Each 1-gram capsule of LOVAZA (omega-3-acid ethyl esters) contains at least 900 mg of the ethyl esters of omega-3 fatty acids. These are predominantly a combination of ethyl esters of eicosapentaenoic acid (EPA - approximately 465 mg) and docosahexaenoic acid (DHA - approximately 375 mg). The structural formula of EPA ethyl ester is: The empirical formula of EPA ethyl ester is C22H34O2, and the molecular weight of EPA ethyl ester is 330.51. The structural formula of DHA ethyl ester is: The empirical formula of DHA ethyl ester is C24H36O2, and the molecular weight of DHA ethyl ester is 356.55. LOVAZA capsules also contain the following inactive ingredients: 4 mg α-tocopherol (in a carrier of partially hydrogenated vegetable oils including soybean oil), and gelatin, glycerol, and purified water (components of the capsule shell). CLINICAL PHARMACOLOGY Mechanism of Action The mechanism of action of LOVAZA 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. LOVAZA may reduce the synthesis of triglycerides (TGs) 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. Pharmacokinetic and Bioavailability Studies In healthy volunteers and in patients with hypertriglyceridemia (HTG), EPA and DHA were absorbed when administered as ethyl esters orally. Omega-3-acids administered as ethyl esters (LOVAZA) induced significant, dose–dependent increases in serum phospholipid EPA content, though increases in DHA content were less marked and not dose-dependent when administered as ethyl esters. Uptake of EPA and DHA into serum phospholipids in subjects t reated with LOVAZA was independent of age (<49 years versus ≥49 years). Females tended to have more uptake of EPA into serum phospholipids than males. Pharmacokinetic data on LOVAZA in children are not available. Drug Interactions Cytochrome P450-Dependent Monooxygenase Activities The effect of a mixture of free fatty acids (FFA), EPA/DHA and their FFA-albumin conjugate on cytochrome P450-dependent monooxygenase activities was assessed in human liver microsomes. At the 23 micromole concentration, FFA resulted in a less than 32% inhibition of CYP1A2, 2A6, 2C9, 2C19, 2D6, 2E1, and 3A. At the 23 micromole concentration, the FFA-albumin conjugate resulted in a less than 20% inhibition of CYP2A6, 2C19, 2D6, and 3A, with a 68% inhibition being seen for CYP2E1. Since the free forms of the EPA and DHA are undetectable in the circulation (<1 micromole), clinically significant drug-drug interactions due to inhibition of P450-mediated metabolism EPA/DHA combinations are not expected in humans. CLINICAL STUDIES High Triglycerides Add-on to HMG-CoA reductase inhibitor therapy The effects of LOVAZA 4 g per day as add-on therapy to treatment with simvastatin were evaluated in a randomized, placebo-controlled, double-blind, parallel-group study of 254 adult patients (122 on LOVAZA and 132 on placebo) with persistent high triglycerides (200 to 499 mg/dL) despite simvastatin therapy (Table 1). Patients were treated with open-label simvastatin 40 mg per day for 8 weeks prior to randomization to control their LDL-C to no greater than 10% above NCEP ATP III goal and remained on this dose throughout the study. Following 8 weeks of open-label treatment with simvastatin, patients were randomized to either LOVAZA 4 g per day or placebo for an additional 8 weeks with simvastatin co-therapy. The median baseline triglyceride and LDL-C levels in these patients were 268 mg/dL and 89 mg/dL, respectively. Median baseline non-HDL-C and HDL-C levels were 138 mg/dL and 45 mg/dL, respectively. The changes in the major lipoprotein lipid parameters for the groups receiving LOVAZA plus simvastatin and placebo plus simvastatin are shown in Table 1.
