Allogeneic human plasma and platelet derived products and uses thereof

[0001] This application is a continuation application of International Application No. PCT/US25/17819 filed on Feb. 28, 2025, which claims the benefit of U.S. Provisional Application 63/559,536, filed Feb. 29, 2024, and U.S. Provisional Application 63/722,936, filed Nov. 20, 2024, the contents of each are hereby incorporated by reference.

[0002] Painful joint conditions are commonly occurring and debilitating with many different etiologies. These diseases and the symptoms of pain and reduced function can be due to problems with the bone, nerves and connective tissue. Orthopedic and nervous tissue injuries such as painful lumbar radiculopathy, osteoarthritis, tendon or ligament injuries (such as to the rotator cuff), nerve injury (such as carpal tunnel, spinal cord or other traumatic nerve injury), and chemotherapy-induced peripheral neuropathy cause pain and disability across many demographic groups (Centeno, J Exp Orthop. 2017 Nov. 25; 4(1):38; Peng B Y, et al., J Biomed Sci. 2023; 30(1):77; Peng Y, et al., P M R. 2023; 15(12):1643-1653; Kawabata S, et al., Int J Mol Sci. 2023; 24(8):7677; Zunino, G. et al., Society of Neuroscience. Nov. 11-15, 2023, Washington DC). In particular, low back pain is one of the highest burden of diseases, and in 2016 was the leading cause of disability-adjusted-life-years (DALY) in 2016 (Mokdad A H, et al., JAMA. 2018 Apr. 10; 319(14):1444-1472). Painful lumbosacral radiculopathy (PLSR) is a disease that typically involves compression of the lumbar spinal nerve root, and it can manifest in several ways such as weakness, pain, or numbness. Non-steroidal anti-inflammatory drugs (NSAIDs) are the first line of treatment, providing short-term pain relief (van der Gaag W H, et al., Cochrane Database Syst Rev. 2020 Apr. 16; 4(4):CD013581), but may increase the risk of developing chronic pain (Parisien M, et al., Sci Transl Med. 2022 May 11; 14(644):eabj9954C). Steroids are often used to treat PLSR, despite no proven efficacy and significant side effects, including bone loss and increased spinal fracture risks. Opioids are also used to manage PLSR, but do not treat the cause and have significant addictive potential.

[0003] Autologous preparations of platelet rich plasma and human platelet lysate has been shown to be a promising regenerative therapy, which is attributed to the presence of cytokines and growth factors. Platelet rich plasma and human platelet lysates may be used locally to treat orthopedic, tendon or nerve injuries. Autologous platelet lysate has been administered epidurally to treat PLSR and was shown to reduce lumbar radicular pain (Centeno, J Exp Orthop. 2017 Nov. 25; 4(1):38). While the results with the autologous platelets demonstrate the potential pharmacological activity of a regenerative medicine in PLSR, there is inherent variability in the process of preparing the platelet lysate. The biological activity and identity of the autologous preparation is unknown, and there may be variability in the potency between individuals.

It has been demonstrated that the methods described herein result in a composition derived from allogenic human plasma and platelets with a high concentration of both plasma proteins (e.g., albumin, globulins, and fibrinogen) and platelet proteins (e.g., PGDF-AB, PDGF-AA, and PDGF-BB). In some aspects of the disclosure, human plasma proteins are reduced in the composition while a high concentration of human platelet proteins is maintained.

In some aspects, the disclosure provides a composition wherein the concentration of human plasma and platelet derived proteins is greater than about 50 mg/mL.

[0187] In some aspects, the disclosure provides a composition comprising a high concentration of allogenic human plasma and platelet derived proteins having a viscosity which maintains both human plasma proteins and human platelet proteins at a site of injection (e.g., a viscosity of about 10 to about 40 cP or less than about 50 cP). As therapeutics generally diffuse from a site of injection, it is believed a high viscosity allows a high protein concentration composition of the disclosure to remain at the site of injection for a period of time sufficient to provide a therapeutic effect. In some aspects, the viscosity of a high protein concentration composition of the disclosure is reduced by for example, dilution, removal of some plasma proteins, and/or inclusion of viscosity modifiers, while maintaining a high total concentration of human plasma and platelet derived proteins.

[0188] In some aspects, the disclosure provides a composition comprising a high concentration of allogeneic human plasma and platelet derived proteins and citrate. Citrate acts as a stabilizer, cryoprotectant, and anticoagulant and is often added to blood-derived products. In some aspects, methods for generating the composition comprise using one or more buffers comprising citrate. In some aspects, methods for generating the composition comprise removing citrate through, e.g., buffer exchange.

[0189] In some aspects, the compositions of the disclosure having a high concentration of allogeneic human plasma and platelet derived proteins are formulated for epidural or intraarticular injection to treat orthopedic conditions. In some aspects, the compositions of the disclosure are used for treating pain. In some aspects, the compositions of the disclosure are used for treating orthopedic and nervous tissue injuries such as painful lumbar radiculopathy, osteoarthritis, tendon or ligament injuries (such as to the rotator cuff), nerve injury (such as carpal tunnel, spinal cord or other traumatic nerve injury), and chemotherapy-induced peripheral neuropathy. In some aspects, the compositions of the disclosure are used for treating ophthalmic conditions or diseases. In some aspects, the compositions of the disclosure are used for treating open wounds or traumatic injuries. In some aspects, the compositions of the disclosure are used for treating burn wounds.

[0190] Further, the disclosure is based in part on the discovery of a method for generating the compositions of the disclosure. As described herein, it has been demonstrated that a composition comprising concentrated allogeneic human plasma and platelet derived proteins is generated by processing platelet suspensions from one or more human donor subjects to extract and concentrate platelet proteins, while also removing unwanted cells (e.g., white blood cells), cell debris, and viruses.

Characterization of Composition

[0273] In some embodiments, the presence of platelet proteins and/or plasma proteins is determined by detecting protein levels. In some embodiments, the concentration of platelet and/or plasma proteins is determined by quantifying protein levels. In some embodiments, the total protein concentration of the allogeneic human plasma and platelet e derived product is determined using methods for detecting and quantifying proteins. Methods for detecting and quantifying proteins are known in the art and described herein, for example, western blot, CE-SDS, SDS-PAGE, immunosorbent assays, BCA, etc. In some embodiments, the presence of platelet proteins and/or plasma proteins is determined by SDS-PAGE. Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is used to obtain high resolution separation of complex mixtures of proteins that comprise allogenic human platelet concentrate. This method allows protein separation by mass. Allogenic human platelet concentrate samples are diluted in a sample buffer containing SDS which denatures protein-protein interactions and mask the proteins' intrinsic charge making them similar charge-to-mass ratios. When a current is applied, all SDS-bound proteins will migrate through a gel towards the positively charged electrode. The gel is stained using an intercalating dye, visualized, and analyzed using densitometry for gross evaluation of protein composition.

[0274] In some embodiments, the presence of platelet proteins and/or plasma proteins is determined by capillary electrophoreses sodium dodecyl sulfate (CE-SDS). Protein analysis by CE-SDS relies on separation of SDS-bound protein variants by a sieving matrix (i.e. polymer) in a constant electric field. This method yields higher resolution compared to SDS-PAGE and allows for identification and purity analysis of proteins.

[0275] In some embodiments, the presence or quantity of platelet proteins and/or plasma proteins is determined by ELISA. In some embodiments, the presence or quantity of platelet proteins and/or plasma proteins is determined by quantitative sandwich enzyme immunoassay. In a quantitative sandwich enzyme immunoassay, a first antibody is coated on the surface of the multi-well plate and used as a capture antibody to facilitate the immobilization of the antigen. A second antibody can be conjugated to facilitate the detection of the antigen.

[0276] In some embodiments, the presence or quantity of platelet proteins and/or plasma proteins is determined by Meso Scale Discovery (MSD) assays. MSD relies on the same principle as ELISA but requires electrochemiluminescent signals as a detection method.

[0277] In some embodiments, the presence and/or quantity of cytokines is determined with a cytokine panel. In some embodiments, the cytokine panel is evaluated via mass spectrometry. In some embodiments, the cytokine panel is evaluated via an immunosorbent assay (e.g., ELISA, cytokine arrays). A human cytokine array is a rapid, sensitive, and economic tool to simultaneously detect multiple cytokines. Carefully selected capture antibodies are spotted in duplicate on nitrocellulose membranes. The allogeneic human platelet concentrate/antibody mixture is first diluted and incubated with the Human Cytokine Array membrane. Any cytokine/detection antibody complex present is bound by its cognate immobilized capture antibody on the membrane. Following a wash to remove unbound material, Streptavidin-HRP and chemiluminescent detection reagents are added sequentially. Light is produced at each spot in proportion to the amount of cytokine bound.

