A Pilot Study of Durvalumab (MEDI4736) with Tremelimumab in Combination with Image-Guided Stereotactic Body Radiotherapy in the Treatment of Metastatic Anaplastic Thyroid Cancer.

ABSTRACT: Background: Metastatic anaplastic thyroid cancer (ATC) has a poor prognosis. This pilot study aims to evaluate tremelimumab plus durvalumab with stereotactic body radiotherapy (SBRT) to improve overall survival (OS). Methods: Eligible patients received up to 4 doses tremelimumab (75 mg) given q4 weeks and up to 1 year of durvalumab (1500 mg) given q4 weeks. SBRT at 9 Gy × 3 fractions was given within the first 2 weeks of the start of treatment. Paired biopsies (pretreatment and between 3 and 10 weeks after the first dose of the drug treatment) were done in the medically qualified patients. Major inclusion criteria are metastatic ATC, Eastern Cooperative Oncology Group (ECOG) performance status 0-2, no prior immunotherapy, and last anticancer treatment >7 days be
