NCT ID NCT07834398
First seen Sep 22, 2026 ยท Last updated Sep 22, 2026
Summary
Researchers compare three weekly GLP-1 receptor agonist drugs, dulaglutide, semaglutide, and tirzepatide, in 150 obese adults without diabetes. Participants receive one of the drugs for six months. The trial measures changes in body weight, BMI, blood sugar, cholesterol, and liver function to see which drug works best.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- weekly GLP-1 receptor agonist drugs: dulaglutide, semaglutide, and tirzepatide
- What this could lead to
- If one drug helps more, doctors could choose the most effective weekly option for weight loss in people with obesity who do not have diabetes.
- What could go wrong
- This is a six-month study of 150 people, so it cannot show long-term weight maintenance or rare side effects. GLP-1 drugs commonly cause nausea and digestive issues, and results may not apply to everyone.
