Refuse to File Letter from FDA for Fampridine-SR NDA

Acorda Therapeutics Receives Refuse to File Letter from FDA on Fampridine-SR NDA

HAWTHORNE, N.Y.-- Mar 31, 2009 - Acorda Therapeutics, Inc. announced today that the Company received a refuse to file letter from the U.S. Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for Fampridine-SR, a novel therapy being developed to improve walking ability in people with multiple sclerosis (MS).

The FDA has raised what it termed "format issues" regarding the eCTD (electronic) submission, requesting that some of the data in the NDA be reformatted, as well as requesting that some additional supporting information be included in the filing. The FDA has not requested or recommended additional clinical or other studies.

"We are surprised by this development," stated Ron Cohen, M.D., President and CEO of Acorda Therapeutics, "We plan to address the issues raised in this letter with FDA expeditiously as we believe Fampridine-SR is potentially an important, first in class treatment option for people suffering with MS."

The Company plans to request a meeting with FDA as soon as possible to discuss its comments on the NDA filing.
