NCT06016946

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Change in modified Friedreich Ataxia Rating Scale (mFARS) Score

    The modified Friedreich Ataxia Rating Scale (mFARS) is a disease-specific scale that measures progression of neurological effects of FA. The mFARS is a validated and reliable scale; comprised of the neurologic component of the FARS and evaluates bulbar, upper limb, lower limb, and upright stability/gait function. For each item, responses categorize the corresponding neurological finding, and the findings are assigned a score ranging from 0 to 3, 4, or 5 with 0 being normal and higher numbers indicative of greater impairment. The score ranges from 0 to 93. The score will be compared to the previous year annually for up to 25 years.

    Baseline, Year 1-25

  • Change in Scale for the Assessment and Rating of Ataxia (SARA) Score

    The Scale for the Assessment and Rating of Ataxia (SARA) is a semi-quantitative assessment of ataxia, measuring ataxia of upper limb, lower limb, gait, balance and speech. It has eight items: gait, stance, sitting, speech disturbance, finger chase, nose-finger test, fast alternating hand movement, and heel-shin slide. The total score ranges from 0 (no ataxia) to 40 (severe ataxia). The score will be compared to the previous year annually for up to 25 years.

    Baseline, Year 1-25

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

    The FARS-ADL is a subsection of the FARS questionnaire that assesses activities of daily living, including speech, personal hygiene, feeding, and mobility. Participants rank each category using a scale of 0 (normal) to 4 (severe disability/ inability to carry out activity independently), with lower scores indicative of "normal" function/activity. The score will be compared to the previous year annually for up to 25 years.

    Baseline, Year 1-25

  • Change in Upright Stability (US) Score

    The Upright Stability (US) assessment is part of the neurological examination within the Modified Friedreich Ataxia Rating Scale (mFARS). This component comprises nine items: sitting position, stance with feet apart, stance with feet apart and eyes closed, stance with feet together, stance with feet together and eyes closed, tandem stance, stance with dominant foot, tandem walk, and gait. The score ranges from 0 to 9, with a higher score reflecting poorer upright stability (i.e., greater neurological severity). The score will be compared to the previous year annually for up to 25 years.

    Baseline, Year 1-25

Secondary Outcomes (5)

  • Change in 9-hole peg test mean time (seconds)

    Baseline, Year 1-25

  • Change in Timed walk (25-foot or 8-meter) mean time (seconds)

    Baseline, Year 1-25

  • Change in Speech analysis scores

    Baseline, Year 1-25

  • Change in Ataxia Instrumented Measures (AIMs)clinical severity score

    Baseline, Year 1-25

  • Change in Lower Contrast Letter Acuity test score

    Baseline, Year 1-25

  • Individuals with Friedreich ataxia (FA): Participants that meet genetically confirmed diagnosis of Friedreich ataxia
  • Written informed consent provided
  • Informed consent must be obtained for all participants
  • For underage participants, they and the parent/ legally authorized representative have to sign the informed consent form, child assent (if applicable)
  • Persons who are not legally competent require the informed consent of their legally authorized representative

You may not qualify if:

  • Unable or unwilling to provide informed consent
  • Acute or ongoing medical or other conditions that would interfere with the conduct and assessments of the study
  • For any reason in the opinion of the investigator, participant would be unlikely or unable to comply with study protocol requirements.
