5. Study Description
Brief Summary
This is a multi centre, two parallel arm, randomized, open-label, Phase 2a experimental study of oral Farnesoid X Receptor (FXR) modulator EYP001a to assess its safety and anti-viral effect when administered to non-treated (treatment naive or off treatment) chronic Hepatitis B (CHB) patients in combination with entecavir (ETV) and pegylated interferon alpha2a (peg-IFN). An experimental treatment period of 16 weeks will be followed by a 24 week maintenance period with ETV standard of care (SoC).
Detailed Description
In total 30 eligible patients will be enrolled and randomized at approximately 7 study sites.
Patients will be randomized prior to study drug (EYP001a, ETV and peg-IFN) administration on Day 1 in the ratio of 1:1 into 2 treatment arms:
Arm 1: EYP001a QD + ETV 0.5 mg QD + peg-IFN dosed per body surface area (180 µg, 135 µg or 90 µg) QW (± 3 days) (15 patients)
Arm 2: EYP001a QD + peg-IFN dosed per body surface area (180 µg, 135 µg or 90 µg) QW (± 3 days) (15 patients)
Patients enrolled in the study will be assessed as outpatients. Patient screening will occur no more than 37 days prior to the Day 1 visit. Eligible patients will undergo further assessments on Day 1 to qualify for study drug administration on Day 1.
The visits during the study are planned as below:
Screening visit: 5 weeks (37 days)
16 weeks treatment period
24 weeks maintenance period. During maintenance period patients are kept on ETV until the end of the trial at Week 40.
