A Phase I Study of Pembrolizumab Immunotherapy and Radiation Therapy in People with Inoperable Pleural Mesothelioma


Full Title

Phase I Dose Escalation and Local Control Study of Pembrolizumab + Intensity-Modulated Pleural Radiation Therapy (IMPRINT) for Malignant Pleural Mesothelioma


The purpose of this study is to learn if intensity-modulated pleural radiation therapy (IMPRINT) in combination with pembrolizumab immunotherapy is a safe treatment for people with malignant pleural mesothelioma, a cancer of the lining of the lungs. IMPRINT is a type of radiation therapy that specifically targets the lining of the lungs and the inner side of the ribs to stop cancer from growing. Pembrolizumab works by taking the brakes off the immune response, enhancing the ability of the immune system to find and kill cancer cells. It is given intravenously (by vein).

In this study, researchers will look for the highest dose of IMPRINT that can be given safely in combination with pembrolizumab. Once that dose is found, they will test it in combination with pembrolizumab in future participants to determine the effectiveness of the treatment.

Who Can Join

To be eligible for this study, patients must meet several criteria, including but not limited to the following:
