapies for the treatment of intestinal disorders. (65) GLP-2 also promotes intestinal cell proliferation and confers resistance to cellular injury in a variety of cell types. Administration of GLP-2 to animals with experimental intestinal injury promotes regeneration of the gastrointestinal epithelial mucosa and confers resistance to apoptosis in an indirect manner via yet-to-be identified. GLP-2 receptor-dependent regulators of mucosal growth and cell survival. These proliferative and anti-apoptotic actions of GLP-2 may contribute to protective and regenerative actions of these peptides in human subjects with T2D and intestinal disorders.(66)
[0544] Peptide hormones regulate cell viability and tissue integrity, directly or indirectly, through activation of G-protein-coupled receptors via diverse mechanisms including stimulation of cell proliferation and inhibition of cell death. Glucagon-like peptide-2 (GLP-2) is a 33 amino acid peptide hormone released from intestinal endocrine cells following nutrient ingestion. GLP-2 stimulates intestinal crypt cell proliferation leading to expansion of the gastrointestinal mucosal epithelium. Exogenous GLP-2 administration attenuates intestinal injury in experimental models of gastrointestinal disease and improves intestinal absorption and nutritional status in human patients with intestinal failure secondary to short bowel syndrome. GLP-2 also promotes mucosal integrity via reduction of injury-associated apoptosis in the intestinal mucosa and directly reduces apoptosis in cells expressing the GLP-2 receptor in vitro. Hence, the regenerative and cytoprotective properties of GLP-2 contribute to its therapeutic potential for the treatment of patients with intestinal disease.(67)
[0545] Endogenous GLP-2 regulates the intestinotropic response in re-fed mice through modulation of crypt-cell proliferation and villus apoptosis. GLP-2 is therefore a physiologic regulator of the dynamic adaptation of the gut mucosal epithelium in response to luminal nutrients.(68)
[0546] Perhaps the most profound example of GLP-2 action, including a near complete regeneration of GI endothelial lining cells themselves, follows RYGB surgery, where one aspect of the surgery is to connect the esophagus to mid-jejunum and completely bypass the duodenum. The result is major malabsorption of nutrients, which over the ensuing months after surgery is mitigated by GLP-2 remodeling of the jejunum into a section nearly as efficient as a section of duodenum. This is the very best definition of ileal brake associated GI remodeling and it happens in direct concert with regeneration of pancreatic beta cells and complete resolution of hepatic steatosis, all aspects mediated by the hormones of the ileal brake.
[0547] Le Roux studied the mechanistic linkages between changes in crypt cell proliferation and GLP-2 in rodents and man after RYGB. GLP-2 released from intestinal L-cells after nutrient intake stimulates intestinal crypt cell proliferation and mitigates the effects of gut injury. Wistar rats underwent either RYGB (n=6) or sham procedure (n=6) and plasma GLP-2, GLP-1, and PYY were measured after 23 days. In order to study the signaling and time course of these changes, biopsies from the terminal ileum were stained using the antibody to Ki67, which detects cyclins and hence demonstrates cells in the S-phase of the cell cycle. The total number of cells, number of mitosis, and number of labeled cells per crypt were counted. Obese patients (n=6) undergoing RYGB were evaluated following a 420 kcal meal preoperatively, and 1, 3, 6, 12, and 24 months later for responses in I-cell products such as GLP-2, GLP-1, total PYY, and PYY3-36. Rat GLP-2 levels after RYGB were elevated 91% above sham animals (P=0.02). At necropsy, mitotic rate (P<0.001) and cells positive for the antibody Ki67 (P<0.001) were increased, indicating crypt cell proliferation. Human GLP-2 after RYGB reached a peak at 6 months of 168% (P<0.01) above preoperative values. Area under the curve for GLP-1 (P<0.0001),total PYY (P<0.01), and PYY3-36 (P<0.05) responses increased progressively over 24 months. In both rodents and patients, RYGB leads to increased GLP-2 and mucosa! crypt cell proliferation. Other gut hormones from L-cells remain elevated for at least 2 years in humans. These findings may account for the restoration of the absorptive surface area of the gut, which limits malabsorption, regulates the interaction between nutrient intake and fat storage and contributes to the long-term weight loss after RYGB.(69)
[0548] One potential combination product with Brake, where the end result is restoration of the integrity of the small bowel, would be use of Brake with a small amount of a locally acting corticosteroid such as budesonide in a daily amount of 3.0 mg, where the goal of the steroid in the combination product is to lower the luminal inflammation in diseases like Croons and Ulcerative colitis. As these products are targeted for release also in the ileum or ascending colon, the practical aspect of co-formulation would be to combine the corticosteroid within the ileal brake hormone releasing substance core. In this case, all components of the formulation need to be released at the same site in the intestine, so the coating used for release of the ileal brake hormone releasing substance is sufficient for the entire components, that is to incorporate the second active drug as well. There are other short acting local steroids available as alternatives to budesonide, for example mometasone, ciclesonide, beclomethasone, fluticasone, flunisolide and other similar compounds that are topically active and metabolized locally, generally lacking systemic steroid activity and side effects. Said steroids are typically used by inhalation to treat conditions such as asthma, which also takes full advantage of their local action.
[0549] In another preferred embodiment of a Brake combination treatment for inflammatory bowel diseases, the combination may optionally include a probiotic bacterial organism or composition of probiotic organisms, in this case also formulated for release in the ileum or ascending colon, in a dosage of 10{circumflex over ()}6 to about 10{circumflex over ()}8 colony forming units. The purpose of this additional preferred active ingredient is to repair the intestinal dysbiosis which often accompanies the various forms of inflammatory bowel disease.
