Three blockbuster Weight-Loss drugs go Head-to-Head in diabetic and Non-Diabetic adults
NCT ID NCT07820111
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers compare three weekly GLP-1 receptor agonists, dulaglutide, semaglutide, and tirzepatide, in 159 obese adults, 84 with diabetes and 75 without. Participants receive one of the drugs for 24 weeks. The trial measures changes in body weight, BMI, blood sugar, cholesterol, and liver enzymes at 3 and 6 months to see how the drugs differ between diabetic and non-diabetic people.
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 injections: dulaglutide, semaglutide, or tirzepatide
- What this could lead to
- If one drug works better for a specific group, doctors could tailor obesity and diabetes treatment more precisely. The results may also clarify how these drugs affect cholesterol and liver enzymes, not just weight.
- What could go wrong
- This is a single-center study of 159 people over 24 weeks, so differences between drugs may be small or fade with longer use. GLP-1 drugs commonly cause nausea, vomiting, and diarrhea, and some participants may stop treatment early.
