The pediatric indication for VIMPAT is based on the principle of extrapolation of efficacy data from adults and is supported by safety and pharmacokinetics data collected in children.

The efficacy of VIMPAT in pediatric patients 4 years of age and older with partial-onset seizures was confirmed in a placebo-controlled pediatric trial.

Adult Efficacy Data

Pediatric Placebo-Controlled Trial

The pediatric indication for VIMPAT is based on the principle of extrapolation of efficacy data from adults and is supported by safety and pharmacokinetics data collected in children.

The efficacy of VIMPAT in pediatric patients 4 years of age and older with partial-onset seizures was confirmed in a placebo-controlled pediatric trial.


INDICATION

VIMPAT® is indicated for the treatment of partial-onset seizures in patients 4 years of age and older.

As the safety of VIMPAT injection in pediatric patients has not been established, VIMPAT injection is indicated for the treatment of partial-onset seizures only in adult patients (17 years of age and older).

SELECT IMPORTANT SAFETY INFORMATION

VIMPAT is associated with important warnings and precautions including suicidal behavior and ideation, dizziness and ataxia, cardiac rhythm and conduction abnormalities, syncope, and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multi-organ hypersensitivity.

In the adult monotherapy clinical trial, adverse reactions were generally similar to those observed and attributed to drug in adjunctive placebo-controlled trials, with the exception of insomnia (observed at a higher rate of ≥2%). In the adult adjunctive placebo-controlled trials, the most common adverse reactions (≥10% and greater than placebo) were dizziness, headache, nausea, and diplopia. Pediatric adverse reactions were similar to those seen in adult patients.

VIMPAT is a Schedule V controlled substance.

Important Safety Information

Warnings and Precautions

  • Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including VIMPAT, increase the risk of suicidal behavior and ideation. Monitor patients taking VIMPAT for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Advise patients and caregivers to be alert for these behavioral changes and to immediately report them to the healthcare provider.

  • Dizziness and Ataxia: VIMPAT may cause dizziness and ataxia. In adult clinical trials, the onset of dizziness and ataxia was most commonly observed during titration. Advise patients not to drive, operate complex machinery, or engage in other hazardous activities until they are familiar with the effects of VIMPAT on their ability to perform such activities. Dizziness and ataxia were also observed in pediatric clinical trials.

  • Cardiac Rhythm and Conduction Abnormalities

    PR Interval Prolongation, Atrioventricular Block, and Ventricular Tachyarrhythmia
    Dose-dependent prolongations in PR interval with VIMPAT have been observed in clinical studies in adult patients and in healthy volunteers. When VIMPAT is given with other drugs that prolong the PR interval, further PR prolongation is possible.

    In the postmarketing setting, there have been reports of cardiac arrhythmias in patients treated with VIMPAT, including bradycardia, AV block, and ventricular tachyarrhythmia, which have rarely resulted in asystole, cardiac arrest, and death. Most, although not all, cases have occurred in patients with underlying proarrhythmic conditions, or in those taking concomitant medications that affect cardiac conduction or prolong the PR interval. These events have occurred with both oral and intravenous routes of administration and at prescribed doses as well as in the setting of overdose.

    VIMPAT should be used with caution in patients with underlying proarrhythmic conditions such as known cardiac conduction problems (e.g., marked first-degree AV block, second-degree or higher AV block, and sick sinus syndrome without pacemaker), severe cardiac disease (such as myocardial ischemia or heart failure, or structural heart disease), and cardiac sodium channelopathies (e.g., Brugada Syndrome).

    VIMPAT should also be used with caution in patients on concomitant medications that affect cardiac conduction, including sodium channel blockers, beta-blockers, calcium channel blockers, potassium channel blockers, and medications that prolong the PR interval. In such patients, obtaining an ECG before beginning VIMPAT, and after VIMPAT is titrated to steady-state maintenance dose, is recommended. In addition, these patients should be closely monitored if they are administered VIMPAT through the intravenous route. Patients should be made aware of and report cardiac signs or symptoms to their healthcare provider right away.

    Atrial Fibrillation and Atrial Flutter
    VIMPAT administration may predispose to atrial arrhythmias (atrial fibrillation or flutter), especially in patients with diabetic neuropathy and/or cardiovascular disease.

  • Syncope: VIMPAT may cause syncope in adult and pediatric patients.

  • Withdrawal of Antiepileptic Drugs: Gradually withdraw VIMPAT (over a minimum of 1 week) to minimize the potential of increased seizure frequency.

  • Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Also known as multi-organ hypersensitivity, has been reported with antiepileptic drugs, including VIMPAT. Some of these events have been fatal or life-threatening. If signs or symptoms are present, immediately evaluate the patient. Discontinue VIMPAT if an alternative etiology for the signs and symptoms cannot be established.

  • Risks in Patients with Phenylketonuria: VIMPAT oral solution contains aspartame, a source of phenylalanine, which can be harmful in patients with phenylketonuria (PKU). A 200 mg dose of VIMPAT oral solution (equivalent to 20 mL) contains 0.32 mg of phenylalanine.

Adverse Reactions

  • Adjunctive therapy: In the adult placebo-controlled clinical trials, the most frequently seen adverse reaction with VIMPAT was dizziness (31% vs 8% placebo). Other common adverse reactions occurring in ≥10 percent of VIMPAT-treated patients, and greater than placebo, were headache, nausea, and diplopia.

  • Monotherapy: In the adult clinical trial, adverse reactions were generally similar to those observed and attributed to drug in adjunctive placebo-controlled trials, with the exception of insomnia (occurred at a higher rate of ≥2%).

  • Pediatric patients: Adverse reactions reported in clinical studies of pediatric patients 4 to less than 17 years of age were similar to those seen in adult patients.

  • Injection: In adult adjunctive therapy clinical trials, adverse reactions with intravenous administration generally were similar to those that occurred with the oral formulation, although intravenous administration was associated with local adverse reactions such as injection site pain or discomfort (2.5%), irritation (1%), and erythema (0.5%). When administering a loading dose, the incidence of CNS adverse reactions, such as dizziness, somnolence, and paresthesia, may be higher with 15-minute administration than over a 30- to 60-minute period.

Dosing Considerations

VIMPAT injection is for intravenous and adult use only when oral administration is temporarily not feasible. The loading dose for adult patients should be administered with medical supervision considering the VIMPAT pharmacokinetics and increased incidence of CNS adverse reactions. The safety of VIMPAT injection and the use of a loading dose in pediatric patients have not been studied. Dosage adjustments are recommended for patients with mild or moderate hepatic impairment or severe renal impairment. Use in patients with severe hepatic impairment is not recommended. Perform dose titration with caution in all patients with renal and/or hepatic impairment.

VIMPAT is a Schedule V controlled substance.
