Description

DETAILED DESCRIPTION OF THE INVENTION

[0029] Cardiovascular disease (CVD) is the most common co-morbidity associated with COVID-19 and the fatality rate in COVID-19 patients with CVD is higher compared to other co-morbidities. Autopsies of COVID-19 patients reveal an infiltration of inflammatory mononuclear cells in the myocardium, confirming the role of the cytokine storm in response to COVID-19 infection. Cytokines are inflammatory immunologic proteins that are in the body to fight off infections but too many can result in an immune system gone wild. The body's own killer immune cells, in such an increased amount, can lead to organ failure and death. Currently, respiratory failure from acute respiratory distress syndrome (ARDS) is the leading cause of mortality of patients with COVID-19 and variants thereof and also suggesting potential causal mechanisms for the development of new cardiac pathologies and/or increasing damage of underlying CVDs in infected patients. Thus, the present invention provides for a novel approach to reduce the negative effects caused by direct cardiotoxicity through infecting the cells (cardiomyocytes).

[0030] The use of a NCB, and preferably zoledronic acid, as described in the present invention, rapidly alleviates the symptoms and signs related to COVID-19 and variants thereof. The negative effects of COVID-19 include acute myocarditis through a number of suspected mechanisms, including but not limited to, ACE2-mediated direct damage, hypoxia-induced myocardial injury, increased levels of D-dimers causing coagulopathy, cardiac microvascular damage, and cytokine release syndrome in treated patients. The reduction of these symptoms results in a substantial clinical improvement of critically ill patients, allows for a better management of the patient by the intensive care unit (ICU) team and most important reduces mortality of treated patients. A particular advantage of the proposed treatment of using a NCB is that it does not induce immunodeficiency in the patient, unlike other conventional therapies containing on steroids or other immunosuppressants. The preservation of a certain degree of immunocompetence in treated patients reduces the possibility of emergencies due to other opportunistic infections that are very common in intensive care.

[0031] Further the present invention provides for a composition and method using a nitrogen-containing bisphosphonate to reduce levels of D-dimers in a treated subject. Some important markers of organ dysfunction and coagulopathy found in subjects with Covid-19 includes higher levels of D-dimers. D-dimers are protein products of cross-linked fibrin degradation that are present in the blood of most healthy individuals but have been found in dangerous levels in subjects experiencing the effects of COVID-19 and other respiratory viral infections, including viral pneumonia due to influenza. Thus, the reduction of D-dimers is another advantageous effect of the present invention.

[0032] Still another indicator to be reviewed and analyzed is the level of troponins that are a group of proteins found in heart (cardiac) muscle fibers that regulate muscular contraction. Normally, troponin is present in very small quantities in the blood. However, when there is damage to heart muscle cells, troponin is released into the blood. The more damage there is, the greater the concentration in the blood. (3) As such, measuring the level of cardiac-specific troponin in the blood can help detect heart injury.

[0033] To date, there are no previous reports on the use of NCB against virus infections especially due to COVID-19, and particularly the capacity of zoledronic acid to reduce and/or inhibit the negative effects relating to myocardial injury and without causing immunodeficiency. Zoledronic acid has been previously used to provide advantageous effects to subjects with heart disease (4). There is further discuss of such treatments described in U.S. Pat. Nos. 9,867,838 and 9,949,992, the contents of which are included herein by reference.

[0034] However, in those previously discussed methods the subjects were not experiencing the negative effects of COVID 19 or a variant thereof, wherein the negative effects causing such myocardial injuries are due to acute respiratory distress syndrome and cytokines storms. As such, the present invention provides for a novel use of NCBs to address viral infections and the negative effects of myocardial injuries thereof.

[0035] For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to preferred embodiments and specific language will be used to describe the same.

[0044] The term “zoledronic acid,” as used herein, means to include the free acid itself, i.e., 1-hydroxy-2-(imidazol-1-yl)ethane-1,1-diphosphonic acid, as well as any pharmaceutically acceptable salts and hydrates thereof and solvates thereof formed from other solvents used for its crystallization. 1-hydroxy-2-(imidazol-1-yl)ethane-1,1-diphosphonic acid and its pharmacologically acceptable salts, hydrates and solvates are well-known from the literature. They can be prepared by procedures known in the art, such as described, e.g., in U.S. Pat. No. 4,939,130. See also U.S. Pat. Nos. 4,777,163 and 4,687,767. The contents of the latter three patents are hereby incorporated by reference in their entirety.

