Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This study is testing a drug called patritumab deruxtecan in people with advanced gastrointestinal cancers that have spread. The drug is given through a vein and aims to shrink tumors. The trial will check how safe the drug is and how many people's cancers respond to treatment. About 180 adults with certain types of GI cancers are being recruited.

What this could mean

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

Active substance
patritumab deruxtecan (a targeted antibody-drug conjugate given by IV)
What this could lead to
If it works, this could offer a new treatment option for people with advanced gastrointestinal cancers that have not responded to other therapies.
What could go wrong
This is an early-phase trial (phase 1/2) with a small number of participants, so it is not yet known if the drug will be effective or safe in larger groups. Side effects are possible, and the cancer may still progress.

This is an AI summary of the original study and may miss details. Read our disclaimer.
