Multaq Dronedarone DRONEDARONE DRONEDARONE SILICON DIOXIDE CROSPOVIDONE (120 .MU.M) HYPROMELLOSE, UNSPECIFIED LACTOSE MONOHYDRATE MAGNESIUM STEARATE POLOXAMER 407 STARCH, CORN CARNAUBA WAX POLYETHYLENE GLYCOL 6000 TITANIUM DIOXIDE 4142

In patients with symptomatic heart failure and recent decompensation requiring hospitalization or NYHA Class IV heart failure, MULTAQ doubles the risk of death [see Clinical Studies (14.3)]. MULTAQ is contraindicated in patients with symptomatic heart failure with recent decompensation requiring hospitalization or NYHA Class IV heart failure [see Contraindications (4), Warnings and Precautions (5.1)]. In patients with permanent atrial fibrillation, MULTAQ doubles the risk of death, stroke and hospitalization for heart failure [see Clinical Studies (14.4)]. MULTAQ is contraindicated in patients in atrial fibrillation (AF) who will not or cannot be cardioverted into normal sinus rhythm [see Contraindications (4), Warnings and Precautions (5.2)]. WARNING: INCREASED RISK OF DEATH, STROKE AND HEART FAILURE IN PATIENTS WITH DECOMPENSATED HEART FAILURE OR PERMANENT ATRIAL FIBRILLATION See full prescribing information for complete boxed warning. MULTAQ is contraindicated in patients with symptomatic heart failure with recent decompensation requiring hospitalization or NYHA Class IV heart failure. MULTAQ doubles the risk of death in these patients. (4, 5.1, 14.3) MULTAQ is contraindicated in patients in atrial fibrillation (AF) who will not or cannot be cardioverted into normal sinus rhythm. In patients with permanent AF, MULTAQ doubles the risk of death, stroke, and hospitalization for heart failure. (4, 5.2, 14.4)

MULTAQ® is indicated to reduce the risk of hospitalization for atrial fibrillation in patients in sinus rhythm with a history of paroxysmal or persistent atrial fibrillation (AF) [see Clinical Studies (14)]. MULTAQ is an antiarrhythmic drug indicated to reduce the risk of hospitalization for atrial fibrillation (AF) in patients in sinus rhythm with a history of paroxysmal or persistent AF (1, 14).

The recommended dosage of MULTAQ is 400 mg twice daily in adults. MULTAQ should be taken as one tablet with the morning meal and one tablet with the evening meal. Treatment with Class I or III antiarrhythmics (e.g., amiodarone, flecainide, propafenone, quinidine, disopyramide, dofetilide, sotalol) or drugs that are strong inhibitors of CYP3A (e.g., ketoconazole) must be stopped before starting MULTAQ [see Contraindications (4)]. Verify that females of reproductive potential are not pregnant prior to initiating MULTAQ [see Warnings and Precautions (5.10), Use in Specific Populations (8.1, 8.3)]. One tablet of 400 mg twice a day with morning and evening meals (2)

MULTAQ 400 mg tablets are provided as white film-coated tablets for oral administration, oblong-shaped, engraved with a double wave marking on one side and "4142" code on the other side. 400 mg film-coated tablets (3)

MULTAQ is contraindicated in patients with: •Permanent atrial fibrillation (patients in whom normal sinus rhythm will not or cannot be restored) [see Boxed Warning, Warnings and Precautions (5.2)] •Symptomatic heart failure with recent decompensation requiring hospitalization or NYHA Class IV symptoms [see Boxed Warning, Warnings and Precautions (5.1)] •Second or third-degree atrioventricular (AV) block, or sick sinus syndrome (except when used in conjunction with a functioning pacemaker) •Bradycardia <50 bpm •Concomitant use of strong CYP3A inhibitors, such as ketoconazole, itraconazole, voriconazole, cyclosporine, telithromycin, clarithromycin, nefazodone, and ritonavir [see Drug Interactions (7.2)] •Concomitant use of erythromycin [see Clinical Pharmacology (12.3)] •Concomitant use of drugs or herbal products that prolong the QT interval and might increase the risk of torsade de pointes, such as phenothiazine antipsychotics, tricyclic antidepressants, certain oral macrolide antibiotics, and Class I and III antiarrhythmics •Liver or lung toxicity related to the previous use of amiodarone •QTc interval >500 ms or PR interval >280 ms •Severe hepatic impairment •Hypersensitivity to the active substance or to any of the excipients •Permanent AF (patients in whom normal sinus rhythm will not or cannot be restored) (Boxed Warning, 4) •Recently decompensated heart failure requiring hospitalization or Class IV heart failure (Boxed Warning, 4) •Second or third-degree atrioventricular (AV) block or sick sinus syndrome (except when used in conjunction with a functioning pacemaker) (4) •Bradycardia <50 bpm (4) •Concomitant use of a strong CYP3A inhibitor (4) •Concomitant use of erythromycin (4) •Concomitant use of drugs or herbal products that prolong the QT interval and may induce torsade de pointes (4) •Liver or lung toxicity related to the previous use of amiodarone (4) •QTc interval >500 ms or PR interval >280 ms (4) •Severe hepatic impairment (4) •Hypersensitivity to the active substance or to any of the excipients (4)

