The PPMI study was designed with the flexibility to incorporate new biomarker assessments throughout the life of the project. Ancillary studies include additional study assessments that involve all or a subset of PPMI participants.
Submit an Ancillary Study
Investigators interested in proposing an ancillary study to PPMI can submit an ancillary study. Ancillary study submissions are reviewed on an ongoing basis by the PPMI Ancillary Study Committee, chaired by Caroline Tanner, M.D., Ph.D.