BL = Baseline (mg/dL); EOT = End of Treatment (mg/dL); Median % Change = Median Percent Change from Baseline; Difference = LOVAZA Median % Change – Placebo Median % Change LOVAZA 4 g per day significantly reduced non-HDL-C, TG, TC, VLDL-C, and Apo-B levels and increased HDL-C and LDL-C from baseline relative to placebo. Very High Triglycerides Monotherapy The effects of LOVAZA 4 g per day were assessed in 2 randomized, placebo-controlled, double-blind, parallel-group studies of 84 adult patients (42 on LOVAZA, 42 on placebo) with very high triglyceride levels (Table 2). Patients whose baseline triglyceride levels were between 500 and 2,000 mg/dL were enrolled in these 2 studies of 6 and 16 weeks’ duration. The median triglyceride and LDL-C levels in these patients 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 LOVAZA or placebo are shown in Table 2.
BL = Baseline (mg/dL); % Chg = Median Percent Change from Baseline; Difference = LOVAZA Median % change – Placebo Median % Change LOVAZA 4 g per 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 in patients with very high TG levels has not been evaluated. The effect of LOVAZA on cardiovascular mortality and morbidity in patients with elevated TG levels has not been determined. INDICATIONS AND USAGE Very High Triglycerides LOVAZA is indicated as an adjunct to diet to reduce triglyceride (TG) levels in adult patients with very high (≥500 mg/dL) triglyceride levels. Usage Considerations In individuals with hypertriglyceridemia (HTG), excess body weight and excess alcohol intake may be important contributing factors and should be addressed before initiating any drug therapy. Physical exercise can be an important ancillary measure. Diseases contributory to hyperlipidemia, (such as hypothyroidism or diabetes mellitus) should be looked for and adequately treated. Estrogen therapy, thiazide diuretics, and beta blockers are sometimes associated with massive rises in plasma TG levels. In such cases, discontinuation of the specific etiologic agent, if medically indicated, may obviate the need for specific drug therapy for HTG. The use of lipid-regulating agents should be considered only when reasonable attempts have been made to obtain satisfactory results with non-drug methods. If the decision is made to use lipid-regulating agents, the patient should be advised that use of lipid-regulating agents does not reduce the importance of adhering to diet (see PRECAUTIONS). CONTRAINDICATIONS LOVAZA is contraindicated in patients who exhibit hypersensitivity (e.g., anaphylactic reaction) to any component of this medication. PRECAUTIONS General Initial Therapy Laboratory studies should be performed to ascertain that the patient’s TG levels are consistently abnormal before instituting therapy with LOVAZA. Every attempt should be made to control serum TG levels with appropriate diet, exercise, weight loss in overweight patients, and control of any medical problems (such as diabetes mellitus and hypothyroidism) that may be contributing to the patient’s TG abnormalities. Medications known to exacerbate HTG (such as beta blockers, thiazides, and estrogens) should be discontinued or changed, if possible, before considering TG–lowering drug therapy. Continued Therapy Laboratory studies should be performed periodically to measure the patient’s TG levels during therapy with LOVAZA. Therapy with LOVAZA should be withdrawn in patients who do not have an adequate response after 2 months of treatment. Information for Patients LOVAZA should be used with caution in patients with known sensitivity or allergy to fish. Patients should be advised that use of lipid-regulating agents does not reduce the importance of adhering to diet. Laboratory Tests In some patients, increases in alanine aminotransferase (ALT) levels without a concurrent increase in aspartate aminotransferase (AST) levels were observed. Alanine aminotransferase levels should be monitored periodically during therapy with LOVAZA. In some patients, LOVAZA increased low-density lipoprotein cholesterol (LDL-C) levels. As with any lipid-regulating product, LDL-C levels should be monitored periodically during therapy with LOVAZA. Drug Interactions Anticoagulants Some studies with omega-3-acids demonstrated prolongation of bleeding time. The prolongation of bleeding time reported in these studies has not exceeded normal limits and did not produce clinically significant bleeding episodes. Clinical studies have not been done to thoroughly examine the effect of LOVAZA and concomitant anticoagulants. Patients receiving treatment with both LOVAZA and anticoagulants should be monitored periodically. HMG-CoA reductase inhibitors In a 14-day study of 24 healthy adult subjects, daily