•Determine cardiac rhythm at least once every 3 months. If AF is detected discontinue MULTAQ or cardiovert. (5.2) •Ensure appropriate antithrombotic therapy prior to and throughout MULTAQ use. (5.3) •Liver injury: If hepatic injury is suspected, discontinue MULTAQ. (5.5) •If pulmonary toxicity is confirmed, discontinue treatment. (5.6) •Hypokalemia and hypomagnesemia: Maintain potassium and magnesium levels within the normal range. (5.7) •Renal impairment: Monitor renal function periodically. (5.9) •Embryofetal Toxicity: Based on animal data, MULTAQ may cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception while using MULTAQ. (5.10)

MULTAQ is contraindicated in patients with NYHA Class IV heart failure or symptomatic heart failure with recent decompensation requiring hospitalization because it doubles the risk of death.

MULTAQ doubles the risk of cardiovascular death (largely arrhythmic) and heart failure events in patients with permanent AF. Patients treated with dronedarone should undergo monitoring of cardiac rhythm no less often than every 3 months. Cardiovert patients who are in atrial fibrillation (if clinically indicated) or discontinue MULTAQ. MULTAQ offers no benefit in subjects in permanent AF.

In a placebo-controlled study in patients with permanent atrial fibrillation, dronedarone was associated with an increased risk of stroke, particularly in the first two weeks of therapy [see Clinical Studies (14.4)]. MULTAQ should only be initiated in patients in sinus rhythm who are receiving appropriate antithrombotic therapy [see Drug Interactions (7.3)].

New onset or worsening of heart failure has been reported during treatment with MULTAQ in the postmarketing setting. In a placebo-controlled study in patients with permanent AF increased rates of heart failure were observed in patients with normal left ventricular function and no history of symptomatic heart failure, as well as those with a history of heart failure or left ventricular dysfunction. Advise patients to consult a physician if they develop signs or symptoms of heart failure, such as weight gain, dependent edema, or increasing shortness of breath. If heart failure develops or worsens and requires hospitalization, discontinue MULTAQ.

Hepatocellular liver injury, including acute liver failure requiring transplant, has been reported in patients treated with MULTAQ in the postmarketing setting. Advise patients treated with MULTAQ to report immediately symptoms suggesting hepatic injury (such as anorexia, nausea, vomiting, fever, malaise, fatigue, right upper quadrant pain, jaundice, dark urine, or itching). Consider obtaining periodic hepatic serum enzymes, especially during the first 6 months of treatment, but it is not known whether routine periodic monitoring of serum enzymes will prevent the development of severe liver injury. If hepatic injury is suspected, promptly discontinue MULTAQ and test serum enzymes, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase, as well as serum bilirubin, to establish whether there is liver injury. If liver injury is found, institute appropriate treatment and investigate the probable cause. Do not restart MULTAQ in patients without another explanation for the observed liver injury.

Cases of interstitial lung disease including pneumonitis and pulmonary fibrosis have been reported in patients treated with MULTAQ in the postmarketing setting [see Adverse Reactions (6.2)]. Onset of dyspnea or non-productive cough may be related to pulmonary toxicity and patients should be carefully evaluated clinically. If pulmonary toxicity is confirmed, MULTAQ should be discontinued.

Hypokalemia or hypomagnesemia may occur with concomitant administration of potassium-depleting diuretics. Potassium levels should be within the normal range prior to administration of MULTAQ and maintained in the normal range during administration of MULTAQ.

MULTAQ is associated with concentration-dependent QTcF interval prolongation (estimated QTcF increase for 400 mg BID with food is 15 ms) [see Clinical Pharmacology (12.2)]. If the QTc interval is >500 ms, discontinue MULTAQ [see Contraindications (4)].

Marked increase in serum creatinine, pre-renal azotemia and acute renal failure, often in the setting of heart failure [see Warnings and Precautions (5.4)] or hypovolemia, have been reported in patients taking MULTAQ. In most cases, these effects appear to be reversible upon drug discontinuation and with appropriate medical treatment. Monitor renal function periodically. Small increases in creatinine levels (about 0.1 mg/dL) following dronedarone treatment initiation have been shown to be a result of inhibition of creatinine's tubular secretion. The elevation has a rapid onset, reaches a plateau after 7 days and is reversible after discontinuation.

