Summary

This study tests a new drug called IMC-R117C, alone or with other cancer drugs, in people with advanced colorectal, esophageal, stomach, or ovarian cancers that have a specific genetic marker (HLA-A*02:01) and produce a protein called PIWIL1. The trial aims to find safe doses and check if the drug can shrink tumors. About 600 participants will be enrolled.

What this could mean

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

Active substance
IMC-R117C (a bispecific protein that targets cancer cells and immune cells)
What this could lead to
If successful, this could lead to a new treatment option for certain advanced cancers that have not responded to standard therapies.
What could go wrong
This is an early first-in-human trial, so safety and effectiveness are not yet known. The drug may cause side effects or fail to shrink tumors.
