If of childbearing potential, must: i. Have a negative pregnancy test at the screening visit and on admission to the study site on Day-1. ii.

Male volunteers, must: 1. Agree not to donate sperm from signing the consent form until at least 90 days after the last dose of the study drug. 2. If engaging in sexual intercourse with a female partner who could become pregnant, agree to use adequate contraception (defined as use of a condom combined with their female partner's use of a highly effective method of contraception) from signing the consent form until at least 90 days after the last dose of the study drug. 3.

History or presence of CS cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal/bariatric modification, endocrine, immunologic, dermatologic, psychiatric, or neurological disease/disorder, including any acute illness, within the past 3 months determined by the PI to be clinically relevant. Note: Participants with history of resolved childhood asthma, psoriasis, atopic dermatitis, non-hospitalized depression, anxiety and/or migraine are permitted to be included in the study. 4.

History of risk factors for torsade de pointes (including a family history of long QT syndrome or sudden cardiac death) or a known arrythmia. 8. Presence or having sequelae of gastrointestinal, liver (including Gilbert's syndrome), kidney, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of drugs. 9. Liver function test results elevated \>1.5-fold above the ULN for gamma glutamyl transferase, bilirubin(total), ALP, AST or ALT. Volunteers with ALP and/or ALT/AST above the limits specified may be included, at the discretion of the PI (or delegate), if the levels are unaccompanied by clinical signs and are determined to be normal variants. 10. Estimated creatinine clearance \<60 mL/min using the Cockcroft-Gault formula or serum creatinine\>1.2-fold above the ULN. 11. A history of or positive test results for human immunodeficiency virus (HIV), hepatitis B surface antigen(HBsAg) or hepatitis C (HCV) at the screening visit. Note that a history of hepatitis C virus (HCV) is not exclusionary and if deemed cured by the PI, may be included on a case-by-case basis at the MM and Sponsor's discretion. 12. Positive drugs of abuse test, cotinine test or alcohol breath test results at the screening visit and/or on admission to the study site on Day -1. 13. Regular consumption of more than 10 standard alcoholic drinks/week and/or more than 4 standard alcoholic drinks on any one day, where 1 standard drink is 10 g of pure alcohol and is equivalent to 285 mL beer \[4.9% Alc/Vol\], 100 mL wine \[12% Alc/Vol\], or 30 mL spirit \[40% Alc/Vol\]). 14.
