Note: Appendectomy and hernia repairs are allowed. 2. The volunteer had a clinically significant illness within 8 weeks or a clinically significant infection within 4 weeks prior to the first dose. 3. The volunteer has evidence of a clinically significant deviation from normal in the physical examination, vital signs, or clinical laboratory determinations at screening or at Day -1 check-in (baseline). 4. The volunteer has systolic blood pressure \>140 mmHg oradiastolic blood pressure \>90mmHg. 5. The volunteer has a clinically significant ECG abnormality, including a marked baseline prolongation of QT/QTc interval (eg, repeated demonstration of a QTcF interval \>480msec), or hasa family history of prolonged QTc syndrome or sudden death. 6. The volunteer has a history of smoking or use of nicotine-containing substances within the previous 2 months, as determined by medical history or volunteer's verbal report and confirmed by cotinine test at check-in. 7. The volunteer has a history of drug or alcohol misuse within 6 months prior to screening or a positive urine drug test at screening or at check-in. 8. The volunteer has been diagnosed with acquired immune deficiency syndrome or has performed tests that are positive for human immunodeficiency virus (HIV), HepatitisBvirus (HBV), orHepatitis C virus (HCV). 9. The volunteer has participated in a clinical trial of other study drug before screening, and the time since the last use of other study drug is less than 5 times the half-life or 4 weeks, whichever is longer, or the volunteer is currently enrolled in another clinical trial.1 10. The volunteer has consumed grapefruit, starfruit, Seville oranges, or their products within 7 days prior to the first dose. 11. The volunteer has consumed herbal preparations/medications, including, but not limited to, St. John's Wort, kava, ephedra (ma huang), Ginkgo biloba, dehydroepiandrosterone, yohimbe, saw palmetto, and ginseng, within 7 days prior to the first dose (21days for St.John's Wort). 12. The volunteer has experienced a weight loss or gain of \>10% within 4 weeks prior to the first dose as noted by medical history and weight at screening and check-in. 13. The volunteer has received blood or blood products within 4 weeks, donated blood or blood products within 8 weeks prior to the first dose or donated double red cell within 16weeks prior to first dose. 14. The volunteer has used any over-the-counter (OTC) medications or prescription drugs (medications that can lower gastric acid in particular) within 2 weeks prior to the first dose. 15. The volunteer is allergic to any of the study drugs (or its excipients) to be given in this study. 16. A female participant is pregnant, lactating, or breastfeeding. 17. A male volunteer who plans to donate sperm or father a child within 30 days after receiving the study drug. 18. The volunteer has any condition that would make him or her, in the opinion of the PIor Sponsor, unsuitable for the study, or who, in the opinion of the PI, is not likely to complete the study for any reason.Note: One repeat of laboratory assessments, including vital signs and ECG,may be performed at screening and at -check-in(Day-1) at the discretion of the PI.