[0278] In some embodiments, the presence of A2M is determined with an enzyme linked immunosorbent assay (ELISA). In some embodiments, A2M content is determined using a commercially available sandwich ELISA. In this assay, the antibody specific for A2M is bound to the solid phase or support. A composition of interest is contacted with the solid phase or support to extract the antigen (A2M) from the sample by formation of a binary solid phase antibody:antigen complex. After a suitable incubation period, the solid support is washed to remove any unbound substances. An enzyme-linked biotinylated-polyclonal antibody specific for human A2M is then added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution containing streptavidin-HRP is added to the wells and color develops in proportion to the amount of A2M bound in the initial step.

In some embodiments, a platelet suspension comprises plasma and platelet cells. In some embodiments, platelet suspensions are obtained from whole blood. In some embodiments, platelets are obtained from whole blood using the buffy coat or platelet-rich plasma (PRP) technique. In the “PRP method”, anticoagulated whole blood is centrifuged using a soft spin under conditions validated to segregate red blood cells (RBC) from the upper half containing a platelet and plasma mixture, so called PRP. Platelets are then concentrated by hard spin centrifugation with validated acceleration and deceleration curves. The platelet suspension is left stationary at room temperature and then the concentrate is resuspended in plasma. In the “buffy coat” method, anticoagulated whole blood is centrifuged using a hard spin with validated acceleration and deceleration curves to separate “cell-free” plasma on the top layer, a middle layer called buffy coat (BC) and a red blood cells (RBC) bottom layer. The BC layer is transferred to a satellite bag. A small quantity of plasma is returned to the BC layer and gently mixed before again being subjected to light spinning centrifugation with validated acceleration and deceleration curves.

[0428] In some embodiments, platelet suspensions are obtained from apheresis. In some embodiments, apheresis comprises an extracorporeal medical device used in blood donation that separates the platelets and returns other portions of the blood to the donor.

[1448] For the present disclosure to be more readily understood, certain terms are first defined below. Additional definitions for the following terms and other terms may be set forth through the specification. If a definition of a term set forth below is inconsistent with a definition in an application or patent that is incorporated by reference, the definition set forth in this application should be used to understand the meaning of the term.

[1449] As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Thus, for example, a reference to “a method” includes one or more methods, and/or steps of the type described herein and/or which will become apparent to those persons skilled in the art upon reading this disclosure and so forth.

[1450] The term “about” or “approximately” when immediately preceding a numerical value means a range (e.g., plus or minus 10% of that value). For example, “about 50” can mean 45 to 55, “about 25,000” can mean 22,500 to 27,500, etc., unless the context of the disclosure indicates otherwise, or is inconsistent with such an interpretation. For example, in a list of numerical values such as “about 49, about 50, about 55, . . . ”, “about 50” means a range extending to less than half the interval(s) between the preceding and subsequent values, e.g., more than 49.5 to less than 52.5. Furthermore, the phrases “less than about” a value or “greater than about” a value should be understood in view of the definition of the term “about” provided herein. Similarly, the term “about” when preceding a series of numerical values or a range of values (e.g., “about 10, 20, 30” or “about 10-30”) refers, respectively to all values in the series, or the endpoints of the range.

[1451] The terms “at least,” “less than” or “more than” prior to a number or series of numbers (e.g., “at least two”) is understood to include the number adjacent to the term “at least,” “less than” or “more than,” and all subsequent numbers or integers that could logically be included, as clear from context. When the term “at least,” “less than” or “more than” is present before a series of numbers or a range, it is understood that “at least,” “less than” or “more than” can modify each of the numbers in the series or range.

[1452] The term “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified unless clearly indicated to the contrary. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A without B (optionally including elements other than B); in another embodiment, to B without A (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

[1453] As used herein, the term “subject” refers to any subject, e.g., a human or a non-human mammal, for whom diagnosis, prognosis, or therapy is desired. The term “subject” may mean a human or non-human mammal affected, likely to be affected, or suspected to be affected with a disease. In aspects, a subject is a mammal. A mammal includes primates, such as humans, monkeys, chimpanzee, and apes, and non-primates such as domestic animals, including laboratory animals (such as rabbits and rodents, e.g., guinea pig, rat, or mouse) and household pets and farm animals (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals, such as wildlife, birds, reptile, fish, or the like.

[1454] As used herein, the term “pharmaceutical composition” is a formulation containing the compounds and compositions of the present disclosure in a form suitable for administration to a subject.

[1455] As used herein, the term “pharmaceutically acceptable” refers to those compounds, anions, cations, materials, compositions, carriers, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

[1456] As used herein, the term “pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes excipient that is acceptable for veterinary use as well as human pharmaceutical use. A “pharmaceutically acceptable excipient” as used in the specification and claims includes both one and more than one such excipient.

[1457] The terms “polypeptide” and “protein” are used interchangeably herein. The term “polypeptide” refers to a protein or peptide that typically contains or consists of at least 20, and preferably at least 30, such as at least 50 amino acids. The term “peptide” refers to an oligomer containing or consisting of at least 2 amino acids to about 19 amino acids.

[1458] The terms “purifying” and “purification” in all their grammatical forms relate to the act of (substantially) reducing/depleting contaminants from the desired allogeneic human plasma and platelet derived product and intermediates thereof (e.g., platelet extract).

[1459] The terms “concentrating” and “concentration” in all their grammatical forms relate to the act of (substantially) increasing the concentration of a desired protein or proteins (e.g., platelet proteins) in a composition.

Exemplary and optional steps in the method are described below, and exemplary methods are provided in Examples 2-9 and 31.

Obtaining Platelet Suspensions

[1642] Platelet suspensions are obtained from one or more human donor subjects e.g., 16-35 years old. Alternatively, platelet suspensions are obtained from one or more human donor subjects, e.g., 35-65 years old. Platelet suspensions are obtained from whole blood units, blood fractions, and/or plasma fractions. Alternatively, platelet suspensions are obtained from transfusable quality platelets. The platelets can be separated from whole blood using apheresis or appropriate centrifuge procedures. Whole blood or platelets are treated with suitable anti-coagulant (Sodium citrate, EDTA, phosphate).

Filtering

[1643] The white blood cells and red blood cells are removed from the platelet suspensions via filtration. The platelet suspensions are passed through a suitable filter included, but not limited to, polyvinylidene fluoride (PVDF), nylon, polyether sulfone (PES), polysulfone (PS), regenerated cellulose (RC), or Glass Fiber (GF) filters. The size of the filter ranges from 0.1 μm to 40 μm and occurs at temperatures between 1 and 37° C. The plasma and platelets can be diluted prior to filtration to prevent clogging.

Extracting Platelet Proteins

[1644] To extract platelet proteins from the platelets, the platelet suspensions are maintained under appropriate conditions. The platelet suspensions can be diluted before or during extraction. Exemplary methods for extracting platelet proteins are provided below. For each method, several parameters will be evaluated including, but not limited to, total protein concentration, quantity of gross particulates, osmolality, and the quantities of functional platelet and serum proteins.

Freeze-Thaw

[1645] An exemplary method for extracting platelet proteins is subjecting the platelet suspensions to at least one freeze-thaw cycle. A freeze-thaw cycle includes maintaining the platelet suspensions at about −80° C. and then about 37° C. Alternatively, a freeze-thaw cycle includes maintaining platelet suspensions at about −80° C. and then about 25° C. The resulting platelet extract can be stored at −80° C. until further processing.

Detergent-Buffer

[1646] An exemplary method for extracting platelet proteins is maintaining the plasma and platelets in a sufficient detergent-buffer. The platelet suspensions are incubated with one or more detergents under continuous mixing or rocking for between 10 minutes and 24 hours. Incubation temperatures range from 4 to 40° C. Exemplary detergent include, but are not limited to, Sodium dodecyl sulphate (SDS), Triton X-45, Triton X-100, Triton X-114, NP-40, Tween 20, Tween 80, CHAPS, and CHAPSO.

Osmosis

[1647] An exemplary method for extracting platelet proteins is maintaining the platelet suspensions under hyperosmotic or hypoosmotic conditions. Specifically, the osmolality in the surrounding fluid can be increased or decreased. The osmolality ranges from 0.01 to 1000 mOsm/kg. Salts, sugars, and buffers that are compatible with platelet suspensions are added to increase osmosis. The change in osmolality can drive water into the platelets, breaking the platelet membrane. Conversely, the change in osmolality can draw water out of platelets, shrinking the platelets so they release proteins.

