1 / 69 Combined therapy of clascoterone and minoxidil for use in the treatment of hair loss. FUNDAMENTALS
[0001] Alopecia is a group of disorders with multiple and variable etiologies that result in hair loss from the body. The most common form of alopecia is androgenetic alopecia (“AGA”). AGA is also commonly called male pattern baldness or male or female pattern hair loss. AGA has been reported to affect approximately 50% of men over 40 years of age. This form of alopecia could eventually affect up to 80% of white men by around 70 years of age and about half of all women. Hair loss is often a cause of great concern to affected individuals for cosmetic and psychological reasons, but it can also be an important sign of systemic disease.
[0002] The medical management of AGA includes surgical treatment options, including hair transplantation. This procedure has been successfully performed for decades. Hair transplantation involves harvesting intact hair follicles from within a safe donor area (SDA) of a patient's scalp by follicular unit strip harvesting surgery (FUSS) or follicular unit extraction (FUE). Although cosmetic results after surgery are often satisfactory, surgery can only be performed when a sufficient number of donor plugs (or follicles) are available to cover the balding area(s). Additionally, hair transplantation is generally reserved for patients who have experienced massive hair loss and for patients in whom AGA is not yet progressing.In younger patients, for example, hair transplantation is generally not recommended, as androgens, particularly dihydrotestosterone (DHT), can act on the newly transplanted follicles, resulting in the same thinning and eventual hair loss that affected the follicles originally. Petition 870250088666, dated 09 / 30 / 2025, page 18 / 102 2 / 69 present.
[0003] In view of the shortcomings and disadvantages associated with surgical treatment options, there remains a need in the field for pharmacological therapies for the treatment of hair loss, including alopecia and, in particular, AGA. BRIEF SUMMARY
[0004] Minoxidil, also known as 2,4-diamino-6-piperidinopyrimidine 3-oxide, is formulated as a topical pharmaceutical product for the treatment of AGA, typically in two potency levels: 2% (topical solution) and 5% (as a topical solution or foam). See, for example, U.S. Patents Nos. 4,596,812 and 6,946,120, each of which is incorporated into this descriptive report by reference in its entirety. To exert its effect, minoxidil needs to be transformed into its active metabolite, minoxidil sulfate, by the enzyme sulfotransferase. This enzyme is present in the outer root sheath of anagen follicles. Unfortunately, clinical trials have shown that topical application of a 2% minoxidil solution to patients with hair loss results in stimulated dense hair regrowth in less than about 5% of patients and moderate hair regrowth in only about 30% of patients. See, for example, E.A. Olsen et al., "Topical Minoxidil in Early Male Pattern Baldness, J. Amer. Acad. Derm. 13, 185-192 (1985); and J. Roberts, "Androgenetic Alopecia: Treatment with Topical Minoxidil, J. Amer. Academic. Derm. 16 (3) 705-710 (1987).
[0005] Cortexolone-17α-propionate, also known as 17α-propionyloxy-21-hydroxy-pregna-4-ene-3,20-dione and clascoterone, is a topical antiandrogen that displaces androgenic hormones from binding to their receptors. Cortexolone-17α-propionate is known to be suitable for the treatment of acne, alopecia, and other diseases of the skin and cutaneous appendages. See, for example, US Patents Nos. 8,143,240 and 8,865,690. Petition 870250088666, dated 09 / 30 / 2025, page 19 / 102 3 / 69 WO 2009 / 019138 and WO 2016 / 207778. The compound is also known to exist in several distinct crystalline polymorphs, each having unique properties. See, for example, US Patent No. 8,785,427. Each of these patents is incorporated into this descriptive report by reference in its entirety.
[0006] It has been surprisingly discovered that hair loss, including alopecia, can be effectively treated with a combination of cortexolone-17α-propionate and minoxidil. In some embodiments, a synergistic effect can be provided by the combination so that, surprisingly, a smaller effective amount of each active ingredient can be used for effective treatment or the same amount of each active ingredient can be used to obtain greater combined synergy. As a result of this combined therapy, an advantageous clinical outcome can be observed after daily topical administration for an appropriate amount of time, such as a few days, weeks, or months.

