Lung cancer trial adding radiation to immunotherapy halted early
NCT ID NCT05223647
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding radiation to the chest could improve survival for people with extensive-stage small-cell lung cancer who were already receiving chemotherapy and immunotherapy. The trial planned to enroll 239 participants but was terminated early. The main goal was to see if the combination increased the number of people alive after one year.
