Iodine I-131, Recombinant Thyrotropin Alfa, and Durvalumab in Treating Patients with Recurrent or Metastatic Thyroid Cancer

Trial Status: closed to accrual

This pilot early phase I trial studies the side effects of iodine I-131, recombinant thyrotropin alfa, and durvalumab in treating patients with thyroid cancer that has come back after a period of improvement or that has spread to other parts of the body. Iodine I-131 is a radioactive form of iodine used to kill tumor cells and shrink tumors. Recombinant thyrotropin alfa may maximize the amount of iodine I-131 taken up by tumor cells. Monoclonal antibodies, such as durvalumab, may block tumor growth in different ways by targeting certain cells. Giving iodine I-131, recombinant thyrotropin alfa, and durvalumab may work better in treating patients with thyroid cancer.
