Description:
FIELD OF THE INVENTION 
       [0001]    The field of the invention is directed to methods for treating Hidradenitis Suppurativa. Specifically, the field of the invention is directed to treating and reducing inflammation associated Hidradenitis Suppurativa and promoting healing of wounds associated with Hidradenitis Suppurativa, by administering to a subject suffering from this condition novel cellular factor-containing solution compositions (referred to herein as “CFS” compositions), including novel sustained-release cellular factor-containing solution compositions (referred to herein as “SR-CFS” compositions). 
       BACKGROUND OF THE INVENTION 
       [0002]    Hidradenitis Suppurativa (HS) is a non-contagious inflammatory skin disease that most commonly affects women in body areas that have apocrine sweat glands and/or sebaceous glands, such as the axillary region (underarms), under the breasts, inner thighs, and anogenital region (groin and buttocks). 
         [0003]    HS typically presents as clusters of chronic abscesses, epidermoid cysts, sebaceous cysts, pilonidal cysts and/or multi-localized infections, which can vary in size from a pea to an apple. HS can also start as a single abscess that bursts and forms sinus tracts, or tunnels, under the skin which lead to the formation of more abscesses. These abscesses and cysts can be extremely painful and tender to the touch and may persist for years generally exhibiting occasional to frequent periods of inflammatory flare-ups. These flare-ups can be triggered by several factors including perspiration, hormonal changes (i.e. menstrual hormonal fluctuations), humidity and heat, and friction from clothing. The inflammatory flare-ups often require surgical incision and the drainage of pus from the abscess I order to provide some relief from the severe, sometimes debilitating, pressure and pain experienced by suffers. Unfortunately, HS patients exhibit impaired healing and consequently the incisions tend to develop into open wounds that are difficult to heal. Bacterial infections and cellulitis (deep tissue inflammation) often occur at these non-healing sites. 
         [0004]    Because it is relatively uncommon and patients are embarrassed about the condition, HS often goes undiagnosed for years, is frequently misdiagnosed, or patients are prescribed ineffective treatments. There is currently no known cure or any consistently effective treatment for HS. 
         [0005]    Recommended treatments include a combination of the following: 
         [0006]    Lifestyle changes: These include changes in diet to avoid known inflammatory foods and foods high in refined carbohydrates; applying warm compresses with distilled vinegar water; taking hot baths with distilled white vinegar in the water; icing the inflamed area frequently until pain reduction is noticed; weight loss in overweight patients, and, most importantly, smoking cessation, which is highly positively correlated with HS. 
         [0007]    Medications: These include oral antibiotics, which are used more for their anti-inflammatory properties than to treat infection. One commonly prescribed antibiotic combination is rifampicin and clindamycin. Other non-combination antibiotics used to treat HS include tetracycline, minocycline, and clindamycin. Corticosteroid injections, also known as intralesional steroids, may be useful for localized disease; oral Vitamin A supplements; anti-androgen therapy using cyproterone acetate and ethinyl estradiol; IV or subcutaneous infusion of anti-inflammatory (anti-TNF-alpha) drugs such as infliximab (Remicade®), etanercept (Enbrel®), and adalimumab. It should be noted that this use of these drugs to treat HS is not currently FDA-approved and is somewhat controversial among physicians; oral zinc gluconate; chlorhexidine plus an antibiotic soap for cleansing the skin surface; hexachlorophene shower with a liquid soap such as Phisohex®, coupled with covering sores with Metrolotion® after medicated showers; turmeric capsules orally or via topical application; and topical clindamycin. 
         [0008]    Radiation therapy: Electron beam radiotherapy has been a successful treatment of HS, especially in Europe. However, it is not a common treatment option in most of the United States, as radiation oncologists generally refuse to treat patients with non-malignant diseases because of the potential for secondary radiation-induced tumors in the long term. 
         [0009]    Surgery: This is indicated when the HS diseases state becomes chronic. Wide surgical excision is the procedure of choice. Because wounds in the affected area do not heal well, immediate application of a split thickness skin graft is indicated. 
