Visual (Path)Ways in Multiple Sclerosis - Part II (VWIMS - II)

May 14, 2026 updated by: University Hospital, Lille

Evaluation of Neuroaxonal Loss Outside of Any Inflammation in Multiple Sclerosis by a Multimodal Study of the Visual Pathways Model

Multiple sclerosis (MS) is an inflammatory demyelinating and degenerative disease of the central nervous system. The mechanisms of neuro-axonal loss remain incompletely elucidated. An acute demyelinating lesion will produce both immediate and delayed axonal loss. Immediate axonal loss is linked to the occurrence of axonal transection. Delayed axonal loss is the cause of axonal degeneration in progressive MS. Visual impairment is common in the disease (vision, oculomotricity, cognition). Through a longitudinal multimodal analysis of visual pathways, we would like to investigate physiopathological mechanisms leading to neurodegenerative process and visual impairment.

Study Overview

Status

Status

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

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
64

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Other: Not applicable. No treatment will be compared.
During the same visit, we will perform OCT-angiography (10 minutes) and evaluate visual cognition with an eye-tracker (20 minutes)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Quantifying progressive retinal axonal loss in the absence of inflammation
Time Frame: First time point already done (VWIMS study) Second time point during VWIMS -II study. Interval between time points will be around 7-8 years
