Obesity or Overweight

Keywords

Obesity, Overweight, AZD6234

Brief summary

The study will evaluate how well AZD6234 works and how safe it is in adults with excess weight or obesity. Efficacy of AZD6234 will be compared to placebo in percent body weight change from baseline at 68 weeks of treatment

Detailed description

This is a Phase III, global, randomised, parallel-group, double-blind, multicentre study to assess the efficacy and safety of AZD6234 compared with placebo, administered SC once weekly in adults with obesity or overweight with at least one weight-related comorbidity without T2DM. Eligible participants will be randomized to either receive AZD6234 or matching placebo respectively.

Interventions

IMP injected subcutaneously, once a week. Unit dose strength as per CSP.

DRUGPlacebo

Placebo matching IMP dose injected subcutaneously, once a week.