Sonication

[1648] An exemplary method for extracting platelet proteins is subjecting the platelet suspensions to sonication. Specifically, the platelet suspensions are pulsed with high-frequency sound waves via ultrasonic bath or probe. The frequency is 5 to 30 kHz, the temperature is 2-8° C., the pulse time is 1-30 seconds, and the rest time is 10-60 seconds. The conditions are optimized to prevent protein degradation.

Electroporation

[1649] An exemplary method for extracting platelet proteins is subjecting the plasma and platelets to electroporation. Specifically, the platelet suspensions are pulsed with a high-voltage electrical pulse with defined magnitude and lengths ranging from 0.1-10 kV, 1-300Ω, and 1-100 F. Electrical pulsing occurs from about 1 to about 20 milliseconds. Salts, sugars, cationic polymers, anionic polymers, surfactants, and buffers compatible with the platelet suspensions will be used.

High Pressure/Microfluidics

[1650] An exemplary method for extracting platelet proteins is subjecting the platelet suspensions to high pressure. For example, platelet suspensions can be subjected to high pressure using microchannels at pressures ranging from 10,000 to 50,000 PSI. The platelet suspensions can be passed through the microchannels one or more times.

Purifying the Platelet Extract

[1651] After extracting the platelet proteins to generate a platelet extract, cell debris and aggregates are removed from the platelet extract to generate a purified platelet extract. Several methods can be used to purify the platelet extract including, but not limited to, micro-filtration, depth-filtration, and centrifugation. Exemplary methods are described below. For each method, the extract will be inspected for total protein concentration and successful removal of debris and aggregates.

Micro-Filtration

[1652] An exemplary method for purifying the platelet extract is micro-filtration. Specifically, the platelet extract is passed through a filter with a 0.2 μm or larger pore size at a flow rate ranging from 0.1 to 50 L/hour. Suitable filters include, but are not limited to, polyvinylidene fluoride (PVDF), nylon, polyether sulfone (PES), polysulfone (PS), regenerated cellulose (RC), or Glass Fiber (GF) filters.

Depth-Filtration

[1653] An exemplary method for purifying the platelet extract is depth-filtration. Specifically, the platelet extract is passed through a filter at a flow rate of between 0.1 to 50 L/hour. Suitable filters include, but are not limited to, cellulose, polypropylene, Diatomaceous earth (DE), or non-DE in stacked disks.

Centrifugation

[1654] An exemplary method for purifying the platelet extract is centrifugation. Specifically, the platelet extract is centrifuged at 50 to 50,000×g for about 1 to about 100 minutes at about 2 to about 25° C.

Viral Inactivation and Removal

[1655] Viruses are inactivated and removed from the platelet suspension, platelet extract or purified platelet extract. Viral inactivation and removal can occur before extraction, after extraction, during extraction, or before concentration. Viruses can be inactivated via known techniques including, but not limited to, heat treatment, pH treatment, UV treatment, and chemical treatment. Chemicals suitable for viral inactivation include b-propiolactone, riboflavin, sulfites, and caprylate. Known techniques to remove viruses include, but are not limited to, filtration, affinity chromatography, and ion exchange chromatography.

Concentrating the Platelet Proteins

[1656] After removal of cell debris and aggregates, the purified platelet extract is concentrated to generate the allogeneic human plasma and platelet derived product. Exemplary methods for concentrating the purified platelet extract are provided below.

Tangential Flow Filtration

[1657] An exemplary method for concentrating the purified platelet extract is tangential flow filtration (TFF). Specifically, the purified platelet extract is subjected to TFF to concentrate the platelet proteins with TFF modules that include, but are not limited to, cassettes, hollow fiber, and ceramic, mPES membranes, regenerated cellulose, mixed cellulose ester, stabilized cellulose, polysulfone (PS), polyethersulfone (PES), and low-protein binding membranes. The membranes have a molecular weight cutoff between 1 kDa and 60 kDa. Alternatively, the membranes have a molecule weight cutoff between 1 kDa and 1,000 kDa. The TFF system is conditioned with a suitable buffer to ensure proper wetting of the membrane and to remove any preservatives or storage solutions that may be present. The product mix feed is introduced into the TFF system. The pump generates a tangential flow across the membrane, allowing the solvent to pass through while retaining the target molecules. The flow rate ranges from 1 to 50 L/hour. As the feed solution flows across the membrane, water is driven through the membrane, creating a concentrated retentate on one side of the membrane. The retentate contains the concentrated target product, while the permeate (filtrate) contains the removed impurities and excess solvent/buffer. The TFF process is closely monitored for transmembrane pressure, flow rates, and concentration factors. These parameters are controlled to optimize concentration and prevent membrane fouling or clogging. The concentrated and diafiltrated product is collected as the final retentate. The product can then be further processed or formulated for the subsequent downstream processing steps. Several parameters will be evaluated including, but not limited to, total protein concentration, quantity of gross particulates, osmolality, and the quantities of functional platelet and serum proteins.

Centrifugal Filters

[1658] An exemplary method of concentrating the purified platelet extract is use of a centrifugal filter. A suitable filter includes, but is not limited to, regenerated cellulose. The filter has a molecular weight cut off is 10 kDa. The platelet extract is centrifuged at 3.000×g for 15 minutes.

Removal of Plasma Proteins

[1659] The method described herein can include removal of plasma proteins. The plasma proteins are removed resulting in concentrated platelet proteins with higher purity. Plasma proteins include, but are not limited to, albumin, immunoglobulin, and fibrinogen. Methods to remove plasma proteins include, but are not limited to, affinity columns, size exclusion columns, fibrinogen clotting with CaCl₂), and ion exchange chromatography. Plasma proteins can be removed before extraction, after extraction, before cell debris and aggregate removal, after cell debris and aggregate removal, before concentration, or after concentration.

Sterile Filtration

[1660] After obtaining the allogeneic human plasma and platelet derived product, the product can be sterile filtered. The product is filtered with sterilization-grade filters sized 0.22 μm or less. Suitable filters include, but is not limited to, polyvinylidene fluoride (PVDF), nylon, polyether sulfone (PES), polysulfone (PS), regenerated cellulose (RC), or Glass Fiber (GF) filters. If desired, the product can be filled in a suitable container and kept frozen or refrigerated, liquid or solid (e.g., lyophilized for long-term storage or used as a powder).

[1736] The thawed platelets were subjected to both hypo-osmotic and hyper-osmotic conditions. Three different hypo-osmotic conditions were evaluated, as detailed in Table 8. To subject platelets to hyper-osmotic conditions, 100 mM of citrate (pH 7.5) was added.

[1737]

Detergent

[1738] 0.6% Tween 20 (Polysorbate 20) was used to evaluate platelet extraction via detergent. The thawed platelets were diluted in a buffer comprising 100 mM citrate (pH 7.5) and 0.6% Tween 20.

Freeze/Thaw

The platelet pellets were washed with phosphate-buffered saline (PBS) and concentrated to one-tenth of the initial volume.

The platelet pellets were heated at 56° C. for 30 minutes in a dry bath and immediately frozen at −70° C. for at least one hour. The platelets were centrifuged at 104×g for 15 minutes at 4° C. to eliminate precipitates.

[1740] To evaluate the impact of the extraction conditions on soluble protein concentration, total protein was quantified using a bicinchoninic acid assay (BCA). The total protein concentration for each extraction method is outlined in Table 9.

[1741]

TABLE 9

[1742] Sodium dodecyl sulfate-polyacrylamide gel electrophoreses (SDS-PAGE) was performed to further evaluate the effects of extraction conditions on total soluble protein (Table 9, FIG. 10). diluted protein sample were mixed with 1:4 with sample loading buffer (Invitrogen) and heated at 70° C. for 10 min. Samples were then loaded (5-25 g total protein load) into precast NuPAGE 4-12% Bis-Tris 1.0 mm Minigel (Invitrogen). Then, 5 μL of Pre-stained SDS-PAGE Standards (Bio-Rad) were loaded in each gel run. Human serum albumin and immunoglobulin control were included as protein specific molecular mass control. Electrophoresis was performed at room temperature for approximately 45 min using a constant voltage (200V) in 1× solution of NuPAGE MES SDS running buffer (Invitrogen) until the dye front reached the end of the gel. The gel is stained with Simply Blue Stain (Invitrogen) for approximately 30 minutes and washed overnight prior to imaging. Using densitometry, human serum albumin and immunoglobulin composition is determined by weight by weight percentage. All of the extraction conditions resulted in comparable protein concentrations and compositions.

