Name	Time	Method
Objective response rate (ORR)	12 months	the proportion of participants who got a complete response (CR) and partial response (PR) according to RECIST v1.1.

Secondary Outcome Measures

Name	Time	Method
Incidence of Treatment-Emergent Adverse Events	from first dose to within 30 days after the last dose	Incidence of Treatment-Emergent Adverse Events were evaluated in accordance with the NCI CTC AE Version 5.0
Duration of response (DOR)	time from CR or PR (RECIST v1.1) achievement with investigational therapy, until documented progression, relapse, or death due to disease progression	time from CR or PR (RECIST v1.1) achievement with investigational therapy, until documented progression, relapse, or death due to disease progression
Disease Control Rate (DCR)	12 months	the percentage of patients who have achieved CR, PR, and SD.
Progression-Free Survival (PFS)	From date of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months	the period from treatment initiation until the date of disease progression, death, or study cutoff, whichever occurred first.
Overall survival(OS)	From date of treatment until the date of death from any cause, whichever came first, assessed up to 100 months	OS was defined as the time from the date of treatment to the date of death due to any cause. For subjects who were alive or lost to follow-up by the data analysis cut-off date, survival was censored at the subject's last known survival time.
