Brief Summary:
ZA-300 is meant to determine the safety profile of Androxal (enclomiphene citrate) in men with secondary hypogonadism.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Secondary Hypogonadism | Drug: Androxal | Phase 3 |
This study is a phase III, open label safety study with a six month active dosing period. All subjects will be started at 12.5 mg Androxal and titrated to 25 mg if needed. Safety will be assessed by physical and visual acuity exams, slit lamp eye exams, clinical laboratory tests and adverse event reporting.

Criteria
Inclusion Criteria:
- Secondary hypogonadal males between the ages of 18 and 65
- Men currently using topical testosterone products should wash-out for at least 7 days before Visit 1.
- All clinical laboratory tests within normal ranges (any clinically significant deviation of laboratory results will require approval of sponsor)

- LH < 15mIU/mL (at Visit 1 only)
- Ability to complete the study in compliance with the protocol
- Ability to understand and provide written informed consent.
Exclusion Criteria:
- Use of an injectable pelleted testosterone within 6 months prior to study (men currently on topical testosterone products may be enrolled in the study after a 7-day washout period).
- Use testosterone injection, spironolactone, cimetidine, Clomid, 5α-reductase inhibitors, hCG, androgen, estrogen, anabolic steroid, DHEA, or herbal hormone products during the study

- Symptomatic cataracts (nuclear sclerosis cataract or cortical cataract grade > 2 based on 0-4 scale or any trace of posterior subcapsular cataract)
- 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, 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