[0098] In some embodiments, the acid may be added in a sufficient quantity so that the pH of the pharmaceutical formulation may be about 7.0 or less (e.g., about 4 to about 7.0, about 4 to about 6.5, about 4 to about 6, about 4 to about 5.5, about 4 to about 5, about 4.5 to about 7.0, about 4.5 to about Petition 870250088666, dated 09 / 30 / 2025, page 49 / 102 33 / 69 6.5, approximately 4.5 to approximately 6, approximately 4.5 to approximately 5.5, approximately 4.5 to approximately 5, approximately 5 to approximately 7.0, approximately 5 to approximately 6.5, approximately 5 to approximately 6, approximately 5 to approximately 5.5, approximately 5.5 to approximately 7.0, approximately 5.5 to approximately 6.5, approximately 5.5 to approximately 6, approximately 6 to approximately 7.0, or approximately 6 to approximately 6.5).
[0099] In some embodiments, the pharmaceutical formulation may include a buffer to help maintain the pH of the formulation within a desired range. In some embodiments, the buffer may be a phosphate buffer, citrate buffer, lactate buffer, or a combination thereof. In some embodiments, the formulation may comprise phosphoric acid, citric acid, lactic acid, or a combination thereof.
[0100] Because oxidation can result in degradation of the active agent, in some embodiments, the pharmaceutical formulation may include an antioxidant. In some embodiments, the antioxidant may be, for example, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), ascorbyl palmitate, ascorbic acid, alpha tocopherol, propyl gallate, 2,4,5-trihydroxybutyrophenone, 4-hydroxymethyl-2,6-di-tert-butylphenol, erythorbic acid, guaiac gum, thiodipropionic acid, dilauryl thiodipropionate, tert-butylhydroquinone, pharmaceutically acceptable salts or esters thereof, and combinations thereof. In some embodiments, the antioxidant may be ascorbyl palmitate, BHA, BHT, or a combination thereof. In some formulations, the antioxidant may be BHT, ascorbyl palmitate, or a combination of BHT and ascorbyl palmitate.
[0101] In some embodiments, the pharmaceutical formulation may include up to about 1% of the weight of an antioxidant. In some embodiments, the pharmaceutical formulation may include up to about 0.5% of the weight of an antioxidant or include about 0.5% of the weight of the antioxidant.
[0102] In some forms, the pharmaceutical formulation may Petition 870250088666, dated 09 / 30 / 2025, p. 50 / 102 34 / 69 include an emulsifier, particularly to provide a solution, a suspension, an emulsion, or a microemulsion. Without wanting to be tied to any particular theory, it is believed that emulsifiers, when present, help or facilitate the dissolution of any solid substances, such as an active agent, in the pharmaceutical formulation. In other embodiments, however, the emulsifier may be present to facilitate the incorporation of two immiscible liquids into each other (for example, to form an emulsion or microemulsion).
[0103] In other embodiments, and without wishing to be bound to any particular theory, an emulsifier may increase the spreadability of the product. For example, and without wishing to be bound to any particular theory, when the pharmaceutical formulation is a liquid solution, it is believed that the presence of an adequate amount of an emulsifier increases the surface tension between the pharmaceutical formulation and the lipid environment of the superficial layer of the skin and / or scalp. This makes it easier to spread the pharmaceutical formulation and is believed to aid in the penetration of the active agent(s) into the skin (including the scalp), hair follicles, or both.
[0104] In some embodiments, the emulsifier may be selected from the group comprising or consisting of: polyethylene glycol (PEG) fatty acid monoesters such as, for example, PEG-15 hydroxystearate (also known as polyoxyl-15-hydroxystearate), PEG-30 stearate, PEG-40 laurate, PEG-40 oleate and the like; polyoxyethylene sorbitan fatty acid esters (polysorbates) such as, for example, polysorbate 20, polysorbate 60, polysorbate 80 and the like; polyoxyethylene alkyl ethers such as, for example, PEG-20 cetostearyl ether, polyoxyl 25 cetostearyl, cetomacrogol 1000 and the like; sorbitan fatty acid esters such as, for example, sorbitan monolaurate, Petition 870250088666, dated 09 / 30 / 2025, page 51 / 102 35 / 69 sorbitan monopalmitate, sorbitan monooleate and the like; propylene glycol fatty acid esters; polyglycerol fatty acid esters; polyoxyethylene castor oil derivatives such as, for example, polyoxyl 5 castor oil, polyoxyl 15 castor oil, polyoxyl 35 castor oil, hydrogenated polyoxyl 40 castor oil and the like; caprylocapril polyoxyl-8 glycerides; polyoxylglycerides such as, for example, caprylocaproyl polyoxylglycerides, lauroyl polyoxylglycerides, oleoyl polyoxylglycerides and the like; polyoxyethylene lauryl alcohol; together with combinations of any of the aforementioned. In some embodiments, the emulsifier may be hydrogenated castor oil polyoxyl 40, polyoxyl-15-hydroxystearate, polysorbate 60, polysorbate 80, or a combination thereof.In preferred embodiments, the emulsifier may be a polysorbate such as, for example, polysorbate 60, polysorbate 80, or a combination of polysorbate 60 and polysorbate 80.
