Acorda Therapeutics and FDA Reach Agreement on Special Protocol Assessment for Second Phase 3 Study of Fampridine-SR in Multiple Sclerosis

HAWTHORNE, N.Y.--(HSMN NewsFeed)--Acorda Therapeutics, Inc. (Nasdaq: ACOR ) today announced that it has reached agreement with the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) for a second Phase 3 trial of Fampridine-SR in Multiple Sclerosis (MS). An SPA is a process in which the FDA provides evaluation and guidance on clinical trial protocols for Phase 3 trials. The objective of the study is to show that individuals treated with Fampridine-SR are significantly more likely to have consistent improvements in their walking than those treated with placebo. Pending clinical results, the FDA has agreed that this trial, MS-F204, together with the company's first Phase 3 trial, MS-F203, would be adequate to support a New Drug Application (NDA) for Fampridine-SR.

"We are pleased to have reached this agreement with the FDA, and are already working closely with our team of 35 MS centers to begin the study," said Ron Cohen, M.D., President and CEO. "Currently, there are no approved therapies that improve mobility in people with MS and physicians and patients regularly rate walking as one of the areas of greatest unmet medical need for this condition."

MS-F204 Trial Design

The primary outcome measure for the study will be a walking response, defined as a consistent improvement in walking speed as measured by the Timed 25-Foot Walk. Efficacy will be based solely on the achievement of statistical significance in the primary outcome measure. The secondary outcome measure for this study is the Lower Extremity Manual Muscle Test (LEMMT). Additional outcome measures, such as the Ashworth score for spasticity, a Clinician Global Impression and a Subject Global Impression, are included to allow an integrated efficacy analysis across studies. A visit at the conclusion of the study will provide pharmacodynamic information. Approximately 35 MS centers in the U.S. and Canada are expected to participate in the trial, and the trial is designed to enroll approximately 200 participants.

The design of MS-F204 is fundamentally similar to Acorda's first Phase 3 trial of Fampridine-SR in MS, MS-F203. However, the current study protocol will require 14 weeks of patient participation compared to 21 weeks in MS-F203.
