Pembrolizumab and Stereotactic Body Radiation Therapy in Treating Patients with Metastatic Melanoma or Non-small Cell Lung Cancer

Trial Status: closed to accrual

This phase Ib /IIa trial studies the side effects and best dose of stereotactic body radiation therapy when given together with pembrolizumab in treating patients with melanoma or non-small cell lung cancer that has spread to other places in the body. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Monoclonal antibodies, such as pembrolizumab, may block specific proteins which may strengthen the immune system and control tumor growth. Giving stereotactic body radiation therapy may prolong the response to pembrolizumab in patients with melanoma or non-small cell lung cancer.