[0105] In some embodiments, the pharmaceutical formulation may include the emulsifier in an amount of up to about 5% of the total formulation weight (e.g., up to about 4% of the weight, up to about 3% of the weight, up to about 2% of the weight). In some embodiments, the emulsifier may be present in an amount ranging from 0.05 to 5% of the weight (e.g., from about 0.05% of the weight to about 4% of the weight, from about 0.05% of the weight to about 3% of the weight, from about 0.05% of the weight to about 2% of the weight). In preferred embodiments, the pharmaceutical formulation may include the emulsifier in an amount of approximately 0.1% by weight, approximately 0.2% by weight, approximately 0.3% by weight, approximately 0.4% by weight, approximately 0.5% by weight, approximately 0.6% by weight, approximately 0.7% by weight, approximately 0.8% by weight, approximately 0.9% by weight, approximately 1% by weight, approximately 1.5% by weight, approximately 2% by weight, approximately 2.5% by weight, approximately 3% by weight, approximately 3.5% by weight, approximately 4% by weight, approximately 4.5% by weight. Petition 870250088666, dated 09 / 30 / 2025, page 52 / 102 36 / 69 by weight or about 5% by weight. In further embodiments, the pharmaceutical formulation may include the emulsifier in an amount up to about 0.1% by weight, or it may include about 0.1% by weight of emulsifier. In further embodiments, the emulsifier may be present in the pharmaceutical formulation at about 0.1% by weight.
[0106] In some embodiments, the pharmaceutical formulation may include one or more penetration enhancers. Without adhering to a specific theory, penetration enhancers are believed to beneficially affect the release of the active agent(s) into the skin (including the scalp) and / or hair follicles. Advantageously, and in some embodiments, the solvent or some component (or components) of the solvent acts as a penetration enhancer. For example, in embodiments where the pharmaceutical formulation comprises ethanol and / or diethylene glycol monoethyl ether, these solvents may also act to increase the penetration of the active agent into the skin (including the scalp), hair follicles, or both. Notwithstanding the presence of ethanol and / or diethylene glycol monoethyl ether, the pharmaceutical formulations described in this descriptive report may still include additional penetration enhancers.
[0107] In some embodiments, the penetration enhancer may be selected from the group consisting of hydroxypropyl β-cyclodextrin, a diol, a polyol, a fatty acid (e.g., myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, or a combination thereof), a fatty alcohol, a fatty acid ester, a surfactant, a pyrrolidone, and combinations thereof. Examples of additional penetration enhancers that may be incorporated into formulations described in this descriptive report include, without limitation, polyoxymethylene alkyl ethers, polyoxyl glycerides, dimethyl sulfoxide, pyrrolidone, N Petition 870250088666, dated 09 / 30 / 2025, page 53 / 102 37 / 69 methyl-2-pyrrolidone, diethylene glycol monoethyl ether (e.g., TRANSCUTOL™, Gattefossé, France), dimethyl isosorbide, diethyl sebacate, azone, menthol, nerol, camphor, methyl salicylate, polysorbate 80 (e.g., TWEEN™ 80, Sigma-Aldrich, St. Louis, MO), SDS, benzalkonium chloride, polyoxyl 40 hydrogenated castor oil (e.g., CREMOPHOR™ RH40, KOLLIPHOR™ RH40, BASF, Germany), didecyldimethylammonium bromide (DDAB), didecyltrimethylammonium bromide (DTAB), fatty acid esters (e.g., isopropyl myristate, isopropyl palmitate), fatty acids (e.g., oleic acid, acid palmitic acid, linoleic acid, and salts thereof), fatty alcohols (e.g., oleyl alcohol, myristyl alcohol, and stearyl alcohol), medium-chain triglycerides, and combinations of any of the foregoing.
[0108] In some embodiments, the penetration enhancer may be dimethyl isosorbide. In other embodiments, the penetration enhancer may be a mixture comprising dimethyl isosorbide and diethylene glycol monoethyl ether. In other embodiments, the penetration enhancer may be dimethyl sulfoxide.
