INCLUSION CRITERIA

  1. Males or females aged 18 - 50 years inclusive
  2. Able and willing to provide signed informed consent to participate in this study

  2. Family or personal history of congenital long QT syndrome
  3. Participated in another clinical trial of an investigational drug (or medical device) within 30 days or 5-half-lives, whichever is longer, prior to Screening, or is currently participating in another trial of an investigational drug (or medical device)
  4. Clinically significant medical disease that is likely, in the Investigator's opinion, to significantly impact the study's efficacy and safety assessments (e.g., history significant cardio-pulmonary disease or arrhythmias) within 6 months of Screening.
