NCT01141023

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.

Outcome Measures

Primary Outcomes (1)

  • Mean Rates of Change

    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.

    Baseline to 156 months

Secondary Outcomes (5)

  • Comparison between Rates of Change

    Study intervals ranging from 3 months to 156 months

  • Prevalence of measures of clinical, imaging and biomic outcomes in various subsets (

    study intervals ranging from baseline to 156 months.

  • Predictive Value

    Baseline to 156 months

  • To examine the proportion of SWEDD subjects that have a change in their clinical management at 24 months

    Baseline to 156 Months

  • Exploratory Analysis

    Baseline to 156 months

Study Arms (1)

Datscan SPECT Imaging

EXPERIMENTAL

Subjects will b injected with 3-5 mCi of dopamine transporter. Within a 4 hour (+/- 30 minutes) window following the injection, subjects will undergo SPECT imaging on the camera.

Drug: DaTscan

You may qualify if:

  • Parkinson Disease (PD) Subjects:

  • Has taken levodopa, dopamine agonists, MAO-B inhibitors or amantadine within 60 days of Baseline.
  • Has taken levodopa or dopamine agonists prior to Baseline for more than a total of 60 days.
  • Received any of the following drugs that might interfere with DAT imaging: Neuroleptics, metoclopramide, alpha methyldopa, methylphenidate, reserpine, or amphetamine derivative, within 6 months of Screening.
  • Current treatment with anticoagulants (e.g., coumadin, heparin) that might preclude safe completion of the lumbar puncture.
  • If applicable, currently taking medications that are known to cause QT-prolongation, or are currently taking tetrabenazine (TBZ or amphetamine type medications.
  • Condition that precludes the safe performance of routine lumbar puncture, such as prohibitive lumbar spinal disease, bleeding diathesis, or clinically significant coagulopathy or thrombocytopenia.
  • Healthy Control (HC) Subjects:
  • Current or active neurological disorder.
  • First degree relative with idiopathic PD (parent, sibling, child).
  • MoCA score \< 26.
  • Received any of the following drugs that might interfere with DAT imaging: Neuroleptics, metoclopramide, alpha methyldopa, methylphenidate, reserpine, or amphetamine derivative, within 6 months of Screening.
  • If applicable, currently taking medications that are known to cause QT-prolongation, or are currently taking tetrabenazine (TBZ) or amphetamine type medications.
  • Current treatment with anticoagulants (e.g., coumadin, heparin) that might preclude safe completion of the lumbar puncture.