Based on animal data, MULTAQ may cause fetal harm when administered to a pregnant woman. Dronedarone caused multiple visceral and skeletal malformations in animal reproduction studies when pregnant rats and rabbits were administered dronedarone at doses equivalent to recommended human doses. Advise pregnant women of the potential risk to the fetus. Verify that females of reproductive potential are not pregnant prior to initiating MULTAQ. Advise females of reproductive potential to use effective contraception during treatment with MULTAQ and for 5 days (about 6 half-lives) after the final dose [see Use in Specific Populations (8.1, 8.3)].

The following safety concerns are described elsewhere in the label: •New or worsening heart failure [see Warnings and Precautions (5.4)] •Liver Injury [see Warnings and Precautions (5.5)] •Pulmonary toxicity [see Warnings and Precautions (5.6)] •Hypokalemia and hypomagnesemia with potassium-depleting diuretics [see Warnings and Precautions (5.7)] •QT prolongation [see Warnings and Precautions (5.8)] Most common adverse reactions (≥2%) are diarrhea, nausea, abdominal pain, vomiting, dyspepsia, bradycardia, skin issues (rashes, pruritus, eczema, dermatitis, dermatitis allergic), and asthenia (6) To report SUSPECTED ADVERSE REACTIONS, contact sanofi-aventis U.S. LLC at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

The safety evaluation of dronedarone 400 mg twice daily in patients with AF or AFL is based on 5 placebo-controlled studies, ATHENA, EURIDIS, ADONIS, ERATO and DAFNE. In these studies, a total of 6285 patients were randomized and treated, 3282 patients with MULTAQ 400 mg twice daily, and 2875 with placebo. The mean exposure across studies was 12 months. In ATHENA, the maximum follow-up was 30 months. In clinical trials, premature discontinuation because of adverse reactions occurred in 11.8% of the dronedarone-treated patients and in 7.7% of the placebo-treated group. The most common reasons for discontinuation of therapy with MULTAQ were gastrointestinal disorders (3.2% vs 1.8% in the placebo group) and QT prolongation (1.5% vs 0.5% in the placebo group). The most frequent adverse reactions observed with MULTAQ 400 mg twice daily in the 5 studies were diarrhea, nausea, abdominal pain, vomiting, and asthenia. Table 1 displays adverse reactions more common with dronedarone 400 mg twice daily than with placebo in AF or AFL patients, presented by system organ class and by decreasing order of frequency. Adverse laboratory and ECG effects are presented separately in Table 2.

Assessment of demographic factors such as gender or age on the incidence of treatment-emergent adverse events did not suggest an excess of adverse events in any particular subgroup. In randomized clinical trials of patients with paroxysmal or persistent atrial fibrillation, one case of torsade de pointes was reported in patients treated with MULTAQ (2301 patients) versus no cases of torsade de pointes in patients treated with placebo (2327) in the ATHENA study. No cases of torsade de pointes were reported in patients treated with MULTAQ (828 patients) or placebo (409 patients) in the EURIDIS and ADONIS studies [see Clinical Studies (14)].

The following adverse reactions have been identified during postapproval use of MULTAQ. Because these reactions are reported voluntarily from a population of an unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Cardiac: New or worsening heart failure [see Warnings and Precautions (5.4)] Atrial flutter with 1:1 atrioventricular conduction has been reported very rarely. Hepatic: Liver injury [see Warnings and Precautions (5.5)] Respiratory: Interstitial lung disease including pneumonitis and pulmonary fibrosis [see Warnings and Precautions (5.6)] Immune: Anaphylactic reactions including angioedema Vascular: Vasculitis, including leukocytoclastic vasculitis

Dronedarone is metabolized by CYP3A and is a moderate inhibitor of CYP3A and CYP2D6 and has potentially important pharmacodynamic interactions (7) •Class I or III antiarrhythmics: Contraindicated. (4, 7.1) •Digoxin: Consider discontinuation or halve dose of digoxin before treatment and monitor digoxin levels. (7.1, 7.3) •Calcium channel blockers (CCB): Initiate CCB with low dose and increase after ECG verification of tolerability. (7.1, 7.2, 7.3) •Beta-blockers: May provoke excessive bradycardia. Initiate with low dose and increase after ECG verification of tolerability. (7.1, 7.3) •CYP3A inducers: Avoid concomitant use. (7.2) •Grapefruit juice: Avoid concomitant use. (7.2) •Statins: Avoid simvastatin doses greater than 10 mg daily. Follow label recommendations for concomitant use of other statins with a CYP3A and P-gp inhibitor like dronedarone. (7.3) •CYP3A substrates with a narrow therapeutic index (e.g., sirolimus and tacrolimus): Monitor and adjust dosage of concomitant drug as needed when used with MULTAQ. (7.3) •Warfarin: Monitor INR after initiating dronedarone in patients taking warfarin. (7.3)

Drugs Prolonging the QT Interval (Inducing Torsade de Pointes) Coadministration of drugs prolonging the QT interval (such as certain phenothiazines, tricyclic antidepressants, certain macrolide antibiotics, and Class I and III antiarrhythmics) is contraindicated because of the potential risk of torsade de pointes–type ventricular tachycardia [see Contraindications (4), Clinical Pharmacology (12.3)].