co-administration of simvastatin 80 mg with LOVAZA 4 g did not affect the extent (AUC) or rate (Cmax) of exposure to simvastatin or the major active metabolite, beta-hydroxy simvastatin at steady state. Cytochrome P450-Dependent Monooxygenase Activities Omega-3 fatty-acid-containing products have been shown to increase hepatic concentrations of cytochrome P450 and activities of certain P450 enzymes in rats. The potential of LOVAZA to induce P450 activities in humans has not been studied. Carcinogenesis, Mutagenesis, Impairment of Fertility In a rat carcinogenicity study with oral gavage doses of 100, 600, and 2,000 mg/kg/day, males were treated with omega-3-acid ethyl esters for 101 weeks and females for 89 weeks without an increased incidence of tumors (up to 5 times human systemic exposures following an oral dose of 4 g/day based on a body surface area comparison). Standard lifetime carcinogenicity bioassays were not conducted in mice. Omega-3-acid ethyl esters were not mutagenic or clastogenic with or without metabolic activation in the bacterial mutagenesis (Ames) test with Salmonella typhimurium and Escherichia coli or in the chromosomal aberration assay in Chinese hamster V79 lung cells or human lymphocytes. Omega-3-acid ethyl esters were negative in the in vivo mouse micronucleus assay. In a rat fertility study with oral gavage doses of 100, 600, and 2,000 mg/kg/day, males were treated for 10 weeks prior to mating and females were treated for 2 weeks prior to and throughout mating, gestation, and lactation. No adverse effect on fertility was observed at 2,000 mg/kg/day (5 times human systemic exposure following an oral dose of 4 g/day based on a body surface area comparison). Pregnancy Category C There are no adequate and well-controlled studies in pregnant women. It is unknown whether LOVAZA can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. LOVAZA should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 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 g/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 g/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 g/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 g/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 g/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 g/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 g/day based on a body surface area comparison). Nursing Mothers It is not known whether omega-3-acid ethyl esters are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when LOVAZA is administered to a woman who is breastfeeding. Pediatric Use Safety and effectiveness in pediatric patients under 18 years of age have not been established. Geriatric Use A limited number of patients older than 65 years were enrolled in the clinical studies. Safety and efficacy findings in subjects older than 60 years did not appear to differ from those of subjects younger than 60 years. ADVERSE REACTIONS Treatment-emergent adverse events reported in at least 1% of patients treated with LOVAZA 4 g per day or placebo during 8 randomized, placebo-controlled, double-blind, parallel-group studies for HTG are listed in Table 3. Adverse events led to discontinuation of treatment in 3.5% of patients treated with LOVAZA and 2.6% of patients treated with placebo.
Adverse events were coded using COSTART, version 5.0. Subjects were counted only once for each body system and for each preferred term. *Placebo was corn oil for all studies. Additional adverse events reported by 1 or more patients from 22 clinical studies for HTG are listed below: Body as a Whole Enlarged abdomen, asthenia, body odor, chest pain, chills, suicide, fever, generalized edema, fungal infection, malaise, neck pain, neoplasm, rheumatoid arthritis, and sudden death.

Special Senses Cataract. Urogenital System Cervix disorder, endometrial carcinoma, epididymitis, and impotence. Postmarketing Experience In addition to adverse reactions reported from clinical trials, the events described below have been identified during post-approval use of LOVAZA. 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. DRUG ABUSE AND DEPENDENCE LOVAZA does not have any known drug abuse or withdrawal effects. OVERDOSAGE In the event of an overdose, the patient should be treated symptomatically, and general supportive care measures instituted, as required. DOSAGE AND ADMINISTRATION Patients should be placed on an appropriate lipid-lowering diet before receiving LOVAZA, and should continue this diet during treatment with LOVAZA. In clinical studies, LOVAZA was administered with meals. The daily dose of LOVAZA is 4 g per day. The daily dose may be taken as a single 4-g dose (4 capsules) or as two 2-g doses (2 capsules given twice daily).
