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

Active Not RecruitingPhase 2, Phase 3

Sponsor: Vanderbilt University Medical Center

Conditions: Severe Obesity, Obesity, BMI Greater Than 30

Interventions: Tirzepatide, Standard of Care post-gastric bypass

Countries: United States

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). The investigators 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 continue with the current standard of care for patients who have previously undergone Gastric Bypass Surgery.
