XCOPRI® (cenobamate tablets) CV patient, Laura

Laura, not giving up after diagnosis

Before XCOPRI: 1-2 seizures/month, 5 ASMs
After starting XCOPRI: 1 seizure/6 months, 1 ASM + XCOPRI 100 mg

I want to let people know there is life after being diagnosed with epilepsy.”

Laura first started having nocturnal seizures at 57 years old. After diagnosis, she was forced into early retirement and feared epilepsy would prevent her from the vibrant social life she loved.

Now on XCOPRI, Laura is getting back to what matters most: her family, sports games, and rock and roll.

XCOPRI® (cenobamate tablets) CV patient, Shannon

Shannon, back to work

Before XCOPRI: 1 seizure/month, 2 ASMs
After starting XCOPRI: 0 seizures/month, 1 ASM + XCOPRI 100 mg

Don’t be afraid to ask. Don’t be afraid to try a different medication because XCOPRI thankfully worked for me.”

After an accident led to his epilepsy diagnosis in his mid-30s, Shannon struggled with embarrassment—especially when seizures happened at work or in front of his children.

With XCOPRI, Shannon has reclaimed his independence. He is back to his job as an airport terminal superintendent and enjoying cherished date nights with his daughters.

XCOPRI® (cenobamate tablets) CV patient, Koral

Koral, a teacher and advocate

Before XCOPRI: daily seizures, 4 ASMs
After starting XCOPRI: 1 seizure/month, XCOPRI 200 mg

With those reductions, I feel like I’m in charge of my life again. Don’t ever settle for anything less than you deserve.”

Koral started having seizures in high school and spent years undiagnosed, battling multiple seizures a day while trying to keep up a normal teenage life.

Since starting XCOPRI, her seizure frequency has dramatically decreased. Today, Koral is back in college and continuing to pursue her passion as a teacher for children with autism.

Frequently asked questions

Explore answers to common questions about XCOPRI.

The International League Against Epilepsy considers a person to have epilepsy if they meet any of the following conditions1:

  1. At least 2 unprovoked (or reflex) seizures occurring greater than 24 hours apart
  2. Diagnosis of an epilepsy syndrome
  3. One unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after 2 unprovoked seizures, occurring over the next 10 years

A seizure is an abnormal paroxysmal discharge of neurons.2 There are some things that can trigger seizures in patients with epilepsy. They include sleep deprivation, stress, fever, alcohol binging, use of recreational drugs, and use of some prescribed and/or over-the-counter medications.3

Seizures affect people differently, and there are several types of seizures. Seizures may come in 3 distinct phases, with a beginning, middle, and end. Some people experience an aura or other warning signs that a seizure is coming on, including dizziness, headache, nausea, or altered senses or emotions. During the middle of the seizure, some people lose consciousness or feel confused and/or experience tremors or can’t move at all, among many other possible symptoms. At the end, they may feel sleepy, scared, confused, or embarrassed, and/or they may have a headache, nausea, or weakness, to name a few symptoms.4

Most seizures last between 30 seconds and 2 minutes. However, depending on the type of seizure, it can be shorter or substantially longer. A seizure that lasts longer than 5 minutes is a medical emergency.5

Keep the person safe and call for medical help if the seizure continues for a prolonged period of time (longer than 5 minutes). After the seizure is over, stay with them or see them home safely.6

A partial-onset seizure, also known as a focal seizure, starts in one part of the brain and may stay there or may spread. This is different from a generalized seizure, which starts in both hemispheres of the brain at the same time.7

XCOPRI is indicated for the treatment of partial-onset seizures in adult patients, meaning 18 years and older. There are ongoing trials for the pediatric population, but safety and effectiveness in pediatric patients have not been established at this time.8

For additional information, please review the full Prescribing Information for XCOPRI.

Sample packs are available in 12.5 mg (weeks 1-2) and 25 mg (weeks 3-4).

Patients saw significant reductions in overall seizure frequency during clinical trials, with as many as 1 in 5 patients achieving ZERO SEIZURES during the maintenance phase.8

The top 5 were levetiracetam, lamotrigine, lacosamide, carbamazepine/oxcarbazepine, and topiramate.8-10

Study 2 had a 6-week titration phase and a 12-week maintenance phase. The primary endpoint for each dose included all 18 weeks of treatment. Based on the titration schedule in that study, subjects in the 400 mg group did not reach their target dose of 400 mg until the beginning of the maintenance phase. However, there is a clear dose response (400 mg better than 200 mg) for subjects having a response of 75% to 100% during the maintenance phase.8

A statistical significance in the primary endpoint was demonstrated with 100 mg. Based on the current recommended starting dose and titration, 100 mg is reached at 6 weeks.8

For safety information related to XCOPRI, please see the XCOPRI full Prescribing Information.

XCOPRI should be used with caution, and dosage reduction may be considered in patients with mild to moderate (CLcr 30 to less than 90 mL/min) and severe (CLcr less than 30 mL/min) renal impairment. Use in patients with end-stage renal disease undergoing dialysis is not recommended.8

See the XCOPRI full Prescribing Information.

For patients with mild to moderate (5-9 points on the Child-Pugh assessment; Class A or B) hepatic impairment, the maximum recommended dosage is 200 mg once daily. XCOPRI is not recommended for use in patients with severe hepatic impairment.8

See the XCOPRI full Prescribing Information.

