This phase Ib/II trial studies the side effects of durvalumab when given together with chemotherapy and radiation therapy in treating patients with esophageal or gastroesophageal junction cancer. Both durvalumab and tremelimumab are antibodies (proteins) which bind to cells involved in the immune system. Antibodies are normally made by the body to destroy germs, like bacteria and viruses. The antibodies in this study are designed to boost the body’s immune system, by allowing immune cells to be more active and fight the cancer. Durvalumab works by interacting with an immune molecule called PD-L1, located on the tumor cells and white blood cells. Tremelimumab works by interacting with an immune molecule called CTLA-4, located on white blood cells. Both durvalumab and tremelimumab may help strengthen the immune system. Drugs used in chemotherapy, such as fluorouracil, leucovorin calcium, oxaliplatin, carboplatin and paclitaxel, 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. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving durvalumab together with chemotherapy and radiation therapy before surgery may work better at treating patients with esophageal or gastroesophageal junction cancer.

PRIMARY OBJECTIVE:
I. Assess the pathologic complete response rate of durvalumab/tremelimumab with positron emission tomography (PET)-directed chemotherapy and radiation followed by surgery.
SECONDARY OBJECTIVES:
I. Assess the safety of durvalumab/tremelimumab with PET-directed chemotherapy and radiation followed by surgery.
II. Determine the progression-free (PFS) and overall survival (OS) of durvalumab/tremelimumab with PET-directed chemotherapy and radiation followed by surgery and adjuvant durvalumab/tremelimumab for patients with completely resected disease.
EXPLORATORY OBJECTIVE:
I. Correlate outcomes - pathologic complete response (pCR), PFS and OS - with immune correlative assays and Memorial Sloan Kettering (MSK)-Integrated Mutation Profiling of Actionable Cancer Targets (IMPACT) profiles.
OUTLINE:
INDUCTION CHEMOTHERAPY: Patients receive fluorouracil intravenously (IV) over 46-48 hours, oxaliplatin IV over up to 6 hours and leucovorin calcium IV over 2 hours. Treatment repeats every 14 days for 2 cycles in the absence of disease progression or unacceptable toxicity.
Beginning 2 weeks after second cycle of induction chemotherapy, patients receive durvalumab IV over 60 minutes and tremelimumab IV over 1 hour on day 29 before and during the third week of chemoradiation. Patients undergo external beam radiation therapy (EBRT) 5 days per week on Monday-Friday for 23 fractions over 5.5 weeks starting >= 14 days after durvalumab in the absence of disease progression or unacceptable toxicity. PET responders receive oxaliplatin IV over up to 6 hours and fluorouracil IV over 96 hours once every 2 weeks for up to 3 doses or capecitabine orally (PO) twice daily (BID) on Monday-Friday with radiation. PET non-responders receive carboplatin IV over 30 minutes and paclitaxel IV over 60 minutes once per week for 5 weeks concurrent with radiation. Beginning 6-10 weeks following chemoradiation therapy, patients undergo esophagectomy. Beginning approximately 6-12 weeks following surgery, patients who have had complete removal of the tumor receive durvalumab IV over 60 minutes and tremelimumab IV over 1 hour on day 1. Treatment repeats every 4 weeks for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo an endoscopy with biopsy at baseline and blood sample collection, and computed tomography (CT), PET/CT, or magnetic resonance imaging (MRI) throughout the study.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
