Once-a-Month obesity shot put to the test
NCT ID NCT07842640
First seen Sep 25, 2026 · Last updated Sep 25, 2026
Summary
Researchers are testing an experimental injection called ASC35 in adults with obesity or overweight. The trial gives single and increasing doses to see how safe the drug is, how well people tolerate it, and how the body processes it. Some participants receive ASC35, some receive a placebo, and others receive tirzepatide, a weekly weight-loss drug, for comparison. The study also tracks changes in 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
- ASC35, an experimental once-monthly injection for weight management
- What this could lead to
- If it works, this could point toward a weight-management injection people take once a month instead of once a week.
- What could go wrong
- This is a small, early-stage safety trial, so it cannot show whether ASC35 helps people lose weight. Many drugs at this stage fail or cause side effects that stop further testing.