[1743] To assess the allogeneic human plasma and platelet derived product produced by the foregoing methods, i.e., Process 1 without viral clearance and formulated in sodium citrate and salt, PDGF content and function was determined in a low-concentration and a high-concentration product. The low-concentration product is the high-concentration product diluted in 100 mM citrate and 5 mM EDTA. PDGF content was also determined in the starting material of platelet suspension and purified platelet extract (i.e., before concentration). Specifically, the amount of PDGF was quantified using a commercially available sandwich enzyme linked immunosorbent assay (ELISA) from R&D Systems. The antibody specific for PDGF-BB was bound to the solid phase or support. Diluted allogenic human plasma and platelet derived product was used to extract the antigen (PDGF) from the sample by formation of a binary solid phase antibody:antigen complex. After a suitable incubation period, the solid support was washed to remove any unbound substances. An enzyme-linked polyclonal antibody specific for human PDGF-AA was then added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution was added to the wells and color develops in proportion to the amount of PDGF-AB bound in the initial step. The color development was stopped, and the intensity of the color was measured. Total PDGF-AB was determined via absorption and extrapolated from a PDGF-AB standard curve. The concentrations of PDGF are outlined in Table 10. These results indicate PDGF-AB concentration is increased after extracting platelet proteins from platelets (purified platelet extract) and after concentration of the purified platelet extract, indicating the methods described herein concentrate platelet proteins such as PDGF-AB.

The activity of PDGF is summarized in FIG. 11. These results indicate the function of PDGF was maintained during the process described herein for generating the allogeneic human plasma and platelet derived product.

[1746] To assess the allogeneic human plasma and platelet derived product produced by the foregoing methods, i.e., Process 1 without viral clearance and formulated in sodium citrate and salt, alpha-2-macroglobulin (A2M) content was determined using a commercially available sandwich enzyme linked immunosorbent assay (ELISA; Invitrogen). In this assay, the antibody specific for A2M was bound to the solid phase or support. Diluted allogenic human plasma and platelet derived product was diluted in 100 mM citrate and 5 mM EDTA and contacted with the support to extract the antigen (A2M) from the sample by formation of a binary solid phase antibody:antigen complex. After a suitable incubation period, the solid support was washed to remove any unbound substances. An enzyme-linked biotinylated-polyclonal antibody specific for human A2M was then added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution containing streptavidin-HRP was added to the wells and color develops in proportion to the amount of A2M bound in the initial step. The color development was stopped, and the intensity of the color was measured. Total A2M was determined via absorption and extrapolated from an A2M standard curve. The concentrations of A2M are summarized in Table 11.

[1748] To assess the allogeneic human plasma and platelet derived product produced by the foregoing methods, i.e., Process 1 without viral clearance and formulated in sodium citrate and salt, fibrinogen content was determined using a commercially available sandwich enzyme linked immunosorbent assay (ELISA; LSBio). A high concentration allogeneic human plasma and platelet derived product (i.e., ˜150 mg/mL total protein concentration) was used to evaluate fibrinogen content. The high concentration allogeneic human plasma and platelet derived product was prepared via extracting platelet proteins from platelet suspensions via freeze-thaw and concentrated via spin filters.

[1749] In the ELISA assay, the antibody specific for fibrinogen was bound to the solid phase or support. Allogenic human plasma and platelet derived product was diluted in buffer provided by the ELISA kit and contacted with the support to extract the antigen (fibrinogen) from the sample by formation of a binary solid phase antibody:antigen complex. After a suitable incubation period, the solid support was washed to remove any unbound substances. An enzyme-linked biotinylated-polyclonal antibody specific for human fibrinogen was then added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution containing streptavidin-HRP was added to the wells and color develops in proportion to the amount of fibrinogen bound in the initial step. The color development was stopped, and the intensity of the color was measured. Total fibrinogen was determined via absorption and extrapolated from a fibrinogen standard curve. The concentrations of fibrinogen are summarized in Table 12. Specifically, the amount of fibrinogen was determined for the starting material, i.e., a platelet suspension, and the allogeneic human plasma and platelet derived product produced by the methods described herein. These data show not only that fibrinogen is maintained in the allogeneic human plasma and platelet derived product, but that concentration is increased.

[1751] To assess the allogeneic human plasma and platelet derived product produced by the foregoing methods, i.e., Process 1 without viral clearance and formulated in sodium citrate and salt, cytokine content was determined. The human cytokine array (R&D Systems) is a rapid, sensitive, and economic tool to simultaneously detect 105 cytokines. Carefully selected capture antibodies have been spotted in duplicate on nitrocellulose membranes. The allogeneic human plasma and platelet derived product and antibody mixture was first diluted and incubated with the Human Cytokine Array membrane. Any cytokine/detection antibody complex present was bound by its cognate immobilized capture antibody on the membrane. Following a wash to remove unbound material, Streptavidin-HRP and chemiluminescent detection reagents were added sequentially. Light was produced at each spot in proportion to the amount of cytokine bound.

[1752] Of the 105 cytokines assessed, the following 96 were detected in allogeneic human plasma platelet protein samples (cytokines in bold align with expected composition): Adiponectin/Acrp30, IFN-gamma, CCL2/MCP-1, Angiogenin, IGFBP-2, CCL7/MCP-3, Angiopoietin-1, IGFBP-3 M-CSF, Angiopoietin-2, IL-1 alpha/IL-1F1, MIF, Apolipoprotein A1, IL-1 beta/IL-1F2, BAFF/BLyS/TNFSF13B, IL-1ra/IL-1F3, CCL3/CCL4, BDNF, IL-2, CCL20/MIP-3 alpha, CD14, IL-3, CCL19/MIP-3 beta, CD30, IL-4, MMP-9, CD31/PECAM-1, IL-5, Myeloperoxidase, CD40 Ligand/TNFSF5, IL-6, Osteopontin (OPN), Chitinase 3-like, IL-8, PDGF-AA, Complement Component C5/C5a, IL-10, PDGF-AB/BB, Complement Factor D, IL-11, Pentraxin 3/TSF-14, C-Reactive Protein/CRP, IL-12 p70, CXCL4/PF4, Cripto-1, IL-13, RAGE, Cystatin C, IL-15, CCL5/RANTES, Dkk-1, IL-16, RBP4, DPPIV/CD26, IL-17A, Relaxin-2, EGF, IL-18 BPa, Resistin, CXCL5/ENA-78, IL-19, CXCL12/SDF-1 alpha, Endoglin/CD105, IL-22, Serpin E1/PAI-1, EMMPRIN, SHBG, Fas Ligand, ST2/IL1, R4, FGF basic, IL-27, CCL17/TARC, KGF/FGF-7, IL-31, TFF3, FGF-19, IL-32 alpha/beta/gamma, TfR, Flt-3 Ligand, TGF-alpha, G-CSF, Thrombospondin-1, GDF-15, CXCL10/IP-10, TIM-1, GM-CSF, CXCL11/I-TAC, CXCL1/GRO alpha, Kallikrein 3/PSA, uPAR, Growth Hormone (GH), Leptin, VCAM-1, HGF, VEGF, ICAM-1/CD54, Lipocalin-2/NGAL, and Vitamin D BP.

[1753] To assess the step of concentrating platelet extract in the method of producing an allogeneic human plasma and platelet derived product, 1 bag of plasma platelets was split into 4 samples. The bags were initially thawed and then subjected to three cycles of freeze-thaw. Specifically, platelets were frozen for over an hour at about −60 to −80° C. To thaw, the platelets were placed in a 37° C. bath for 30 minutes. The platelets were centrifuged for 15 minutes at 3,000×g. The platelets were then sterile filtered with a 0.2 μm polyethersulfone (PES) vacuum filter. One sample was diluted 2-fold in 100 mM citrate buffer at pH 7.5. One sample was diluted 2-fold in in Dulbecco's phosphate buffered saline (DPBS). Two samples remained undiluted (“water”). The platelets were then concentrated with 10 kDa MWCO Amicon spin filters. The concentration of total soluble protein was quantified via BCA and viscosity was quantified via a capillary viscometer. The total soluble protein and viscosity are outlined in Table 13. Without being bound by theory, compositions with higher viscosity allow for localized injection and positive pressure to accelerate healing.

[1755] To evaluate the effects of sterile filtration on total soluble protein, platelets were lysed via freeze-thaw as described in Example 3. The platelet proteins were filtered with 0.2 μm nylon and polyethersulfone (PES) filters. The total soluble protein of two samples filtered with nylon filters was quantified via BCA (Table 14). To evaluate total protein of samples filtered with PES filters, SDS-PAGE was run (FIG. 12). Samples were taken after extraction and after sterile filtration. Samples were compared to pure IgG and human serum albumin to evaluate the major proteins within the soluble fraction.

