Identification of Retinal Perivascular Inflammation in Patients With

Status Not yet recruiting

Clinical Trial Summary

Using a technique called adaptive optics imaging applied on retina, investigators aim to gain access to vascular changes that could occur early in the course of Multiple Sclerosis (MS) and which could reflect vascular changes occurring along the optic nerve of the brain parenchyma. Indeed, our team has been able to develop a quantitative method to measure the perivascular infiltrate in the retina of patients with various inflammatory retinal disease. It has been observed in MS patients that this perivascular infiltrate can also be detected in the retina. However, its distribution across MS phenotypes (relapsing or progressive MS, with and without optic neuritis) is still unknown.

Clinical Trial Description

This is a monocentric pathophysiological, interventional, prospective, open label, non-randomized pilot study which aims to identify in patients with MS at different stages if the presence of retinal perivascular inflammation can be detected and quantified using adaptive optics, which is a non-invasive examination.

Investigators will recruit MS patients in 3 subgroups, depending on their phenotype (Relapsing Remitting Multiple Sclerosis (RRMS) without optic neuritis, RRMS with optic neuritis, progressive MS), with 15 patients in each group.

15 healthy volunteers (HV) will also be enrolled.

The comparison of these groups is necessary to determine if there are significant differences, allowing us to highlight biomarkers in MS patients in order to enable highly efficient and robust trials designs in the future.

To test the hypothesis, the study has 3 visits over 6 months (M0, M3 and M6). Neurological evaluation, blood sample, imaging, ophthalmologic evaluation and Adaptive optics ophthalmoscopy assessments will be performed. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
