Adverse Reactions
6 ADVERSE REACTIONS The following serious adverse reactions are described in more detail in the Warnings and Precautions section of the labeling: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity [see Warnings and Precautions ( 5.1 )] QT Shortening [see Warnings and Precautions ( 5.2 )] Suicidal Behavior and Ideation [see Warnings and Precautions ( 5.3 )] Neurological Adverse Reactions [see Warnings and Precautions ( 5.4 )] Withdrawal of Antiepileptic Drugs [see Warnings and Precautions ( 5.5 )] The most common adverse reactions in patients receiving XCOPRI (at least 10% for XCOPRI and more frequently than placebo) include somnolence, dizziness, fatigue, diplopia, and headache. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact SK Life Science, Inc. at 1-866-657-5574 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions and for varying durations, adverse reaction frequencies observed in the clinical trials of a drug cannot be directly compared with frequencies in the clinical trials of another drug and may not reflect the frequencies observed in practice. In all controlled and uncontrolled trials performed in adult partial-onset seizure patients, XCOPRI was administered as adjunctive therapy to 1944 patients. Of these patients, 1575 were treated for at least 6 months, 710 for at least 12 months, 349 for at least 24 months, and 320 for at least 36 months. A total of 658 patients (442 patients treated with XCOPRI and 216 patients treated with placebo) constituted the safety population in the pooled analysis of placebo-controlled studies in patients with partial-onset seizures (Studies 1 and 2) [see Clinical Studies ( 14 )] . The adverse reactions presented in Table 4 are based on this safety population; the median length of treatment in these studies was 18 weeks. Of the patients in those studies, approximately 49% were male, 76% were Caucasian, and the mean age was 39 years. In Study 1 and Study 2, adverse events occurred in 77% of patients treated with XCOPRI and 68% treated with placebo. Table 4 gives the incidence of adverse reactions that occurred in subjects with partial-onset seizures in any XCOPRI treatment group and for which the incidence was greater than placebo during the controlled clinical trials. The most common adverse reactions that occurred in XCOPRI-treated patients (incidence at least 10% and greater than placebo) were somnolence, dizziness, fatigue, diplopia, and headache. The discontinuation rates because of adverse events were 11%, 9%, and 21% for patients randomized to receive XCOPRI at doses of 100 mg/day, 200 mg/day, and 400 mg/day, respectively, compared to 4% in patients randomized to receive placebo. The adverse reactions most commonly (1% or greater in any XCOPRI treatment group, and greater than placebo) leading to discontinuation, in descending order of frequency, were ataxia, dizziness, somnolence, diplopia, nystagmus, and vertigo.

The maximum ALT elevation was 7.6 times ULN in patients treated with 400 mg XCOPRI. Potassium In clinical studies, there was a post-baseline elevation of potassium values greater than 5 meq/L (upper reference range) in patients treated with XCOPRI. In Study 1, there were 17 (17%) patients treated with XCOPRI 200 mg compared to 8 (7%) patients who took placebo with normal baseline potassium values who had at least one post-baseline maximum value greater than 5 meq/L. In Study 2, there was a dose-related distribution where at least one post-baseline potassium value was greater than 5 meq/L, occurring in 8.3%, 9.1%, and 10.8% of the patients treated with XCOPRI 100 mg, 200 mg, and 400 mg, respectively, compared to 5.6% of patients who took placebo. Two patients had a maximum potassium value of 5.9 meq/L. Other Adverse Reactions Gastrointestinal disorders: There was an incidence of appendicitis in the overall clinical trial safety population of 2.9 cases of appendicitis/1000 patient-years of exposure that is in excess of the expected background rate in the general population. Adverse Reactions Based on Gender No significant gender differences were noted in the incidence of adverse reactions. 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of XCOPRI. 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. Psychiatric Disorders: psychosis (hallucinations, delusions/paranoia), hostility, aggression.

