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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
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.
