  1. Primary Objectives
    • To assess the efficacy of GTx-024 on physical function
    • To assess the efficacy of GTx-024 on total LBM (overall LBM)
  2. Secondary Objectives
    • To assess the durability of effect of GTx-024 on physical function
    • To assess the durability of effect of GTx-024 on total LBM
    • To assess the change from baseline in physical function in the GTx-024 treatment group compared to placebo
    • To assess the change from baseline in total LBM in the GTx-024 treatment group compared to placebo
  3. Secondary Program Objective
    • To assess the effect of GTx-024 on overall survival (superiority) (pooled data from Protocols G300504 and G300505)
  4. Tertiary Objectives
    • To assess the effect of GTx-024 on healthcare resource utilization
    • To assess the effect of GTx-024 on adherence to chemotherapy treatment plan (i.e. dose intensity)
    • To assess the efficacy of GTx-024 on total body weight
    • To assess the effect of GTx-024 on quality of life as measured by each of the following instruments: FAACT-12, FACIT Fatigue Scale, PROMIS Physical Functioning Short Form 10a, PROMIS Emotional Distress-Depression Short Form 8b, and EQ-5D-5L
    • To assess the minimal clinically meaningful efficacy of GTx-024 on physical function

If the subject has been amenorrheic for >6 months but <12 months they must have a serum FSH concentration of ≥ 50 mIU/mL and an estradiol concentration of ≤ 25 pg/mL. Surgical menopause is defined as bilateral oophorectomy.
  12. 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
  13. MALES - have a serum PSA of ≤ 4.0 ng/mL or a negative prostate biopsy (no prostate cancer) within 6 months of evaluation

Exclusion Criteria
  1. 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
  2. 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
  3. Have alkaline phosphatase greater than 3 times ULN and/or total bilirubin levels above 2 mg/dL at baseline
  4. Have biologic agents or kinase inhibitors as part of their first line chemotherapy regimen including, but not limited to bevacizumab (Avastin), gefitinib (Iressa) and erlotinib (Tarceva)
  5. Cardiovascular: uncontrolled hypertension, congestive heart failure or angina

  7. Positive screen for Hepatitis B consisting of HBsAg (Hepatitis B Surface Antigen), unless subject was diagnosed > 10 years prior to enrollment and no evidence of active liver disease
  8. Positive screen for anti-HCV (Hepatitis C Antibody), hepatitis A antibody IgM, or HIV
  9. 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)
  10. Currently taking megestrol acetate (Megace), dronabinol (Marinol), medical marijuana (medical cannabis) or any prescription medication intended to increase appetite or treat unintentional weight loss (any such products must be discontinued prior to randomization).
  11. Have a baseline stair climb time ≥ 30 seconds (mean of two stair climbs)
  12. Have active cancer, other than NSCLC or non-melanoma carcinoma of the skin, within previous two years.
