Study Summary

The purpose of ZA-302 is to determine the effects of Androxal on morning testosterone and reproductive status in younger overweight men with acquired hypogonadotropic hypogonadism (confirmed morning T\<300 ng/dL) and normal sperm concentration, compared to changes with placebo. Subjects must not have previously been treated with testosterone products within the last 6 months.

Primary Outcome

Proportion (percent) of subjects with average serum concentration (Cavg) for T in the normal range (300 - 1040 ng/dL) after 12 weeks of treatment. Cavg was calculated as the numerical average of 24-hour serial testosterone assessments at 0, 1, 2, 3, 4, 6, 8, 12, 16 and 24 hours after dosing. If the lower limit of the 95% confidence interval for the Androxal treatment group at Week 12 is at least 67%, then the coprimary endpoint based on the Cavg for testosterone would have been achieved.
