The Effect of Retatrutide Once Weekly on Cardiovascular Outcomes and Kidney Outcomes in Adults Living With Obesity (TRIUMPH-Outcomes)

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

Brief summary

The main purpose of this study is to determine if retatrutide can significantly lower the incidence of serious heart-related complications or prevent the worsening of kidney function. The trial will enroll adults with body mass index 27 kg/m\^2 or higher and Atherosclerotic Cardiovascular Disease and/or chronic kidney disease. The study will last for about 5 years. Participants will have up to 27 clinic visits with the study doctor.

Inclusion criteria

* Participants may be without type 2 diabetes (T2D), or with T2D if their hemoglobin A1c (HbA1c) is 10% or lower * Participants have established atherosclerotic cardiovascular disease (ASCVD) and/or chronic kidney disease (CKD), as evidenced at least one of the following: * Coronary artery disease * Cerebrovascular disease * Peripheral arterial disease * Chronic kidney disease defined as: * eGFR \<45 millilitres/minute/1.73 meter squared (mL/min/1.73m\^2) and UACR \>30 milligram/gram (mg/g) (0.030 mg/mg) * eGFR \<60 mL/min/1.73 m\^2 and UACR \>100 mg/g (0.100 mg/mg), or * eGFR \<75 mL/min/1.73 m\^2 and UACR \>300 mg/g (0.300 mg/mg) (eGFR is calculated by central lab based on Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine-cystatin c equation as determined by central lab) * A Body Mass Index of ≥27.0 kilograms per meter squared (kg/m\^2)

Design outcomes

Primary

MeasureTime frameDescription
Time to First Occurrence of Composite EndpointsRandomization up to Study Completion (Approximate 248 Weeks)A composite endpoint includes nonfatal myocardial infarction (MI), nonfatal stroke, cardiovascular (CV) death, or hospitalization or urgent visit due to heart failure (HF).
Time to First Occurrence of Composite Endpoint of End Stage Kidney Disease (ESKD), ≥ 40% Sustained Decline in Estimated Glomerular Filtration Rate (eGFR), CV Death or Renal DeathRandomization up to Study Completion (Approximate 248 Weeks)ESKD is defined as the following individual components: persistent eGFR \<15 mL/min/1.73 m\^2 confirmed by 2 measurements at least 4 weeks apart at the central laboratory, initiation of dialysis for at least 28 days, receiving a kidney transplant. Sustained decline in eGFR (≥40%) will be confirmed by a repeated measure at least 4 weeks after the first result.