Familial Short QT syndrome is a life-threatening, inherited heart disease. In an article published in Heart Rhythm journal in 2018, which featured a review of papers published from 2000-2017, there were 220 patients identified with familial QT shortening.11

As per the XCOPRI full Prescribing Information, there is no recommendation to perform an electrocardiogram (EKG) prior to or during XCOPRI use.8

After the Food and Drug Administration (FDA) and Drug Enforcement Administration (DEA) review of the cenobamate New Drug Application (NDA), it was concluded that cenobamate has a relative abuse potential lower than substances in Schedule IV but greater than placebo and should be placed into Schedule V of the Controlled Substances Act.8

XCOPRI is a once-daily pill that is titrated in 2-week intervals and available in 6 tablet strengths.8

See the XCOPRI full Prescribing Information for complete information on how patients should take XCOPRI.

XCOPRI can be prescribed as monotherapy or adjunctive therapy.8

In clinical trials, the top 5 concomitant epilepsy medications used with XCOPRI were levetiracetam, lamotrigine, lacosamide, carbamazepine/oxcarbazepine, and topiramate.8-10

As per the XCOPRI full Prescribing Information, because of the potential for reduced efficacy of oral contraceptives, women should use additional or alternative nonhormonal birth control while taking XCOPRI.8

A list of drug interactions is provided in Section 7.1 of the XCOPRI full Prescribing Information. It is important to be aware of the potential emergence of side effects early in the XCOPRI titration with clobazam, phenytoin, and phenobarbital.8

IMPORTANT SAFETY INFORMATION and INDICATION for XCOPRI® (cenobamate tablets) CV

CONTRAINDICATIONS

XCOPRI is contraindicated in patients with hypersensitivity to cenobamate or any of the ingredients in the product. 

XCOPRI is contraindicated in patients with Familial Short QT syndrome.

WARNINGS AND PRECAUTIONS

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Also known as Multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including XCOPRI. DRESS has been reported, including one fatality, when XCOPRI is titrated rapidly (weekly or faster titration). No cases of DRESS were reported in an open-label safety study of 1339 partial-onset seizure patients when XCOPRI was initiated at 12.5 mg/day and titrated every two weeks. This finding does not establish that the risk of DRESS is prevented by a slower titration; however, XCOPRI should be initiated at 12.5 mg once daily and titrated every two weeks. DRESS typically, although not exclusively, presents with fever, rash, and/or lymphadenopathy, in association with other organ system involvement. Eosinophilia is often present. If such signs or symptoms are present, the patient should be evaluated immediately. XCOPRI should be discontinued immediately and not restarted if an alternative etiology for the signs or symptoms cannot be established.

QT Shortening: XCOPRI can cause shortening of the QT interval. Caution should be used when administering XCOPRI and other drugs that shorten the QT interval as there may be a synergistic effect on the QT interval that would increase the QT shortening risk.

Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including XCOPRI, 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. Advise patients, their caregivers, and/or families to be alert for these behavioral changes and report them immediately to a healthcare provider.

Liver Injury: Clinically significant liver injury has occurred in patients taking XCOPRI. Obtain serum transaminases (ALT and AST) and total bilirubin, if not recently available (i.e., within 3 months) before initiating XCOPRI, and during treatment if clinically indicated. Monitor patients for signs and symptoms of any hepatic injury during treatment. Discontinue XCOPRI in patients with evidence of liver injury in the absence of an alternative etiology.

Neurological Adverse Reactions: XCOPRI can cause dose-dependent increases in the neurologic adverse reactions including dizziness, diplopia, disturbance in gait and coordination, somnolence, and fatigue.

Prescribers should advise patients against engaging in hazardous activities requiring mental alertness, such as operating motor vehicles or dangerous machinery, until the effect of XCOPRI is known.

Withdrawal of AEDs: As with all antiepileptic drugs, XCOPRI should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus. If withdrawal is needed because of a serious adverse event, rapid discontinuation can be considered.

MOST COMMON ADVERSE REACTIONS

In adult adjunctive therapy placebo-controlled clinical studies, the most common adverse reactions that occurred in XCOPRI-treated patients (incidence at least 10% and greater than placebo) were somnolence, dizziness, fatigue, diplopia, headache.

DOSING CONSIDERATIONS

Dosage adjustment of XCOPRI or other concomitant medications may be necessary.

  • Consider gradually reducing phenytoin dosages by up to 50% during initial titration.
  • Consider reducing dosages of phenobarbital and clobazam as needed when used concomitantly with XCOPRI.
  • When XCOPRI and carbamazepine or lamotrigine are taken concomitantly, consider increasing dosages as needed of carbamazepine or lamotrigine.
  • Consider increasing dosages as needed of drugs which are CYP2B6 and CYP3A substrates and decreasing dosages as needed of drugs which are CYP2C19 substrates.
  • Effectiveness of hormonal oral contraceptives may be reduced when administered concomitantly with XCOPRI. Women should use additional or alternative non-hormonal birth control.

Dosage reduction of XCOPRI may be considered in patients with mild to moderate and severe renal impairment. XCOPRI is not recommended in end-stage renal disease.

The maximum recommended daily dose is 200 mg for patients with mild or moderate hepatic impairment. XCOPRI is not recommended in patients with severe hepatic impairment.

DRUG ABUSE

XCOPRI is a Schedule V controlled substance.