       BRIEF SUMMARY OF THE INVENTION 
       [0010]    It is believed that a treatment option that could 1) reduce the inflammation and 2) accelerate the healing of the non-healing wounds associated with HS is extremely desirable. Reducing inflammation would lead to a reduction in pain, potentially a reduction in the need for surgical intervention, and reduction in the formation of chronic, non-healing wounds. Accordingly, it is an object of the instant invention to provide such a treatment option for this unmet medical need. 
         [0011]    The instant invention provides novel cellular factor-containing solution (CFS) compositions, including Amnion-derived Cellular Cytokine Solution (ACCS), for use in the described methods for treating HS and for reducing inflammation associated with HS. The instant invention also provides novel sustained-release cellular factor-containing solution (SR-CFS) compositions, including SR-ACCS, for use in the methods. Because the cellular factors in the compositions are present at levels comparable to the physiological levels found in the body, they are optimal for use in therapeutic applications which require intervention to support, initiate, replace, accelerate or otherwise influence biochemical and biological processes involved in the treatment and/or healing of disease and/or injury. In the case of the SR-CFS compositions, the cellular factors are released slowly over time to provide a continual, consistent physiologic level of such factors to optimize healing and/or recovery. Detailed information about the compositions used in the methods can be found in U.S. Pat. Nos. 8,058,066 and 8,088,732, both of which are incorporated herein by reference. 
         [0012]    Applicants have discovered that Amnion-derived Cellular Cytokine Solution (ACCS) (for details see U.S. Pat. Nos. 8,058,066 and 8,088,732, both of which are incorporated herein by reference) exhibits many anti-inflammatory properties as well as wound healing properties. Therefore, ACCS, delivered topically as a liquid, a spray or an ointment, or in other suitable topical delivery vehicles, would be expected to be an effective means of treating HS by reducing inflammation and promoting healing of non-healing wounds associated with HS. 
         [0013]    Accordingly, a first aspect of the invention is a method for treating HS in a patient in need thereof comprising topically administering to the patient a therapeutically effective amount of a CFS composition. 
         [0014]    A second aspect of the invention is a method for reducing inflammation associated with HS in a patient in need thereof comprising topically administering to the patient a therapeutically effective amount of a CFS composition such that inflammation associated with HS is reduced. 
         [0015]    A third aspect of the invention is a method for promoting the healing of non-healing wounds associated with HS in a patient in need thereof comprising topically administering to the patient a therapeutically effective amount of a CFS composition such that the wounds associated with HS heal. 
         [0016]    A particular embodiment of aspects one-three is one in which the CFS composition is Amnion-derived Cellular Cytokine Solution (ACCS). 
         [0017]    Another particular embodiment of aspects one-three is one in which the CFS composition, including ACCS, is formulated for topical administration. In another particular embodiment, the CFS, including ACCS, is formulated for sustained-release. 
         [0018]    A fourth aspect of the invention is a kit comprising a CFS composition and instructions for its use to treat HS. 
         [0019]    A specific embodiment of aspect four is one in which the CFS composition is ACCS, and SR-ACCS. 
         [0020]    In yet another specific embodiment of aspects one-three, the CFS composition, including ACCS, is administered in combination with another agent and/or treatment modality. 
       Definitions 
       [0021]    As defined herein “isolated” refers to material removed from its original environment and is thus altered “by the hand of man” from its natural state. 
         [0022]    As used herein, the term “protein marker” means any protein molecule characteristic of the plasma membrane of a cell or in some cases of a specific cell type. 
         [0023]    As used herein, “enriched” means to selectively concentrate or to increase the amount of one or more materials by elimination of the unwanted materials or selection and separation of desirable materials from a mixture (i.e. separate cells with specific cell markers from a heterogeneous cell population in which not all cells in the population express the marker). 
         [0024]    As used herein, the term “substantially purified” means a population of cells substantially homogeneous for a particular marker or combination of markers. By substantially homogeneous is meant at least 90%, and preferably 95% homogeneous for a particular marker or combination of markers. 
