Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent Application No. 8,440,703 (“the ‘703 patent”) entitled “Methods of Using Sustained Release Aminopyridine Compositions.” The ‘703 patent includes claims directed to methods of improving lower extremity function and walking and increasing walking speed in patients with multiple sclerosis (MS) by administering less than 15 mg of sustained release 4-aminopyridine (dalfampridine) twice daily.

The ‘703 patent is set to expire in 2025. This patent is eligible for listing in the U.S. Food and Drug Administration (FDA) Orange Book.

The ‘703 patent is separate from the two AMPYRAmethod of use patents issued by the USPTO in 2011 and 2013 that are set to expire in 2027 and 2026, respectively.

AMPYRA is approved in the United States as a treatment to improve walking in patients with multiple sclerosis (MS). This was demonstrated by an improvement in walking speed. AMPYRA is known as prolonged-, modified-, or sustained-release fampridine (FAMPYRA) in some countries outside the United States.

Do not take AMPYRA if you are allergic to dalfampridine (4-aminopyridine), the active ingredient in AMPYRA.

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, including rare occurrence of anaphylaxis. 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 , or call 1-800-FDA-1088.
