Brief summary

This was a 24-month, open-label extension study that followed an 8-week double-blind study (Study LOV111859/OM5) and an 8-week, open-label extension study (LOV111860/OM5X). Study LOV111859/OM5 was conducted to evaluate whether combination therapy with Lovaza (omega-3-acid ethyl esters) and Antara (fenofibrate) would result in a greater reduction in serum triglyceride levels in hypertriglyceridemic subjects than treatment with fenofibrate alone. This second extension of 24 months was to assess the continued efficacy of adjunctive Lovaza (omega-3-acid ethyl esters) \[formerly known as Omacor\] therapy in hypertriglyceridemic subjects treated with Antara (fenofibrate) in lowering serum triglyceride (TG) levels.

Detailed description

Three studies comprise this program. Study LOV111859/OM5 (double-blind study) was followed by two open label extensions - LOV111860/OM5X (1st open label extension - 8 weeks) and LOV111821/OM5XX (2nd open label extension - 24 months). Studies LOV111859/OM5 and LOV111860/OM5X are outlined in NCT00246636.