         [0025]    The term “placenta” as used herein means both preterm and term placenta. 
         [0026]    As used herein, the term “totipotent cells” shall have the following meaning In mammals, totipotent cells have the potential to become any cell type in the adult body; any cell type(s) of the extraembryonic membranes (e.g., placenta). Totipotent cells are the fertilized egg and approximately the first 4 cells produced by its cleavage. 
         [0027]    As used herein, the term “pluripotent stem cells” shall have the following meaning Pluripotent stem cells are true stem cells with the potential to make any differentiated cell in the body, but cannot contribute to making the components of the extraembryonic membranes which are derived from the trophoblast. The amnion develops from the epiblast, not the trophoblast. Four types of pluripotent stem cells have been confirmed to date: Embryonic Stem (ES) Cells (may also be totipotent in primates), Embryonic Germ (EG) Cells, Embryonic Carcinoma (EC) Cells, and late Epiblast Stem Cells (EpiSCs). Recently, artificially produced pluripotent stem cells, called induced pluripotent cells (iPCs) have been created in the laboratory. 
         [0028]    As used herein, the term “multipotent stem cells” are true stem cells but can only differentiate into a limited number of types. For example, the bone marrow contains multipotent stem cells that give rise to all the cells of the blood but may not be able to differentiate into other cells types. 
         [0029]    As used herein, the term “extraembryonic tissue” means tissue located outside the embryonic body which is involved with the embryo&#39;s protection, nutrition, waste removal, etc. Extraembryonic tissue is discarded at birth. Extraembryonic tissue includes but is not limited to the amnion, chorion (trophoblast and extraembryonic mesoderm including umbilical cord and vessels), yolk sac, allantois and amniotic fluid (including all components contained therein). Extraembryonic tissue and cells derived therefrom have the same genotype as the developing embryo. 
         [0030]    As used herein, the term “extraembryonic cytokine secreting cells” or “ECS cells” means a population of cells derived from the extraembryonic tissue which have the characteristics of secreting a unique combination of physiologically relevant cytokines in a physiologically relevant temporal manner into the extracellular space or into surrounding culture media and which have not been cultured in the presence of any animal-derived products, making them and cell products derived from them suitable for human clinical use. In a preferred embodiment, the ECS cells secrete the cytokines VEGF, Angiogenin, PDGF and TGFβ2 and the MMP inhibitors TIMP-1 and/or TIMP-2. The physiological range of the cytokine or cytokines in the unique combination is as follows: ˜5-16 ng/mL for VEGF, ˜3.5-4.5 ng/mL for Angiogenin, ˜100-165 pg/mL for PDGF, ˜2.5-2.7 ng/mL for TGFβ2, ˜0.68 μg/mL for TIMP-1 and ˜1.04 μg/mL for TIMP-2. The ECS cells may optionally express Thymosin 134. 
         [0031]    As used herein, the term “amnion-derived multipotent progenitor cell” or “AMP cell” means a specific population of ECS cells that are epithelial cells derived from the amnion. In addition to the characteristics described above for ECS cells, AMP cells have the following characteristics. They have not been cultured in the presence of any animal-derived products, making them and cell products derived from them suitable for human clinical use. They grow without feeder layers, do not express the protein telomerase and are non-tumorigenic. AMP cells do not express the hematopoietic stem cell marker CD34 protein. The absence of CD34 positive cells in this population indicates the isolates are not contaminated with hematopoietic stem cells such as umbilical cord blood or embryonic fibroblasts. Virtually 100% of the cells react with antibodies to low molecular weight cytokeratins, confirming their epithelial nature. Freshly isolated amnion-epithelial cells will not react with antibodies to the stem/progenitor cell markers c-kit (CD117) and Thy-1 (CD90). Several procedures used to obtain cells from full term or pre-term placenta are known in the art (see, for example, US 2004/0110287; Anker et al., 2005, Stem Cells 22:1338-1345; Ramkumar et al., 1995, Am. J. Ob. Gyn. 172:493-500). However, the methods used herein provide improved, novel compositions and populations of cells. 
