The present application provides bio-mimetic formulations, including formulations that mimic mammalian amniotic membrane and/or fluid, but with optimized amounts and formulas of various recombinant peptides. These formulations are stable for extended periods and can be used in various treatment methods including wound healing.
The mammalian amniotic membrane is derived from the inner layer of the placenta and is composed of conjoined amnion and chorion membranes. (See, e.g., Koob et al., “Properties of Dehydrated Human and Amnion/Chorion Composite Grafts: Implications for Wound Repair and Soft Tissue Regeneration,” Journal of Biomedical Materials Research B: Applied Biomaterials 00B:000-000 (2014)). The amniotic membrane holds the developing fetus and amniotic fluid, so this thin membrane must possess the structural integrity to support the pregnancy through term. It is a metabolically active tissue which continually remodels the extracellular matrix (ECM) through processes governed by paracrine growth factors. Required nutrients are supplied to the amniotic membranes directly by diffusion out of the amniotic fluid or from the underlying decidua. In addition to physically encasing the amniotic fluid and developing fetus, amniotic membranes play an integral biological role in fetal development and progression of pregnancy; therefore, amniotic membrane grafts harbor significant biological activity, including a number of developmental cytokines.

Storage and preservation is crucial for the success of many applications involving biological materials. To date, a variety of devices and methods have been used to prepare biological materials in a dehydrated form in order to confer benefits such as reduced weight and reduced storage space, and also increased chemical and/or structural stability. While each of these devices have certain benefits, they also come with certain detriments including one or more of the following, prolonged drying time, limited capacity, uneven drying, use of chemicals which can modify the biological materials and compromise their functions. Other methods use sugars to stabilize biological materials prior to freeze-drying. These types of processes, however, can produce ice crystals and damage biological material structures.
What is needed is a bio-mimetic formulation that provides the medical benefits of amniotic fluid and the amniotic membrane, in a more accessible, easier to control embodiment.
The present invention fulfills these needs by obviated the logistic and cost associated with human tissue recovery and processing. Additionally, the formulations described herein can be normalized to contain precise, repeatable concentrations of any of the components.

