Current Primary Outcome Measures (submitted: August 12, 2019)

Mean Rates of Change [ Time Frame: Baseline to 156 months ]

The mean rates of change and the variability around the mean of clinical, imaging and biomic outcomes in early PD patients, and where appropriate the comparison of these rates between PD patient subsets and between various subsets (including, but not limited to: PD vs. healthy subjects, PD vs. SWEDD, PD vs. prodromal, PD with and without LRRK2, GBA or SNCA mutation, unaffected LRRK2, GBA or SNCA mutation carriers vs. healthy controls) at study intervals ranging from 3 months to 36 months. Specific examples of outcomes include MDS-UPDRS, dopamine transporter imaging striatal uptake, vesicular monoamine transporter type-2 uptake, and serum and CSF alpha-synuclein. PD patient subsets may be defined by baseline assessments, genetic mutations, progression milestones and/or rate of clinical, imaging, or biomic change.

Brief Summary

This is a observational, multi-center study to assess progression of clinical features, imaging and biologic biomarkers in Parkinson disease (PD) patients compared to healthy controls (HC) and in PD patient subtypes.

The primary objective of this study is to identify clinical, imaging and biologic markers of PD progression for use in clinical trials of disease-modifying therapies.

Detailed Description

Amendment 14 - 26-Mar-2018 Revised to reflect the implementation of PPMI Wearables and Sensor Study Companion Protocol

Amendment 13 - 20-Nov-2017 Extension of study duration until 2023 for all cohorts (except Genetic Registry).

Incorporation of Parkinson's Disease Risk Factor Questionnaire (PD-RFQ) into FOUND.

Amendment 11 - 01-Apr-2016 Added the collection of peripheral blood mononuclear cells (PBMC) from blood samples at interim visits.

Addition of PPMI Pathology Core/PPMI Brain and Tissue Bank Addition of Gait Assessment Companion Study (Select PPMI sites - Genetic Cohort only) Testing for additional GBA mutations - previously testing involved testing only for the GBA N370S mutation; however, going forward, testing will include tests for additional GBA mutations that are identified as being associated with certain ancestry.

More detailed description of new procedures including: Advance directive for clinical research participation; Extension of study period (for SWEDDs with positive scans at Yr. 2) by continuing or re-inviting to study and followed (as per PD subjects through Month 60); Objective Parkinson Disease Measurement (OPDM) finger tapping measurement.

Amendment 7 - 14-Oct-2013 Pre-Screening Prodromal - RBD clarifications Pre-Screening Genetic Cohort - clarified Assessments/tests clarified, including addition of consent (or withdrawal of consent, if applicable) for future contact about future studies and PD family history data collection for Genetic cohort subjects as selected visits.

Amendment 2 - 19-May-2011 Changed visit window from 30 days to 45 days for Baseline visit to be completed.

Section on DAT and SPECT Imaging - section changed to account for subject travel to the Institute for Neurodegenerative Disorders to conduct SPECT scanning and injection of either DaTSCAN or BCIT.

Main Protocol - PPMI will be a five-year natural history study (a minimum of 3-year involvement for each subject) of de novo idiopathic PD patients and healthy controls. This study will also include a SWEDD (subjects without evidence of dopaminergic deficit)and Prodromal populations.

All subjects will be comprehensively assessed at baseline and every three to six months thereafter. Subjects will undergo clinical (motor, neuropsychiatric and cognitive) and imaging assessments and will donate blood, urine, and cerebral spinal fluid (CSF). A blood sample for DNA will be collected. Data will be collected by each site under uniformly established protocols and data will be analyzed and stored at designated core facilities.
