Interaction of Epanova on Warfarin Pharmacokinetic and Anticoagulant Activity and Comparison of the Effects of Epanova and Lovaza on Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) After Low-fat Meals
An Open-label, 2-cohort Study to Evaluate the Effect of Multiple Doses of Epanova® on the Single Dose Pharmacokinetics and Pharmacodynamics of Warfarin and to Compare the Systemic Exposure of Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) Following Multiple-dose Administrations of Epanova® Compared to Lovaza® in Healthy Normal Subjects
The primary objective of this study is to determine the effect of Epanova® on the pharmacokinetic and anticoagulant activity of warfarin.
The secondary objective of this study is to compare the systemic exposure of EPA and DHA following multiple-dose administration of Epanova®, a free fatty acid mixture, to Lovaza®, a mixture of fatty acid ethyl esters, under low-fat meal conditions since these products are likely to be administered to patients with cardiovascular disease who are recommended to consume low-fat meals.

Description
Inclusion Criteria:
Subject candidates must fulfill all of the following inclusion criteria to be eligible for participation in the study:
- Healthy adult male and/or females, 18 to 55 years of age (inclusive).
- Body mass index (BMI) ≥ 18 and ≤ 29.9 (kg/m2).
- Medically healthy with clinically insignificant screening results. Hemoglobin must be ≥ the lower limit of normal.
- Non-tobacco/nicotine-containing product users for a minimum of 6 months prior to dosing.
- Voluntarily consent to participate in the study and to follow the restrictions and procedures outlined for the study.
- For the Warfarin and Epanova Arm, females must be of non-childbearing potential defined as have undergone sterilization procedures at least 6 months prior to check-in or have been postmenopausal for at least 24 consecutive months prior to check-in of the study and have a screening follicle stimulating hormone level > 40 mIU/mL.
- For the Lovaza Arm, females may be of non-childbearing potential (as outlined above for Warfarin and Lovaza) or be of childbearing potential and must either be sexually inactive (abstinent) for 14 days prior to screening and remain so through 30 days following the final dosing of the study drug or until completion of the subject's first menstrual cycle following the final dosing of the study drug, whichever period of time is longer or have been using one of the acceptable methods of birth control.
Exclusion Criteria:
Subjects may be excluded from the study if there is evidence of any of the following criteria at screening, check-in, or at any time during the study as appropriate.

- Has a positive urine drug/alcohol testing at screening or check-in.
- Has a positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C antibodies (HCV).
- Has consumed fish within 7 days prior to check-in.
- Has used fish oil, other EPA and/or DHA containing supplements within 2 months of check-in.
- Has a history or presence of alcoholism or drug abuse within the 2 years prior to check-in.
- Has a known sensitivity or allergy to soybeans, fish, and/or shellfish.
- Has had a hypersensitivity or idiosyncratic reaction to compounds related to Epanova® and Lovaza®.
- Has used any prescription medication (with the exception of hormonal contraceptives for females in the Lovaza arm) within 14 days prior to check-in.
- Has used any over-the-counter (OTC) medication, including herbal products (e.g., bromelains, danshen, dong quai [Angelica sinesis], garlic, ginko biloba, ginseng, and St. John's wort), within the 7 days prior to check-in. Up to 2 g per day of acetaminophen is allowed at the discretion of the PI for the Lovaza arm.
- Has used any drugs known to significantly inhibit [strong or moderate] or induce liver enzymes involved in drug metabolism [CYP P450]) within 30 days prior to check-in.
- Has donated blood or has had a significant blood loss within 56 days prior to check-in.
- Has donated plasma within 7 days prior to check-in.
- Has participated in another clinical trial within 30 days prior to check-in.
- Is a female who is pregnant or lactating.
For Warfarin and Epanova Arm only:
- Has taken large daily doses of Vitamin K (exceeding 25 μg/day) or has eaten large quantities (e.g., averaging > 4 portions daily) of dark green/leafy vegetables (e.g., spinach, kale, collard greens, broccoli, Brussels sprouts) during the 2 months prior to check-in.
- Is employed or involved in any circumstance which would place them at increased risk of hemorrhage (e.g., contact sports, strenuous or unaccustomed weight lifting, running, bicycling).
- Has a personal or familial history of bleeding disorder(s), thromboembolic disease, clinical GI bleeding, or any history of GI surgery except uncomplicated appendectomy or cholecystectomy, or colorectal surgery for polyps, nonmalignant tumors, or diverticula.
