NCT03418740

Brief Summary

The purpose of this study is to identify ways to follow progression of Friedreich's Ataxia (FA) and be able to measure changes over time in children with FA. Participants will have biannual visits to observe how the disease progresses over time and determine the rate of progression.

Outcome Measures

Primary Outcomes (1)

  • Change in mFARS (Modified Friedreich's Ataxia Rating Scale) Score

    The Friedreich Ataxia Rating Scale (FARS) measures neurological function in FA. It is a composite measure reflecting neural substrates with five-subscales (sections A to E), measuring bulbar function, upper limb coordination, lower limb coordination, peripheral nerves, and upright stability. The modified FARS (mFARS) shortens the bulbar subscale to 2 items and excludes the peripheral nerve subscale. Total scoring is a summation of subscales, with a maximum score of 93 points for mFARS and 125 for FARS. The mFARS score ranges for each subscale are: Bulbar: 0 - 5, Upper Limb: 0 - 36, Lower Limb: 0 - 16, Upright Stability: 0 - 36. The overall change in mFARS and its sub scores across 3 years was the outcome measure analyzed at 0, 1, 2, and 3 year visits. Each subsection has a minimum score of 0, indicating minimal effect for that component. Maximum values per section vary based on the tasks performed in each subsection; a higher score indicates greater dysfunction on that component.

    Baseline up to 36 Months

Secondary Outcomes (6)

  • Change in Timed 25-Foot Walk (T25FW) Test

    Baseline up to 36 Months

  • Change in 9-Hole Peg Test (9HPT)

  • Change in Timed Up and Go (TUG) Test

    Baseline up to 36 Months

  • Change in Berg Balance Scale (Full Length) (BBS) Score

  • Change in FA-Activities of Daily Living Scale (ADL) Score

Sampling MethodProbability Sample
Study Population

This study will primarily take place at the Children's Hospital of Philadelphia (CHOP), with a select number of subjects only participating in the clinical testing at the University of Florida and University of California Los Angeles (UCLA). The investigators expect to recruit approximately 100 children across all three sites and study each of them over a 3 year period. Children with a genetically or clinically confirmed diagnosis of Friedreich's Ataxia (FA) will be offered participation.

You may qualify if:

  • Males or females age 2 to 18 years.
  • Genetically confirmed diagnosis of Friedreich's Ataxia (FA) or clinically confirmed diagnosis of FA, pending confirmatory genetic testing through a commercial or research laboratory
  • Parental/guardian permission (informed consent) and if appropriate, child assent.

You may not qualify if:

  • \) Inability to complete study evaluations

Limitations and Caveats

Potential training effects of the repeated outcome measures as well as placebo effects might have increased variability. Varying demographic and genetic factors such as the presence of point mutations, GAA1 repeat length, age of onset and age at baseline also contribute to variability and may impact the rates of change over time. The COVID-19 epidemic also contributed to intermittent loss of data, and supplementing with virtual visits had limited value.
