Criteria

Inclusion Criteria:

1. The subject is a male or female 18 to 55 years of age, inclusive.

2. The subject has a body mass index 18 to 32 kg/m2, inclusive, and a total body weight ≥50 kg, inclusive, at screening.

3. The subject is considered by the investigator to be in good general health as determined by medical history, clinical laboratory test results, vital sign measurements, 12-lead ECG results, and physical examination findings at screening.

4. Female subjects of childbearing potential must be non-pregnant and non-lactating and must use one of the methods of contraception listed below for the duration of the treatment until at least 28 days after the last dose of the study drug, or be surgically sterile (ie, hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), or postmenopausal (defined as amenorrhea 12 consecutive months and documented plasma follicle stimulating hormone level >40 IU/mL). Female subjects must have a negative pregnancy test at screening and before the first dose of study drug.

Highly effective methods of contraception are those that result in a failure rate of less than 1% per year when used consistently. Examples are provided below:

1. Implant contraceptive (eg, Jadelle®)

2. Intrauterine device containing either copper or levonorgestrel (eg, Mirena®)

3. Male sterilization with absence of sperm in the post-vasectomy ejaculate

OR an effective method that result in a failure rate of less than 5% to 10% per year. Examples are provided below:

4. Injectable contraceptive (eg, Depo Provera)

5. Oral contraceptive pill (combined hormonal contraceptive pill or progestogen-only 'mini-pill')

6. Vaginal contraceptive ring (eg, NuvaRing®)

Female subjects must also agree not to donate eggs, from dosing until at least 28 days after the last dose of study drug.

A male subject and his female partner who is of childbearing potential must agree to use one of the methods of contraception listed above for the duration of the treatment until at least 28 days after the last dose of the study drug. A male subject must also agree not to donate sperm, for the duration of the treatment until at least 28 days after the last dose of the study drug.

5. The subject agrees to comply with all protocol requirements.

6. The subject is able to provide written informed consent.

Exclusion Criteria:

1. The subject has current evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).

2. The subject has any condition possibly affecting drug absorption (eg, gastrectomy).

3. The subject has a history of cancer with the exception of adequately treated basal cell or squamous cell carcinoma of the skin.

4. The subject has supine blood pressure (BP) >140 mm Hg (systolic) or >90 mm Hg (diastolic), following at least 5 minutes of supine rest. If BP is >140 mm Hg (systolic) or >90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the subject's eligibility at screening.

5. The subject has 12-lead ECG demonstrating corrected QT interval by Fridericia (QTcF) >450 msec, or a QRS interval >120 msec at screening. If QTcF exceeds 450 msec, or QRS interval exceeds 120 msec, the ECG should be repeated 2 more times and the average of the 3 QTcF (or QRS interval) values should be used to determine the subject's eligibility.

6. The subject has ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat, if deemed necessary:

1. Serum creatinine level above the upper limit of normal (ULN) or an estimated glomerular filtration rate value <80 mL/min/1.73 m2 calculated with the Chronic Kidney Disease Epidemiology Collaboration formula and the absence of protein in urine, at screening.

2. Aspartate aminotransferase or alanine aminotransferase values more than >1.5 × ULN.

3. Fasting glucose >110 mg/dL (6.1 mmol/L).

4. Total bilirubin >1.5 × ULN.

5. Hematological values outside the normal reference range for local laboratory results.

6. Positive fecal occult blood test at screening or at check-in (Day -1).

7. The subject has any medical history of disease that has the potential to cause a rise in total bilirubin over the ULN. Subjects with borderline clinical laboratory values outside the reference range may be included in the study if the investigator deems that the values are not clinically significant.

Note: Subjects with a history of Gilbert's syndrome may have a direct bilirubin measured and would be eligible for this study provided the direct bilirubin is8. The subject has a history of any lymphoproliferative disorder (such as Epstein Barr Virus related lymphoproliferative disorder, as reported in some subjects on immunosuppressive drugs), history of lymphoma, leukemia, myeloproliferative disorders, multiple myeloma, or signs and symptoms suggestive of current lymphatic disease.

9. The subject has a history of relevant drug and/or food allergies (ie, allergy to any study drug or excipients, or any significant food allergy that could preclude a standard diet in the clinical unit).

10. The subject has a clinically significant infection currently or within 6 months of first dose of study drug (eg, those requiring hospitalization or parenteral antimicrobial therapy or opportunistic infections within the last 6 months), or a history of chronic or recurrent infectious disease.

11. The subject has other severe acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.

12. The subject has or has had symptomatic herpes zoster or herpes simplex within 12 weeks, more than one episode of local herpes zoster, or a history (single episode) of disseminated zoster.

13. The subject has a positive test result for hepatitis B surface antigen, hepatitis C virus antibody, or human immunodeficiency virus types 1 or 2 antibodies at screening.

16. The subject is unwilling or unable to comply with the lifestyle restrictions described in this protocol.

17. The subject is a smoker or has used nicotine or nicotine-containing products (eg, snuff, nicotine patch, nicotine chewing gum, mock cigarettes, or inhalers) within 6 months before the first dose of study drug.

18. The subject has a positive test result for drugs of abuse, or cotinine (indicating active current smoking) at screening or before the first dose of study drug.

19. The subject has used any prescription or over the counter medications (except paracetamol [up to 2 g per day]), including herbal supplements, within 14 days before the first dose of study drug. Nutritional supplements are allowed if unlikely to interfere with the study results and agreed by medical monitor and investigator.

23. The subject has undergone significant trauma or major surgery within 4 weeks of screening.

25. The subject has a first-degree relative with a hereditary immunodeficiency.

26.

27. The subject has a history of alcohol abuse or drug addiction within the last year or excessive alcohol consumption (regular alcohol intake >21 units per week for male subjects and >14 units of alcohol per week for female subjects) (1 unit is equal to approximately ½ pint [200 mL] of beer, 1 small glass [100 mL] of wine, or 1 measure [25 mL] of spirits) or use of alcohol 48 hours before the first dose of study drug.
