Summary

This study tested an experimental drug called ozuriftamab vedotin in 42 people with head and neck cancer that returned or spread. The goal was to see if the drug could shrink tumors and to check for side effects. Participants received the drug alone or with other treatments, and researchers measured how many responded and how long the benefit lasted.
