Summary
This completed Phase 2 study tested different doses of CX11 tablets against a placebo in 250 overweight or obese adults. Participants took the pill once daily with meals for 36 weeks, followed by a 2-week safety check. The main goal was to see how much weight people lost and whether the drug was safe and tolerable.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CX11 (also known as VCT220) tablets
- What this could lead to
- If successful, this could lead to a new daily pill to help people with obesity lose weight and improve related health issues like high blood pressure or prediabetes.
- What could go wrong
- This is an early Phase 2 trial with only 250 people, so results may not apply to everyone. The drug may cause side effects or fail to show meaningful weight loss compared to placebo.
