  • Diabetic Parameters [ Time Frame: 26 weeks ]
    Changes in HbA1c, fasting plasma glucose (FPG), insulin, and homeostasis model assessment-insulin resistance (HOMA-IR) for those subjects with Type II diabetes

  • Change in weight and body mass index (BMI) [ Time Frame: 26 weeks ]

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.

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

• Successful completion of either ZA-301 or ZA-302

Exclusion Criteria:

• Any condition which, in the opinion of the Investigator, would make the Subject an unsuitable candidate for enrollment in the study