Digoxin In the ANDROMEDA (patients with recently decompensated heart failure) and PALLAS (patients with permanent AF) trials baseline use of digoxin was associated with an increased risk of arrhythmic or sudden death in dronedarone-treated patients compared to placebo. In patients not taking digoxin, no difference in risk of sudden death was observed in the dronedarone versus placebo groups [see Clinical Studies (14.3)]. Digoxin can potentiate the electrophysiologic effects of dronedarone (such as decreased AV-node conduction). Dronedarone increases exposure to digoxin [see Drug Interactions (7.3), Clinical Pharmacology (12.3)]. Consider discontinuing digoxin. If digoxin treatment is continued, halve the dose of digoxin, monitor serum levels closely, and observe for toxicity.

Calcium Channel Blockers Calcium channel blockers with depressant effects on the sinus and AV nodes could potentiate dronedarone's effects on conduction. Give a low dose of calcium channel blockers initially and increase only after ECG verification of good tolerability [see Drug Interactions (7.3), Clinical Pharmacology (12.3)].

Beta-Blockers In clinical trials, bradycardia was more frequently observed when dronedarone was given in combination with beta-blockers. Give a low dose of beta-blockers initially, and increase only after ECG verification of good tolerability [see Drug Interactions (7.3), Clinical Pharmacology (12.3)].

Ketoconazole and Other Potent CYP3A Inhibitors Concomitant use of ketoconazole as well as other potent CYP3A inhibitors such as itraconazole, voriconazole, ritonavir, clarithromycin, and nefazodone is contraindicated because exposure to dronedarone is significantly increased [see Contraindications (4), Clinical Pharmacology (12.3)].

Grapefruit Juice Patients should avoid grapefruit juice beverages while taking MULTAQ because exposure to dronedarone is significantly increased [see Clinical Pharmacology (12.3)].

Rifampin and Other CYP3A Inducers Avoid rifampin or other CYP3A inducers such as phenobarbital, carbamazepine, phenytoin, and St. John's wort because they decrease exposure to dronedarone significantly [see Clinical Pharmacology (12.3)].

Calcium Channel Blockers Verapamil and diltiazem are moderate CYP3A inhibitors and increase dronedarone exposure. Give a low dose of calcium channel blockers initially and increase only after ECG verification of good tolerability [see Drug Interactions (7.3), Clinical Pharmacology (12.3)].

Simvastatin Dronedarone increased simvastatin/simvastatin acid exposure. Avoid doses greater than 10 mg once daily of simvastatin [see Clinical Pharmacology (12.3)].

Other Statins Because of multiple mechanisms of interaction with statins (CYPs and transporters), follow statin label recommendations for use with CYP3A and P-gp inhibitors such as dronedarone.

Calcium Channel Blockers Dronedarone increased the exposure of calcium channel blockers (verapamil, diltiazem or nifedipine). Give a low dose of calcium channel blockers initially and increase only after ECG verification of good tolerability [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].

Sirolimus, Tacrolimus, and Other CYP3A Substrates with Narrow Therapeutic Range Dronedarone can increase plasma concentrations of tacrolimus, sirolimus, and other CYP3A substrates with a narrow therapeutic range when given orally. Monitor plasma concentrations and adjust dosage appropriately.

Beta-Blockers and Other CYP2D6 Substrates Dronedarone increased the exposure of propranolol and metoprolol. Give low doses of beta-blockers initially, and increase only after ECG verification of good tolerability. Other CYP2D6 substrates, including other beta-blockers, tricyclic antidepressants, and selective serotonin reuptake inhibitors (SSRIs) may have increased exposure upon coadministration with dronedarone [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].

P-glycoprotein Substrates

Digoxin Dronedarone increased digoxin exposure by inhibiting the P-gp transporter. Consider discontinuing digoxin. If digoxin treatment is continued, halve the dose of digoxin, monitor serum levels closely, and observe for toxicity [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].

Dabigatran Dronedarone increases dabigatran plasma exposures by inhibiting the P-gp transporter [see Clinical Pharmacology (12.3)]. In patients with moderate renal impairment (CrCL 30–50 mL/min), reduce the dose of dabigatran to 75 mg twice daily when concomitantly administered with dronedarone. In patients with severe renal impairment (CrCL 15–30 mL/min), concomitant use of dronedarone with dabigatran should be avoided.

