EloraTZP for weight loss in adults with overweight/obesity and type 2 diabetes

Official title: A Phase 3 Study to Investigate the Efficacy and Safety of LY900043 in Adult Participants With Obesity or Overweight and Type 2 Diabetes

Run by Eli Lilly and Company · NCT07881458 · Data updated 2026-11-12

This trial tests whether a coformulation of eloralintide and tirzepatide helps people with obesity or overweight and type 2 diabetes lose weight compared with tirzepatide alone.

Is this trial a fit for you?

Likely a good fit

Adults with type 2 diabetes, BMI ≥27 kg/m2, stable weight for 90 days, and a history of unsuccessful prior weight-loss efforts.

Probably not a fit

Individuals with type 1 diabetes, recent obesity-related procedures, or recent use of certain boxed medications or insulin may not benefit from this therapy.

What this trial studies

This phase 3 interventional study compares the weight-reduction effects and safety of the eloralintide-tirzepatide coformulation (EloraTZP) to tirzepatide in adults with obesity or overweight and type 2 diabetes. Participants are adults with BMI ≥27 kg/m2 who have had limited weight loss despite prior efforts, and who meet specific medical criteria. The study lasts about two years and excludes individuals with certain prior obesity procedures, specific competing medications, or type 1 diabetes. Outcomes focus on body weight changes and safety signals related to the combination therapy. Conducted at sites in Arizona and California under Eli Lilly and partnering centers.

Why it matters

Potential benefit: If successful, EloraTZP could provide greater weight loss and improved metabolic health for adults with obesity or overweight and type 2 diabetes.

How similar studies have gone: Prior studies with GLP-1/GIP-based therapies and similar agents have shown promise for weight loss, but the specific EloraTZP coformulation represents a novel combination approach.
