FoxBioNet: ECV (Extracellular Vesicle) 003

The goal of this study is to optimize pre-analytical cerebrospinal fluid (CSF) extracellular vesicle isolation protocols for increasing the detection of LRRK2 activity in human CSF

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Specific aims to accomplish this objective are:

PRIMARY OBJECTIVES:

  • To evaluate a series of extracellular vesicle isolation methods for their ability to enrich for LRRK2 and increase the detection of LRRK2 in CSF samples.
  • To compare the measurements of LRRK2, p1292 LRRK2, Rabs and pRabs from the ECVs isolated using each method.
  • To assess the inter-lab reliability of each method

SECONDARY OBJECTIVES

  • To assess the ability of the network of sites to efficiently conduct a study involving biosample collection for PD research. Efficiency will be assessed using measures of the time taken to meet specific milestones within the study
  • To assess the ability of the network to collect high quality biospecimens adhering to agreed-upon protocols.
  • To gauge the willingness of participants to participate in subsequent Fox BioNet studies

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

Approximately 36 subjects will be enrolled to participate in this study, a combination of Parkinson Disease (PD) (any stage) and Healthy Controls in no specified proportion.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
degree of LRRK2 enrichment achieved. The measure will vary depending on the method of LRRK2 enrichment used
Time Frame: 1 year
For methods involving immunoprecipitation: Increase in peptide spectral matches on mass spectrometry For methods amenable to antibody-based detection: increase in LRRK2 intensity on Western blotting (arbitrary units).
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
