WOODCLIFF LAKE, N.J., Dec. 1, 2021 /PRNewswire/ -- Eisai Inc. announced today that new data on its antiepileptic drug FYCOMPA® (perampanel) CIII will be presented at the 75th American Epilepsy Society (AES) Annual Meeting to be held from December 3 to December 7, 2021 in Chicago, Il. Eisai will present 42 posters including key early add-on FYCOMPA data as well as data in pediatric and elderly patients. Three posters will present data on E2730, a selective uncompetitive GAT-1 Inhibitor, underscoring the company's commitment to advance epilepsy research as part of its mission to help treat patients living with epilepsy.
Key data to be presented include:
- Results from a final analysis of ELEVATE (study 410), a multicenter, open-label Phase IV study evaluating FYCOMPA as monotherapy or first adjunctive therapy in epilepsy patients aged four years and older with focal onset seizures (FOS), with or without focal to bilateral tonic-clonic seizures (FBTCS), or generalized tonic-clonic seizures (GTCS) examining the primary endpoint of retention rate and secondary endpoints of seizure-freedom rate and safety.
- Results from a multicenter, open-label Phase II study (study 238), evaluating the interim safety and efficacy data of adjunctive FYCOMPA as an oral suspension in patients between the ages of greater than 1 to less than 24 months.
- Analyses from the Extension Phase of FREEDOM (study 342), an open-label study assessing FYCOMPA as a monotherapy in epilepsy patients with focal-onset seizures for long-term safety and efficacy, and treatment-emergent adverse events (TEAEs).
- Analyses from AMPA (study 501), a multicenter, prospective, real-life observational study in a clinical setting in Italy, evaluating FYCOMPA in adults and adolescents, for efficacy and safety outcomes as an adjunctive therapy in patients aged greater than 12 with focal-onset seizures, with or without focal to bilateral tonic-clonic seizures.
- An overview of Phase III and Phase IV studies (studies 307, 335, 412, 342 and 506) assessing the efficacy and safety of FYCOMPA in elderly patients greater than 60 years old.
- A real-world global pooled analysis, the PERMIT study, evaluating the effectiveness, safety and tolerability of FYCOMPA in elderly (65 years and greater) epilepsy patients with focal and generalized seizures treated in everyday clinical practice.
- Results from multicenter, open-label Phase IV studies (studies 412 and 410) and multicenter, prospective, real-life, observational study (study 510) evaluating the safety and efficacy of FYCOMPA as a first adjunctive therapy in epilepsy patients with focal-onset seizures or generalized tonic-clonic seizures.
"We are pleased to share data from multiple studies assessing FYCOMPA in a real-world clinical setting, including monotherapy and as an early add-on therapy, as well as seizure reduction and freedom rates across a variety of patient and seizure types at this year's meeting of the American Epilepsy Society," said Ivan Cheung, Chairman, Eisai Inc. and Global President, Neurology Business Group, Eisai Co., Ltd. "At Eisai we continuously work with healthcare providers, caregivers, and patients to better understand the challenges patients with epilepsy experience. These data encourage us to continue our important research to advance our understanding of epilepsy and its treatment."
In September 2018, FYCOMPA was approved by the FDA for monotherapy and adjunctive use in pediatric patients four years and older for the treatment of POS with or without secondarily generalized seizures. The approval includes both the FYCOMPA tablet and oral suspension formulations. To date, FYCOMPA is approved in the United States and Europe and has been used to treat more than 410,000 patients worldwide across all indications.
The following are key studies that will be presented by Eisai at this year's AES Annual Meeting:
Note: Posters will be available at the press room for the duration of the meeting and remain available for 90 days.

INDICATION FOR FYCOMPA
FYCOMPA® (perampanel) is indicated in patients with epilepsy aged 4 years and older for partial-onset seizures (POS) with or without secondarily generalized seizures and adjunctive therapy for patients aged
12 years and older for primary generalized tonic-clonic (PGTC) seizures.
