A Trial to Evaluate Efficacy and Safety of Maridebart Cafraglutide in Adults Living With Elevated Liver Fat and Obesity or Overweight

Официальное название

Phase 2b Randomized, Double-blind, Placebo-controlled Trial to Evaluate the Efficacy, Safety and Tolerability of Maridebart Cafraglutide in Adult Participants Living With Elevated Liver Fat and Obesity or Overweight

Обзор

The main objective of this trial will be to determine whether maridebart cafraglutide is superior to placebo on reduction in liver fat content and body weight in participants living with obesity or overweight and elevated liver fat content, when administered in conjunction with reduced-calorie diet and increased physical activity.
