[0001] The present disclosure provides a liquid composition comprising about 1% w / v to about 20% w / v spironolactone and / or canrenone, about 1% w / v to about 20% w / v minoxidil, about 10% w / v to about 60% w / v of aliphatic solvents (e g., a C4-C14 aliphatic solvents), a penetration enhancer, and about 1% w / v to about 30% w / v polyethylene glycol, wherein the composition does not comprise C1-C3 alcohols or propylene glycol. The disclosure further provides a method of treating hair loss in a human, the method comprising applying the composition to the scalp.BACKGROUND
[0002] Androgenetic alopecia (AGA) is a common form of hair loss in both men and women that affects 80% of men and 50% of women by the age of seventy. AGA consists of a characteristic receding frontal hairline in men and diffuse hair thinning in women with frontal hairline retention. The condition is primarily mediated by 5-alpha-reductase and dihydrotestosterone (DHT) which causes hair follicles to undergo miniaturization and shortening of successive anagen cycles.. The extent and intensity of hair loss varies greatly between frontotemporal recession and residual occipital band, and patients may go through several stages in between.
[0003] Topical minoxidil, initially developed as a potent peripheral vasodilator agent for the treatment of severe refractory hypertension, is the mainstay treatment approved by the U. S. Food and Drug Administration (FDA) for androgenetic alopecia and is used as an off-label treatment for other hair loss conditions including alopecia areata and scarring alopecia. The mechanism by which minoxidil promotes hair growth is not fully understood. Minoxidil is an adenosine 5'-triphosphate-sensitive potassium channel opener causing hyperpolarization of cell membranes. Theoretically, by widening blood vessels and opening potassium channels, it allows more oxygen, blood, and nutrients to the follicles. Moreover, minoxidil contains a nitric oxide moiety and may act as a nitric oxide agonist causing follicles in the telogen phase to shed, which are then replaced by thicker hairs in a new anagen phase. In evaluating minoxidil's effectiveness in stimulating hairregrowth in men, investigators found that a topical 5% minoxidil solution was very effective in 15.9% of patients, effective in 47.8%, moderately effective in 20.6%, and ineffective. 15.7%.
[0004] Currently, topical minoxidil for treatment of AGA is available as a 2% solution or a 5% foam. However, these marketed minoxidil formulations have several issues. Firstly, in order to be effective, minoxidil needs to be converted by the enzyme sulfotransferase into its active form, minoxidil sulfate. Studies indicate that approximately 30-40% of women do not have sufficient levels of sulfotransferase in their hair follicles, which may lead to a reduced response to minoxidil treatment in women specifically and may explain why a significant portion of women do not experience the same effects from using minoxidil for hair loss as men do.
[0005] Secondly, minoxidil is poorly soluble in solution and concentrations greater than 5% tend to be unstable and crystallization (or powdering) of minoxidil occurs on the scalp when the solvent evaporates. The 5% foam formulation leaves a residue in hair which makes hair unmanageable and therefore is not preferred by many women. Solution formulations comprising minoxidil often contain propylene glycol to solubilize minoxidil. Evidence suggests that patients treated with alcohol-based minoxidil topical solutions that contain propylene glycol, e.g., compositions comprising C1-C3 alcohols, have been reported to cause local irritation of the scalp, pruritus, itching, burning, dryness, and redness and 11% of patients reported allergic contact dermatitis after using alcohol-based minoxidil solutions. Further, topical application of minoxidil results in variable systemic absorption depending on various factors, including the vehicle in the formulation, the area of application and skin status (absorption is increased if the scalp is abraded or inflamed). On average, only 1.4% of the active ingredient is systemically absorbed after topical application to the scalp.
