Acorda Announces Initiation of Phase 3 Clinical Trial for Dalfampridine in Post-Stroke Walking Deficits


ARDSLEY, N.Y.--(BUSINESS WIRE)-- Acorda Therapeutics, Inc. (Nasdaq:ACOR) today announced that the first patient has been enrolled in a Phase 3 clinical trial of dalfampridine for the treatment of post-stroke walking deficits (PSWD).

“Approximately three and a half million stroke survivors in the U.S. suffer ongoing mobility issues. This is a significant unmet medical need, as there are no approved medicines to improve walking in people with PSWD,” said Ron Cohen, M.D., Acorda Therapeutics' President and CEO. “Our Phase 2 trial of dalfampridine in PSWD produced promising data, showing significant improvements in walking speed. This larger Phase 3 trial will enroll a similar patient population, and include a number of assessments to evaluate the effect of dalfampridine in improving their walking.”

This multi-center, double-blind, randomized trial is expected to enroll approximately 540 participants who have experienced an ischemic stroke at least six months prior to enrollment. Participants will receive 10 mg dalfampridine, 7.5 mg dalfampridine, or placebo twice daily for 12 weeks. The primary endpoint of the study is the percentage of patients taking dalfampridine who demonstrate at least a 20% improvement in the 2 Minute Walk Test (2MinWT) compared to those receiving placebo. The 2MinWT measures the distance a person can walk in 2 minutes. Other measures will include the Timed Up and Go, which assesses mobility and balance, as well as clinician and patient-reported measures. The study also includes evaluation of safety and tolerability.

Phase 2 Study Results

In April 2013, the Company announced results from a Phase 2 study which showed participants had a significantly greater improvement in walking speed when receiving dalfampridine over two weeks of treatment than when receiving placebo, as measured by the Timed 25-Foot Walk test (T25FW). Safety findings for the study were consistent with previous clinical trials and post-marketing experience of dalfampridine in people with multiple sclerosis.

About Stroke

About 800,000 new cases of stroke occur annually in the U.S. Approximately 3.5 million stroke survivors in U.S. have ongoing mobility issues, and there are no currently approved medications for such impairments.

Dalfampridine Important Safety Information

Dalfampridine is the active ingredient in AMPYRA® (dalfampridine) Extended Release Tablets, 10 mg, approved by the FDA as a treatment to improve walking in patients with multiple sclerosis (MS). This was demonstrated by an increase in walking speed. Dalfampridine extended release tablets have not been evaluated by FDA for the treatment of post-stroke deficits.

The FDA-approved form of dalfampridine (AMPYRA) is contraindicated in patients with a history of seizures, or with moderate or severe renal impairment, or history of hypersensitivity to dalfampridine or 4-aminopyridine.

Dalfampridine can cause seizures. The risk of seizures increases with increasing dalfampridine doses. Discontinue dalfampridine and do not restart if seizure occurs.

Dalfampridine 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 dalfampridine in MS patients were urinary tract infection, trouble sleeping, dizziness, headache, nausea, weakness, back pain, and problems with balance.
