Eligibility Criteria

18 Years - 55 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

Subject candidates must fulfill all of the following inclusion criteria to be eligible for participation in the study:

  1. Healthy adult male and/or females, 18 to 55 years of age (inclusive).
  2. Body mass index (BMI) ≥ 18 and ≤ 29.9 (kg/m2).
  3. Medically healthy with clinically insignificant screening results. Hemoglobin must be ≥ the lower limit of normal.
  4. Non-tobacco/nicotine-containing product users for a minimum of 6 months prior to dosing.
  5. Voluntarily consent to participate in the study and to follow the restrictions and procedures outlined for the study.
  6. 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.
  7. 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.

Up to 2 g per day of acetaminophen is allowed at the discretion of the PI for the Lovaza arm.
  11. 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.
  12. Has donated blood or has had a significant blood loss within 56 days prior to check-in.
  13. Has donated plasma within 7 days prior to check-in.
  14. Has participated in another clinical trial within 30 days prior to check-in.
  15. Is a female who is pregnant or lactating.

For Warfarin and Epanova Arm only:

  1. 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.
  2. 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).
  3. 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.
  4. Has active severe gingivitis.
  5. Has had a hypersensitivity or idiosyncratic reaction to compounds related to warfarin.
  6. Has a recent physical injury (within the 2 weeks prior to screening).

  8. Is allergic to Vitamin K.
  9. Has used non-steroidal anti-inflammatory (NSAID) drugs within the 2 weeks prior to check-in.

Outcomes

Primary Outcome Measures

Pharmacokinetics of R- and S- warfarin
The primary endpoints of this study will be the area under the curve (AUC)0-t, AUC0-inf, and maximum concentration (Cmax) of R- and S warfarin and the maximum International Normalized Ratio (INRmax) over 168 hours postdose and INR AUC0-168 when warfarin is administered with and without Epanova®.
Pharmacodynamics of R- and S- warfarin
The INRmax over 168 hours postdose and INR AUC0-168 when warfarin is administered with and without Epanova®.

Secondary Outcome Measures

Total EPA+DHA
The AUC0-tau and Cmax of baseline-adjusted total EPA+DHA following multiple doses (14 days) of Epanova® and Lovaza®.

5. Study Description

Brief Summary
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.
