- Conditions
- Obesity or Overweight
- Interventions
- Registration Number
- NCT06862791
- Lead Sponsor
- AstraZeneca
- Brief Summary
The purpose of this study is to determine whether treatment with AZD9550 when given in combination with AZD6234 as once weekly subcutaneous (SC) injections is superior to placebo or either agent administered as monotherapy for weight loss in participants living with obesity or overweight with at least one weight-related co-morbidity.
- Detailed Description
This is a Phase IIb, global, randomised, parallel-group, double-blind, placebo-controlled, multi-centre, reduced factorial study designed to evaluate the efficacy, safety and tolerability of treatment with AZD9550 and AZD6234 in combination or as monotherapy in adults who are living with obesity or overweight with at least one of the following weight-related co-morbidities: hypertension, dyslipidemia or obstructive sleep apnoea. The study is composed of a screening period, a treatment period and a follow up period with participants expected to be in the study for approximately 47 weeks. The study will be conducted at around 60 sites and in approximately 7 countries with about, 360 participants will be randomly assigned to study intervention or placebo.