Warfarin When coadministered with dronedarone exposure to S-warfarin was slightly higher than when warfarin was administered alone. There were no clinically significant increases in INR [see Clinical Pharmacology (12.3)]. More patients experienced clinically significant INR elevations (≥5) usually within 1 week after starting dronedarone versus placebo in patients taking oral anticoagulants in ATHENA. However, no excess risk of bleeding was observed in the dronedarone group. Postmarketing cases of increased INR with or without bleeding events have been reported in warfarin-treated patients initiated on dronedarone. Monitor INR after initiating dronedarone in patients taking warfarin.

•Lactation: Do not breastfeed (8.2)

Risk Summary MULTAQ may cause fetal harm when administered to a pregnant woman. In animal studies, dronedarone administered to pregnant rats and rabbits during the period of organogenesis caused multiple visceral (rats) and skeletal malformations (rats and rabbits) when administered at doses equivalent to or lower than the maximum recommended human dose (MRHD) (see Data). There are no available data on dronedarone use in pregnant women to evaluate for a drug-associated risk of major birth defects or miscarriage or other adverse maternal or fetal outcomes. Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal data When pregnant rats in embryofetal development studies received dronedarone at oral doses greater than or equal to the MRHD (on a mg/m2 basis) during organogenesis (gestational days 6 to 15) fetuses had increased rates of external, visceral and skeletal malformations (cranioschisis, cleft palate, incomplete evagination of pineal body, brachygnathia, partially fused carotid arteries, truncus arteriosus, abnormal lobation of the liver, partially duplicated inferior vena cava, brachydactyly, ectrodactyly, syndactyly, and anterior and/or posterior club feet). When pregnant rabbits in embryofetal development studies received dronedarone, at a dose approximately half the MRHD (on a mg/m2 basis) during organogenesis (gestational days 6 to 18), fetuses had an increased rate of skeletal abnormalities (anomalous ribcage and vertebrae, pelvic asymmetry) at doses ≥20 mg/kg (the lowest dose tested and approximately half the MRHD on a mg/m2 basis). Actual animal doses: rat (≥80 mg/kg/day); rabbit (≥20 mg/kg)

Risk Summary There are no available data on the presence of dronedarone in human milk, the effects on the breastfed infant, or the effect on milk production. Dronedarone and its metabolites are present in rat milk. During a prenatal and postnatal study in rats, maternal dronedarone administration was associated with minor reduced body-weight gain in the offspring. When a drug is present in animal milk, it is likely that the drug will be present in human milk. Because of the potential for serious adverse reactions in breastfed infants from MULTAQ like the adverse effects in adults, (liver injury, and pulmonary toxicity), advise patients not to breastfeed during treatment with MULTAQ and for 5 days (about 6 half-lives) after the last dose.

MULTAQ may cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)].

Pregnancy Testing Verify that females of reproductive potential are not pregnant prior to initiating MULTAQ.

Contraception Advise female patients of reproductive potential to use effective contraception during treatment with MULTAQ and for 5 days after the final dose.

Safety and efficacy in children below the age of 18 years have not been established.

More than 4500 patients with AF or AFL aged 65 years or above were included in the MULTAQ clinical program (of whom more than 2000 patients were 75 years or older). Efficacy and safety were similar in elderly and younger patients.

Patients with renal impairment were included in clinical studies. Because renal excretion of dronedarone is minimal [see Clinical Pharmacology (12.3)], no dosing alteration is needed.

Dronedarone is extensively metabolized by the liver. There is little clinical experience with moderate hepatic impairment and none with severe impairment. No dosage adjustment is recommended for moderate hepatic impairment [see Contraindications (4), Clinical Pharmacology (12.3)].

In the event of overdosage, monitor the patient's cardiac rhythm and blood pressure. Treatment should be supportive and based on symptoms. It is not known whether dronedarone or its metabolites can be removed by dialysis (hemodialysis, peritoneal dialysis or hemofiltration). There is no specific antidote available.

Dronedarone HCl is a benzofuran derivative with the following chemical name: N-{2-butyl-3-[4-(3-dibutylaminopropoxy)benzoyl]benzofuran-5-yl} methanesulfonamide, hydrochloride. Dronedarone HCl is a white fine powder that is practically insoluble in water and freely soluble in methylene chloride and methanol. Its empirical formula is C31H44N2O5 S, HCl with a relative molecular mass of 593.2. Its structural formula is: MULTAQ is provided as tablets for oral administration. Each tablet of MULTAQ contains 400 mg of dronedarone (expressed as base). The inactive ingredients are:  Core of the tablets: Colloidal silicon dioxide, crospovidone, hypromellose, lactose monohydrate, magnesium stearate, poloxamer 407, starch.  Coating/polishing of the tablets: Carnauba wax, hypromellose, polyethylene glycol 6000, titanium dioxide. Chemical Structure

The mechanism of action of dronedarone is unknown. Dronedarone has antiarrhythmic properties belonging to all four Vaughan-Williams classes, but the contribution of each of these activities to the clinical effect is unknown.

