About this study

The goal of this study is to identify reliable markers of LRRK2 activity in human CSF.

Read the detailed description

Specific aims of this project are:

Primary Objectives:

To evaluate each assay performance for its ability to detect LRRK2, its activity and/or the detection and activity of the pathways it impacts using a variety of different approaches (quantitative western blot, immunoassays and LC-MS). Assay performance will be assessed and those demonstrating high sensitivity and consistency will be considered for further development.

Secondary Objectives:

To assess the ability of the assay or a combination of assays to differentiate pathogenic LRRK2 variant manifesting and non-manifesting carriers, idiopathic PD and healthy non-carriers.

Questions about this trial

What is this clinical trial studying?

An observational study of Parkinson Disease, run by Michael J. Fox Foundation for Parkinson's Research at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 40 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assay Evaluation (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2023.