Indications And Usage
1 INDICATIONS AND USAGE XCOPRI is indicated for the treatment of partial-onset seizures in adult patients. XCOPRI is indicated for the treatment of partial-onset seizures in adult patients. ( 1 )
Abuse
9.2 Abuse Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. In a human abuse potential study conducted in recreational sedative abusers (n=39), single doses of XCOPRI (200 mg and 400 mg) were compared to placebo. XCOPRI at single doses of 400 mg produced responses on positive subjective measures such as “Drug Liking,” “Overall Drug Liking,” “Take Drug Again,” and “Good Drug Effects” that were statistically greater than the responses produced on these measures by placebo. In this study, euphoric mood occurred at greater extent with XCOPRI (400 mg) (8%) than with placebo (0%). Phase 1 multiple ascending dose studies in healthy subjects showed rates of euphoria and feeling drunk of about 3% and disturbance in attention of about 5% in subjects who received supratherapeutic doses of cenobamate, but these adverse events were absent in the placebo group. In Phase 2 and 3 studies in subjects with epilepsy, euphoric mood, confusional state, and sedation occurred at low rates in subjects who received XCOPRI (0.5-2.5%).
Controlled Substance
9.1 Controlled Substance XCOPRI contains cenobamate and is listed as a Schedule V controlled substance.
Dependence
9.3 Dependence Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. Clinical studies in healthy subjects indicate that XCOPRI may cause physical dependence and lead to a withdrawal syndrome characterized by insomnia, decreased appetite, depressed mood, tremor, and amnesia. XCOPRI should be withdrawn gradually [see Warnings and Precautions ( 5.5 )] .

Clinical Pharmacology
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action The precise mechanism by which cenobamate exerts its therapeutic effects in patients with partial-onset seizures is unknown. Cenobamate has been demonstrated to reduce repetitive neuronal firing by inhibiting voltage-gated sodium currents. It is also a positive allosteric modulator of the γ-aminobutyric acid (GABA A ) ion channel. 12.2 Pharmacodynamics Interactions with Alcohol No clinically significant differences on objective attention, psychomotor performance, and memory tests, in addition to other subjective CNS tests, were observed following concomitant use of XCOPRI and ethanol (preparation of 40% ethanol in orange juice dosed at 0.7 g/kg for males and 0.57 g/kg for females) in healthy subjects. Cardiac Electrophysiology In a placebo-controlled QT study in healthy volunteers, dose-dependent shortening of the QTcF interval has been observed with XCOPRI [see Warnings and Precautions ( 5.2 )] . The mean ΔΔQTc is -11 [-13, -8] msec for 200 mg once daily and -18 [-22, -15] msec for 500 mg once daily (1.25 times the maximum recommended dosage). A higher percentage of XCOPRI-treated subjects (31% at 200 mg and 66% at 500 mg) had a QT shortening of greater than 20 msec compared to placebo (6-17%). Reductions of the QTc interval below 300 msec were not observed. 12.3 Pharmacokinetics Cenobamate AUC increases in a greater than dose-proportional manner following single oral doses from 5 to 750 mg (0.0125 to 1.88 times the maximum recommended dosage). Cenobamate C max increases in a dose proportional manner. Steady-state plasma concentrations are attained after approximately two weeks of once daily dosing. The pharmacokinetics of cenobamate are similar when used as monotherapy or as adjunctive therapy for the treatment of partial-onset seizures, except plasma cenobamate multiple-dose exposure (C max , AUC) decreased with co-administration of phenytoin by 27-28%. Absorption At least 88% of XCOPRI is absorbed following oral administration, with median T max ranging from 1 to 4 hours. Effect of Food No clinically significant differences in cenobamate pharmacokinetics were observed following administration of a high-fat meal (800-1000 calories with 50% fat). Distribution The apparent volume of distribution (Vd/F) of cenobamate after oral administration of XCOPRI is approximately 40-50 L. Plasma protein binding of cenobamate is 60% and independent of concentration in vitro . Cenobamate primarily binds with human albumin protein. Elimination The apparent terminal half-life of cenobamate is 50-60 hours and apparent oral clearance is approximately 0.45-0.63 L/hour over a dose range from 100 mg/day to 400 mg/day. Metabolism Cenobamate is extensively metabolized. The primary metabolic pathways are by glucuronidation via UGT2B7 and to a lesser extent by UGT2B4, and by oxidation via