- Progression free survival (PFS) per RECIST 1.1 as assessed by BICR [ Time Frame: up to approximately 56 months ]To assess the efficacy in terms of PFS in all randomized patients and in patients with PD-L1 High tumors until disease progression
- Overall survival (OS) [ Time Frame: up to approximately 72 months ]To assess the efficacy in terms of OS in all randomized patients and in patients with PD-L1 High tumors until the date of death
- Adverse events (AEs) [ Time Frame: up to approximately 72 months ]To assess the safety and tolerability profile of durvalumab + dCRT compared to placebo + dCRT in patients with ESCC