In embodiments, provided herein are various bio-mimetic formulations that include a carrier and various combinations of any of the following recombinant peptides:
As used herein, the term “bio-mimetic formulation” refers to a composition that includes components designed to mimic or imitate a biological structure or solution, including for example, the amniotic fluid and/or the amniotic membrane.
The bio-mimetic formulations described herein include a carrier. As used herein, “carrier” means a non-active element(s), ingredient(s) or excipient(s) of the formulations, and can include a liquid, a foam, an emulsion (oil-in-water or water-in-oil), a solid, a gel, a lotion, a semi-solid, and other suitable forms. In embodiments, the carrier of the formulations is a liquid carrier. That is, the carrier has the form of a flowable substance, and suitably includes components such as an aqueous primary component (e.g., water), along with other components dissolved within the primary component, including various pharmaceutically acceptable excipients. Examples of components that can be dissolved within the primary component, include for example, various salts, buffers, diluents, electrolytes, bulking agents, etc. Exemplary excipients which can be used in the carriers include, but are not limited to, a diluent, vehicle, preservative, binder or stabilizing agent. Examples of excipients include, but are not limited to, proteins (e.g., serum albumin), amino acids (e.g., aspartic acid, glutamic acid, lysine, arginine, glycine and histidine), surfactants (e.g., SDS, polysorbate and nonionic surfactant), saccharides (e.g., glucose, sucrose, maltose and trehalas), polyols (e.g., mannitol and sorbitol), fatty acids and phospholipids (e.g., alkyl sulfonates and caprylate). For additional information regarding excipients, see Remington's Pharmaceutical Sciences (by Joseph P. Remington, 18th ed., Mack Publishing Co., Easton, Pa.), which is incorporated herein in its entirety.
In embodiments, the liquid carrier includes serum, which refers to the fluid remaining after blood as coagulated. In additional embodiments, a plasma-like solution can be used as the liquid carrier. For example, a solution such as PLASMA-LYTE A Injection pH 7.4 (Multiple Electrolytes Injection, Type 1, USP) which is a sterile, nonpyrogenic isotonic solution in a single dose container for intravenous administration can be utilized. In embodiments, 100 mL contains 526 mg of Sodium Chloride, USP (NaCl); 502 mg of Sodium Gluconate (C6H11NaO7); 368 mg of Sodium Acetate Trihydrate, USP (C2H3NaO2.3H2O); 37 mg of Potassium Chloride, USP (KCl); and 30 mg of Magnesium Chloride, USP (MgCl2.6H2O). Suitably, it contains no antimicrobial agents. The pH is adjusted with sodium hydroxide to about 7.4 (6.5 to 8.0). One liter has an ionic concentration of 140 mEq sodium, 5 mEq potassium, 3 mEq magnesium, 98 mEq chloride, 27 mEq acetate, and 23 mEq gluconate. The osmolarity is 294 mOsmol/L (calc). Normal physiologic osmolarity range is 280 to 310 mOsmol/L. The caloric content is 21 lcal/L.
Solid carriers can also be used in the bio-mimetic formulations described herein, and can take the forms of various pills, capsules, suppositories, creams, lotions, depot forms and any successor forms, etc. In addition, a solid carrier can also include a bio-mimetic formulation which was prepared in a liquid form, and then the liquid removed via dehydration, lyophilization, evaporation, or the formulation freeze dried, or otherwise prepared, as a solid form.
The terms “recombinant polypeptide,” “recombinant peptide,” “recombinant protein,” and “recombinant protein fragment” are used interchangeably herein to refer to a polymer of amino acid residues that is synthesized synthetically (i.e., not simply isolated from a biological sample), suitably produced by expression of a recombinant (synthetic) nucleic acid. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymers.
Methods of preparing recombinant peptides are well known in the art, and include various vector and protein expression systems, including viral vectors, plasmids, liposome based-transfection, etc., and the use of bacterial (e.g., E. Coli) or other host cells for replication and protein production. Exemplary methods can be found for example in Protein Expression Technologies: Current Status and Future Trends, Baneyx ed., Horizon Bioscience, Norfolk, UK (2004), the disclosure of which is incorporated by reference herein in its entirety, including the methods disclosed therein. Methods of preparing recombinant peptides also include various filtration and purification steps, such as column filtration, dialysis, etc.

In further embodiments, the bio-mimetic formulations include all of the recombinant peptides, or between 1-51 of the recombinant peptides, and in other embodiments at least 1, at least 2, at least 3, at least 4, at least 5, at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40, at least 45, at least 50, or in some embodiments, the bio-mimetic formulations include each of the 51 recombinant peptides listed in Table 1.
In additional embodiments, the bio-mimetic formulations include all of the recombinant peptides, or between 1-51 of the recombinant peptides, and in other embodiments at least 1, at least 2, at least 3, at least 4, at least 5, at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40, at least 45, at least 50, or in some embodiments, the bio-mimetic formulations include each of the 51 recombinant peptides of the recombinant peptides listed below, at the amounts set forth in the various Tables herein.

The volume of the formulation includes the volume of the carrier(s) used to prepare the formulation. In further embodiments, the amounts of the recombinant peptides can be measured in weight/weight, with the weight of the formulation including the weight of the carrier(s) used to prepare the formulation.
As described herein, it has been surprisingly found that the amounts (pg/mL) of the recombinant peptides included in the bio-mimetic formulations, which are approximately three or more times above those found naturally in the amniotic membrane or amniotic fluid, can be prepared together and provided to a mammalian patient for the treatment of various conditions, ailments, diseases, etc.

