Outcome Measures
Primary Outcome Measures
- ORR [WEEK 25]
The best overall response rate (ORR24: performed at the 25th week): According to the Solid Tumor Efficacy Evaluation Standard (RECIST) 1.1, the proportion of CR and PR subjects from the first evaluation (baseline) to the 25th week of treatment (after the completion of 8 treatment cycles) (note: including unconfirmed response).
Secondary Outcome Measures
- DCR [WEEK 25]
Disease control rate (DCR: in the 25th week): DCR=CR+PR+SD。
- PFS [WEEK 52]
Progression-free survival (PFS: the 52nd week): according to RECIST1.1, the time from the date of randomization to the date of disease progression or all-cause death (whichever occurs first). If the subjects did not have the above events, the PFS would be closed to the date of the last full tumor evaluation.
- OS [WEEK 52]
Total survival rate (OS rate: performed at the 52nd week): defined as the percentage of subjects who survived at 51 weeks after randomization.
