Trial summary

Spinocerebellar ataxias (SCA) 1, 2, 3 and 6 are the most common, autosomal dominantly inherited cerebellar degenerations. And in the Chinese population, the most common SCA is SCA3 and the frequency of SCA 3 among SCA patients is 72.5%, followed by SCA 2 that the frequency is 12% among SCA patients.

About this study

Spinocerebellar ataxias (SCA) 1, 2, 3 and 6 are the most common, autosomal dominantly inherited cerebellar degenerations. And in the Chinese population, the most common SCA is SCA3 and the frequency of SCA 3 among SCA patients is 72.5%, followed by SCA 2 that the frequency is 12% among SCA patients. For SCA 1, the frequency among SCA patients is 7%. Even SCAs are rare diseases, a significant amount of Chinese in Hong Kong still suffer from this disorders. SCA Association in Hong Kong has 88 members who are suffering from spinocerebellar degeneration, many of them have a genetic confirmation. As there are few treatments for SCAs; therefore, understanding SCAs clinical manifestation and disease mechanisms are the first step towards development of effective treatment. The objective of this study is to develop the first SCA registry in Hong Kong with bio-repository bank for clinical and genetic information as well as serum and fibroblasts.

Read the detailed description

All the members from Hong Kong SCA association will be invited and discuss the study with them. After obtaining the informed consent, their genotypes will be determined and collect clinical information. Some of the participant will have clear genotyping via Department of Health. Participants with a genetic confirmation of SCA1, 2, 3, 6, 7, 8 and 12 genes will be included in the study. The relatives of genetically confirmed participants, who also had ataxic symptoms, might be included in the study without further determination of the genotypes.

Detailed clinical history including age of onset, clinical symptoms will be collected. A detailed neurological examination with an emphasis of eye movements (such as pursuit, saccadic, and convergence eye movements). We will also perform SARA scale, a validated ataxia scale. Timed 25 foot-walk test will be performed.

Two-year annual follow-up will be arranged for recruited subject for neurological physical examination, SARA scale, in order to continue assessment for any progress change in disease stage.

    No intervention but clinical assessement for all recruited subjects

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Scale for the assessment and rating of ataxia (SARA) score

    Scale for the assessment and rating of ataxia (total score 0-40)

    Measured: change from baseline to 2-year follow up

Secondary outcomes (2)
  1. EQ5D Health questionnaire

    EQ-5D is a standardized instrument for measuring generic health status. The health status measured with EQ-5D is used for estimating preference weight for that health status (1-3 in each health status , 0-100 in general today's health status)

    Measured: change from baseline to 2-year follow up

  2. Patient Health Questionnaire-9 (PHQ-9)

    Depression scale (0-4 in each items)

    Measured: change from baseline to 2-year follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Spinocerebellar Ataxia, run by Chinese University of Hong Kong at 1 site in Hong Kong.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 27 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Anne YY CHAN ((852) 3505 1855, yychananne@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Scale for the assessment and rating of ataxia (SARA) score (time frame: change from baseline to 2-year follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Aug 2024.
