Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    Darifenacin hydrobromide extended-release tablets are a muscarinic antagonist indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency and frequency.

  • 2 DOSAGE AND ADMINISTRATION

    The recommended starting dose of Darifenacin Hydrobromide Extended-Release Tablets is 7.5 mg (base) once daily. Based upon individual response, the dose may be increased to 15 mg (base) once daily, as early as two weeks after starting therapy.

    Darifenacin hydrobromide extended-release tablets should be taken once daily with water. Darifenacin hydrobromide extended-release tablets may be taken with or without food, and should be swallowed whole and not chewed, divided or crushed.

    For patients with moderate hepatic impairment (Child-Pugh B) or when coadministered with potent CYP3A4 inhibitors (for example, ketoconazole, itraconazole, ritonavir, nelfinavir, clarithromycin and nefazodone), the daily dose of darifenacin hydrobromide extended-release tablets should not exceed 7.5 mg (base). Darifenacin hydrobromide extended-release tablets are not recommended for use in patients with severe hepatic impairment (Child-Pugh C) [see Warnings & Precautions ( 5.6) , Drug Interactions ( 7.1) ,Use in Specific Populations ( 8.6) and Clinical Pharmacology ( 12.3) ].

  • 4 CONTRAINDICATIONS

    Darifenacin hydrobromide extended-release tablets are contraindicated in patients with, or at risk for, the following conditions:

    • urinary retention
    • gastric retention, or
    • uncontrolled narrow-angle glaucoma.
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Risk of Urinary Retention

    Darifenacin hydrobromide extended-release tablets should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention.

    5.2 Decreased Gastrointestinal Motility

    Darifenacin hydrobromide extended-release tablets should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention. Darifenacin hydrobromide extended-release tablets, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as severe constipation, ulcerative colitis, and myasthenia gravis.

    5.3 Controlled Narrow-Angle Glaucoma

    Darifenacin hydrobromide extended-release tablets should be used with caution in patients being treated for narrow-angle glau-coma and only where the potential benefits outweigh the risks.

    5.4 Angioedema

    Angioedema of the face, lips, tongue, and/or larynx have been reported with darifenacin. In some cases angioedema occurred after the first dose. Angioedema associated with upper airway swelling may be life threatening. If involvement of the tongue, hypopharynx, or larynx occurs, darifenacin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided.

    5.5 Central Nervous System Effects

    Darifenacin hydrobromide extended-release tablets are associated with anticholinergic central nervous system (CNS) effects [see Adverse Reactions ( 6.2) ]. A variety of CNS anticholinergic effects have been reported, including headache, confusion, hallucinations and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly after beginning treatment or increasing the dose. Advise patients not to drive or operate heavy machinery until they know how darifenacin hydrobromide extended-release tablets effects them. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered.

    5.6 Patients with Hepatic Impairment

    The daily dose of darifenacin hydrobromide extended-release tablets should not exceed 7.5 mg (base) for patients with moderate hepatic impairment (Child-Pugh B). Darifenacin hydrobromide extended-release tablets have not been studied in patients with severe hepatic impairment (Child-Pugh C) and therefore are not recommended for use in this patient population [see DOSAGE AND ADMINISTRATION (2), Use in Specific Populations ( 8.6) and Clinical Pharmacology ( 12.3) ].

  • 6 ADVERSE REACTIONS

    6.1 Clinical Trials 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 practice.

    The safety of darifenacin hydrobromide extended-release tablets was evaluated in controlled clinical trials in a total of 8,830 patients, 6,001 of whom were treated with darifenacin hydrobromide extended-release tablets. Of this total, 1,069 patients participated in three, 12-week, randomized, placebo-controlled, fixed-dose efficacy and safety studies (Studies 1, 2 and 3). Of this total, 337 and 334 patients received darifenacin hydrobromide extended-release tablets 7.5 mg (base) daily and 15 mg (base) daily, respectively. In all long-term trials combined, 1,216 and 672 patients received treatment with darifenacin hydrobromide extended-release tablets for at least 24 and 52 weeks, respectively.