[0006] Spironolactone is an anti-androgen that works by reducing levels of androgens that contribute to hair loss in women, particularly in cases of androgenetic alopecia. However, the systemic side effects of spironolactone when administered orally restrict its clinical application. When administered orally, spironolactone rapidly metabolizes in the liver into a number of metabolites including canrenone. Spironolactone and its metabolites can cause diuretic effects, menstrual irregularity, breast tenderness and enlargement, dizziness, headaches, nausea and vomiting in women. In men, oral administration of spironolactone and its metabolites can cause adecrease of libido, impotence and gynecomastia. Because of this, spironolactone is currently prescribed off-label to females for acne but is not prescribed to males. Additionally, oral administration of the recommended dosage of 50 mg - 100 mg spironolactone twice a day for the treatment of acne exposes patients to systemic adverse events for an indication that is local.
[0007] In order to bypass the hepatic first pass metabolism of spironolactone and prevent the adverse effects of spironolactone and its metabolites that occur when spironolactone is administered orally, topical administration for the delivery of spironolactone has been attempted. For example, U. S. Patent No. 4,543,351 reports a spironolactone-containing composition for combating acne in the form of a cream to be applied to human skin. US Patent No 8,003,690 describes a topical nanoparticulate spironolactone formulation comprising nanoparticles having a mean diameter in the range of from about 300 nm to about 900 nm. A 5% spironolactone topical lotion and cream have been used to treat grade II acne (Kim, 2012). Sebum secretion was treated with a 5% spironolactone gel (Yamamoto, 1996). However, creams, gels and lotions can be difficult to apply, are inconvenient, and can involve a messy application process and are known for inadvertent transfer of spironolactone to others who may come in contact with these formulations. Additionally, spironolactone and minoxidil exert challenges when being formulated, including stability challenges, permeation challenges and intrinsic solubility of the spironolactone and minoxidil in solvents. Further, none of the previous treatment methods have been demonstrated to be effective and safe in treating acne in both men and women.SUMMARY OF THE INVENTION

[0030] The present disclosure relates to a liquid composition comprising spironolactone or canrenone and minoxidil and methods suitable for the treatment of male and female pattern hair loss, wherein the composition does not comprise C1-C3 alcohols. In some embodiments, the disclosure provides a liquid composition comprising a combination of spironolactone and minoxidil. Spironolactone and minoxidil compositions have been used previously in the forms of topical lotions, sprays and gels. However, the present disclosure provides for a new composition comprising both spironolactone and minoxidil that do not contain ethanol or propylene glycol, which dry out the skin and cause the irritation implicated with minoxidil formulations, and that can be applied and rubbed into hair without leaving behind a residue. The present disclosure provides a liquid composition suitable for application to the skin without undue irritation, while maintaining the physical stability, chemical stability and efficacy of the spironolactone (and / or canrenone) and minoxidil. Applicant has found a liquid composition in which the spironolactone (and / or canrenone) and minoxidil remains stable over an extended period of time, while still allowing for topical penetration of spironolactone (and / or canrenone) and minoxidil within the skin. The present disclosure also provides for a liquid composition that does not contain C1-C3 alcohols and in which the spironolactone and minoxidil does not precipitate when stored for an extended period of time.
[0031] In some embodiments, the liquid compositions described herein can be sprayed directly on the skin surface, and do not need to be spread over the skin by touching with fingers or with use of a separate applicator. In some embodiments, drug absorption into the skin is rapid and occurs in less than four hours. In some embodiments, during solvent evaporation, the excipientsincluded in the sprayable liquid compositions can prevent recrystallization of spironolactone, canrenone and minoxidil, a feature that can be important for its penetration of the skin or scalp. In some embodiments, the spironolactone, canrenone and minoxidil in the liquid composition described herein do not crystallize when the composition is applied to the skin. In some embodiments, direct application to the skin via a liquid composition that is sprayed provides for increased convenience, and lower transmission of the spironolactone canrenone and minoxidil to the hands / fingers or other body parts for which it is not needed. In some embodiments, the sprayable liquid compositions described herein can be applied quickly. In some embodiments, the sprayable liquid compositions described herein can be applied quickly over a large area of the skin or scalp.