CYP2E1, CYP2A6, CYP2B6, and to a lesser extent by CYP2C19 and CYP3A4/5. Following administration of radiolabeled cenobamate, unchanged cenobamate accounted for greater than 98% of the total AUC of radioactivity in plasma. Unchanged cenobamate accounted for 6.8% of the dose which was mainly excreted in the urine (6.4%). Excretion Following administration of radiolabeled cenobamate, a mean of 93.0% of the total radioactive dose was recovered in urine (87.8%) and feces (5.2%). More than 50% of the radioactivity was excreted within 72 hours of dosing. Specific Populations No clinically significant differences in the pharmacokinetics of cenobamate were observed based on age based on data from subjects age 18 years to 77 years, sex, or race/ethnicity based on data from subjects categorized as Asian, Black, Caucasian, Hispanic, or Other. Patients with Renal Impairment Cenobamate plasma AUC was 1.4 fold to 1.5 fold higher in subjects with mild (CLcr 60 to less than 90 mL/min) and moderate (CLcr 30 to less than 60 mL/min) following a single oral 200 mg dose of XCOPRI compared to healthy controls. In subjects with severe (CLcr less than 30 mL/min) renal impairment, cenobamate plasma AUC did not change significantly compared to healthy controls following single oral 100 mg dose of XCOPRI [see Use in Specific Populations ( 8.6 )] . The effect of hemodialysis on cenobamate pharmacokinetics has not been studied. Patients with Hepatic Impairment Cenobamate plasma AUC was 2.1-fold and 2.3-fold higher in subjects with mild (5-6 points on Child-Pugh assessment) and moderate (7-9 points on Child-Pugh assessment) hepatic impairment, respectively, following a single oral 200 mg dose of XCOPRI compared to matched healthy controls [see Dosage and Administration ( 2.3 ) and Use in Specific Populations ( 8.7 )] .The effect of severe hepatic impairment on cenobamate pharmacokinetics has not been studied. Drug Interaction Studies Clinical Studies Alcohol No clinically significant pharmacokinetic differences were observed for either cenobamate or alcohol when administered concomitantly. AEDs Multiple doses of concomitant XCOPRI 200 mg once daily increased phenytoin mean C max and AUC by 70% and 84%, respectively, and phenobarbital mean C max and AUC by 34% and 37%, respectively [see Drug Interactions ( 7.1 )] . Multiple doses of concomitant XCOPRI 200 mg once daily decreased carbamazepine mean C max and AUC each by 23% [see Drug Interactions ( 7.1 ] . No clinically significant differences in the pharmacokinetics of the following drugs were observed when used concomitantly with cenobamate: valproic acid, levetiracetam or lacosamide. Based on population PK analyses, during treatment within the 100-400 mg/day XCOPRI dose range, lamotrigine concentrations are expected to decrease by 21-52% [see Drug Interactions ( 7.1 )] ; and levetiracetam concentrations are expected to decrease by 4-13%, which is not expected to be clinically significant. In subjects treated with XCOPRI in Study 1 and Study 2, there was no clear relationship between efficacy and concomitant oxcarbazepine use. As such, the efficacy data from Study 1 and Study 2 do not support the existence of a clinically relevant interaction perpetrated by XCOPRI against oxcarbazepine. CYP Substrates Multiple doses of concomitant XCOPRI 200 mg once daily decreased total bupropion (CYP2B6 substrate) mean C max and AUC by 23% and 39%, respectively, and decreased midazolam (CYP3A substrate) mean C max and AUC by 61% and 72%, respectively [see Drug Interactions ( 7.1 )] . Multiple doses of concomitant XCOPRI 200 mg once daily increased the omeprazole (CYP2C19 substrate) mean C max and AUC by 83% and 107%, respectively [see Drug Interactions ( 7.1 )] . No clinically significant differences in the pharmacokinetics of warfarin (CYP2C9 substrate) were observed when used concomitantly with cenobamate. The effects of concomitant AEDs on cenobamate PK Plasma cenobamate multiple-dose exposure (C max , AUC) decreased with co-administration of phenytoin by 27-28%. However, repeated dosing of valproate, phenobarbital, and carbamazepine did not have any significant impact on plasma cenobamate multiple-dose exposure. In Vitro Studies CYP Enzymes Cenobamate inhibits CYP2B6, CYP2C19, and CYP3A, but cenobamate does not inhibit CYP1A2, CYP2C8, CYP2C9, or CYP2D6. Cenobamate induces CYP2B6, CYP2C8, and CYP3A4, but cenobamate does not induce CYP1A2, CYP2C9, or CYP2C19. Transporters Systems Cenobamate was not a substrate of P-gp, BCRP, OAT1, OAT3, OCT2, MATE1, or MATE2-K, and cenobamate did not inhibit P-gp, OAT1, OCT1, OCT2, OATP1B3, BSEP, OAT3, or OATP1B1.

