New weekly shot shows promise for weight loss and diabetes
NCT ID NCT06628362
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new weekly injection called enicepatide (CT-388) in 447 overweight or obese adults with type 2 diabetes. Participants receive either the drug or a placebo for 48 weeks. The goal is to see if the drug helps with weight loss and improves blood sugar levels.

- Enicepatide (CT-388)
- What this could lead to
- If successful, this could lead to a new once-weekly injection that helps people with type 2 diabetes lose weight and better control their blood sugar.
- What could go wrong
- This is an early-phase trial with only 447 participants, so results may not apply to everyone. Side effects and lack of long-term data are common risks at this stage.