[0078] Any fragrance suitable for application to the hair can be used herein including a wide variety of fragrances and perfumes that are known to those skilled in the art. In some embodiments, the amount of fragrance can be effective for providing a noticeable aroma to the composition, or for masking undesired aroma of the composition. In some embodiments, the fragrance does not impart excessive stinging to the skin, especially to broken or irritated skin.
[0079] Typical fragrances are described in Arctander, Perfume and Flavour Chemicals (Aroma Chemicals), Vol. I and II (1969, Allured Publishing Corporation, 1969 (ISBN0931710375, 9780931710377), and Arctander, Perfume and Flavor Materials of Natural Origin (1994, by Allured Pub Corp) (ISBN 0931710367; ISBN13: 9780931710360). Fragrance used in the present composition can also contain solubilizers, diluents, or solvents which are well known in the art.
[0080] High viscosity topical minoxidil, spironolactone and / or canrenone formulations, e.g., creams, lotions and gels, require application to the scalp with the palm or fingers of the hand of the user, and thus these types of formulations are associated with a significant risk for secondary minoxidil and, spironolactone and / or canrenone exposure. The present claims feature a liquid composition, i.e., low viscosity compositions, which can be applied directly to the skin in an amount effective via a cream, gel foam or spray. Such sprayable liquid composition are useful and convenient in delivering the required dosage or minoxidil and, spironolactone and / or canrenone needed for the treatment of male and female pattern hair loss. In some embodiments, the “sprayable liquid composition” has low viscosity (about 15 cPs to about 45 cPs) and can be administered in smaller volumes, i.e., in a volume less than 500 pL per actuation. In some embodiments, the sprayable liquid composition has a viscosity suitable for administering via an aerosol spray and / or a mist. For example, in some embodiments, the sprayable liquid composition has a viscosity of less than 200 cPs, less than 100 cPs, less than 50 cPs or less than 30 cPs at room temperature. In some embodiments, the sprayable liquid formation has a viscosity of about 1 cp to about 10 cPs, about 5 cPS to about 20 cPs or about 20 cPs to about 30 cPs at room temperature. In some embodiments, the sprayable liquid composition has a viscosity of about 5 cPs to about 15 cPs. As used throughout the present disclosure, viscosity is measured at standard conditions, e.g., 1 atm pressure and 25 °C temperature.
[0081] The liquid composition of the present disclosure can be administered by means to known in the art.

In some embodiments, the spray container further comprises a dose indicator. In someembodiments, the spray container comprises a propellant. In some embodiments, the spray container comprises an amount of the sprayable liquid composition sufficient for a single administration of the composition. In some embodiments, the spray container comprises an amount of the sprayable liquid composition sufficient for two administrations of the composition. In some embodiments, the spray container comprises an amount of the sprayable liquid composition sufficient for three or more administrations of the composition.
[0082] In some embodiments, the invention comprises a device that compartmentalizes the ingredients until time of application. For example, in one embodiment, one or more ingredients are separated from other ingredients until a user combines them. Such separate delivery helps to ensure that the two fluids are not mixed prematurely, and to ensure that minimal mixed composition is stored within the dispensing device, to ensure high efficacy. In some embodiments, a dual chamber or multi-chamber device is used to hold and / or apply the sprayable liquid composition. In some embodiments, the present disclosure provides a dual chamber device used to apply the compositions described herein. In some embodiments, the dual device chamber comprises a first and second chamber. In some embodiments, the first and second chamber each comprise different compositions. In some embodiments, the compositions in each chamber are kept separate until mixing during application either by concomitant actuation of the sprays from each of the chambers or by application from a pad when a seal is broken between pouches containing each formulation. Separate dip tubes may be provided to pull liquid from the separate chambers, each with its own separate pump. Each pump may deliver the separate compositions to a nozzle (e.g., a spray nozzle) of the device through separate delivery tubes (e.g., from the pumps to the nozzle). Such separate delivery tubes may be preferred for limiting mixing of the components before use. In another embodiment, a single delivery tube from the two pumps may be provided, e.g., where the volume of mixed composition that may be present within such a delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics.
