Part 1, Dose Escalation Phase: Number of Participants With Dose-limiting Toxicities (DLTs) Based on National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03 |
DLTs were defined as any of the following toxicities: Hematology, gastrointestinal, renal, hepatic or nonhematologic toxicities occurring during Cycle 1 in Dose Escalation Phase only and judged by the investigator as related to study drug. This included any Grade 4: neutropenia that does not resolve to Grade less than or equal to (<=) 2 within 7 days, thrombocytopenia, anemia of any duration, diarrhea and/or vomiting irrespective of prophylaxis or appropriate treatment; Grade 3: thrombocytopenia requiring transfusion, thrombocytopenia and clinically significant bleeding, anemia if transfused or if lasting for more than 7 days, nausea, vomiting and/or diarrhea lasting more than 72 hours despite the use of optimal anti-emetic/antidiarrheal treatment, bilirubin, fatigue lasting less than 1 week, elevations in biochemistry laboratory values without associated clinical symptoms that last for <=7 days; Grade greater than or equal to (>=) 3 serum creatinine. |

Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) |
A TEAE was defined as an adverse event (AE) that emerges during treatment, having been absent at pretreatment (Baseline) or reemerges during treatment, having been present at pretreatment (Baseline) but stopped before treatment, or worsens in severity during treatment relative to the pretreatment state, when the AE was continuous. An SAE was any untoward medical occurrence that at any dose: Resulted in death, was life-threatening (that is, the participant was at immediate risk of death from the AE as it occurred; this does not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug). |

Part 2, Dose Expansion Phase: Objective Response Rate (ORR) Based on Modified Response Evaluation Criteria in Solid Tumors (mRECIST) v1.1 |
ORR was defined as the percentage of participants achieving a best overall confirmed response of partial response (PR) or complete response (CR) (PR + CR), from the first dose date until disease progression/recurrence. Responses (PR or CR) were confirmed no less than 4 weeks after the initial response. CR was defined as the disappearance of all target lesions and non-target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in the short axis to less than 10 millimeter (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. The tumor assessment was done using number of lesions based on modified RECIST v1.1 for assessing tumor burden up to 10 target lesions with up to 5 target lesions per organ. |
From the first dose date until disease progression/recurrence or up to approximately 36.7 months |
|

Part 2, Dose Expansion Phase: Duration of Response (DOR) Based on Modified Response Evaluation Criteria in Solid Tumors (mRECIST) v1.1 |
DOR was defined as the time from the date of first documented CR or PR based on modified RECIST v1.1 until the first documentation of disease progression (PD) as determined by the investigator or death, whichever comes first. CR was defined as the disappearance of all target lesions and non-target lesions. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. PD was defined as at least a 20% increase in the sum of long diameter (LD) of target and non-target lesions as compared with the smallest sum of LD and the increase of LD was at least 5 mm (including new lesions). |
From the date of first documented CR or PR up to approximately 36.7 months |

Part 2, Dose Expansion Phase: Progression-free Survival (PFS) Based on Modified Response Evaluation Criteria in Solid Tumors (mRECIST) v1.1 |
PFS was defined as the time from the first dose date to the date of the first documentation of PD as determined by the investigator or death (whichever occurs first). PD was defined as at least a 20% increase in the sum of LD of target and non-target lesions as compared with the smallest sum of LD and the increase of LD was at least 5 mm (including new lesions). |
From the first dose date to the date of the first documentation of PD as determined by the investigator or death (whichever occurs first) up to approximately 36.7 months |

Part 2, Dose Expansion Phase: Overall Survival (OS) |
OS was defined as the time from the first dose date to the date of death. OS was assessed using Kaplan-Meier method. The time of death was censored for participants who were without death information at the time of OS analysis. |
From the date of first dose of study drug until date of death from any cause (up to approximately 36.7 months) |

Part 2, Dose Expansion Phase: Time to Response (TTR) Based on Modified Response Evaluation Criteria in Solid Tumors (mRECIST) v1.1 |
TTR was defined as the time from the first dose date to the date of first documented CR/PR. CR was defined as the disappearance of all target lesions and non-target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in the short axis to less than 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 of diameters. |
