CLINICAL STUDIES
14 14.1 Severe Hypertriglyceridemia The effects of omega-3-acid ethyl esters 4 grams per day were assessed in 2 randomized, placebo-controlled, double-blind, parallel-group trials of 84 adult subjects (42 on omega-3-acid ethyl esters, 42 on placebo) with very high triglyceride levels. Subjects whose baseline triglyceride levels were between 500 and 2,000 mg/dL were enrolled in these 2 trials of 6 and 16 weeks’ duration. The median triglyceride and LDL-C levels in these subjects were 792 mg/dL and 100 mg/dL, respectively. Median HDL-C level was 23.0 mg/dL. The changes in the major lipoprotein lipid parameters for the groups receiving omega-3-acid ethyl esters or placebo are shown in Table 2. Table 2. Median Baseline and Percent Change From Baseline in Lipid Parameters in Subjects With Severe Hypertriglyceridemia (≥500 mg/dL) Parameter Omega-3-acid ethyl esters N = 42 Placebo N = 42 Difference BL % Change BL % Change TG 816 -44.9 788 +6.7 -51.6 Non-HDL-C 271 -13.8 292 -3.6 -10.2 TC 296 -9.7 314 -1.7 -8.0 VLDL-C 175 -41.7 175 -0.9 -40.8 HDL-C 22 +9.1 24 0.0 +9.1 LDL-C 89 +44.5 108 -4.8 +49.3 BL = Baseline (mg/dL); % Change = Median Percent Change from Baseline; Difference = omega-3-acid ethyl esters Median % Change – Placebo Median % Change. Omega-3-acid ethyl esters 4 grams per day reduced median TG, VLDL-C, and non-HDL-C levels and increased median HDL-C from baseline relative to placebo. Treatment with omega-3-acid ethyl esters 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 omega-3-acid ethyl esters on the risk of pancreatitis has not been determined. The effect of omega-3-acid ethyl esters on cardiovascular mortality and morbidity has not been determined.

MECHANISM OF ACTION
12.1 Mechanism of Action The mechanism of action of omega-3-acid ethyl esters is not completely understood. Potential mechanisms of action include inhibition of acyl-CoA:1,2-diacylglycerol acyltransferase, increased mitochondrial and peroxisomal β-oxidation in the liver, decreased lipogenesis in the liver, and increased plasma lipoprotein lipase activity. Omega-3-acid ethyl esters may reduce the synthesis of triglycerides in the liver because EPA and DHA are poor substrates for the enzymes responsible for TG synthesis, and EPA and DHA inhibit esterification of other fatty acids.
INDICATIONS AND USAGE
1 Omega-3-acid ethyl esters capsules, USP are indicated as an adjunct to diet to reduce triglyceride (TG) levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia (HTG). Usage Considerations: Patients should be placed on an appropriate lipid-lowering diet before receiving omega-3-acid ethyl esters capsules, USP and should continue this diet during treatment with omega-3-acid ethyl esters capsules, USP. Laboratory studies should be done to ascertain that the lipid levels are consistently abnormal before instituting therapy with omega-3-acid ethyl esters. Every attempt should be made to control serum lipids with appropriate diet, exercise, weight loss in obese patients, and control of any medical problems such as diabetes mellitus and hypothyroidism that are contributing to the lipid abnormalities. Medications known to exacerbate hypertriglyceridemia (such as beta blockers, thiazides, estrogens) should be discontinued or changed if possible prior to consideration of triglyceride-lowering drug therapy. Limitations of Use: The effect of omega-3-acid ethyl esters capsules, USP on the risk for pancreatitis has not been determined. The effect of omega-3-acid ethyl esters capsules, USP on cardiovascular mortality and morbidity has not been determined.

PEDIATRIC USE
8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.
