A Study of Chemoradiation in Combination with Tislelizumab As First Line Treatment in Participants with Advanced Esophageal Squamous Cell Carcinoma
- Conditions
- Esophageal Squamous Cell Carcinoma
- Interventions
- Radiation: Intensity-modulated radiotherapy (IMRT)
- Registration Number
- NCT05919030
- Lead Sponsor
- Renmin Hospital of Wuhan University
- Brief Summary
This study is a multicentre, randomised, parallel-controlled, open-label, 3 phase clinical trial. The subjects were untreated, unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma with low PD-L1 expression. Patients were randomly assigned to receive chemoradiation or chemotherapy in combination with Tislelizumab at a ratio of 1: 1. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population. We hypothesized that in advanced esophageal squamous cell carcinoma patients with low PD-L1 expression, chemoradiation versus chemotherapy in combination with Tislelizumab will significantly improve PFS.

- Primary Outcome Measures
Name Time Method Progression-Free Survival (PFS) Approximately 40 months from date of the first participant randomization PFS is defined as the time from the date of randomization to the date of first documentation of disease progression assessed by the investigator per RECIST v1.1 or death, whichever occurs first
- Secondary Outcome Measures
Name Time Method Overall Survival (OS) Approximately 40 months from date of the first participant randomization Overall Survival (OS) is defined as the time between the date of randomization and the date of death. For participants without documentation of death, OS will be censored on the last date the subject was known to be alive.
Objective Response Rate (ORR) Approximately 40 months from date of the first participant randomization Objective response rate (ORR) is defined as the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR). Best overall response (BOR) is defined as the best response designation as determined by BICR, recorded between the date of randomization and the date of objectively documented progression (per RECIST 1.1) or the date of subsequent anti-cancer therapy (including tumor-directed radiotherapy and tumor-directed surgery), whichever occurs first. Partial response is defined as at least a 30% decrease in the sum of diameters of target lesions. Complete response is defined as the disappearance of all target lesions and the reduction of any pathological lymph nodes to \<10 mm.
Duration of Response (DOR) Approximately 40 months from date of the first participant randomization DOR is defined as the time from the first determination of an objective response until the first documentation of progression assessed by the investigator per RECIST v1.1 or death, whichever comes first
Number of participants experiencing Adverse Events (AEs) Approximately 40 months from date of the first participant randomization AEs are documented according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4
