The Personalized Parkinson Project: Examining Disease Progression Through Broad Biomarkers in Early Parkinson's Disease

Initiatives -
The primary objective of the study is to perform a set of hypothesis-driven analyses on the study data set, aiming to correlate established biomarkers (obtained clinically, from brain MRI, from CSF, from known genetic factors, and from monitoring of biosensors signals) to the rate of disease progression, and to responses to treatment (both pharmacological and behavioural, such as participation in exercise). The secondary objective of the study is to evaluate the Verily Study Watch, to assess how this device could provide information about the function of patients with Parkinson’s disease. Additionally, this cohort will serve as a source of data that can be accessed by qualified researchers worldwide. Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.
Start Year
The study is financially supported by Verily Life Sciences LLC, Radbouduniversity medical center, Radboud University, the city of Nijmegen and theProvince of Gelderland. The collaboration project is co-funded by the PPP Al-lowance made available by Health~Holland, Top Sector Life Sciences & Health,to stimulate public-private partnerships. The co-authors employed by Verily LifeSciences LCC (BRB, RK and TMS) were involved in the design of the study andpreparation of the manuscript. The other study sponsors had no role in studydesign and collection, analysis and interpretation of data or in writing the manuscript.
