Trial summary

The project will study a therapeutic approach in Spinocerebellar Ataxia (SCA38) by DHA replacement. SCA38 is caused by missense mutations in the ELOVL5 (Elongation of very long chain fatty acids protein 5) gene. Read more about this study

About this study

Official title: Translating Molecular Pathology Into a Therapeutic Strategy in SCA38, a Newly Identified Form of Spinocerebellar Ataxia

The project will study a therapeutic approach in Spinocerebellar Ataxia (SCA38) by DHA replacement. SCA38 is caused by missense mutations in the ELOVL5 (Elongation of very long chain fatty acids protein 5) gene.

Background/Rationale: ELOVL5 is a microsomal fatty acid elongase gene required for the synthesis of arachidonic acid and DHA. In brain, it shows a peculiar high expression in cerebellar Purkinje cells.

Read more

The ELOVL5 products, such as DHA, are decreased in SCA38 patients serum and DHA administered as a dietary supplement has been shown to improve SARA scores, to ameliorate quality of life, and to increase brain cerebellar hypometabolism (FDG-PET) in two SCA38 patients.

Experimental Plan: The investigators will perform a randomized placebo-controlled trial by DHA supplementation on ten SCA38 patients, followed by an open-label phase.

Expected results: DHA supplementation should be able to improve symptoms in SCA38 and to improve cerebellar hypometabolism in these patients.

Read the detailed description

Spinocerebellar ataxias (SCAs) include over thirty different subtypes of central nervous system diseases that affect approximately 1 in 30,000 persons. The investigators have identified the causative gene for SCA38, a novel rare form of cerebellar ataxia. Estimated frequency of the disease is below 1% of SCAs. The disease gene encodes an enzyme involved in omega-3 fatty acid biosynthesis, whose products are reduced in SCA38 patients' serum.

The investigators reasoned that the administration of specific omega-3 fatty acids could ameliorate the disease symptoms in SCA38 patients. Indeed, preliminary data obtained in a pilot trial on two patients, now in their 8th-month therapy, are remarkable, with an improvement of disease symptoms and quality of life, without any adverse effect.

The investigators will perform a clinical trial to prove this therapeutic strategy of SCA38. The investigators will evaluate clinical SARA scores, ICARS scores, brain PET images, and plasma metabolic pattern in ten SCA38 patients.

The trial will consist of two phases: 1) a randomized double-blind placebo/treatment (600 mg DHA/day) from T0 (baseline observation) to T1 (evaluation at four-month). Patients who will meet the study eligibility criteria will be randomized to receive the drug or the placebo (ratio 1:1). A second open-label phase on all patients from T2 (6 months) to T5 (30 months) will be performed with repeated measures of the medication group (n=10).

Patients will complete a personal diary during the whole treatment and a quality of life questionnaire at each visit. The primary outcome will be the clinical improvement, whilst secondary outcome will be considered the improvement of brain metabolism by PET-FDG.

At each time point, clinical evaluation (video-record of SARA/ICARS scores) will be performed. Videos will be randomized and evaluated blindly by two independently clinicians.

At T0, T1, T2, T5, patients will undergo brain PET-FDG scan. PET-FDG scans will be performed by the same scanner at the University of Brescia.

This project will provide helpful data on possible replacement treatment in this novel form of cerebellar degeneration.

Questions about this trial

What is this clinical trial studying?

A study testing DHA in people with SCA38, run by Barbara Borroni at 1 site in Italy.

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 2 inclusion and 7 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 31 Dec 2018. 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 Italy. 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. Some participants in this study may receive a placebo. 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.

What does the primary outcome measure?

Change from Baseline SARA score at 16 weeks and 40 weeks (time frame: baseline, 16 weeks, 40 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03109626, which also lists 1 linked publication.

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 31 Dec 2018.