[0109] In some embodiments, the penetration enhancer may be present in an amount ranging from about 1% to about 50% of the weight relative to the total weight of the pharmaceutical formulation. In other embodiments, the penetration enhancer may be present from about 2% to about 40% of the weight relative to the total weight of the pharmaceutical formulation; or from about 5% to about 35% of the weight relative to the total weight of the pharmaceutical formulation. According to some embodiments, the penetration enhancer may be present in the pharmaceutical formulation described in this descriptive report in an amount of about 1%, about 2%, about 5%, or about 35% of the weight relative to the total weight of the pharmaceutical formulation. Petition 870250088666, dated 09 / 30 / 2025, p. 54 / 102 38 / 69 of 10% of the weight, approximately 15% of the weight, approximately 20% of the weight, approximately 25% of the weight, approximately 30% of the weight, approximately 35% of the weight, approximately 40% of the weight, approximately 45% of the weight, or approximately 50% of the weight in relation to the total weight of the pharmaceutical formulation.
[0110] In some embodiments, the pharmaceutical formulation may include one or more moisturizers. Without adhering to a specific theory, a moisturizer is believed to impart moisture and / or softness to the skin (including the scalp), particularly when a component known to dry the skin, such as an alcohol, is also present in the formulation. In some embodiments, the moisturizer may be a fatty alcohol, a fatty acid (e.g., myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, or a combination thereof), a fatty acid ester, an oil, a polyethylene glycol, glycerin, an alpha hydroxy acid, or a combination thereof.In some embodiments, the moisturizer may be cetyl alcohol, cetearyl alcohol, stearyl alcohol, stearic acid, isopropyl myristate, isopropyl palmitate, cocoa butter, lanolin, liquid paraffin, shea butter, a silicone oil, castor oil, a polyethylene glycol, glycerin, lactic acid, glycolic acid, malic acid, citric acid, tartaric acid, or a combination thereof. In some embodiments, the moisturizer may be cetyl alcohol, stearyl alcohol, or a combination of cetyl alcohol and stearyl alcohol.

[0112] In some embodiments, the pharmaceutical formulation may include one or more chelating agents. Suitable chelating agents include, for example, citric acid, phytic acid, sodium phytate, clioquinol, ethylenediaminetetraacetic acid (EDTA) (e.g., disodium EDTA, tetrasodium EDTA), etidronic acid, galactaric acid, tetrahydroxypropyl ethylenediamine, sodium metasilicate, or a combination thereof. Methods of administration
[0113] The pharmaceutical formulations described in this descriptive report may be co-administered according to varying dosage regimens. In one embodiment, the method of administration of the pharmaceutical formulation may be continuous. For example, the pharmaceutical formulations may be applied topically once daily, twice daily, three times daily, four times daily, or more, as specified by a physician. In some embodiments, a formulation described in this descriptive report may be applied topically once daily or twice daily. According to a particular embodiment, the pharmaceutical formulation described in this descriptive report may be applied topically once daily. According to another embodiment, the pharmaceutical formulation described in this descriptive report may be applied topically twice daily.
[0114] In some embodiments, a dosage regimen can be changed gradually. That is, the pharmaceutical formulation can be applied once a day for an initial period of time, twice a day thereafter for a second period of time, three times a day thereafter for a third period of time, and so on. In one particular embodiment, the Petition 870250088666, dated 09 / 30 / 2025, p. 56 / 102 The 40 / 69 pharmaceutical formulation may be administered once daily on the first day, and twice daily thereafter, with the appropriate treatment duration determined by the individual's physician. Alternatively, gradual changeover of administration may involve administering the pharmaceutical formulation on a tapering schedule, starting with multiple administrations per day for an appropriate period of time and reducing the number of administrations over an appropriate period of time until a maintenance dosage schedule can be achieved. It is within the knowledge of a physician skilled in the art, armed with the present disclosure, to determine the appropriate starting point, rate of tapering, and maintenance dosage schedule.