[0045] The term “cardiomyopathy” refers to those diseases of the heart muscle that make it harder for the heart to pump blood to the rest of the body. Cardiomyopathy as defined herein also includes myocarditis, also known as inflammatory cardiomyopathy. The term “infection-induced cardiomyopathy” refers to those diseases of the heart caused as the result of an infection. As used herein, the term “infection” refers to the invasion and multiplication of microorganisms, such as bacteria, viruses, parasites, protozoa, fungi, yeast, and the like in the body of a subject.

[0046] In some embodiments, the infection causes cardiomyopathy in the subject. In some embodiments, the cardiomyopathy is due to an infection selected from the group consisting of a viral infection, a yeast infection, a bacterial infection, a parasitic infection, a fungal infection, and combinations thereof. In some embodiments, the infection comprises a viral infection. In other embodiments, the viral infection comprises an infection caused by a coronavirus. In some embodiments, the viral infection comprises SARS, MERS, COVID-19 and variants thereof. In certain embodiments, the viral infection comprises COVID-19 or variants thereof.

[0047] As used herein, “treatment,” “therapy” and/or “therapy regimen” refer to the clinical intervention made in response to a disease, disorder or physiological condition manifested by a patient or to which a patient may be susceptible. The aim of treatment includes the alleviation or prevention of symptoms, slowing or stopping the progression or worsening of a disease, disorder, or condition and/or the remission of the disease, disorder or condition.

[0048] As used herein, the term “preventing” means minimizing or partially or completely inhibiting the development of infection-induced cardiomyopathy in a mammal at risk for developing infection-induced cardiomyopathy. Determination of whether infection-induced cardiomyopathy is minimized or prevented by administration of a bisphosphonate is made by known methods.

[0054] Variants of the COVID-19 may include changes in the amino acids found in the spike protein of the virus, but also in the ORF protein region. For example, the B.1.1.7 variant has a notable mutation N501 Y. Other mutations have been found to have more infective including A222V, E484K, S477N and K417N/T. As the virus spreads and more people are infected additional variants are inevitable

[0055] The term “functionally active analog,” as used herein, means compounds derived from a particular parent compound by straightforward substitutions that do not result in a substantial (i.e., more than 100x) loss in the biological activity of the parent compound, where such substitutions are modifications well-known to those skilled in the art, e.g., esterification, replacement of hydrogen by halogen, replacement of alkoxy by alkyl, replacement of alkyl by alkoxy, etc.

[0056] The bisphosphonate (e.g., a nitrogen-containing bisphosphonate such as zoledronic acid), is preferably used in the form of pharmaceutical compositions that contain a therapeutically effective amount of the bisphosphonate active ingredient optionally together with or in admixture with inorganic or organic, solid or liquid, pharmaceutically acceptable carriers which are suitable for administration.

[0057] The pharmaceutical compositions may be, for example, compositions for enteral, such as oral, rectal, aerosol inhalation or nasal administration, compositions for parenteral, such as intravenous or subcutaneous administration, or compositions for transdermal administration, e.g., passive or iontophoretic. Preferably, the pharmaceutical compositions are for intravenous administration. The pharmaceutical compositions may also be for direct intracoronary injection or elution from an intravascular or intracardiac device.

[0058] The particular mode of administration and the dosage may be selected by the attending physician taking into account the particulars of the patient, especially age, weight, lifestyle, activity level, hormonal status, e.g., post-menopausal, and bone mineral density as appropriate. Most preferably, however, zoledronic acid is administered intravenously and the dosage of the zoledronic acid may depend on various factors, including sex, age, weight and/or individual condition of the subject.

[0059] Normally the dosage is such that a single dose of a nitrogen-containing bisphosphonate such as zoledronic acid or salt or hydrate thereof, is from about 0.002 to about 20.0 mg/kg, preferably from 0.01 to 1 mg/kg, and more preferably from about 0.04 mg/kg to about 0.125 mg/kg. The term “mg/kg” means mg of drug per kg body weight of the subject. The dosage will be determined to correspond with the frequency of administering the compound.

