- Registration Number
- NCT06445075
- Lead Sponsor
- Scholar Rock, Inc.
- Brief Summary
A phase 2 study to evaluate the effects of apitegromab as an adjunctive therapy to GLP-1 agonist therapy in subjects with overweight or obesity
- Detailed Description
This phase 2 randomized, double-blind, placebo-controlled, multicenter study will assess the safety, efficacy, and pharmacokinetics (PK) of apitegromab when used as an adjunctive therapy to GLP-1 agonist therapy in subjects with overweight and obesity and without diabetes. Each subject will receive either semaglutide or tirzepatide, depending upon availability, and will maintain that course throughout the treatment period. In addition, all subjects will be randomized 1:1 to receive either apitegromab or placebo during the treatment period.
