Clinical Trial Summary

This study evaluates cognitive impairment in subjects with Parkinson disease (PD) and similar neurological disorder through obtaining longitudinal clinical and neuropsychological data. The long term goal is to have a well-characterized subject population to contribute to our understanding of the natural history, diagnosis and ultimate treatment of cognitive impairment in patients with PD and similar disorders.

Clinical Trial Description

The Pacific Northwest Udall Center (PANUC) Clinical Core has recruited and characterized a cohort of more than 600 individuals with Parkinson's disease (PD) during the initial funding period. Data from the PANUC Clinical Core, in collaboration with other Udall Centers and other academic medical centers, have helped confirm apolipoprotein E (APOE) (1) and glucocerebrosidase (glucosidase, beta, acid or GBA) (2)as genes that increase the risk and modify the phenotype (1) of cognitive decline in PD. Understanding the mechanisms underlying these gene effects is the focus of this renewal application, and the Clinical Core will provide well-characterized PD and control subjects of appropriate genotypes for PANUC projects. In addition, the majority of the existing cohort will be retained for additional longitudinal clinical and neuropsychological testing follow-up to support ongoing genetic and biomarker studies, with a refined battery of tests and a uniform biannual frequency of visits designed to maximize efficiency. Balance and gait testing (already piloted at the Portland site) will be added to the test battery for the entire cohort as an innovation that is thought to reflect higher order CNS function closely related to cognition. This innovation leverages the expertise of Dr. Horak, an investigator introduced to the PANUC by way of PANUC Pilot Award funding during the last funding period. As in the current cycle, Clinical Core subjects will be followed in identical fashion at two sites: one at UW directed by Dr. Hu, and the other at OHSU directed by Core Leader Dr. Quinn. Project 3 leader Dr. Horak will oversee balance and gait testing at OHSU and Dr. Kelly will oversee balance and gait testing at UW. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
