Estimated Enrollment: 300
Study Start Date: November 2012
Study Completion Date: April 2014
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Androxal
Androxal (enclomiphene citrate) 12.5 mg, once daily, oral capsule. Subjects will be up-titrated to 25 mg if testosterone levels remain below 450 ng/dL at visit 2.
Drug: Androxal
Other Name: enclomiphene citrate

Detailed Description:
This study is an open-label, multi-center Phase 3 extension study to evaluate the safety on continued treatment with Androxal in subjects who completed either ZA-301 or ZA-302. The study requires 6 study visits (1 for an eye exam) and is approximately 7 months in duration. Subjects will be treated for 26 weeks, starting at a daily dose of 12.5 mg. At Visit 2 (Week 6) subjects who do not achieve morning T values ≥450 ng/dL will be up-titrated to 25 mg. Safety will be assessed by physical and visual acuity exams, slit lamp and fundoscopy, refraction eye exams, clinical laboratory tests and adverse event reporting.
