Study of Olatorepatide in Adult Participants Living With Overweight or Obesity Without Diabetes

June 29, 2026 updated by: Regeneron Pharmaceuticals

A Phase 2, Randomized, Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, and Efficacy of Olatorepatide, a GLP-1/GIP Receptor Agonist, With Different Doses and Drug-Titration Algorithms in Participants Living With Overweight or Obesity

This study will test an experimental drug called olatorepatide ("study drug") to determine how safe and effective this drug is compared to placebo and how easily the body can accept this drug at different doses and dosing schedules without causing side effects, as well as how the drug is processed in the body by participants with overweight or obesity but do not have diabetes.

The study is looking at:

  • What side effects the study drug might cause
  • How much study drug is in the blood at different times
  • How well the study drug works
  • What effects the study drug may have on the body at different dosing schedules
  • If the body makes antibodies to the study drug as this may cause the study drug to not work as well

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

All Individual Patient Data (IPD) that underlie publicly available results will be considered for sharing

IPD Sharing Time Frame

When Regeneron has:

  • received marketing authorization from major health authorities (e.g., FDA, European Medicines Agency (EMA), Pharmaceuticals and Medical Devices Agency (PMDA), etc.) for the product and indication or has globally discontinued development of the product for all indications on or after April 2020 and has no plans for future development
  • made the study results publicly available (e.g., scientific publication, scientific conference, clinical trial registry)
  • the legal authority to share the data, and
  • ensured the ability to protect participant privacy

IPD Sharing Access Criteria

Qualified researchers can submit a proposal for access to individual patient or aggregate level data from a Regeneron-sponsored clinical trial through Vivli. Regeneron's Independent Research Request Evaluation Criteria can be found at: https://www.regeneron.com/sites/default/files/Regeneron-External-Data-Sharing-Policy-and-Independent-Research-Request-Evaluation-Criteria.pdf
