Arm && Interventions

Group	Intervention	Description
MRG003 + Pucotenlimab	MRG003 + Pucotenlimab	-
Chemotherapy Arm	Gemcitabine, Docetaxel, or Capecitabine	Mono-chemotherapy as selected by investigator

Primary Outcome Measures

Name	Time	Method
Progression Free Survival (PFS) as assessed by BIRC	Baseline to study completion (up to 33 months)	PFS is defined as the duration from the start of treatment to the onset of tumor progression or death of any cause.
Overall Survival (OS)	Baseline to study completion (up to 48 months)	OS is defined as the duration from the start of treatment to death of any cause.

Secondary Outcome Measures

Name	Time	Method
Serious Adverse Events (SAEs)	Baseline to 30 days after the last dose of study treatment	Adverse events that are fatal, life-threatening, or result in hospitalization or prolonged hospitalization, persistent or significant disability/incapacity/substantial disruption of the ability to lead a normal life, congenital anomaly/birth defect or major medical events or reactions.
Adverse Events (AEs)	Baseline to 30 days after the last dose of study treatment	Any reaction, side effect, or untoward event that occurs during the course of the clinical trial whether or not the event is considered related to the study drug.
Objective Response Rate (ORR)	Baseline to study completion (up to 48 months)	ORR is defined as the proportions of patients with a complete response (CR) and partial response (PR). ORR will be assessed according to RECIST v1.1.
Immunogenicity (ADA)	Baseline to 14 days after the last dose.	The proportion of patients with positive ADA results.
Disease Control Rate (DCR)	Baseline to study completion (up to 48 months)	DCR is defined as the proportion of subjects achieving CR, PR, and stable disease (SD) after treatment.
Progression Free Survival (PFS) as assessed by investigator	Baseline to study completion (up to 33 months)	PFS is defined as the duration from the start of treatment to the onset of tumor progression or death of any cause.
