  Purpose

The purpose of OM5/LOV111859 was to evaluate efficacy and safety of Omacor (omega-3-acid ethyl esters) as add-on therapy to Antara (fenofibrate) and diet for the treatment of patients with very high triglycerides.

The purpose of both OM5X/LOV111860 was to assess the continued efficacy and safety of adjunctive Lovaza (omega-3-acid ethyl esters) therapy in hypertriglyceridemic subjects treated with fenofibrate in lowering serum triglyceride (TG) levels.

Primary Outcome Measures:
  • OM5X/LOV111860 - Difference between double-blind Lovaza (omega-3-acid ethyl esters) + fenofibrate (Group 1) and placebo + fenofibrate (Group 2) treatment groups in percent change in fasting serum TG level from baseline of OM5 to end of OM5X [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • OM5/LOV111859 - Difference between Lovaza (omega-3-acid ethyl esters) [formerly known as Omacor]+ fenofibrate and placebo + fenofibrate treatment groups in percent change in TG level from baseline [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • OM5X/LOV111860 - Difference between double-blind Lovaza (omega-3-acid ethyl esters) + fenofibrate (Group 1) and placebo + fenofibrate (Group 2) treatment groups in percent change for other lipid and biomarkers from baseline of OM5 to end of OM5X [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • OM5/LOV111859 - Difference between Lovaza (omega-3-acid ethyl esters) + fenofibrate and placebo + fenofibrate treatment groups in percent change for other lipid and biomarkers from baseline [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