Electrophysiological Effects The effect of dronedarone on 12-lead ECG parameters was investigated in healthy subjects following repeated oral doses up to 1600 mg twice daily for 10 days. Concentration-dependent increases in QTcF and PR were observed and the estimated increases for 400 mg BID with food are 15 and 12 ms, respectively. The contribution of dronedarone and the N-debutyl metabolite to observed changes is unknown.

DAFNE Study DAFNE was a dose-response study in patients with recurrent AF, evaluating the effect of dronedarone in comparison with placebo in maintaining sinus rhythm. The doses of dronedarone in this study were 400, 600, and 800 mg twice a day. In this small study, doses above 400 mg were not more effective and were less well tolerated.

Dronedarone is extensively metabolized and has low systemic bioavailability; its bioavailability is increased by meals. Its elimination half-life is 13 to 19 hours.

Absorption Because of presystemic first pass metabolism the absolute bioavailability of dronedarone without food is low, about 4%. It increases to approximately 15% when dronedarone is administered with a high fat meal. After oral administration in fed conditions, peak plasma concentrations of dronedarone and the main circulating active metabolite (N-debutyl metabolite) are reached within 3 to 6 hours. After repeated administration of 400 mg twice daily, steady state is reached within 4 to 8 days of treatment and the mean accumulation ratio for dronedarone ranges from 2.6 to 4.5. The steady-state Cmax and exposure of the main N-debutyl metabolite is similar to that of the parent compound. The pharmacokinetics of dronedarone and its N-debutyl metabolite both deviate moderately from dose proportionality: a doubling in dose results in approximately 2.5 to 3.0-fold the Cmax and AUC.

Distribution The in vitro plasma protein binding of dronedarone and its N-debutyl metabolite is >98% and not saturable. Both compounds bind mainly to albumin. After intravenous (IV) administration the volume of distribution at steady state is about 1400 L.

Metabolism Dronedarone is extensively metabolized, mainly by CYP3A. The initial metabolic pathway includes N-debutylation to form the active N-debutyl metabolite, oxidative deamination to form the inactive propanoic acid metabolite, and direct oxidation. The metabolites undergo further metabolism to yield over 30 uncharacterized metabolites. Monoamine oxidases contribute partially to the metabolism of the active metabolite of dronedarone.

Excretion/Elimination In a mass balance study with orally administered dronedarone (14C-labeled) approximately 6% of the labeled dose was excreted in urine, mainly as metabolites (no unchanged compound excreted in urine), and 84% was excreted in feces, mainly as metabolites. Dronedarone and its N-debutyl active metabolite accounted for less than 15% of the resultant radioactivity in the plasma. After IV administration the plasma clearance of dronedarone ranges from 130 to 150 L/h. The elimination half-life of dronedarone ranges from 13 to 19 hours.

Special Populations

Gender Dronedarone exposures are on average 30% higher in females than in males.

Race Pharmacokinetic differences related to race were not formally assessed. However, based on a cross study comparison, following single dose administration (400 mg), Asian males (Japanese) have about twice the exposure than Caucasian males. The pharmacokinetics of dronedarone in other races has not been assessed.

Elderly Of the total number of subjects in clinical studies of dronedarone, 73% were 65 years of age and over and 34% were 75 and over. In patients aged 65 years old and above, dronedarone exposures are 23% higher than in patients less than 65 years old [see Use in Specific Populations (8.5)].

Hepatic impairment In subjects with moderate hepatic impairment, the mean dronedarone exposure increased by 30% relative to subjects with normal hepatic function and the mean exposure of the N-debutyl metabolite decreased by about 50%. Pharmacokinetic data were significantly more variable in subjects with moderate hepatic impairment. The effect of severe hepatic impairment on the pharmacokinetics of dronedarone was not assessed [see Contraindications (4)].

Renal impairment Consistent with the low renal excretion of dronedarone, no pharmacokinetic difference was observed in subjects with mild or moderate renal impairment compared to subjects with normal renal function [see Use in Specific Populations (8.6)]. No pharmacokinetic difference was observed in patients with mild to severe renal impairment in comparison with patients with normal renal function.

