Acorda Therapeutics Announces Filing Of Patent Extension Applications For AMPYRA™ (dalfampridine)

Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced that the Company has submitted applications to extend patent protection for AMPYRA™ (dalfampridine) Extended Release Tablets, 10 mg to the United States Patent and Trademark Office (USPTO).

AMPYRA was approved by the U.S. Food and Drug Administration (FDA) on January 22, 2010 and has seven years of exclusivity in multiple sclerosis (MS) based on orphan drug status, which has been confirmed by the FDA. Acorda has applied to extend two AMPYRA patents listed in the FDA Orange Book based on provisions in the Hatch Waxman Act that allow for up to five additional years of patent protection based on the development timeline of a drug. These patents currently expire on December 6, 2011 and July 30, 2013. If both are granted, the Company will need to select one patent for extension.

AMPYRA is now available by prescription in the United States. For more information about AMPYRA, including patient assistance and co-pay programs, healthcare professionals and people with MS can contact AMPYRA Patient Support Services at 888-881-1918.

AMPYRA Patient Support Services is available from 8:00 a.m. to 8:00 p.m. Eastern Time at 888-881-1918. For full U.S. Prescribing Information and Medication Guide, please visit: www.AMPYRA.com.

Important Safety Information

AMPYRA can cause seizures; the risk of seizures increases with increasing AMPYRA doses. AMPYRA is contraindicated in patients with a prior history of seizure. Discontinue AMPYRA use if seizure occurs.

AMPYRA is contraindicated in patients with moderate or severe renal impairment (CrCl≤50 mL/min); the risk of seizures in patients with mild renal impairment (CrCl 51–80 mL/min) is unknown, but AMPYRA plasma levels in these patients may approach those seen at a dose of 15 mg twice daily, a dose that may be associated with an increased risk of seizures; estimated CrCl should be known before initiating treatment with AMPYRA.
