fenofibric acid tablet
FULL PRESCRIBING INFORMATION
1 INDICATIONS AND USAGE
1.1 Severe Hypertriglyceridemia
FIBRICOR is indicated as adjunctive therapy to diet for treatment of severe hypertriglyceridemia (≥ 500 mg/dl). Improving glycemic control in diabetic patients showing fasting chylomicronemia will usually obviate the need for pharmacologic intervention.
Levels of serum triglycerides > 1000 mg/dl may increase the risk of developing pancreatitis. The effect of FIBRICOR on reducing this risk has not been studied.
1.2 Primary Hyperlipidemia or Mixed Dyslipidemia
FIBRICOR is indicated as adjunctive therapy to diet to reduce elevated LDL-C, Total-C, TG, and Apo B, and to increase HDL-C in patients with primary hypercholesterolemia or mixed dyslipidemia.
1.3 Considerations of Treatment
Fenofibrate at a dose equivalent to 105 mg of FIBRICOR was not shown to reduce coronary heart disease morbidity and mortality in a large, randomized controlled trial of patients with type 2 diabetes mellitus [see Warnings and Precautions (5.6)].
The active moiety of FIBRICOR is fenofibric acid. The pharmacological effects of fenofibric acid have been extensively studied through oral administration of fenofibrate, which is converted in vivo to fenofibric acid.
2 DOSAGE AND ADMINISTRATION
2.1 Dosing Information
FIBRICOR can be given without regard to meals.
Patients should be placed on an appropriate lipid-lowering diet before receiving FIBRICOR and should continue this diet during treatment with fenofibric acid.
Laboratory studies should be done to ascertain that the lipid levels are consistently abnormal before instituting FIBRICOR therapy. 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 (beta blockers, thiazides, estrogens) should be discontinued or changed if possible prior to consideration of triglyceride-lowering drug therapy.
Periodic determination of serum lipids should be obtained during initial therapy in order to establish the lowest effective dose of FIBRICOR. Therapy should be withdrawn in patients who do not have an adequate response after two months of treatment with the maximum recommended dose of 105 mg per day.
Consideration should be given to reducing the dosage of FIBRICOR if lipid levels fall significantly below the targeted range.
2.2 Recommended Adult Dose
Severe Hypertriglyceridemia: The initial dose is 35 to 105 mg per day. Dosage should be individualized according to patient response, and should be adjusted if necessary following repeat lipid determinations at 4 to 8 week intervals.
2.3 Renal Impairment
In patients with mild-to-moderate renal impairment, treatment with FIBRICOR should be initiated at a dose of 35 mg/day, and increased only after evaluation of the effects on renal function and lipid levels at this dose. The use of FIBRICOR should be avoided in patients with severe renal impairment [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].
2.4 Geriatric Patients
Dose selection for the elderly should be made on the basis of renal function [see Use in Specific Populations (8.6)].
3 DOSAGE FORMS AND STRENGTHS
FIBRICOR is contraindicated in patients with:
5 WARNINGS AND PRECAUTIONS
5.1 Abnormal Liver Tests
Fenofibrate (administered over a range of doses with the higher dose equivalent to 105 mg fenofibric acid) has been associated with increases in serum transaminases [AST (SGOT) or ALT (SGPT)].
In a pooled analysis of 10 placebo-controlled trials, increases to > 3 times the upper limit of normal of ALT occurred in 5.3% of patients taking fenofibrate versus 1.1% of patients treated with placebo. The incidence of increases in transaminases observed with fenofibrate therapy may be dose related.
Chronic active hepatocellular and cholestatic hepatitis associated with fenofibrate therapy have been reported after exposures of weeks to several years. In extremely rare cases, cirrhosis has been reported in association with chronic active hepatitis.
Periodic monitoring of liver tests (e.g., ALT) should be performed for the duration of therapy with FIBRICOR, and therapy discontinued if enzyme levels persist above three times the normal limit.
FIBRICOR, like fenofibrate, clofibrate and gemfibrozil, may increase cholesterol excretion into the bile, leading to cholelithiasis. If cholelithiasis is suspected, gallbladder studies are indicated. FIBRICOR therapy should be discontinued if gallstones are found.