    In Studies 1, 2 and 3 combined, the serious adverse reactions to darifenacin hydrobromide extended-release tablets were urinary retention and constipation.

    In Studies 1, 2 and 3 combined, dry mouth leading to study discontinuation occurred in 0 percent, 0.9 percent, and 0 percent of patients treated with darifenacin hydrobromide extended-release tablets 7.5 mg (base) daily, darifenacin hydrobromide extended-release tablets 15 mg (base) daily and placebo, respectively. Constipation leading to study discontinuation occurred in 0.6 percent, 1.2 percent, and 0.3 percent of patients treated with darifenacin hydrobromide extended-release tablets 7.5 mg (base) daily, darifenacin hydrobromide extended-release tablets 15 mg (base) daily and placebo, respectively.

    Table 1 lists the rates of identified adverse reactions, derived from all reported adverse events in 2 percent or more of patients treated with 7.5 mg or 15 mg (base) darifenacin hydrobromide extended-release tablets, and greater than placebo in Studies 1, 2 and 3. In these studies, the most frequently reported adverse reactions were dry mouth and constipation. The majority of the adverse reactions were mild or moderate in severity and most occurred during the first two weeks of treatment.

    6.2 Post Marketing Experience

    The following adverse reactions have been reported during post approval use of darifenacin hydrobromide extended- release tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate frequency or establish a causal relationship to drug exposure.

    Dermatologic: erythema multiforme, interstitial granuloma annulare

    General: hypersensitivity reactions, including angioedema with airway obstruction and anaphylactic reaction

    Central Nervous: confusion, hallucinations and somnolence

    Cardiovascular: palpitations and syncope

  • 7 DRUG INTERACTIONS

    7.1 CYP3A4 Inhibitors

    The systemic exposure of darifenacin from darifenacin hydrobromide extended-release tablets is increased in the presence of CYP3A4 inhibitors. The daily dose of darifenacin hydrobromide extended-release tablets should not exceed 7.5 mg (base) when coadministered with potent CYP3A4 inhibitors (for example, ketoconazole, itraconazole, ritonavir, nelfinavir, clarithromycin and nefazodone). No dosing adjustments are recommended in the presence of moderate CYP3A4 inhibitors (for example, erythromycin, fluconazole, diltiazem and verapamil) [see DOSAGE AND ADMINISTRATION ( 2) and Clinical Pharmacology ( 12.3) ].

    7.2 CYP2D6 Inhibitors

    No dosing adjustments are recommended in the presence of CYP2D6 inhibitors (for example, paroxetine, fluoxetine, quinidine and duloxetine) [see Clinical Pharmacology ( 12.3) ].

    7.3 CYP2D6 Substrates

    Caution should be taken when darifenacin hydrobromide extended-release tablets are used concomitantly with medications that are predominantly metabolized by CYP2D6 and which have a narrow therapeutic window (for example, flecainide, thioridazine and tricyclic antidepressants) [see Clinical Pharmacology ( 12.3) ].

    7.4 CYP3A4 Substrates

    Darifenacin (30 mg daily) did not have a significant impact on midazolam (7.5 mg) pharmacokinetics [see Clinical Pharmacology ( 12.3) ].

    7.5 Combination oral contraceptives

    Darifenacin (10 mg three times daily) had no effect on the pharmacokinetics of the combination oral contraceptives containing levonorgestrel and ethinyl estradiol [see Clinical Pharmacology ( 12.3) ].

    7.6 Warfarin

    Darifenacin had no significant effect on prothrombin time when a single dose of warfarin 30 mg was coadministered with darifenacin (30 mg daily) at steady-state. Standard therapeutic prothrombin time monitoring for warfarin should be continued.

    7.7 Digoxin

    Darifenacin (30 mg daily) did not have a clinically relevant effect on the pharmacokinetics of digoxin (0.25 mg) at steady-state. Routine therapeutic drug monitoring for digoxin should be continued [see Clinical Pharmacology ( 12.3) ].

