Durvalumab, Tremelimumab and Hypofractionated Radiation Therapy in Treating Patients With Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma

This phase I/II trial studies the side effects of durvalumab, tremelimumab and hypofractionated radiation therapy in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving durvalumab, tremelimumab, and hypofractionated radiation therapy may work better in treating patients with recurrent or metastatic head and neck squamous cell carcinoma.
