Randomized Double Blinded Placebo-Controlled w/Semaglutide to Prevent Weight Gain After Liver Transplant

Official title

A Randomized Double Blinded Placebo-Controlled Trial of Semaglutide to Prevent Weight Gain Following Liver Transplantation

Overview

In this study, semaglutide will be compared to placebo (a look-alike inactive substance, a "sugar pill") to determine if its use will prevent weight gain after liver transplantation (LT). In addition, researchers will be testing to determine if semaglutide prevents the development of Non-Alcoholic Fatty Liver Disease (NAFLD) after transplant through Magnetic Resonance Imaging (MRI) and laboratory results.

Detailed description

Weight gain following LT is common and a risk for cardiovascular disease and development of NAFLD. Developing NAFLD following LT can lead to patients developing scar tissue in the graft (transplanted liver), and graft-cirrhosis. These events can limit the benefit of the transplanted liver graft and reduce the benefit of LT as a therapy. Current weight management strategies have not been successful at the prevention of these events in most patients. This highlights a substantial unmet need for effective treatment to prevent or reduce post-LT weight gain and highlight the importance of new treatment strategies for reducing illness, death, and healthcare cost associated with post-LT weight gain.

The purpose of this research study is to test the safety, tolerability, and effectiveness of semaglutide when used to prevent weight gain after liver transplant. Semaglutide is a drug that has been approved by the U. S. Food and Drug Administration (FDA) for treatment of obesity and Type 2 Diabetes.

Semaglutide, has shown to be effective for not only weight loss but also long-term weight maintenance. Semaglutide has also shown to be helpful in treatment of nonalcoholic steatohepatitis (NASH) in the non-transplant population. This medication also is used to control blood sugar and prevent cardiovascular disease, which contributes to poor outcomes in LT recipients. Thus, the purpose of the present study is to determine if use of semaglutide early after LT can (1) reduce weight gain and (2) prevent development of NAFLD following LT.

Interventions

• Drug Semaglutide Pen Injector
  Starting dose of 0.24 mg injected weekly and increased every 4 weeks to a potential maximum dose of 2.4 mg weekly at 20 weeks followed by 52 weeks of weekly injections at the maximum tolerable dose
• Drug Placebo
  Placebo solution injected weekly for 72 weeks

Primary outcome measures

• Change in weight [Time frame: Baseline to week 72]

Secondary outcome measures (7)

• Development of NAFLD [Time frame: Week 72]
• Change in adiposity [Time frame: Baseline to week 72]
• Change in insulin resistance [Time frame: Baseline to week 72]
• Change in inflammation - C-reactive protein (CRP) [Time frame: Baseline to week 72]
• Change in inflammation - adiponectin [Time frame: Baseline to week 72]
• Change in liver fibrosis markers [Time frame: Baseline to week 72]
• Change in serum lipid profile [Time frame: Baseline to week 72]
