Details and patient eligibility

About

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.

Enrollment: 10,000 estimated patients

Sex: All

Ages: 45+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• A Body Mass Index of ≥27.0 kilograms per meter squared (kg/m^2)

• Participants may be with or without type 2 diabetes (T2D) unless 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)
    • eGFR <60 mL/min/1.73 m^2 and UACR >100 mg/g, or
    • eGFR <75 mL/min/1.73 m^2 and UACR >300 mg/g (eGFR is calculated based on Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) cystatin c equation as determined by central lab)
