`
`compatible diluent and should be administered intravenously over
`a period of 30 minutes to 60 minutes. (2.1)
`
`
`
`
` Oral-Intravenous Replacement therapy (2.1): When switching
`
`from oral VIMPAT, the initial total daily intravenous dosage of
`VIMPAT should be equivalent to the total daily dosage and
`frequency of oral VIMPAT. At the end of the intravenous
`treatment period, the patient may be switched to VIMPAT oral
`administration at the equivalent daily dosage and frequency of the
`intravenous administration.

`
`providers should recommend a device that can measure and deliver the prescribed dose accurately,
`and provide instructions for measuring the dosage.
`
`
`
` 2.1 Partial-Onset Seizures
`
`VIMPAT can be initiated with either oral or intravenous administration. The initial dose should be 50
`mg twice daily (100 mg per day). Based on individual patient response and tolerability, the dose can
`be increased at weekly intervals by 100 mg per day given as two divided doses . The recommended
`maintenance dose is 200 mg to 400 mg/day, given as two divided doses. In clinical trials, the 600 mg
`daily dose was not more effective than the 400 mg daily dose, and was associated with a
`substantially higher rate of adverse reactions. [See Clinical Studies (14.1)]
`
`A gradual withdrawal of VIMPAT over at least 1 week is recommended. [See Withdrawal of
`
`Antiepileptic Drugs(5.5)]
`
`
`
`Switching from Oral to Intravenous Dosing
`
`When switching from oral VIMPAT, the initial total daily intravenous dosage of VIMPAT should be
`equivalent to the total daily dosage and frequency of oral VIMPAT and should be infused
`intravenously over a period of 30 minutes to 60 minutes. There is experience with twice daily
`intravenous infusion for up to 5 days.
`
`Switching from Intravenous to Oral Dosing
`
`
`At the end of the intravenous treatment period, the patient may be switched to VIMPAT oral
`
`
`administration at the equivalent daily dosage and frequency of the intravenous administration.
`
`
`
`Compatibility and Stability
`
`
`VIMPAT injection can be administered intravenously without further dilution or may be mixed with
`diluents. VIMPAT injection was found to be physically compatible and chemically stable when mixed
`with the following diluents for at least 24 hours and stored in glass or polyvinyl chloride (PVC) bags at
`ambient room temperature 15°C to 30°C (59°F to 86°F).

`
`The stability of VIMPAT injection in other infusion solutions has not been evaluated. Product with
`particulate matter or discoloration should not be used.
`
`Any unused portion of VIMPAT injection should be discarded.
`
`2.2 Patients with Renal Impairment
`
`No dose adjustment is necessary in patients with mild to moderate renal impairment. A maximum
`dose of 300 mg per day VIMPAT is recommended for patients with severe renal impairment
`[creatinine clearance (CLCR) less than or equal to 30 mL/min] and in patients with endstage renal
`
`disease. VIMPAT is effectively removed from plasma by hemodialysis. Following a 4-hour
`hemodialysis treatment, dosage supplementation of up to 50% should be considered. In all renally
`
`impaired patients, the dose titration should be performed with caution. Patients with renal impairment
`who are taking strong inhibitors of CYP3A4 and CYP2C9 may have a significant increase in exposure
`to VIMPAT. Dose reduction may be necessary in these patients. [See Use in Specific Populations
`
`(8.6) and Clinical Pharmacology (12.3)]
`
`
`
` 2.3 Patients with Hepatic Impairment
`
`The dose titration should be performed with caution in patients with hepatic impairment. A maximum
`dose of 300 mg per day is recommended for patients with mild or moderate hepatic impairment.
`
`VIMPAT use is not recommended in patients with severe hepatic impairment. Patients with hepatic
`impairment who are taking strong inhibitors of CYP3A4 and CYP2C9 may have a significant increase
`in exposure to VIMPAT. Dose reduction may be necessary in these patients. [See Use in Specific
`Populations (8.7)and Clinical Pharmacology (12.3)]

