RICE: Radio-Immuno-Chemotherapy of Cancer of the Esophagus
A phase II trial to evaluate safety and efficacy of adding durvalumab (MEDI4736) to standard neoadjuvant radiochemotherapy and of adjuvant durvalumab +/- tremelimumab in locally advanced esophageal adenocarcinoma and to evaluate biomarkers predictive for response to immune checkpoint inhibition
|Condition or Disease
Short Study Title: RICE - Radio-Immuno-Chemotherapy of Cancer of the Esophagus
Study Phase: Phase II
Research hypothesis: The investigators aim at evaluating if (I) esophageal cancer is susceptible to immunotherapeutic approaches based on interference with the PD1 / PDL1 axis, if (II) treatment of locally advanced tumors by immunotherapeutic approaches increases cure rate and if (III) combination with radiotherapy is feasible and increases anti-tumor immunity.
Primary Objectives: The primary objective is to evaluate safety and efficacy (measured by an increase of pathological complete response rate from 20% to 35%) of the fully human monoclonal IgG1 antibody durvalumab targeting the programmed death-ligand 1 (PD-L1) in combination with neoadjuvant radiochemotherapy, followed by surgery for locally advanced esophageal cancer and cancer of the gastric esophageal junction (GEJ).
Arms and Interventions
Treatment arm A will receive durvalumab IV in a dosage of 1500mg every four weeks for 12 months as mono therapy.
Drug: Durvalumab 50 MG/ML
|Experimental: Durvalumab + Tremelimumab
Treatment arm B receives durvalumab in a dosage of 1500mg every 4 weeks (-3/+7 days) for 12 months post-surgery. In addition these patients receive tremelimumab IV in a fixed dose of 75mg for the first four months on day 1; 29; 57; 85 (-3/+7).
Drug: Durvalumab 50 MG/ML
IV Infusion, Combination with Durvalumab

Reproductive Status Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception and must agree to use adequate method to avoid pregnancy for 5 months (30 days plus the time required for durvalumab to undergo five half-lives) after the last dose of study drug.
Appropriate methods of contraception are:
