Cleanse the affected area gently. After the skin is dry, apply a thin uniform layer of Clascoterone cream twice per day, in the morning and the evening, to the affected area. Avoid accidental transfer of Clascoterone cream into eyes, mouth or other mucous membranes. If contact with mucous membranes occurs, rinse thoroughly with water. Clascoterone cream is for topical use only. This cream is not for ophthalmic, oral or vaginal use.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In two identical multicenter, randomized, double-blind, vehicle-controlled trials, 1421 subjects 12 years and older with facial acne vulgaris applied Clascoterone cream or vehicle twice daily for 12 weeks. Overall, 62% of the subjects were female, and 38% were male, 91% of the patients were Caucasian, and the mean age was 19.7 years.

Local skin reactions (edema, erythema/redness, pruritus, scaling/dryness, skin atrophy, stinging/burning, striae rubrea, telangiectasia) were observed during the 12-week treatment and occurred in a similar percentage of subjects treated with vehicle.

Clascoterone cream is an androgen receptor inhibitor indicated for the topical treatment of acne vulgaris in patients 12 years of age and older.

Acne is a multifactorial skin condition characterized by excess sebum production, epithelial hyperkeratinization, proliferation of the skin commensal bacteria, and inflammation. Circulating and locally synthesized natural ligands, testosterone and dihydrotestosterone (DHT), serve as causative factors in both males and females. Upon binding of DHT, the DHT-androgen receptor complex dimerizes and translocates to the nucleus where it promotes the transcription of genes involved in acne pathogenesis, including proliferation and differentiation of sebocytes, excess sebum production, and inflammatory cytokine production. Clascoterone is a potent antagonist at ARs and competes for androgens in binding to the receptor, thereby inhibiting downstream signalling of ARs that promote acne.

Androgenetic alopecia is also an androgen-dependent and highly genetic condition. Dihydrotestosterone (DHT) binds to ARs expressed on dermal papilla cells (DPC) in the scalp to induce AR-mediated transcription of genes that contribute to androgenic alopecia. By blocking the interaction between DHT and aARs, clascoterone inhibits AR-regulated transcription and DHT-induced IL-6 synthesis.

Local Skin Reactions: Clascoterone cream may induce local irritation (erythema/redness, pruritus, scaling/ dryness). Concomitant use with other potentially irritating topical products (medicated or abrasive soaps and cleansers, soaps and cosmetics that have a strong drying effect and products with high concentrations of alcohol, astringents, spices or lime) should be limited. The product should not be applied to cuts, abrasions, eczematous or sunburned skin.

Hypothalamic-pituitary-adrenal (HPA) Axis Suppression: Hypothalamic-pituitary-adrenal (HPA) axis suppression was observed and may occur during or after treatment with clascoterone. In the PK trial, all subjects returned to normal HPA axis function at follow-up 4 weeks after stopping treatment. Conditions which augment systemic absorption include use over large surface areas, prolonged use, and the use of occlusive dressings. If HPA axis suppression develops, an attempt should be made to withdraw the drug. Pediatric patients may be more susceptible to systemic toxicity.