         [0032]    By the term “animal-free” when referring to certain compositions, growth conditions, culture media, etc. described herein, is meant that no non-human animal-derived materials, such as non-human animal-derived serum, other than clinical grade human materials, such as recombinantly produced human proteins, are used in the preparation, growth, culturing, expansion, storage or formulation of the certain composition or process. 
         [0033]    By the term “serum-free” when referring to certain compositions, growth conditions, culture media, etc. described herein, is meant that no non-human animal-derived serum is used in the preparation, growth, culturing, expansion, storage or formulation of the certain composition or process. 
         [0034]    By the term “expanded”, in reference to cell compositions, means that the cell population constitutes a significantly higher concentration of cells than is obtained using previous methods. For example, the level of cells per gram of amniotic tissue in expanded compositions of AMP cells is at least 50 and up to 150 fold higher than the number of cells in the primary culture after 5 passages, as compared to about a 20 fold increase in such cells using previous methods. In another example, the level of cells per gram of amniotic tissue in expanded compositions of AMP cells is at least 30 and up to 100 fold higher than the number of cells in the primary culture after  3  passages. Accordingly, an “expanded” population has at least a  2  fold, and up to a  10  fold, improvement in cell numbers per gram of amniotic tissue over previous methods. The term “expanded” is meant to cover only those situations in which a person has intervened to elevate the number of the cells. 
         [0035]    As used herein, “conditioned medium” is a medium in which a specific cell or population of cells has been cultured, and then removed. When cells are cultured in a medium, they may secrete cellular factors that can provide support to or affect the behavior of other cells. Such factors include, but are not limited to hormones, cytokines, extracellular matrix (ECM), proteins, vesicles, antibodies, chemokines, receptors, inhibitors and granules. The medium containing the cellular factors is the conditioned medium. Examples of methods of preparing conditioned media are described in U.S. Pat. No. 6,372,494 which is incorporated by reference in its entirety herein. As used herein, conditioned medium also refers to components, such as proteins, that are recovered and/or purified from conditioned medium or from ECS cells, including AMP cells. 
         [0036]    As used herein, the term “cellular factor-containing solution” or “CFS” composition means a composition having physiologic concentrations of one or more protein factors.

         [0038]    As used herein, the term “Physiologic Cytokine Solution” or “PCS” composition means a composition which is not cell-derived and which has physiologic concentrations of VEGF, Angiogenin, PDGF and TGFβ2, TIMP-1 and TIMP-2. 
         [0039]    As used herein, the term “suspension” means a liquid containing dispersed components, i.e. cytokines The dispersed components may be fully solubilized, partially solubilized, suspended or otherwise dispersed in the liquid. Suitable liquids include, but are not limited to, water, osmotic solutions such as salt and/or sugar solutions, cell culture media, and other aqueous or non-aqueous solutions. 
         [0040]    The term “lysate” as used herein refers to the composition obtained when cells, for example, AMP cells, are lysed and optionally the cellular debris (e.g., cellular membranes) is removed. This may be achieved by mechanical means, by freezing and thawing, by sonication, by use of detergents, such as EDTA, or by enzymatic digestion using, for example, hyaluronidase, dispase, proteases, and nucleases. In certain instances, it may be desirable to retain the cell membranes, as well. 
         [0041]    The term “physiologic” or “physiological level” as used herein means the level that a substance in a living system is found and that is relevant to the proper functioning of a biochemical and/or biological process. 
         [0042]    As used herein, the term “substrate” means a defined coating on a surface that cells attach to, grown on, and/or migrate on.

As used herein, the term “scaffold” means a three-dimensional (3D) structure (substrate and/or matrix) that cells grow in or on. It may be composed of biological components, synthetic components or a combination of both. Further, it may be naturally constructed by cells or artificially constructed. In addition, the scaffold may contain components that have biological activity under appropriate conditions. 
