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
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.

|Official Title:||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|
- Pharmacokinetics of R- and S- warfarin [ Time Frame: 168 hours ]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 [ Time Frame: 168 hours ]The INRmax over 168 hours postdose and INR AUC0-168 when warfarin is administered with and without Epanova®.
- Total EPA+DHA [ Time Frame: 24 hours ]The AUC0-tau and Cmax of baseline-adjusted total EPA+DHA following multiple doses (14 days) of Epanova® and Lovaza®.