[0550] Weir and colleagues opined that this should also be an ideal approach to treatment of T1D, shutting off apoptosis and stimulating beta cell regeneration(70)
[0551] Bastien-Dione and colleagues have studied epigenetic signaling pathways and have previously shown that the forkhead transcription factor FOXO1 is a prominent transcriptional effector of GLP-1 signaling in the beta-cell. FOXO1 activity is subject to a complex regulation by Akt-dependent phosphorylation and SirT1-mediated deacetylation. In this study, they aimed at investigating the potential role of SirT1 in GLP-1 action. FOXO1 acetylation levels and binding to SirT1 were studied by Western immunoblot analysis in INS832/13 cells. SirT1 activity was evaluated using an in vitro deacetylation assay and correlated with the NAD(+)-to-NADH ratio. The implication of SirT1 in GLP-1-induced proliferation was investigated by BrdU incorporation assay. They determined beta-cell replication and mass in wild-type and transgenic mice with SirT1 gain of function after daily administration of exendin-4 for 1 week. Study data showed that GLP-1 increases FOXO1 acetylation, decreases the binding of SirT1 to FOXO1, and stunts SirT1 activity in beta-INS832/13 cells. GLP-1 decreases both the NAD(+)-to-NADH ratio and SirT1 expression in INS cells and isolated islets, thereby providing possible mechanisms by which GLP-1 could modulate SirT1 activity. Finally, the action of GLP-1 on beta-cell mass expansion is abolished in both transgenic mice and cultured beta-cells with increased dosage of SirT1. This study shows for the first time that GLP-1 modulates SirT1 activity and FOXO1 acetylation in beta-cells. They also identify SirT1 as a negative regulator of beta-cell proliferation.(71)
[0552] Paneth cells are locations for intestinal stem cells. Yilmaz et al studied caloric restriction and found that it promotes self-renewal of intestinal stem cells through the inhibition of mammalian target of rapamycin complex 1 (mTORC1) in Paneth cells. Paneth cell are packed together with LGRS (leu-rich repeat-containing G protein coupled receptor 5)-positive intestinal stem cells at the base of intestinal crypts. Calorie restriction was found to increase the numbers of Paneth cells and ISCs in mice. This observation, coupled with the fact that the number of differentiated enterocytes was reduced following calorie restriction, indicated that reduced calorie intake promotes self-renewal but not differentiation of ISCs. In addition, ISCs from calorie restricted mice displayed increased regenerative capacity as assayed by the ability of isolated crypts to form organoid bodies in vitro.
[0553] In summary, GI tract regenerative processes follow the activation of the ileal brake, and the fact that GLP-2 is somewhat specific for regeneration of luminal enterocytes is an advantage. If one can treat local conditions and add an overall stimulant of the ileal brake hormones to that local treatment, then a new and highly synergistic combination regimen can be offered for the treatment of local diseases of the GI tract such as inflammatory bowel diseases. Specific combinations of these components are offered for use in the treatment of inflammatory bowel disease, but it is recognized that there are many other localized GI diseases that may benefit from this approach.
Example 8. Kidney Regeneration and Joint Regeneration in RA Patients
[0554] Weight-loss surgery may reduce the risk of kidney disease progression in obese people with T2D, according to a small study. The study included 52 patients, mostly female, who were obese and had T2D. Nearly 40 percent of the patients had diabetic nephropathy, a form of kidney damage that can require dialysis and lead to kidney failure. All of the patients underwent RYGB surgery Five years after surgery, nearly 60 percent of the patients whod had diabetic nephropathy no longer had the condition. They also found that only 25 percent of those who did not have diabetic nephropathy at the time of surgery eventually developed the condition. That's about 50 percent less than the occurrence rate in people with T2D who don't have bariatric surgery. The five-year T2D remission and improvement rates for patients in the study were 44 percent and 33 percent, respectively. Over half the patients who had diabetic nephropathy prior to undergoing bariatric surgery experienced remission. This is a remarkable finding that warrants greater consideration of bariatric surgery in this patient population. About 90 percent of people with T2D worldwide are overweight or obese, according to the World Health Organization. In the study, patients' average body-mass indexa measure of body fat based on height and weightwas 49 at the time of the surgery. A body-mass index of 30 or higher is considered obese. Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal. Experts also note that although the study found an association between weight-loss surgery and less kidney damage, researchers did not prove that the surgery was responsible for the decreased kidney disease.
[0555] Angiotensin II inhibitors are the mainstay treatment for diabetic kidney diseases and all AII inhibitors show a dose related lowering of proteinuria. Some AII inhibitors have shown a reduction in cardiovascular risk profile and in the risk of progression to dialysis. This may be achieved by proteinuria lowering or it may be result of reduced inflammation, or both. RYGB surgery on the other hand, has a modest lowering of serum creatinine in our patients, but a dramatic evidence of organ and tissue regeneration, including in the heart and blood vessels. One aspect of the greater effect of RYGB surgery is its impact across the dietary supply side pathways of sugar and fat, T2D and hyperglycemia, all significant risk factors for diabetic nephropathy. Evidence favoring the combination approach of an orally active RYGB mimetic with a statin is provided below. Subsequently, the inventors disclose our own findings demonstrating the synergistic effects of the combination product of controlled release Brake over-coated with 10 mg of a lisinopril or a suitable ACE inhibitor or suitable Angiotensin II inhibitors such as Losartan, candesartan, irbesartan, olmesartan, valsartan or any other suitable AII inhibitor.
[0556] The pharmaceutical composition used to treat diabetic nephropathy and orally active on the ileal brake as disclosed herein, may be over-coated with any AII inhibitor such that the daily dose is the same as usually given in conjunction with 7 Brake pills, in a weight ratio of approximately 0.008 parts AII inhibitor to each 1.0 part refined sugar or approximately 0.005 part AII inhibitor:1.0 part refined sugar (e.g. AII inhibitors selected from the group consisting of olmesartan, losartan, valsartan and any other suitable sartan compound); the enteric coated core of the pharmaceutical composition may also comprise approximately 60-80% refined sugar, 0-40% of a plant-derived lipid; and/or when apportioning daily dose of losartan onto the daily dose of ileal brake hormone releasing substance in the enteric coated tablet form, the 1.0 gram tablets are over-coated with the immediate release losartan.