         [0043]    The term “cell product” or “cell products” as used herein refers to any and all substances made by and secreted from a cell, including but not limited to, protein factors (i.e. growth factors, differentiation factors, engraftment factors, cytokines, morphogens, proteases (i.e. to promote endogenous cell delamination, protease inhibitors), extracellular matrix components (i.e. fibronectin, etc.), and the like. 
         [0044]    The term “therapeutically effective amount” means that amount of a therapeutic agent necessary to achieve a desired physiological effect (i.e. to treat HS). 
         [0045]    As used herein, the term “pharmaceutically acceptable” means that the components, in addition to the therapeutic agent, comprising the formulation, are suitable for administration to the patient being treated in accordance with the present invention. 
         [0046]    As used herein, the term “therapeutic component” means a component of the composition which exerts a therapeutic benefit when the composition is administered to a subject. 
         [0047]    As used herein, the term “therapeutic protein” includes a wide range of biologically active proteins including, but not limited to, growth factors, enzymes, hormones, cytokines, inhibitors of cytokines, blood clotting factors, peptide growth and differentiation factors.

         [0052]    As used herein, the term “agent” means an active agent or an inactive agent. By the term “active agent” is meant an agent that is capable of having a physiological effect when administered to a subject. Non-limiting examples of active agents include growth factors, cytokines, antibiotics, cells, conditioned media from cells, etc. By the term “inactive agent” is meant an agent that does not have a physiological effect when administered. Such agents may alternatively be called “pharmaceutically acceptable excipients”. Non-limiting examples include time release capsules and the like.

         [0062]    Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, the preferred methods and materials are now described. 
         [0063]    It must be noted that as used herein and in the appended claims, the singular forms “a,” “and” and “the” include plural references unless the context clearly dictates otherwise. 
         [0064]    Compositions and Methods of Making Compositions 
         [0065]    Detailed information and methods on the preparation of AMP cell compositions, generation of ACCS, generation of pooled ACCS, detection of cytokines in non-pooled and pooled ACCS using ELISA and/or antibody array, generation of PCS compositions, and generation of sustained-release CFS compositions can be found in U.S. Pat. Nos. 8,058,066 and 8,088,732, both of which are incorporated herein by reference in their entirety. 
         [0066]    The invention provides for an article of manufacture comprising packaging material and a pharmaceutical composition of the invention contained within the packaging material, wherein the pharmaceutical composition comprises CFS compositions, including ACCS. The packaging material comprises a label or package insert which indicates that the CFS compositions, including ACCS, contained therein can be used for therapeutic applications such as, for example, treating HS. 
         [0067]    Formulation, Dosage and Administration of CFS Compositions 
         [0068]    Compositions comprising CFS compositions, including ACCS, may be administered to a subject to provide various cellular or tissue functions, for example, to treat HS. As used herein “subject” may mean either a human or non-human animal. 
         [0069]    Such compositions may be formulated in any conventional manner using one or more physiologically acceptable carriers optionally comprising excipients and auxiliaries. Proper formulation is dependent upon the route of administration chosen. For topical administration, the CFS compositions may be formulated as a spray, liquid, cream, foam, gel, lotion, salve, and ointment, etc. The compositions may also be administered to the recipient in one or more physiologically acceptable carriers. Carriers for CFS compositions may include but are not limited to solutions of normal saline, phosphate buffered saline (PBS), lactated Ringer&#39;s solution containing a mixture of salts in physiologic concentrations, or cell culture medium. 