    7.8 Other Anticholinergic Agents

    The concomitant use of darifenacin hydrobromide extended-release tablets with other anticholinergic agents may increase the frequency and/or severity of dry mouth, constipation, blurred vision and other anticholinergic pharmacological effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to effects on gastrointestinal motility.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category C

    There are no studies of darifenacin in pregnant women.

    Darifenacin was not teratogenic in rats and rabbits at plasma exposures of free drug (via AUC) up to 59 times and 28 times, respectively (doses up to 50 and 30 mg/kg/day, respectively) the maximum recommended human dose [MRHD] of 15 mg. At approximately 59 times the MRHD in rats, there was a delay in the ossification of the sacral and caudal vertebrae which was not observed at approximately 13 times the AUC. Dystocia was observed in dams at approximately 17 times the AUC (10 mg/kg/day). Slight developmental delays were observed in pups at this dose. At five times the AUC (3 mg/kg/day), there were no effects on dams or pups. In rabbits, an exposure approximately 28 times (30 mg/kg/day) the MRHD of darifenacin was shown to increase post-implantation loss, with a no effect level at nine times (10 mg/kg/day) the AUC at the MRHD. Dilated ureter and/or kidney pelvis was also observed in offspring at this dose along with urinary bladder dilation consistent with the pharmacological action of darifenacin, with one case observed at nine times (10 mg/kg/day). No effect was observed at approximately 2.8 times (3 mg/kg/day) the AUC at the MRHD.

    Because animal reproduction studies are not always predictive of human response, darifenacin hydrobromide extended-release tablets should be used during pregnancy only if the benefit to the mother outweighs the potential risk to the fetus.

    8.3 Nursing Mothers

    Darifenacin is excreted into the milk of rats. It is not known whether darifenacin is excreted into human milk and therefore caution should be exercised before darifenacin hydrobromide extended-release tablets are administered to a nursing woman.

    8.4 Pediatric Use

    The safety and effectiveness of darifenacin hydrobromide extended-release tablets in pediatric patients have not been established.

    8.5 Geriatric Use

    In the fixed-dose, placebo-controlled, clinical studies, 30 percent of patients treated with darifenacin hydrobromide extended- release tablets were over 65 years of age. No overall differences in safety or efficacy were observed between patients over 65 years (n = 207) and younger patients <65 years (n = 464). No dose adjustment is recommended for elderly patients [see Clinical Pharmacology ( 12.3) and CLINICAL STUDIES ( 14) ].

    8.6 Hepatic Impairment

    Subjects with severe hepatic impairment (Child-Pugh C) have not been studied, therefore darifenacin hydrobromide extended- release tablets are not recommended for use in these patients [see DOSAGE AND ADMINISTRATION ( 2) and Warnings and Precautions ( 5.6) ]. The daily dose of darifenacin hydrobromide extended-release tablets should not exceed 7.5 mg (base) once daily for patients with moderate hepatic impairment (Child-Pugh B) [see DOSAGE AND ADMINISTRATION ( 2) and Warnings and Precautions ( 5.6) ]. After adjusting for plasma protein binding, unbound darifenacin exposure was estimated to be 4.7-fold higher in subjects with moderate hepatic impairment than subjects with normal hepatic function. No dose adjustment is recommended for patients with mild hepatic impairment (Child-Pugh A).

    8.7 Renal Impairment

    A study of subjects with varying degrees of renal impairment (creatinine clearance between 10 and 136 mL/min) demonstrated no clear relationship between renal function and darifenacin clearance. No dose adjustment is recommended for patients with renal impairment [see Clinical Pharmacology ( 12.3) ].

    8.8 Gender

    No dose adjustment is recommended based on gender [see Clinical Pharmacology ( 12.3) and CLINICAL STUDIES ( 14) ].

