Frequently asked questions about LY3841136

What is LY3841136 used for?

LY3841136 is an investigational small molecule being studied for weight management in obesity and overweight, including in people with type 2 diabetes. It is also being evaluated in clinical trials for hepatic insufficiency and kidney disease. The drug is in clinical development and is not approved by the FDA.

What does LY3841136 target?

LY3841136 targets the amylin receptor, a receptor class involved in regulating appetite and food intake. By acting on this receptor, the drug is being studied for its potential to support weight management in people with obesity or overweight. It is a small molecule developed by Eli Lilly and Company.

Who makes LY3841136?

LY3841136 is being developed by Eli Lilly and Company, a pharmaceutical company listed on the stock exchange under the ticker LLY. The drug is an investigational small molecule in clinical development for obesity and related metabolic conditions. It is not yet approved for any use.

What phase is LY3841136 in?

LY3841136 is in Phase 1 and Phase 2 clinical trials. Most completed studies are Phase 1, and an active Phase 2 trial is investigating the drug alone or with tirzepatide for weight management in adults with obesity or overweight and type 2 diabetes. The drug remains investigational.

What clinical trials is LY3841136 in?

LY3841136 has three clinical trials. NCT05295940 and NCT06297616 are completed Phase 1 studies in healthy, overweight, or obese participants. NCT06603571 is an active Phase 2 trial testing the drug with tirzepatide in obesity or overweight with type 2 diabetes. NCT07401862 is a recruiting Phase 1 study in hepatic insufficiency.

Is LY3841136 the same as eloralintide?

Yes, LY3841136 is also known as eloralintide. A clinical trial titled 'A Study of Eloralintide (LY3841136) in Participants With Different Levels of Liver Damage' confirms that eloralintide is another name for this drug. Both names refer to the same investigational small molecule developed by Eli Lilly.
