Omega-3-Acid Ethyl Esters

1 INDICATIONS AND USAGE Omega-3-acid ethyl esters capsules are indicated as an adjunct to diet to reduce triglyceride (TG) levels in adult patients with severe (greater than or equal to 500 mg per dL) hypertriglyceridemia (HTG). Omega-3-acid ethyl esters capsules are a combination of ethyl esters of omega 3 fatty acids, principally eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), indicated as an adjunct to diet to reduce triglyceride (TG) levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia (HTG). ( 1 ) Limitations of Use: The effect of omega-3-acid ethyl esters on the risk for pancreatitis has not been determined. ( 1 ) The effect of omega-3-acid ethyl esters on cardiovascular mortality and morbidity has not been determined. ( 1 ) Usage Considerations: Patients should be placed on an appropriate lipid-lowering diet before receiving omega-3-acid ethyl esters and should continue this diet during treatment with omega-3-acid ethyl esters. 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 on the risk for pancreatitis has not been determined. The effect of omega-3-acid ethyl esters on cardiovascular mortality and morbidity has not been determined.

2 DOSAGE AND ADMINISTRATION Assess triglyceride levels carefully before initiating therapy. Identify other causes (e.g., diabetes mellitus, hypothyroidism, medications) of high triglyceride levels and manage as appropriate [see Indications and Usage (1) ]. Patients should be placed on an appropriate lipid-lowering diet before receiving omega-3-acid ethyl esters, and should continue this diet during treatment with omega-3-acid ethyl esters. In clinical studies, omega-3-acid ethyl esters was administered with meals. The daily dose of omega-3-acid ethyl esters is 4 grams per day. The daily dose may be taken as a single 4-gram dose (4 capsules) or as two 2-gram doses (2 capsules given twice daily). Patients should be advised to swallow omega-3-acid ethyl esters whole. Do not break open, crush, dissolve, or chew omega-3-acid ethyl esters.

4 CONTRAINDICATIONS Omega-3-acid ethyl esters are contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to omega-3-acid ethyl esters or any of its components. Omega-3-acid ethyl esters are contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to omega-3-acid ethyl esters or any of its components. ( 4 )

5 WARNINGS AND PRECAUTIONS In patients with hepatic impairment, monitor ALT and AST levels periodically during therapy. ( 5.1 ) Omega-3-acid ethyl esters 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. In some patients, increases in ALT levels without a concurrent increase in AST levels were observed. In some patients, omega-3-acid ethyl esters 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 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. Omega-3-acid ethyl esters 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 per day for 7 days and 4 grams per day thereafter for 23 weeks at a higher rate relative to placebo. Subjects in this trial had median baseline triglycerides of 127 mg per 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 or 3 months of initiating therapy. Omega-3-acid ethyl esters are not indicated for the treatment of AF or flutter.

7 DRUG INTERACTIONS Omega-3-acids may prolong bleeding time. Patients taking omega-3-acid ethyl esters and an anticoagulant or other drug affecting coagulation (e.g., anti-platelet agents) should be monitored periodically. ( 7.1 ) 7.1 Anticoagulants or Other Drugs Affecting Coagulation Some trials with omega-3-acids demonstrated prolongation of bleeding time. The prolongation of bleeding time reported in these trials has not exceeded normal limits and did not produce clinically significant bleeding episodes. Clinical trials have not been done to thoroughly examine the effect of omega-3-acid ethyl esters and concomitant anticoagulants. Patients receiving treatment with omega-3-acid ethyl esters and an anticoagulant or other drug affecting coagulation (e.g., anti-platelet agents) should be monitored periodically.

6 ADVERSE REACTIONS The most common adverse reactions (incidence >3% and greater than placebo) were eructation, dyspepsia, and taste perversion.

Metabolic and Nutritional Disorders Increased ALT and increased AST. Skin Pruritus and rash. 6.2 Postmarketing Experience In addition to adverse reactions reported from clinical trials, the events described below have been identified during post-approval use of omega-3-acid ethyl esters. Because these events are reported voluntarily from a population of unknown size, it is not possible to reliably estimate their frequency or to always establish a causal relationship to drug exposure. The following events have been reported: anaphylactic reaction, hemorrhagic diathesis, urticaria.

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 can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity.Omega-3-acid ethyl esters 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 per day based on a body surface area comparison. In female rats given oral gavage doses of 100, 600, and 2,000 mg per kg per 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 per day based on body surface area comparison). In pregnant rats given oral gavage doses of 1,000, 3,000, and 6,000 mg per kg per day from gestation Day 6 through 15, no adverse effects were observed (14 times human systemic exposure following an oral dose of 4 grams per day based on a body surface area comparison). In pregnant rats given oral gavage doses of 100, 600, and 2,000 mg per kg per day from gestation Day 14 through lactation Day 21, no adverse effects were seen at 2,000 mg per kg per day (5 times the human systemic exposure following an oral dose of 4 grams per 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 per kg per day (7 times the human systemic exposure following an oral dose of 4 grams per day based on a body surface area comparison). In pregnant rabbits given oral gavage doses of 375, 750, and 1,500 mg per kg per day from gestation Day 7 through 19, no findings were observed in the fetuses in groups given 375 mg per kg per day (2 times human systemic exposure following an oral dose of 4 grams per 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 per day based on a body surface area comparison).
