- Two-year data from more than 62,400 people with multiple sclerosis highlight AMPYRA safety profile
ARDSLEY, N.Y.--(BUSINESS WIRE)-- Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced safety data from more than 62,400 people with multiple sclerosis (MS) taking AMPYRA (dalfampridine) Extended Release Tablets, 10 mg during the first two years of availability in the United States. The data showed that the safety profile of AMPYRA is similar to that observed in clinical trials.
This analysis was presented at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), being held in Lyon, France from October 10-13. AMPYRA is known as prolonged-, modified, or sustained-release fampridine (FAMPYRA®) in some countries outside the United States.
The analysis examined all post-marketing adverse events (AEs) that were reported to Acorda and the U.S. Food and Drug Administration (FDA) from March 2010 through March 2012. As is typical in post-marking data collection, there is a potential for underreporting of AEs. Key findings included:
“AMPYRA has been available for over two years in the United States, providing us with safety data from real-world use by people with MS. These data showed that the safety profile of AMPYRA in clinical practice is consistent with what was observed in clinical trials,” said Enrique Carrazana, M.D., Acorda Therapeutics’ Chief Medical Officer. “The data also indicate the rate of seizure has remained consistent over time, and is within the range that is expected in the overall MS population.”
This poster presentation was sponsored by Acorda Therapeutics, Inc. In markets outside of the United States, AMPYRA is available as FAMPYRA. FAMPYRA is being developed and commercialized by Biogen Idec in these markets based on a licensing agreement with Acorda.
Important Safety Information
Do not take AMPYRA if you have ever had a seizure or have certain types of kidney problems.
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.
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.
