Overview of

Active PD Clinical Trials Worldwide

About PDTrialTracker.info


Parkinson's disease (PD) is a progressive neurological disorder affecting an estimated 1 million people in the United States and 7 to 10 million people worldwide.  


PDTrialTracker.info provides Parkinson's patients, families, researchers, health care providers, and other interested members of the PD community with analysis of ongoing PD clinical trials and observational studies throughout the world in order to help:

  • understand the types of trials underway and where they are in the pipeline,
  • highlight promising avenues of research 
  • uncover roadblocks in the trial process and ways to address them,
  • promote accurate and timely sharing of trial information for ongoing and completed trials
  • facilitate greater collaboration between patients, researchers, and physicians to accelerate progress towards a cure.


PDTrialTracker.info captures trial data from ClinicalTrials.gov, the largest database of privately and publicly funded clinical studies conducted around the world on a wide range of diseases.  Launched in February 2000, ClinicalTrials.gov is maintained by the National Library of Medicine at the National Institutes of Health (NIH).  Trial data on ClinicalTrials.gov is submitted directly by each study's sponsor or principal investigator.  To date, over 3900 Parkinson's disease trials have been listed on ClinicalTrials.gov, with about 1000 of these currently active. ​

Note:  Active PD trials are either i) currently recruiting, ii) not yet recruiting, iii) enrolling by invitation or iv) in-progress, not recruiting.
