Grades as per NCI CTCAE, v4.0 were classified as: Grade 1- mild, Grade 2- moderate, Grade 3- severe, Grade 4- life threatening, and Grade 5- death.

Percentage of Participants With Treatment-emergent Adverse Events (AEs), by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) (Version 4.0) GradeBaseline up to 28 days post last dose of study medication (maximum duration: 14 cycles [each cycle of 28 days])An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent AEs are events occurred between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. If the same participant in a given treatment had more than one occurrence in the same preferred term event category, only the worst CTCAE grade was reported.

Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm. PFS (days) was calculated as (first event date minus the date of first dose of study medication plus 1).
Time to Progression (TTP)Baseline up to Cycle 14 (each cycle 28 days)Time from Cycle 1/Day 1 to first documentation of disease progression. Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm.

Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm. DR was calculated as (the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first objective response that was subsequently confirmed plus 1).

Duration from date of first documentation of objective response to date of first documentation of disease progression or death. Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm.

Number of Participants With Increase From Baseline in Corrected QT Using Fridericia's Formula (QTcF) Interval

Triplicate 12-lead electrocardiogram (ECG) measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. The time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole (QT) was corrected for heart rate (QTc). QTc using Fridericia's formula (QTcF) was calculated. Participants with maximum increase from baseline of less than (\<) 30 millisecond (msec), 30 to \<60 msec and \>=60 msec were summarized.

Time frame: Baseline up to Cycle 14 (each cycle 28 days)

Population: QTc Analysis Set: all enrolled participants who had at least 1 ECG assessment after receiving at least 1 dose of study medication.

Percentage of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Confirmed responses were those that persisted on repeat imaging study at least 4 weeks after initial documentation of response. CR was defined as complete disappearance of all target lesions with the exception of nodal disease.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent AEs are events occurred between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. If the same participant in a given treatment had more than one occurrence in the same preferred term event category, only the worst CTCAE grade was reported. Grades as per NCI CTCAE, v4.0 were classified as: Grade 1- mild, Grade 2- moderate, Grade 3- severe, Grade 4- life threatening, and Grade 5- death.

Progression-Free Survival (PFS)

Time from Cycle 1/Day 1 to first documentation of disease progression or to death due to any cause, whichever occurred first. Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm. PFS (days) was calculated as (first event date minus the date of first dose of study medication plus 1).
