Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	maximal tolerance dose (MTD) of RC48-ADC combined with Pyrotinib	Maximum-tolerated dose (MTD) was defined as the highest dose level at which no more than one of six patients experienced DLT during the DLT assessment window.	DLT will be evaluated on 28 days of observation period
Secondary	Overall response rate (ORR)	The objective response rate will be mainly analyzed by investigators according to the RECIST 1.1 standard tumor evaluation.	Up to approximately 3 years
Secondary	Disease control rate (DCR)	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.	Up to approximately 3 years
Secondary	Duration of relief (DOR)	DOR is defined as the time from the first documented objective response (CR or PR) to the first documented disease progression or death.	Up to approximately 3 years
Secondary	Progression-free survival (PFS)	Progression-free survival (PFS) refers to the time from the date of randomization to the first researcher's evaluation of disease progression or death.	Up to approximately 3 years
Secondary	Overall survival (OS)	The objective response rate will be mainly analyzed by investigators according to the RECIST 1.1 standard tumor evaluation	Up to approximately 3 years
