Summary

This study tested an experimental drug called cofetuzumab pelidotin for people with a specific type of advanced lung cancer (non-small cell lung cancer) that had returned after other treatments. The drug was designed to target a protein called PTK7 found on cancer cells. The study was stopped early, and results are limited. It involved 65 participants.
