While LOVAZA®’s method of action is not understood, clinical trials demonstrated efficacy in lowering triglycerides in individuals with very high TG levels.
Clinical Studies
Severe Hypertriglyceridemia
The effects of LOVAZA® 4 grams/day were assessed in 2 randomized, placebo-controlled, double-blind, parallel-group trials of 84 adult subjects (42 on LOVAZA®, 42 on placebo) with very high TG levels. Subjects whose baseline TG levels were between 500 and 2,000 mg/dL were enrolled in these 2 trials of 6 and 16 weeks’ duration. The median TG and LDL-C levels in these subjects were 792 mg/dL and 100 mg/dL, respectively. Median high-density lipoprotein cholesterol (HDL-C) level was 23 mg/dL.
The changes in the major lipoprotein lipid parameters for the groups receiving LOVAZA® or placebo are shown in Table 2.

LOVAZA® 4 grams/day reduced median TG, VLDL-C, and non-HDL-C levels and increased median HDL-C from baseline relative to placebo. Treatment with LOVAZA® to reduce very high TG levels may result in elevations in LDL-C and non-HDL-C in some individuals. Patients should be monitored to ensure that the LDL-C level does not increase excessively.
The effect of LOVAZA® on the risk of pancreatitis has not been determined.
The effect of LOVAZA® on cardiovascular mortality and morbidity has not been determined.
