Data presented at the American Epilepsy Society annual meeting
provide insights into initiating and monitoring intravenous
treatment, and smoothly transitioning patients to oral Vimpat
ATLANTA, Dec. 7 /PRNewswire-FirstCall/ -- Results of two new
studies support the use of the intravenous formulation of the
antiepileptic drug (AED) Vimpat® for patients requiring add-on
therapy in clinical settings where oral AED therapy is temporarily
not feasible. These data, which were presented by UCB at the 63rd
annual meeting of the American Epilepsy Society in Boston, further
clarify the role of intravenous Vimpat in the institutional
setting. One study shows that patients can be transitioned from
intravenous Vimpat to the oral formulation, while maintaining
steady, therapeutic plasma levels. "This study shows that
intravenous Vimpat is generally well tolerated across a range of
doses and infusion durations as a replacement for oral therapy in
add-on epilepsy therapy. This will help patients receive Vimpat in
clinical settings where administration of an oral epilepsy therapy
is not possible, such as emergency rooms or those related to
surgery," said study author Gregory Krauss, MD, Department of
Neurology, Johns Hopkins Epilepsy Center in Baltimore, MD. "This
study helps clinicians understand what to expect when initiating
and monitoring intravenous treatment in patients who are
Vimpat-naive or who need to substitute oral Vimpat with an
intravenous formulation." A second study provides data on
administration of a single intravenous loading dose of Vimpat over
15 minutes, followed by the equivalent daily oral dose administered
twice daily. Vimpat was launched in the U.S. in May 2009 as an
add-on therapy for the treatment of partial-onset seizures in
people with epilepsy who are 17 years and older. Vimpat has a novel
mechanism of action that is different from all currently available
AEDs. Vimpat is available as oral tablets and as an intravenous
(IV) infusion to allow for consistent treatment in a hospital or
emergency setting. Vimpat can be initiated with either oral or
intravenous administration. The initial dose should be 50 mg twice
daily (100 mg per day). Vimpat can be increased weekly by 100
mg/day, given as two divided doses, up to the recommended
maintenance dose of 200 to 400 mg/day. 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 to
60 minutes. 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. Summary of Intravenous Vimpat Data Presented at
2009 AES Annual Meeting Abstract: Pharmacokinetic evaluation of
intravenous lacosamide as short-term replacement for oral
lacosamide in partial-onset seizures In this 160-patient analysis
of the lacosamide long-term open-label extension trial, patients
receiving oral lacosamide were converted to therapeutically
equivalent intravenous doses, and grouped into three cohorts based
on infusion duration. Results showed that intravenous lacosamide
provided similar plasma concentrations as those associated with
oral lacosamide, across consecutive dosing days and regardless of
infusion durations. -- Average Ctrough and Cmax plasma
concentrations (minimum and maximum concentrations of a drug in the
body after dosing) for oral and intravenous lacosamide appeared
dose-proportional across consecutive dosing days within a
therapeutic dose range. -- Plasma concentration levels were similar
across all cohorts. Poster Session 2, Sunday, December 6, 4:00 pm -

States Abstract: A multicenter, open-label trial to assess the
safety and tolerability of a single intravenous loading dose of
lacosamide followed by oral maintenance as adjunctive therapy in
subjects with partial-onset seizures: an interim report In this
study, patients currently taking one to two AEDs were grouped into
three, 25-patient cohorts and given three progressively increasing
doses of intravenous lacosamide (200 mg, 300 mg and 400 mg)
administered via 15-minute infusions, followed by the same dose of
the oral form given twice-daily for 6.5 days. The first three
cohorts (200 mg, 300 mg and 400 mg loading dose) have completed the
trial. All subjects in the first cohort (200 mg loading dose)
completed the trial. One subject (4 percent) from the second cohort
(300 mg loading dose) and four subjects (16 percent) from the third
cohort (400 mg loading dose) withdrew due to adverse events. Based
on results of these cohorts, enrollment of the fourth repeat cohort
will proceed with the highest well-tolerated loading dose.
Additional data on safety and tolerability will be presented during
the poster session at AES. Poster Session 2, Sunday, December 6,

Important safety information about Vimpat® in the U.S. Vimpat®
(lacosamide) is a medicine that is used with other medicines to
treat partial-onset seizures in patients 17 years of age and older
with epilepsy. Vimpat® is generally well-tolerated, but may not be
for everyone. Patients should discuss with their doctor if Vimpat®
is right for them. The most common side effects with Vimpat® are
dizziness, headache, nausea and double vision. Vimpat® may also
cause problems with coordination and balance. Patients should not
drive, operate machinery or do other dangerous activities until
they know how Vimpat® affects them. Patients should not stop taking
Vimpat® without first talking to their doctor. Stopping Vimpat®
suddenly can cause serious problems. Vimpat® could make patients
feel faint. Patients should tell their doctor if they have a heart
condition or if they are taking other medicines that affect the
heart. In rare cases, Vimpat® may cause reactions that could affect
the heart, liver or kidney. The patient should contact their doctor
immediately if they are tired, have jaundice (yellowing of skin or
eyes), and have dark urine. Antiepileptic drugs, including Vimpat®,
may cause suicidal thoughts or actions in a very small number of
people, about 1 in 500. Patients should call their healthcare
provider right away if they have new or worsening symptoms of
depression, any unusual changes in mood or behavior, or suicidal
thoughts, behavior, or thoughts about self harm that they have
never had before or may be worse than before. To report SUSPECTED