IMPORTANT SAFETY INFORMATION FOR FYCOMPA
WARNING: SERIOUS PSYCHIATRIC AND BEHAVIORAL REACTIONS
- Serious or life-threatening psychiatric and behavioral adverse reactions including aggression, hostility, irritability, anger, and homicidal ideation and threats have been reported in patients taking FYCOMPA
- These reactions occurred in patients with and without prior psychiatric history, prior aggressive behavior, or concomitantuse of medications associated with hostility and aggression
- Advise patients and caregivers to contact a healthcare provider immediately if any of these reactions or changes in mood, behavior, or personality that are not typical for the patient are observed while taking FYCOMPA or after discontinuing FYCOMPA
- Closely monitor patients particularly during the titration period and at higher doses
- FYCOMPA should be reduced if these symptoms occur and should be discontinued immediately if symptoms aresevere or are worsening
SERIOUS PSYCHIATRIC AND BEHAVIORAL REACTIONS
In the partial-onset seizures clinical trials, hostility- and aggression-related adverse reactions occurred in 12% and 20% of patients randomized to receive FYCOMPA at doses of 8 mg and 12 mg per day, respectively, compared to 6% of patients in the placebo group. These effects were dose-related and generally appeared within the first 6 weeks of treatment, although new events continued to be observed through more than 37 weeks. These effects in FYCOMPA-treated patients led to dose reduction, interruption, and discontinuation more frequently than placebo-treated patients. Homicidal ideation and/or threat have also been reported postmarketing in patients treated with FYCOMPA. The combination of alcohol and FYCOMPA significantly worsened mood and increased anger. Patients taking FYCOMPA should avoid the use of alcohol. Patients, their caregivers, and families should be informed that FYCOMPA may increase the risk of psychiatric events. Patients should be monitored during treatment and for at least one month after the last dose of FYCOMPA, and especially when taking higher doses and during the initial few weeks of drug therapy (titration period) or at other times of dose increases. Similar serious psychiatric and behavioral events were observed in the primary generalized tonic-clonic (PGTC) seizure clinical trial.
SUICIDAL BEHAVIOR AND IDEATION
Antiepileptic drugs (AEDs), including FYCOMPA, increase the risk of suicidal thoughts or behavior in patients. Anyone considering prescribing FYCOMPA or any other AED must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, their caregivers, and families should be informed of the risk and advised to monitor and immediately report the emergence or worsening of depression, suicidal thoughts or behavior, thoughts about self-harm and/or any unusual changes in mood or behavior. Should suicidal thoughts and behavior emerge during treatment, consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.
DIZZINESS AND GAIT DISTURBANCE
FYCOMPA caused dose-related increases in events related to dizziness and disturbance in gait or coordination. Dizziness and vertigo were reported in 35% and 47% of patients in the partial-onset seizure trials randomized to receive FYCOMPA at doses of 8 mg and 12 mg per day, respectively, compared to 10% of placebo-treated patients. Gait disturbance related events were reported in 12% and 16% of patients in the partial-onset seizure clinical trials randomized to receive FYCOMPA at doses of 8 mg and 12 mg per day, respectively, compared to 2% of placebo-treated patients. These adverse reactions occurred mostly during the titration phase. These adverse reactions were also observed in the PGTC seizure clinical trial.
SOMNOLENCE AND FATIGUE
FYCOMPA caused dose-dependent increases in somnolence and fatigue-related events. Somnolence was reported in 16% and 18% of patients in the partial-onset seizure trials randomized to receive FYCOMPA at doses of 8 mg and 12 mg per day, respectively, compared to 7% of placebo-treated patients. Fatigue-related events were reported in 12% and 15% of patients in the partial-onset seizure trials randomized to receive FYCOMPA at doses of 8 mg and 12 mg per day, respectively, compared to 5% of placebo-treated patients. These adverse reactions occurred mostly during the titration phase.
These adverse reactions were also observed in the PGTC seizure clinical trial. Patients should be advised against engaging in hazardous activities requiring mental alertness, such as operating motor vehicles or dangerous machinery, until the effect of FYCOMPA is known. Patients should be carefully observed for signs of central nervous system (CNS) depression when FYCOMPA is used with other drugs with sedative properties because of potential additive effects.
FALLS
Falls were reported in 5% and 10% of patients in the partial-onset seizure clinical trials randomized to receive FYCOMPA at doses of 8 mg and 12 mg per day, respectively, compared to 3% of placebo-treated patients.
