Clinical Trial Summary

This randomized study evaluates the effect of subcutaneous semaglutide /in combination with lifestyle counseling in patients with type 2 diabetes mellitus (T2DM), overweight/obesity, and stage 4-5 chronic kidney disease (CKD) or dialysis-dependent end-stage kidney disease (ESKD) on patients' eligibility for kidney transplantation at the end of 9 months.

Description:

Transplant policies regarding listing consider uncontrolled diabetes and severe obesity to be contraindications though there is great variability for exact BMI (35-45 kg/m2) and A1c (9-10%) thresholds for listing by center. Glucagon-lowering peptide-1 receptor agonists (GLP-1 RAs) offer great promise in this population as they have been shown to reduce weight, central adiposity, A1c, and risk of cardiovascular outcomes with similar effects in patients with and without CKD.

In this double-blind, placebo-controlled randomized controlled trial, the investigators will evaluate the effect of subcutaneous semaglutide 1.34 mg/ml (up to 1.0 mg per week) in combination with lifestyle counseling in patients with T2DM, overweight/obesity, and stage 4-5 CKD or dialysis-dependent ESKD on patients' eligibility for kidney transplantation in terms of diabetes control (A1c <9%) and obesity (BMI <35 kg/m2 or 35-40 kg/m2 with waist circumference <120 cm) at the end of 9 months.

Intervention

Drug:
• Semaglutide 2 mg/1.5 ml (1.34 mg/ml), prefilled pen-injector for subcutaneous injection solution
Dose will be started at 0.25 mg per week. Dose escalation will occur every 4 weeks to mitigate risk of gastrointestinal side effects to a maximum dose of 1.0 mg per week.
• Placebo 1.5 ml, prefilled pen-injector for subcutaneous injection solution
Matched placebo solution for injection will be provided by Novo Nordisk in a 1.5 ml pre-filled pen-injector for subcutaneous injection with the same instructions on dose escalation.
