The TRIUMPH-2 phase 3 trial evaluated retatrutide, a novel therapeutic agent, in adults with both obesity and type 2 diabetes through a double-blind, randomized, placebo-controlled study. Treatment with retatrutide led to substantial weight loss and significant improvements in blood sugar control in this patient population. The safety profile was generally consistent with other GLP-1 receptor agonist medications, suggesting retatrutide could be an effective treatment option for managing obesity in people with type 2 diabetes.


This research addresses two major global health challenges simultaneously—obesity and type 2 diabetes—which frequently co-occur and complicate each other's management. The dual benefits on weight reduction and glycemic control could offer clinicians a valuable new tool for treating patients with both conditions, potentially reducing the need for multiple medications and improving long-term health outcomes.


Treatment with retatrutide resulted in substantial improvements in bodyweight and was associated with improvements in glycaemic control in participants with obesity and type 2 diabetes, with a safety profile generally consistent with other molecules with GLP-1 receptor agonism. These results show that retatrutide might be effective for the treatment of obesity in people with type 2 diabetes.
