A Study to Test if Trevogrumab or Trevogrumab With Garetosmab When Taken With Semaglutide is Safe and How Well They Work in Adult Patients With Obesity for Weight Loss, Fat Loss, and Lean Mass Preservation (COURAGE)
A Randomized, Double-Blind Study of The Efficacy and Safety of Trevogrumab, With or Without Garetosmab, in Addition to Semaglutide in Patients With Obesity
This study is researching experimental drugs called trevogrumab and garetosmab (called "study drugs") in combination with another drug, semaglutide (Wegovy®). This study will be done in 3 parts, Part A, Part B, and Part C where different study drugs will be tested.
Part A of the study is focused on healthy participants. Part B and C of the study is focused on participants with obesity.
The aim of Part A of the study is to see how safe and tolerable the study drug is in healthy participants. The aim of Part B and Part C of the study is to see how safe and effective the study drug is when combined with Wegovy.
Parts A, B, and C of the study are looking at several other research questions, including:
- What side effects may happen from taking the study drug
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