  • 10 OVERDOSAGE

    Overdosage with antimuscarinic agents, including darifenacin hydrobromide extended-release tablets, can result in severe antimuscarinic effects. Treatment should be symptomatic and supportive. In the event of overdosage, ECG monitoring is recommended. Darifenacin hydrobromide extended-release tablets have been administered in clinical trials at doses up to 75 mg (five times the maximum therapeutic dose) and signs of overdose were limited to abnormal vision.

  • 11 DESCRIPTION

    Chemically, darifenacin hydrobromide is (S)-2-{1-[2-(2,3-dihydrobenzofuran-5-yl)ethyl]-3-pyrrolidinyl}-2,2-diphenylacetamide hydrobromide. The empirical formula of darifenacin hydrobromide is C 28H 30N 2O 2·HBr.

    The structural formula is:

    Chemical Structure: Darifenacin Hydrobromide

    Darifenacin hydrobromide is a white to almost white, crystalline powder, with a molecular weight of 507.5.

    Darifenacin hydrobromide extended-release tablets are a once-a-day extended-release tablet and contain the following inactive ingredients: dibasic calcium phosphate anhydrous, hypromellose, lactose monohydrate, magnesium stearate, polyvinyl alcohol, polyethylene glycol, talc, titanium dioxide. The 7.5 mg tablet also contains D&C yellow No. 10 Aluminum Lake and FD&C yellow No. 6/sunset yellow FCF Aluminum Lake.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Darifenacin is a competitive muscarinic receptor antagonist. Muscarinic receptors play an important role in several major cholinergically mediated functions, including contractions of the urinary bladder smooth muscle and stimulation of salivary secretion.

    In vitro studies using human recombinant muscarinic receptor subtypes show that darifenacin has greater affinity for the M 3 receptor than for the other known muscarinic receptors (9- and 12-fold greater affinity for M 3 compared to M 1 and M 5, respectively, and 59-fold greater affinity for M 3 compared to both M 2 and M 4). M 3 receptors are involved in contraction of human bladder and gastrointestinal smooth muscle, saliva production, and iris sphincter function. Adverse drug effects such as dry mouth, constipation and abnormal vision may be mediated through effects on M 3 receptors in these organs.

    12.2 Pharmacodynamics

    In three cystometric studies performed in patients with involuntary detrusor contractions, increased bladder capacity was demon-strated by an increased volume threshold for unstable contractions and diminished frequency of unstable detrusor contractions after darifenacin hydrobromide extended-release tablets treatment. These findings are consistent with an antimuscarinic action on the urinary bladder.

    Electrophysiology

    The effect of six-day treatment of 15 mg and 75 mg darifenacin hydrobromide extended-release tablets on QT/QTc interval was evaluated in a multiple-dose, double-blind, randomized, placebo- and active-controlled (moxifloxacin 400 mg) parallel-arm design study in 179 healthy adults (44 percent male, 56 percent female) aged 18 to 65. Subjects included 18 percent poor metabolizer (PMs) and 82 percent extensive metabolizer (EMs). The QT interval was measured over a 24-hour period both predosing and at steady-state. The 75 mg darifenacin hydrobromide extended-release tablets dose was chosen because this achieves exposure similar to that observed in CYP2D6 poor metabolizers administered the highest recommended dose (15 mg) of darifenacin in the presence of a potent CYP3A4 inhibitor. At the doses studied, darifenacin hydrobromide extended-release tablets did not result in QT/QTc interval prolongation at any time during the steady-state, while moxifloxacin treatment resulted in a mean increase from baseline QTcF of about 7.0 msec when compared to placebo. In this study, darifenacin 15 mg and 75 mg doses demonstrated a mean heart rate change of 3.1 and 1.3 bpm, respectively, when compared to placebo. However, in the clinical efficacy and safety studies, the change in median HR following treatment with darifenacin hydrobromide extended-release tablets was no different from placebo.

