Duration of Response (DOR) As Assessed by The Investigator Based on RECIST v1.1
DOR was defined as the time interval between the date of the earliest qualifying response (CR or PR) and the date of PD or death (whichever occurred earlier). DOR was estimated using the Kaplan-Meier method. Per RECIST v1.1., CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive disease was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.
Time frame: From the date of earliest response to the date of first documentation of disease progression or death, whichever occurred first (up to 35 months)
Population: Analysis was performed on Efficacy-Evaluable Analysis Set (EFF) on the subset of participants with a response.

Number of Participants With Treatment Emergent Adverse Events (TEAEs), Treatment Emergent Serious Adverse Events (TESAEs) and TEAEs Leading to Treatment Discontinuation and Modification
A TEAE was defined as adverse event (AE) that had an onset date or a worsening in severity from baseline (pre-treatment) on or after the first dose of study drug(s) and up to 30 days following study drug(s) discontinuation or initiation of new anticancer therapy, whichever occurs first determined according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. SAE: any untoward medical occurrence at any dose: resulted in death; was life threatening; required prolong inpatient hospitalization; resulted in persistent or significant disability/incapacity; resulted in a congenital anomaly/birth defect or was considered a significant medical event by the investigator.
Time frame: From the date of the first dose of study drug up to 30 days after last dose of study drug (maximum time on treatment was 12 months)
Population: Analysis was performed on safety analysis set which included all participants who received at least 1 dose of any study drug (any component for the combination therapy).

Objective Response Rate (ORR) as Assessed by the Investigator and Central Site Imaging Facility Based on Immune Related Response Evaluation Criteria in Solid Tumors (iRECIST)
ORR was defined as the percentage of participants achieving the BOR of immune complete response (iCR) or partial response (iPR). The 95% CI was estimated using the Clopper-Pearson method. Per iRECIST, iCR was defined as disappearance of all target and non-target lesions and any pathological lymph nodes must be \<10 mm in the short axis. iPR was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters. iRECIST is a modification to RECIST that considers unique patterns of atypical response in immunotherapy and enables treatment beyond initial radiographic progression.
Time frame: Response was assessed every 6 weeks for the first year and approximately every 9 weeks thereafter through December 2022; up to 27 months
Population: Analysis was performed on Efficacy-Evaluable Analysis Set (EFF).

Objective Response Rate (ORR) as Assessed by the Investigator and Central Site Imaging Facility Based on Modified Response Evaluation Criteria in Solid Tumors (mRECIST)
ORR was defined as the percentage of participants achieving the BOR of CR or PR. The 95% CI was estimated using the Clopper-Pearson method. Per modified RECIST (mRECIST), CR was defined as the disappearance of any intratumoral arterial enhancement in all target lesions. PR: at least a 30% decrease in the sum of diameters of viable (contrast enhancement in the arterial phase) target lesions, taking as reference the baseline sum of the diameters of target lesions.
Time frame: Response was assessed every 6 weeks for the first year and approximately every 9 weeks thereafter through December 2022; up to 27 months
Population: Analysis was performed on Efficacy-Evaluable Analysis Set (EFF).
