- Positive pregnancy test at study screening for female participants of childbearing potential.
- QT interval corrected using Fridericia formula (QTcF) >450 milliseconds at screening or pre-dose.
- Hypokalemia (<3.5 millimoles per liter [mmol/L]), hypocalcemia (<2.0 mmol/L) or hypomagnesemia (<0.5 mmol/L) at screening or pre-dose.
- Family history of sudden death or of congenital prolongation of the QT interval or known congenital prolongation of the QT-interval or any clinical condition known to prolong the QT interval e.g., participants with a history of symptomatic cardiac arrhythmias including atrial fibrillation or with clinically relevant bradycardia.
- Participant not suitable for participation, whatever the reason, as judged by the Investigator, included medical or clinical conditions, or participants potentially at risk of noncompliance to study procedures or unable to drink.
