Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Mean (SD) Change From Baseline in Prostate Specific Antigen (PSA) to Week 24.	PSA was measured alongside other clinical chemistry parameters at screening, baseline, Visits 1 through 8 and at follow-up.	Baseline, Day 8, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 20 weeks and 24 weeks
Other	Mean (SD) Change From Baseline in Haematocrit to Week 24.	Haematocrit was measured alongside other haematology parameters at screening, baseline, Visits 1 through 8 and at follow-up.	Day 8, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 20 weeks and 24 weeks
Other	Mean (SD) Change From Baseline in Dual Energy X-ray Absorptiometry (DEXA) Scan T-score by Location at Week 24.	Summary of DEXA Scan T-score at Visit 8 (Week 24) in the hip, femoral neck, and lumber spine. DEXA T-score was calculated based on actual measured bone density value and compared to a standard reference range for healthy young adult men.; A bone density scan compares bone density with the bone density expected for a young healthy adult or a healthy adult of the same age, gender and ethnicity. The difference is calculated as a standard deviation (SD) score. The measures between the bone density and the expected value of a young healthy adult is known as the T score.; The World Health Organization (WHO) classifies T scores as follows: above -1 SD is normal; between -1 and -2.5 SD is defined as mildly reduced bone mineral density (BMD) compared with peak bone mass (PBM); at or below -2.5 SD is defined as osteoporosis	Screening to Week 24
Other	Mean (SD) Change From Baseline in DEXA Scan Density by Location at Week 24	Summary of DEXA scan density at Visit 8 (Week 24) in the hip, femoral neck, and lumber spine. Bone density was evaluated with standard procedure for Hologic and General Electric Lunar scanners.	Screening to Week 24
Other	Mean (SD) Change From Baseline in Bone Turnover Markers by Parameter at Week 24.	Descriptive statistics were presented for the following bone turnover marker parameters: type I collagen C-telopeptides, procollagen 1 N-terminal propeptide, osteocalcin, and bone specific alkaline phosphatase.

Normalized total testosterone level was defined as between 300-1000 ng/dL (10.4-35 nmol/L) inclusive. Levels >1000 ng/dL were considered super-physiological outside the normal range. This secondary outcome measure was considered to have been met for a dose if = 90% of subjects in the intent-to-treat (ITT) population had normalisation of total testosterone levels at Week 24.	24 weeks of treatment

Day 8, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 20 weeks and 24 weeks
Secondary	Mean (SD) Change From Baseline in Follicle Stimulating Hormone (FSH) to Week 24.	FSH was measured at baseline, Visit 1 through 8 and follow-up. Baseline was defined as the last non-missing value collected before the first study treatment administration, including unscheduled assessments.	Day 8, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 20 weeks and 24 weeks
Secondary	Descriptive Summary (Geometric Mean [95% CI]) of BGS649 Plasma PK Concentration Values to 24 Weeks.	Plasma PK sampling for BGS649 was performed at Weeks 12 and 24. BGS649 PK plasma concentrations were summarised for the PK population by descriptive statistics.	Week 12 (pre-dose and 1 hour post-dose), week 24 and week 24/End of treatment
Secondary	Descriptive Summary (Geometric Mean [95% CI]) of BGS649 Semen PK Concentration Values at 24 Weeks.	Semen PK sampling for BGS649 was performed at Visit 8 (End of Treatment). BGS649 PK semen concentrations were summarised for the PK population by descriptive statistics.	Week 24 and week 24/End of treatment
