Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective response rates (ORR)	ORR is the proportion of subjects with complete response(CR) or partial response(PR) , based on RECIST v1.1	Up to approximately 2 years
Primary	Number of participants with adverse events (AEs)	An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment.	Up to approximately 2 years
Secondary	Disease control rate (DCR)	Disease control rate (DCR) is defined as the proportion of subjects with CR, PR, or stable disease(SD) based on RECIST V1.1	Up to approximately 2 years
Secondary	Duration of response (DOR)	DOR is defined for participants who had an objective response as the time from the first occurrence of a documented unconfirmed response (CR or PR) to the date of disease progression per RECIST v1.1 or death from any cause, whichever occurred first	Up to approximately 2 years
Secondary	Time to response (TTR)	TTR is defined for participants who had an objective response as the time from the start of treatment to the first occurrence of a documented unconfirmed response (CR or PR) .	Up to approximately 2 years
Secondary	Progression-free survival (PFS)	PFS is defined as the time from the start of treatment till the first documentation of disease progression (per RECIST v1.1 criteria) assessed by the investigator or death due to any cause (whichever occurs first).	Up to approximately 2 years
Secondary	Overall survival (OS)	Overall survival is defined as the time from the start of treatment until death due to any cause.	Up to approximately 2 years