[0115] In some embodiments, the pharmaceutical formulation may be applied over the duration of a period of days, weeks or months. For example, the pharmaceutical formulation may be applied once, twice, three, four or five times a day for up to: 1, 2, 3, 4, 5, 6 or 7 days (i.e., about 1 week); about 2 weeks, about 3 weeks or about 4 weeks; approximately 2 months, approximately 3 months, approximately 4 months, approximately 5 months, approximately 6 months, approximately 7 months, approximately 8 months, approximately 9 months, approximately 10 months, approximately 11 months, approximately one year (i.e., approximately 12 months), approximately 13 months, approximately 14 months, approximately 15 months, approximately 16 months, approximately 17 months, approximately 18 months, approximately 19 months, approximately 20 months, approximately 21 months, approximately 22 months, approximately 23 months, or approximately 24 months.

In some embodiments, the pharmaceutical formulation may be applied topically to the scalp more than twice a day (i.e., TID, QID, etc.) for 12 months.
[0119] In another modality, the mode of administration of Petition 870250088666, dated 09 / 30 / 2025, p. 58 / 102 42 / 69 pharmaceutical formulations can be cyclical. For example, the pharmaceutical formulation may first be applied continuously as described above for a desired period of time, the application may then be suspended for a period of time such as, for example, a few days, and then the application of the pharmaceutical formulations may be started again, as described above. The treatment period may include one or more cycles which may be the same or different. In some modalities, the treatment period may be as follows: a) the pharmaceutical formulation may be applied topically to the scalp for a period of time such as, for example, 4 months, by continuous administration, b) the application may be suspended for a few days (e.g., 2 to 5 days), and 3) the topical application may be continued for an additional period of time such as, for example, 6 months.
[0120] In some embodiments, the method of administration may be cyclical, in that cortexolone-17α-propionate and minoxidil may be co-administered sequentially. For example, a pharmaceutical formulation comprising cortexolone-17α-propionate may be administered first for a first period of time, and a pharmaceutical composition comprising minoxidil may be administered second for a second period of time. In other embodiments, a pharmaceutical composition comprising minoxidil may be administered first and a pharmaceutical composition comprising cortexolone-17α-propionate may be administered second. The time period between when the first pharmaceutical composition may be administered and the second pharmaceutical composition may be administered may be any suitable time period. For example, the time between each administration may be on the order of seconds, minutes, hours, or days, as required.In some embodiments, the administration of the first and second pharmaceutical compositions may be separated by seconds (for example, approximately 60 seconds or less, approximately. Petition 870250088666, dated 09 / 30 / 2025, p. 59 / 102 43 / 69 seconds or less). In some embodiments, the administration of the first and second pharmaceutical compositions may be separated by hours (e.g., approximately 1 hour or less, approximately 2 hours or less, approximately 3 hours or less, approximately 5 hours or less, approximately 8 hours or less, approximately 12 hours or less, approximately 24 hours or less). In some embodiments, the administration of the first and second pharmaceutical compositions may be separated by days (e.g., approximately 1 day, approximately 2 days, approximately 3 days, approximately 4 days, approximately 5 days, approximately 6 days, or approximately 7 days). In some embodiments, the administration of the first and second pharmaceutical compositions may be separated by weeks (e.g., approximately 1 week, approximately 2 weeks, approximately 3 weeks, or approximately 4 weeks).
[0121] In some embodiments, a first pharmaceutical formulation comprising cortexolone-17α-propionate or minoxidil may be administered for an initial period of time, which may be on the order of days or weeks. During the initial period of time, the first pharmaceutical formulation may be administered multiple times to the skin or scalp, as described in this descriptive report, before a second pharmaceutical formulation comprising the other active agent may be administered for a second period of time. Similar to the initial period of time, the second period of time may be on the order of days or weeks. For example, a first pharmaceutical formulation comprising cortexolone-17α-propionate may be administered for an initial period of time (e.g., about 1 day or more, about 2 days or more, about 7 days or more, about 2 weeks or more, about 3 weeks or more, or about 4 weeks or more).A second pharmaceutical formulation comprising minoxidil may be administered for a second period of time (e.g., about 1 day or more, about 2 days or more, about 7 days or more, about 2 weeks or more). Petition 870250088666, dated 09 / 30 / 2025, pp. 60 / 102 44 / 69 plus, approximately 3 weeks or more or approximately 4 weeks or more). In some modalities, an individual may alternate (e.g., cycle between) administration between the first and second pharmaceutical formulations for a certain period of time to effect treatment.

[0139] Storage stability is an important metric for pharmaceutical products. In general, greater stability means that a given formulation is both easier to transport and store, which increases the likelihood that it will be stocked by pharmacies and that individuals will not have to worry about special storage instructions. In some embodiments, the pharmaceutical formulation described in this descriptive report may have a desirable stability profile allowing the final formulation to be stored for at least about 3 months, at least about 6 months, at least about 9 months, at least about 12 months, at least about 15 months, at least about 18 months, at least about 21 months, or at least about two years – each at room temperature (around 20°C) or at refrigerated temperatures (e.g., around 4°C).
