Open-Label Extension of a Randomized, Double-Blind, Placebo-Controlled Study to Assess the Efficacy and Safety of Lovaza® and Simvastatin Therapy in Hypertriglyceridemic Subjects - Full Text View

Purpose

In a previous trial (LOV111858/OM6), subjects received in a double-blind fashion either 4 g/day of Lovaza® (omega-3-ethyl esters) [formerly known as Omacor] co-administered with simvastatin 40 mg/day or placebo co-administered with simvastatin 40 mg/day for 8 weeks. This extension trial, LOV111818/OM6X assessed the continued efficacy and safety of Lovaza® (omega-3-ethyl esters) co-administered with simvastatin 40 mg vs. switching from simvastatin plus placebo to simvastatin plus Lovaza® for lowering non-High Density Lipoprotein-Cholesterol (non-HDL-C) levels at 4 months (primary endpoint) and additionally at 12 and 24 months.

Primary Outcome Measures:

Median Percent Change of Non-HDL-C (High Density Lipoprotein-Cholesterol) in Switchers vs. Non-Switchers Subjects From LOV111858 End-of-Treatment (Week 8) to Month 4 of Extension Study (LOV111818) [ Time Frame: Month 4 (LOV111818) ] [ Designated as safety issue: No ]
Median percent change from LOV111858 (NCT00903409) End-of-Treatment (double-blind study, Week 8) to the Month 4 visit of LOV111818 (open-label extension trial)

Secondary Outcome Measures:

Median Percent Change of Lipid Measurements From LOV111858 End-of-Treatment Week 8 to Months 4, 12, and 24 of the Open-Label Extension Study (LOV111818) in "Switchers" vs. Non-switchers [ Time Frame: Months 4, 12, and 24 (LOV111818) of the open-label extension trial ] [ Designated as safety issue: No ]
Median percent change from LOV111858 Baseline to LOV111818 Months 4, 12, and 24 visits of the open-label extension trial
Median Percent Change of Lipid Measurements From LOV111858 End-of-Treatment Week 8 to LOV111818 Months 4, 12, and 24 of the Open-Label Extension Trial [ Time Frame: LOV111858 End-of-Treatment (Week 8) to LOV111818 Months 4, 12, and 24 of the open-label extension trial ] [ Designated as safety issue: No ]
Median percent change from LOV111858 End-of-Treatment (Week 8) to LOV111818 Months 4, 12, and 24 visits of the open-label extension trial
