Trial summary

This study aims to identify clinical, biological, imaging, and environmental factors that predict the progression and severity of Multiple Sclerosis (MS). We will establish a prospective, highly phenotyped cohort of patients diagnosed with MS according to the 2024 criteria, regardless of disease form or stage. Read more about this study

About this study

Official title: Disability Progression in Multiple Sclerosis: Determinants, Pathophysiology, and Global Health Impact

This study aims to identify clinical, biological, imaging, and environmental factors that predict the progression and severity of Multiple Sclerosis (MS). We will establish a prospective, highly phenotyped cohort of patients diagnosed with MS according to the 2024 criteria, regardless of disease form or stage.

We hypothesize that combining neurological, vascular, metabolic, neuropsychological, environmental, and imaging data (from the central nervous system and the eye) will improve the identification of markers associated with MS progression. This integrative approach will help clarify the respective roles of inflammation, vascular dysfunction, myelin repair, and neurodegeneration in disability accumulation.

The study will also evaluate the impact of MS, disability, and treatments on patients' physical, mental, and social health, as defined by the World Health Organization (WHO). These results are expected to support personalized patient management and identify modifiable risk factors to reduce disability and inform future therapeutic strategies.

The primary objective is to identify factors that worsen neurological disability in MS patients, including disease-related, comorbidity, and environmental factors. The main outcome measure is time to confirmed disability accumulation (CDA), defined as an increase in the EDSS (Expanded Disability Status Scale) score confirmed after at least 3 months.

This single-center, 5-year prospective cohort study will be conducted at Hôpital Fondation Adolphe de Rothschild (Paris, France), with annual visits. A linkage with national health data (SNDS) will be established for both MS patients and a matched control group (5:1 ratio).

Additional research procedures include:

Ophthalmologic exams (OCT, angio-OCT, fundus photography, pupillometry) at baseline, year 1, 3, and 5.

Brain MRI with additional non-contrast research sequences (annual).

Clinical assessments including arterial stiffness and hearing tests.

Blood sampling (up to 40 mL) for biomarker analyses and long-term biobanking (25 years).

Lumbar puncture if clinically indicated at baseline (with extra samples for research).

Physical activity and circadian rhythm monitoring using a wrist accelerometer for 9 consecutive days.

Standardized questionnaires assessing quality of life, education, and social/professional impact.

Inclusion criteria:

Age ≥ 18 years

Diagnosis of MS according to 2024 criteria

Medical subject headings
Multiple Sclerosis

What is being measured

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

  1. Confirmed disability accumulation (CDA)

    The primary endpoint will be time to confirmed disability accumulation. Confirmed disability accumulation (CDA) will be defined as an increase in the Expanded Disability Status Scale (EDSS) score of ≥1.5 points if the previous EDSS score was 0; ≥1.0 point if the previous EDSS score ranged from 1.0 to 5.5; and ≥0.5 point if the previous EDSS score was greater than 5.5 (19). The increase must be confirmed after a minimum of 3 months. Each patient may experience one or several episodes of neurological disability worsening during follow-up.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis, run by Fondation Ophtalmologique Adolphe de Rothschild.

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 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: opening soon, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Confirmed disability accumulation (CDA) (time frame: 5 years). 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 12 Jun 2026.
