Weight-loss surgery plus GLP-1 medication for severe obesity
Official title: The Efficacy and Safety of Bariatric Surgery Combined With GLP-1 Receptor Agonists for Patients With Severe Obesity: A Prospective, Multicenter Cohort Study
Run by China-Japan Friendship Hospital · NCT07336862 · Data updated 2026-11-12
This trial will test whether adding a GLP‑1 receptor agonist medicine to sleeve gastrectomy helps adults with BMI ≥35 and metabolic conditions keep off weight and improve metabolic health.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–60 years old with BMI ≥35 kg/m² who are primary candidates for laparoscopic sleeve gastrectomy and have metabolic syndrome or type 2 diabetes and have not used GLP‑1 RAs in the prior 6 months.
✕Probably not a fit
Patients with advanced hepatic or renal failure, active malignancy, prior bariatric surgery, recent GLP‑1RA treatment, or those requiring reoperation for severe postoperative complications are unlikely to benefit from this protocol.

What this trial studies
This phase 1/2 interventional trial compares laparoscopic sleeve gastrectomy alone to sleeve gastrectomy plus adjuvant GLP‑1 receptor agonist therapy in adults with severe obesity and metabolic comorbidities. Eligible participants are primary LSG candidates aged 18–60 with BMI ≥35 kg/m² and metabolic syndrome or type 2 diabetes, and they are assigned to either the BS‑GLP group or the BS group. Investigators will follow weight, glycemic and lipid markers, and safety outcomes over time to measure durability of weight loss and metabolic improvement. Key exclusions include prior bariatric surgery, recent GLP‑1RA use, advanced organ dysfunction, active malignancy, and autoimmune disease requiring immunosuppression to protect safety and reduce confounding.
Why it matters
Potential benefit: If successful, combining surgery with GLP‑1 therapy could produce greater and more durable weight loss and better metabolic control than surgery alone.
How similar studies have gone: Bariatric surgery and GLP‑1 receptor agonists have each shown substantial weight-loss and metabolic benefits on their own, but large randomized long-term trials testing their combined use are still limited.
