Summary

This is a Phase III, randomized, double-blind, placebo-controlled, multi-center international
study to assess the efficacy and safety of durvalumab administered concurrently with dCRT in
patients with locally advanced, unresectable esophageal squamous cell carcinoma (ESCC).

Objectives

Approximately 600 patients with locally advanced, unresectable ESCC (AJCC 8th cStage II-IVA)
will be randomized in a 2:1 ratio to receive either durvalumab + dCRT or placebo + dCRT. The
primary objectives of this study are to assess the efficacy of durvalumab + dCRT compared
with placebo + dCRT in terms of progression free survival (PFS, per RECIST 1.1 as assessed by
BICR) in PD-L1 High population.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts... Click here to learn more about clinical trials.
