Clascoterone skin care

Clascoterone (cortexolone 17α-propionate, CB-03-01) is a novel antagonist of androgen receptors. It binds to androgen receptors with high affinity. By competing with androgens for binding to androgen receptors, clascoterone works by blocking the androgen receptor signalling cascades that promote acne pathogenesis, such as sebaceous gland proliferation, excess sebum production, and inflammatory pathways. In August 2020, FDA approved clascoterone for the first-in-class topical treatment of acne (acne vulgaris) in male and female patients 12 years and older. Clascoterone is also being investigated as a novel treatment for androgenetic alopecia.

Pharmacodynamics

Clascoterone exerts anti-androgenic effects by working as an antagonist at androgen receptors (ARs) expressed throughout the skin, including sebaceous glands, sebocytes, and dermal papilla cells.  Clascoterone blocks the effects of testosterone and dihydrotestosterone (DHT), which are androgens that bind to the ARs and contribute to the development of androgen-dependent conditions such as acne and alopecia. In vitro, the antiandrogenic effects of clascoterone in human primary sebocytes occurred in a dose-dependent manner. Clascoterone mediates selective topical activity by mainly targeting androgen receptors at the site of application. It has limited systemic effects.
