Clinical Trial Summary

This study is researching experimental drugs called trevogrumab and garetosmab (called "study drugs") in combination with another drug, semaglutide (Wegovy®). Part A of the study, the sponsor is only researching trevogrumab. Part B of the study the sponsor is researching trevogrumab, garetosmab, and Wegovy either alone or in different combinations with each other. Part A of the study is focused on healthy participants. Part B 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 of the study is to see how safe and effective the study drug is when combined with Wegovy.

Parts A and B 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)

Description:

Part A Healthy Volunteers

Part B (starts after treatment for Part A has completed) Participants with Obesity

Secondary	Change in physical function domain (5 items) score of Impact of Weight on Quality of Life-Lite for Clinical Trials (IWQoLLite- CT)	Part B IWQOL-Lite-CT version 3 is a 20-item COA instrument used to assess the impact of body weight changes in obesity studies on patient's physical and psychosocial functioning in three composite scores (physical function, physical and psychosocial) and a total score. This endpoint assesses the 'physical function score'. The scores range between 0-100 where higher scores indicate a better quality of life. A positive change score indicates an improvement since baseline.	Baseline to week 26
