The purpose of this study is to test whether survodutide helps people living with obesity or overweight and with a confirmed or presumed liver disease called non-alcoholic steatohepatitis (NASH) to reduce liver fat and to lose weight

Individuals with obesity and a history of heart or kidney-related disease will be eligible for participation. Study participants will have a 50:50 chance to be randomly assigned to either the treatment (retatrutide) or control (placebo) group. Retatrutide is currently considered an investigational medication as it has not been approved by the FDA for the treatment of obesity or any other medical condition at this time. Study participation will last approximately 5 years and begin with a screening period to ensure correct patient selection. Research clinic visits will occur every 4 weeks initially and then every 12 weeks. Some visits may be completed virtually through telehealth or by phone. Study procedures include but are not limited to: blood draws, questionnaires, self injection of study medication, medical history review, vital signs, and electrocardiogram. The medication will be injected subcutaneously once a week. The medication's purpose is to facilitate weight loss and decrease a subject's risk for heart or kidney related disease progression or events.
