16. Personal or family history of serious ventricular arrhythmia, or QT interval corrected for heart rate (QTc) ≥470 ms (Bazett's formula).
17. Any other prior or current medical condition or extenuating circumstance that, in the Investigator's opinion, could jeopardize patient safety or interfere with the objectives of the study.
