Drug Drug Interaction Study for EYP001 With Entecavir

Study of the Drug Interaction of EYP001a With Entecavir in Healthy Subjects

This is a Phase 1, single-center, open-label, three subsequent dosing periods study to evaluate the drug-drug-interaction (DDI), pharmaco-kinetics (PK) and pharmacodynamics (PD), safety, and tolerability of a single dose of EYP100a combined with ETV in healthy men and women dosed in the morning under fasted conditions.

Study Overview

• Status: Completed
• Conditions: Hepatitis B, Chronic
• Intervention / Treatment: Drug: EYP001; Drug: Entecavir 1 MG

Detailed Description

This is a Phase 1, single-center, open-label, three consecutive dosing periods study to evaluate the drug-drug interaction, PK, safety, tolerability and PD of a single dose of EYP100a combined with ETV in healthy men and women. Sixteen (16) adult male and female healthy participants 18 to 60 years of age inclusive are planned to participate in the study. Women of childbearing potential will be eligible to participate if she is non pregnant or non lactating and willing to use adequate contraception.

All participants in the study will be monitored for safety after administration of the last dose of investigational product and with a follow up visit. The DDI, PK, PD, safety and tolerability of EYP001a and ETV will be assessed based on plasma-concentration profiles of EYP001a and ETV, FXR related PD markers and the types and frequency of treatment-emergent adverse events (TEAEs) reported, concomitant medication usage, and changes from baseline in physical examination (PE), vital signs, electrocardiogram (ECG), and standard clinical laboratory tests.

• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Subject has provided written consent
• In the investigator's opinion, the subject is able to understand and comply with protocol requirements, instructions, and study restrictions and is likely to complete the study as planned
• Subject is in good health as deemed by the investigator, based on the findings following a medical evaluation, including medical history, physical examination, laboratory tests and single ECG
• Male or female, 18-60 years of age inclusive
• Body mass index 18.0-35.0 kg/m2, inclusive. The minimum weight is 50 kg, the maximum is 115 kg.

• A female subject is eligible to participate in this study if:

  1. She is of non-childbearing potential (defined as females with a documented tubal ligation, bilateral oophorectomy or hysterectomy) or postmenopausal (defined as 12 months of spontaneous amenorrhea and follicle stimulating hormone level within the laboratory's reference range for postmenopausal females). A post-menopausal female receiving hormone replacement therapy (HRT) other than hormone replacement patches who is willing to discontinue hormone therapy 28 days before study drug dosing and agrees to remain off hormone replacement therapy for the duration of the study may be eligible for study participation. A post menopausal female using Hormone Replacement patches who is willing to discontinue the patch 48 hours before Check in on Day -1 and until the completion of her End of Study visit is eligible for study participation
  2. She is of childbearing potential and is non pregnant or non lactating and willing to use adequate contraception from screening until 6 months after the End of Study visit. Adequate contraception is defined as a progesterone only intra uterine 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 participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception
  3. She is of childbearing potential and is non pregnant or non lactating and taking the combined oral contraceptive pill and willing to discontinue the combined oral contraceptive pill 7 days prior to check in on Day -1 and until the completion of her End of Study visit and use adequate contraception from the day of cessation. Adequate contraception is defined as a diaphragm or cervical cap together with a condom. Also, total abstinence in accordance with the lifestyle of the participant is acceptable. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
• If male, subject is surgically sterile or practicing required forms of birth control until 6 months after the last dose of the study drug(s). Males must agree to refrain from sperm donation from check-in through 6 months after the last dose of the study drug(s)
• Subject does not use nicotine or nicotine-containing products during study participation.

Exclusion Criteria:

• Subject is mentally or legally incapacitated, has significant emotional problems at the time of prestudy (screening) visit or expected during the conduct of the study or has a history of a clinically significant psychiatric disorder over the last 5 years.
• Subject has a history of any illness that, in the opinion of the investigator, would confound the objectives or results of the study or poses an additional risk to the subject by their participation in the study
• Subject has an estimated creatinine clearance of ≤ 80 mL/min based on the Cockcroft-Gault equation; subjects who have an actual or estimated creatinine clearance within 10% of 80 mL/min may be enrolled in the study at the discretion of the investigator.
• Pregnant or nursing (lactating) females, confirmed by a positive human chorionic gonadotropin laboratory test or females contemplating pregnancy. Men whose female partners are pregnant or contemplating pregnancy from the date of screening until 6 months after their last dose of study drugs
