A Prospective Registry for Patients with REM Sleep Behavior Disorder and Polysomnographic REM Sleep without Atonia and Controls
Rochester, MN
The purpose of this study is to follow patients with REM sleep behavior disorder (RBD) over time and learn which types of RBD patients may be at risk of developing other diseases.

Efficacy of Extended Melatonin on sleep cycle in patients with PD and RBD.
Jacksonville, FL
The primary aim of this study is to compare effectiveness of immediate versus extended-release melatonin as a supplement affecting the sleep cycle among patients with Parkinson’s disease as assessed by modified Mayo Sleep Questionnaire (MSQ). The secondary aim is to evaluate the superiority and effect of immediate and extended-release melatonin versus not taking any melatonin on sleep cycle among patients with Parkinson’s disease as assessed by modified Mayo Sleep Questionnaire (MSQ).
Rapid eye movement (REM) sleep behavior disorder (RBD) is very common in patients with Parkinson disease and manifests with the loss of REM sleep atony, vigorous motor jerks, nocturnal vocalizations ...

Study Evaluating Nelotanserin for Treatment of REM Sleep Behavior Disorder in Subjects With Dementia (DLB or PDD)
Rochester, MN
This study seeks to evaluate the safety and efficacy of Nelotanserin for the treatment of Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) in subjects with dementia with Lewy bodies (DLB) or Parkinson's disease dementia (PDD).

Submandibular Gland Needle Core Biopsy and Skin Punch Biopsy as Tissue Biomarkers for the Diagnosis and Monitoring of Disease Progression of Parkinson’s Disease and REM Sleep Behavior Disorder
Scottsdale/Phoenix, AZ
Determine 1) the magnitude of SMG and skin a-syn density change over time, 2) the
improvement in adequate tissue acquisition doing bilateral SMG biopsies, 3) any laterality differences between
SMG gland a-syn density, 4) correlate a-syn density and changes in density between SMG and skin biopsies
Specific Aim 1. Determine, with bilateral submandibular gland (SMG) biopsies in 30 clinically
diagnosed subjects with Parkinson’s disease (PD) and 20 clinically probable REM sleep behavior
disorder (RBD) subjects whether bilateral biopsies improve the rate of acquisition of adequate
glandular tissue, whether alpha-synuclein (a-syn) SMG pathology ...

Rochester, MN
This study seeks to evaluate the long-term safety and effectiveness of nelotanserin for the treatment of visual hallucinations (VHs) and Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) in subjects with Lewy body dementia (LBD).

North American Prodromal Synucleinopathy (NAPS) Consortium
Rochester, MN
The purpose of this study is to establish a registry of RBD patients, develop quantitative biological and functional measures of synucleinopathy burden, and establish a formal process to evaluate candidate neuroprotective agents.

Synucleinopathies
Rochester, MN
The goals of the study are to prospectively evaluate clinical and laboratory biomarkers of multiple system atrophy and Parkinson’s disease at early clinical disease, at a premotor stage (PAF), and even at a prodromal stage (RBD).

North American Prodromal Synucleinopathy Consortium for RBD
Rochester, MN
Most individuals with rapid eye movement (REM) sleep behavior disorder (RBD) develop additional
neurological symptoms and are subsequently diagnosed with overt synucleinopathies, including dementia with
Lewy bodies (DLB), Parkinson disease (PD), and multiple system atrophy (MSA), indicating that RBD
represents a prodromal stage of synucleinopathy. RBD therefore offers a window of opportunity to intervene
with neuroprotective treatments at the earliest stages of disease when treatment is most likely to be effective.
Recognizing the importance of early intervention, key federal agencies focused on neurodegenerative disease
have proposed high priority recommendations for prodromal aspects of synucleinopathies, including
specifically RBD, to prepare for ...
