• Research summary

  In the UK obesity and overweight in adults is a serious health concern that increases the risk of many other health conditions. This phase 3 study is being done to see if maridebart cafraglutide [MariTide (formerly AMG 133)] is safe, can lower body weight, and can improve weight-related conditions for people who have obesity or are overweight, but do not have type 2 diabetes. The study will see if MariTide is better than placebo (a substance that has no medical effect but looks like MariTide) in reducing body weight and whether it causes any side effects. This study will also look at what doses of MariTide are safe for people to take. Participants will be in this study for a total of 88 weeks (about 2 years) including:
  - an up to 28 day (4 week/1 month) screening period
  - a 72 week (about 1.5 years) treatment period
  - and a 12 week (3 months) safety follow-up period
