If the subject has been amenorrheic for >or=6 months but <12 months they must have a serum FSH concentration of >or=50 mIU/mL and an estradiol concentration of MALES - subjects must agree to use a double barrier method of contraception during the study and for 3 months after study completion. This may include the following: condom + spermicide or condom + oral hormonal contraception
MALES - have a serum PSA of < or = 4.0 ng/mL or a negative prostate biopsy (no prostate cancer) within 6 months of evaluation

Exclusion Criteria:

Have, in the judgment of the Investigator, a clinically significant concurrent illness or psychological, familial, sociological, geographical or other concomitant condition that would not permit adequate follow-up and compliance with the study protocol
Have ALT/SGOT or AST/SGPT above 1.5 times the upper limit of normal (ULN) without evidence of liver metastases and above 5 times the ULN in subjects with evidence of liver metastases
have alkaline phosphatase greater than 3 times ULN and/or total bilirubin levels above 2 mg/dL at baseline
have biologic agents or kinase inhibitors as part of their first line chemotherapy regimen including, but not limited to bevacizumab (Avastin), gefitinib (Nexavar) and erlotinib (Tarceva)
cardiovascular: uncontrolled hypertension, congestive heart failure or angina

currently taking testosterone, oxandrolone (Oxandrin), testosterone-like agents (such as dehydroepiandrosterone (DHEA), androstenedione, and other androgenic compounds including herbals), or antiandrogens; previous therapy with testosterone and testosterone-like agents is acceptable with a 30 day washout (if previous testosterone therapy was long term depot within the past 6 months, the site should contact the medical monitor for this study to determine appropriate washout period)
currently taking megestrol acetate (Megace), dronabinol (Marinol), medical marijuana (medical cannabis) or any prescription medication intended to increase appetite or treat unintentional weight loss
have a baseline stair climb time >or=30 seconds (mean of two stair climbs)