[0060] In accordance with the present disclosure, the bisphosphonate is dosed at intervals of at least about once a month, every three months, six months, e.g., once every 180 days, or less frequently, conveniently once a year, or at any interval in between, e.g., once every 7, 8, 9, 10 or 11 months. The dose mentioned above, either administered as a single dose or in several partial doses, is preferably administered once per year (understanding, of course, that it may not be exactly one year to date but rather at yearly check-ups).

[0061] Formulations in single dose unit form contain preferably from about 1% to about 90%, and formulations not in single dose unit form contain preferably from about 0.1% to about 20% of the zoledronic acid active ingredient. Pharmaceutical preparations for enteral and parenteral administration are, for example, those in dosage unit forms, such as drages, tablets or capsules and also ampoules. They are prepared in a manner known per se, for example, by means of conventional mixing, granulating, confectioning, dissolving or lyophilizing processes.

[0062] For example, pharmaceutical preparations for oral administration can be obtained by combining the active ingredient with solid carriers, where appropriate granulating a resulting mixture, and processing the mixture or granulate, if desired or necessary after the addition of suitable adjuncts, into tablets or drage cores. Suitable carriers are especially fillers, such as sugars, for example, lactose, saccharose, mannitol or sorbitol, cellulose preparations and/or calcium phosphates, for example, tricalcium phosphate or calcium hydrogen phosphate, and also binders, such as starch pastes, using, for example, corn, wheat, rice or potato starch, gelatin, tragacanth, methylcellulose and/or polyvinylpyrrolidone and, if desired, disintegrators, such as the above-mentioned starches, also carboxymethyl starch, cross-linked polyvinylpyrrolidone, agar or alginic acid or a salt thereof, such as sodium alginate. Adjuncts are especially flow-regulating agents and lubricants, for example, silicic acid, talc, stearic acid or salts thereof, such as magnesium or calcium stearate, and/or polyethylene glycol. Drage cores are provided with suitable coatings that may be resistant to gastric juices, there being used, inter alia, concentrated sugar solutions that optionally contain gum arabic, talc, polyvinylpyrrolidone, polyethylene glycol and/or titanium dioxide, or lacquer solutions in suitable organic solvents or solvent mixtures or, to produce coatings that are resistant to gastric juices, solutions of suitable cellulose preparations, such as acetylcellulose phthalate or hydroxypropylmethylcellulose phthalate. Coloring substances or pigments may be added to the tablets or drage coatings, for example for the purpose of identification or to indicate different doses of active ingredient.

[0063] Other orally administrable pharmaceutical preparations are dry-filled capsules made of gelatin, and also soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The dry-filled capsules may contain the active ingredient in the form of a granulate, for example, in admixture with fillers, such as lactose; binders, such as starches; and/or glidants, such as talc or magnesium stearate, and, where appropriate, stabilizers. In soft capsules, the active ingredient is preferably dissolved or suspended in suitable liquids, such as fatty oils, paraffin oil or liquid polyethylene glycols, it being possible also for stabilizers to be added.

[0064] Parenteral formulations are especially injectable fluids that are effective in various manners, such as intra-arterially, intramuscularly, intraperitoneally, intranasally, intradermally, subcutaneously or preferably intravenously. Such fluids are preferably isotonic aqueous solutions or suspensions which can be prepared before use, for example, from lyophilized preparations which contain the active ingredient alone or together with a pharmaceutically acceptable carrier. The pharmaceutical preparations may be sterilized and/or contain adjuncts, for example preservatives, stabilizers, wetting agents and/or emulsifiers, solubilizers, salts for regulating the osmotic pressure and/or buffers.

[0065] Suitable formulations for transdermal application include an effective amount of the zoledronic acid active ingredient with carrier. Advantageous carriers include absorbable pharmacologically acceptable solvents to assist passage through the skin of the host. Characteristically, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the active ingredient of the skin of the host at a controlled and predetermined rate over a prolonged period of time and means to secure the device to the skin.

