Measure Type Secondary
Measure Title Time-matched Change From Baseline in the Study Specific Corrected QT Interval (QTcP)
Measure Description Three electrocardiograms (ECG) were obtained pre-dose and 2, 4, 6, and 8 hours post-dose at Days 1 and 15 of Cycle 1 and again pre-dose and 4 hours post-dose at various Cycles throughout treatment. Five baseline triplicate ECGs were obtained before the start of treatment at the same time points used during treatment. Reported is the largest mean time-matched QTcP change from baseline. QTcP=QT/(60/heart rate)^β (β=mean [calculated separately for males and females] log-transformed QT versus log-transformed RR regression slopes using all available pre-treatment (baseline) ECG values.
Time Frame Pre-dose Cycle 1 Day 1 to pre-dose Cycle 6 Day 1  

Population Description

Electrocardiogram (ECG) evaluable population: All treated patients who had a baseline ECG and at least one ECG during treatment.