[1757] To evaluate the immunogenicity of an allogeneic human plasma and platelet derived product, an in vitro screen is used (see Cohen, S. et al., (2021). Immunogenicity risk assessment for biotherapeutics through in vitro detection of CD134 and CD137 on T helper cells. Briefly, donor peripheral blood mononuclear cells (PBMCs) are incubated with AHPPDP or KLH (keyhole limpet hemocyanin) and cultured for 42-48 hours. The PBMCs are washed and analyzed by fluorescence-activated cell sorting (FACS). The CD4+ T cell fraction of the PBMCs is evaluated for expression of CD134 and CD137. Enhanced levels of CD134 and/or CD137 indicate high immunogenic potential. KLH represents a positive control for the assay.

[1758] To assess the potential immunogenicity of AHPPDP, an in vitro assay was used to compare the CD4+ T cell response of human donor peripheral blood mononuclear cells (PBMC) to AHPPDP, keyhole limpet hemocyanin (KLH), and commercially available intravenous immunoglobulin (IVIg; Gammagard®). In the assay KLH was used as a positive control, and IVIg was chosen as an allogenic blood product to compare against AHPPDP as it had the potential for similar contaminants. The AHPPDP composition utilized in this assay (CUR-2401-6L-SEP24) was generated by the method set forth in Example 31, FIG. 26, including concentration of platelet proteins through buffer exchange including removal of citrate and formulating in a suitable buffer. The stimulation index (SI) was calculated for each compound (Table 15), which is defined as the ability of the biotherapeutic to increase the fraction of live CD4+ cells that were positive for either CD134 or CD137 compared to the fraction of cells positive for these markers in formulation buffer samples.

[1759]

[1760] In this assay, AHPPDP was tested against 10 healthy donor samples (including Rh positive and negative, and O, A, and AB blood types). The results, provided in FIG. 20, demonstrate KLH elicited the highest SI score, as expected for a strongly immunogenic protein commonly used as a positive control in immunoassays. For 9 of 10 donors tested, AHPPDP had a similar or lower SI score than IVIg. Only Donor 8 had a higher response to AHPPDP than IVIg and had an extremely high response to KLH. Donor 2 had a very strong response to KLH and IVIg, and lower response to AHPPDP.

[1761] The results indicate the immunogenicity of AHPPDP may be similar to other blood-derived products, such as IVIg, and does not strongly activate T-cells.

[1762] To evaluate the functional activity of allogeneic human plasma and platelet derived product, growth factors are assessed. Reporter cell lines are contacted with the allogeneic human plasma and platelet derived product and the levels of growth factors are quantified. Growth factors are assessed with commercially available kits. For example, EGFR (e.g., Human EGFR1 Report Assay Kit, Indigo Biosciences), TGF-β (e.g., Human Transforming Growth Factors Beta Receptors I/II Report Assay System, Indigo Biosciences), VEGF (e.g., VEGF Bioassay, Promega), and PDGF (e.g., Platelet-Derived Growth Factor Receptors a and R Reporter Assay System, Indigo Biosciences) are evaluated.

[1763] To evaluate whether the allogeneic human plasma and platelet derived product induces an anti-inflammatory response, an in vitro screen is used (see Singh, U., et al., 2005). Development of an in vitro screening assay to test the anti-inflammatory properties of dietary supplements and pharmacologic agents. Clinical chemistry, 51(12), 2252-2256.). Briefly, the monocytic cell line, THP-1, which is known to produce proinflammatory cytokines in response to lipopolysaccharide (LPS) stimulation, is utilized. THP-1 cells are grown in RPMI supplemented with fetal bovine serum (FBS) until they reach 70% confluency. THP-1 cells are pre-treated with allogeneic human plasma and platelet derived product for 1 hour. The cells are then contacted with 50 μg/L LPS for 4 hours. The supernatants are harvested and IL-1β, TNF-α, and IL-6 levels are quantified via enzyme-linked immunosorbent assays (ELISAs) and reported as pg/mg.

[1764] To investigate the feasibility and tolerability of epidural dosing of the allogeneic human plasma and platelet derived product, Sprague-Dawley rats is evaluated. On Day 1, 4-6 hours prior to treatment, the rats is observed. Each animal is administered a dose of vehicle (control) or the allogeneic human plasma and platelet derived product via a single epidural administration on Day 1. The animals are evaluated daily following treatment until euthanasia. Body weights are recorded prior to treatment and on Days 2, 3, 4, and prior to euthanasia. Interim blood is collected on Day 2 via tail vein/saphenous. 300 μL of blood samples is processed to serum and stored at nominally −70° C. until pharmacokinetic analysis.

[1765] Animals are euthanized via CO₂. A maximum obtainable volume (MOV) of whole blood samples is collected. At least 200 μL of whole blood is collected into EDTA tube and stored cold until CBC and coagulation analysis. The remaining blood sample is processed to serum and stored in aliquots. Aliquots are stored at nominally −70° C. until comprehensive chemical analysis. Whole blood and serum is evaluated.

[1766] Following exsanguination, animals undergo cardiac perfusion with saline. In brief, whole body intracardiac perfusion is performed by inserting 23/21-gauge needle (or appropriate) attached to 10 mL syringe (or appropriate) containing saline set into the lumen of the left ventricle for perfusion. The right atrium is incised to provide a drainage outlet for perfusate. Gentle and steady pressure is applied to the plunger to perfuse the animal after the needle is positioned in the heart. Adequate flow of the flushing solution is ensured when the exiting perfusate flows clear (free of visible blood) indicating that the flushing solution has saturated the body, and the procedure is complete.

[1767] To investigate the effect of an allogeneic human plasma and platelet derived product on neuropath pain, an in vivo mouse model is used. Neuropathic pain is characterized by abnormal sensitivity to stimuli. Chemotherapy Induced Neuropathic Pain (CINP) is induced in mice by treating mice with paclitaxel for 5 days. Allogeneic human plasma and platelet derived product or control is injected into mice on Day 6 and 7. Response to cool allodynia is assessed prior to treatment with paclitaxel and prior to and after treatment with AHPPDP or control. Cytokine levels, neurofilament light chain and histological markers of inflammation are assessed during treatment and after necropsy on Day 14.

[1768] To investigate the efficacy of allogenic human platelet and plasma derived product (AHPPDP) on arthritis in knees, Sprague Dawley rats were used. Arthritis was induced by a single intra-articular (IA) injection of complete Freund's adjuvant (CFA) as previously described (Noh A S M, et al. PLoS One. 2021 Dec. 8; 16(12):e0260423. doi: 10.1371/journal.pone.0260423). Specifically, CFA was injected into the right knee of adult male Sprague Dawley rats (n=4/group). A composition comprising AHPPDP, referred to as “Composition E26h” was prepared based on the methods disclosed herein. Specifically, Composition E26h was prepared as outlined in Process 1 above (Example 2, FIG. 1), without Step 5 (viral clearance). Further the platelet proteins were concentrated through buffer exchange including removal of citrate and formulating in a suitable buffer. Composition E26h was injected into the IA space of the right knee on Days −3, −1, and 2 relative to CFA injection. Buffer as used as the vehicle. Protein concentrations of Composition E26h and vehicle are set forth in Table 16.

[1770] On Day 1, while under light isoflurane anesthesia, all rats received either 50 or 100 μg (50 and 100 μL, respectively) of CFA by a single IA injection into the right knee according to Table 17. Body weights were recorded prior to CFA induction on Day −3 and daily thereafter until study termination on Day 7. Detailed clinical observations were conducted beginning on Day −3 prior to treatment and once daily thereafter until the end of study on Day 7. Both left and right knees were measured using calipers performed prior to CFA induction on Day −3 and daily thereafter. All rats were terminated on Day 7.

[1772] Following euthanasia, rats underwent cardiac perfusion with saline. In brief, whole-body intracardiac perfusion was performed by inserting 23/21-gauge needle attached to 10/20/50 mL syringe containing saline set into the lumen of the left ventricle for perfusion. The right atrium was incised to provide a drainage outlet for perfusate. Gentle and steady pressure was applied to the plunger to perfuse the rat after the needle was positioned in the heart. Adequate flow of the flushing solution was ensured when the exiting perfusate flowed clear (free of visible blood) indicating that the flushing solution saturated the body, and the procedure was complete.

