A Second Open-Label Extension of a Double-Blind, Parallel, Phase IV Study to Assess the Efficacy and Safety of Adjunctive Lovaza® (Formerly Known as Omacor®) Therapy in Hypertriglyceridemic Subjects Treated With Antara™

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Subjects were men and women who had successfully completed the previous open-label extension study (LOV111860/OM5X) and had met all inclusion and exclusion criteria for the original double-blind study (LOV111859/OM5) and throughout LOV111860/OM5X, or who had a renewed waiver of a previously approved protocol deviation.

Eligibility for entry into this study was based on the inclusion/exclusion criteria described of the double-blind LOV111859/OM5 protocol.

Subjects were men and women who had successfully completed the previous open-label extension study (LOV111860/OM5X) and had met all inclusion and exclusion criteria for the original double-blind study (LOV111859/OM5) and throughout LOV111860/OM5X, or who had a renewed waiver of a previously approved protocol deviation. The main eligibility criteria for LOV111859/OM5 were,

  • 18 to79 years of age (inclusive) at screening
  • fasting serum TG levels ≥500 mg/dL and <1300 mg/dL
  • BMI ≥ 25 kg/m2 and ≤43 kg/m2.

Subjects enrolled directly from the end of LOV111860/OM5X into LOV111821/OM5XX.
