Anti-CTLA4-NF mAb (BMS986218), Nivolumab, and Stereotactic Body Radiation Therapy for the Treatment of Metastatic Solid Malignancies

This phase I/II trial studies the side effects of anti-CTLA4-NF monoclonal antibody (mAb) (BMS986218), nivolumab, and stereotactic body radiation therapy in treating patients with solid malignancies that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as anti-CTLA4-NF mAb (BMS-986218) and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving -CTLA4-NF mAb (BMS986218), nivolumab, and stereotactic body radiation therapy may kill more tumor cells.
