Outcomes
Primary Outcomes
Phase 1b: Number of Participants Experiencing Dose Limiting Toxicity
Time Frame: Day 1 to Day 21 of Cycle 1 (each cycle is 21 days)
Dose limiting toxicity (DLT) was defined as toxicities at any dose level and judged to be related to the study treatment by investigator and/or the sponsor. DLTs included Grade 4 neutropenia for more than 7 days; Grade greater than or equal to (\>=) 3 febrile neutropenia for more than 1 day; Grade 4 thrombocytopenia or Grade 3 thrombocytopenia with non-traumatic bleeding; Grade \>= 3 uncontrolled nausea/vomiting and/or diarrhea despite adequate and optimal treatment and Grade \>= 3 any non-hematological adverse event (AE), except the aforementioned gastrointestinal events and alopecia. Number of participants who experienced DLT during phase 1b were reported.
Phase 1b: Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious TEAEs
Time Frame: Baseline up to Day 30 after the last dose of study treatment, assessed up to 94 weeks
An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. 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. Treatment-emergent are events between first dose of study drug and assessed up to 94 weeks. TEAEs include both Serious TEAEs and non-serious TEAEs.
Phase 2: Time to Progression (TTP) Based on Tumor Assessment by an Independent Review Committee (IRC)
Time Frame: From randomization to date of the observation of radiological progressive disease, assessed up to maximum 3.8 years
TTP was defined as the time in months from randomization to date of the observation of radiological progressive disease (PD) (based on Response Evaluation Criteria in Solid Tumors \[RECIST\] v1.1) assessed by an IRC. PD is defined as at least 20 percent (%) increase in sum of diameters of target lesions, taking as reference as smallest sum on study; and/or unequivocal progression of existing non-target lesions and/or the presence of new lesions. The sum must demonstrate an absolute increase of at least 5 millimeter (mm).