[1773] Right knees from all rats and one left knee from one animal per group were decalcified, embedded in paraffin, sectioned, and stained with hematoxylin and eosin (H&E) to observe inflammation and Saf-O to evaluate proteoglycan and cartilage at the articular surface.

[1774] Body weight changes were generally comparable across treatment groups. Minimal (<5%) or no decrease was observed in group means across treatment groups, and decreases were generally more apparent on the day following CFA induction. One rat in Group 1 lost between 10-15% body weight on Days 5-7. There were no abnormal observations for Groups 1-4. Knee widths were similar across all groups prior to CFA induction on Day −3 to Day 1. On Day 2 following CFA induction, knee widths substantially increased in all groups indicating swelling. Rats were observed to not bear weight on the swollen right hind limb. On Days 3 and 4, groups treated with vehicle and 50 or 100 μg CFA had larger knee widths than groups treated with Composition E26h and 50 or 100 μg CFA. Knee widths for the group administered Composition E26h and 100 μg CFA had greater widths than the group administered the same dose of Composition E26h and 50 μg CFA. The group administered Composition E26h and 50 μg CFA had the lowest knee widths than all other groups. By Day 5, no differences in knee widths were observed across treatment groups (FIG. 13A-13B).

[1775] Intra-articular injection of 50 or 100 μg CFA into the right knee of Sprague Dawley rats induced marked inflammation 24 hours after injection, which persisted for 3 days, and then subsided to baseline levels by Day 5 as assessed by knee width measurements. Repeated intraarticular injection of Composition E26h appeared to have reduced knee widths relative to vehicle during the period of marked CFA-induced knee inflammation. On Day 2 there were no apparent differences in inflammation between groups treated with vehicle or Composition E26h On Day 3, there was a reduction in the swelling in the AHPPDP-treated groups relative to the vehicle groups. These results show, intra-articular injection of a composition comprising AHPPDP reduces inflammation and treats symptoms of arthritis in the knee.

[1776] The purpose of this study was to evaluate the effect of a composition comprising AHPPDP on cool allodynia in an acute chemotherapy-induced mouse model of paclitaxel-induced peripheral neuropathy (PIPN). A composition comprising AHPPDP was prepared as described in Example 23. A low dose (Composition F20f) and a high dose (Composition F20d) were prepared.

[1777] Adult male C57BL6/J mice were administered vehicle (n=10) or Composition F20f/F20d (n=15/dose group) intravenously (IV) under isoflurane anesthesia once on Day 6 and on Day 7 according to the experimental design presented in FIG. 14. Protein concentrations of the compositions and vehicle are set forth in Table 18.

[1779] Paclitaxel 15 mg/kg/day was administered intraperitoneally (IP) once daily to mice in Groups 2, 3, and 4 for 5 consecutive days (Table 19 and FIG. 14). Group 1 received an IP injection of the paclitaxel vehicle as the control.

[1781] Body weights were assessed prior to group assignment and daily during administration of the test articles set forth in Table 18. The welfare of the animals was checked at least daily by trained personnel and supervised by a veterinarian when warranted by clinical signs or other welfare-related changes.

Acetone Cooling Test for Allodynia:

[1782] Before subjecting the mice to the baseline acetone cooling test (ACT), they were pre-handled for 2 minutes on two consecutive days in their maintenance room with the purpose of decreasing false oversensitivity. Prior to testing, mice were allowed to acclimate to the testing room for 30-60 minutes.

[1783] The ACT was conducted by first placing the mice into individual Plexiglas chambers (i.e., von Frey chambers). The animals were allowed to acclimate in the test chambers for approximately an additional 30 minutes (±15 minutes, depending on their behavior). Test chamber habituation was deemed sufficient when the mice have explored the surroundings, groomed, and settled down. Testing was not performed while the animal was grooming, sleeping, urinating or defecating.

[1784] To produce a cooling sensation, a 10-15 μL of acetone spray was applied onto the medial area of the plantar hind paw using 0.5 mL syringes. Acetone application was done from close distance to the paw without touching the skin.

[1785] Responses of each animal to acetone were monitored for 20 seconds, and the score was given based on the following four-point scale:

• • [1786] 0=Short response to acetone, but doesn't stay scared after the first reaction OR reacts once more after acetone reaction.
  • [1787] 1=Two to three quick withdrawals, flicks, licks or stamps of the paw. Duration of the reaction is either 1 sec/reaction OR only one, but prolonged reaction (e.g. tremor) or it's duration is 3-5 sec.
  • [1788] 2=Repeated (4-5) short withdrawals, flicks, licks or stamps of the paw. Duration of the reaction is either 1 sec/reaction OR only one, but prolonged reaction, maximum of 10 sec.
  • [1789] 3=Notably prolonged or continuous (>5) withdrawals, flicks or licks of the stimulated paw. Duration of the reaction is either 1 sec/reaction OR only one, but prolonged reaction, minimum of 10 sec.

[1790] During each 20-second trial, the responses were tallied, and the score (0-3 points) given after the trial. A total of 3 trials (altogether 60 seconds) were performed on each paw with a minimum interval of 5 minutes between trials. The obtained three individual scores were added to obtain a single score over a cumulative period of 60 seconds. Thus, for one test, the minimum score of one paw was 0, while the maximum possible score was 9. To accomplish a result value for a mouse at a certain test timepoint, the total scores obtained for the left and right paws were averaged.

Blood Collection for Cytokine Analysis:

[1791] Blood (up to 100 μL) was collected on Day 5 (2 hours following paclitaxel and ACT) and Day 8 (following ACT) from the saphenous vein and processed to plasma. Plasma was analyzed using a Luminex multiplex assay for IL-6, IL1-β, IL-10, TNF-α, and IFN-7 for Groups 2 and 4 only.

Terminal Procedures:

[1792] Mice were euthanized with 180 mg/kg pentobarbital followed by exsanguination and transcardiac perfusion with ice cold heparinized (heparin 2.5 IU/mL) saline following with 4% paraformaldehyde. The cervical, thoracic, and lumbar segments of the spinal cord and left sciatic nerve were collected and fixed 24 hours in 4% paraformaldehyde at 4° C., then embedded in paraffin. Processed samples were held for potential future analysis.

Results:

[1793] Mice administered paclitaxel (Groups 2, 3, and 4) showed body weight loss concurrent with the onset of paclitaxel dosing and began weight gain on study Day 10. Mean group weights were significantly lower in Groups 2, 3, and 4 on Days 5 through 13 when compared to Group 1, which received paclitaxel vehicle on Days 1 through 5 and AHPPDP vehicle on Day 6 and 7.

[1794] Some mice in Groups 2, 3, and 4 showed transient clinical signs after treatment including piloerection, unkempt coat, and/or hunched posture following vehicle or AHPPDP. These observations were more severe in the vehicle group. With the exception of mortality described below, clinical observations recovered in all other animals.

[1795] Three mice in Group 2 (paclitaxel+vehicle) were found dead or humanely euthanized. No mortality was observed in groups administered AHPPDP.

[1796] Paclitaxel induced allodynia on all Day 5 through 13 test days as defined by ACT score relative to vehicle (FIG. 15). Statistically significant differences were observed between the vehicle+vehicle group (Group 1) compared to paclitaxel+vehicle (Group 2) on all testing days.

[1797] Following intravenous administration of AHPPDP for 2 consecutive days, both low (˜300 mg/kg) and high (˜600 mg/kg) doses of AHPPDP reduced paclitaxel-induced allodynia relative to vehicle on multiple test days as shown in FIG. 16 and FIG. 17, respectively. Both dose levels reduced allodynia on Days 8, 9, and 11; the high dose additionally reduced allodynia on Day 13. There were no statistically significant differences in ACT score between the AHPPDP low and high dose groups. Systemic administration of AHPPDP significantly reduced paclitaxel-induced cool allodynia, which is a functional observation of peripheral neuropathy.

[1798] Cytokine analysis revealed no apparent differences between Groups 2 and 4 for any cytokine except for IL-1β. IL-1β was statistically significantly higher in the AHPPDP-treated group on Day 8, after receiving 2 doses of AHPPDP, and returned to low levels by the end of study (FIG. 19). IL-1β is crucial for both cellular defense and tissue repair, and has a complex role in response to CNS injury.

[1799] These results indicate a composition comprising AHPPDP is useful for treating symptoms of neuropathy.

