NCT03487367

Brief Summary

The investigators plan to fill the gap between the current state of clinical trial readiness and the optimal one for SCA1 and SCA3, which are fatal rare diseases with no treatments. Through US-European collaborations, the investigators will establish the world's largest cohorts of subjects at the earliest disease stages, who will benefit most from treatments, validate an ability to detect disease onset and early progression by imaging markers, even prior to ataxia onset, and identify clinical trial designs that will generate the most conclusive results on treatment efficacy with small populations of patients.

Outcome Measures

Primary Outcomes (13)

  • Change in disease progression in SCA1 and SCA3 as determined by change in scale for the assessment and rating of ataxia (SARA) score over time.

    Scale for the assessment and rating of ataxia (SARA) was evaluated in two large validation trials performed by the EUROSCA clinical group and was found to be easy to use, reliable and valid. SARA has eight categories with accumulative score ranging from 0 (no ataxia) to 40 (most severe ataxia).

    Every 12 months for approximately 60 months

  • Change in disease progression in SCA1 and SCA3 as determined by change in Composite Cerebellar Functional Severity Score (CCFS) total score over time.

    Composite Cerebellar Functional Severity Score (CCFS) is a validated quantitative scale used to evaluate cerebellar ataxia in adults and children. Total score calculation includes both the 9-hole pegboard test and the click test. A higher score indicates more severe cerebellar impairment.

    Every 12 months for approximately 60 months

  • Change in disease progression in SCA1 and SCA3 as determined by change in timed 25 foot walk test (T25FW) over time.

    Timed 25 foot walk test (T25FW) is a quantitative mobility and leg function performance test based on a timed 25-walk. The T25FW has high inter-rater and test-retest reliability and shows evidence of good concurrent validity. Gait speed in general has been demonstrated to be a useful and reliable functional measure of walking ability.

    Every 12 months for approximately 60 months

  • Change in disease progression in SCA1 and SCA3 as determined by change in Cerebellar Cognitive Affective Syndrome (CCAS) score over time.

    Cerebellar Cognitive Affective Syndrome Scale (CCAS Scale) is a battery of cognitive tasks used for determining the role of the cerebellum in the regulation of cognitive functions and present the procedure of neuropsychological diagnosis useful in indicating the specific cognitive and emotional problems in patients with cerebellar damage.

    Every 12 months for approximately 60 months

  • Change in disease progression in SCA1 and SCA3 as determined by change in Inventory of Non-ataxia Symptoms (INAS) total count over time.

    Inventory of Non-ataxia Symptoms (INAS) is a scale utilized in recording the occurrence of accompanying non-ataxia symptoms. In the SARA validation trials, INAS was applied to a large number of SCA patients. Statistical evaluation showed good reliability.

    Every 12 months for approximately 60 months

  • Change in disease progression in SCA1 and SCA3 as determined by change in Functional staging score over time.

    Functional staging is an instrument used to assess ambulatory capabilities of patients with cerebellar symptoms.

    Every 12 months for approximately 60 months

  • Change in level of disease activity based on change in cerebellar and brainstem volumes since baseline imaging. (Aim 2)

    Change in level of disease activity based on change in cerebellar and brainstem volumes since baseline imaging.

    Every 12 months for approximately 36 months

  • Change in level of disease activity based on grey matter (GM) and white matter (WM) loss metrics from voxel-based morphometric (VBM) since baseline imaging. (Aim 2)

    Change in level of disease activity as defined by change in grey matter volume and white matter volume from voxel-based morphometric data since baseline imaging.

    Every 12 months for approximately 36 months

  • Change in level of disease activity based on change in metabolite concentrations since baseline imaging. (Aim 2)

    Change in level of disease activity on MR morphological, biochemical (MRS) and functional (resting-state fMRI) as defined by change in metabolite concentrations since baseline imaging.

    Every 12 months for approximately 36 months

  • Change in level of disease activity based on change in fractional isotropy since baseline imaging. (Aim 2)

    Change in level of disease activity on MR morphological, biochemical (MRS) and functional (resting-state fMRI) as defined by change in mean diffusivity since baseline imaging.

    Every 12 months for approximately 36 months

  • Change in level of disease activity based on change in mean diffusivity since baseline imaging. (Aim 2)

    Change in level of disease activity on MR morphological, biochemical (MRS) and functional (resting-state fMRI) as defined by change in mean diffusivity since baseline imaging.

    Every 12 months for approximately 36 months

  • Change in level of disease activity based on change in radial and axial diffusivity since baseline imaging. (Aim 2)

    Change in level of disease activity on MR morphological, biochemical (MRS) and functional (resting-state fMRI) as defined by change in radial and axial diffusivity since baseline imaging.

    Every 12 months for approximately 36 months

  • Change in level of disease activity based on change in degree of co-activation within resting state networks since baseline imaging. (Aim 2)

    Change in level of disease activity on MR morphological, biochemical (MRS) and functional (resting-state fMRI) as defined by change in degree of co-activation within resting state network since baseline imaging.

    Every 12 months for approximately 36 months

    Every 12 months for approximately 60 months

  • +1 more secondary outcomes
