DETAILED DESCRIPTION

[0049] The disclosure relates to a method for producing an autologous anti-inflammatory/anti-catabolic composition that produces IL-1ra, TIMP 1 and TIMP 2 in sufficient quantities for therapeutic use when stored at room temperature for at least about 3.5 hours to about 6 hours or more at a temperature of about 20° C. to about 40° C.

[0050] The disclosure also relates to a method for producing an autologous composition comprising the autologous anti-inflammatory/anti-catabolic composition in combination with a regenerative autologous platelet-rich plasma (PRP) composition with serum enriched by bioactive proteins having a anti-inflammatory/anti-catabolic, proliferative, tissue remodeling and regenerative effects. With respect to the autologous composition referred to herein, the autologous anti-inflammatory/anti-catabolic composition is an anti-inflammatory/anti-catabolic component of the autologous composition whereas the regenerative autologous platelet-rich plasma (PRP) composition is a regenerative component of the autologous composition.

[0051] Such a composition typically includes the following therapeutically active proteins: IL-1ra, IL-4, IL-10, IL-13, PDGF, TGF-β and VEGF.

[0052] IL-1ra is secreted by monocytes, adipocytes and epithelial cells. It is known that therapeutically effective concentrations of this protein are achieved by incubating human monocytes from healthy human subjects at about 37° C. for about 24 h. It has now been discovered that for individuals who have osteoarthritis, that therapeutically effective concentrations of IL-1ra and TIMPs are achieved by incubating or storing human blood admixed with sodium citrate at a temperature of about 20° C. to about 40° C. for about 3.5 hours to about 6 hours or more.

[0053] IL-4, 10, 13, PDGF, TGFβ are included in the content of platelets and-granules and are delivered in the PRP component. IL-4, 10, 13 come from white blood cells. PDGF is produced by platelets and TGFβ is released by platelets and some T cells. Employing the regenerative effect of the mentioned proteins leads to generation of a potent bio-active autologous product. Thus, a combination of fresh-prepared PRP as a source of regenerative biological factors and anti-inflammatory cytokines and growth factors, and the anti-inflammatory component comprising stored autologous serum as a source of IL-1 inhibitor provides a powerful and cost-effective autologous therapeutic agent for treatment of degenerative conditions like osteoarthritis, chronic tendinosis and chronic muscle tears as well as skin inflammatory disorders.

[0054] As used herein, “treatment” includes palliative treatment, wherein pain and/or inflammation is reduced in the subject.

[0055] Terms of degree such as “substantially”, “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. These terms of degree should be construed as including a deviation of at least ±5% of the modified term if this deviation would not negate the meaning of the word that it modifies.

[0056] The described method for producing an autologous composition for the treatment of osteoarthritis, chronic tendinosis and chronic muscle tear as well as skin inflammatory disorders preferably comprises the step of collecting a mammal's autologous physiological fluid, preferably blood by an aseptic technique. Preferably, the mammal is a human. However, the compositions and methods hereof are also suitable for a wide range of veterinary applications, for example for the treatment of horses, dogs and camels.

[0057] The site of venipuncture and the surface of the collection tubes may be cleaned with a 2 percent tincture of iodine solution. Before any cleansing of the site is begun, the patient may be asked about any allergy to iodine. Alternatively, the site of venipuncture and the surface of the collection tubes may be cleaned with a solution of 2% chlorhexidine gluconate in 70% isopropyl alcohol solution. The tube covers are cleaned with 70% alcohol solution also to avoid possible contamination before blood collection.

[0058] The autologous anti-inflammatory/anti-catabolic composition is preferably prepared by incubating or storing autologous physiological fluid, preferably blood from a mammal, preferably a human admixed with sodium citrate, at room temperature of preferably about 20° C. However, the blood admixed with sodium citrate can be incubated or stored at temperatures of from about 20° C. to about 40° C. with acceptable results.

[0059] The blood admixed with sodium citrate is incubated or stored preferably for about 3.5 hours to about 12 hours at about 20° C. for IL-1ra extracellular enrichment and preferably for the production of TIMPs. The blood admixed with sodium citrate is incubated or stored most preferably for about 3.5 hours to about 6 hours at about 20° C. However, the blood admixed with sodium citrate can be stored for longer than 12 hours and at temperatures of from about 20° C. to about 40° C. with acceptable results, as mentioned above.

[0060] A therapeutically effective amount of citrate in the form of sodium citrate, is added to preferably a sterile glass tube or a polystyrene tube into which the blood is collected prior to incubation. The sodium citrate provided is preferably a 4% by weight solution of sodium citrate. An example of an acceptable 4% by weight solution of sodium citrate is Anticoagulant Sodium Citrate Solution USP provided by Baxter Corporation under DIN 00060313 issued by Health Canada, containing 4 g of sodium citrate dihydrate per 100 ml of solution. In a particularly preferred embodiment, the incubation can be in sterile glass tubes (Coviden) or polystyrene (BD) vacutainer tubes with no additives. Further provided in an embodiment is the incubation of an autologous physiological fluid, preferably blood, on a rocker platform (24 rpm) or in static conditions. Preferably incubation is carried out in static conditions.