[0557] An additional embodiment of the Brake controlled release of ileal brake hormones formulation is the use of the product for the treatment of rheumatoid arthritis, typically in combination with methotrexate. Methotrexate is effective in relieving joint inflammation and pain, slowing disease progression, and preventing disability by delaying joint destruction. Patients with rheumatoid arthritis may be more likely to continue treatment with methotrexate than with other DMARDs because of favorable results and tolerable side effects. Studies indicate that more than 50% of people who take methotrexate for rheumatoid arthritis continue taking the medicine for more than 3 years, which is longer than any other DMARD.
[0558] Methotrexate is often the first DMARD prescribed for rheumatoid arthritis and usually provides relatively fast relief of at least some symptoms. Patients who can tolerate methotrexate, but it is not sufficiently effective, will be given a second DMARD along with methotrexate (combination therapy). Several recent studies report that treatment results are improved when methotrexate is given with another DMARD. For example, one study found that methotrexate used in combination with etanercept, a new DMARD, is more effective at reducing disease activity than methotrexate alone. Studies with infliximab and adalimumab have shown similar results
[0559] Combination therapy may allow for lower doses of an individual drug to be used, which may reduce the risk of adverse effects that can occur with higher doses. In one large review of studies, various combinations of DMARDs plus methotrexate were more effective than either methotrexate or another DMARD alone. Accordingly, a methotrexate daily dose of 1.0 mg will be over-coated onto the 7 Brake pills that constitute a single daily dose. The name of this new treatment for Rheumatoid Arthritis is TrexaBrake As noted by Westlake and colleagues, patients with RA have an increased prevalence of cardiovascular disease (CVD). This is due to traditional risk factors and the effects of chronic inflammation. Methotrexate (MTX) is the first-choice DMARD in RA. They performed a systematic literature review to determine whether MTX affects the risk of CVD in patients with RA. They searched Medline, Embase, Cochrane database, database of abstracts of reviews of effects, health technology assessment and Science Citation Index from 1980 to 2008. Conference proceedings (British Society of Rheumatology, ACR and EULAR) were searched from 2005 to 2008. Papers were included if they assessed the relationship between MTX use and CVD in patients with RA. Two reviewers independently assessed each title and abstract for relevance and quality. A total of 2420 abstracts were identified, of which 18 fulfilled the inclusion criteria. Two studies assessed the relationship between MTX use and CVD mortality, one demonstrated a significant reduction in CVD mortality and the second a trend towards reduction. Five studies considered all-cause CVD morbidity. Four demonstrated a significant reduction in CVD morbidity and the fifth a trend towards reduction. MTX use in the year prior to the development of RA decreased the risk of CVD for 3-4 years. Four studies considered myocardial infarction, one demonstrated a decreased risk and three a trend towards decreased risk with MTX use. According to Westlake, MTX use is associated with a reduced risk of CVD events in patients with RA. This suggests that reducing the inflammation in RA using MTX not only improves disease-specific outcomes but may also reduce collateral damage such as atherosclerosis.(72). TrexaBrake is anticipated to be highly protective of the CV system when used in the treatment of Rheumatoid Arthritis.
Example 9. Treatment of COPD and Regeneration of Pulmonary Function and Lung Integrity
[0560] The pathophysiology of COPD involves a complex series of chronic inflammatory processes that progressively destroy the pulmonary vasculature and lung parenchyma Two main pathophysiological processes occur in COPD: inflammation and unopposed oxidation.
[0561] The inflammatory process is believed to be mediated by chemical factors, such as tumor necrosis factor-alpha (TNF-a), interleukin-8 (IL-8), and leukotriene B4. When noxious gases or particles have been introduced into the lungs and irritation has occurred, the chemical messengers propagate the inflammatory process and recruit neutrophils, macrophages, and lymphocytes to the site of injury.
[0562] The second pathophysiological process involves a shift in the balance of normal defense mechanisms, resulting in unopposed oxidation. Guidelines from the Global Initiative for Chronic Obstructive Lung Disease (GOLD) identify disruption of the oxidant/antioxidant or trypsin/antitrypsin balance as a major determinant of damage to the lung parenchyma Tobacco has been implicated in the disruption of both processes by (1) increasing oxidation, thereby overwhelming antioxidant protective factors, and (2) inducing proteases from macrophages and neutrophils. Tobacco smoke has thus been identified as the single greatest risk factor for COPD because of the processes of cellular damage and because of the high incidence of tobacco use worldwide.
