About this study

The aim of this study is to obtain an early biomarker of amyotrophic lateral sclerosis and Friedreich's Ataxia which allows to diagnose the disease in an initial stage and to follow up the patient with optic coherence tomography, a fast, non-invasive and comfortable method

Read the detailed description

All patients will be asked about their data and their general medical history, and will be underwent on one hand, a complete neurological examination including the degree of neurological impairment quantified according to the functional rating scale of ALS (ALSFRS-r) or Scale for the assessment and rating of ataxia (SARA); On the other hand, they will have a complete ophthalmological examination too, including the patient's graduation, pupillary and ocular motility examination, biomicroscopy, Goldman tonometry and fundus exam. Patients will be performed too a conventional automated Humprey perimetry, color test (Farnsworth-Munsell 28 Hue Color Vision Test) and finally an optical coherence tomography (OCT) in order to see possible anatomical alterations in both macula and optic nerve. The follow-up of these explorations will be repeated in all cases at 6 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Amyotrophic Lateral Sclerosis, run by Jose Luis Urcelay Segura at 1 site in Spain.

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 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 26 Feb 2019. 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 Spain. 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?

Results are not available in the source record.

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

Contact Pilar Rojas, MD (+34616042758, pilar.rojas.lozano@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

early biomarker of amyotrophic lateral sclerosis and Friedreich's Ataxia (time frame: change from baseline to 6 month). 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 26 Feb 2019.
