Trials by Year
Recruiting Parkinson's trials that began in 2025 are up 1273% versus 2020 (151 vs 11).
Part of this multi-year increase reflects more complete ClinicalTrials.gov registration over time, not just more research. Trial registration became standard and then required, so earlier years are undercounted.
