Frequently asked questions about Aleniglipron

What is Aleniglipron used for?

Aleniglipron is an investigational small molecule being developed for chronic weight management in adults with obesity or overweight, including those with weight-related comorbidities such as type 2 diabetes mellitus. It is being studied in clinical trials for conditions including obesity, overweight, and chronic weight management.

What does Aleniglipron target?

Aleniglipron targets the GLP-1 receptor. As a small molecule GLP-1 agonist, it is designed to activate the glucagon-like peptide-1 pathway, which plays a role in glucose metabolism and appetite regulation. This mechanism is being investigated for its potential in weight management and metabolic conditions.

Who makes Aleniglipron?

Aleniglipron is being developed by Structure Therapeutics Inc., a biopharmaceutical company listed on the stock exchange under the ticker symbol GPCR. The company is conducting clinical trials to evaluate the drug's efficacy and safety in adults with obesity or overweight and related metabolic conditions.

What phase is Aleniglipron in?

Aleniglipron is in Phase 2 clinical development. While some trials listed under its name are Phase 3, the drug's overall development stage is Phase 2, as it is still being evaluated for efficacy and safety in clinical studies. It is investigational and not yet approved by regulatory authorities.

What clinical trials is Aleniglipron in?

Aleniglipron is being studied in several clinical trials, including NCT07654374 (ACCOMPLISH-2) in adults with obesity or overweight and type 2 diabetes, NCT07654361 (ACCOMPLISH-1) in obesity or overweight with weight-related comorbidity, NCT07400588 in type 2 diabetes, and NCT06693843, a Phase 2b dose-ranging study in obesity or overweight.

Is Aleniglipron the same as GSBR-1290?

Yes, Aleniglipron is also known as GSBR-1290. The Phase 2b clinical trial NCT06693843 explicitly refers to Aleniglipron (GSBR-1290) in its title, confirming that these names refer to the same investigational drug being developed by Structure Therapeutics Inc.
