Trial summary

The autosomal dominant spinocerebellar degenerations are a highly heterogeneous, clinically and genetically, group of rare diseases and of severe evolution. So far, the responsible genes for less than 50% of the cases are known and because of their rarity, there are no phenotype-genotype correlations and well-defined… Read more about this study

About this study

The autosomal dominant spinocerebellar degenerations are a highly heterogeneous, clinically and genetically, group of rare diseases and of severe evolution. So far, the responsible genes for less than 50% of the cases are known and because of their rarity, there are no phenotype-genotype correlations and well-defined disease history.

The aims of the project are to develop and validate quantitative tools of the cerebellar syndrome and of the spasticity, to establish links between the phenotype and the result of the molecular analysis, to identify new loci/genes responsible for these disorders, and to establish the natural history of the disease according to the genotype.

To this end, a prospective and multicentric study is proposed for recruiting and evaluating, clinically, a cohort of 225 patients; 150 of them are already followed-up in the centers involved. A DNA collection will be set up in order to search for the implication of new loci and genes. A clinico-genetic database will be set up combining data from successive clinical evaluations and those of genotyping.

This strategy will allow access to genetic counselling and molecular diagnosis (positive, presymptomatic or prenatal diagnoses), based on a rational strategy from phenotype-genotype correlations and the information concerning the relative frequency of the genes. The detailed description, with the help of new evaluation tools and of the follow-up of the natural history of the disease according to the genotype, constitutes a crucial step in the design of therapeutical trials in these orphan disorders. Furthermore, the regular follow-up by specialized centers will allow better care of the patients.

What is this clinical trial studying?

An observational study of Spinocerebellar Ataxias and Spastic Paraplegias, run by Institut National de la Santé Et de la Recherche Médicale, France at 8 sites in France.

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 3 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: finished, as of the sponsor's last update on 25 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00136630, which also lists 13 linked publications.

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 25 Aug 2021.