Cenobamate has been demonstrated to reduce repetitive neuronal firing by inhibiting voltage-gated sodium currents. It is also a positive allosteric modulator of the γ-aminobutyric acid (GABA A ) ion channel.
Pharmacodynamics
12.2 Pharmacodynamics Interactions with Alcohol No clinically significant differences on objective attention, psychomotor performance, and memory tests, in addition to other subjective CNS tests, were observed following concomitant use of XCOPRI and ethanol (preparation of 40% ethanol in orange juice dosed at 0.7 g/kg for males and 0.57 g/kg for females) in healthy subjects. Cardiac Electrophysiology In a placebo-controlled QT study in healthy volunteers, dose-dependent shortening of the QTcF interval has been observed with XCOPRI [see Warnings and Precautions ( 5.2 )] . The mean ΔΔQTc is -11 [-13, -8] msec for 200 mg once daily and -18 [-22, -15] msec for 500 mg once daily (1.25 times the maximum recommended dosage). A higher percentage of XCOPRI-treated subjects (31% at 200 mg and 66% at 500 mg) had a QT shortening of greater than 20 msec compared to placebo (6-17%). Reductions of the QTc interval below 300 msec were not observed.
Pharmacokinetics
12.3 Pharmacokinetics Cenobamate AUC increases in a greater than dose-proportional manner following single oral doses from 5 to 750 mg (0.0125 to 1.88 times the maximum recommended dosage). Cenobamate C max increases in a dose proportional manner. Steady-state plasma concentrations are attained after approximately two weeks of once daily dosing. The pharmacokinetics of cenobamate are similar when used as monotherapy or as adjunctive therapy for the treatment of partial-onset seizures, except plasma cenobamate multiple-dose exposure (C max , AUC) decreased with co-administration of phenytoin by 27-28%. Absorption At least 88% of XCOPRI is absorbed following oral administration, with median T max ranging from 1 to 4 hours. Effect of Food No clinically significant differences in cenobamate pharmacokinetics were observed following administration of a high-fat meal (800-1000 calories with 50% fat). Distribution The apparent volume of distribution (Vd/F) of cenobamate after oral administration of XCOPRI is approximately 40-50 L. Plasma protein binding of cenobamate is 60% and independent of concentration in vitro . Cenobamate primarily binds with human albumin protein. Elimination The apparent terminal half-life of cenobamate is 50-60 hours and apparent oral clearance is approximately 0.45-0.63 L/hour over a dose range from 100 mg/day to 400 mg/day. Metabolism Cenobamate is extensively metabolized. The primary metabolic pathways are by glucuronidation via UGT2B7 and to a lesser extent by UGT2B4, and by oxidation via CYP2E1, CYP2A6, CYP2B6, and to a lesser extent by CYP2C19 and CYP3A4/5. Following administration of radiolabeled cenobamate, unchanged cenobamate accounted for greater than 98% of the total AUC of radioactivity in plasma. Unchanged cenobamate accounted for 6.8% of the dose which was mainly excreted in the urine (6.4%). Excretion Following administration of radiolabeled cenobamate, a mean of 93.0% of the total radioactive dose was recovered in urine (87.8%) and feces (5.2%). More than 50% of the radioactivity was excreted within 72 hours of dosing. Specific Populations No clinically significant differences in the pharmacokinetics of cenobamate were observed based on age based on data from subjects age 18 years to 77 years, sex, or race/ethnicity based on data from subjects categorized as Asian, Black, Caucasian, Hispanic, or Other. Patients with Renal Impairment Cenobamate plasma AUC was 1.4 fold to 1.5 fold higher in subjects with mild (CLcr 