What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

LY4337713 (a radioligand therapy given intravenously)

What this could lead to

If it works, this could point toward a new treatment option for several hard-to-treat cancers that have a specific protein called FAP.

What could go wrong

This is a very early Phase 1 trial, so the main goals are safety and dosing—not yet proving it works. The drug may cause side effects or fail to shrink tumors.

Conditions

The condition(s) this trial relates to.

breast neoplasm cholangiocarcinoma colorectal neoplasm Esophageal Neoplasms gastric neoplasm ovarian cancer Pancreatic Intraductal Neoplasms
