Study Details
Study Description
Brief Summary
This study is a randomized, double-blind, placebo-controlled, multicenter phase III clinical study to evaluate the efficacy and safety of carrelizumab plus concurrent chemoradiotherapy compared with placebo plus concurrent chemoradiotherapy in the treatment of patients with inoperably advanced esophageal cancer, and to explore the relationship between PD-L1 expression and efficacy in tumor tissues. Experimental group: carrelizumab in combination with concurrent chemoradiotherapy PD-1: carrelizumab: 200 mg/3W Chemotherapy: Paclitaxel: 50 mg/m2/W Cisplatin: 25mg/m2/W Radiotherapy: 50.4 Gy / 28 f Chemotherapy drugs are used for 5 cycles, and carrelibizumab is used for up to 24 months until PD or is intolerable Control group: placebo-resistant in combination with chemoradiotherapy placebo: 200 mg/3 W Chemotherapy: Paclitaxel: 50 mg/m2/W Cisplatin: 25mg/m2/W Radiotherapy: 50.4 Gy / 28 f Chemotherapy drugs are used for 5 cycles, and carrelibizumab is used for up to 24 months until PD or is intolerable

Outcome Measures
Primary Outcome Measures
- PFS evaluated by IRC [up to 2 years]
IRC stands for Independent Review Committee Assessment，Progression-free disease as assessed by an independent review committee Progression-free survival refers to the time from randomization to the first occurrence of disease progression or death from any cause
Secondary Outcome Measures
- OS Overall Survival [up to 2 years]
Overall survival was measured from the initiation of chemotherapy to the date of the last follow-up or death.
- ORR [through study completion, an average of 18 month]
Proportion of patients with reduction in tumor burden of a predefined amount, including complete remission and partial remission
- Progression-free survival evaluated by Researchers [up to 2 years]
The PFS was calculated from the initiation of chemotherapy to the date of disease progression or death.
