Clinical Trial 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.


Description:

Spinocerebellar ataxia types 1 (SCA1) and 3 (SCA3) are rare, inherited neurodegenerative disorders that relentlessly progress to total disability and death. SCA1 is the fastest progressing SCA while SCA3 is the most common SCA in US and Europe. Expanded (CAG)n repeats encoding polyglutamines (polyQ) in the respective genes, Ataxin 1 (ATXN1) and Ataxin 3 (ATXN3), cause SCA1 and SCA3. Disease-modifying therapies that target the pathway upstream of the complex pathogenic cascade will offer ultimate treatment. Scientific premise and preclinical animal data strongly support MSK1 inhibitors for SCA1, citalopram for SCA3, and nucleotide-based gene silencing for both SCAs as drugs to be examined in clinical trials in five years. However, the challenge that investigators face in current clinical trial readiness for such disease-modifying therapies is that the modest effect size of candidate drugs as measured by the Scale for the Assessment and Rating of Ataxia (SARA; the most robust and well-validated clinical outcome assessment measure) requires large cohorts of study subjects to achieve sufficient statistical power. To accomplish the goal of establishing clinical trial readiness, the investigators propose to launch an international, multi-site effort focusing on premanifest mutation carriers and patients in an early disease stage, who are likely responders to the disease-modifying interventions prior to irreversible brain damage. Based on the investigators' studies funded by NIH and the National Ataxia Foundation (NAF), the US ataxia consortium has developed an unprecedented opportunity for tight collaborations with the European Ataxia Study Group to jointly address this challenge and establish clinical trial readiness for SCA1 and SCA3. To achieve this goal, the investigators propose the following specific aims: Aim 1. Establish the world's largest cohorts of premanifest/early SCA1 and SCA3 by combining cohorts, clinical outcome assessment data and biofluid samples (blood, cerebrospinal fluid) from US and Europe Aim 2. Validate MR morphological, biochemical and functional biomarkers in premanifest and early SCA1 and SCA3 Aim 3. Adapt recent developments on statistical design and analysis of small population trials to SCAs.

Outcome

Type Measure Description Time frame Safety issue
Primary 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
Primary 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
Primary 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
Primary 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
Primary 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.
