• A body mass index (BMI) between 18.0 and 32.0 kg/m2, inclusive.
• In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital non-haemolytic hyperbilirubinemia [eg, suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at Screening and/or Check-in (Day -1) as assessed by the Investigator (or designee).
• Females will not be pregnant or lactating, and females of childbearing potential and males will agree to use contraception as detailed in Appendix 4.
• Able to comprehend and willing to sign an ICF and to abide by the study restrictions.

Exclusion Criteria

• Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, haematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the Investigator (or designee).
• History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the Investigator (or designee).
• History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed).
• Any of the following observed in at least 2 of 3 ECG measurements performed:
• QTcF > 450 msec.
• QRS duration > 110 msec.
• PR interval > 220 msec.
• findings which would make QTc measurements difficult or QTc data uninterpretable.
• Any history of additional risk factors for torsades de pointes (eg, heart failure, hypokalaemia, family history of long QT syndrome).
• Any history or current controlled or uncontrolled hypertension or systolic blood pressure > 140 mmHg or diastolic blood pressure > 90 mmHg confirmed by repeat measurement.
• History of alcoholism or drug/chemical abuse within 2 years prior to Check-in (Day -1).
• Alcohol consumption of > 21 units per week for males and > 14 units per week for females. One unit of alcohol equals ½ pint (285 mL) of beer or lager, 1 glass (125 mL) of wine, or 1/6 gill (25 mL) of spirits.
• Positive alcohol breath test result or positive urine drug screen (confirmed by repeat) at Screening or Check-in (Day -1).
• Positive hepatitis panel and/or positive human immunodeficiency virus test (Appendix 2).
• Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 90 days prior to dosing.
• Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including St. John's Wort, within 30 days prior to dosing, unless deemed acceptable by the Investigator (or designee).
• Use or intend to use any prescription medications/products other than hormone replacement therapy, oral, implantable, transdermal, injectable, or intrauterine contraceptives within 14 days prior to dosing, unless deemed acceptable by the Investigator (or designee).
• Use or intend to use slow release medications/products considered to still be active within 14 days prior to Check-in (Day -1), unless deemed acceptable by the Investigator (or designee).
• Use or intend to use any non-prescription medications/products including vitamins, minerals, and phytotherapeutic/herbal/plant-derived preparations within 7 days prior to Check-in (Day -1), unless deemed acceptable by the Investigator (or designee).
• Use of tobacco- or nicotine-containing products within 3 months prior to Check-in (Day -1) or positive cotinine at Screening or Check-in (Day -1).
• Ingestion of poppy seeds, Seville orange, or grapefruit-containing foods or beverages within 7 days prior to Check-in (Day -1).
• Subjects who are vegetarians, vegans, o