Drug Interactions Dronedarone is metabolized primarily by CYP3A and is a moderate inhibitor of CYP3A and CYP2D6. Dronedarone has no significant potential to inhibit CYP1A2, CYP2C9, CYP2C19, CYP2C8 and CYP2B6. It has the potential to inhibit P-glycoprotein (P-gp) transport. Dronedarone inhibits in vivo the tubular secretion of creatinine a substrate of the organic cation transporter (OCT2) [see Warnings and Precautions (5.9)]. In vitro dronedarone and the metabolites SR35021 and SR90154 show no significant potential to inhibit the organic anion transporters OAT1 and OAT3 or the organic cation transporter OCT1. However, in vitro data indicate that SR90154 is likely to inhibit the organic anion transporting polypeptides (OATP1B1, OATP1B3) in vivo. Pharmacokinetic measures indicating the magnitude of these interactions are presented in Figure 1 (impact of coadministered drugs on dronedarone) and Figure 2 (impact of dronedarone on coadministered drugs). Figure 1: The Impact of Coadministered Drugs on the Pharmacokinetics of Dronedarone and Recommendations for Dronedarone Coadministration or Dose Adjustment Figure 2: The Impact of Dronedarone on Coadministered Drugs and Recommendations for Dose Adjustment of Coadministered Drug Figure 1 Figure 2

In studies in which dronedarone was administered to rats and mice for up to 2 years at doses of up to 70 mg/kg/day and 300 mg/kg/day, respectively, there was an increased incidence of histiocytic sarcomas in dronedarone-treated male mice (300 mg/kg/day or 5 × the maximum recommended human dose based on AUC comparisons), mammary adenocarcinomas in dronedarone-treated female mice (300 mg/kg/day or 8 × MRHD based on AUC comparisons) and hemangiomas in dronedarone-treated male rats (70 mg/kg/day or 5 × MRHD based on AUC comparisons). Dronedarone did not demonstrate genotoxic potential in the in vivo mouse micronucleus test, the Ames bacterial mutation assay, the unscheduled DNA synthesis assay, or an in vitro chromosomal aberration assay in human lymphocytes. S-9 processed dronedarone, however, was positive in a V79 transfected Chinese hamster V79 assay. In fertility studies conducted with female rats, dronedarone given prior to breeding and implantation caused an increase in irregular estrus cycles and cessation of cycling at doses ≥10 mg/kg (equivalent to 0.12 × the MRHD on a mg/m2 basis). Corpora lutea, implantations and live fetuses were decreased at 100 mg/kg (equivalent to 1.2 × the MRHD on a mg/m2 basis). There were no reported effects on mating behavior or fertility of male rats at doses of up to 100 mg/kg/day.

Dronedarone was teratogenic in rats given oral doses ≥80 mg/kg/day (a dose equivalent to the MRHD on a mg/m2 basis), with fetuses showing external, visceral and skeletal malformations (cranioschisis, cleft palate, incomplete evagination of pineal body, brachygnathia, partially fused carotid arteries, truncus arteriosus, abnormal lobation of the liver, partially duplicated inferior vena cava, brachydactyly, ectrodactyly, syndactyly, and anterior and/or posterior club feet). In rabbits, dronedarone caused an increase in skeletal abnormalities (anomalous ribcage and vertebrae, pelvic asymmetry) at doses ≥20 mg/kg (the lowest dose tested and approximately half the MRHD on a mg/m2 basis).

ATHENA was a multicenter, multinational, double blind, and randomized placebo-controlled study of dronedarone in 4628 patients with a recent history of AF/AFL who were in sinus rhythm or who were to be converted to sinus rhythm. The objective of the study was to determine whether dronedarone could delay death from any cause or hospitalization for cardiovascular reasons. Initially patients were to be ≥70 years old, or <70 years old with at least one risk factor (including hypertension, diabetes, prior cerebrovascular accident, left atrial diameter ≥50 mm or LVEF <0.40). The inclusion criteria were later changed such that patients were to be ≥75 years old, or ≥70 years old with at least one risk factor. Patients had to have both AF/AFL and sinus rhythm documented within the previous 6 months. Patients could have been in AF/AFL or in sinus rhythm at the time of randomization, but patients not in sinus rhythm were expected to be either electrically or chemically converted to normal sinus rhythm after anticoagulation. Subjects were randomized and treated for up to 30 months (median follow-up: 22 months) with either MULTAQ 400 mg twice daily (2301 patients) or placebo (2327 patients), in addition to conventional therapy for cardiovascular diseases that included beta-blockers (71%), ACE inhibitors or angiotensin II receptor blockers (ARBs) (69%), digoxin (14%), calcium antagonists (14%), statins (39%), oral anticoagulants (60%), aspirin (44%), other chronic antiplatelet therapy (6%) and diuretics (54%). The primary endpoint of the study was the time to first hospitalization for cardiovascular reasons or death from any cause. Time to death from any cause, time to first hospitalization for cardiovascular reasons, and time to cardiovascular death and time to all causes of death were also explored. Patients ranged in age from 23 to 97 years; 42% were 75 years old or older. Forty-seven percent (47%) of patients were female and a majority was Caucasian (89%). Seventy-one percent (71%) of those enrolled had no history of heart failure. The median ejection fraction was 60%. Twenty-nine percent (29%) of patients had heart failure, mostly NYHA class II (17%). The majority had hypertension (86%) and structural heart disease (60%). Results are shown in Table 3. MULTAQ reduced the combined endpoint of cardiovascular hospitalization or death from any cause by 24.2% when compared to placebo. This difference was entirely attributable to its effect on cardiovascular hospitalization, principally hospitalization related to AF. Other endpoints, death from any cause and first hospitalization for cardiovascular reasons, are shown in Table 3. Secondary endpoints count all first events of a particular type, whether or not they were preceded by a different type of event.