`
`
`
` 5 WARNINGS AND PRECAUTIONS
`
`5.1 Suicidal Behavior and Ideation
`
`
`
`Antiepileptic drugs (AEDs), including VIMPAT, increase the risk of suicidal thoughts or behavior in
`patients taking these drugs for any indication. Patients treated with any AED for any indication should
`be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or
`any unusual changes in mood or behavior.
`
`Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11
`different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk
`
`
` (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients
`randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the
`estimated incidence of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%,
`compared to 0.24% among 16,029 placebo-treated patients, representing an increase of
`approximately one case of suicidal thinking or behavior for every 530 patients treated. There were
`four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the
`number of events is too small to allow any conclusion about drug effect on suicide.
`
`The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week
`after starting treatment with AEDs and persisted for the duration of treatment assessed. Because
`
`most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or
`behavior beyond 24 weeks could not be assessed.
`
`The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed.
`
`The finding of increased risk with AEDs of varying mechanisms of action and across a range of
`indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary
`substantially by age (5-100 years) in the clinical trials analyzed.
`
`Table 1 shows absolute and relative risk by indication for all evaluated AEDs.

`
`
`
`The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in
`clinical trials for psychiatric or other conditions, but the absolute risk differences were similar.
`
`Anyone considering prescribing VIMPAT or any other AED must balance this risk with the risk of
`untreated illness. Epilepsy and many other illnesses for which antiepileptics are prescribed are
`themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and
`behavior. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to
`consider whether the emergence of these symptoms in any given patient may be related to the illness
`being treated.
`
`Patients, their caregivers, and families should be informed that AEDs increase the risk of suicidal
`thoughts and behavior and should be advised of the need to be alert for the emergence or worsening
`of the signs and symptoms of depression, any unusual changes in mood or behavior, or the
`
`emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should
`be reported immediately to healthcare providers.
`
`
`5.2 Dizziness and Ataxia
`
`
`
`Patients should be advised that VIMPAT may cause dizziness and ataxia. Accordingly, they should
`be advised not to drive a car or to operate other complex machinery until they are familiar with the
`effects of VIMPAT on their ability to perform such activities.
`
`In patients with partial-onset seizures taking 1 to 3 concomitant AEDs, dizziness was experienced by
`25% of patients randomized to the recommended doses (200 to 400 mg/day) of VIMPAT (compared
`with 8% of placebo patients) and was the adverse event most frequently leading to discontinuation
`(3%). Ataxia was experienced by 6% of patients randomized to the recommended doses (200 to 400

`
`mg/day) of VIMPAT (compared to 2% of placebo patients). The onset of dizziness and ataxia was
`most commonly observed during titration. There was a substantial increase in these adverse events
`at doses higher than 400 mg/day. [See Adverse Reactions/Table 2 (6.1)]
`
`
`
` 5.3 Cardiac Rhythm and Conduction Abnormalities
`
`PR interval prolongation
`Dose-dependent prolongations in PR interval with VIMPAT have been observed in clinical studies in
`patients and in healthy volunteers. [See Clinical Pharmacology (12.2)] In clinical trials in patients with
`partial-onset epilepsy, asymptomatic first-degree atrioventricular (AV) block was observed as an
`adverse reaction in 0.4% (4/944) of patients randomized to receive VIMPAT and 0% (0/364) of
`patients randomized to receive placebo. In clinical trials in patients with diabetic neuropathy,
`asymptomatic first-degree AV block was observed as an adverse reaction in 0.5% (5/1023) of
`patients receiving VIMPAT and 0% (0/291) of patients receiving placebo. Second degree and
`complete AV block have been reported inpatients in pain studies and in patients with seizures. When
`VIMPAT is given with other drugs that prolong the PR interval, further PR prolongation is possible.
`
`VIMPAT should be used with caution in patients with known conduction problems (e.g. marked first-
`degree AV block, second-degree or higher AV block and sick sinus syndrome without pacemaker,
`sodium channelopathies (e.g., Brugada Syndrome), on concomitant medications that prolong PR
`interval, or with severe cardiac disease such as myocardial ischemia or heart failure, or structural
`heart disease. In such patients, obtaining an ECG before beginning VIMPAT, and after VIMPAT is
`titrated to steady-state, is recommended.
`
`
`Atrial fibrillation and Atrial flutter
`In the short-term investigational trials of VIMPAT in epilepsy patients, there were no cases of atrial
`fibrillation or flutter. Both atrial fibrillation and atrial flutter have been reported in open label epilepsy
`trials and in postmarketing experience. In patients with diabetic neuropathy, 0.5% of patients treated
`with VIMPAT experienced an adverse reaction of atrial fibrillation or atrial flutter, compared to 0% of
`placebo-treated patients. VIMPAT administration may predispose to atrial arrhythmias (atrial
`fibrillation or flutter), especially in patients with diabetic neuropathy and/or cardiovascular disease.
`
`5.4 Syncope

