Measure
Dasatinib 100 mg
Participants were administered an oral dose of 100 mg dasatinib tablet once daily for a period of 4 weeks. Initially, 3 participants were treated at one dose level. If no dose limiting toxicity (DLT) was observed, the dose was escalated to next higher level. If a DLT was observed among 1 of 3 treated participants in the first course at a dose level, 3 participants were additionally enrolled and treated at the same dose level. If no further DLT was observed during the first course in these additional participants, the dose was escalated to next higher dose level. Dose was not escalated above 200 mg daily.
Dasatinib 150 mg
Participants were administered an oral dose of 150 mg dasatinib tablet once daily for a period of 4 weeks. Initially, 3 participants were treated at one dose level. If no DLT was observed, the dose was escalated to next higher level. If a DLT was observed among 1 of 3 treated participants in the first course at a dose level, 3 participants were additionally enrolled and treated at the same dose level. If no further DLT was observed during the first course in these additional participants, the dose was escalated to next higher dose level. Dose was not escalated above 200 mg daily.
Dasatinib 200 mg
Participants were administered an oral dose of 200 mg dasatinib tablet once daily for a period of 4 weeks. Initially, 3 participants were treated at one dose level.

Standard 12-lead ECG was used to record selected ECG parameters like RR interval (the time between the two R waves in ECG), PR interval (interval measured from the beginning of the P wave to the beginning of the QRS complex; QRS complex is the name for some of the deflections seen on a typical ECG)), QRS duration, QT interval (time between onset of ventricular depolarization and end of ventricular repolarization), QT interval corrected for heart rate using Bazett's (QTcB) and Fridericia's (QTcF) formulas.