         [0070]    In addition, one of skill in the art may readily determine the appropriate dose of the CFS compositions for a particular purpose. A preferred dose is in the range of about 0.1-to-1000 micrograms per square centimeter of applied area. Other preferred dose ranges are 1.0-to-50.0 micrograms/applied area. In a particularly preferred embodiment, it has been found that relatively small amounts of the CFS compositions are therapeutically useful. One exemplification of such therapeutic utility is the ability for ACCS (including pooled ACCS) to accelerate wound healing (for details see U.S. Publication No. 2006/0222634 and U.S. Pat. No. 8,187,881, both of which are incorporated herein by reference). One of skill in the art will also recognize that the number of doses to be administered needs also to be empirically determined based on, for example, severity and type of disease, disorder or injury being treated; patient age, weight, sex, health; other medications and treatments being administered to the patient; and the like. For example, in a specific embodiment, one dose may be sufficient to have a therapeutic effect (i.e. treat HS). Other specific embodiments contemplate, 2, 3, 4, or more doses for therapeutic effect. 
         [0071]    One of skill in the art will also recognize that number of doses (dosing regimen) to be administered needs also to be empirically determined based on, for example, severity and type of injury, disorder or condition being treated; patient age, weight, sex, health; other medications and treatments being administered to the patient; and the like. In addition, one of skill in the art recognizes that the frequency of dosing needs to be empirically determined based on similar criteria. In certain embodiments, one dose is administered every day for a given number of days (i.e. once a day for 7 days, etc.). In other embodiments, multiple doses may be administered in one day (every 4 hours, etc.). Multiple doses per day for multiple days are also contemplated by the invention. 
         [0072]    In further embodiments of the present invention, at least one additional agent may be combined with the CFS compositions. Such agents may act synergistically with the CFS compositions of the invention to enhance the therapeutic effect. Such agents include but are not limited to cleansing agents, vitamins, anti-hormone agents, growth factors, cytokines, chemokines, antibodies, inhibitors, antibiotics, immunosuppressive agents, steroids, anti-fungals, anti-virals or various cell types (i.e. stem cells or stem-like cells, for example, AMP cells). Inactive agents include carriers, diluents, stabilizers, gelling agents, delivery vehicles, ECMs (natural and synthetic), scaffolds, and the like. When the CFS compositions are administered conjointly with other pharmaceutically active agents, even less of the CFS compositions may be needed to be therapeutically effective. 
         [0073]    CFS compositions may also be inserted into a delivery device, e.g., a tube, in different forms. For example, the CFS compositions can be part of a solution contained in such a delivery device. As used herein, the term “solution” includes a pharmaceutically acceptable carrier or diluent. Pharmaceutically acceptable carriers and diluents include saline, aqueous buffer solutions, solvents and/or dispersion media. The use of such carriers and diluents is well known in the art. The solution is preferably sterile and fluid to the extent that easy syringability exists. Preferably, the solution is stable under the conditions of manufacture and storage and may optionally be preserved against the contaminating action of microorganisms such as bacteria and fungi through the use of, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. Solutions of the invention can be prepared by incorporating the CFS compositions in a pharmaceutically acceptable carrier or diluent and, as required, other ingredients enumerated above. 
         [0074]    The timing of administration of CFS compositions will depend upon the type and severity of the disease, disorder, or injury being treated. In one embodiment, the CFS compositions are administered as soon as possible after onset of symptoms or diagnosis. In another embodiment, CFS compositions are administered more than one time following onset of symptoms or diagnosis. 
         [0075]    Support matrices, scaffolds, membranes and the like into which the CFS compositions can be incorporated or embedded include matrices which are recipient-compatible and which degrade into products which are not harmful to the recipient. Detailed information on suitable support matrices, etc., can be found in U.S. Pat. Nos. 8,058,066 and 8,088,732, both of which are incorporated herein by reference. 
         [0076]    A “therapeutically effective amount” of a therapeutic agent within the meaning of the present invention will be determined by a patient&#39;s attending physician or veterinarian. Such amounts are readily ascertained by one of ordinary skill in the art and will enable treating HS when administered in accordance with the present invention. Factors which influence what a therapeutically effective amount will be include, the specific activity of the therapeutic agent being used, the extent of the lesion, abscess or wound, the absence or presence of infection, time elapsed since a surgical procedure, the advancement of the disease and the age, physical condition, existence of other disease states, and nutritional status of the patient. Additionally, other medication the patient may be receiving will effect the determination of the therapeutically effective amount of the therapeutic agent to administer. 
