简要总结
To determine the effects of 12 months of treatment with Androxal on bone mineral density in men with secondary hypogonadism.
详细描述
This study is a phase III single-blind placebo-controlled safety study with a 52 week active dosing period with Androxal. Safety will be assessed by physical and visual acuity exams, slit lamp and fundoscopy eye exams, clinical laboratory tests, DEXA scanning, lean soft tissue assessment (LST), and adverse event reporting. Results will be compared to an age-matched placebo group.

- •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 and confirmed with morning testosterone <300ng/dL measured twice on separate days. One of the two TT levels must be confirmed at baseline. Subjects who fail this criterion will be enrolled in the placebo group.

- •Use of testosterone injection, spironolactone, cimetidine, Clomid, 5α-reductase inhibitors, hCG, androgen, estrogen, anabolic steroid, DHEA, or herbal hormone products during the study
- •Use of Clomid in the past year
- •Uncontrolled hypertension or diabetes mellitus based on the Investigator's assessment at baseline. Subjects treated for Type II diabetes will be allowed into the study. Newly diagnosed diabetics need to be treated for at least 48 hours before being enrolled in the study
- •Clinically significant abnormal findings at screening (Visit 1), based on the Investigator's assessment.
- •A hematocrit >54% or a hemoglobin >17 g/dL
- •Clinically significant abnormal laboratory findings at baseline (Visit 2), based on the Investigator's assessment
- •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.
