bradycardia or brady arrhythmia within the last 12 months.

- The participant is taking QT-prolonging drugs or drugs known to increase the risk of
torsades de pointes (TdP) per the www.crediblemeds.org. "Known Risk of TdP" category
at the time of her Baseline Visit, which cannot be safely discontinued from the
Baseline Visit to the TOC Visit; or the participant is taking a strong cytochrome P450
enzyme 3A4 (CYP3A4) inhibitor.

- For any participant >=12 to <18 years of age, the participant has an abnormal ECG
reading.

- The participant has a QTc >450 msec or a QTc >480 msec for participants with
bundle-branch block.

- The participant has a documented or recent history of uncorrected hypokalemia within
the past 3 months.

- The participant has a known ALT value >2 times upper limit of normal (ULN).

- The participant has a known bilirubin value >1.5 times ULN (isolated bilirubin >1.5
times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35 percent
[%]).

- The participant has cirrhosis or current unstable liver or biliary disease per
investigator assessment defined by the presence of ascites, encephalopathy,
coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice.
