Subjects with corrected QT interval using Fridericia's formula exceeding the upper limit of normal (male ≥450 ms or female ≥460 ms), or with abnormal electrocardiogram findings considered clinically significant by the study physician, or with a history of arrhythmias or syncope associated with arrhythmias, or using a pacemaker. 5.

Note: Diseases include, but are not limited to: heart failure; hypokalemia; atrial fibrillation, atrial flutter, premature atrial contractions, premature ventricular contractions, non-sustained or sustained ventricular tachycardia; bradycardia or sick sinus syndrome; personal or family history of any cardiac conduction abnormalities; personal or family history of long QT syndrome (LQTS); or family history of sudden death; 5. Subjects with a history of smoking or alcohol abuse (consumption of 14 units of alcohol per week within the 4 weeks prior to screening: 1 unit = 285 mL beer, or 25 mL spirits, or 150 mL wine; daily smoking ≥ 5 cigarettes) or other substance or drug abuse within the past year; 6.