60 to less than 90 mL/min) and moderate (CLcr 30 to less than 60 mL/min) following a single oral 200 mg dose of XCOPRI compared to healthy controls. In subjects with severe (CLcr less than 30 mL/min) renal impairment, cenobamate plasma AUC did not change significantly compared to healthy controls following single oral 100 mg dose of XCOPRI [see Use in Specific Populations ( 8.6 )] . The effect of hemodialysis on cenobamate pharmacokinetics has not been studied. Patients with Hepatic Impairment Cenobamate plasma AUC was 2.1-fold and 2.3-fold higher in subjects with mild (5-6 points on Child-Pugh assessment) and moderate (7-9 points on Child-Pugh assessment) hepatic impairment, respectively, following a single oral 200 mg dose of XCOPRI compared to matched healthy controls [see Dosage and Administration ( 2.3 ) and Use in Specific Populations ( 8.7 )] .The effect of severe hepatic impairment on cenobamate pharmacokinetics has not been studied. Drug Interaction Studies Clinical Studies Alcohol No clinically significant pharmacokinetic differences were observed for either cenobamate or alcohol when administered concomitantly. AEDs Multiple doses of concomitant XCOPRI 200 mg once daily increased phenytoin mean C max and AUC by 70% and 84%, respectively, and phenobarbital mean C max and AUC by 34% and 37%, respectively [see Drug Interactions ( 7.1 )] . Multiple doses of concomitant XCOPRI 200 mg once daily decreased carbamazepine mean C max and AUC each by 23% [see Drug Interactions ( 7.1 ] . No clinically significant differences in the pharmacokinetics of the following drugs were observed when used concomitantly with cenobamate: valproic acid, levetiracetam or lacosamide. Based on population PK analyses, during treatment within the 100-400 mg/day XCOPRI dose range, lamotrigine concentrations are expected to decrease by 21-52% [see Drug Interactions ( 7.1 )] ; and levetiracetam concentrations are expected to decrease by 4-13%, which is not expected to be clinically significant. In subjects treated with XCOPRI in Study 1 and Study 2, there was no clear relationship between efficacy and concomitant oxcarbazepine use. As such, the efficacy data from Study 1 and Study 2 do not support the existence of a clinically relevant interaction perpetrated by XCOPRI against oxcarbazepine. CYP Substrates Multiple doses of concomitant XCOPRI 200 mg once daily decreased total bupropion (CYP2B6 substrate) mean C max and AUC by 23% and 39%, respectively, and decreased midazolam (CYP3A substrate) mean C max and AUC by 61% and 72%, respectively [see Drug Interactions ( 7.1 )] . Multiple doses of concomitant XCOPRI 200 mg once daily increased the omeprazole (CYP2C19 substrate) mean C max and AUC by 83% and 107%, respectively [see Drug Interactions ( 7.1 )] . No clinically significant differences in the pharmacokinetics of warfarin (CYP2C9 substrate) were observed when used concomitantly with cenobamate. The effects of concomitant AEDs on cenobamate PK Plasma cenobamate multiple-dose exposure (C max , AUC) decreased with co-administration of phenytoin by 27-28%. However, repeated dosing of valproate, phenobarbital, and carbamazepine did not have any significant impact on plasma cenobamate multiple-dose exposure. In Vitro Studies CYP Enzymes Cenobamate inhibits CYP2B6, CYP2C19, and CYP3A, but cenobamate does not inhibit CYP1A2, CYP2C8, CYP2C9, or CYP2D6. Cenobamate induces CYP2B6, CYP2C8, and CYP3A4, but cenobamate does not induce CYP1A2, CYP2C9, or CYP2C19. Transporters Systems Cenobamate was not a substrate of P-gp, BCRP, OAT1, OAT3, OCT2, MATE1, or MATE2-K, and cenobamate did not inhibit P-gp, OAT1, OCT1, OCT2, OATP1B3, BSEP, OAT3, or OATP1B1.

