- Objective remission rate (ORR) [ Time Frame: 2 years ]ORR is defined as the percentage of subjects who have achieved complete response and partial response according RECIST 1.1
- Progression-free survival (PFS) [ Time Frame: 2 years ]PFS is defined as the time between date of first dose of study therapy and date of progression or death, whichever occurs first, will be computed for response evaluable subjects. Subjects will be censored at time of subsequent therapy
- Overall survival (OS) [ Time Frame: 2 years ]Overall survival (OS) is defined as the time from first dose of study therapy to the date of death (any cause). Subjects who are alive will be censored at the last known time that the subject was alive
- Disease control rate (DCR) [ Time Frame: 2 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
- Duration of relief (DOR) [ Time Frame: 2 years ]DOR is defined as the time from the first documented objective response (CR or PR) to the first documented disease progression or death
