Effects of AZD5004 in Adults Who Are Living With Obesity or Overweight With at Least 1 Weight-related Comorbidity (VISTA)

A Phase IIb Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy, Safety and Tolerability of AZD5004 in Participants Living With Obesity or Overweight With Comorbidity

A Phase IIb, global, randomized, parallel-group, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of AZD5004 compared with placebo, given once daily as an oral tablet(s) for 36 weeks, in male and female participants at least 18 years of age who are living with obesity (body mass index [BMI] ≥ 30 kg/m2), or overweight (BMI ≥ 27 kg/m2) who have at least 1 weight-related comorbidity

Study Overview

• Status: Completed
• Conditions: Obesity or Overweight
• Intervention / Treatment: Drug: AZD5004; Drug: Placebo

Detailed Description

This is a Phase IIb, global, randomized, parallel-group, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of 5 doses of AZD5004 compared with placebo, given once daily as an oral tablet or tablets for a duration of 36 weeks, in adults aged 18 years and above, who are living with obesity (BMI ≥ 30 kg/m2), or overweight (BMI ≥ 27 kg/m2) and have at least 1 weight-related comorbidity (Hypertension, Dyslipidemia or hyperlipidemia, CV disease and/or Obstructive sleep apnea). Approximately 304 participants will be randomized in the study. The dual primary endpoints are percent change in body weight from baseline at 26 weeks and the proportion of participants with weight loss ≥ 5% of baseline weight at 26 weeks.
