Brief summary

This study will evaluate the bioequivalence of 105 mg fenofibric acid tablets relative to 145 mg fenofibrate tablets in healthy volunteers under fasting conditions. A secondary objective is to characterize the pharmacokinetic profile of fenofibric acid when administered as a single 105 mg dose to healthy volunteers in a fasted state. Safety and tolerability of this regimen will also be evaluated.

Detailed description

Fenofibrate is rapidly and completely hydrolyzed to fenofibric acid, the active moiety. The primary objective of this study is to evaluate the bioequivalence of fenofibric acid and fenofibrate under fasting conditions. Additionally, the safety and tolerability of the study treatments will be evaluated. Fifty-four healthy, non-smoking, non-obese, 18-45 year old, male and female volunteers will be randomly assigned in a crossover fashion to receive each of two dosing regimens, fenofibric acid (Fibricor™) and fenofibrate (Tricor®) in sequence with a 7 day washout period between dosing periods. On the morning of Day 1, after an overnight fast of at least 10 hours, subjects will receive either a single oral dose of the test formulation, fenofibric acid (1 x 105 mg tablet) or a single oral dose of the reference formulation, fenofibrate (1 x 145 mg tablet). After a 7 day washout period, on the morning of Day 8 after an overnight fast, subjects will receive the alternate regimen. Fasting will continue for 4 hours after each dose. Blood samples will be drawn from all participants before dosing and for 72 hours post dose at times sufficient to adequately define the pharmacokinetics of fenofibric acid and fenofibrate. Subjects will be monitored throughout their participation for adverse reactions to the study drug and/or procedures. Seated blood pressure and pulse will be measured prior to each dose and approximately 2 hours post-dose. All adverse experiences, whether elicited by query, spontaneously reported, or observed by clinic staff, will be documented in the subject's case report form.