[0061] Preferably, the storing of blood is in the presence of 0.64-0.72 mM Ca.sup.++ to facilitate IL-1ra production. It is possible and advantageous in a particularly preferred embodiment to dilute cultured blood with sterile calcium chloride solution containing 0.64-0.72 mM Ca.sup.++ in 9:1 proportion by adding the solution using a sterile syringe and needle directly to the tube with blood before the incubation (1 cc of the calcium chloride solution to 9 cc whole blood). An equal part of sterile air may be added to the sterile tubes containing the blood to expose the culture to atmospheric air for increasing IL-1ra production. In a particularly preferred embodiment, the air is passed through a 0.22 μm MillexGP filter using a sterile syringe and needle directly to the tube with the blood before the incubation.

[0062] The sodium citrate solution at a concentration of 4% by weight of sodium citrate is admixed with the blood prior to incubation preferably in a ratio of 9.5 parts of whole blood (9.5 cc):0.5 parts of the 4% by weight sodium citrate solution (0.5 cc).

[0063] The incubated admixture of blood and sodium citrate is then subjected to centrifugation to separate a supernatant component from the cellular fraction. The supernatant component is the resultant autologous anti-inflammatory/anti-catabolic composition. The centrifugation is carried out according to methods known in the art. Preferably, the centrifugation is carried out for about 10-20 minutes at about 4000-10000 rpm. Most preferably the centrifugation is carried out for 10 minutes at 4000 rpm.

[0064] After centrifugation, the supernatant is preferably filtered through a 0.25 μm filter. The supernatant can be combined with the regenerative autologous platelet-rich plasma (PRP) composition immediately or can optionally be divided into aliquots for future processing using a sterile technique. The procedure is carried out in a sterile environment (laminar flow hood with HEPA filters). Preferably, about three cc of the supernatant containing biologically active agents are carefully drawn by sterile syringe and needle. Prolonged storage of IL-1ra containing product can be accomplished by freezing aliquots at about −20° C. and storing for up to 18 months at about −70° C.

[0065] The preparation of the regenerative autologous platelet-rich plasma (PRP) composition involves drawing blood into vacutainer tubes. The blood is then mixed with an anticoagulant according to methods known in the art. The preferred anticoagulant of the present disclosure is sodium citrate. Most preferably, the anticoagulant is a 4% by weight sodium citrate solution. Preferably, the anticoagulant is provided in a 9.5 parts of whole blood (9.5 cc):0.5 parts of 4% by weight sodium citrate (0.5 cc) ratio. A person skilled in the art will appreciate that other anticoagulants such as acid citrate dextrose solution and heparin can be used as the anticoagulant in the preparation of the regenerative autologous platelet-rich plasma (PRP) composition.

[0066] The blood is then subjected to centrifugation according to methods known in the art, preferably for about 30 seconds, at about 7500 rpm, to isolate the PRP fraction. The PRP fraction obtained as a product of the centrifugation step is the autologous PRP composition. The centrifugation parameters are used in preferred embodiments for the PRP preparation as a part of the final product for the osteoarthritis and chronic tendinosis treatment and skin disorders. The autologous PRP composition is drawn by a sterile syringe and needle under sterile conditions. In a particularly preferred embodiment for the treatment of chronic tear, a leukocyte buffy coat fraction is added to the autologous PRP composition as an additional VEGF source in order to promote new blood vessel development in the affected site. The buffy coat layer and plasma is collected manually by sterile syringe and needle after whole blood centrifugation as set out above or using a commercially available Harvest SmartPrep system.

[0067] The autologous PRP composition is optionally activated by filtering autologous PRP composition from the syringe through a small pore filter which is preferably an about 0.25 μm filter and most preferably a 0.22 μm MillexGP filter.

[0068] A final product is prepared comprised of a 50/50 combination of anti-inflammatory and regenerative (activated PRP) compositions by mixing the anti-inflammatory/anti-catabolic composition with the platelet rich plasma composition to provide the autologous composition.

[0069] The above disclosure generally describes the present application. A more complete understanding can be obtained by reference to the following specific examples. These examples are described solely for the purpose of illustration and are not intended to limit the scope of the application. Changes in form and substitution of equivalents are contemplated as circumstances might suggest or render expedient. Although specific terms have been employed herein, such terms are intended in a descriptive sense and not for purposes of limitation.

