Age: 18 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Healthy adult males and/or females of non-childbearing potential, 18 to 55 years of age (inclusive) at the time of screening.
• Body mass index (BMI) ≥ 18.5 and ≤ 29.9 (kg/m2) and weight between 55.0 and 100.0 kg (inclusive).
• Medically healthy with clinically insignificant screening results (e.g., laboratory profiles, medical histories, electrocardiograms [ECGs], physical examination) as assessed by the PI.
• Voluntarily consent to participate in the study.
• 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:
• 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.
• Barrier method (diaphragm) for at least 14 days prior to Day 1 through 30 days following dosing of the study drug.
• Stable hormonal contraceptive for at least 3 months prior to Day 1 through 30 days following dosing of the study drug.
• Surgical sterilization (vasectomy) at least 6 months prior to Day 1.
• 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):
• Bilateral tubal ligation;
• Hysterectomy;
• Hysterectomy with unilateral or bilateral oophorectomy;
• Bilateral oophorectomy.

You may not qualify if…

• History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease.
• Positive urine drug/alcohol testing at screening or check-in (Day -1).
• Positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C antibodies (HCV).
• History or presence of alcoholism or drug abuse within the 2 years prior to Day 1.
• 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.
• 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.
• Use of any prescription medication (with the exception of hormone replacement therapy for females) within 14 days prior to Day 1.
• 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.
• Use of antacids, H2 receptor blockers or proton pump inhibitors within 7 days prior to Day 1.
• Documented hypersensitivity reaction or anaphylaxis to any medication
• Blood donation or significant blood loss (i.e., > 500 mL) within 56 days prior to Day
• Plasma donation within 7 days prior to Day 1.
• 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.
• Females who are pregnant or lactating.
• Surgery within the past three months prior to Day 1 determined by the PI to be clinically relevant.
• Any acute illness within 30 days prior to Day 1.
• QTcF interval >450 msec for males and >470 for females or history of prolonged QT syndrome at screening or check-in (Day -1).
• Calculated creatinine clearance less than 80 mL/min (Cockcroft-Gault method) at screening or check-in (Day -1).
• Subjects who have any clinically significant abnormalities on laboratory values at screening or check-in (Day -1), in particular:
• White blood cell count < 3,000/mm3, hemoglobin < 11g/dL.
• Absolute neutrophil count < 1,200/mm3 or platelet count < 120,000/mm3.
• 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).
• Any other condition or prior therapy, which, in the opinion of the PI, would make the subject unsuitable for this study.