[0563] The impact of central adiposity on pulmonary function remains unclear, particularly beyond the obvious mechanical challenges to breathing conferred by central adiposity. Reductions in chest wall compliance and respiratory muscle strength due to a high percent body fat and localized fat distribution contributes to impaired pulmonary function and the occurrence of adverse respiratory symptoms. Effective weight loss after bariatric surgery may improve cardiovascular disease risk factors, including T2D, hypertension, dyslipidemia, atherosclerosis, inflammation, chronic kidney disease, obstructive sleep apnea, and hypoventilation syndrome. Bariatric surgery has also been associated with significantly improved respiratory symptoms and pulmonary function, and the authors present a review of principal studies that correspond to the reversal of respiratory symptoms and impaired pulmonary function after bariatric surgery.(73) Clearly, there is an element of improvement that is notably linked to weight reduction, which is expected when here is restriction of the chest wall. However, the data do favor some improvements in pulmonary function itself. There is some debate whether lungs of adult humans regenerate(74), but on a logical basis it would be more surprising if they did not, rather than they did. Perhaps the best evidence for pulmonary regeneration comes from patients that have undergone pneumonectomy, usually for a respectable carcinoma of the lung. By way of example, a recent paper by Butler and colleagues reported on a 33-year-old woman who underwent a right-sided pneumonectomy in 1995 for treatment of a lung adenocarcinoma. As expected, there was an abrupt decrease in her vital capacity to approximately half of normal, but unexpectedly, it increased during the subsequent 15 years to reach values similar to normal for age. Serial computed tomographic (CT) scans on this patient showed progressive enlargement of the remaining left lung and an increase in tissue density. Magnetic resonance imaging (MRI) with the use of hyperpolarized helium-3 gas showed overall acinar-airway dimensions that were consistent with an increase in the alveolar number rather than the enlargement of existing alveoli, but the alveoli in the growing lung were shallower than in normal lungs. This study provides evidence that new lung growth can occur in an adult human.(75) On the basis of this demonstrable growth and the improvements after RYGB surgery, It is judged that Brake treatment would produce similar regeneration evidence but not necessarily as much weight loss related improvement as RYGB, since Brake treated patients do not lose as much weight as RYGB treated patients.
[0564] Apart from smoking cessation, there are no other treatments that slow the decline in lung function. Roflumilast and cilomilast are oral phosphodiesterase 4 (PDE-N) inhibitors proposed to reduce the airway inflammation and bronchoconstriction seen in COPD. On a cellular level, PDE4 converts cAMP to adenosine monophosphate (AMP), terminating the cellular messaging initiated by cAMP. Roflumilast blocks the effect of PDE-IV, leading to an accumulation of cAMP within target cells and a corresponding increase in cAMP messaging. The clinical relevance of blocking PDE-N is unknown. However, it is thought that the accumulation of cAMP within localized immune cells and lung tissue is important in preventing the pathogenesis of COPD, particularly inflammation.
[0565] Recently, Chong and colleagues reviewed the efficacy and safety of PDE-IV inhibitors in the management of people with stable COPD. Outcomes included lung function, quality of life, symptoms, exacerbations and adverse effects, in all cases where PDE-IV inhibitors were compared to placebo. Twenty-three separate RCTs studying roflumilast (nine trials, 9211 patients) or cilomilast (fourteen trials, 6457 patients) met the inclusion criteria. None of the trials exceeded a year in duration. Treatment with a PDE-IV inhibitor was associated with a significant improvement in FEV(I)over the trial period compared with placebo (MD 45.59 mL; 95% confidence interval (CI) 39.15 to 52.03), regardless of COPD severity or concomitant COPD treatment. There were some small improvements in quality of life (St George's Respiratory Questionnaire MD 1.04; 95% CI 1.66 to 0.4 1) and COPD-related symptoms, but no change in exercise tolerance. Treatment with a PDE-IV inhibitor was associated with. a reduced likelihood of COPD exacerbation (OR 0.78; 95% CI 0.72 to 0.85). More participants in the treatment groups experienced non-serious adverse events compared with controls, particularly gastrointestinal symptoms and headache. Roflumilast was associated with weight loss during the trial period. In the conclusion of the authors, PDE-IV inhibitors offered benefit over placebo in improving lung function and reducing likelihood of exacerbations, however, they had little impact on quality of life or symptoms. Gastrointestinal adverse effects and weight loss were common. Longer-term trials are needed to determine whether or not PDE-IV inhibitors modify FEV(I) decline, healthcare utilization or mortality in COPD.(76)
[0566] Clearly, adding further control of metabolic syndrome to the PDE-IV pathway, such as combining Brake with an over-coating of Roflumilast, would be the most promising means of regeneration of pulmonary function. The daily dose of Roflumilast in this case would be the same as typically used, 500 mcg per day,
[0567] However, the study of Butler and colleagues show that the combination should be given for longer time periods in order to clearly improve pulmonary function, since the rate of regeneration appears to be slower than short term studies which have been conducted thus far. Although most of the Brake combination products have effected maximal regeneration at 6 months, it is not clear at this time if 6 months of the combination product would be sufficient to demonstrate pulmonary regeneration.
Example 10. Alzheimer's Disease Biomarkers and Treatments
[0568] In recent years a rapidly increasing number of studies have examined the relationship between dementia and metabolic disorders such as T2D, central adiposity, hypertension, and dyslipidemia. Etiological heterogeneity and comorbidity pose challenges for determining relationships among metabolic disorders. The independent and interactive effects of brain vascular injury and classic pathological agents such as beta-amyloid have also proved difficult to distinguish in human patients, blurring the lines between Alzheimer's disease and vascular dementia. Craft and colleagues highlight recent work aimed at identifying convergent mechanisms such as insulin resistance that may underlie comorbid metabolic disorders and thereby increase dementia risk.(77)
[0569] Recent studies demonstrate that metabolic syndrome manifestations including central adiposity are independently associated with poor neurocognitive outcomes, including cognitive impairment, increased risk for dementia, and regional alterations in brain structure.(78-89) RYGB surgery is an effective treatment for obesity and initial findings by Stanek and others suggest that it may result in cognitive improvements.(90). Our own findings (1) show marked improvement in biomarkers of Alzheimer's disease following RYGB surgery, effectively positioning the instant invention Brake for use concomitantly with known treatments for this condition, such as memantine.
