This is an interventional treatment trial for Hepatitis B, Chronic Read More

Inclusion Criteria:

1. Has given voluntary written informed consent before performance of any study related procedure

4. Age: 18-65 years, inclusive, at screening
5. Body mass index (BMI): 17.0-35.0 kg/m2 inclusive, at screening
6. Weight: >60 kg for males and >45 kg for females
7. Has clinical chemistry, hematology, coagulation and urinalysis tests within normal, allowable limits (with the exception of alanine aminotransferase (ALAT) [see inclusion criterion #10]); if there is an out of range value, it must be considered clinically insignificant in order to be eligible
8. Has normal vital signs after at least 5 minutes resting in supine position at screening: 95 mm Hg < systolic blood pressure < 140 mm Hg; 45 mm Hg < diastolic blood pressure < 90 mm Hg; 40 bpm < heart rate < 90 bpm
9. Has no clinically significant abnormal 12-lead automatic electrocardiogram (ECG) (incomplete right bundle branch block can be accepted) at screening: 120 ms < PR-interval < 210 ms, QRS-duration < 120 ms, corrected QT interval (QTc) (Fridericia's) ≤ 450 msec for males and females
10. Has ALAT ≤ 3 x upper limit of normal (ULN) at screening
11. Has documented liver histology with Metavir score (F0, F1, F2 or F3) or liver fibrosis documented with non-invasive alternatives to liver biopsy (Fibroscan) or shear wave elastography (Aixplorer) value < 14.6 kPa
12. Agrees to abstain from all medication, including non-prescription and prescription medication (including vitamins and natural or herbal remedies, e.g. St. John's Wort) for 28 days prior to (each) admission to the clinical research center until discharge, except for authorized medications such as hormonal contraceptives for females (registered in The Netherlands) and paracetamol. On a case-by-case basis, regular co-medication either as defined on the separate medication exception list or as documented by written approval from the Sponsor and the PI as acceptable prior to randomization, will not be considered as a deviation from this criterion. All other situations related to co-medications are considered as deviations
13. At screening, females must be non-pregnant and non-lactating, or of non-childbearing potential (either surgically sterilized or physiologically incapable of becoming pregnant, or at least 1 year postmenopausal [amenorrhoea duration of 12 consecutive months); non-pregnancy will be confirmed for all females by a serum pregnancy test conducted at screening and at (each) admission to the clinical research center
14. Female subjects of child-bearing potential, with a fertile male sexual partner, should be willing to use adequate contraception from screening until 90 days after the followup visit. Adequate contraception is defined as using hormonal contraceptives or an intrauterine device combined with at least 1 of the following forms of contraception: a diaphragm or cervical cap, or a condom. Also, total abstinence, in accordance with the lifestyle of the subject, is acceptable
15. Male subjects, if not surgically sterilized, should be willing to use adequate contraception and not donate sperm from (first) admission to the clinical research center until 90 days after the follow-up visit. Adequate contraception for the male subject (and his female partner) is defined as using hormonal contraceptives or an intrauterine device combined with at least 1 of the following forms of contraception: a diaphragm or cervical cap, or a condom. Also, total abstinence, in accordance with the lifestyle of the subject is acceptable
16. At screening, has no recent (<3 months) history of any clinically significant conditions, which, in the opinion of the PI, would jeopardize the safety of the subject or impact the validity of the study results
17. Willingness to abstain from alcohol and methylxanthine-containing beverages or food (coffee, tea, cola, chocolate, energy drinks) from 48 hours prior to (each) admission to the clinical research center

Exclusion Criteria:

1. Previous participation in the current study
