Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 and older with BMI ≥30, or BMI ≥27 with a weight-related comorbidity, and who have not had recent diabetes.
✕Probably not a fit
People with diabetes, significant liver disease, or certain metabolic conditions may not benefit and may be ineligible.

What this trial studies
This global, randomized, double-blind study compares AZD6234 given as a once-weekly subcutaneous shot to placebo in adults with obesity or overweight and at least one weight-related health condition, over 68 weeks. Participants will be assigned to AZD6234 or placebo and monitored for weight change and safety. The trial excludes people with diabetes and certain liver or endocrine conditions to better understand the drug’s effects in the target population. Primary outcomes focus on percent body weight change from baseline at 68 weeks, with ongoing safety assessments. Sites include research centers in Alabama and Arizona.
Why it matters
Potential benefit: If successful, AZD6234 could help participants achieve meaningful weight loss and improve related health conditions.
How similar studies have gone: Previous studies with similar weight-management approaches have shown potential weight loss benefits in comparable populations, but this study is in a new treatment class.