Information For Patients
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Medication Guide ). DRESS/Multi-organ Hypersensitivity Instruct patients and caregivers that a fever or rash associated with signs of other organ system involvement (e.g., lymphadenopathy, hepatic dysfunction) may be drug-related and should be reported to their healthcare provider immediately. XCOPRI should be discontinued immediately if a serious hypersensitivity reaction is suspected [see Warnings and Precautions ( 5.1 )] . QT Shortening Instruct patients to inform their healthcare provider of all of the medications, over-the-counter medications, and herbal supplements that they are taking. Instruct patients to notify their healthcare provider if they have any symptoms of shortening of the QT interval, including prolonged heart palpitations or a loss of consciousness [see Warnings and Precautions ( 5.2 )] . Suicidal Behavior and Ideation Counsel patients, their caregivers, and/or families that antiepileptic drugs, including XCOPRI, may increase the risk of suicidal thoughts and behavior, and advise patients to be alert for the emergence or worsening of symptoms of depression; unusual changes in mood or behavior; or suicidal thoughts, behavior, or thoughts about self-harm. Advise patients, their caregivers, and/or families to report behaviors of concern immediately to a healthcare provider [see Warnings and Precautions ( 5.3 )] . Neurological Adverse Reactions Counsel patients that XCOPRI causes somnolence, fatigue, dizziness, and gait disturbance. These adverse reactions, if observed, are more likely to occur early in treatment but can occur at any time. Advise patients not to drive or operate machinery until they have gained sufficient experience on XCOPRI to gauge whether it adversely affects their ability to drive or operate machinery and that other CNS depressants or alcohol may have additive effects [see Warnings and Precautions ( 5.4 )] . Withdrawal of XCOPRI Advise patients not to discontinue use of XCOPRI without consulting with their healthcare provider. XCOPRI should normally be gradually withdrawn to reduce the potential for increased seizure frequency and status epilepticus [see Warnings and Precautions ( 5.5 )] . Contraceptives Counsel females of reproductive potential that XCOPRI may decrease the efficacy of oral contraceptives and advise them to use additional or alternative non-hormonal birth control [see Drug Interactions ( 7.1 )] . Pregnancy Advise patients to notify their healthcare provider if they become pregnant or intend to become pregnant during XCOPRI therapy. Encourage patients to enroll in the North American Antiepileptic Drug Pregnancy Registry if they become pregnant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy [see Use in Specific Populations ( 8.1 )] . Dosing Instructions Counsel patients that XCOPRI may be taken any time with or without food. Instruct patients that XCOPRI tablets should be swallowed whole with liquid and not chewed or crushed [see Dosage and Administration ( 2.1 )] . Abuse and Dependence Advise patients that XCOPRI is a federally controlled substance (CV) because it can be abused or lead to dependence [see Drug Abuse and Dependence ( 9 )] . Advise patients to keep their medication in a safe place to prevent misuse and abuse. Manufactured for: SK Life Science, Inc. Paramus, NJ 07652 Phone: 1-866-657-5574 © 2019 SK Life Science, Inc.

This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: 03/2020 MEDICATION GUIDE XCOPRI ® (ex-koh-pree) (cenobamate) tablets, for oral use, CV What is the most important information I should know about XCOPRI? XCOPRI can cause serious side effects, including: Serious or life threatening allergic reactions which may affect organs and other parts of your body like the liver or blood cells. You may or may not have a rash with these types of reactions. Call your healthcare provider right away and go to the nearest emergency room if you have any of the following: swelling of your face, eyes, lips, or tongue trouble swallowing or breathing a skin rash hives fever, swollen glands, or sore throat that does not go away or comes and goes painful sores in the mouth or around your eyes yellowing of your skin or eyes unusual bruising or bleeding severe fatigue or weakness severe muscle pain frequent infections that do not go away These symptoms may be the first signs of a serious reaction. A healthcare provider should examine you to decide if you should continue taking XCOPRI. Like other antiepileptic drugs, XCOPRI may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you: thoughts about suicide or dying attempts to commit suicide new or worse depression new or worse anxiety feeling agitated or restless panic attacks trouble sleeping (insomnia) new or worse irritability acting aggressive, being angry, or violent acting on dangerous impulses an extreme increase in activity and talking (mania) other unusual changes in behavior or mood Suicidal thoughts or actions may be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes. How can I watch for early symptoms of suicidal thoughts and actions? Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you are worried about symptoms. Do not stop taking XCOPRI without first talking to your healthcare provider. Stopping XCOPRI suddenly can cause serious problems. Stopping a seizure medicine suddenly can cause seizures that will not stop (status epilepticus). XCOPRI is a federally controlled substance (CV) because it can be abused or lead to dependence. Keep XCOPRI in a safe place to prevent misuse and abuse. Tell your healthcare provider if you have ever abused or been dependent on alcohol, prescription medicines, or street drugs. Selling or giving away XCOPRI may harm others and is against the law. What is XCOPRI? XCOPRI is a prescription medicine used to treat partial-onset seizures in adults. It is not known if XCOPRI is safe and effective in children. Do not take XCOPRI if you: are allergic to cenobamate, any of the other ingredients in XCOPRI.

