A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Event-Driven Study to Investigate the Effect of Retatrutide on the Incidence of Major Adverse Cardiovascular Events and Major Adverse Kidney Events in Participants With Body Mass Index ≥27 kg/m2 and Atherosclerotic Cardiovascular Disease and/or Chronic Kidney Disease
Eli Lilly and Company
Phase 3 cardiovascular and kidney outcomes trial testing retatrutide in adults with BMI ≥27 kg/m² and atherosclerotic cardiovascular disease and/or chronic kidney disease. Enrollment targets 10,000 participants in a double-blind, placebo-controlled, event-driven design running approximately 5 years through February 2029. Eli Lilly advances retatrutide into major outcomes territory, competing directly with established GLP-1 agents that already hold cardiovascular indications like Wegovy and future tirzepatide expansions. This represents the largest cardiovascular outcomes program for any triple agonist to date.
Strategic Signal
Eli Lilly positions retatrutide for cardiovascular outcomes before obesity approval, mirroring Novo's successful Wegovy MACE expansion strategy in March 2024. The 10,000-patient scale signals Lilly's confidence in competing against established GLP-1 cardiovascular claims from Wegovy and potential future tirzepatide MACE data. US CMS and EU HTA bodies will compare retatrutide's risk reduction profile against existing GLP-1 cardiovascular evidence when evaluating reimbursement tiers. The dual MACE/kidney endpoint combination targets high-value patient populations already covered by competitor agents.
