French Parkinson's Disease Cohort - NS-PARK (NS-PARK)

Cohort of the French Clinical Research Network for Parkinson's Disease (NS-PARK Cohort)

The aim of NS-PARK cohort are to describe the natural history of Parkinson's disease (PD), and to propose patients stratification models based on PD pathophysiological mechanisms. Patients are included at all PD expert centers in France. Standardized demographic, diagnosis, motor and non-motor symptoms evaluation, and treatment information are collected, and clinical data are updated at each visit of the patient at the center. A blood sampling is perform at baseline for genetic testing and implement an associated biocollection.

Descrição detalhada

The national clinical research network for Parkinson's disease (NS-PARK/FCRIN) reassembles all expert centers in Parkinson's disease (PD) in France. Its aim is to promote clinical research in Parkinson's disease and movement disorder, to better understand the pathophysiology of PD, foster the development of new therapeutic strategies, and move towards personalized medicine. To help centers for prescreening, a national registry of PD patients followed in each centers has been implemented in 2016 to collect minimal relevant clinical information of patients followed in each center including demographic data, age at diagnosis, standardized motor and non-motor symptoms evaluation, and treatment. Data are updated at each visit of the patient in the center. De facto, this registry became a longitudinal cohort of PD patients followed in NS-PARK centers. In 2020, NS-PARK received funding to associate a biocollection to this clinical cohort.

The aim of NS-PARK cohort are to describe the natural history of PD progression in clinical routine in France, to develop new models of PD describing the different progression profiles, and to propose patients stratification based on PD pathophysiological mechanisms. The cohort will also serve as a platform to discover new PD genes and genetic modifiers of disease progression or response to treatment.

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Predictive factorsof PD progression: motor or non motor symptoms
Prazo: through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Motor or non motor symptoms as measured by MDS-UPDRS scores will be used as predictive factors for primary outcomes
through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Predictive factors of PD progression: genetic variants
Prazo: through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Genetic variants in PD genes or the Genetic PD risk score will be used as predictive factors for primary outcomes.
through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Predictive factors of PD progression: brain imaging markers
Prazo: through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Brain imaging makers (iron or neuromelanine content of the substantia nigra) will be used as predictive factors for primary outcomes
through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Clusters of patients with similar disease progression profiles
Prazo: through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Clustering analyses will be performed on disease progression markers (Hoehn and Yahr score, MDS-UPDRS scores, and doses of treatment (levodopa equivalent daily doses)) to identify homogeneous groups of patients (clusters) sharing similar disease progression profiles.
through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Clusters of patients with similar genetic and disease progression profiles
Prazo: through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Co-clustering analysis of disease progression markers (Hoehn and Yahr score, MDS-UPDRS scores, and doses of treatment (levodopa equivalent daily doses)) and genetic markers (variants in PD genes or the Genetic PD risk score).
through the end of follow-up in the cohort, at least 2 years, and average of 5 years
Genetic mutations associated with familal forms of PD
Prazo: through study completion, 15 years
Genetic mutations will be screened by different methods (gene panels, whole exome or whole genome) in familial forms of PD. Mutations co-segregated with PD will be considered as potentially associated with the disease.
through study completion, 15 years
