Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Progression-free survival (PFS), evaluated by an independent efficacy evaluation committee
Time Frame: within approximately 3 years
|
Progression-free survival (PFS) refers to the time from the date of randomization to the first researcher's evaluation of disease progression or death (calculated by the event that occurred first).
The disease progression will be evaluated by the researchers according to the RECIST 1.1 standard.
|
within approximately 3 years
|

The disease progression will be evaluated by the researchers according to the RECIST 1.1 standard.
|
within approximately 3 years
|
Objective remission rate (ORR)
Time Frame: within approximately 3 years
|
The objective response rate will be mainly analyzed by the independent efficacy evaluation committee according to the RECIST 1.1 standard tumor evaluation (the evaluation by the investigator will also be performed).
|
within approximately 3 years
|
Duration of relief (DOR)
Time Frame: within approximately 3 years
|
DOR is defined as the time from the first documented objective response (CR or PR) to the first documented disease progression or death
|
within approximately 3 years
|
Disease control rate (DCR)
Time Frame: within approximately 3 years
|
Disease control rate (DCR) is defined as cases where objective remission (assessed as complete remission or partial remission according to RECIST 1.1 standard) or stable disease during the study.
|

|
Tumor progression time (TTP)
Time Frame: within approximately 3 years
|
