    Urology Product Preview: Testosterone agent meets efficacy endpoint in phase III studies

    Testosterone agent meets efficacy endpoint in phase III studies

    Clarus Therapeutics, Inc. recently presented phase III clinical data from two studies that it says support the safety and efficacy of oral testosterone undecanoate (REXTORO) for testosterone replacement therapy in men with hypogonadism. Each trial differed in design, dose-titration algorithm, and duration. Each demonstrated T replacement, and with the revised dose-titration algorithm, the maximum serum T concentration was comparable to other T replacement therapies. The agent met the efficacy endpoint in both studies, said Clarus Therapeutics CEO Robert E. Dudley, PhD, in a press release. The studies were presented at the International Congress of Endocrinology and the Endocrine Society’s Annual Meeting and Expo in Chicago.

    FDA proposes co-primary endpoints for testosterone agent trials

    The FDA has provided additional guidance to Repros Therapeutics regarding primary endpoints for the studies of Androxal that the company is currently conducting. The studies are comparing Androxal to the leading approved testosterone gel and placebo. Androxal is being developed for men of reproductive age with low testosterone due to secondary hypogonadism. The FDA proposed three co-primary endpoints: percentage change from baseline in sperm concentration comparing Androxal to the leading U.S. testosterone replacement therapy; proportion of men obtaining a testosterone level in the normal range; and percentage of men who exhibit sperm ≥10 million/mL at the end of 16 weeks of dosing and testosterone in the normal range, comparing Androxal to a testosterone gel as well as comparing Androxal to placebo.