5.3 Concomitant Use with Oral Anticoagulants
Caution should be exercised when FIBRICOR is given in conjunction with oral anticoagulants. FIBRICOR may potentiate the anticoagulant effects of these agents resulting in prolongation of the prothrombin time/INR. Frequent monitoring of prothrombin time/INR and dose adjustment of the anticoagulant are recommended until the prothrombin time/INR has stabilized in order to prevent bleeding complications [see Drug Interactions (7.1)].
Fibrates increase the risk for myopathy and have been associated with rhabdomyolysis. The risk for serious muscle toxicity appears to be increased in elderly patients and in patients with diabetes, renal failure, or hypothyroidism.
Data from observational studies suggest that the risk for rhabdomyolysis is increased when fibrates, in particular gemfibrozil, are co-administered with an HMG-CoA reductase inhibitor (statin).
Myopathy should be considered in any patient with diffuse myalgias, muscle tenderness or weakness, and/or marked elevations of creatine phosphokinase levels.
Patients should be advised to report promptly unexplained muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever. CPK levels should be assessed in patients reporting these symptoms, and FIBRICOR therapy should be discontinued if markedly elevated CPK levels occur or myopathy is diagnosed.
5.5 Elevated Serum Creatinine
Elevations in serum creatinine have been reported in patients on fenofibrate. These elevations tend to return to baseline following discontinuation of fenofibrate. The clinical significance of these observations is unknown. Renal monitoring should be considered for patients with renal impairment and for patients at risk for renal insufficiency, such as the elderly and patients with diabetes.
5.6 Coronary Heart Disease Morbidity and Mortality
The effect of FIBRICOR on coronary heart disease morbidity and mortality and non-cardiovascular mortality has not been established.
The Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study was a 5 year randomized, placebo-controlled study of 9795 patients with type 2 diabetes mellitus treated with fenofibrate. Fenofibrate demonstrated a non-significant 11% relative reduction in the primary outcome of coronary heart disease events (hazard ratio [HR] 0.89, 95% CI 0.75–1.05, p=0.16) and a significant 11% reduction in the secondary outcome of total cardiovascular disease events (HR 0.89 [0.80–0.99], p=0.04). There was a non-significant 11% (HR 1.11 [0.95, 1.29], p=0.18) and 19% (HR 1.19 [0.90, 1.57], p=0.22) increase in total and coronary heart disease mortality, respectively, with fenofibrate as compared to placebo.
Because of chemical, pharmacological, and clinical similarities between fenofibrate, clofibrate, and gemfibrozil, the adverse findings in 4 large randomized, placebo-controlled clinical studies with these other fibrate drugs may also apply to fenofibric acid.
In the Coronary Drug Project, a large study of post myocardial infarction of patients treated for 5 years with clofibrate, there was no difference in mortality seen between the clofibrate group and the placebo group. There was however, a difference in the rate of cholelithiasis and cholecystitis requiring surgery between the two groups (3.0% vs. 1.8%).
In a study conducted by the World Health Organization (WHO), 5000 subjects without known coronary artery disease were treated with placebo or clofibrate for 5 years and followed for an additional one year. There was a statistically significant, higher age – adjusted all-cause mortality in the clofibrate group compared with the placebo group (5.70% vs. 3.96%, p<0.01). Excess mortality was due to a 33% increase in non-cardiovascular causes, including malignancy, post-cholecystectomy complications, and pancreatitis. This appeared to confirm the higher risk of gallbladder disease seen in clofibrate-treated patients studied in the Coronary Drug Project.
The Helsinki Heart Study was a large (n=4081) study of middle-aged men without a history of coronary artery disease. Subjects received either placebo or gemfibrozil for 5 years, with a 3.5 year open extension afterward. Total mortality was numerically higher in the gemfibrozil randomization group but did not achieve statistical significance (p=0.19, 95% confidence interval for relative risk = 0.91–1.64). Although cancer deaths trended higher in the gemfibrozil group (p=0.11), cancers (excluding basal cell carcinoma) were diagnosed with equal frequency in both study groups. Due to the limited size of the study, the relative risk of death from any cause was not shown to be different than that seen in the 9 year follow-up data from World Health Organization study (relative risk=1.29). Similarly, the numerical excess of gallbladder surgeries in the gemfibrozil group did not differ statistically from that observed in the WHO study.