[0570] Our recent study of RYGB patients using Alzheimer's biomarkers support the clinical case for improvement in cognition as metabolic syndrome relents. RYGB demonstrates a novel pathway for mitigation of Alzheimer's and we propose that RYGB is impacting cognition by virtue of its impact on underlying metabolic syndrome. RYGB may have other beneficial effects, such as reduction in beta amyloid accumulation in neural tissues. Accordingly we present the evidence linking progression of Alzheimer's disease to progression of metabolic syndrome. Ghanim and Colleagues reported on Alzheimer's biomarkers in patients who had RYGB surgery.(1). Obesity and T2D are known to be associated with an increase in the incidence and prevalence of Alzheimer's disease (AD) and an impaired cognitive function. Because peripheral blood mononuclear cells (MNC) express amyloid precursor protein (APP), the precursor of beta-amyloid, which forms the pathognomonic plaques in the brain, they hypothesized that APP expression diminishes after the marked caloric restriction and reduction in systemic inflammation associated with RYGB surgery. Fifteen T2D patients with morbid obesity (BMI, 52.1+1-13) underwent RYGB, and the expression of inflammatory and AD-related genes was examined before and after 6 months in plasma and in MNC. BMI fell to 40.4+1-11.1 at 6 months after RYGB. There was a significant fall in plasma concentrations of glucose and insulin and in HOMA-IR. The expression of APP mRNA fell by 31+1-9%, and that of protein fell by 36+1-14%. In addition, there was a reduction in the expression of other AD-related genes including presinilin-2, ADAM-9, GSK-3beta, PICALM, SORL-1, and clusterin (P<0.05 for all). Additionally, the expression of c-Fos, a subunit of the pro-inflammatory transcription factor AP-1, was also suppressed after RYGB. These changes occurred in parallel with reductions in other pro-inflammatory mediators including C-reactive protein and monocyte chemoattractant protein-1. Thus, the reversal of the pro-inflammatory state of metabolic syndrome is associated with a concomitant reduction in the expression of APP and other AD-related genes in MNC. If indeed, this effect also occurs in the brain, there are major implications for the pathogenesis and the treatment of AD. It is relevant that cognitive function has been shown to improve with weight loss following RYGB surgery(90).
[0571] Based on the unexpected but highly beneficial improvement in biomarkers and cognition after RYGB, it is an additional aspect of the present invention to treat early Alzheimer's disease with a novel combination oral therapy of an Alzheimer's drug and Brake. Every patient would receive Brake treatment that would be demonstrated to be active on the basis of lowered biomarkers of Alzheimer's in a pattern of elevation similar to that observed in our RYGB patients. In combination with oral Brake treatment as disclosed herein, the patient would also receive an approved front line treatment for Alzheimer's such as donepezil or memantine, either of these therapeutics given in the usual dose over-coated onto the 7 Brake tablets, or in some novel regimens, given at half the usual dose.
[0572] There are two tested reasons that Brake would improve both the efficacy and safety of donepezil or memantine in Alzheimer's disease. First, both agents have side effects which are dose related, and in both cases using a lower dosage would still improve the efficacy and yet side effects would decrease. Secondly, the control of underlying metabolic syndrome promises true reversal of the Alzheimer's pathophysiology, which is tied to Brake associated reversal of in some resistance, hyperlipidemia, hyperglycemia, hypertension and hepatic steatosis, all of which will be improved or resolved by including Brake in the combination therapy of Alzheimer's patients with metabolic syndromes.
[0573] Combination therapy between donepezil and Brake for the surprising reversal of Alzheimer's disease pathophysiology is hereby incorporated by reference, with dosages of Donepezil of 5-10 mg daily and doses of Brake of 10-20 grams daily, both active agents are presented as micro granules for oral administration to patients with Alzheimer's disease. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of Alzheimer's to prevent the onset of metabolic syndrome associated damage leading to Alzheimer's, or at least inhibit or delay its onset by many years. The disclosed combination product would be the first disease modifying treatment for this disease, here-to-fore considered to be irreversible.
[0574] Clinical proof of the utility of the synergistic combination of these Alzheimer's disease therapies including Brake would necessitate the adoption of biomarkers of metabolic syndrome progression such as the FS index, which is an overall biomarker profile that can point to regenerative processes that respond to RYGB or Brake. Added to the metabolic syndrome biomarker profile of the FS index would be a biomarker profile of Alzheimer's disease progression. This latter progression profile would focus on cognition, genomics where applicable, and imaging where applicable to loss of brain tissue and neuronal mass. To the extent that these biomarkers are improved by donepezil, those effects carry forward. To the extent that the observed improvement is tied to effects beyond those of donepezil, the conclusion would be Brake associated recovery or regeneration of functioning neurons.
