Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a natural history study prospectively investigating neuroimaging markers of disease progression in children and adults with Friedreich ataxia (FA). There will be three assessment periods (baseline, 12 and 24 months). The study will include approximately 200 individuals with FA and 100 matched controls recruited across the six international academic sites. Other assessments will include secondary clinical and cognitive markers, as well as exploratory blood markers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Friedreich ataxia (FA) is a multi-system progressive disorder with the most prevalent and prominent symptoms relating to dysfunction in the central and peripheral nervous system, including, loss of balance and coordination, frequent falls, loss of ambulation, dysarthria, dysphagia and loss of vision and hearing. Other symptoms include cardiomyopathy, diabetes, scoliosis and fatigue. Age of onset can vary but most often presents during childhood, ages 5-15 years.

There is currently no cure and no disease-modifying treatment. Drug candidates to potentially treat FA are under development; however, there is a lack of well- characterized neuroimaging biomarkers for testing their efficacy in clinical trials, hampering this process. Establishing disease-specific neuroimaging biomarkers to track disease progression requires high-quality longitudinal data from large cohorts of patients, compared to controls. In rare diseases, such as FA, this can only be achieved through multi-site collaboration.

The aim of TRACK-FA is to develop an FA neuroimaging dataset from brain and spinal cord that is suitable for assessing the potential value of neuroimaging biomarkers and providing a basis for instituting them in clinical trials. The dataset will comprise a range of neuroimaging measures to assess changes in spinal cord and brain regions that have previously shown to be compromised in individuals with FA. In addition to neuroimaging measures, TRACK-FA will also include clinical, cognitive data and biospecimen data. The TRACK-FA dataset will provide a unique opportunity for academic researchers in collaboration with industry partners to access the images, subsidiary data, and associated clinical data for community research.

This multi-centre study is a collaborative effort across six academic institutions, together with industry partners and the Friedreich's Ataxia Research Alliance USA (FARA).