A secondary prevention component of the Helsinki Heart Study enrolled middle-aged men excluded from the primary prevention study because of known or suspected coronary heart disease. Subjects received gemfibrozil or placebo for 5 years. Although cardiac deaths trended higher in the gemfibrozil group, this was not statistically significant (HR 2.2, 95% confidence interval: 0.94–5.05). The rate of gallbladder surgery was not statistically significant between study groups, but did trend higher in the gemfibrozil group, (1.9% vs. 0.3%, p=0.07). There was a statistically significant difference in the number of appendectomies in the gemfibrozil group (6/311 vs. 0/317, p=0.029).
Pancreatitis has been reported in patients taking fenofibrate. This occurrence may represent a failure of efficacy in patients with severe hypertriglyceridemia, a direct drug effect, or a secondary phenomenon mediated through biliary tract stone or sludge formation with obstruction of the common bile duct.
5.8 Venothromboembolic Disease
In the FIELD trial, pulmonary embolus (PE) and deep vein thrombosis (DVT) were observed at higher rates in the fenofibrate- than the placebo-treated group. Of 9,795 patients enrolled in FIELD, there were 4,900 in the placebo group and 4,875 in the fenofibrate group. For DVT, there were 48 events (1%) in the placebo group and 67 (1%) in the fenofibrate group (p=0.074); and for PE, there were 32 (0.7%) events in the placebo group and 53 (1%) in the fenofibrate group (p=0.022).
In the Coronary Drug Project, a higher proportion of the clofibrate group experienced definite or suspected fatal or nonfatal pulmonary embolism or thrombophlebitis than the placebo group (5.2% vs. 3.3% at five years; p<0.01).
5.9 Hypersensitivity Reactions
Acute hypersensitivity reactions including severe skin rashes such as Stevens-Johnson syndrome and toxic epidermal necrolysis requiring patient hospitalization and treatment with steroids have been reported in individuals treated with fenofibrate.
5.10 Hematological Changes
Mild-to-moderate hemoglobin, hematocrit, and white blood cell decreases have been observed in patients following initiation of fenofibrate therapy. Thrombocytopenia and agranulocytosis have been reported in individuals treated with fenofibrate. Periodic monitoring of red and white blood cell counts is recommended during the first 12 months of FIBRICOR administration.
6 ADVERSE REACTIONS
6.1 Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Adverse reactions reported by 2% or more of patients treated with fenofibrate (and greater than placebo) during the double-blind, placebo-controlled trials are listed in Table 1. Adverse reactions led to discontinuation of treatment in 5% of patients treated with fenofibrate and in 3% treated with placebo. Increases in liver tests were the most frequent events, causing discontinuation of fenofibrate treatment in 1.6% of patients.
6.2 Postmarketing Experience
The following adverse reactions have been identified during postapproval use of fenofibrate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: myalgia, rhabdomyolysis, increased creatinine phosphokinase, pancreatitis, increased alanine aminotranaminase, increased aspartate aminotranaminase, muscle spasm, acute renal failure, hepatitis, cirrhosis, nausea, abdominal pain, anemia, headache, arthralgia and asthenia.
7 DRUG INTERACTIONS
7.1 Oral Anticoagulants
Caution should be exercised when FIBRICOR is given in conjunction with coumarin anticoagulants. FIBRICOR may potentiate the anticoagulant effect of these agents resulting in prolongation of the prothrombin time/INR. Frequent monitoring of prothrombin time/INR and dose adjustment of the oral anticoagulant are recommended until the prothrombin time/INR has stabilized in order to prevent bleeding complications [see Warnings and Precautions (5.3)].
7.2 Bile-Acid Binding Resins
Since bile-acid binding resins may bind other drugs given concurrently, patients should take FIBRICOR at least 1 hour before or 4 to 6 hours after taking another drug.
Immunosuppressant agents such as cyclosporine and tacrolimus can impair renal function. When immunosuppressants and other potentially nephrotoxic agents are co-administered with FIBRICOR, the lowest effective dose of FIBRICOR should be employed and renal function should be monitored.
8 USE IN SPECIFIC POPULATIONS
Pregnancy Category C: Safety in pregnant women has not been established. There are no adequate and well controlled studies of FIBRICOR in pregnant women. FIBRICOR should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
In female rats given oral dietary doses of 15, 75, and 300 mg/kg/day of fenofibrate from 15 days prior to mating through weaning, maternal toxicity was observed at a dose that results in exposure to fenofibric acid that is 50 times that at the MRHD of fenofibric acid.