PREGNANCY
8.1 Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies in pregnant women. It is unknown whether omega-3-acid ethyl esters capsules can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Omega-3-acid ethyl esters capsules should be used during pregnancy only if the potential benefit to the patient justifies the potential risk to the fetus. Animal Data: Omega-3-acid ethyl esters have been shown to have an embryocidal effect in pregnant rats when given in doses resulting in exposures 7 times the recommended human dose of 4 grams/day based on a body surface area comparison. In female rats given oral gavage doses of 100, 600, and 2,000 mg/kg/day beginning 2 weeks prior to mating and continuing through gestation and lactation, no adverse effects were observed in the high-dose group (5 times human systemic exposure following an oral dose of 4 grams/day based on body surface area comparison). In pregnant rats given oral gavage doses of 1,000, 3,000, and 6,000 mg/kg/day from gestation day 6 through 15, no adverse effects were observed (14 times human systemic exposure following an oral dose of 4 grams/day based on a body surface area comparison). In pregnant rats given oral gavage doses of 100, 600, and 2,000 mg/kg/day from gestation day 14 through lactation day 21, no adverse effects were seen at 2,000 mg/kg/day (5 times the human systemic exposure following an oral dose of 4 grams/day based on a body surface area comparison). However, decreased live births (20% reduction) and decreased survival to postnatal day 4 (40% reduction) were observed in a dose-ranging study using higher doses of 3,000 mg/kg/day (7 times the human systemic exposure following an oral dose of 4 grams/day based on a body surface area comparison). In pregnant rabbits given oral gavage doses of 375, 750, and 1,500 mg/kg/day from gestation day 7 through 19, no findings were observed in the fetuses in groups given 375 mg/kg/day (2 times human systemic exposure following an oral dose of 4 grams/day based on a body surface area comparison). However, at higher doses, evidence of maternal toxicity was observed (4 times human systemic exposure following an oral dose of 4 grams/day based on a body surface area comparison).
NUSRING MOTHERS
8.3 Nursing Mothers Studies with omega-3-acid ethyl esters have demonstrated excretion in human milk. The effect of this excretion on the infant of a nursing mother is unknown; caution should be exercised when omega-3-acid ethyl esters capsules are administered to a nursing mother. An animal study in lactating rats given oral gavage 14C-ethyl EPA demonstrated that drug levels were 6 to 14 times higher in milk than in plasma.
WARNING AND CAUTIONS
5 WARNINGS AND PRECAUTIONS In patients with hepatic impairment, monitor ALT and AST levels periodically during therapy. (5.1) Omega-3-acid ethyl esters capsules may increase levels of LDL. Monitor LDL levels periodically during therapy. (5.1) Use with caution in patients with known hypersensitivity to fish and/or shellfish. (5.2) There is a possible association between omega-3-acid ethyl esters and more frequent recurrences of symptomatic atrial fibrillation or flutter in patients with paroxysmal or persistent atrial fibrillation, particularly within the first months of initiating therapy. (5.3) 5.1 Monitoring: Laboratory Tests In patients with hepatic impairment, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels should be monitored periodically during therapy with omega-3-acid ethyl esters capsules. In some patients, increases in ALT levels without a concurrent increase in AST levels were observed. In some patients, omega-3-acid ethyl esters capsule increases LDL-C levels. LDL-C levels should be monitored periodically during therapy with omega-3-acid ethyl esters. Laboratory studies should be performed periodically to measure the patient’s TG levels during therapy with omega-3-acid ethyl esters. 5.2 Fish Allergy Omega-3-acid ethyl esters capsules contain ethyl esters of omega-3 fatty acids (EPA and DHA) obtained from the oil of several fish sources. It is not known whether patients with allergies to fish and/or shellfish, are at increased risk of an allergic reaction to omega-3-acid ethyl esters capsules. Omega-3-acid ethyl esters capsules should be used with caution in patients with known hypersensitivity to fish and/or shellfish. 5.3 Recurrent Atrial Fibrillation (AF) or Flutter In a double-blind, placebo-controlled trial of 663 subjects with symptomatic paroxysmal AF (n=542) or persistent AF (n=121), recurrent AF or flutter was observed in subjects randomized to omega-3-acid ethyl esters who received 8 grams/day for 7 days and 4 grams/day thereafter for 23 weeks at a higher rate relative to placebo. Subjects in this trial had median baseline triglycerides of 127 mg/dL, had no substantial structural heart disease, were taking no anti-arrhythmic therapy (rate control permitted), and were in normal sinus rhythm at baseline. At 24 weeks, in the paroxysmal AF stratum, there were 129 (47%) first recurrent symptomatic AF or flutter events on placebo and 141 (53%) on omega-3-acid ethyl esters [primary endpoint, HR 1.19; 95% CI: 0.93, 1.35]. In the persistent AF stratum, there were 19 (35%) events on placebo and 34 (52%) events on omega-3-acid ethyl esters [HR 1.63; 95% CI: 0.91, 2.18]. For both strata combined, the HR was 1.25; 95% CI: 1.00, 1.40. Although the clinical significance of these results is uncertain, there is a possible association between omega-3-acid ethyl esters and more frequent recurrences of symptomatic atrial fibrillation or flutter in patients with paroxysmal or persistent atrial fibrillation, particularly within the first 2 to 3 months of initiating therapy. Omega-3-acid ethyl esters capsules are not indicated for the treatment of AF or flutter.
