Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with type 2 diabetes and BMI ≥27 kg/m2, with stable weight and a history of weight loss attempts.

Probably not a fit

Patients without type 2 diabetes, with very high liver enzyme levels, or non-diabetic overweight conditions may not benefit.

What this trial studies

This global, randomized, double-blind, parallel-group study compares AZD6234 with placebo in adults who have type 2 diabetes and body weight above 27 kg/m2. Participants will continue stable diabetes management and will be assigned to AZD6234 or placebo for 68 weeks to measure percent change in body weight from baseline. The trial also monitors safety and tolerability in a diverse, multicenter setting. Eligible participants include adults with type 2 diabetes for at least 90 days, a BMI of 27 or higher, and prior unsuccessful weight loss attempts. Enrollment is at sites in Alabama, with AstraZeneca as lead sponsor.

Why it matters

Potential benefit: If successful, AZD6234 could help some patients lose weight while managing diabetes.

How similar studies have gone: Previous lines of similar obesity-diabetes trials have shown weight loss benefits with comparable approaches; this trial builds on that framework.
