5. Willing and able to abstain from drug, alcohol, and tobacco use during study participation.

Exclusion criteria

1. Medical history and/or findings on physical examination indicating the presence of clinically significant illness.
2. Clinically significant abnormalities of vital signs or clinical laboratory results (including hematology, chemistry, and urinalysis).
3. Presence or recent history (within 28 days prior to Screening) of active and clinically significant (as judged by the Investigator) gastrointestinal, renal, cardiovascular, hepatic, metabolic, allergic, dermatologic, hematologic, pulmonary, neurological or psychiatric illness or disorder.
4. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs.
5. Clinically significant ECG abnormalities including QTc ≥ 450 msec.
6. Use of any tobacco-containing or nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patches, nicotine lozenges, or nicotine gum) within 6 months prior to Screening.
7. Use of any prescription, illegal, or investigational drug within 28 days prior to Day 1.

11. Positive urine drug screen, urine cotinine test, or alcohol breath test at Screening or check-in to the clinical study unit (CSU). Subjects with results believed to be false positives can be allowed to screen while results are retested at a specialized laboratory.
12. Positive serology for the surface antigen of Hepatitis B (HBsAg), Hepatitis C (anti HCV), or human immunodeficiency virus (HIV) antibody screen.
13. Donation of blood or plasma to a blood bank or for a clinical study (except for study screening) within 28 days prior to Day 1.
14. Receipt of blood products within 2 months prior to Screening.
15. Any condition or other reason that, in the opinion of the Investigator, would render the subject unsuitable for the clinical study.