In pregnant rats given oral dietary doses of 14, 127, and 361 mg/kg/day from gestation day 6–15 during the period of organogenesis, adverse developmental findings were not observed at 14 mg/kg/day (a dose that results in exposure to fenofibric acid that is approximately twice that at the MRHD of fenofibric acid). At higher multiples of human doses evidence of maternal toxicity was observed.
In pregnant rabbits given oral gavage doses of 15, 150, and 300 mg/kg/day from gestation day 6–18 during the period of organogenesis and allowed to deliver, aborted litters were observed at 150 mg/kg/day (20 times that at the MRHD of fenofibric acid). No developmental findings were observed at 15 mg/kg/day (an exposure to fenofibric acid that is 7 times that at the MRHD of fenofibric acid).
In pregnant rats given oral dietary doses of 15, 75, and 300 mg/kg/day from gestation day 15 through lactation day 21 (weaning), maternal toxicity was observed at an exposure to fenofibric acid that is approximately 50 times that at the MRHD of fenofibric acid [see Nonclinical Toxicology (13.1)].
8.3 Nursing Mothers
FIBRICOR should not be used by nursing mothers. A decision should be made whether to discontinue nursing or to discontinue the drug [see Contraindications (4)].
8.4 Pediatric Use
Safety and effectiveness of FIBRICOR in pediatric patients have not been established.
8.5 Geriatric Use
FIBRICOR is substantially excreted by the kidney as fenofibric acid and fenofibric acid glucuronide, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Since elderly patients have a higher incidence of renal impairment, the dose selection for the elderly should be made on the basis of renal function [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
8.6 Renal Impairment
The use of FIBRICOR should be avoided in patients who have severe renal impairment. Dose reduction is required in patients with mild-to-moderate renal impairment. Monitoring renal function in patients with renal impairment is recommended [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
The use of FIBRICOR has not been evaluated in patients with hepatic impairment [see Contraindications (4)].
There is no specific treatment for overdose with FIBRICOR. General supportive care of the patient is indicated, including monitoring of vital signs and observation of clinical status, should an overdose occur. If indicated, elimination of unabsorbed drug should be achieved by emesis or gastric lavage; usual precautions should be observed to maintain the airway. Because FIBRICOR is highly bound to plasma proteins, hemodialysis should not be considered.
FIBRICOR is a lipid regulating agent available as tablets for oral administration. Each tablet contains 35 mg or 105 mg of fenofibric acid. The chemical name for fenofibric acid is 2-[4-(4-chlorobenzoyl)phenoxy]-2-methylpropanoic acid with the following structural formula:
Fenofibric acid is a white to almost white crystalline powder that is stable under ordinary conditions, and has a melting point of 179 – 183°C. Its empirical formula is C17H15ClO4 and molecular weight 318.75. Fenofibric acid is insoluble in water; its solubility increases with pH in buffered media.
Inactive Ingredients: Each tablet contains copovidone, crospovidone, magnesium stearate and microcrystalline cellulose.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
The effects of fenofibric acid seen in clinical practice have been explained in vivo in transgenic mice and in vitro in human hepatocyte cultures by the activation of peroxisome proliferator activated receptor α (PPARα). Through this mechanism, fenofibric acid increases lipolysis and elimination of triglyceride-rich particles from plasma by activating lipoprotein lipase and reducing production of apoprotein C-III (an inhibitor of lipoprotein lipase activity). The resulting fall in triglycerides produces an alteration in the size and composition of LDL from small, dense particles to large buoyant particles. These larger particles have a greater affinity for cholesterol receptors and are catabolized rapidly. Activation of PPARα also induces an increase in the synthesis of apoproteins A-I, A-II and HDL-cholesterol.
Elevated levels of Total-C, LDL-C, and Apo B, and decreased levels of HDL-C and its transport complex, Apo AI and Apo AII, are risk factors for atherosclerosis. Epidemiologic studies have established that cardiovascular morbidity and mortality vary directly with the levels of Total-C, LDL-C, and TG, and inversely with the level of HDL-C. The independent effect of raising HDL-C or lowering TG on the risk of cardiovascular morbidity and mortality has not been determined.
