Fampridine-SR ("4-aminopyridine", "4-AP", “fampridine”) is an investigational oral, sustained-release formulation of 4-aminopyridine. In laboratory studies fampridine has been found to improve impulse conduction in nerve fibers in which the insulating layer, called myelin, has been damaged.

Clinical History of Fampridine-SR in SCI

In 2004, Acorda completed two Phase 3 clinical trials of Fampridine-SR in people with spinal cord injury (SCI). These studies did not reach statistical significance in their primary endpoints, reduction of spasticity (as measured by the Ashworth score) and improvement of participant's Subject Global Impression (SGI) rating.

Acorda recently completed a Phase 3 clinical study of Fampridine-SR in people with all types of MS. For a copy of the press release and study results, please click here.