[0070] The following non-limiting examples are illustrative of the present disclosure:

EXAMPLES

Example 1

[0071] FIG. 1 demonstrates a significant production of IL-1ra in the blood of three human patients diagnosed with bilateral knee osteoarthritis where the blood was drawn from the patients and stored at room temperature of about 20° C. for either 3.5 hours or 6 hours in the presence of sodium citrate. The data shown in FIG. 1 is based on average results from the three patients, the details of which are provided below.

[0072] FIG. 2 demonstrates a significant production of TIMP 1 and TIMP 2 in the blood of the three patients diagnosed with bilateral knee osteoarthritis where the blood was stored at room temperature of about 20° C. for either 3.5 hours or 6 hours in the presence of sodium citrate. The data shown in FIG. 2 is based on average results from the three patients, the details of which are provided below.

[0073] The results demonstrate a significant production of IL-1ra, TIMP 1 and TIMP 2 in the blood of three human patients diagnosed with bilateral knee osteoarthritis where the blood was stored in the presence of sodium citrate at room temperature of about 20° C. for either 3.5 hours or 6 hours.

[0074] This was an unexpected result as blood stored in the absence of sodium citrate had not been previously demonstrated to produce significant levels of IL-1Ra, TIMP 1 and TIMP 2 after 3.5 hours or 6 hours of incubation.

[0075] The data shown in FIGS. 1 and 2 was obtained from the patients in cases 1, 2 and 3 from example 2 below.

Example 2

[0076] Each patient was an individual diagnosed with bilateral knee osteoarthritis. For each patients, blood was collected in separate glass and plastic tubes containing sodium citrate. Each glass tube contained about 9.5 parts of whole blood (9.5 cc) and 0.5 parts of a 4% by weight sodium citrate solution (0.5 cc).

[0077] The glass tubes containing the patient's blood were stored for either 3.5 h or 6 h at about 20° C. The levels of IL-1ra, TIMP 1 and TIMP 2 in the blood of the patients were then measured. The results for the three patients mentioned above are shown in FIGS. 1 and 2.

[0078] The glass tubes and were then centrifuged for 10 min at 4,000 4rpm to isolate the anti-inflammatory component. After centrifugation, the anti-inflammatory component was filtered through a 0.25 μm filter.

[0079] The blood collected in the plastic tubes was used to prepare the regenerative PRP component. The plastic tubes were centrifuged immediately at about 7500 rpm and the regenerative component was collected to a sterile syringe. The regenerative component from the syringe was then filtered and thereby activated by passing through a 0.25 μm filter. The regenerative component was then immediately combined with the anti-inflammatory component that had been stored for either 3.5 h or 6 h at about 20° C.

[0080] A final autologous composition was obtained comprising a 50/50 combination of the anti-inflammatory and regenerative (activated PRP) components. In each case, the autologous composition was administered to the patient.

[0081] Each patient was assessed with the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire for assessing pain, stiffness, and physical function in patients with hip and/or knee osteoarthritis. A one-month post-injection preliminary analysis of the WOMAC questionnaire data showed a statistically significant improvement in each of the patients' pain, stiffness and daily activities as shown in FIGS. 3-6. A statistical analysis of Visual Analog Pain Scale (VAS) revealed a significant pain reduction in each of the patients, as also shown in FIGS. 3-6.

Example 4

[0103] Twenty-two patients were treated with the autologous composition of the present disclosure. Each patient was an individual diagnosed with bilateral knee osteoarthritis. For each patient, blood was collected in separate glass and plastic tubes containing sodium citrate. Each glass tube contained about 9.5 parts of whole blood (9.5 cc) and 0.5 parts of 4% by weight sodium citrate solution (0.5 cc).

[0104] The glass tubes containing the patients' blood in admixture with sodium citrate were stored for 6 hours at about 20° C. The glass tubes were then centrifuged for 10 min at 4,000 rpm to isolate the anti-inflammatory component. After centrifugation, the anti-inflammatory component was filtered through a 0.25 μm filter.

[0105] The blood collected in the plastic tubes was used to prepare the regenerative PRP component. The plastic tubes were centrifuged immediately at about 7500 rpm and the regenerative component was collected to a sterile syringe. The regenerative component from the syringe was then filtered and thereby activated by passing through a 0.25 μm filter. The regenerative component was then immediately combined with the anti-inflammatory component that had been stored for 6 hours at about 20° C.

[0106] For each patient, a final autologous composition was obtained comprising a 50/50 combination of the anti-inflammatory and regenerative (activated PRP) components. In each case, the autologous composition was administered to the patient.

[0107] The twenty-two patients were assessed with the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire for assessing pain, stiffness, and physical function in patients with hip and/or knee osteoarthritis. A one-month post-injection preliminary analysis of the WOMAC questionnaire data showed a statistically significant improvement in the patients' pain, stiffness and daily activities in patients treated with the autologous composition as shown in FIGS. 11b, 11c, and 11d respectively. A statistical analysis of Visual Analog Pain Scale (VAS) revealed a significant pain reduction in the patients, as shown in FIG. 11a.