[0575] Okereke and colleagues have studied the relationships between dietary factors and cognitive decline. Their study examined dietary fat types in relation to cognitive change in healthy community-based elders. Among 6,183 older participants in the Women's Health Study, they related intake of major fatty acids [saturated [SFA], monounsaturated [MUFA], total polyunsaturated [PUFA], trans-unsaturated) to late-life cognitive trajectory. Serial cognitive testing, conducted over 4 years, began 5 years after initial dietary assessment. Primary outcomes were global cognition and verbal memory. They used analyses of response profiles and logistic regression to estimate multivariate-adjusted differences in cognitive trajectory and risk of worst cognitive change (worst 10%) by fat intake. Higher SFA intake was associated with worse global cognitive (p for linear trend=0.008) and verbal memory (p for linear trend=0.01) trajectories. There was a higher risk of worst cognitive change, comparing highest versus lowest SFA quintiles; the multivariate-adjusted odds ratio (OR) with 95% confidence interval (CI) was 1.64 (1.04-2.58) for global cognition and 1.65 (1.04-2.61) for verbal memory. By contrast, higher MUFA intake was related to better global cognitive (p for linear trend<0.001) and verbal memory (p for linear trend=0.009) trajectories, and lower OR (95% CI) of worst cognitive change in global cognition (0.52 [0.31-0.88]) and verbal memory (0.56 [0.34-0.94]). Total fat, PUFA, and trans-fat intakes were not associated with cognitive trajectory. Thus, higher SFA intake was associated with worse global cognitive and verbal memory trajectories, whereas higher MUFA intake was related to better trajectories (91)
[0576] Bayer-Carter and colleagues also examined dietary links to Alzheimer's using similar methods. They compared the effects of a 4-week high-saturated fat/high-glycemic index (IDGH) diet with a low-saturated fat/low-glycemic index (LOW) diet on insulin and lipid metabolism, cerebrospinal fluid (CSF) markers of Alzheimer disease, and cognition for healthy adults and adults with amnestic mild cognitive impairment (aMCI). The study was performed in a clinical research unit. Forty-nine older adults (20 healthy adults with a mean [SD] age of 69.3 [7.4] years and 29 adults with aMCI with a mean [SD] age of 67.6 [6.8] years) received the HIGH diet (fat, 45% (saturated fat, >25%); carbohydrates, 35%-40% [glycemic index, >70]; and protein, 15%-20%) or the LOW diet (fat, 25%; [saturated fat, <7%]; carbohydrates, 55%-60% [glycemic index, <55]; and protein, 15%-20%) for 4 weeks. Cognitive tests, an oral glucose tolerance test, and lumbar puncture were conducted at baseline<id during the fourth week of the diet. CSF concentrations of beta-amyloid (Abeta42 and Abeta40), tau protein, insulin, F2-isoprostanes, and apolipoprotein E, and plasma lipids and insulin, and measures of cognition were all performed. For the a MCI group, the LOW diet increased CSF Abeta42 concentrations, contrary to the pathologic pattern of lowered CSF Abeta42 typically observed in Alzheimer's disease. The LOW diet had the opposite effect for healthy adults, i.e., decreasing CSF Abeta42, whereas the HIGH diet increased CSF Abeta42. The CSF apolipoprotein E concentration was increased by the LOW diet and decreased by the HIGH diet for both groups. For the aMCI group, the CSF insulin concentration increased with the LOW diet, but the HIGH diet lowered the CSF insulin concentration for healthy adults. The HIGH diet increased and the LOW diet decreased plasma lipids, insulin, and CSF F2-isoprostane concentrations. Delayed visual memory improved for both groups after completion of 4 weeks of the LOW diet. These results suggested that diet may be a powerful environmental factor that modulates Alzheimer disease risk through its effects on central nervous system concentrations of Abeta42, lipoproteins, oxidative stress, and insulin.(92)
[0577] Patients with Alzheimer's disease (AD) have elevations of fasting plasma insulin that are hypothesized to be associated with disrupted brain insulin metabolism. Craft and colleagues examined paired fasted plasma and CSF insulin levels in 25 patients with AD and 14 healthy age-matched adults and determined whether insulin levels were related to severity of dementia and apolipoprotein E-epsilon-4 homozygosity, a known genetic risk factor for AD. The AD patients had lower CSF insulin, higher plasma insulin, and a reduced CSF-to-plasma insulin ratio when compared with healthy adults. The differences were greater for patients with more advanced AD. Patients who were not apolipoprotein E-epsilon4 homozygotes had higher plasma insulin levels and reduced CSP-to-plasma ratios, whereas epsilon4 homozygotes with AD had normal values. Both plasma and CSF insulin levels are abnormal in AD, and there are metabolic differences among apolipoprotein E genotypes.(93)
[0578] Because little is known regarding factors such as insulin and soluble amyloid beta peptide (Abeta) concentrations in humans at late midlife, Townsend et al measured plasma Abeta42, Abeta40, fasting insulin, and c-peptide in 468 women without T2D, aged 59 to 69 years (median 63 y). Before blood draw, participants reported BMI, waist circumference, physical activity, alcohol intake, hypertension, and T2D family history. Linear regression was used to calculate age-adjusted mean differences in Abeta42 to Abeta40 ratio, and Abeta42 levels, by insulin and insulin-related factors. The ratio of Abeta42 to Abeta40 was statistically significantly lower in women with family history of T2D, and Abeta42 was significantly lower with less physical activity, greater waist circumference, hypertension, and family history of T2D (P<0.05 for all). Abeta42 to Abeta40 ratio, and Abeta42 levels, appeared lower with higher c-peptide levels (P trend=0.07 and 0.06, respectively), although these were not statistically significant. In summary, insulin-related factors appear associated with lower plasma Abeta42 to Abeta40 ratio, and Abeta42, at late midlife, consistent with increased brain sequestration of Abeta42 (relative to Abeta40), suggesting insulin merits focus in strategies to prevent dementia. (94)
[0579] Scanning is a recognized technology for evaluating progression of Alzheimer's disease. Novak and colleagues examined the effects of inflammation on perfusion regulation and brain volumes in T2D. A total of 147 subjects (71 diabetic and 76 non-diabetic, aged 65.2+1-8 years) were studied using 3T anatomical and continuous arterial spin labeling MRI. Analysis focused on the relationship between serum soluble vascular and intercellular adhesion molecules (sVCAM and sICAM, respectively, both markers of endothelial integrity), regional vasoreactivity, and tissue volumes. T2D subjects had greater vasoconstriction reactivity, more atrophy, depression, and slower walking. Adhesion molecules were specifically related to gray matter atrophy (P=0.04) and altered vasoreactivity (P=0.03) in the diabetic and control groups. Regionally, sVCAM and sICAM were linked to exaggerated vasoconstriction, blunted vasodilatation, and increased cortical atrophy in the frontal, temporal, and parietal lobes (P=0.04-0.003). sICAM correlated with worse functionality. Via MRI, T2D was associated with cortical atrophy, vasoconstriction, and worse performance. Adhesion molecules, as markers of vascular health, contributed to altered vasoregulation and atrophy.(95)
[0580] The review article by Sellbom integrates the recent literature regarding patterns of obesity-related cognitive dysfunction and brain alterations and also indicates potential mechanisms for these neuropathological changes. The Sellborn review culminates in a preliminary model of obesity-related cognitive dysfunction and suggestions for future research, including the potential reversibility of these changes with weight-loss. (80) Increasing incidence of metabolic syndrome manifestations including obesity and T2D are already firmly linked to progression of Alzheimer's and there are a large series of biomarkers and mediators summarized below from available literature, and in addition to the summary provided below, they are hereby incorporated into this application by reference.
