This phase I trial studies the side effects and best dose of birinapant when given together with intensity modulated re-irradiation therapy (IMRRT) in treating patients with head and neck squamous cell carcinoma that has come back at or near the same place as the original (primary) tumor (locally recurrent). Birinapant may stop the growth of tumor cells by blocking inhibitor of apoptosis (IAP), a protein needed for tumor cell survival. IMRRT uses thin beams of radiation of different intensities that are aimed at the tumor from many angles. This type of re-irradiation therapy reduces the damage to healthy tissue near the tumor. Giving birinapant with IMRRT may lower the chance of head and neck squamous cell carcinoma growing or spreading.
