  • People whose heart tracing (ECG) at screening shows a QTcF interval of 450 milliseconds or more (a measurement related to the heart's electrical activity) (confirm with trial site).
  • People whose ECG shows abnormalities that, in the investigator's judgement, could increase the risk of a serious heart rhythm problem.