       EXAMPLES 
       [0077]    The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how to make and use the compositions and methods of the invention, and are not intended to limit the scope of what the inventors regard as their invention. Efforts have been made to ensure accuracy with respect to numbers used (e.g., amounts, temperature, etc.) but some experimental errors and deviations should be accounted for. Unless indicated otherwise, parts are parts by weight, molecular weight is average molecular weight, temperature is in degrees centigrade, and pressure is at or near atmospheric. 
         [0078]    The following examples provide in vivo experimental evidence of the anti-inflammatory and wound healing effects of ACCS is several different inflammatory conditions (mucosal, mucosal/infected; skin (intact and lesioned); and cutaneous wound/infected), thus providing strong evidence for the broad applicability of ACCS to prevent and/or treat inflammatory conditions and non-healing wound such as that associated with HS. 
       Example 1 
     Inflammatory Model—Use of ACCS to Prevent Onset of Periodontal Disease in an Animal Model 
       [0079]    Objective: The aim of this study was to evaluate the preventive role of ACCS in  Porphyromonas gingivalis  ( P. gingivalis )-induced experimental periodontitis in rabbits 
         [0080]    Methods: Eight New-Zealand White rabbits were distributed into 3 groups: 1. Untreated (n=2), 2. Control (unconditioned ACCS culture media) (n=3), and 3. ACCS (n=3). At baseline, all rabbits received silk ligatures bilaterally tied around mandibular second premolars under general anesthesia. The assigned test materials, ACCS or control, in volumes of 10 μL were topically applied to the ligated sites with a blunt needled-Hamilton Syringe from the time of ligature; control animals received ligature, but no treatment. Topical  P. gingivalis -containing slurry (1 mL) was subsequently applied to induce the periodontal inflammation. The application of test materials and  P. gingivalis  continued for 6 weeks on an every-other-day schedule. At 6 weeks, following euthanasia, the mandibles were surgically harvested. Morphometric, radiographic and histologic evaluations were performed. 
         [0081]    Results: Macroscopic evaluations including soft tissue assessments, crestal bone and infrabony measurements showed significant periodontal breakdown induced by  P. gingivalis  in control and no treatment groups at 6 weeks compared to historical ligature-alone groups (p=0.05, p=0.03, respectively). ACCS application significantly inhibited soft tissue inflammation and prevented both crestal bone loss and infrabony defect formation compared to untreated and control groups (p=0.01, p=0.05, respectively). Histologic assessments and histomorphometric measurements supported the clinical findings; ACCS treated animals demonstrated significantly less inflammation in soft tissue and less bone loss compared to the untreated and control groups (p=0.05). 
         [0082]    Conclusions: Topical ACCS application prevents periodontal inflammatory changes and bone loss induced by  P. gingivalis  as shown both at clinical and histopathological level. ACCS has potential as a therapeutic approach for the prevention of periodontal diseases 
       Example 2 
     Inflammatory Model—Use of ACCS to Stop Progression of or Reverse Periodontal Disease in an Animal Model 
       [0083]    Objective: The aim of this study was to evaluate the therapeutic actions of ACCS in the treatment of periodontitis induced by  P. gingivalis.    
         [0084]    Methods: The study was conducted using a two-phase rabbit periodontitis protocol: 1-Disease induction (6 weeks) and 2-Treatment (6 weeks). Periodontal disease was induced in 16 New-Zealand White rabbits by every-other-day application of topical  P. gingivalis  to ligatured mandibular premolars. At the end of Phase 1, 4 randomly selected rabbits were sacrificed to serve as the baseline disease group. For Phase 2, the remaining 12 rabbits were distributed into 3 groups (n=4), 1-Untreated, 2-Control (unconditioned ACCS culture media) and 3-ACCS treatment. At the end of Phase 2, morphometric, radiographic and histologic evaluations were performed on harvested mandibles. 
