Arm && Interventions

Group	Intervention	Description
TQB2858 injection	TQB2858 injection	TQB2858 injection (1800mg intravenous(iv), on day 1 of every 3 weeks)

Primary Outcome Measures

Name	Time	Method
Overall response rate (ORR)	up to 48 weeks	Objective response rate refers to the percentage of complete response (CR) or partial response (PR) subjects determined by the investigator based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or modified RECIST1.1 for immune based therapeutics (iRECIST) (CR and PR under iRECIST criteria can occur after imaging disease progression).

Secondary Outcome Measures

Name	Time	Method
Disease control rate (DCR)	up to 48 weeks	Disease control rate refers to the percentage of subjects with CR, PR, or stable disease (SD) of 6 weeks or more as determined by RECIST 1.1 or iRECIST (CR, PR, SD under iRECIST criteria can occur after imaging disease progression).
Overall survival (OS)	Baseline up to die	Overall survival defined as the time from enrollment to death from any cause.
Progression-Free Survival (PFS)	up to 48 weeks	PFS will be defined as median number of months from the date of randomization until the first documented sign of disease progression or death due to any causes, whichever occurs first.
Duration of Response (DOR)	up to 48 weeks	DOR will be defined as median number of months from date of first documented objective response until first documented sign of disease progression or death due to any causes.
