Brief Summary:
A phase 2 study to assess the efficacy of bimagrumab alone or in addition to semaglutide to assess efficacy and safety in overweight or obese men and women
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Obesity Obese Overweight or Obesity | Biological: Bimagrumab Drug: Semaglutide Other: Bimagrumab Placebo | Phase 2 |
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 507 participants |
| Allocation: | Randomized |
| Intervention Model: | Factorial Assignment |
| Intervention Model Description: | The study is designed to have three periods. The 48-week core treatment period has 9 treatment arms, with combinations of 3 semaglutide doses (none, 1.0 mg and 2.4 mg) and 3 bimagrumab doses (0, 10 and 30 mg/kg). The core treatment period is then followed by an open-label 24-week treatment extension period during which participants originally assigned to either placebo or bimagrumab 10 mg/kg will switch to bimagrumab 30 mg/kg. All other treatment assignments will remain the same. The extension period is then followed by a 32-week post-treatment period, during which all study treatments will be withdrawn from all arms. |
| Masking: | Double (Participant, Investigator) |
| Masking Description: | In regards to bimagrumab and placebo-bimagrumab, the participants, Investigator and Sponsor will be blinded. Due to semaglutide being pre-filled, packaged and labeled by manufacturer, it is not possible to blind semaglutide. |
| Primary Purpose: | Treatment |
| Official Title: | A Randomized, Double-Blind, Placebo-Controlled Multi-Center Study of Intravenous Bimagrumab, Alone or in Addition to Open Label Subcutaneous Semaglutide, to Investigate the Efficacy and Safety in Overweight or Obese Men and Women |
| Actual Study Start Date : | November 16, 2022 |
| Estimated Primary Completion Date : | May 20, 2024 |
| Estimated Study Completion Date : | June 17, 2025 |

A diagnosis of prediabetes or impaired glucose tolerance managed exclusively with non-pharmacologic approaches (e.g., diet and exercise) is not an exclusion.
- Any chronic infections likely to interfere with study conduct or interpretation such as hepatitis B (HBV), hepatitis C (HCV), or human immunodeficiency virus (HIV). History of hepatitis A or hepatitis C successfully treated is not exclusionary. Active COVID-19 infection.
- Donation or loss of 400 mL or more of blood within 8 weeks prior to initial dosing, or longer if required by local regulation, or plasma donation (> 250 mL) within 14 days prior to the first dose
