One participant can have more than one ECG data meeting pre-specified criteria.	From start of study treatment (Cycle 1 Day 1) up to 28 days after the last administration of the investigational product, up to approximately 275 weeks
Number of Participants With Left Ventricular Ejection Fraction (LVEF) Meeting Pre-specified Criteria	Echocardiogram or multigated acquisition scan were performed to monitor LVEF. Pre-specified criteria included shift from baseline normal to post-baseline below lower limit of normal (LLN) >=20-point decrease from baseline in LVEF% .	From start of study treatment (Cycle 1 Day 1) up to 28 days after the last administration of the investigational product, up to approximately 275 weeks

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Objective Response (Cohort 1)-Final Analysis	ORR was defined as the percentage of participants with a best overall confirmed response of CR or PR according to RECIST version 1.1 relative to the total participants in the analysis population. CR was defined as the disappearance of all target lesions and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR was defined as a >=30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. ICR was used for disease progression assessment.	From first dose (Cycle 1 Day 1) to documented disease progression by ICR (up to 271 weeks of treatment exposure)