The absolute bioavailability of FIBRICOR has not been determined. Following oral administration of FIBRICOR in healthy volunteers, median peak plasma levels of fenofibric acid occur by approximately 2.5 hours after administration. Exposure after administration of 3 x 35 mg FIBRICOR tablets is comparable to 1 x 105 mg FIBRICOR tablets.
A food-effect study involving administration of FIBRICOR to healthy volunteers under fasting conditions and with a high-fat meal indicated that the Cmax was decreased by approximately 35% while the AUC remained unchanged. This decrease in exposure is not considered clinically significant, and therefore FIBRICOR can be taken without regards to meals.
The extent and rate of absorption of fenofibric acid after administration of 105 mg FIBRICOR tablets are equivalent to those after administration of 145 mg fenofibrate tablets (TriCor®) under fasted conditions.
Upon multiple dosing of fenofibrate, fenofibric acid steady state is achieved within 9 days. Plasma concentrations of fenofibric acid at steady state are slightly more than double those following a single dose. Serum protein binding was approximately 99% in normal and hyperlipidemic subjects.
Fenofibric acid is primarily conjugated with glucuronic acid and then excreted in urine. A small amount of fenofibric acid is reduced at the carbonyl moiety to a benzhydrol metabolite which is, in turn, conjugated with glucuronic acid and excreted in urine.
In vitro and in vivo metabolism data indicate that fenofibric acid does not undergo oxidative metabolism (e.g. cytochrome P450) to a significant extent. The enzymes CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4 do not play a role in the metabolism of fenofibric acid.
Fenofibric acid is eliminated with a half-life of approximately 20 hours, allowing once-daily dosing.
Geriatrics: In five elderly volunteers 77 – 87 years of age, the oral clearance of fenofibric acid following a single oral dose of fenofibrate was 1.2 L/h, which compares to 1.1 L/h in young adults. This indicates that an equivalent dose of FIBRICOR can be used in elderly subjects with normal renal function, without increasing accumulation of the drug or metabolites [see Use in Specific Populations (8.5)].
Pediatrics: FIBRICOR has not been investigated in adequate and well-controlled trials in pediatric patients.
Race: The influence of race on the pharmacokinetics of fenofibric acid has not been studied, however fenofibric acid is not metabolized by enzymes known for exhibiting inter-ethnic variability.
Renal Impairment: The pharmacokinetics of fenofibric acid were examined in patients with mild, moderate, and severe renal impairment. Patients with severe renal impairment (creatinine clearance [CrCl ≤ 30 mL/min) showed a 2.7-fold increase in exposure for fenofibric acid and increased accumulation of fenofibric acid during chronic dosing compared to that of healthy subjects. Patients with mild (CrCl 50–80 mL/min) to-moderate (CrCl 30–50 mL/min) renal impairment had similar exposure but an increase in the half-life for fenofibric acid compared to that of healthy subjects. Based on these findings, the use of fenofibric acid should be avoided in patients who have severe renal impairment and dose reduction is required in patients with mild-to-moderate renal impairment.
Hepatic Impairment: No pharmacokinetic studies of fenofibric acid have been conducted in patients with hepatic impairment.
Drug-Drug Interactions: An in vitro study using human hepatocytes indicates that fenofibric acid does not induce CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4.
In vitro studies using human liver microsomes indicate that fenofibric acid is not an inhibitor of cytochrome (CYP) P450 isoforms CYP3A4, CYP2D6, CYP2E1, or CYP1A2.
Table 2 describes the effects of co-administered drugs on fenofibric acid systemic exposure. Table 3 describes the effects of co-administered fenofibric acid on exposure to other drugs.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Two dietary carcinogenicity studies have been conducted in rats with fenofibrate. In the first 24-month study, Wistar rats were dosed with fenofibrate at 10, 45, and 200 mg/kg/day, (approximately 0.3, 1, and 6 times the maximum recommended human (MRHD) dose on the basis of mg/sq meter surface area). At a dose of 200 mg/kg/day (6 times the MRHD), the incidence of liver carcinomas was significantly increased in both sexes. A statistically significant increase in pancreatic carcinomas was observed in males at 45, and 200 mg/kg/day (approximately 1, and 6 times the human dose on the basis of mg/sq meter surface area), an increase in pancreatic adenomas and benign testicular interstitial cell tumors was observed in males at a dose that results in exposure to fenofibric acid that is 6 times the human dose. In a second 24-month rat carcinogenicity study in a different strain of rats (Sprague-Dawley), doses of 10 and 60 mg/kg/day (1.2 and 16.5 times the MRHD of fenofibric acid, based upon exposure) produced significant increases in the incidence of pancreatic acinar adenomas in both sexes and increases in testicular interstitial cell tumors in males at 16.5 times the MRHD of fenofibrate (60 mg/kg/day).
