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.
Interventions
Durvalumab intravenous infusion
Durvalumab matching placebo for intravenous infusion
cisplatin + fluorouracil, as per Standard of Care
cisplatin + capecitabine, as per Standard of Care
50-64Gy in total

Exclusion criteria
* Histologically or cytologically confirmed small cell esophageal carcinoma, esophageal adenocarcinoma or other mixed carcinoma. * Prior anti-cancer treatment for ESCC. * Patient with a great risk of perforation and massive bleeding. * History of allogeneic organ transplantation. * Active or prior documented autoimmune or inflammatory disorders. * Uncontrolled intercurrent illness. * History of another primary malignancy. * Active infection including tuberculosis, hepatitis B, hepatitis C, or human immunodeficiency virus. * Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
