Primary Outcome Measures

Name	Time	Method
Objective Response Rate (ORR) Using Immune RECIST (iRECIST) Criteria	10 months	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.

Secondary Outcome Measures

Name	Time	Method
Number of Participants Experiencing Grade 3 or Above Drug-related Toxicities	13 months	Defined using NCI CTCAE v5.0
Overall Response Rate (ORR) Using RECIST 1.1 Criteria	10 months	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.
