4. Body temperature (tympanic or oral) in the range 35.5°C to 37.5°C (inclusive).
5. No clinically significant findings in serum chemistry, hematology, coagulation and urinalysis tests as judged by the Investigator. Note: for SAD Cohort 6, ALT, AST, ALP and gamma-glutamyl transferase (GGT) must be normal (within the reference range).
6. Triplicate 12-lead ECG (taken after the volunteer has been supine for at least 5 minutes) with a QTcF = 450 msec for males and = 470 msec for females and no clinically significant abnormalities.
5. Be nonsmokers (including tobacco, nicotine replacement therapy, e-cigarettes and marijuana) for at least 3 months prior to first study drug administration (self-reported to the Investigator) at screening visit, Day -4 (SAD Cohort 6 only) and at check-in on Day -1.
6. Female volunteers must:
1. Be of nonchildbearing potential i.e., surgically sterilized (hysterectomy, bilateral salpingectomy, bilateral oophorectomy at least 6 weeks before screening) or postmenopausal (where postmenopausal is defined as no menses for 12 months without an alternative medical cause, and a follicle-stimulating hormone (FSH) level >40 IU/L at the screening visit), or
2. If of childbearing potential, must agree not to donate ova, not to attempt to become pregnant and, if engaging in sexual intercourse with a male partner, must agree to use an acceptable method of contraception from one month prior to screening until at least 30 days after the last dose of study drug.
7. Male volunteers must agree not to donate sperm and, if engaging in sexual intercourse with a female partner who could become pregnant, must agree to use an acceptable method of contraception from signing the consent form until at least 90 days after the last dose of study drug.
8. Have suitable venous access for blood sampling.
9. Be willing and able to comply with all study assessments and adhere to the protocol schedule and restrictions.

Key exclusion criteria
1. History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic or neurological disease, including any acute illness or major surgery within the past 3 months determined by the PI to be clinically significant.
2. Acute infections or infestations within 4 weeks prior to dosing or current infection that requires systemically absorbed antibiotic, antifungal, antiparasitic or antiviral medications.
3. Presence or history of any abnormality or illness, including gastrointestinal surgery, which in the opinion of the PI may affect absorption, distribution, metabolism or elimination of the study drug.
4. Any history of malignant disease in the last 5 years (excludes surgically resected skin squamous cell or basal cell carcinoma).
5. Any screening laboratory result outside the normal laboratory reference range (as confirmed upon repeated testing) and deemed clinically significant by the PI.

6. Presence of clinically relevant immunosuppression from, but not limited to, immunodeficiency conditions such as common variable hypogammaglobulinemia.
7. Use of or plans to use systemic immunosuppressive (e.g., corticosteroids by any route, methotrexate, azathioprine, cyclosporine) or immunomodulating medications (e.g., interferon) within 5 half-lives of individual agent or within 28 days (whichever is longer) prior to dosing or during the study.
8. Use of or plans to use agents (e.g., grapefruit and grapefruit products) that have clinically significant interaction with CYP3A4 or the use of any medications that could have a significantly impact on organ function (e.g., barbiturates, omeprazole, cimetidine) during the study or within 5 half-lives of individual agent or within 28 days (whichever is longer) prior to dosing.