[1800] The purpose of this study was to evaluate anti-inflammatory effects of AHPPDP on lipopolysaccharide (LPS) induced inflammation as demonstrated by changes in IL 1 beta, IL-6, and TNF alpha cytokine production in THP-1 cells. A composition comprising AHPPDP was prepared as described in Example 23 and sterile filtered, referred to as Composition E26f. 300,000 THP-1 cells were plated per well. Control wells included media only. Cells were contacted with LPS and test articles as outlined in Tables 20 and 21. For a positive control, cells were administered 1.0 μg/mL Candesartan. Candesartan is a statin and known to reduce the production of cytokines. Specifically, candesartan is an angiotensin receptor subtype 1 inhibitor and was utilized as a positive control. The cells were incubated for 1 hour.

[1803] The cells were incubated, and samples of the supernatant were collected at 4 hours and 24 hours. The remaining cells were collected and analyzed for total cell count and percent viability. The Meso Scale Discovery (MSD; Rockville, MS) V-PLEX kit (4-PLEX) with IL-1b, IL-6, IL-8, and TNF-α were used to analyze the cytokines in the media at 4 and 24 hours after LPS stimulation.

[1804] AHPPDP reduced LPS-induced cytokine production in THP-1 cells in a concentration-dependent manner (Table 22, FIG. 18). The positive control, Candesartan, performed as expected, fully reducing the production of cytokines.

[1806] These results indicate AHPPDP has anti-inflammatory properties.

[1807] To evaluate the functional activity of AHPPDP, activation of PDGF receptor α/β (PDGFR α/β) and EGF receptors (EGFR), were assessed. The AHPPDP composition utilized (CUR-001-20L-SEP24) was generated by the method set forth in Example 31, FIG. 26, including concentration of platelet proteins through buffer exchange including removal of citrate and formulating in a suitable buffer.

[1808] The PDGFRα/β assay is a commercially available cell-based reporter assay kit that utilizes proprietary human cells that have been engineered to provide constitutive expression of the human PDGFR α/β. To evaluate PDGF, cells were used which constitutively express both platelet derived growth factor receptors alpha and beta (PDGFRα and PDGFRβ). Agonism of the receptor leads to activation of the Ca⁺² calcineurin nuclear factor of activated T-cells (NFAT) cascade. The NFAT response elements were linked to luciferase. Thus, the presence of functional PDGF would result in increased levels of luciferase. The specificity of signal was confirmed by depleting PDGF in AHPPDP (composition E27f; data not shown).

[1809] The EGFR1 assay is a commercially available cell-based reporter assay kit that utilizes proprietary human cells that provide constitutive expression of the Human Type 1 epidermal growth factor receptor. The reporter cells contain the luciferase reporter gene functionally linked to an upstream minimal promoter and tandem signal transducer and activator of transcription 3 (STAT3) genetic response element sequences. Signaling via EGFR1 activates STAT3, resulting in a dose-dependent luminescent signal.

[1810] AHPPDP contained quantifiable levels of PDGF (FIG. 21A) with a half maximal effective PDGF concentration (EC50) of 0.856 ng/mL. AHPPDP showed functional agonist activity in PDGF receptor activation (FIG. 21B). Matrix effects were present at the higher concentrations of both curves, creating a gel-like reaction in the assay plate. This interference resulted in lower signals at the top end of the curves and limited the ability to see the full agonist activity of AHPPDP.

[1811] AHPPDP contained quantifiable levels of EGF (FIG. 21C) with an EC50 of 0.812 ng/mL. AHPPDP showed functional agonist in EGFR1 receptor activation (FIG. 21D).

[1812] An in vitro cytokine release assay was developed to characterize the anti-inflammatory potential of AHPPDP (see Singh, U., et al., 2005). Briefly, a Tohoku Hospital Pediatrics-1 (THP-1) human monocytic cell line was stimulated with lipopolysaccharide (LPS) to elicit cytokine secretion. AHPPDP (CUR-2401-6L-SEP24) was prepared as described in Example 31, FIG. 26 including concentration of platelet proteins through buffer exchange including removal of citrate and formulating in a suitable buffer. The AHPPDP was added to the cells prior to LPS stimulation to assess if the amount of cytokines are able to be reduced. Candesartan, an angiotensin receptor subtype 1 inhibitor previously shown to reduce cytokine levels, was utilized and confirmed as a positive control. THP-1 cells were pre-incubated with media, vehicle, candesartan at 1 μg/mL or AHPPDP at 10 or 20 mg/mL. The maximum concentration of AHPPDP that could be tested in this assay was 20 mg/mL, due to gelling observed in wells. The cells were then incubated with 500 ng/mL of LPS and cytokine secretion (IL-1, IL-6, IL-8, and TNF-α) was assessed at 4 and 24 hours.

[1813] Results of this assay demonstrate the anti-inflammatory potential of AHPPDP. AHPPDP reduced the levels of cytokine in the media, demonstrating anti-inflammatory activity, as shown in FIG. 22. Levels of IL-6 were reduced over 80% by 10 and 20 mg/mL AHPPDP; IL-13 was reduced 62% by 10 mg/mL AHPPDP, and 74% by 20 mg/mL AHPPDP. Levels of IL-8 were reduced by over 75% by 10 and 20 mg/mL AHPPDP. More modest reductions were observed in TNF-α, with only 25% reduction with 20 mg/mL of AHPPDP. All cytokines were inhibited by 1 μg/mL candesartan. There were either no or negligible cytokine responses when cells were incubated with either concentration of AHPPDP alone (data not shown).

[1814] These studies demonstrate the broad anti-inflammatory activity of AHPPDP in an in vitro assay.

[1815] To investigate the in vivo tolerability of allogeneic human plasma and platelet derived product (AHPPDP, PLS-RPT2007-A-50) formulated in sodium citrate as generated by the foregoing methods, Briefly, platelet suspensions underwent three freeze-thaw cycles, were clarified via centrifugation and filtration, and then buffer exchanged and concentrated. Sprague Dawley rats were utilized. Specifically, adult male rats were administered the test articles set forth in Table 23.

[1817] Sprague Dawley rats (n=1-2/group) were administered AHPPDP, vehicle, or PBS via subcutaneous (SC) or epidural/intrathecal (Epi/IT) injection on Day 1 under light isoflurane anesthesia according to the study design set forth in Table 24 below. The intended route of administration to the rats is epidural, but as the injection was not performed using fluoroscopy (or other) imaging-guided technique the possibility of intrathecal administration cannot be excluded; therefore, the route is called epidural/intrathecal.

[1819] Body weights of the rats were recorded prior to administration of AHPPDP or vehicle, and daily over a 7-day period. Clinical observations were conducted on Day 1 prior to dosing, at 2-6 hours following dosing, and daily thereafter. Blood samples (˜300 μL) were collected via tail/saphenous or jugular veins on Day 2 for complete blood count analysis. Rats were terminated via CO₂ asphyxiation on Day 8.

[1820] A single SC injection of AHPPDP or vehicle-containing sodium citrate was well tolerated, and no abnormal clinical observations were noted over the 7-day period. Conversely, all rats administered either AHPPDP (n=1) or vehicle containing sodium citrate (n=2) via epi/IT injection displayed potentially adverse responses within an hour of administration, indicating the epi/IT injection of sodium citrate-containing formulation was not well tolerated. As a result of this response, these animals were humanely euthanized within an hour and not replaced.

[1821] Modest decreases (less than 10% change from baseline) in body weights were observed beginning on Day 2 in remaining animals that was followed by partial recovery in body weight by Day 8. The results show single subcutaneous injections of AHPPDP and vehicle formulations containing 100 mM sodium citrate were well tolerated in Sprague Dawley rats, whereas a single epi/IT administration of formulations containing 100 mM sodium citrate was not tolerated.

[1822] To investigate the potential immune response of repeat administration of AHPPDP (PLS-RPT2007-A-150) formulated in 100 mM sodium citrate, Sprague Dawley rats were utilized. Briefly, platelet suspensions underwent three freeze-thaw cycles, were clarified via centrifugation and filtration, and then buffer exchanged and concentrated. Adult male and female rats were administered the test articles set forth in Table 25.

[1826] Body weights were recorded prior to dosing and weekly until termination. Detailed clinical observations were conducted prior to dosing and once daily thereafter. Additional observations were conducted approximately 4 hours post dose on dosing days. Blood samples (˜150 μL) was collected via tail/saphenous or jugular veins on Day 16 for comprehensive complete blood count (CBC) analysis. On Day 30, terminal whole blood samples were collected for hematology, serum chemistry, and enzyme-linked immunosorbent assay (ELISA) for quantitation of HSA. Detection and quantitation of HSA was performed using a commercially available human albumin ELISA kit (#ab227933, ABCAM® [Cambridge, UK]) with colorimetric detection. Part of the whole blood was placed in EDTA tubes for CBC and the remainder processed for serum for serum chemistry and ELISA. All rats were terminated on Day 30 via C02 asphyxiation.

