August 26, 2022 updated by: Mereo BioPharma

A Phase IIb Multicentre, Double-Blind, Dose-Ranging, Randomised, Placebo-Controlled Study Evaluating Safety and Efficacy of BGS649 in Male Obese Subjects With Hypogonadotropic Hypogonadism

The purpose of this study is to evaluate the safety and efficacy of BGS649 in male obese subjects with hypogonadotropic hypogonadism. All subjects will be treated for a maximum of 24 weeks. Some subjects who complete 24 weeks of treatment will be invited to participate in a 6-month blinded safety extension study (Protocol MBGS206). The study is planned to enroll 268 subjects.

Mean (SD) Change From Baseline in Dual Energy X-ray Absorptiometry (DEXA) Scan T-score by Location at Week 24.
Time Frame: Screening to 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
Mean (SD) Change From Baseline in DEXA Scan Density by Location at Week 24
Time Frame: Screening to 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.
