North American Prodromal Synucleinopathy Consortium (NAPS)
April 6, 2022 updated by: Washington University School of Medicine
This study will enroll participants with idiopathic rapid eye movement (REM) sleep behavior disorder (RBD), for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.
Study Overview
Status
Enrolling by invitation
Detailed Description
REM sleep behavior disorder (RBD) is a rare disorder where people act out their dreams.
People with RBD often, but not always, develop Parkinson's Disease, dementia with Lewy bodies, multiple system atrophy, or other neurodegenerative diseases of the synucleinopathy type.
The North American Prodromal Synucleinopathy (NAPS) Consortium was formed with the purpose of enrolling participants with RBD, in anticipation of a future clinical trial of a neuroprotective treatment against synucleinopathies.
The NAPS Consortium will collect standardized clinical assessments, biofluids, and other data in order to develop biomarkers for synucleinopathies in the prodromal (presymptomatic) stage as well as a trial-ready registry of participants.
Participants procedures will include a ~2-hour clinical assessment (medical history and physical exam), questionnaires, blood draw, and (at select sites) optional lumbar puncture.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
YES
IPD Plan Description
This project will develop a large database of potential neurocognitive and polysomnographic biomarkers in rapid eye movement sleep behavior disorder (RBD), as well as a biobank of blood, DNA, and cerebrospinal fluid from individuals with RBD.
Since individuals with RBD frequently develop synucleinopathies including Parkinson Disease, Dementia with Lewy Bodies (DLB), and Multiple System Atrophy, we anticipate that the data and samples we collect will be valuable for investigators interested in synucleinopathies, other dementias such as Alzheimer's Disease (AD), and sleep disorders.
The neurocognitive battery will contain all components of the Uniform Dataset version 3 (UDS 3) with the additional DLB module, to harmonize with research efforts in AD and DLB.
Biofluid samples will be banked at the National Cell Repository for Alzheimer's Disease (NCRAD) to facilitate distribution to other investigators.
IPD Sharing Time Frame
Data will be made available after primary analyses planned by NAPS investigators in 2020.
Data will be available indefinitely.
IPD Sharing Access Criteria
IPD and sample requests will be determined by a Steering Committee