`
`FDA Approved Labeling Text dated 01/16/2014
`
`
`Page 8
`
` In the short-term controlled trials of VIMPAT in epilepsy patients with no significant system illnesses,
`
`there was no increase in syncope compared to placebo. In the short-term controlled trials of VIMPAT
`in patients with diabetic neuropathy, 1.2% of patients who were treated with VIMPAT reported an
`adverse reaction of syncope or loss of consciousness, compared to 0% of placebo-treated patients
`with diabetic neuropathy. Most of the cases of syncope were observed in patients receiving doses
`
`above 400 mg/day. The cause of syncope was not determined in most cases. However, several were
`associated with either changes in orthostatic blood pressure, atrial flutter/fibrillation (and associated
`
`tachycardia), or bradycardia.
`
`
`5.5 Withdrawal of Antiepileptic Drugs (AEDs)
`
`As with all AEDs, VIMPAT should be withdrawn gradually (over a minimum of 1 week) to minimize the
`potential of increased seizure frequency in patients with seizure disorders.
`
`
`
`
`5.6 Multiorgan Hypersensitivity Reactions
`One case of symptomatic hepatitis and nephritis was observed among 4011 subjects exposed to
`VIMPAT during clinical development. The event occurred in a healthy volunteer, 10 days after
`stopping VIMPAT treatment. The subject was not taking any concomitant medication and potential
`known viral etiologies for hepatitis were ruled out. The subject fully recovered within a month, without
`specific treatment. The case is consistent with a delayed multiorgan hypersensitivity reaction.
`Additional potential cases included 2 with rash and elevated liver enzymes and 1 with myocarditis and
`hepatitis of uncertain etiology.
`
`Multiorgan hypersensitivity reactions (also known as Drug Reaction with Eosinophilia and Systemic
`Symptoms, or DRESS) have been reported with other anticonvulsants and typically, although not
`exclusively, present with fever and rash associated with other organ system involvement, that may or
`may not include eosinophilia, hepatitis, nephritis, lymphadenopathy, and/or myocarditis. Because this
`disorder is variable in its expression, other organ system signs and symptoms not noted here may
`occur. If this reaction is suspected, VIMPAT should be discontinued and alternative treatment
`started.

