2. Currently participating in another study unless it is an observational, non-interventional clinical study or a follow-up period of an interventional study

3. Received systemic antineoplastic therapy ( e.g. chemotherapy, radiotherapy, immunotherapy) within 4 weeks prior to the first dose of investigational product; received small-molecule anticancer agents within 2 weeks prior to the first dose of investigational product

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of subjects with dose limiting toxicities (DLTs)	DLTs will be assessed during the first three weeks of treatment. DLTs are defined as toxicities that meet pre-defined severity criteria, and assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the DLT observation period.	During the first three weeks
Primary	Number of subjects with adverse events (AEs)	AE refers to any untoward medical occurrence or deterioration of existing medical event after the subject signed the ICF, whether or not considered related to the study treatment.	From the time of informed consent signed through 90 days after the last dose of study drug.
Primary	Objective Response Rate (ORR)	ORR is defined as the proportion of subjects with CR or PR (based on RECIST Version 1.1).	Up to 2 years
Secondary	Progression free survival (PFS)	PFS is defined as the time from the start of treatment until the first documentation of disease progression or death due to any cause, whichever occurs first (based on RECIST Version 1.1).	Up to 2 years
Secondary	Disease control rate (DCR)	DCR is defined as the proportion of subjects with CR, PR, or SD (based on RECIST Version 1.1).	Up to 2 years
Secondary	Duration of response (DoR)	Duration of response is defined as the duration from the first documentation of objective response to the first documented disease progression (based on RECIST Version 1.1) or death due to any cause, whichever occurs first.	Up to 2 years
Secondary	Time to response (TTR)	Time to response (TTR) is defined as the time from the start of the treatment to the first objective tumor response observed for patients who achieved CR or PR (based on RECIST Version 1.1).	Up to 2 years
Secondary	Time to progression (TTP)	Time to progression (TTP) is defined as the time from the start of the treatment to the documentation of disease progression (based on RECIST Version 1.1).	Up to 2 years
Secondary	Overall survival (OS)	OS defined as the time from the first dose to death from any cause.	Up to 2 years
