Sep 18, 2013, 09:00 ET from Sunovion Pharmaceuticals Canada Inc.

MISSISSAUGA, ON, Sept. 18, 2013 /CNW/ - Sunovion Pharmaceuticals Canada Inc. (Sunovion) today announced that Health Canada has accepted for review the company's New Drug Submission (NDS) for eslicarbazepine acetate for use as a once-daily adjunctive therapy in the treatment of partial-onset seizures in patients 18 years of age and older with epilepsy. The efficacy and safety of eslicarbazepine acetate as an adjunctive or monotherapy treatment for partial-onset seizures in adults living with epilepsy has not yet been established.

"The acceptance of our eslicarbazepine acetate submission is an important milestone not only for our company, but for thousands of Canadians living with and affected by epilepsy," said Douglas Reynolds, President, Sunovion Pharmaceuticals Canada Inc. "Adequate seizure control remains an unmet medical need for a significant number of patients and Sunovion is committed to providing a treatment option to address this need. If approved, eslicarbazepine acetate may offer adult patients an effective, adjunctive treatment option for better managing partial-onset seizures".

The NDS for eslicarbazepine acetate is supported by data from three Phase III randomized, double-blind, placebo-controlled 12-week maintenance trials of similar study design, which included more than 1,400 patients with partial-onset seizures. In these trials, treatment with eslicarbazepine acetate demonstrated statistically significant reductions in standardized seizure frequency when used as adjunctive therapy. The most commonly reported adverse events in the clinical trials were dizziness, somnolence, headache, nausea, diplopia, vomiting, fatigue, ataxia, blurred vision and vertigo.

About Partial-Onset Seizures
Epilepsy is one of the most common neurological disorders1 and is characterized by recurrent seizures, with abnormal firing of impulses from nerve cells in the brain2. In partial-onset seizures, the abnormal electrical activity begins in specific areas of the brain, but may become more widespread, with symptoms varying according to the affected areas3,4.

About Eslicarbazepine Acetate 
Eslicarbazepine acetate is an investigational voltage-gated sodium and T-type calcium channel blocker that has been evaluated in three Phase III clinical trials involving more than 1,400 patients with partial-onset seizures worldwide. The initial research and development of eslicarbazepine acetate was performed by BIAL-Portela & Ca, S.A., a privately held Portuguese research based pharmaceutical company. Subsequently, Sunovion Pharmaceuticals Inc., acquired the rights to further develop and commercialize eslicarbazepine acetate in the U.S. and Canadian markets from BIAL.