[0140] For example, one of the main degradation pathways of cortexolone-17α-propionate is transesterification to cortexolone-21-propionate (17α-hydroxy-21-propionyloxy-pregna-4-ene-3,20-dione): .0 \θH� Petition 870250088666, dated 09 / 30 / 2025, pp. 71 / 102 55 / 69
[0141] In some embodiments, maintaining the pharmaceutical formulations disclosed in this descriptive report at an acidic pH, including a pH of less than 7.0 (for example, less than about 6.5, less than about 6, less than about 5.5, less than about 5, less than about 4.5, between about 4 and about 7, between about 4 and about 6.5, between about 4 and about 6, between about 4 and 5.5, between about 4 and 5, between about 4 and about 4.5, or at about 6.5, about 6, about 5.5, about 5, about 4.5 or about 4), may slow down this degradation process. In some applications, the pH may be around 4. The appropriate pH can be obtained by adding an adequate amount of a pH modifier, such as the acids described in this descriptive report.
[0142] In some embodiments, the pharmaceutical formulations described in this descriptive report may, at room temperature (around 20°C) or at refrigerated temperatures (e.g., around 4°C), have less than about 5% by weight of cortexolone-21-propionate or other degradation products after storage for a period of about 24 months.

The combined treatment of clascoterone and minoxidil synergistically inhibits IL-6 secretion in Human Hair Follicle Dermal Papilla (HFDPC) cells.
[0157] Clascoterone is a potent antiandrogen that blocks the effects of the androgen receptor in human hair follicles. Topical administration demonstrates clinically significant efficacy in AGA. Part of its mechanism of action is to inhibit androgen-induced IL-6 secretion by HFDPC, and this reduces IL-6-induced hair follicle damage. Thus, IL-6 secretion by these cells is a relevant efficacy biomarker that correlates with hair growth.
[0158] Minoxidil is a KATP channel modulator that demonstrates topical efficacy in AGA. There are no reports of its effects on IL-6 secretion in HFDPC.
[0159] In this study, the combination of clascoterone with minoxidil in inhibiting IL-6 secretion by HFDPC was better than expected. That is, the combined efficacy was greater than the simple addition of the efficacy of each agent alone.
[0160] The results suggest that the synergistic combination of Petition 870250088666, dated 09 / 30 / 2025, pp. 77 / 102 61 / 69 topical clascoterone and topical minoxidil should provide significantly increased efficacy when used in patients with AGA. Rationale
[0161] The majority of the hair follicle is composed of keratinocytes, the epithelial cells that comprise the hair shaft itself, as well as the inner and outer root sheaths that surround it. However, a specialized mesenchymal population, the dermal papilla (DP), plays a critical role in directing the activities of these keratinocytes to form the follicle and generate the hair shaft (Greco et al. 2009). Active communication between the DP or its precursors and the epithelial compartment regulates many aspects of follicle biology. The DP influences the size and shape of the hair shaft by generating signals that act on the keratinocytes.
[0162] In androgenetic alopecia, a reduction in hair follicle size associated with progressive thinning and hair loss includes an inability to maintain PD cell function (Elliott et al. 1999). Several observations suggest that this stems from a primary defect in PD. One of the fundamental paracrine factors produced by PD cells in male pattern baldness is the cytokine IL-6.
[0163] IL-6, in response to dihydrotestosterone (DHT), is upregulated in PD cells in baldness compared to PD cells without baldness (Kwack et al. 2012); IL-6 receptors are expressed in follicular keratinocytes, including matrix cells. Recombinant human IL-6 (rhIL-6) inhibited hair shaft elongation and suppressed matrix cell proliferation in cultured human hair follicles. Furthermore, rhIL-6 injection into the hypodermis of mice during anagen (hair growth phase) caused premature onset of catagen (growth inhibition). Thus, DHT-inducible IL-6 inhibits hair growth as a paracrine mediator by PD (Kwack et al. 2012). Petition 870250088666, dated 09 / 30 / 2025, pp. 78 / 102 62 / 69
[0164] There are three classes of drugs that are effective in halting the progression of hair loss: antiandrogens (e.g., Clascoterone), 5-α-reductase type 2 inhibitors (e.g., Finasteride), and KTP channel inhibitors (e.g., Minoxidil). These compounds act on PD cells in cell cultures or isolated hair follicles (Kaufman et al. 1998; Randall 2008; Shorter et al. 2008).
