Friedreich's ataxia

Data Standards

The National Institute of Neurological Disorders and Stroke (NINDS) and other Federal agencies and international organizations have the common mission of developing data standards for clinical research. Through the efforts of subject-specific working groups, topic-driven data elements have been created. The first set of Common Data Elements (CDEs) for Friedreich’s ataxia (FA) was developed in 2011. The Core data elements to be used by an investigator when beginning a research study in this disease/disorder are listed in the Start-up Resource Listing.

Many of the CDEs will overlap across study types, which allows for comparisons and meta-analysis across studies. Consistency of the data elements and the CDE formats is kept in order to ensure the ability to transfer critical medical information electronically from one center to another. This consistency also allows for continuity across different disease areas. The goals of the NINDS CDE initiative are to increase the efficiency and effectiveness of clinical research studies and clinical treatment, increase data quality, facilitate data sharing, and help educate new clinical investigators.

Organized by domains and sub-domains, often used in clinical studies, data standards include:

An overview of all FA CDE recommendations can be found in the FA CDE Highlight Summary document. For your reference, a zip file containing all the current FA CRF modules can be downloaded below.

The outline that follows includes all the CDEs associated with the CRF modules, organized by domain and sub-domain.

Prospective Assessments for Suicidal Ideation and Behavior

Investigators should review the FDA’s "Guidance for Industry: Suicidal Ideation and Behavior: Prospective Assessment of Occurrence in Clinical Trials” for the most up-to-date information about suicidal ideation and behavior. One scale that FDA suggests is the Columbia Suicide Severity Rating Scale (C-SSRS) (available at http://www.cssrs.columbia.edu).

Overview

To develop the Friedreich’s ataxia (FA) CDEs, the FA CDE Working Group divided into subgroups to focus on identifying and defining data elements in the domains of:

  • Ataxia and Performance Measures
  • Biomarkers
  • Cardiac and Clinical Outcomes
  • Demographics, Medical History/ Prior Health Status, Laboratory Tests/ Vital Signs

Data standards include CDEs as well as case report form (CRF) Modules and Guidelines. The CRF Modules logically organize the CDEs for data collection, while the Guidelines provide further information about the CDEs. The CDEs, CRF Modules, and Guidelines presented are organized into domains which are intuitive and common in clinical research studies.

Roster

The National Institute of Neurological Disorders and Stroke (NINDS) has formed an Oversight Committee to direct the updating and further development of Friedreich’s ataxia CDEs. The Friedreich’s ataxia CDE Committee is supported by the NINDS CDE Team.

Previously, the Friedreich’s ataxia CDE Committee was comprised of four different subgroups. Chairs were appointed to lead the overall Working Group and the individual subgroups. The Working Group members actively developed the CDEs for their specific subgroups and also had an opportunity to review and comment on the recommendations of the other subgroups.

The Working Group members served on either one or two subgroups. The subgroups began meeting by teleconference in August 2010 and continued to hold calls every four to six weeks through early 2011 to define the CDEs for their domains and to recommend standardized, validated instruments for Friedreich’s ataxia research. The Friedreich’s ataxia CDE Oversight Committee was created in 2013.
