Objective response rate was defined as percentage of participants with either a confirmed complete response (CR) or partial response (PR) from first administration of study treatment to first observation of progressive disease (PD). CR: Disappearance of all target and non-target lesions. PR: At least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum of their diameters, and no unequivocal progression of non-target lesions. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on the study, or unequivocal progression of non-target lesions, or appearance of any new lesion.
DLT is defined as drug-related: Neutropenia Grade 4 for greater than (\>) 7 days' duration; Febrile neutropenia (that is \[i.e.\] absolute neutrophil count less than (\< ) 1000 per millimeter cube (mm\^3) with single temperature of \> 38.3°degree Celsius or a sustained temperature of greater than or equal to (\>=) 38 degree Celsius for more than 1 hour; Infection (documented clinically or microbiologically) with Grades 3 or 4 neutropenia; Thrombocytopenia \>= Grade 3; Grade \>= 3 non-hematological AEs.
An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether considered related to the study intervention or not. A serious AE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAEs were defined as events with onset date or worsening during the on-treatment period. TEAEs included both serious and non-serious TEAEs. Treatment-related TEAEs is defined as reasonably related to the study intervention.
Vital signs included body temperature, heart rate, systolic and diastolic blood pressure and respiration rate. Number of participants with clinically significant changes from baseline in vital signs were reported. Clinical significance was decided by Investigator.
ECG parameters included PR interval, RR interval, QT interval, QRS duration, QTc intervals (derived using Fridericia's correction method) and heart rate. A 12-lead ECG was recorded with the participant in a supine position after a rest of at least 5 minutes using an ECG machine. Clinical significance was decided by investigator. Number of participants with clinically significant changes from baseline in 12-Lead ECGs were reported.
The laboratory measurements included hematology and biochemistry. Number of participants with clinically significant abnormalities with Grade greater than or equals to (\>=) 3 in laboratory values reported as TEAEs as per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0 graded from Grade 1 to 5. Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening; Grade 5: Death. Clinically Significance was decided by investigator.