The Kaplan-Meier cumulative incidence curves showing the time to first event are displayed in Figure 3. The event curves separated early and continued to diverge over the 30-month follow-up period. Figure 3: Kaplan-Meier Cumulative Incidence Curves from Randomization to First Cardiovascular Hospitalization or Death from Any Cause Reasons for hospitalization included major bleeding (1% in both groups), syncope (1% in both groups), and ventricular arrhythmia (<1% in both groups). The reduction in cardiovascular hospitalization or death from any cause was generally consistent in all subgroups based on baseline characteristics or medications (ACE inhibitors or ARBs; beta-blockers, digoxin, statins, calcium channel blockers, diuretics) (see Figure 4).

In EURIDIS and ADONIS, a total of 1237 patients in sinus rhythm with a prior episode of AF or AFL were randomized in an outpatient setting and treated with either MULTAQ 400 mg twice daily (n=828) or placebo (n=409) on top of conventional therapies (including oral anticoagulants, beta-blockers, ACE inhibitors or ARBs, chronic antiplatelet agents, diuretics, statins, digoxin, and calcium channel blockers). Patients had at least one ECG-documented AF/AFL episode during the 3 months prior to study entry but were in sinus rhythm for at least one hour. Patients ranged in age from 20 to 88 years, with the majority being Caucasian (97%), male (70%) patients. The most common comorbidities were hypertension (56.8%) and structural heart disease (41.5%), including coronary heart disease (21.8%). Patients were followed for 12 months. In the pooled data from EURIDIS and ADONIS as well as in the individual trials, dronedarone delayed the time to first recurrence of AF/AFL (primary endpoint), lowering the risk of first AF/AFL recurrence during the 12-month study period by about 25%, with an absolute difference in recurrence rate of about 11% at 12 months.

Patients recently hospitalized with symptomatic heart failure and severe left ventricular systolic dysfunction (wall motion index ≤1.2) were randomized to either MULTAQ 400 mg twice daily or matching placebo, with a primary composite end point of all-cause mortality or hospitalization for heart failure. Patients enrolled in ANDROMEDA were predominantly NYHA Class II (40%) and III (57%), and only 25% had AF at randomization. After enrollment of 627 patients and a median follow-up of 63 days, the trial was terminated because of excess mortality in the dronedarone group. Twenty-five (25) patients in the dronedarone group died versus 12 patients in the placebo group (hazard ratio 2.13; 95% CI: 1.07 to 4.25). The main reason for death was worsening heart failure. Baseline digoxin therapy was reported in 6/16 dronedarone patients versus 1/16 placebo patients who died of arrhythmia. In patients without baseline use of digoxin, no excess risk of arrhythmic death was observed in the dronedarone versus placebo groups. There were also excess hospitalizations for cardiovascular reasons in the dronedarone group (71 vs 51 for placebo) [see Boxed Warning, Contraindications (4)].

Patients with permanent AF (AF documented in 2 weeks prior to randomization and at least 6 months prior to randomization in whom cardioversion had failed or was not planned) and additional risk factors for thromboembolism (coronary artery disease, prior stroke or TIA, symptomatic heart failure, LVEF <40%, peripheral arterial occlusive disease, or age >75 with hypertension and diabetes) were randomized to dronedarone 400 mg twice daily or placebo. After enrollment of 3236 patients (placebo=1617 and dronedarone=1619) and a median follow up of 3.7 months for placebo and 3.9 for dronedarone, the study was terminated because of a significant increase in: •Mortality: 25 dronedarone versus 13 placebo (HR, 1.94; CI: 0.99 to 3.79). The majority of deaths in the dronedarone group were classified as arrhythmic/sudden deaths (HR, 3.26; CI: 1.06 to 10.0). Baseline digoxin therapy was reported in 11/13 dronedarone patients who died of arrhythmia. None of the arrhythmic deaths on placebo (4) reported use of digoxin. In patients without baseline use of digoxin, no excess risk of arrhythmic death was observed in the dronedarone versus placebo groups. •Stroke: 23 dronedarone versus 10 placebo (HR, 2.32; CI: 1.11 to 4.88). The increased risk of stroke observed with dronedarone was observed in the first two weeks of therapy (10 dronedarone vs 1 placebo), most of the subjects treated with dronedarone did not have an INR of 2.0 to 3.0 [see Warnings and Precautions (5.3)]. •Hospitalizations for heart failure in the dronedarone group: 43 dronedarone versus 24 placebo (HR, 1.81; CI: 1.10 to 2.99).