A 117-week carcinogenicity study was conducted in rats comparing three drugs: fenofibrate 10 and 60 mg/kg/day (0.3 and 2 times the MRHD of fenofibrate), clofibrate (400 mg/kg/day; 2 times the human dose), and gemfibrozil (250 mg/kg/day; 2 times the human dose) (multiples based on mg/meter2 surface area). Fenofibrate increased pancreatic acinar adenomas in both sexes. Clofibrate increased hepatocellular carcinoma and pancreatic acinar adenomas in males and hepatic neoplastic nodules in females. Gemfibrozil increased hepatic neoplastic nodules in males and females, while all three drugs increased testicular interstitial cell tumors in males.
In a 21-month study in CF-1 mice, fenofibrate 10, 45, and 200 mg/kg/day (approximately 0.2, 0.7, and 3 times the human dose on the basis of mg/sq meter surface area) significantly increased the liver carcinomas in both sexes at doses that result in exposure to fenofibric acid that is 3.7 times the MRHD of fenofibric acid. In a second 18-month study at 10, 60, and 200 mg/kg/day, fenofibrate significantly increased the liver carcinomas in male mice and liver adenomas in female mice at 3 times the MRHD of fenofibrate.
Electron microscopy studies have demonstrated peroxisomal proliferation following fenofibrate administration to the rat. An adequate study to test for peroxisome proliferation in humans has not been done, but changes in peroxisome morphology and numbers have been observed in humans after treatment with other members of the fibrate class when liver biopsies were compared before and after treatment in the same individual.
Fenofibrate has been demonstrated to be devoid of mutagenic potential in the following tests: Ames, mouse lymphoma, chromosomal aberration and unscheduled DNA synthesis in primary rat hepatocytes and in vivo in the mouse micronucleus assay.
Impairment of Fertility
In fertility studies, rats were given oral dietary doses of fenofibrate. Males received 61 days prior to mating and females 15 days prior to mating through weaning which resulted in no adverse effect on fertility at doses up to 300 mg/kg/day (approximately 10 times the MRHD of fenofibrate, based on mg/m2 surface area comparisons).
14 CLINICAL STUDIES
14.1 Severe Hypertriglyceridemia
The effects of fenofibrate on serum triglycerides were studied in two randomized, double-blind, placebo-controlled clinical trials of 147 hypertriglyceridemic patients. Patients were treated for eight weeks under protocols that differed only in that one protocol entered patients with baseline triglyceride (TG) levels of 500 to 1500 mg/dL, and the other TG levels of 350 to 500 mg/dL.
In patients with hypertriglyceridemia and normal cholesterolemia with or without hyperchylomicronemia, treatment with fenofibrate at dosages equivalent to 105 mg of FIBRICOR decreased primarily very low density lipoprotein (VLDL) triglycerides and VLDL cholesterol. Treatment of some with elevated triglycerides often results in an increase of low density lipoprotein (LDL) cholesterol (see Table 4).
14.2 Primary Hyperlipidemia (Heterozygous Familial and Nonfamilial) and Mixed Dyslipidemia
The effects of fenofibrate at doses equivalent to 105 mg of FIBRICOR were assessed from four randomized, placebo-controlled, double-blind, parallel-group studies including patients with the following mean baseline lipid values: Total-C 306.9 mg/dL; LDL-C 213.8 mg/dL; HDL-C 52.3 mg/dL; and triglycerides 191.0 mg/dL. Fenofibrate therapy lowered LDL-C, Total-C, and the LDL-C/HDL-C ratio. Fenofibrate therapy also lowered triglycerides and raised HDL-C (see Table 5).
In a subset of the subjects, measurement of Apo B was conducted. Fenofibrate treatment significantly reduced Apo B from baseline to endpoint as compared with placebo (-25.1% vs. 2.4%, p < 0.0001, n=213 and 143 respectively).
