Radiation and immunotherapy join forces against mesothelioma
NCT ID NCT04926948
First seen Jun 27, 2026 · Last updated Jul 09, 2026 · Updated 2 times
Summary
This early-phase trial is testing whether combining a precise type of radiation (SBRT) with immunotherapy can safely treat pleural mesothelioma, a rare cancer of the lung lining. About 20 adults with confirmed mesothelioma will receive both treatments. The main goal is to see if the combination is feasible and does not cause too many severe side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- immunotherapy (immune checkpoint inhibitor) and stereotactic body radiation therapy (SBRT)
- What this could lead to
- If this works, it could point toward a more effective, less toxic treatment combination for mesothelioma.
- What could go wrong
- This is a very early phase 1 trial with only 20 participants, so it is primarily testing safety and feasibility, not effectiveness. The combination may cause unexpected side effects or fail to improve outcomes.
