The CR is defined as disappearance of all target lesions (TLs) and non-target lesions (NTLs) present at baseline, any pathological lymph nodes selected as TLs or non-pathological lymph nodes of NTLs must have a reduction in short axis to \< 10mm. The PR is defined as at least a 30% decrease in the sum of diameters of TLs, taking as reference the baseline sum of diameters as long as criteria for progressive disease (PD) are not met. PD is defined as "≥ 20% increase in the sum of diameters of TLs and an absolute increase of ≥ 5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters and unequivocal progression of existing NTLs. Percentage of participants with OR is reported.

SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD is defined as a ≥ 20% increase in the sum of diameters of TLs and an absolute increase of ≥ 5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters. Percentage of participants who have disease control at 16 weeks is reported.
Time frame: Baseline (Days -28 to -1) through 90 days post last dose (76.14 weeks)
Progression Free Survival (PFS) According to RECIST v1.1

Median number of months of PFS assessed via Kaplan-Meier method is reported. Here, number of participants analyzed denotes those participants who had PFS event.
Time frame: Baseline (Days -28 to -1) through 90 days post last dose (76.14 weeks)
Overall Survival (OS)
The OS is defined as the time from the date of first dose until death due to any cause regardless of whether the participant withdraws from study therapy or receives another anti-cancer therapy.
