| Source and design | What it supports | What it cannot establish |
|---|---|---|
| Aronne et al., 2025: SURMOUNT-5 Randomized open-label comparison in adults with obesity without diabetes; 72 weeks | Tirzepatide produced greater average weight reduction than semaglutide in this study. | Open-label design; findings are specific to the tested regimens and study population. |
What did the head-to-head trial find?
In adults with obesity without diabetes, tirzepatide produced greater average weight reduction at 72 weeks under the study conditions. The trial compared particular regimens; it was not a test of every possible product or treatment plan.
Why trial design matters
Random assignment strengthens the comparison, while the open-label design means treatment assignment was known. Read the trial’s methods, adverse events and treatment discontinuations alongside the headline result.
How should I use this information?
Average outcomes do not determine the right medicine for an individual. Use the current prescribing information and discuss relevant benefits, harms, medical history and monitoring with a licensed clinician. The individual guides link to additional trial and product-quality context.
Common questions
Does this mean everyone should choose tirzepatide?
No. A group-level trial result does not replace individual clinical assessment or the instructions for a specific prescribed product.