[0165] Clascoterone has been shown to inhibit DHT-induced IL-6 expression in dermal papilla cells (Rosette et al. 2019). However, it is not known whether minoxidil can modulate IL-6 expression in PD cells or whether the combination of clascoterone and minoxidil may demonstrate greater efficacy than either agent alone. Experimental section Cell lines
[0166] Human Hair Follicle Dermal Papilla (HFDPC) cells from the vertex region of the human scalp were obtained from Cell Applications (San Diego, CA). Cells were propagated in Complete Hair Follicle Dermal Papilla Cell Basal Medium (Cell Applications, San Diego, CA) and 10% fetal bovine serum (Gibco, Gaithersburg, MD). All flasks and plates used were coated with collagen. Collagen was obtained from Cell Applications (San Diego, CA) and used according to the manufacturer's instructions. For analysis of IL6 secretion, cells were trypsinized and seeded (2 x 10⁵ cells per well) in 24-well collagen-coated plates containing Dermal Hair Follicle Papilla Cell Basal Medium and 5% charcoal-dextran filtered serum (DCC-FBS) (Omega Scientific, Tarzana, CA) and incubated overnight. Experiments were performed in triplicate in wells.The following day, the medium was removed and fresh Basal medium + DCC-FBS 5% containing the compounds and DHT were added and incubated for 24 hours. All cell incubations were performed at 37°C and 5% CO2. For the... Petition 870250088666, dated 09 / 30 / 2025, pp. 79 / 102 63 / 69 concentrations of compounds used in these experiments were determined to have no significant effect on cell proliferation (data not shown). Compounds
[0167] Clascoterone (CB0301) was custom synthesized for Cosmo Pharmaceuticals (Lainate, Italy). Dihydrotestosterone (DHT) was obtained from Millipore-Sigma (Saint Louis, MO) and Minoxidil was obtained from VWR (San Diego, CA). All compounds were dissolved in 100% DMSO and then diluted in 5% HFDP + DCC-FBS Basal Medium for cell culture experiments. The final DMSO concentrations in each well were 0.1%. Quantification of IL-6 protein expression by ELISA.
[0168] Various concentrations of DHT, clascoterone, and minoxidil were used to treat dermal papilla cells. The compounds were added simultaneously (without pre-incubation) to the wells. After 24 hours of culture, the medium in each well was collected and used immediately for the determination of secreted IL-6. The Human IL-6 ELISA detection kit was from Invitrogen (San Diego, CA) and used according to the manufacturer's instructions. Absorbance was quantified using a ClarioStar microplate reader (Ortenberg, Germany), and the data were analyzed using Prism software version 10.1.1 (GraphPad, La Jolla, CA). Results
[0169] Figure 1 shows that incubation of HFDPC with 100 nM DHT for 24 hours resulted in significantly increased IL-6 secretion, compared with 0.1% DMSO used as a control (47.5 pg / ml vs. 39.2 pg / ml; p < 0.004). Minoxidil at a concentration of 1 mM in the presence of DHT only slightly decreased IL-6 secretion by 7% (47.5 pg / ml to 44.3 pg / ml).
[0170] Clascoterone in the presence of 100 nM DHT inhibited Petition 870250088666, dated 09 / 30 / 2025, pages 80 / 102 64 / 69 dose-dependently affects IL-6 secretion over 24 hours. Importantly, the combination of 1 μM Minoxidil with 15 nM or 30 nM doses of clascoterone showed an unexpected synergism resulting in significantly greater inhibition of IL-6 secretion compared to treatment with clascoterone alone. The 60 nM clascoterone group also showed synergism, but without statistical significance.