`VIMPAT oral solution contains aspartame, a source of phenylalanine. A 200 mg dose of VIMPAT oral
`solution (equivalent to 20 mL) contains 0.32 mg of phenylalanine.
`
`6 ADVERSE REACTIONS
`
`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.
`
`In all controlled and uncontrolled trials in patients with partial-onset seizures, 1327 patients have
`received VIMPAT of whom 1000 have been treated for longer than 6 months and 852 for longer than
`12 months.
`
`6.1 Clinical Trials Experience
`
`Controlled Trials
`
`
`
`
`
` Adverse reactions leading to discontinuation
`
`In controlled clinical trials, the rate of discontinuation as a result of an adverse event was 8% and
`17% in patients randomized to receive VIMPAT at the recommended doses of 200 and 400 mg/day,
`respectively, 29% at 600 mg/day, and 5% in patients randomized to receive placebo. The adverse
`events most commonly (>1% in the VIMPAT total group and greater than placebo) leading to
`discontinuation were dizziness, ataxia, vomiting, diplopia, nausea, vertigo, and vision blurred.
`
`Most common adverse reactions
`
`
`Table 2 gives the incidence of treatment-emergent adverse events that occurred in ≥2% of adult
`patients with partial-onset seizures in the total VIMPAT group and for which the incidence was greater
`than placebo. The majority of adverse events in the VIMPAT patients were reported with a maximum
`intensity of 'mild' or 'moderate'.

`
` Laboratory abnormalities
`
`Abnormalities in liver function tests have been observed in controlled trials with VIMPAT in adult
`patients with partial-onset seizures who were taking 1 to 3 concomitant anti-epileptic drugs.
`Elevations of ALT to ≥3× ULN occurred in 0.7% (7/935) of VIMPAT patients and 0% (0/356) of
`placebo patients. One case of hepatitis with transaminases >20x ULN was observed in one healthy
`subject 10 days after VIMPAT treatment completion, along with nephritis (proteinuria and urine casts).

`
`Serologic studies were negative for viral hepatitis. Transaminases returned to normal within one
`month without specific treatment. At the time of this event, bilirubin was normal. The
`hepatitis/nephritis was interpreted as a delayed hypersensitivity reaction to VIMPAT.
`
`
`
` Other Adverse Reactions in Patients with Partial-Onset Seizures
`
`The following is a list of treatment-emergent adverse events reported by patients treated with
`VIMPAT in all clinical trials in patients with partial-onset seizures, including controlled trials and long-
`term open-label extension trials. Events addressed in other tables or sections are not listed here.
`Events included in this list from the controlled trials occurred more frequently on drug than on placebo
`and were based on consideration of VIMPAT pharmacology, frequency above that expected in the
`population, seriousness, and likelihood of a relationship to VIMPAT. Events are further classified
`within system organ class.
`
`Blood and lymphatic system disorders: neutropenia, anemia
`
`Cardiac disorders: palpitations
`
`Ear and labyrinth disorders: tinnitus
`
`
`Gastrointestinal disorders: constipation, dyspepsia, dry mouth, oral hypoaesthesia
`
`General disorders and administration site conditions: irritability, pyrexia, feeling drunk
`
`
`Injury, poisoning, and procedural complications: fall
`
`Musculoskeletal and connective tissue disorders: muscle spasms
`
`
`
`Nervous system disorders: paresthesia, cognitive disorder, hypoaesthesia, dysarthria, disturbance in
`attention, cerebellar syndrome
`
`Psychiatric disorders: confusional state, mood altered, depressed mood
`
`
`
` Intravenous Adverse Reactions
`
`Adverse reactions with intravenous administration generally appeared similar to those observed with
`the oral formulation, although intravenous administration was associated with local adverse events
`such as injection site pain or discomfort (2.5%), irritation (1%), and erythema (0.5%). One case of
`profound bradycardia (26 bpm: BP 100/60 mmHg) was observed in a patient during a 15 minute
`infusion of 150 mg VIMPAT. This patient was on a beta-blocker. Infusion was discontinued and the
`patient experienced a rapid recovery.

