Study Description
Brief Summary:

The farnesoid X receptor (FXR) regulates hepatitis B virus replication through the bile acids pathway. EYP001a is a selective, synthetic FXR agonist under development for the treatment of hepatitis B.

This Phase 1 study is designed primarily to assess Pharmacokinetics (PK) under fed and fasted conditions, and to assess the safety, tolerability and Pharmacodynamics (PD) of single oral doses of EYP001a in subjects with chronic HBV infection.


Condition or disease Intervention/treatment Phase
Hepatitis B, Chronic Drug: EYP001a Phase 1

Detailed Description:

This is a single-center, open-label, randomized, 4-way crossover study.

A total of 14 chronic HBV subjects will participate. Subjects will receive 4 single dose administrations of EYP001a during the study. There will be 2 separate dosing periods: 1 period with 2 single administrations of EYP001a in the morning, once under fasted conditions and once under fed condition (separated by 48.5 hours), and 1 period with 2 single administrations of EYP001a in the evening, once under fasted conditions and once under fed condition (separated by 48.5 hours).

The subjects will be randomized to 1 of 4 treatment sequences:

  • Sequence 1: Period 1 first dose morning fasted, second dose morning fed; Period 2 first dose evening fasted, second dose evening fed.
  • Sequence 2: Period 1 first dose evening fasted, second dose evening fed; Period 2 first dose morning fasted, second dose morning fed.
  • Sequence 3: Period 1 first dose morning fed, second dose morning fasted; Period 2 first dose evening fed, second dose evening fasted.
  • Sequence 4: Period 1 first dose evening fed, second dose evening fasted; Period 2 first dose morning fed, second dose morning fasted.

Participation will include an eligibility screening period of maximally 40 days, clinic stay during the treatment periods, and a followup visit 4 to 6 days after the last study drug administration.

The safety and tolerability of EYP001a will be assessed by evaluating vital signs, ECGs, liver ultrasound, clinical laboratory and adverse events.

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

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
