Longitudinal Study of Ultra-rare Inherited Metabolic and Degenerative Neurological Diseases.

November 15, 2024 updated by: Fondazione I.R.C.C.S. Istituto Neurologico Carlo Besta

Clinical, Instrumental and Laboratory Data Collection of Subjects with Ultra-rare Inherited Metabolic and Degenerative Neurological Diseases

General aim of the study is the improvement of the clinical knowledge of ultra-rare inherited metabolic and degenerative neurological diseases (prevalence less than 5:100,000) in adulthood through the systematic longitudinal collection of clinical, laboratory and instrumental data.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study provides a collection of retrospective data from adult patients with ultra-rare inherited neurological diseases followed at "Carlo Besta" Neurological Institute from 1st January 2004 until March 2021. Further, prospective data will be collected starting from March 2021 (date of protocol approval) and spanning the next ten years. Normal clinical practice will be followed for collection of the prospective data. Follow-up assessment will be performed at least once a year to evaluate the disease course. Based on their clinical manifestations, patients will be assessed by using quantitative functional tests (clinimetric tests such as Timed Up and Go Test) and traditional ordinal scales (such as the scale for the assessment and rating of ataxia (SARA). Moreover, a varying of laboratory and instrumental tests (e.g., neuroimaging, neurophysiological investigations, etc.) will be used according to clinical practice in selected patients.

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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2021

Primary Completion (Estimated)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