[0066] In another embodiment, the present disclosure relates to ensuring that the subject has an adequate level of Vitamin D before the administration of the bisphosphonate compound and specifically zoledronic acid. The level of Vitamin D can be easy determined by a simple blood test that determines the level of Calcidiol (25-hydroxyvitamin D). The unit dose of Vitamin D will be determined by the specific form, the number of days of administration, age and condition of patient, and level of determined Vitamin D deficiency. For example, cholecalciferol may in a unit tablet dose of from about 400 to 5000 IU or in intramuscular form from about 50,000 units/cc to 100,000 units/cc; egocalciferol in unit capsule dose of from about 400 to 50,000 IU; oral calcitriol in a dose from about 0.10 to about 1 mcg which can be administered at least once a day or in multiple administrations; calcidiol or doxercalciferol, both of which are vitamin D analogues may be administered in dose units of from about 300 to 2000 IU.

[0067] In yet another embodiment, the present disclosure relates to a formulation that includes a bisphosphonate (e.g., a nitrogen-containing bisphosphonate such as zoledronic acid), a form of Vitamin D and optionally calcium in an essentially homogeneous mixture, wherein a solution or solid unit dose can be administered in a single dose. The single dose can be administered daily, monthly or yearly, or at some intermediate interval depending on the bisphosphonate compound.

[0068] In some embodiments, the nitrogen-containing bisphosphonate is selected from the group consisting of pamidronate (APD, Aredia), neridronate (Nerixia), olpadronate, alendronate (Fosamax), ibandronate (Boniva), risedronate (Actonel), zoledronic acid (Zometa, Aclasta), cimadronate, clodronate, tiludronate, etidronate, piridronate, and/or functional derivatives and/or analogues and/or esters, and/or salts thereof. In certain embodiments, the nitrogen-containing bisphosphonate preferably comprises zoledronic acid.

[0069] In some methods, the dosage of a nitrogen-containing bisphosphonate is from about 30 μg/kg to about 125 μg/kg.

[0070] In some embodiments, the nitrogen-containing bisphosphonate is administered prior to the infection. In other embodiments, the nitrogen-containing bisphosphonate is administered at the time of infection. In another embodiment, the nitrogen-containing bisphosphonate is administered after the infection.

[0071] In some embodiments, the methods further comprise administering to the subject at least one other therapeutic agent(s) along with the composition and/or pharmaceutical compositions. In some embodiments, the at least one other therapeutic agent is selected from the group consisting of an anti-viral agent, an anti-fungal agent, an anti-bacterial agent, an anti-yeast agent, an anti-parasitic agent, an anti-protozoal agent, an anti-inflammatory agent (e.g., NSAIDS, Cox-2 inhibitors, corticosteroids, etc.), and combinations thereof. In one embodiment, the other therapeutic agent comprises an anti-viral agent. In some embodiments, the anti-viral agent is selected from the group consisting of chloroquine, hydroxychloroquine, remdesivir (Gilead Sciences), favilavir (National Medical Products Administration of China), fusogenix (EntosPharmaceuticals), ChAdOx1 (Univ. of Oxford), Gimsilumab (Roivant Sciences), AdCOVID (Altimmune), TJM2 (I-Mab Biopharma), AT-100 (Airway Therapeutics), TZLS-501 (Tiziana Life Sciences), OYA1 (OyaGen), BPI-002 (BeyondSpring), INO-4800 (Inovio Pharmaceuticals), NP-120 (Algernon Pharmaceuticals), APNO1 (APEIRON Biologics), mRNA-1273 (Moderna), Avian Coronavirus Infectious Bronchitis Virus (IBV) vaccine (MIGAL Research Institute), TNX-800 (Tonix Pharmaceuticals), Btilacidin (Innovation Pharmaceuticals), Recombinant subunit vaccine (Clover Biopharmaceuticals), leronlimab (CytoDyn), Linear DNA Vaccine (Applied DNA Sciences), BXT-25 (BIOXYTRAN), INO-4700 (Inovio), Actemra (Roche), Galidesiver (Biocryst Pharma), REGN3048-3051 (Regeneron), SNG001 (Synairgen Research), Aminoboost (lattice Biologics), and the like.

[0072] In some applications, it may be advantageous to utilize the active agent in a “vectorized” form, such as by encapsulation of the bisphosphonate active agent in a liposome or other encapsulant medium, or by fixation of the active agent, e.g., by covalent bonding, chelation, or associative coordination, on a suitable biomolecule, such as those selected from proteins, lipoproteins, glycoproteins, and polysaccharides.

