A Study to Evaluate Safety and Efficacy of OLX72021 in Healthy Males With Androgenetic Alopecia

A Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Multiple Ascending Dose Phase 1b/2a Study to Evaluate the Safety and Efficacy of OLX72021 in Healthy Males With Androgenetic Alopecia

This study is designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of OLX72021 in medically healthy men with mild to moderate androgenetic alopecia.

This is a Phase 1b/2a double-blind, randomized, placebo-controlled, multiple ascending dose study evaluating the safety, efficacy, and pharmacokinetics (PK) of OLX72021 at a maximum of 2 dose levels. In Phase 1b, evaluation of dose levels will be conducted in a sequential manner with lower dose levels evaluated first in the sequence. Each dose level will be evaluated in a cohort of 12 participants with 9 participants receiving OLX72021 and 3 participants receiving placebo, approximately 24 participants in total. Cohorts may be dosed concurrently in Phase 2a. Each dose level will be evaluated in approximately 134 participants receiving OLX72021 or placebo for Phase 2a.
