Our Mission

The mission of PPMI is to identify one or more biomarkers of Parkinson’s disease progression. The discovery of a biomarker is a critical step in the development of new and better treatments for PD. This study is being sponsored by The Michael J. Fox Foundation for Parkinson's Research.

A Landmark Study of Parkinson’s Disease

PPMI is a landmark observational study to better define and measure Parkinson’s disease to speed therapeutic development. PPMI makes its data set and biorepository — the most robust in Parkinson’s to date — available to academia and industry to accelerate breakthroughs.

Launched in 2010, PPMI has gathered longitudinal data from more than 1,400 individuals at 33 clinical sites in 11 countries. The study is now recruiting a larger and more diverse group of individuals — de novo Parkinson’s, control volunteers and at-risk populations — who can contribute to a more detailed look into the way the disease develops and changes over time. PPMI will grow to 50+ sites and follow more than 4,000 participants.

PPMI is sponsored by The Michael J. Fox Foundation for Parkinson’s Research and supported by various industry, non-profit and private partners.
