Clinical trial Recruiting at 56 sites Phase 3 Interventional Ages 18 and up

AZD6234 added to current diabetes therapy to help with weight loss in adults who are overweight or have obesity

Official title: A Phase III Randomised, Double-Blind, Placebo-Controlled Multicentre Trial to Evaluate the Efficacy and Safety of AZD6234 as an Adjunct to Incretin-based Therapies in Participants With Obesity or Overweight With at Least One Weight-Related Comorbidity With or Without Type 2 Diabetes Mellitus (SELENE 3)

Run by AstraZeneca · NCT07776509 · Data updated 2026-11-12

This study tests whether AZD6234, when added to a person’s current incretin-based weight management therapy, can help adults with obesity or overweight lose more weight than a placebo over about 68 weeks.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 years or older with obesity or overweight plus a weight-related comorbidity, who are on stable incretin-based therapy and meet specific BMI or comorbidity criteria (with or without type 2 diabetes).

Probably not a fit

Individuals not achieving weight loss or experiencing adverse effects may not benefit from AZD6234 addition and could discontinue due to intolerance or lack of efficacy.

What this trial studies

This is a Phase 3, global, randomized, parallel-group, double-blind trial evaluating the safety and efficacy of AZD6234 as an add-on to ongoing incretin-based therapies in adults with obesity or overweight and at least one weight-related comorbidity, with or without type 2 diabetes. Participants will be randomly assigned to receive AZD6234 or a matching placebo while continuing their background incretin-based treatment. The primary endpoint is percent body weight change from baseline at 68 weeks. The study will be conducted across multiple centers with stable background therapy and predefined inclusion criteria to ensure enrolled individuals have significant weight-related health risks. Lead sponsor is AstraZeneca.

Why it matters

Potential benefit: If successful, participants may experience greater weight loss and improved weight-related health risks when adding AZD6234 to their current therapy.

How similar studies have gone: Previous studies in this class/platform have shown promise with adjunct therapies for weight management, though results can vary by population and background therapy.
