The EUROSCA Natural History Study (EUROSCA-NHS)

June 28, 2017 updated by: Ataxia Study Group
The key goals of EUROSCA-NHS is to determine and compare the rate of disease progression in SCA1, SCA2, SCA3 and SCA6 including determination of the order and occurrence of non-ataxia symptoms, assessment of activities of daily living (ADL) and quality of life (QoL), and identification of predictors of disease progression and survival.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The key goal of EUROSCA-NHS is to determine and compare the rate of disease progression in SCA1, SCA2, SCA3 and SCA6. To this end, a newly developed and validated ataxia scale (Scale for the Assessment and Rating of Ataxia, SARA) will be used. EUROSCA-NHS has a number of secondary aims including determination of the order and occurrence of non-ataxia symptoms, assessment of activities of daily living (ADL) and quality of life (QoL), and identification of predictors of disease progression and survival. Substudies will deal with the development of brain atrophy, as assessed by magnetic resonance imaging (MRI), progression of peripheral neuropathy, as assessed by nerve conduction studies, and specific clinical aspects of SCA.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Spinocerebellar ataxia type 1,2,3 and 6
Spinocerebellar ataxias (SCA) are autosomal dominantly inherited progressive ataxia disorders. An epidemiological study performed in the Netherlands found a prevalence of 3.0 : 100,000 (van de Warrenburg et al. 2002). The SCA´s are genetically and clinically heterogeneous disorders with SCA1, SCA2, SCA3 and SCA6 being the most frequent genotypes worldwide. While SCA1, SCA2 and SCA3 have a complex phenotype, SCA6 patients usually present with pure cerebellar ataxia (Schols et al. 2004). Although precise knowledge of the rate of disease progression is a prerequisite for the biometrical design of future therapeutical trials, prospective studies of the natural history of SCA´s have not been performed. Similarly, the occurrence and evolution of accompanying non-ataxia symptoms have not been studied prospectively.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Scale for the assessment and rating of ataxia (SARA)
Time Frame: Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
Progression of ataxia is measured using a newly developed and validated ataxia scale, SARA. 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.
Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease stages
Time Frame: Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
Disease stages are measured using the 5 point scale ranging from 0 to 4 proposed by Klockgether et al., 1998.
Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
Inventory of non-ataxia signs (INAS)
Time Frame: Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
The occurrence of accompanying non-ataxia symptoms is recorded using INAS. In the SARA validation trials, INAS was applied to a large number of SCA patients. Statistical evaluation showed good reliability.
Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
UHDRS part IV
Time Frame: Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
Functional disability in ADL is assessed using the Functional assessment part of the Unified Huntington's Disease Rating Scale (UHDRS) (Huntington Study Group, 1996). This 25-item assessment has been used in SCA patients throughout the SARA validation study with good practicality.
Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
EQ-5D
Time Frame: Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
Health related Quality of life is assessed using EQ-5D, a generic instrument that has been developed and validated by the EuroQuol Group (1990) and is available in validated translations for use as a questionnaire.
Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
PHQ-9
Time Frame: Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.
Assessment of depressive symptoms is done using a validated 9-item short form of the Patient Health Questionnaire (PHQ), a questionnaire that has been developed to screen for psychiatric co-morbidity in unselected populations (Spitzer et al. 1999).
Patients are first seen at a baseline visit, followed by annual visits for 3 years scheduled ± 3 months around the specified time point. After the initial 3 year observation period, visits are done at irregular intervals each time they went to hospital.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
