Frequently asked questions about LY4337713

What is LY4337713 used for?

LY4337713 is an investigational small molecule being studied for the treatment of ovarian neoplasms. It is also being evaluated in other FAP-positive solid tumors, including breast, pancreatic, colorectal, esophageal, stomach, and bile duct cancers. The drug is currently in Phase 1 clinical development.

What does LY4337713 target?

LY4337713 targets fibroblast activation protein (FAP), which is expressed in the tumor microenvironment of certain solid tumors. By targeting FAP, the drug aims to treat cancers that are positive for this protein, including ovarian neoplasms and other solid tumors listed in its clinical trial.

Who makes LY4337713?

LY4337713 is being developed by Eli Lilly and Company, a pharmaceutical company traded on the New York Stock Exchange under the ticker LLY. The drug is currently in Phase 1 clinical trials for the treatment of FAP-positive solid tumors.

What phase is LY4337713 in?

LY4337713 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still being studied in clinical trials to evaluate its safety and efficacy in patients with FAP-positive solid tumors.

What clinical trials is LY4337713 in?

LY4337713 is being studied in a Phase 1 clinical trial with the identifier NCT07213791. This trial is recruiting participants with FAP-positive solid tumors, including ovarian neoplasms, and is being conducted in the United States, China, Germany, Japan, and the Netherlands.
