A 6-Month Phase 3, Multicenter, Prospective, Randomized, Double-Blind, Vehicle-Controlled Study, to Evaluate the Efficacy and Safety of Topically Applied Clascoterone (Cortexolone 17A-Propionate) Solution for the Treatment of Androgenetic Alopecia in Males, Followed by a 6-Month Single-Blind Treatment with Clascoterone or Vehicle BID Solution. (SCALP 1)


We are studying a new topical drug, Clascoternone, to treat adult males who have male pattern baldness. Participants randomly (by chance) receive the drug or an inactive solution that is applied to the area of hair loss twice a day for six months. We will compare the effectiveness and side effects of the two groups. Men who have regrowth of hair may also participate in a second six-month treatment to look at the long-term effectiveness of the drug.