Tell your healthcare provider right away if you become pregnant while taking XCOPRI. You and your healthcare provider will decide if you should take XCOPRI while you are pregnant. If you become pregnant while taking XCOPRI, talk to your healthcare provider about registering with the North American Antiepileptic Drug (NAAED) Pregnancy Registry. The purpose of this registry is to collect information about the safety of antiepileptic medicine during pregnancy. You can enroll in this registry by calling 1-888-233-2334 or go to www.aedpregnancyregistry.org are breastfeeding or plan to breastfeed. It is not known if XCOPRI passes into breastmilk. Talk to your healthcare provider about the best way to feed your baby while taking XCOPRI. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. XCOPRI may affect the way other medicines work, and other medicines may affect how XCOPRI works. Do not start a new medicine without first talking with your healthcare provider. Ask your healthcare provider or pharmacist for a list of medicines you are taking, if you are not sure. Know the medicines you take. Keep a list of them and show it to your healthcare provider and pharmacist when you get a new medicine. How should I take XCOPRI? Take XCOPRI exactly as your healthcare provider tells you to take it. It is very important to increase your dose of XCOPRI slowly, as instructed by your healthcare provider. Do not stop taking XCOPRI without talking to your healthcare provider. Stopping XCOPRI suddenly can cause serious problems, including seizures that will not stop (status epilepticus). Your healthcare provider may change your dose, if needed. Your healthcare provider will tell you how much XCOPRI to take. XCOPRI can be taken at any time of day, with or without food. Swallow tablets whole with liquid. Do not crush or chew.

Clinical Studies
14 CLINICAL STUDIES The efficacy of XCOPRI for the treatment of partial-onset seizures was established in two multicenter, randomized, double-blind, placebo-controlled studies in adult patients (Study 1 and Study 2). Patients enrolled in the studies had partial-onset seizures with or without secondary generalization and were not adequately controlled with 1 to 3 concomitant AEDs. During an 8-week baseline period, patients were required to have at least 3 or 4 partial-onset seizures per 28 days on average with no seizure-free period exceeding 3 to 4 weeks. In these studies, patients had a mean duration of epilepsy of approximately 24 years and median baseline seizure frequency of 8.5 seizures per 28 days. More than 80% of patients were taking 2 or more concomitant AEDs. Study 1 ( NCT01397968 ) compared doses of XCOPRI 200 mg/day with placebo. Study 2 ( NCT01866111 ) compared doses of XCOPRI 100 mg/day, 200 mg/day, and 400 mg/day with placebo. Both studies had an 8-week baseline period to establish a baseline seizure frequency, following which patients were randomized to a treatment arm. Patients entered a treatment period consisting of an initial titration phase (6 weeks), and a subsequent maintenance phase (6 weeks for Study 1 and 12 weeks for Study 2). In Study 1, patients were started on a daily dose of 50 mg (a higher starting dose than currently recommended) and subsequently increased by 50 mg/day every two weeks, until the final daily target dose of 200 mg/day was achieved. In Study 2, patients were started on a daily dose of 50 mg (a higher starting dose than currently recommended) and subsequently increased by 50 mg/day every week (a faster titration than currently recommended) until 100 mg/day or 200 mg/day was reached and then increased by 100 mg/day every week in patients randomized to 400 mg/day [see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.1 ), and Adverse Reactions ( 6.1 )] . The primary efficacy outcome in Study 1 and Study 2 was the percent change from baseline in seizure frequency per 28 days in the treatment period. Table 6 summarizes the results of the primary endpoint for XCOPRI in each study.

Geriatric Use
8.5 Geriatric Use Clinical studies of XCOPRI did not include sufficient numbers of patients aged 65 and over to determine the safety and efficacy of XCOPRI in the elderly population. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy [see Clinical Pharmacology ( 12.3 )] .
