The purpose of this study is to compare the effect of adding nivolumab to the usual chemotherapy (cisplatin or carboplatin with gemcitabine) versus the usual chemotherapy alone in treating patients with nasopharyngeal cancer that has come back (recurrent) or spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, carboplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab with the usual chemotherapy may work better than the usual chemotherapy alone in treating patients with nasopharyngeal cancer.