[1827] Clinical observations of the rats were performed over the study period. No abnormal clinical observations were noted indicating repeated SC injection of AHPPDP or vehicle containing sodium citrate was well tolerated. Further, there were no apparent differences in intergroup means for hematology parameters vehicle control and AHPPDP group means on Day 15 or Day 30, and no differences in intragroup means for each treatment on Day 15 compared to Day 30. There were no apparent differences in serum chemistry parameters for rats administered vehicle control compared to rats administered AHPPDP on Day 30.

[1828] Human serum albumin (HSA) levels were higher in rats treated with AHPPDP. Specifically, HSA levels on Day 30 were detected in all but one rat administered AHPPDP (Mean±standard error: 5.25E+07±1.64E+07 μg/mL). All rats administered the vehicle control had serum levels below 1.6E+07 μg/mL.

[1829] Following termination, a necropsy was performed on all the rats. No gross pathological changes were observed in animals administered vehicle. Among animals administered AHPPDP, some findings were observed in the heart and/or kidneys, but the relation of these gross observations to the test article is unknown.

[1830] The results indicate that repeated subcutaneous injections of AHPPDP and vehicle formulations containing 100 mM sodium citrate were well tolerated in male and female Sprague Dawley rats. There were no apparent signs of immune response following single or repeated administration of AHPPDP.

[1831] To investigate the impact of depth filter materials on PDGF-AB concentration of AHPPDP, five bags of platelets were thawed at 5° C. for 24 hours and then pooled. The pooled blood was split into two samples. One sample did not have buffer added. A buffer consisting of 100 mM sodium citrate and 5 mM EDTA was added to the second sample. Both samples were centrifuged at 3,000×g for 15 minutes. Polysorbate 80 was spiked into the samples at a final concentration of 0.2%, and the samples were incubated overnight at 5° C. The samples were filtered via depth-filtration using either polyacrylic fiber and silica, diatomaceous earth (DE) and cellulose, or cellulose. The resulting filtrate was labeled “Main”. An additional rinse of the filter was performed to recover any remaining protein and was labeled “Rinse”.

[1832] Following depth filtration, the opacities of the samples was evaluated. Samples that had been filtered with a polyacrylic fiber and silica appeared to be the least opaque. The total protein concentration and PDGF-AB concentration was quantified for the samples. Depth filtration with a cellulose filter resulted in the highest total protein concentration followed by DE and cellulose. A synthetic depth-filter resulted in the lowest protein concentration (FIG. 23). Adding buffer helped retain PDGF-AB during depth-filtration (FIG. 24). Further, rinsing the depth-filter after completion of depth-filtration resulted in recovery of PDGF-AB (FIG. 25).

[1833] Allogenic human plasma and platelet derived product (AHPPDP) was produced and characterized. The process to produce AHPPDP is depicted in FIG. 26 and described below:

• • [1834] Thawing: Platelet suspensions obtained from one or more human donors were thawed at about 4° C. for about 24 to about 60 hours.
  • [1835] Centrifugation: Thawed platelet suspensions were centrifuged at 1,500×g for 5 minutes at 21° C.
  • [1836] Pooling: Thawed platelet suspensions from at least 2 human donors were added to a peristaltic pump and mixed for 10 minutes. The platelet suspensions were then mixed overnight.
  • [1837] Filtration: Pooled platelet suspensions were filtered with a Clarisolve filter and Millistack filter.
  • [1838] Extraction, Viral Inactivation: Platelet proteins were extracted with an extraction buffer comprising 10 mM sodium citrate and 0.2 mM EDTA. Polysorbate 80 was added to a concentration of 0.2%, and the platelet extract was mixed at 21° C. for 3 hours. The platelet extract was then mixed at about 2 to about 8° C. overnight.
  • [1839] Centrifugation: The platelet extract was centrifuged at 4,200×g at 21° C. for 30 minutes.
  • [1840] Filtration: The platelet extract was filtered with a Sartopore Maxicap filter.
  • [1841] Viral Clearance: An S20N filter was used to remove viruses. The platelet extract was filtered three times.
  • [1842] Concentration: The platelet extract was concentrated and buffer exchanged with TFF.
  • [1843] Filtration: The concentrated platelet extract was sterile filtered with a 0.22 μm filter.

[1844] The AHPPDP was produced in 5 lots as described in Table 27 below.

[1846] The AHPPDP was characterized by various properties including but not limited to, protein concentration, bioburden, color and clarity, pH, and osmolality among others. The composition of AHPPDP was evaluated, and the concentrations of various growth factors was quantified via enzyme-linked immunosorbent assay (ELISA) or Meso Scale Discovery (MSD). Specifically, determination of proteins such as VEGF-a, EGF, FGF-2, HGF from AHPPDP was performed with a MSD multiplex panel (U-PLEX platform). Biotinylated capture reagents were coupled to U-PLEX Linkers. In this assay, capture reagents were specific for VEGF-a, EGF, FGF-2, HGF respectively. The U-PLEX Linkers then self-assembled onto unique spots on the U-PLEX plate. After the VEGF-a, EGF, FGF-2 and HGF in the sample were bound to the specific capture reagents, detection antibodies (specific for VEGF-a, EGF, FGF-2, HGF) conjugated with electrochemiluminescent labels (MSD GOLD SULFO-TAG) and were bound to the proteins to complete the sandwich immunoassay. Once the sandwich immunoassay was complete, the plate was placed into an MSD instrument where the amount of proteins present in the sample was measured.

[1847] The PDGF-AB assay employed the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for human PDGF-BB was pre-coated onto a microplate. Standards and samples were pipetted into the wells and any PDGF-AB present was bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for human PDGF-AA was added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution was added to the wells and color developed in proportion to the amount of PDGF-AB bound in the initial step. The color development was stopped, and the intensity of the color was measured.

[1848] Capillary electrophoresis (CE-SDS) was further employed to quantify the proteins present at the highest concentrations. Specifically, the CE-SDS separation technique used 50 m ID bare fused-silica capillary in a cartridge set for a total length of 30.2 cm.

[1849] The characteristics and composition of AHPPDP are outlined in Table 28 below.

[1851] The stability of the AHPPDP compositions were also evaluated. The AHPPDP batches were stored at −80° C. for one month. After one month, the AHPPDP was characterized including but not limited to, protein concentration, composition, pH, and osmolality among others. AHPPDP remained stable following one month of storage (data not shown).

[1852] To further investigate the cytokines present in AHPPDP, a Luminex assay was performed (Eve Diagnostics, Alberta, Canada). The Luminex assay quantified cytokines including, IL-5, IL-1β, IL-6, IL-1RA, IL-10, IL-13, TNFα, IL-8, IL-12p40, and MCP-1. The concentrations of cytokines in each AHPPDP batch are outlined in Table 29 below.

[1854] A scratch assay was developed to evaluate the effects of AHPPDP on wound closure. The test articles are outlined in Table 30 below. Briefly, AHPPDP was prepared based on the methods disclosed herein. AHPPDP (CUR-2401-20L-SEP24) was prepared as described in Example 31, FIG. 26 including concentration of platelet proteins through buffer exchange including removal of citrate and formulating in a suitable buffer.

[1856] 3,000 normal human dermal fibroblasts (NHDF) cells were plated per well. 3.4 ng/mL PDGF-BB in cell media was the positive control. Vehicle at 9% concentration was the negative control. The NHDF cells were starved 48 hours prior to scratch initiation (Day 5) which allowed for higher potential for observing the wound closure effects of PDGF-BB and AHPPDP. Wound closure was measured at 6 and 24 hours after PDGF-BB or AHPPDP treatment.

[1857] The output measures of the scratch assay were, total number of nuclei per well, sum of cell area per well, and sum of empty area per well. Percent wound closure from AHPPDP was relative, and calculated with a PDGF treatment defined as 100%, and a vehicle condition defined as 0%.

[1858] Wound healing compared to vehicle condition was obtained after treatment with 3.7 ng/mL PDGF-BB indicating the positive control performed as expected. Addition of 9% (v/v) of vehicle after scratch initiation resulted in enhanced wound closure at 24 hours after treatment compared to a medium-only condition, in cells that are serum-starved since day 5. Treatment with concentrations of AHPPDP between 2.5 mg/mL and 0.625 mg/mL resulted in higher wound closure relative to vehicle. There were no abnormal observations of nuclei count, indicating there were no potential cytotoxic side effects (data not shown).