    12.3 Pharmacokinetics

    Absorption

    After oral administration of darifenacin hydrobromide extended-release tablets to healthy volunteers, peak plasma concentrations of darifenacin are reached approximately seven hours after multiple dosing and steady-state plasma concentrations are achieved by the sixth day of dosing. The mean (SD) steady-state time course of darifenacin hydrobromide extended-release tablets 7.5 mg and 15 mg (base) is depicted in Figure 1.

    The mean oral bioavailability of darifenacin hydrobromide extended-release tablets in EMs at steady-state is estimated to be 15 percent and 19 percent for 7.5 mg and 15 mg (base) tablets, respectively.

    Effect of Food

    Following single dose administration of darifenacin hydrobromide extended-release tablets with food, the AUC of darifenacin was not affected, while the C max was increased by 22 percent and T max was shortened by 3.3 hours. There is no effect of food on multiple-dose pharmacokinetics from darifenacin hydrobromide extended-release tablets.

    Distribution

    Darifenacin is approximately 98 percent bound to plasma proteins (primarily to alpha-1-acid-glycoprotein). The steady-state volume of distribution (V ss) is estimated to be 163 L.

    Metabolism

    Darifenacin is extensively metabolized by the liver following oral dosing.

    Metabolism is mediated by cytochrome P450 enzymes CYP2D6 and CYP3A4. The three main metabolic routes are as follows:

    1. monohydroxylation in the dihydrobenzofuran ring;
    2. dihydrobenzofuran ring opening;
    3. N-dealkylation of the pyrrolidine nitrogen.

    The initial products of the hydroxylation and N-dealkylation pathways are the major circulating metabolites but they are unlikely to contribute significantly to the overall clinical effect of darifenacin.

    Variability in Metabolism

    A subset of individuals (approximately 7 percent Caucasians and 2 percent African Americans) are poor metabolizers (PMs) of CYP2D6 metabolized drugs. Individuals with normal CYP2D6 activity are referred to as extensive metabolizers (EMs). The metabolism of darifenacin in PMs will be principally mediated via CYP3A4. The darifenacin ratios (PM versus EM) for C max and AUC following darifenacin 15 mg (base) once daily at steady-state were 1.9 and 1.7, respectively.

    Excretion

    Following administration of an oral dose of 14C-darifenacin solution to healthy volunteers, approximately 60 percent of the radioactivity was recovered in the urine and 40 percent in the feces. Only a small percentage of the excreted dose was unchanged darifenacin (3 percent). Estimated darifenacin clearance is 40 L/h for EMs and 32 L/h for PMs. The elimination half-life of darifenacin following chronic dosing is approximately 13 to 19 hours.

    Drug-Drug Interactions

    Effects of Other Drugs on Darifenacin

    Darifenacin metabolism is primarily mediated by the cytochrome P450 enzymes CYP2D6 and CYP3A4. Therefore, inducers of CYP3A4 or inhibitors of either of these enzymes may alter darifenacin pharmacokinetics [see DRUG INTERACTIONS ( 7) ].

    CYP3A4 Inhibitors: In a drug interaction study, when a 7.5 mg (base) once daily dose of darifenacin hydrobromide extended-release tablets was given to steady-state and coadministered with the potent CYP3A4 inhibitor ketoconazole 400 mg, mean darifenacin C max increased to 11.2 ng/mL for EMs (n = 10) and 55.4 ng/mL for one PM subject (n = 1). Mean AUC increased to 143 and 939 ngh/mL for EMs and for one PM subject, respectively. When a 15 mg (base) daily dose of darifenacin hydrobromide extended-release tablets was given with ketoconazole, mean darifenacin C max increased to 67.6 ng/mL and 58.9 ng/mL for EMs (n = 3) and one PM subject (n = 1), respectively. Mean AUC increased to 1110 and 931 ngh/mL for EMs and for one PM subject, respectively [see DOSAGE AND ADMINISTRATION (2) and Drug Interactions ( 7.1) ].

