NCT ID NCT07301437
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether taking liraglutide together with orlistat helps overweight or obese adults lose more weight than liraglutide alone. About 120 participants will be followed for 24 weeks. The goal is to see which approach works better in real-world conditions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- liraglutide and orlistat
- What this could lead to
- If successful, this could show that combining liraglutide with orlistat leads to greater weight loss than liraglutide alone, offering a more effective option for managing obesity.
- What could go wrong
- This is a real-world study, not a tightly controlled trial, so results may be less reliable. Side effects from either drug could limit use, and weight loss may vary widely among participants.
