Can a Two-Drug combo tip the scales against obesity?
NCT ID NCT07765511
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This early-stage trial is testing whether a new drug called macupatide, given alone or with another drug called eloralintide, is safe and well-tolerated in Japanese adults with obesity or overweight who do not have type 2 diabetes. Participants will receive multiple doses and stay at a research unit for monitoring. The study also looks at how the drugs move through the body and whether they affect body weight.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Macupatide (alone and in combination with eloralintide), given as injections
- What this could lead to
- If successful, this could support the development of a new combination treatment for obesity, potentially offering better weight loss options.
- What could go wrong
- This is an early-phase trial focused on safety and dosing, not proof of effectiveness. Side effects are possible, and the results may not lead to a marketable treatment.