[0079] Statistical Analysis

[0080] NCB exposure is defined as prescription of relevant NCB within 3 years prior to COVID-19 diagnosis (Table 1). To control for non-random assignment to NCB prescription, the propensity (probability) for prescription is calculated and used as a stratification variable. Generally, the estimate of the propensity is a large model, containing numerous predictors including patient demographics, provider preferences, medical comorbidities, and concurrent medications (Table 4).

[0081] Conditional Logistic Regression model is employed to calculate risk of the composite outcome of death, ventilator use, and ICU admission, as well as the risk of death as the primary outcome. The independent variable of interest is NCB prescription (yes/no), as defined above. The propensity for NCB prescription defines the strata for each model. Expected confounding variables include age, gender, race/ethnicity, BMI, diabetes among other underlying medical comorbidities, and medical treatments provided (Table 3). Because of the increasing understanding of COVID-19 disease and treatment, the proposed confounding variables represent the minimum set of variables to be used. The general model can be represented as:

[00001]$\mathrm{logit}\left(\mathrm{Outcome}\right)=\log \frac{P\left(\mathrm{Outcome}\right)}{1-P\left(\mathrm{Outcome}\right)}={\beta }_0+{\beta }_1\left(\mathrm{NCB}\mathrm{Prescription}\right)+.Math.{\beta }_i{X}_i$

[0082] where X.sub.i represent the confounding independent variables which are thought to relate linearly with the logit(Outcome). Primary analysis is stratified by NCB propensity score quintile; sensitivity analyses using direct matching by propensity score will be performed.

SUMMARY

[0083] statistics (average effect, S.E., 95% CI) across the strata for overall effect will be calculated using standard meta-analytic techniques.

[0086] Results

[0087] Nitrogen-containing bisphosphonate to Treat Hospitalized Patients With COVID-19 (SARS-CoV-2) with a finding that nitrogen-containing bisphosphonates are associated with lower ventilator use and ICU admission among older adults with COVID-19.

[0088] Background: Widely used in the treatment of osteoporosis, nitrogen-containing bisphosphonates (NCBs) have been associated with reduced mortality and cardiopulmonary morbidity among older adults. Prior preclinical studies suggest NCB may mediate inflammation and subsequent fibrosis. Containing on these prior studies, it is hypothesized that NCPs could reduce ventilator use and ICU use admission among COVID-19 patients.

[0089] Methods: a retrospective cohort analysis of administrative data was conducted among 57 National Patient-Centered Clinical Research Network studies (PCORNets DataMarts) through September 2020.

[0090] Individuals age>50 years with a diagnosis or positive laboratory test for COVID-19 during the study period were identified. Use of nitrogen-containing bisphosphonates (NCB) was defined as a prescription for Alendronate or Zoledronic acid within 3 years prior to the index COVID-19 diagnosis.

[0091] The outcome of interest was ventilator use or ICU admission.

[0092] Results: Of 62,214 COVID-19 subjects identified during the study period, 1,014 were previously prescribed an NCB. There were 185 subjects who were previously prescribed Zoledronic acid. The mean age of the cohort was 65.1 years, with 51% female. The majority of subjects were White (44%), with 26% Black and 21% Hispanic. Among those prescribed an NCB, there was a decrease in the risk of ventilator use or ICU admission, but the result was not statistically significant. (RR 0.87, 95% CI: 0.72-1.04).

[0093] However, In subgroup analysis restricting to subjects age 60-89 years, prior NCB was associated with significant decrease in ventilator use or ICU admission (RR 0.72, 95% CI: 0.59-0.88).

[0094] Conclusion: Among older COVID-19 patients between the age of 60 and 89 years, prior exposure to NCB was associated with a 28% reduction in ventilator use and ICU admission. These results suggest a prophylactic role of NCBs in mitigating the severity of COVID-19.

[0095] Because many patients hospitalized with COVID-19 infection have significant inflammation in the lungs and heart, thus it is believed, in light of the above data, that patients who have received a course of NCB treatment within the last 3 years will have a 15-25% improvement in their rate of survival after hospitalization compared to patients who have not had exposure to NCB therapy.
