Eligibility
Key inclusion criteria
1. Healthy adult males and/or females of non-childbearing potential, 18 to 55 years of age (inclusive) at the time of screening.
2. Body mass index (BMI) = 18.5 and = 29.9 (kg/m2) and weight between 55.0 and 100.0 kg (inclusive).
3. Medically healthy with clinically insignificant screening results (e.g., laboratory profiles, medical histories, electrocardiograms [ECGs], physical examination) as assessed by the PI.
4. Voluntarily consent to participate in the study.
5. Male volunteers must agree to use a condom when engaging in any sexual activity from study check-in through 30 days following the last administration of the study drug, and to not donate sperm during this same period of time. If engaging in sexual activity with a female partner of childbearing potential, an additional method of birth control must be used. Approved additional methods of birth control include:

1. Intra-uterine device (IUD) in place for at least 3 months prior to Day 1 through 30 days following the final dosing of the study drug.
2. Barrier method (diaphragm) for at least 14 days prior to Day 1 through 30 days following dosing of the study drug.
3. Stable hormonal contraceptive for at least 3 months prior to Day 1 through 30 days following dosing of the study drug.
4. Surgical sterilization (vasectomy) at least 6 months prior to Day 1.
6. Females of non-childbearing potential with serum FSH levels = 40 mIU/mL are either postmenopausal (defined as 12 months spontaneous amenorrhea) or have undergone one of the following sterilization procedures at least 6 months prior to Day 1 (and is documented):

1. Bilateral tubal ligation;
2. Hysterectomy;
3. Hysterectomy with unilateral or bilateral oophorectomy;
4. Bilateral oophorectomy.
Minimum age
18 Years
Maximum age
55 Years
Sex

Can healthy volunteers participate?
Yes
Key exclusion criteria
1. History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease.
2. Positive urine drug/alcohol testing at screening or check-in (Day -1).
3. Positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C antibodies (HCV).
4. History or presence of alcoholism or drug abuse within the 2 years prior to Day 1.
5. Use of more than 5 packs/week of cigarettes (or equivalent amount of nicotine-containing product) within 6 months prior to Day 1. Subjects must agree to refrain from smoking for the duration of the study.
6. Excessive intake of alcohol, defined as an average daily intake of greater than 2 standard drinks for women and 4 standard drinks for men; 1 bottle of beer (375mL) is equivalent to approximately 1.4 standard drinks, 1 glass of spirits (30mL) is equivalent to approximately 1 standard drink and 1 glass (150mL) of wine is equivalent to approximately 1.5 standard drinks.
7. Use of any prescription medication (with the exception of hormone replacement therapy for females) within 14 days prior to Day 1.
8. Use of any over the counter (OTC) medication, including herbal products, probiotics and vitamins, within the 7 days prior to Day 1. Up to 2 grams per day of paracetamol is allowed for acute events at the discretion of the PI.
9. Use of antacids, H2 receptor blockers or proton pump inhibitors within 7 days prior to Day 1.
10. Documented hypersensitivity reaction or anaphylaxis to any medication
11. Blood donation or significant blood loss (i.e., > 500 mL) within 56 days prior to Day
12. Plasma donation within 7 days prior to Day 1.
13. Participation in another investigational clinical trial within 30 days prior to Day 1 or within 5 half-lives of the previous investigational drug, whichever is longer.
14. Females who are pregnant or lactating.
15. Surgery within the past three months prior to Day 1 determined by the PI to be clinically relevant.
16. Any acute illness within 30 days prior to Day 1.
17. QTcF interval >450 msec for males and >470 for females or history of prolonged QT syndrome at screening or check-in (Day -1).
18. Calculated creatinine clearance less than 80 mL/min (Cockcroft-Gault method) at screening or check-in (Day -1).
19. Subjects who have any clinically significant abnormalities on laboratory values at screening or check-in (Day -1), in particular:

1. White blood cell count < 3,000/mm3, hemoglobin < 11g/dL.
2. Absolute neutrophil count < 1,200/mm3 or platelet count < 120,000/mm3.
3. Liver function abnormalities at screening or check-in (Day -1) (defined by an elevation in bilirubin, AST or ALT 1.5 x ULN of the normal range for subjects based on age and sex).
20. Any other condition or prior therapy, which, in the opinion of the PI, would make the subject unsuitable for this study.