DRUG REACTION WITH EOSINOPHILIA AND SYSTEMIC SYMPTOMS (DRESS)
DRESS, also known as multiorgan hypersensitivity, has been reported in patients taking AEDs, including FYCOMPA. DRESS may be fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling, in association with other organ system involvement. If signs or symptoms are present, immediately evaluate the patient and discontinue FYCOMPA if an alternative etiology for signs or symptoms cannot be established.
WITHDRAWAL OF AEDs
A gradual withdrawal is generally recommended with AEDs to minimize the potential of increased seizure frequency, but if withdrawal is a response to adverse events, prompt withdrawal can be considered.
MOST COMMON ADVERSE REACTIONS
The most common adverse reactions in patients aged 12 years and older receiving FYCOMPA (≥5% and
≥1% higher than placebo) include dizziness, somnolence, fatigue, irritability, falls, nausea, weight gain, vertigo, ataxia, headache, vomiting, contusion, abdominal pain, and anxiety. Adverse reactions in patients aged 4 to <12 years were generally similar to patients aged 12 years and older.
DRUG INTERACTIONS
FYCOMPA may decrease the efficacy of contraceptives containing levonorgestrel. Plasma levels of perampanel were decreased when administered with known moderate and strong CYP3A4 inducers, including, carbamazepine, phenytoin, or oxcarbazepine. Multiple dosing of FYCOMPA 12 mg per day enhanced the effects of alcohol on vigilance and alertness, and increased levels of anger, confusion, and depression. These effects may also be seen when FYCOMPA is used in combination with other CNS depressants.
PREGNANCY AND LACTATION
Physicians are advised to recommend that pregnant patients taking FYCOMPA enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry. Caution should be exercised when FYCOMPA is administered to pregnant or nursing women as there are no adequate data on the developmental risk associated with use in pregnant women, and no data on the presence of perampanel in human milk, the effects on the breastfed child, or the effects of the drug on milk production.
HEPATIC AND RENAL IMPAIRMENT
Use in patients with severe hepatic or severe renal impairment is not recommended. Dosage adjustments are recommended in patients with mild or moderate hepatic impairment. Use with caution in patients with moderate renal impairment.
DRUG ABUSE AND DEPENDENCE
FYCOMPA is a Schedule III controlled substance and has the potential to be abused and lead to drug dependence and withdrawal symptoms including anxiety, nervousness, irritability, fatigue, asthenia, mood swings, and insomnia.
Please see full Prescribing Information, including Boxed WARNING.
About FYCOMPA
FYCOMPA is a prescription medicine used in people with epilepsy aged 4 and older alone or with other medicines to treat partial-onset seizures with or without secondarily generalized seizures, and with other medicines to treat primary generalized tonic-clonic seizures for people with epilepsy aged 12 and older.
FYCOMPA, a unique oral medication, is a selective, non-competitive AMPA (alpha-amino-3-hydroxy-5- methyl-4-isoxazolepropionic acid) receptor antagonist. The precise mechanism by which FYCOMPA exerts its antiepileptic effects in humans is unknown. In a pharmacokinetic study, it has been demonstrated that because of its long half-life, a missed dose of FYCOMPA does not significantly impact plasma levels.
FYCOMPA is supplied as 2 mg, 4 mg, 6 mg, 8 mg, 10 mg and 12 mg film-coated tablets, and as a 0.5 mg/mL oral suspension formulation. FYCOMPA has been designated by the U.S. Drug Enforcement Administration as a federally-controlled substance (CIII).
About Epilepsy
Epilepsy is a medical condition that produces seizures affecting a variety of mental and physical functions. Epilepsy is one of the most common neurological disorders, which affects about 3.4 million people in the United States, including 470,000 children. Children with uncontrolled seizures are at greater risk for sudden unexpected death in epilepsy (SUDEP), which is relatively uncommon in childhood, but the risk increases if epilepsy persists into adulthood.
Partial-onset seizures are the most common type of seizure seen in people with epilepsy, accounting for 60 percent of all seizures. Convulsive seizures account for up to 25 percent of all epilepsy, with primary generalized tonic-clonic seizures being one of the most common and severe forms of seizures.
Missed medication doses are the number one cause of breakthrough seizures, which can cause significant injury to patients. People who experience breakthrough seizures have an increased risk of fractures or head injuries, emergency room (ER) visits, and hospitalization, as well as an associated increase in healthcare costs.
