A Phase II, 28-Day, Randomized, Parallel-Group, Open-Label Study Evaluating the Efficacy and Safety of Twice Daily Oral Doses of Testosterone (150-400mg) Co-administered With 0.25mg Dutasteride Compared With 400mg Testosterone Alone and 0.25mg Dutasteride Alone in the Treatment of Hypogonadism
The combination of testosterone and dutasteride is intended for use in hypogonadal men. This
study will evaluate the effect of 28-day repeat dosing of this combination with varying BID
doses of testosterone (T), in combination with a fixed BID dose of dutasteride (D), as well
as a testosterone alone arm, on T and D levels in the blood. The rationale is to look for the
effects of each compound on the other, and to look for any safety problems that may result
when the 2 drugs are given together.