    The mean C max and AUC of darifenacin following 30 mg once daily dosing at steady-state were 128 percent and 95 percent higher, respectively, in the presence of a moderate CYP3A4 inhibitor, erythromycin. Coadministration of fluconazole, a moderate CYP3A4 inhibitor and darifenacin 30 mg once daily at steady-state increased darifenacin C max and AUC by 88 percent and 84 percent, respectively [see Drug Interactions ( 7.1) ].

    The mean C max and AUC of darifenacin following 30 mg once daily at steady-state were 42 percent and 34 percent higher, respectively, in the presence of cimetidine, a mixed CYP P450 enzyme inhibitor.

    CYP2D6 Inhibitors: Darifenacin exposure following 30 mg once daily at steady-state was 33 percent higher in the presence of the potent CYP2D6 inhibitor paroxetine 20 mg [see Drug Interactions ( 7.2) ].

    Effects of Darifenacin on Other Drugs

    In Vitro Studies: Based on in vitro human microsomal studies, darifenacin hydrobromide extended-release tablets are not expected to inhibit CYP1A2 or CYP2C9 at clinically relevant concentrations.

    In Vivo Studies: The potential for clinical doses of darifenacin hydrobromide extended-release tablets to act as inhibitors of CYP2D6 or CYP3A4 substrates was investigated in specific drug interaction studies.

    CYP2D6 Substrates: The mean C max and AUC of imipramine, a CYP2D6 substrate, were increased by 57 percent and 70 percent, respectively, in the presence of steady-state darifenacin 30 mg once daily. The mean C max and AUC of desipramine, the active metabolite of imipramine, were increased by 260 percent [see Drug Interactions ( 7.3) ].

    CYP3A4 Substrates: Darifenacin (30 mg daily) coadministered with a single oral dose of midazolam 7.5 mg resulted in a 17 percent increase in midazolam exposure.

    Combination Oral Contraceptives: Darifenacin (10 mg three times daily) had no effect on the pharmacokinetics of a combination oral contraceptive containing levonorgestrel (0.15 mg) and ethinyl estradiol (0.03 mg).

    Warfarin: Darifenacin had no significant effect on prothrombin time when a single dose of warfarin 30 mg was coadministered with darifenacin (30 mg daily) at steady-state [see Drug Interactions ( 7.6) ].

    Digoxin: Darifenacin (30 mg daily) coadministered with digoxin (0.25 mg) at steady-state resulted in a 16 percent increase in digoxin exposure [see Drug Interactions ( 7.7) ].

    Pharmacokinetics in Special Populations

    Age: A population pharmacokinetic analysis of patient data indicated a trend for clearance of darifenacin to decrease with age (6 percent per decade relative to a median age of 44). Following administration of darifenacin hydrobromide extended-release tablets 15 mg (base) once daily, darifenacin exposure at steady-state was approximately 12 percent to 19 percent higher in volunteers between 45 and 65 years of age compared to younger volunteers aged 18 to 44 years [see Use in Specific Populations ( 8.5) ].

    Pediatric: The pharmacokinetics of darifenacin hydrobromide extended-release tablets has not been studied in the pediatric population [see Use in Specific Populations ( 8.4) ].

    Gender: PK parameters were calculated for 22 male and 25 female healthy volunteers. Darifenacin C max and AUC at steady-state were approximately 57 percent to 79 percent and 61 percent to 73 percent higher in females than in males, respectively [see Use in Specific Populations ( 8.8) ].

    Renal Impairment: A study of subjects with varying degrees of renal impairment (creatinine clearance between 10 and 136 mL/min) given darifenacin hydrobromide extended-release tablets 15 mg (base) once daily to steady-state demonstrated no clear relationship between renal function and darifenacin clearance [see Use in Specific Populations ( 8.7) ].

