8. Positive testing for HIV Ab, HBsAg or HCV Ab.

9.Positive urine drug or alcohol testing at screening or check-in (Day -1).

10.Use of prescription medications (with the exception of hormone replacement therapy and contraceptives), including nonsteroidal anti-inflammatory drugs, sucralfate, or herbal preparations within 7 days before Check in (Day -1), or use of an over-the-counter medication, acetaminophen (>2 g/day), vitamins, or supplements (including fish liver oils) within 7 days before Check in (Day -1); or probenecid or valproic acid within 30 days before Check in (Day -1).

11. Receipt of an investigational drug within 30 days or 5 half-lives prior to the first administration of study drug, whichever is longer.

12. Known history of clinically significant hypersensitivity reaction or anaphylaxis to any medication, or history of clinically significant hypersensitivity to the study drug or any related drugs or to any of the excipients, or significant food intolerance.

13. Donation of blood or plasma within 30 days prior to dosing, or loss of whole blood of more than 500 mL within 30 days prior to dosing, or receipt of a blood transfusion within 1 year of study enrollment.

14. Any other condition or prior therapy, which, in the opinion of the Investigator, would make the volunteer unsuitable for this study, including inability to cooperate fully with the requirements of the study protocol or likely to be non-compliant with any study requirements.
