Acorda Therapeutics Announces European Patent Office Upholds Fampridine (FAMPYRA®) Patent

Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced that the European Patent Office (EPO) Opposition Division has upheld amended claims covering a sustained release formulation of fampridine (known under the trade name FAMPYRA ®), also known as dalfampridine or 4-aminopyridine, for increasing walking speed in patients with MS through twice daily dosing at 10 mg. The decision of the Opposition Division is open to appeal.

“We are pleased that the Opposition Division has recognized the validity of our patent claims for FAMPYRA,” said Ron Cohen, M.D., Acorda’s President and CEO.

This European patent (EP-1 732 548 B) is set to expire in 2025, absent any additional exclusivity granted based on regulatory review timelines. In addition, FAMPYRA received 10-year market exclusivity upon approval by the European Commission that is set to expire in 2021.

FAMPYRA is exclusively developed and commercialized outside the United States by Biogen Idec under a collaboration and licensing agreement with Acorda. FAMPYRA is indicated in the European Union for the improvement of walking in adult patients with multiple sclerosis (MS) with walking disability (EDSS 4-7).

FAMPYRA is the ex-U.S. trade name for AMPYRA ® (dalfampridine) Extended Release Tablets, 10mg, which is being developed and marketed in the United States by Acorda. AMPYRA is an oral medication approved by the U.S. Food and Drug Administration as a treatment to improve walking in patients with MS. This was demonstrated by an increase in walking speed.

In the United States, AMPYRA is covered by multiple patents providing coverage through 2027. In addition, AMPYRA has Orphan drug status providing market exclusivity through January 22, 2017.

AMPYRA Important Safety Information

Do not take AMPYRA if you have ever had a seizure, or have certain types of kidney problems, or are allergic to dalfampridine (4-aminopyridine), the active ingredient in AMPYRA.

Take AMPYRA exactly as prescribed by your doctor.

You could have a seizure even if you never had a seizure before. Your chance of having a seizure is higher if you take too much AMPYRA or if your kidneys have a mild decrease of function, which is common after age 50.

Your doctor may do a blood test to check how well your kidneys are working, if that is not known before you start taking AMPYRA.

AMPYRA may cause serious allergic reactions. Stop taking AMPYRA and call your doctor right away or get emergency medical help if you have shortness of breath or trouble breathing, swelling of your throat or tongue, or hives.

AMPYRA should not be taken with other forms of 4-aminopyridine (4-AP, fampridine), since the active ingredient is the same.

The most common adverse events for AMPYRA in MS patients were urinary tract infection, trouble sleeping, dizziness, headache, nausea, weakness, back pain, and problems with balance.

Before taking AMPYRA tell your doctor if you are pregnant or plan to become pregnant. It is not known if AMPYRA will harm your unborn baby.

Tell your doctor if you are breast-feeding or plan to breast-feed. It is not known if AMPYRA passes into your breast milk. You and your doctor should decide if you will take AMPYRA or breast-feed. You should not do both.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.

About FAMPYRA

FAMPYRA ® is a prolonged-release (sustained release) tablet formulation of the drug fampridine (4-aminopyridine, 4-AP or dalfampridine). FAMPYRA is indicated in the European Union for the improvement of walking in adult patients with multiple sclerosis (MS) with walking disability (EDSS 4-7). In clinical trials the highest incidence of adverse reactions identified with FAMPYRA given at the recommended dose was urinary tract infection, although infection was often not proven by culture. Other adverse drug reactions identified were mainly divided between neurological disorders, such as insomnia, balance disorder, dizziness, paraesthesia, headache and gastrointestinal disorders including nausea, dyspepsia and constipation. In post-marketing experience, there have been reports of seizure. Confounding factors may have contributed to the occurrence of seizure in some patients.