[0083] In some embodiments, the first chamber comprises a first composition comprising 1% w / w to 10% w / w spironolactone, about 15% w / w to 20% w / w ethyl acetate and about 10% diisopropyl adipate. In some embodiments, the second chamber comprises a second composition comprising about 50% w / w to about 60% w / w dimethyl Isosorbide, about 4% to 7% isopropyl myristate and about 1.5 w / w polyethylene glycol 400. In some embodiments, the dual chamberdevice comprises a first chamber comprising a first composition comprising 1% w / w to 10% w / w spironolactone, about 15% w / w to 20% w / w ethyl acetate and about 10% di-isopropyl adipate, and a second chamber comprising a second composition comprising about 50% w / w to about 60% w / w dimethyl Isosorbide, about 4% to 7% isopropyl myristate, and about 1.5 w / w polyethylene glycol 400, wherein the dual chamber device is suitable for providing a spray comprising the composition. In some embodiments, the first composition further comprises polyvinylpyrrolidone. In some embodiments, the contents of the first and second chambers are mixed during spraying of the composition onto human skin.
[0084] Particular embodiments of the present disclosure may include the administration of one or more additional active agents with the administration of minoxidil and, spironolactone and / or canrenone as described herein. The identity of the additional active agent(s) will be largely dependent on the nature of the underlying condition being treated (e.g., the addition of a moisturizer such as niacinamide may be appropriate in the treatment of skin dryness and the addition of agents such as finasteride and dutasteride may be appropriate in the treatment of hair loss in males and females. In some embodiments, the compositions of the device may include additional active agents that are effective in promoting hair growth or preventing hair loss in the treatment of male pattern baldness and / or ameliorating dry skin, rashes, facial flushing, raised red bumps, skin and skin sensitivity in the treatment of skin disorders.
[0085] Suitable additional active agents include, but are not limited to, minoxidil sulfate, or another salt form such as chloride, carbonate, nitrate, etc., finasteride, and niacinamide. In some embodiments, the additional active agent is finasteride, dutasteride, niacinamide or combinations thereof.
[0086] In some embodiments, the additional active agent is about 0.1% to about 10% of the liquid composition. In some embodiments, the additional active agent is about 1% w / w to about 10% w / w minoxidil, about 0.1% w / w to about 1.0% w / w finasteride or dutasteride, about 2% w / v to about 10% w / v niacinamide, or any combination thereof. In some embodiments, additional active agent is present in the same sprayable liquid composition as the spironolactone and / or minoxidil. For example, the additional active agent, e g., minoxidil can be in the same composition as spironolactone, and the composition can be the same chamber of the dispensing system. Insome embodiments, the additional active agent is in a sprayable liquid composition that is distinct from the sprayable liquid composition comprising the spironolactone. For example, the additional active agent, e.g., minoxidil, can be in a first composition in first chamber of a dispensing system, and the spironolactone can be in a second composition in a second chamber in the dispensing system. Thus, it is envisioned by the present disclosure that the both the spironolactone and the additional active agent can be applied from the same dispensing system independently of whether the spironolactone and the additional active agent are in the same sprayable liquid composition or in distinct sprayable liquid compositions.
[0087] In some embodiments, oral administration of spironolactone to a population of subjects have been reported to result in at least one adverse effect in a statistically measurable subpopulation of subjects. Reported adverse effects and their incidence rates from clinical studies can include: (i) menstrual irregularities (oligomenorrhea, amenorrhea, breakthrough bleeding), (ii) 15-30 % of women; breast tenderness or mastalgia: 5-15 %; (iii) Dizziness or hypotension: 5-10 %, (iv) Gastrointestinal upset (nausea, abdominal cramping): 3-8 %, (v)Hyperkalemia: rare in healthy young women (<1 %), but monitoring is still recommended, especially if other risk factors are present.
