Friedreich Ataxia Global Clinical Consortium UNIFIED Natural History Study

This project is a global, multicenter, prospective, longitudinal, observational natural history study that can be used to understand the disease progression and support the development of safe and effective drugs and biological products for Friedreich ataxia.

The UNIFAI Study: Friedreich Ataxia Global Clinical Consortium UNIFIED Natural History Study is a global research study designed to provide a deep and evolving understanding of the natural history of this rare and debilitating genetic disorder as well as inform clinical trial design and implementation. Friedreich's Ataxia is a rare, inherited, multi-system condition characterized by progressive neurological and cardiac symptoms. It is caused by mutations in the FXN (frataxin) gene. The UNIFAI study is a multicenter, prospective, longitudinal, observational study, which means that all data about the natural disease course will be captured at study visits conducted annually according to a single protocol for all sites. This study will recruit participants with FA worldwide, to be assessed annually for up to 25 years. Study participation involves yearly study visits with data collected from medical records and history along with clinical outcome assessments including, neurological exams, timed walking tests, upper limb function measures, and patient-reported quality of life assessments, with the option for sites to collect additional ancillary measures related to speech, vision, fatigue, balance and cognition. This global study is a harmonization of two well-established, long-standing natural history studies in FA that have provided a framework for further investigation of clinical measures that can quantitatively assess FA: FACOMS (US, Canada, Australia, New Zealand, and India) and EFACTS (European countries). These studies have been conducted in parallel with many similarities in study conduct. Uniting these two existing studies and groups of researchers gives greater power to data previously collected as well as future data. It also continues efforts to expand the network of clinical research centers specializing in FA called the FA-Global Clinical Consortium. Due to advances in understanding the genetic and cellular dysfunction of FA that lead to symptoms observed in affected individuals, there has been significant growth in the discovery and development of therapeutic approaches, many currently being evaluated in clinical trials and a first approved treatment in the United States in 2023. The UNIFAI study aims to build upon this momentum by focusing on several key objectives. UNIFAI will assess the natural history of FA by collecting data from diagnosed individuals of all ages and stages of disease progression. The data collected includes demographics, medical history, medications, neurological and functional assessments, cardiac examinations, laboratory studies, and health questionnaires. The study will assess and evaluate clinical outcomes in individuals with FA, such as disease progression, symptom severity, and overall quality of life, by various factors that might influence such outcomes such as genetic mutation, demographics (age, geography), co-existing conditions, medications, or treatments. By tracking outcomes over time, research trial.show_full_description
