Repros Therapeutics Inc (RPRX) announced positive top-line data on its secondary hypogonadism candidate, Androxal, from a pivotal phase III study. Repros had initiated two identical, 17-week, double-blind ZA-304 and ZA-305 studies to compare the safety and efficacy of Androxal with a testosterone replacement therapy (topical gel) and placebo in restoring and maintaining testicular function.
The ZA-305 study was the first of the two identical pivotal studies. In the study, Androxal demonstrated superiority on several assessments including the two co-primary endpoints and several secondary endpoints. In patients receiving Androxal, percent change in sperm concentration from baseline was found to be unchanged. In contrast, in the testosterone gel arm, patients experienced a median 33% decrease from their baseline concentration.
Additionally, a significantly higher proportion of men exhibited mean sperm concentration ≥ 10 million/mL in the Androxal arm as compared to testosterone gel and placebo.
