Study of Durvalumab Versus Placebo in Combination With Definitive Chemoradiation Therapy in Patient With ESCC

Phase 3
Active, not recruiting
Conditions
Esophageal Squamous Cell Carcinoma
Interventions
Registration Number
NCT04550260
Lead Sponsor
AstraZeneca
Brief 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).

Detailed Description

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.
