Clinical trial

GLP-1 Receptor Agonists Post-Bariatric Surgery (GRABS) Feasibility Trial

Name
VR72411
Description
The goal of this pilot clinical trial is to determine the effectiveness of Tirzepatide in patients with persistent obesity (BMI \> 30) 12 months after bariatric surgery (Roux-en-Y Gastric Bypass). We also aim to determine the frequency of side effects with Tirzepatide in this patient population. Patients who take tirzepatide 12 months after bariatric surgery will be compared to patients who receive a placebo.
