Cioteronel

Cioteronel (INN, USAN) (developmental code name CPC-10997; former tentative brand names Cyoctol, X-Andron) is a nonsteroidal antiandrogen (NSAA) that was never marketed.[1][2][3] It was under development between 1989 and 2001 for the topical treatment of androgenetic alopecia (male pattern baldness) and acne and for the oral treatment of benign prostatic hyperplasia; it reached phase III clinical trials for acne and phase II studies for androgenetic alopecia, but was ultimately discontinued due to poor efficacy.[3][4]