[0171] All clascoterone treatment groups showed statistically significant inhibition of IL-6 secretion, relative to 100 nM DHT. Table 8 lists the IL-6 concentrations and their relation to inhibition by the compounds in each treatment condition. Table 8. Mean and standard deviation of IL-6 concentrations in relation to inhibition by the compounds in each experimental treatment group. Condition IL-6 Mean (pg / ml) Standard deviation (pg / ml) % relative inhibition for 100 nM DHT DMSO 39.0 5.8 100 nM DHT 47.5 6.1 Only 1 μM MNX 42.2 5.6 1 μM MNX + DHT 44.3 4.1 7% 15 nM CB0301 + 100 nM DHT 39.7 2.8 16% 30 nM CB0301 + 100 nM DHT 38.4 6.4 19% 60 nM CB0301 + 100 nM DHT 31.3 3.0 34% Petition 870250088666, dated 09 / 30 / 2025, pages 81 / 102 65 / 69 15 nM CB0301 / 1 μM MNX / DHT 31.4 ± 2.6 34%
[0172] As shown in Figure 2, when comparing the effects of clascoterone + DHT vs. clascoterone + DHT + minoxidil, the clascoterone treatment groups containing 1 μM of minoxidil showed more than an additive effect. That is, there was a synergistic inhibition of IL-6 in HFDPC for all concentrations of clascoterone when combined with 1 μM of minoxidil.
[0173] The predictive additive efficacy for the clascoterone and minoxidil combination vs. the actual observed efficacy of the combination is listed in Table 9. This also includes the p-values from the ANOVA statistical analysis comparing the means of the clascoterone + DHT groups vs. the clascoterone + DHT + minoxidil groups. Table 9. Predicted additive effect of (clascoterone + DHT) + (minoxidil + DHT) vs. observed effect of the combination and statistical analysis of the p-value of the mean clascoterone vs. mean of the clascoterone + minoxidil treatment groups. Clascoterone concentration (nM) Predicted additive effect (%) Observed effect of the combination (%) P-value 15 23% 34% P < 0.009 30 26% 36% P < 0.003 Petition 870250088666, dated 09 / 30 / 2025, pages 82 / 102 66 / 69 60 41% 43% P < 0.7
[0174] The 15 nM clascoterone + DHT group showed 16% inhibition compared to DHT alone, and the 1 mM minoxidil + DHT group showed 7% inhibition compared to DHT alone. Therefore, an additive effect should provide 23% (16% + 7%) inhibition. However, the 34% inhibition observed for the clascoterone + DHT + minoxidil combination is greater than 23%, indicating a synergistic inhibition between clascoterone and minoxidil when used in combination. The combined treatment was significantly different compared to clascoterone + DHT (p < 0.009).
[0175] The 30 nM clascoterone group showed 19% inhibition compared to DHT alone, and the 1 mM minoxidil group showed 7% inhibition compared to DHT alone. Therefore, an additive effect should provide 26% (19% + 9%) inhibition. However, the 36% inhibition observed for the combination is higher, indicating synergistic inhibition between clascoterone and minoxidil when used in combination. The combined treatment (clascoterone + DHT + minoxidil) was significantly different compared to clascoterone + DHT (p < 0.003).
[0176] The 60 nM clascoterone group showed 34% inhibition compared to DHT alone, and the 1 mM minoxidil group showed 7% inhibition compared to DHT alone. Therefore, an additive effect should provide 41% (34% + 7%) inhibition. The 43% inhibition observed for the combination is higher, which may indicate synergistic inhibition. However, this difference was not significant (p < 0.7). Conclusion
[0177] Human dermal papilla cells respond to DHT to activate the androgen receptor. IL-6 is a crucial negative regulator of hair growth and has been shown to be elevated. Petition 870250088666, dated 09 / 30 / 2025, pp. 83 / 102 67 / 69 in hair follicles of the scalp with baldness compared to hair follicles of the scalp without baldness. Clascoterone is a potent antiandrogen that has demonstrated clinical efficacy in patients with androgenetic alopecia to increase hair growth. Clascoterone has previously been shown to inhibit DHT-induced IL-6 secretion by human dermal papilla cells. Therefore, IL-6 is an HFDPC biomarker that correlates with hair growth.
[0178] Minoxidil is also approved for the treatment of androgenetic alopecia, but there is no information in the literature regarding its effects on IL-6 secretion by dermal papilla cells. In the experimental data presented, Minoxidil demonstrated a mild, non-significant inhibition of IL-6 secretion by HFDPC. Clascoterone at all concentrations tested demonstrated statistically significant inhibition of IL-6 vs. HFDPC treated with DHT. The comparison of clascoterone + DHT vs. clascoterone + DHT + minoxidil showed that the combination was more than additive. In fact, the combination of clascoterone with minoxidil exhibited synergistic efficacy in inhibiting IL-6 secretion by HFDPC.
[0179] Thus, it is evident that patients with androgenetic alopecia should benefit dramatically from the combined treatment of clascoterone plus minoxidil.
