Frequently asked questions about LY3457263

What is LY3457263?

LY3457263 is an investigational small molecule being developed by Eli Lilly and Company for metabolic conditions, including type 2 diabetes and overweight. It is designed to act on the GLP-1 receptor and is given as an oral therapy. The drug remains in clinical development and is not approved for any indication.

What is LY3457263 used for in type 2 diabetes?

LY3457263 is being studied for the treatment of type 2 diabetes, including in patients already taking stable doses of semaglutide or tirzepatide. It is also being evaluated in people who are overweight or obese. All of these uses are investigational and have not been approved by regulators.

What does LY3457263 target?

LY3457263 targets the GLP-1 receptor, the same receptor class engaged by approved GLP-1 based therapies. By acting on this receptor, the small molecule is intended to influence glucose control and body weight. It is an oral small molecule rather than a peptide injection.

Who is developing LY3457263?

LY3457263 is being developed by Eli Lilly and Company, which trades on the New York Stock Exchange under the ticker LLY. Lilly is running the clinical program for the asset across type 2 diabetes and overweight or obesity indications.

What phase is LY3457263 in?

LY3457263 is in Phase 1 development overall, with a Phase 2 study now recruiting. The Phase 1 program includes completed studies in healthy participants, participants with type 2 diabetes, and participants with obesity. The drug is investigational and has not been approved for any use.

What clinical trials is LY3457263 in?

The active study is NCT06897475, a Phase 2 trial of LY3457263 versus placebo in participants with type 2 diabetes on stable semaglutide or tirzepatide, enrolling about 200 people across the United States, Canada, Germany, Poland, Puerto Rico, and the United Kingdom. Completed Phase 1 trials include NCT05582096, NCT05377333, and NCT04641312.