Pediatric Use
8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. Juvenile Animal Toxicity Data Cenobamate was administered orally to juvenile rats from postnatal day (PND) 7 to 70. To maintain consistent plasma drug exposures, doses were increased during the dosing period, up to 120 and 80 mg/kg/day in males and females, respectively. Adverse effects included mortality, delayed sexual maturation, neurological (decreased grip strength) and neurobehavioral (learning and memory deficits) impairment, decreased sperm count, decreased brain weight, and ocular histopathology. Recovery from these effects was observed following discontinuation of dosing. Overall, a no-effect dose for adverse effects on postnatal development was not identified. At the lowest doses tested, plasma cenobamate exposures (AUC) were less than that in humans at the maximum recommended human dose (MRHD) of 400 mg.
Pregnancy
8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as XCOPRI, during pregnancy. Encourage women who are taking XCOPRI during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling the toll-free number 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/. Risk Summary There are no adequate data on the developmental risk associated with the use of XCOPRI in pregnant women. In animal studies, administration of cenobamate during pregnancy or throughout pregnancy and lactation resulted in adverse effects on development (increased embryofetal mortality, decreased fetal and offspring body weights, neurobehavioral and reproductive impairment in offspring) at clinically relevant drug exposures [see Data ] . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data Oral administration of cenobamate (0, 10, 30, or 60 mg/kg/day) to pregnant rats during the period of organogenesis resulted in increased embryofetal mortality, reduced fetal body weights, and incomplete fetal skeletal ossification at the highest dose tested, which was associated with maternal toxicity. There was a small increase in visceral malformations at the high dose; however, teratogenic potential could not be fully evaluated because of the high rate of embryofetal deaths, which resulted in an inadequate number of fetuses examined. Maternal plasma exposure (AUC) at the no-effect dose for adverse effects on embryofetal development (30 mg/kg/day) was less than that in humans at the maximum recommended human dose (MRHD) of 400 mg. Oral administration of cenobamate (0, 4, 12, or 36 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in increased embryofetal mortality at the highest dose tested, which was associated with maternal toxicity. Maternal plasma exposure at the no-effect dose (12 mg/kg/day) for adverse effects on embryofetal development was less than that in humans at the MRHD. When cenobamate (0, 11, 22, or 44 mg/kg/day) was orally administered to female rats throughout pregnancy and lactation, neurobehavioral impairment (learning and memory deficit and increased auditory startle response) was observed in the offspring at all doses and decreased preweaning body weight gain and adverse effects on reproductive function (decreased numbers of corpora lutea, implantations, and live fetuses) were seen in the offspring at the high dose. Maternal plasma exposure at the lowest effect dose (11 mg/kg/day) for adverse effects on pre- and postnatal development was less than that in humans at the MRHD.
Use In Specific Populations
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 ) Renal Impairment: Use with caution and dosage reduction may be considered in patients with mild to moderate (CLcr 30 to < 90 mL/min) and severe (CLcr < 30 mL/min) renal impairment. Use not recommended in end-stage renal disease (CLcr < 15 mL/min) undergoing dialysis. ( 8.6 ) Hepatic Impairment: Use with caution in patients with mild to moderate hepatic impairment; lower maximum dosage and additional dosage reduction may be considered. Use of XCOPRI in patients with severe hepatic impairment is not recommended.

Maternal plasma exposure at the lowest effect dose (11 mg/kg/day) for adverse effects on pre- and postnatal development was less than that in humans at the MRHD. 8.2 Lactation Risk Summary There are no data available on the presence of cenobamate in human milk, the effects on the breastfed infant, or the effects of the drug on milk production. Cenobamate was present in rat milk at concentrations similar to those in maternal plasma. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for XCOPRI and any potential adverse effects on the breastfed infant from XCOPRI or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Contraception Women of reproductive potential concomitantly using oral contraceptives should use additional or alternative non-hormonal birth control [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )] . 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.

Use in patients with end-stage renal disease undergoing dialysis is not recommended [see Clinical Pharmacology ( 12.3 )] . 8.7 Hepatic Impairment XCOPRI should be used with caution and in patients with mild to moderate (5-9 points on Child-Pugh assessment; Class A or B) hepatic impairment. In these patients, the maximum recommended dosage is 200 mg once daily and additional dosage reduction may be considered [see Dosage and Administration ( 2.3 ) and Clinical Pharmacology ( 12.3 )] . Use of XCOPRI in patients with severe hepatic impairment is not recommended.
