Frequently asked questions about Aleniglipron

What is Aleniglipron?

Aleniglipron is an investigational small molecule developed by Structure Therapeutics Inc. for obesity, overweight, chronic weight management, and related metabolic conditions. It is being studied in adults with obesity or overweight, including people with type 2 diabetes and weight-related comorbidities, and in a separate study in people with hepatic impairment.

What does Aleniglipron target?

Aleniglipron targets GLP-1, the glucagon-like peptide-1 receptor. It is a small molecule designed to act on this incretin pathway, which is the same target class engaged by GLP-1 receptor agonist therapies used in weight management and diabetes care.

Who makes Aleniglipron?

Aleniglipron is developed by Structure Therapeutics Inc., a company whose shares trade under the ticker GPCR. Structure Therapeutics is the sponsor of the clinical program studying aleniglipron in obesity, overweight, type 2 diabetes, and hepatic impairment.

What phase is Aleniglipron in?

Aleniglipron is in clinical development and is not approved for any use. Its program spans Phase 1, Phase 2, and Phase 3 studies: a completed Phase 2 trial in type 2 diabetes, two recruiting Phase 3 ACCOMPLISH trials, and a Phase 1 hepatic impairment study that has not yet begun recruiting.

What clinical trials is Aleniglipron in?

Aleniglipron trials include ACCOMPLISH-1 (NCT07654361), a recruiting Phase 3 study of 3,600 participants with obesity or overweight plus a weight-related comorbidity, and ACCOMPLISH-2 (NCT07654374), a recruiting Phase 3 study of 1,100 adults with obesity or overweight and type 2 diabetes. A completed Phase 2 trial is NCT07400588, and NCT07872033 is a Phase 1 hepatic impairment study.

What is Aleniglipron used for in obesity?

Aleniglipron is being studied for obesity, overweight, and chronic weight management in adults. The Phase 3 ACCOMPLISH-1 trial enrolls participants with obesity or overweight and a weight-related comorbidity, while ACCOMPLISH-2 enrolls adults with obesity or overweight who also have type 2 diabetes.
