The purpose of OM6 is to evaluate efficacy and safety of Lovaza (omega-3-acid ethyl esters) [formerly known as Omacor] combined with simvastatin for lowering non-high-density lipoprotein cholesterol (non-HDL-C) in subjects with persistent high triglycerides despite statin therapy.

Additionally, a two-year extension trial (LOV111818/OM6X) is posted on NCT00903409.

Primary Outcome Measures:
  • Difference between simvastatin + Lovaza (omega-3-acid ethyl esters) [formerly known as Omacor] and simvastatin + placebo treatment groups in the percent change from baseline to end-of-treatment in non-high-density lipoprotein cholesterol [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
