Eligibility criteria: Inclusion Criteria

* Chinese healthy male and female subjects, 18 to 60 years of age, inclusive.
* A Body Mass Index (BMI) of between 19 to 27 kg/m2 inclusive, and a body weight of at least 45 kg.
* Women should be of non-childbearing potential. Female subjects must be either surgically sterile (by means of hysterectomy and/or bilateral oophorectomy) or post-menopausal for at least one year (defined as amenorrhea \>/=12 consecutive months without another cause, and confirmed by follicle stimulating hormone level \>35 mIU/mL).
* For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm

Exclusion Criteria

* Pregnant (positive pregnancy test) or lactating women, and male subjects with partners who are pregnant or lactating.
* History or symptoms of any clinically significant gastrointestinal, renal, hepatic, broncho-pulmonary, neurological, psychiatric, cardio-vascular, endocrinological, hematological or allergic disease, metabolic disorder, cancer or cirrhosis.
* Personal history of congenital long QT syndrome or family history of sudden death.
* History of Gilbert's syndrome.
* History of having received or currently receiving any systemic anti-neoplastic (including radiation) or immune-modulatory treatment (including systemic oral or inhaled corticosteroids) \</=6 months prior to the first dose of study drug or the expectation that such treatment will be needed at any time during the study.
* Subjects who have had significant acute infection, e.g., influenza, local infection, acute gastrointestinal symptoms or any other clinically significant illness within two weeks of dose administration.
* Any confirmed significant allergic reactions (urticaria or anaphylaxis) against any drug, or multiple drug allergies (non-active hay fever is acceptable).
* Electrocardiogram (ECG) with QRS and/or T-wave judged to be unfavorable for a consistently accurate QT measurement (e.g., neuromuscular artifact that cannot be readily eliminated, arrhythmias, indistinct QTS onset, low amplitude T-wave, merged T- and U waves, prominent U-waves)
* Creatinine clearance (CrCl) \</=70 mL/min (using the Cockcroft-Gault formula)
* Positive test at screening of any of the following: hepatitis A (HAV IgM Ab), hepatitis B (HBsAg), hepatitis C (HCV RNA or HCV Ab) or human immunodeficiency virus 1 and 2 (HIV Ab).
* Participation in an investigational drug or device study within 90 days prior to screening or more than 4 times per year.
* Donation or loss of blood over 500 mL within 3 months prior to screening.
* Any suspicion or history of drug and/or alcohol abuse within the last year.
* History (within 3 months of screening) of alcohol consumption exceeding two standard drinks per day on average (1 standard drink = 10 grams of alcohol). Alcohol consumption will be prohibited at least 48 hours before screening, 48 hours before and 48 hours after each dose, and 48 hours before each scheduled visit.
* Use of \>5 cigarettes or equivalent nicotine-containing product per day.
* Taking any prescribed or over-the-counter medications (including vitamins or herbal remedies) within 2 weeks of first dosing or within 5 times the elimination half-life of the medication prior to first dosing (whichever is longer). Occasional acetaminophen/paracetamol is allowed.
* Subjects under judicial supervision, guardianship or curatorship.
