MeasureTime frameDescription
Overall response rate (ORR) assessed by InvestigatorBaseline up to 18 monthsPercentage of participants achieving complete response (CR) and partial response (PR) assessed by investigator.
Progression-free survival (PFS)Baseline up to 18 monthsPFS was defined as the time from the date of study enrollment to the date of the first of the following events, objective disease progression or death due to any cause.
Disease control rate(DCR)Baseline up to 18 monthsPercentage of subjects achieving complete response (CR) and partial response (PR) and stable disease (SD).
Overall Survival (OS)Baseline up to 24 monthsOS defined as the time from the first dose to death from any cause. Survival time was censored at the date of last contact for patients who were still alive or lost to follow-up.
