HATFIELD, England, January 7, 2013 /PRNewswire/ --

Eisai today launches Fycompa ^® (perampanel) in Norway as a treatment for
partial-onset seizures, with or without secondarily generalised seizures, in
people with epilepsy aged 12 years and older. ^[1] Perampanel is the first in
an entirely new class of treatment for uncontrolled partial epilepsy, the most
common form of the condition.

There are more than 45,000 people in Norway with epilepsy. ^[ ^2] The
successful treatment of partial-onset seizures remains a significant challenge
in some patients and the incidence of uncontrolled partial epilepsy remains
high despite the availability of many anti-epileptic drugs (AEDs). Currently,
between 20 - 40% of patients with newly diagnosed epilepsy will become
refractory to treatment. ^[3]

Perampanel is the first and only licensed AED to selectively target AMPA
receptors, a protein in the brain which plays a critical role in causing
seizures. ^[4] This mechanism of action is different to other, currently
available AEDs. In addition, perampanel has the added benefit of convenient,
once-daily dosing at bedtime ^[ ^1 ^] and, significantly, is the only
new-generation partial epilepsy treatment approved to treat adolescents with
epilepsy from launch.

"Doctors and patients in Norway will welcome perampanel as a new option for
the treatment of partial onset epilepsy. Itmay help people living with
epilepsy to achieve better seizure control," said dr. Karl Otto Nakken from
the National Center for Epilepsy, Oslo university hospital. "Perampanel could
also help to optimise adherence in patients through once daily dosing, and
thereby improve outcomes for these patients and reduce the potential drug
burden a person with epilepsy may experience."

The efficacy, safety and tolerability of perampanel have been demonstrated by
three Phase III global, randomised, double-blind, placebo-controlled,
dose-escalation studies in 1,480 epilepsy patients. They showed consistent
results in the efficacy and tolerability of perampanel as an adjunctive
therapy in people with partial-onset seizures (with or without secondary
generalisations). ^[5] ^, ^[6] ^, ^[7] The most commonly reported adverse
events were dizziness, somnolence, fatigue, headache, falls, irritability and
ataxia. ^[ ^5 ^] ^, ^[ ^6 ^] ^, ^[ ^7 ^] ^

The Norwegian price for perampanel was received from the Norwegian Board of
Health Supervision on 15 November 2012. Perampanel received CHMP positive
opinion in May 2012, was approved by the EC on 23 July 2012 and first launched
in the UK on 13 September 2012. The FDA accepted the resubmission of New Drug
Application for perampanel in March 2012 and has assigned a Prescription Drug
User Free Act (PDUFA) target date of 22 October 2012.

The development of perampanel underscores Eisai's human health care  (hhc)
mission, the company's commitment to innovative solutions in disease
prevention, cure and care for the health and well being of people worldwide.
Eisai is committed to the therapeutic area of epilepsy and addressing the
unmet medical needs of patients with epilepsy and their families. Eisai is
proud to currently market more epilepsy products in Europe, the Middle East,
Africa and Russia (EMEA) than any other company.

Notes to Editors

About perampanel

Perampanel is a highly selective, non-competitive AMPA
(alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid)-type glutamate
receptor antagonist that has demonstrated seizure reduction in Phase II and
III studies. AMPA receptors, widely present in almost all excitatory neurons,
transmit signals stimulated by the excitatory neurotransmitter glutamate
within the brain and are believed to play a role in central nervous system
diseases characterised by excess neuroexcitatory signalling including
epilepsy, neurodegenerative disorders, movement disorders, pain and
psychiatric disorders. ^[ ^1 ^]

About the Perampanel pooled data (Study 306, 305 and 304)

The pooled Phase III data analysed the efficacy of once-daily perampanel in
reducing partial-onset seizures, the most common form of epilepsy, and its
effectiveness and flexibility of use as add-on therapy. Perampanel is licensed
for the adjunctive treatment of partial-onset seizures with or without
secondarily generalized seizures in patients with epilepsy. The Scottish
Medicines Consortium (SMC) considers perampanel when positioned for use as a
second-line adjunctive treatment in patients with refractory partial onset
epilepsy i.e. patients who have previously received monotherapy and are not
seizure free after at least one other adjunctive therapy.

Results from two separate analyses of pooled data from the perampanel pivotal
Phase III clinical trial programme endorse the efficacy and safety of the new
AED at clinically relevant doses. ^[8] In addition, the results show that
perampanel decreased the frequency of both complex partial seizures and
secondarily generalised seizures. ^[9] In a third analysis of the pooled trial
data, patients with uncontrolled partial-onset seizures taking any of the five
most commonly-used AEDs with perampanel as an add-on therapy experienced a
reduction in their seizure frequency. Patients generally received additional
benefit from increased doses of perampanel. ^[10]

The clinical development plan for perampanel consisted of three global Phase
III studies (studies 306, 305 and 304). The key goal of Study 306 ^[ ^5 ^] was
to identify the minimal effective dose and included four treatment arms
(placebo, 2mg, 4mg, and 8mg). Study 304 ^[ ^6 ^] and Study 305 ^[ ^7 ^]
included three arms (placebo, 8mg, and 12mg) and were to evaluate a more
extended dose range. The studies were similar in design: global, randomised,
double-blind, placebo-controlled, dose-escalation, parallel-group studies. The
primary and secondary endpoints were the same in all the studies: percentage
change in seizure frequency, 50% responder rate, percentage reduction of
complex partial plus secondarily generalised seizures, and evaluation for dose
response. The primary endpoint for the EMA is 50% responder rate and for the
FDA is median percent change in seizure frequency.

About Epilepsy

Epilepsy is one of the most common neurological conditions in the world,
affecting approximately eight in 1,000 people in Europe, and an estimated 50
million people with the condition worldwide. ^[11] ^, ^[12] Epilepsy is a
chronic disorder of the brain that affects people of all ages. It is
characterised by abnormal discharges of neuronal activity causing seizures.
Seizures can vary in severity, from brief lapses of attention or jerking of
muscles, to severe and prolonged convulsions. Depending on the seizure type,
seizures may be limited to one part of the body, or may involve the whole
body. Seizures can also vary in frequency from less than one per year, to
several per day. Epilepsy has many possible causes but often the cause is
unknown.
