- Clinically significant Electrocardiogram abnormality: Evidence of a clinically significant abnormality in the 12-lead ECG performed during screening. The Investigator will determine the clinical significance of each abnormal ECG finding in relation to the subject's medical history and exclude subjects who would be at undue risk by participating in the trial. An abnormal and clinically significant finding is defined as a 12-lead tracing that is interpreted as, but not limited to, any of the following: Atrial fibrillation (AF) with rapid ventricular rate >20 Beats Per Minute (BPM); sustained or non-sustained ventricular tachycardia (VT); Second degree heart block Mobitz type II and third degree heart block (unless pacemaker or defibrillator had been inserted); QT interval corrected for heart rate by Fridericia's formula (QTcF) >=500 milliseconds (msec) in subjects with QRS <120 msec and QTcF >=530 msec in subjects with QRS >=120 msec.