[0581] A third approach to Alzheimer's disease is then enabled by the results with Brake in combination with these older front line drugs, and that is the potential for combination between Brake and newer molecules that act to reverse Alzheimer's action in the brain itself. One example of this is Bapineuzumab (96-106), which is thought to remove amyloid from brain tissues by blocking the action of the gene coding ApoE4. Combination therapy between Bapineuzumab and Brake for the surprising reversal of Alzheimer's disease pathophysiology is hereby incorporated by reference, with effective injected dosages of Bapineuzumab and daily oral doses of Brake of 10-20 grams daily, to patients with Alzheimer's disease. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of Alzheimer's to prevent the brainprogression of Alzheimer's disease as well as prevent the onset or progression of metabolic syndrome associated Alzheimer's, or at least delay it by many years. The disclosed combination product would be a new disease modifying treatment for this disease here-to-fore considered to be irreversible.
[0582] It is apparent that one skilled in the art, who also had discovered another disease modifying molecule for treatment of Alzheimer's disease, could combine said agent with Brake and produce a highly effect and very broad spectrum treatment for Alzheimer's disease, and these combinations are hereby incorporated by reference.
[0583] In recent years a rapidly increasing number of studies have examined the relationship between dementia and metabolic disorders such as T2D, hepatic steatosis, hypertension, and dyslipidemia. Etiological heterogeneity and comorbidity pose challenges for determining relationships among metabolic disorders. The independent and interactive effects of brain vascular injury and classic pathological agents such as beta-amyloid have also proved difficult to distinguish in human patients, blurring the lines between Alzheimer's disease and vascular dementia. Craft and colleagues highlight recent work aimed at identifying convergent mechanisms such as insulin resistance that may underlie comorbid metabolic disorders and thereby increase dementia risk.(77)
[0584] Bayer-Carter and colleagues also examined dietary links to Alzheimer' s using similar methods. They compared the effects of a 4-week high-saturated fat/high-glycemic index (HIGH) diet with a low-saturated fat/low-glycemic index (LOW) diet on insulin and lipid metabolism, cerebrospinal fluid (CSF) markers of Alzheimer disease, and cognition for healthy adults and adults with amnestic mild cognitive impairment (aMCI). The study was performed in a clinical research unit. Forty-nine older adults (20 healthy adults with a mean [SD] age of 69.3 [7.4] years and 29 adults with a MCI with a mean [SD] age of 67.6 [6.8] years) received the HIGH diet (fat, 45% [saturated fat, >25%]; carbohydrates, 35%-40% [glycemic index,>70]; and protein, 15%-20%) or the LOW diet (fat, 25%; [saturated fat, <7%]; carbohydrates, 55%-60% [glycemic index,<55]; and protein, 15%-20%) for 4 weeks. Cognitive tests, an oral glucose tolerance test, and lumbar puncture were conducted at baseline and during the fourth week of the diet. CSF concentrations of beta-amyloid (Abeta42 and Abeta40), tau protein, insulin, F2-isoprostanes, and apolipoprotein E, and plasma lipids and insulin, and measures of cognition were all performed. For the a MCI group, the LOW diet increased CSF Abeta42 concentrations, contrary to the pathologic pattern of lowered CSF Abeta42 typically observed in Alzheimer's disease. The LOW diet had the opposite effect for healthy adults, i.e., decreasing CSF Abeta42, whereas the HIGH diet increased CSP Abeta42. The CSF apolipoprotein E concentration was increased by the LOW diet and decreased by the HIGH diet for both groups. For the aMCI group, the CSF insulin concentration increased with the LOW diet, but the HIGH diet lowered the CSF insulin concentration for healthy adults. The HIGH diet increased and the LOW diet decreased plasma lipids, insulin, and CSF F2-isoprostane concentrations. Delayed visual memory improved for both groups after completion of 4 weeks of the LOW diet. These results suggested that diet may be a powerful environmental factor that modulates Alzheimer disease risk through its effects on central nervous system concentrations of Abeta42, lipoproteins, oxidative stress, and insulin.(92)
[0585] Patients with Alzheimer's disease (AD) have elevations of fasting plasma insulin that are hypothesized to be associated with disrupted brain insulin metabolism. Craft and colleagues examined paired fasted plasma and CSF insulin levels in 25 patients with AD and 14 healthy age-matched adults and determined whether insulin levels were related to severity of dementia and apolipoprotein E-epsilon4 homozygosity, a known genetic risk factor for AD. The AD patients had lower CSF insulin, higher plasma insulin, and a reduced CSF-to-plasma insulin ratio when compared with healthy adults. The differences were greater for patients with more advanced AD. Patients who were not apolipoprotein E-epsilon4 homozygotes had higher plasma insulin levels and reduced CSF-to-plasma ratios, whereas epsilon4 homozygotes with AD had normal values. Both plasma and CSF insulin levels are abnormal in AD, and there are metabolic differences among apolipoprotein E genotypes.(93)
[0586] Because little is known regarding factors such as insulin and soluble amyloid beta pepT1De (Abeta) concentrations in humans at late midlife, Townsend et al measured plasma Abeta42, Abeta40, fasting insulin, and c-pepT1De in 468 women without T2D, aged 59 to 69 years (median 63 y). Before blood draw, participants reported BMI, waist circumference, physical activity, alcohol intake, hypertension, and T2D family history. Linear regression was used to calculate age-adjusted mean differences in Abeta42 to Abeta40 ratio, and Abeta42 levels, by insulin and insulin-related factors. The ratio of Abeta42 to Abeta40 was statistically significantly lower in women with family history of T2D, and Abeta42 was significantly lower with less physical activity, greater waist circumference, hypertension, and family history of T2D (P<0.05 for all). Abeta42 to Abeta40 ratio, and Abeta42 levels, appeared lower with higher c-peptide levels (P trend=0 0.07 and 0.06, respectively), although these were not statistically significant. In summary, insulin-related factors appear associated with lower plasma Abeta42 to Abeta40 ratio, and Abeta42, at late midlife, consistent with increased brain sequestration of Abeta42 (relative to Abeta40), suggesting insulin merits focus in strategies to prevent dementia.(94)
