Update: Ampyra (formerly Fampridine-SR) Now FDA Approved - January 22, 2010
Positive Vote by FDA Advisory Committee for Fampridine-SR
Acorda Therapeutics Announces Positive Vote by FDA Advisory Committee for Fampridine-SR
HAWTHORNE, N.Y.--(BUSINESS WIRE)--Oct 14, 2009 - Acorda Therapeutics, Inc. today announced the U.S. Food and Drug Administration (FDA) Peripheral and Central Nervous System Drugs (PCNSD) Advisory Committee voted 12 to 1 that clinical data on Fampridine-SR 10 mg twice daily demonstrated substantial evidence of effectiveness as a treatment to improve walking in people with multiple sclerosis (MS) and voted 10 to 2 (1 abstention) that it is clinically meaningful and can be safe for use.
"We are pleased with the outcome of today's Advisory Committee meeting. People with MS have an urgent need for therapies to improve their walking, which is essential to conducting their activities of daily life. If approved, Fampridine-SR would be the first medicine to improve walking in people with MS," said Ron Cohen, M.D., Acorda Therapeutics President and CEO. "This Advisory Committee meeting is an important milestone in the development of Fampridine-SR, and we look forward to working with the FDA as it completes its review of Acorda's New Drug Application."
The Committee also recommended by a vote of 12 to 1 that Acorda be required to evaluate the effects of doses lower than 10 mg twice daily, but by a 10 to 2 vote (1 abstention) that these studies not be required prior to approval.
At the request of the FDA, the Committee discussed possible conditions for use, including for patients with renal impairment or history of seizure. Acorda has proposed a Risk Evaluation and Mitigation Strategy (REMS) program, which could include healthcare professional and patient education around appropriate use of Fampridine-SR.
The FDA seeks the advice of an advisory committee such as the PCNSD when evaluating a potential new treatment, but is not required to follow its recommendation. The current Fampridine-SR Prescription Drug User Fee Act (PDUFA) date set by the FDA is October 22, 2009; the PDUFA date is the target date for the FDA to complete its review of Fampridine-SR.
Fampridine-SR is a sustained-release tablet formulation of the investigational drug fampridine (4-aminopyridine or 4-AP). In laboratory studies, fampridine has been found to improve impulse conduction in nerve fibers in which the insulating layer, called myelin, has been damaged. Fampridine-SR is being developed by Acorda Therapeutics and manufactured by Elan Corporation plc.
Multiple sclerosis is a chronic, usually progressive disease in which the immune system attacks and degrades the function of nerve fibers in the brain and spinal cord. More than 400,000 Americans have MS, most between the ages of 20 and 50, with women affected two to three times more than men. Worldwide, MS may affect 2.5 million individuals.
Research indicates 64%-85% of people with MS have difficulty walking, and 70% report walking to be the most challenging aspect of their MS. Within 15 years of an MS diagnosis, 50 percent of patients often require assistance walking and, in later stages, up to a third of patients are unable to walk.