`
` Comparison of Gender and Race
`
`
`
`The overall adverse event rate was similar in male and female patients. Although there were few non-
`
` Caucasian patients, no differences in the incidences of adverse events compared to Caucasian
`patients were observed.
`
`6.2 Postmarketing Experience
`
`
`The following adverse reactions have been identified during post-approval use of VIMPAT. 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.
`Blood and lymphatic system disorders: Agranulocytosis
`
`Cardiac disorders: Bradycardia
`Psychiatric disorders: Aggression, agitation, hallucination, insomnia, psychotic disorder
`
`Skin and subcutaneous tissue disorders: Angioedema, rash, urticaria, Stevens-Johnson syndrome,
`
`toxic epidermal necrolysis
`7 DRUG INTERACTIONS
`
`Drug-drug interaction studies in healthy subjects showed no pharmacokinetic interactions between
`VIMPAT and carbamazepine, valproate, digoxin, metformin, omeprazole, midazolam, or an oral
`contraceptive containing ethinylestradiol and levonorgestrel. There was no evidence for any relevant
`drug-drug interaction of VIMPAT with common AEDs in the placebo-controlled clinical trials in
`patients with partial-onset seizures. [See Clinical Pharmacology (12.3)]
`
`The lack of pharmacokinetic interaction does not rule out the possibility of pharmacodynamic
`
`interactions, particularly among drugs that affect the heart conduction system.
`
`
`Patients with renal or hepatic impairment who are taking strong inhibitors of CYP3A4 and CYP2C9
`may have a significant increase in exposure to VIMPAT. Dose reduction may be necessary in these
`patients.

`
`Lacosamide produced developmental toxicity (increased embryofetal and perinatal mortality, growth
`deficit) in rats following administration during pregnancy. Developmental neurotoxicity was observed
`in rats following administration during a period of postnatal development corresponding to the third
`trimester of human pregnancy. These effects were observed at doses associated with clinically
`relevant plasma exposures.
`Lacosamide has been shown in vitro to interfere with the activity of collapsin response mediator
`protein-2 (CRMP-2), a protein involved in neuronal differentiation and control of axonal outgrowth.
`Potential related adverse effects on CNS development cannot be ruled out.
`
`
`There are no adequate and well-controlled studies in pregnant women. VIMPAT should be used
`during pregnancy only if the potential benefit justifies the potential risk to the fetus.
`
`Oral administration of lacosamide to pregnant rats (20, 75, or 200 mg/kg/day) and rabbits (6.25, 12.5,
`or 25 mg/kg/day) during the period of organogenesis did not produce any teratogenic effects.
`
` However, the maximum doses evaluated were limited by maternal toxicity in both species and
`embryofetal death in rats. These doses were associated with maternal plasma lacosamide
`exposures [area under the plasma-time concentration curve; (AUC)] ≈2 and 1 times (rat and rabbit,
`respectively) that in humans at the maximum recommended human dose (MRHD) of 400 mg/day.
`
`When lacosamide (25, 70, or 200 mg/kg/day) was orally administered to rats throughout gestation,
`parturition, and lactation, increased perinatal mortality and decreased body weights were observed in
`the offspring at the highest dose. The no-effect dose for pre- and post-natal developmental toxicity in
`rats (70 mg/kg/day) was associated with a maternal plasma lacosamide AUC approximately equal to
`that in humans at the MRHD.
`
`Oral administration of lacosamide (30, 90, or 180 mg/kg/day) to rats during the neonatal and juvenile
`periods of postnatal development resulted in decreased brain weights and long-term neurobehavioral
`changes (altered open field performance, deficits in learning and memory). The early postnatal
`period in rats is generally thought to correspond to late pregnancy in humans in terms of brain
`development. The no-effect dose for developmental neurotoxicity in rats was associated with a
`plasma lacosamide AUC approximately 0.5 times that in humans at the MRHD.

`access and reach, either a healthcare provider or the patient can initiate enrollment in the UCB AED
`Pregnancy Registry by calling 1-888-537-7734 (toll free).
`
`Physicians are also advised to recommend that pregnant patients taking VIMPAT enroll in the North
`American Antiepileptic Drug Pregnancy Registry. This can be done by calling the toll free number 1-
`888-233-2334, and must be done by patients themselves. Information on the registry can also be