Exemplary proteins and other active agents include, but are not limited to, Manuka honey, cannabidiol (CBD—a non-narcotic fraction of Cannabis sativa), psilocybin (i.e., prodrug derived from mushrooms), etc.
In additional embodiments, the bio-mimetic formulations can consist essentially of 1-51, or in other embodiments 5-51, or 10-51 of the recombinant peptides listed in Table 1, or 10-51 of the recombinant peptides at the amounts specified in the various Tables disclosed herein. In bio-mimetic formulations that consist essentially of a number of recombinant peptides (e.g., 1051, 5-51, 10-51, 20-51, 30-51, 40-51, 10-50, 10-45, 10-40, 10-35, 10-30, 10-25, 10-20, 10-15, 20-40, 20-30, 30-40, or 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, or 51, etc., of the recombinant peptides, including values and ranges within these ranges), the bio-mimetic formulations do not include any additional recombinant peptides from those recited in Table 1, or any additional active peptides or proteins, or other active agents, but the bio-mimetic formulations can include additional non-active ingredients or excipients (including those listed herein), that do not affect the basic and novel characteristics of the formulations.
In still further embodiments, the bio-mimetic formulations can include any of, and in embodiments, at least 10 of or at least 20 of the recombinant peptides described herein at the following amounts:
In still further embodiments, the bio-mimetic formulations can include any of, or in embodiments at least 10 or or at least 20 of the recombinant peptides described herein at the following amounts:
In addition to those picogram/milligram amounts and ranges of the recombinant peptides described herein, the bio-mimetic formulations can also include various different amounts, ranges and ratios of the recited recombinant peptides, including specific amounts within those ranges described herein. In embodiments, the amounts of the recombinant peptides can be optimized for use in various patient populations, for treatment of various conditions or diseases, etc. Modification of the amounts of the recombinant peptides can be achieved by reducing or increasing the amounts of the recombinant peptides (including increasing the amount of certain recombinant peptides while reducing the amount of other recombinant peptides), by various amounts. For example, one or more of the recombinant peptides in the bio-mimetic formulations can be increased or reduced relative to one or more other recombinant peptides in the bio-mimetic formulations by about 1-500%, about 1-200%, about 1-100%, about 1-90%, about 1-80%, about 1-70%, about 1-60%, about 1-50%, about 1-40%, about 1-30%, about 1-20%, about 1-10%, about 1-5%, about 10%-20%, about 20%-30%, about 30%-40%, about 40%-50%, about 50%-60%, about 60%-70%, about 70%-80%, about 80%-90%, about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 90%, etc. In addition, the amounts of various recombinant peptides can be increased by the amounts noted, while the amounts of other recombinant peptides are reduced.
In further embodiments, the amounts of the various recombinant peptides can be increased or reduced by 0.1-times, 2-times, 5-times, 10-times, 100-times, or even 1000-times above and below those ranges provided herein. For example Table 5 below shows ranges 10-times higher and 10-times lower than those listed above:
Ratios of the amounts of the various recombinant proteins can be modified from those disclosed herein to provide formulations that have improved or specific biological effects in a target patient or population. For example, the ratio of one or more of the recited growth factors to one or more of the recited interleukins can be modified (increased or decreased) to provide an improve or enhanced effect.
In additional embodiments, the bio-mimetic formulation consists of a carrier and each of the recombinant peptides recited in Table 1, or each of the recombinant peptides recited in Table 2 at the amounts recited, or each of the recombinant peptides recited in Table 3 at the amounts recited, or each of the recombinant peptides recited in Table 4 at the amounts recited. As described herein, preparation of bio-mimetic formulations consisting of each of the recombinant peptides at amounts that are least 2-fold, for example at least 3-fold higher (including about 10-times higher) than those found in nature, provide unexpected benefits to patients. In addition, it has been unexpectedly determined that utilizing the recombinant proteins described herein at the elevated amounts (2 or 3-fold or more above that found in a biological sample), still allows for the recombinant proteins to work and interact as needed with their biological targets to exert the required or desired effects. Increasing the amount of one or more recombinant proteins above that found in nature, while still allowing for the proteins to function as required, without causing deleterious side effects, was an unexpected finding. Similarly, modifying the ratios of the recombinant proteins in a manner that is different from that found in nature, while still maintaining a desired biological outcome, was also unexpected.
In still further embodiments, provided herein are bio-mimetic formulations consisting of a carrier and 1-51, 1-50, 5-50, 10-50, or 10-40, or 20-45, or 20-40, or 20-30, or 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45 or 50 of the recombinant peptides recited in Table 1.
Still additional embodiments provide a bio-mimetic formulation comprising a carrier and the following recombinant peptides. Table 6 separates the recombinant proteins in to similar “classes” or “types” of recombinant proteins.
In embodiments of the bio-mimetic formulations set forth in Table 5, the formulations can include at least 2, 3, 4, 5, etc. of the recited classes of recombinant proteins. Various combinations of the recited classes can also be prepared, for example 1, 2, 3, 4 or 5, of one class of recombinant protein, in combination with 1, 2, 3, 4 or 5, etc., of another class, or other classes, of recombinant proteins.
In further embodiments, the bio-mimetic formulations which include various combinations of classes of recombinant proteins can include combinations from Table 7 and/or Table 8, set forth below:
In additional embodiments, provided herein are methods of preparing the various bio-mimetic formulations disclosed throughout. In embodiments, the methods include obtaining the various combinations and mounts of the recombinant proteins, mixing the recombinant proteins in a suitable carrier, and storing the bio-mimetic formulation in a container.
In embodiments that utilize a liquid carrier, the carrier components are suitably prepared and mixed, and then the recombinant peptides are added according to the desired amounts and various combinations. The use of suitable buffer systems and stabilizers can allow the bio-mimetic formulations to be stored in a glass, plastic, metal, etc., container for periods of at least about 30 days at about 4-8° C. In other embodiments, the bio-mimetic formulations can be stored for at least about 60 days, at least about 90 days, at least about 120 days, at least about 240 days, at least about 1 year, or about 1-3 years, about 1-5 years, etc., at 4-8° C.

