A clinical trial is a research study in human volunteers designed to answer specific questions about the safety and/or efficacy of an experimental drug. Carefully conducted clinical trials are the safest and most effective way to find new treatments that improve people’s health.

For more information about clinical trials, you may refer to the NIH’s overview of the clinical process, available at www.clinicaltrials.gov.

Acorda currently has one product candidate in clinical development:

• Fampridine-SR for multiple sclerosis (MS)

Acorda’s clinical trials are designed to evaluate the safety and efficacy of potential treatments in order to bring new therapies to these markets, in which there are substantial unmet medical needs. Acorda recently completed a Phase 3 clinical study of Fampridine-SR to evaluate its safety and efficacy in improving walking ability in people with all types of MS.