[0587] Scanning is a recognized technology for evaluating progression of Alzheimer's disease. Novak and colleagues examined the effects of inflammation on perfusion regulation and brain volumes in T2D. A total of 147 subjects (71 diabetic and 76 non diabetic, aged 65.2+1-8 years) were studied using 3T anatomical and continuous arterial spin labeling MRI. Analysis focused on the relationship between serum soluble vascular and intercellular adhesion molecules (sVCAM and sICAM, respectively, both markers of endothelial integrity), regional vasoreactivity, and tissue volumes. T2D subjects had greater vasoconstriction reactivity, more atrophy, depression, and slower walking. Adhesion molecules were specifically related to gray matter atrophy (P=0.04) and altered vasoreactivity (P=0.03) in the diabetic and control groups. Regionally, sVCAM and sICAM were linked to exaggerated vasoconstriction, blunted vasodilatation, and increased cortical atrophy in the frontal, temporal, and parietal lobes (P=0.04-0.003). sICAM correlated with worse functionality. Via MRJ, T2D was associated with cortical atrophy, vasoconstriction, and worse performance. Adhesion molecules, as markers of vascular health, contributed to altered vasoregulation and atrophy.(95)
[0588] The Sellbom review culminates in a preliminary model of obesity-related cognitive dysfunction and suggestions for future research, including the potential reversibility of these changes with weight-loss. (80) Increasing obesity and T2D are already firmly linked to progression of Alzheimer's and there are a large series of biomarkers and mediators summarized below from available literature, and in addition to the summary provided below, they are hereby incorporated into this application by reference.
[0589] Recent studies demonstrate that metabolic syndrome is independently associated with poor neurocognitive outcomes, including cognitive impairment, increased risk for dementia, and regional alterations in brain structure.(78-89) RYGB surgery is an effective treatment for metabolic syndrome and initial findings by Stanek and others suggest that it may result in cognitive improvements.(90).
[0590] Based on the unexpected but highly beneficial improvement in biomarkers and cognition after RYGB, it is a further aspect of the invention to treat early Alzheimer's disease with a novel combination oral therapy of an Alzheimer's drug and Brake. Every patient would receive Brake treatment that would be demonstrated to be active on the basis of lowered biomarkers of Alzheimer's in a pattern of elevation similar to that observed in our RYGB patients. In combination with oral Brake treatment as disclosed herein, the patient would also receive an approved front line treatment for Alzheimer's such as donepezil or memantine, either of these therapeutics given in the usual dose or in some novel regimens, given at 50% to 80% or even less (e.g. 20% to 35%) of the usual dose. There are two tested reasons that Brake would improve both the efficacy and safety of donepezil or memantine in Alzheimer's disease. First both agents have side effects which are dose related, and in both cases using a lower dosage would still improve the efficacy and yet side effects would decrease. Secondly, the control of underlying metabolic syndrome promises true reversal of the Alzheimer's pathophysiology, which is tied to Brake associated reversal of insulin resistance, hyperlipidemia, hyperglycemia, hypertension and hepatic steatosis, all of which will be improved or resolved by including Brake in the combination therapy of Alzheimer's patients with metabolic syndromes.
[0591] Combination therapy between donepezil and Brake for the surprising reversal of Alzheimer's disease pathophysiology is hereby incorporated by reference, with dosages of Donepezil of 5-10 mg daily and doses of Brake of 10-20 grams daily, both active agents are presented as micro granules for oral administration to patients with Alzheimer's disease. This combination has the surprising potential, when used in conjunction with biomarkers defining early risk of Alzheimer's to prevent the onset of metabolic syndrome associated damage leading to Alzheimer's, or at least delay its onset by many years. The disclosed combination product would be the first disease modifying treatment for this disease, here-to-fore considered to be irreversible.
[0592] Clinical proof of the utility of the synergistic combination of these Alzheimer's disease therapies including Brake would necessitate the adoption of biomarkers of metabolic syndrome progression such as the FS index, which is an overall biomarker profile that can point to regenerative processes that respond to RYGB or Brake. Added to the metabolic syndrome biomarker profile of the FS index would be a biomarker profile of Alzheimer's disease progression. This latter progression profile would focus on cognition, genomics where applicable, and imaging where applicable to loss of brain tissue and neuronal mass (apoptosis). To the extent that these biomarkers are improved by donepezil, those effects carry forward. To the extent that the observed improvement is tied to effects beyond those of donepezil, the conclusion would be Brake associated recovery or regeneration of functioning neurons.
[0593] It is apparent that one skilled in the art who also had discovered another disease modifying molecule for treatment of Alzheimer's (an anti-Alzheimer's agent) could combine said agent with Brake and produce a highly effect and very broad spectrum treatment for Alzheimer's disease, and these combinations are another aspect of the present invention.