As described herein, methods of producing recombinant proteins are known in the art, and in embodiments, the methods of preparation described herein include preparing the various peptides using vector systems, including viral plasmids, bacterial production systems, etc. to generate the recombinant proteins, followed by purification/filtration if necessary, prior to mixing with the various carrier systems.
In further embodiments, methods of preparing a dried, bio-mimetic formulation are provided. In such embodiments, various amounts and combinations of the recombinant proteins described herein are obtained and mixed with a liquid carrier. This liquid carrier can then be dried (i.e., the aqueous component removed), for example by using dehydration, lyophilization, desiccation, etc., resulting in a dried carrier formulation.
In other embodiments, a dried, bio-mimetic formulation can be prepared by obtaining various amounts and combinations of the recited recombinant proteins, and mixing into a liquid carrier. A solid scaffold matrix or extracellular matrix can also be prepared. The recombinant peptides in the carrier are then applied to the solid scaffold matrix. The liquid (e.g., water) in the carrier can then be removed, leaving a dried composition of the recombinant proteins on the solid scaffold matrix. Methods of drying the recombinant protein compositions onto the solid scaffold matrix include evaporation, dehydration, desiccation, lyophilization, freeze drying, etc.

In vitro experiments are carried out to determine the effect of the bio-mimetic formulation on human fibroblast and human keratinocyte migration (independently) in a Wound Healing Scratch Assay. For this assay, human keratinocyte cells are seeded to form a confluent monolayer on Day 0. After verifying existence of a monolayer, on Day 1 a scratch is made to ‘wound’ the cellular monolayer. Microscopy is used to follow the migration of the cells as the monolayer is re-established. The microscopy data is analyzed to determine cellular migratory speed as well as other important parameters.
The results are expected to demonstrate improved cellular vitality and migration in combination with the bio-mimemitic formulation, as compared to controls.

The bio-memtic formulation is applied to a wound on the skin surface of the mammalian patient twice per day, for a period of at least 4 weeks.
Following the treatment, the wound on the skin surface of the mammal is found to heal more rapidly than a control wound (i.e., untreated, or treated only with a liquid carrier composition).
The bio-mimetic formulation of Example 1 is prepared for administration via injection into a mammalian patient.
The bio-memtic formulation is injected into an area of the mammal where connective tissue rejuvenation is desired.
Following the treatment, the connective tissue is found to rejuvinate more rapidly than a control tissue (i.e., untreated, or treated only with a liquid carrier composition).