         [0085]    Results: The baseline disease group exhibited experimental periodontitis evidenced by tissue inflammation and bone loss. At the end of Phase 2, the untreated group showed significant disease progression characterized by increased soft and hard tissue destruction (p=0.05). The tissue inflammation and bone loss was significantly reduced by topical ACCS compared to baseline disease and untreated groups (p=0.05; p=0.002, respectively). The control treatment also arrested disease progression compared to untreated group (p=0.01), but there was no improvement in periodontal health compared to baseline disease (p=0.4). Histopathological assessments revealed similar findings; ACCS stopped the progression of inflammatory process (p=0.003) and reversed bone destruction induced by  P. gingivalis  (p=0.008). The ACCS-treated group had minimal osteoclastic activity limited to crestal area compared to untreated and control groups, which showed a profound osteoclastogenic activity at the bone crest as well as at interproximal sites. 
         [0086]    Conclusions: Topical application of ACCS stopped the progression of periodontal inflammation and resulted in tissue regeneration in rabbit periodontitis indicating its potential therapeutic efficacy. 
       Example 3 
     Inflammatory Model—Evaluate the Efficacy of Topically Applied ACCS to Inhibit Irritant 12-O-tetradecanoylphorbol-13-acetate (TPA) Skin Inflammation in Mice 
       [0087]    Method: Topical treatment was given twice daily to the following groups: 1. TPA+topical control; 2. TPA+ACCS; 3. TPA+clobetasol 0.05 topical solution (the strongest available topical corticosteroid); 4. ACCS alone; 5. No treatment (the other untreated ear was measured). The endpoints for the study were ear thickness and ear weight at the end of the experiment. The thicker the ear and the more it weighs correlates with the degree of inflammation. 
         [0088]    Results: Topically applied ACCS was effective at reducing the inflammation induced by TPA. The anti-inflammatory activity of topical ACCS reached the same level as clobetasol (a class 1 potent topical corticosteroid) by 3 days after beginning application. 
         [0089]    Conclusion: ACCS has a strong anti-inflammatory effect when applied to skin. 
       Example 4  
     Inflammatory Model—Evaluate the efficacy of intralesional injection of ACCS to inhibit irritant (TPA) skin inflammation in mice. 
       [0090]    Method: Intralesional injection into the ear was given once daily to the following groups: 1. TPA+intralesional control; 2. TPA+intralesional ACCS; 3. TPA+intralesional kenalog (10 mg/ml) (a potent intralesional corticosteroid); 4. ACCS intralesional injection alone; 5. Saline sham injections to the normal untreated ear. The endpoints for the study were ear thickness and ear weight at the end of the experiment. The thicker the ear and the more it weighs correlates with the degree of inflammation. 
         [0091]    Results: Intralesional injection of ACCS was effective at reducing the inflammation induced by TPA at all time points beginning on day 2 of daily injections. Intralesional kenalog (10 mg/ml) injections induced a hematoma at the site of injection, which led to some inflammation and that is why there is not a substantial difference in ear thickness when comparing TPA+kenalog with TPA+control. 
         [0092]    Conclusions: Intralesional ACCS did reduce skin inflammation but the topically applied ACCS in Example 1 above had a more potent effect. There was no difference in ear weight using either ACCS or intralesional kenalog compared with TPA+control. 
       Example 5 
     Wound Healing Model—Effects of ACCS in an Animal Model of Chronic Wound Healing 
       [0093]    An art-accepted animal model for chronic granulating wound was used to study the effects of ACCS on chronic wound healing (Hayward PG, Robson MC: Animal models of wound contraction. In Barbul A, et al: Clinical and Experimental Approaches to Dermal and Epidermal Repair: Normal and Chronic Wounds. John Wiley &amp; Sons, New York, 1990.). 
         [0094]    Results: ACCS was effective in not allowing proliferation of tissue bacterial bioburden. ACCS allowed accelerated healing of the granulating wound significantly faster than the non-treated infected control groups (Franz, M., et al., ePlasty Vol. 8, pp. 188-199, Apr. 11, 2008).
