Statement from the Parkinson’s Foundation

Our thoughts are with the family members who lost a loved one enrolled in this trial. Their participation in clinical research will ultimately help make life better for the people diagnosed with Parkinson's in the future. 

The Parkinson’s Foundation remains confident that Acorda and the FDA will investigate this rare event. Clinical trials in Parkinson’s disease — from oral therapies to surgical treatments — have had a strong safety record and they are critical in testing the safety and efficacy of investigational therapies.

In order to discover new PD therapies, we rely on brave and altruistic people, like the ones in this trial, to participate in clinical research. The Parkinson’s Foundation remains committed to supporting clinical research through our global network of Centers of Excellence and Parkinson’s Advocates in Research.
