Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR) Using Immune RECIST (iRECIST) Criteria	ORR is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on immune Response Evaluation Criteria in Solid Tumors (iRECIST) at any time during the study. CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.	10 months
Secondary	Overall Response Rate (ORR) Using RECIST 1.1 Criteria	Objective Response Rate (ORR) is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on RECIST 1.1 criteria. CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions. Subjects who discontinue due to toxicity or clinical progression prior to post-baseline tumor assessments will be considered as non-responders.	10 months
Secondary	Number of Participants Experiencing Grade 3 or Above Drug-related Toxicities	Defined using NCI CTCAE v5.0	13 months
