* Acceptable medical history, physical examination, ECG, laboratory investigations per the Investigator.
* Female subjects must meet at least one of the following requirements:

  * Agree to abstain from sexual intercourse from screening, throughout the duration of the study and for at least 90 days after the last study drug administration.
  * Have used and agree to continue to use a reliable method of contraception (e.g., hormonal contraceptives, condom with spermicide, IUD) for at least 30 days before initial dosing, throughout the duration of the study and for at least 90 days after the last study drug administration.
  * Surgically sterile (bilateral oophorectomy or hysterectomy, bilateral tubal ligation at least 3 months before initial dosing or Essure® device placement).

* Significant history or current evidence of risk factors for Torsade de Pointes (TdP).
* History of Gilbert syndrome.
* Having poor vein access.
