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)

Percentage of Participants With Treatment-emergent Adverse Events (AEs), by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) (Version 4.0) Grade
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.
Time frame: Baseline up to 28 days post last dose of study medication (maximum duration: 14 cycles [each cycle of 28 days])

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).
Time frame: Baseline up to Cycle 14 (each cycle 28 days)
Population: This OM was planned for expansion cohort only. Since none of the participants were enrolled in expansion cohort, no data was collected for progression free survival and thus the outcome measure was not performed.
Time to Progression (TTP)
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. TTP (days) was calculated as (first event date minus the date of first dose of study medication plus 1).
Time frame: Baseline up to Cycle 14 (each cycle 28 days)
Population: This OM was planned for expansion cohort only. Since none of the participants were enrolled in expansion cohort, no data was collected for time to progression and thus the outcome measure was not performed.