    Hepatic Impairment: Darifenacin hydrobromide extended-release tablets pharmacokinetics were investigated in subjects with mild (Child-Pugh A) or moderate (Child-Pugh B) impairment of hepatic function given darifenacin hydrobromide extended-release tablets 15 mg (base) once daily to steady-state. Mild hepatic impairment had no effect on the pharmacokinetics of darifenacin. However, protein binding of darifenacin was affected by moderate hepatic impairment. After adjusting for plasma protein binding, unbound darifenacin exposure was estimated to be 4.7-fold higher in subjects with moderate hepatic impairment than subjects with normal hepatic function. Subjects with severe hepatic impairment (Child-Pugh C) have not been studied [see DOSAGE AND ADMINISTRATION ( 2) ,Warning and Precautions ( 5.6) and Use in Specific Population ( 8.6) ].

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity studies with darifenacin were conducted in mice and rats. No evidence of drug-related carcinogenicity was revealed in a 24-month study in mice at dietary doses up to 100 mg/kg/day or approximately 32 times the estimated free plasma AUC reached at the maximum recommended human dose (the AUC at the MRHD) of 15 mg and in a 24-month study in rats at doses up to 15 mg/kg/day or up to approximately 12 times the AUC at the MRHD in female rats and approximately eight times the AUC at the MRHD in male rats.

    Darifenacin was not genotoxic in the bacterial mutation assay (Ames test), the Chinese hamster ovary assay, the human lymphocyte assay, or the in vivo mouse bone marrow cytogenetics assay.

    There was no evidence for effects on fertility in male or female rats treated at oral doses up to approximately 78 times (50 mg/kg/day) the AUC at the MRHD.

  • 14 CLINICAL STUDIES

    Darifenacin hydrobromide extended-release tablets were evaluated for the treatment of patients with overactive bladder with symptoms of urgency, urge urinary incontinence, and increased urinary frequency in three randomized, fixed-dose, placebo-controlled, multicenter, double-blind, 12-week studies (Studies 1, 2 and 3) and one randomized, double-blind, placebo-controlled, multicenter, dose-titration study (Study 4). For study eligibility in all four studies, patients with symptoms of overactive bladder for at least six months were required to demonstrate at least eight micturitions and at least one episode of urinary urgency per day, and at least five episodes of urge urinary incontinence per week. The majority of patients were white (94 percent) and female (84 percent), with a mean age of 58 years, range 19 to 93 years. Thirty-three percent of patients were ≥65 years of age. These characteristics were well balanced across treatment groups. The study population was inclusive of both naïve patients who had not received prior pharmacotherapy for overactive bladder (60 percent) and those who had (40 percent).

    Table 4 shows the efficacy data collected from 7- or 14-day voiding diaries in the three fixed-dose placebo-controlled studies of 1,059 patients treated with placebo, 7.5 mg or 15 mg (base) once daily darifenacin hydrobromide extended-release tablets for 12 weeks. A significant decrease in the primary endpoint, change from baseline in average weekly urge urinary incontinence episodes was observed in all three studies. Data is also shown for two secondary endpoints, change from baseline in the average number of micturitions per day (urinary frequency) and change from baseline in the average volume voided per micturition.

  • 17 PATIENT COUNSELING INFORMATION

    “See FDA-approved patient labeling (Patient Information)”

    Patients should be informed that anticholinergic agents, such as darifenacin hydrobromide extended-release tablets, may produce clinically significant adverse effects related to anticholinergic pharmacological activity including constipation, urinary retention and blurred vision. Heat prostration (due to decreased sweating) can occur when anticholinergics such as darifenacin hydrobromide extended-release tablets are used in a hot environment. Because anticholinergics, such as darifenacin hydrobromide extended-release tablets, may produce dizziness or blurred vision, patients should be advised to exercise caution in decisions to engage in potentially dangerous activities until the drug’s effects have been determined. Patients should read the patient information leaflet before starting therapy with darifenacin hydrobromide extended-release tablets.

    Patients should be informed that darifenacin may produce clinically significant angioedema that may result in airway obstruction. Patients should be advised to promptly discontinue darifenacin therapy and seek immediate medical attention if they experience edema of the tongue or laryngopharynx, or difficulty breathing.

    Darifenacin hydrobromide extended-release tablets should be taken once daily with water. They may be taken with or without food, and should be swallowed whole and not chewed, divided or crushed.
