Summary

The purpose of ZA-301 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.

Eligibility Criteria

Inclusion Criteria

  • Overweight (BMI 25 to 42 kg/m2 inclusive) males age 18 to 60 inclusive
  • All clinical laboratory tests within normal ranges (any clinically significant deviation of laboratory results will require approval of sponsor)
  • Previously or concurrently diagnosed as having secondary hypogonadism characterized as having 2 consecutive morning testosterone assessments 54% or a hemoglobin >17 g/dL (sponsor may approve enrollment of subjects with hemoglobin up to 17.5 g/dL if the subject is at a location with a high elevation)
  • Use of an investigational drug or product, or participation in a drug or medical device research study within 30 days prior to receiving study medication.
  • Known hypersensitivity to Clomid
  • Symptomatic cataracts (nuclear sclerosis cataract or cortical cataract grade > 2 based on 0-4 scale or any trace of posterior subcapsular cataract)
  • Abnormal fundoscopy exam such as central retinal vein occlusion
  • Any condition which in the opinion of the investigator would interfere with the participant's ability to provide informed consent, comply with study instructions, possibly confound interpretation of study results, or endanger the participant if he took part in the study
  • Irreversibly infertile or compromised fertility (cryptorchism, Kallman Syndrome, primary hypogonadism, vasectomy, or tumors of the pituitary)
  • Current or history of breast cancer
  • Current or history of prostate cancer or a suspicion of prostate disease unless ruled out by prostate biopsy, or a PSA>3.6
  • Presence or history of known hyperprolactinemia with or without a tumor
  • Chronic use of medications such as glucocorticoids
  • History of drug abuse or chronic narcotic use including methadone
  • A recent history of alcoholism or illegal substance or steroid abuse ( 21 drinks per week)
  • Subjects with known history of HIV and/or Hepatitis C
  • Subjects with end stage renal disease
  • History of liver disease (including malignancy) or a confirmed AST or ALT >3 times the upper limit of normal
  • History of myocardial infarction, unstable angina, symptomatic heart failure, ventricular dysrhythmia or know history of QTc interval prolongation
  • History of cerebrovascular disease
  • History of venous thromboembolic disease (e.g. deep vein thrombosis or pulmonary embolism)
  • History of erythrocytosis or polycythemia
  • Subjects with cystic fibrosis (mutation of the CFTR gene)
  • Subjects unable to provide a semen sample in a sponsor-approved clinic
  • Enrollment in a previous Androxal study
