Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare Arm A relative to Arm B on event-free survival (EFS);Secondary Objective: To compare Arm A relative to Arm B on overall survival (OS) To compare Arm A relative to Arm B on pathological complete response (pCR) rate To compare Arm A relative to Arm B on the proportion of patients who undergo gastrectomy or gastrophagectomy To compare Arm A relative to Arm B on the rate of complete resection (R0) To compare Arm A relative to Arm B on metastasis-free survival (MFS) and disease-specific survival (DSS) To compare Arm A relative to Arm B on disease-free survival in patients who undergo R0 resection surgery To compare Arm A relative to Arm B on EFS24, EFS36, OS24, OS36, DFS24, and DFS36 To compare Arm A relative to Arm B on efficacy endpoints by PD-L1 expression To compare Arm A relative to Arm B on disease-related symptoms, impacts, and HRQoL To evaluate PK of Arm A and Arm B To assess the immunogenicity of Arm A and Arm B;Primary end point(s): EFS (event free survival);Timepoint(s) of evaluation of this end point: EFS will be analyzed at the end of the study using a stratified log-rank test adjusting for the stratification factors of geographic region, clinical lymph node status, and PD-L1 expression status. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): OS, pCR rate Surgery rate R0 resection rate MFS, DSS, DFS EFS24, EFS36, OS24, OS36,DFS24, DFS36 EORTC QLQ-C30, QLQ-STO22, and IL38;Timepoint(s) of evaluation of this end point: The primary and key secondary endpoints will be evaluated at an interim analysis and all endpoints will be evaluated at the final analysis. | — |
