Understanding the 'Durable Effect' Concept of B-cell Modulating Therapies

RecruitingN/A

Sponsor: Heinrich-Heine University, Duesseldorf

Conditions: Relapsing-remitting Multiple Sclerosis

Interventions: Anti-CD20 antibody

Countries: Germany

This prospective, observational clinical study aims to longitudinally assess peripheral immune cell profiles of patients with relapsing-remitting multiple sclerosis (RRMS) receiving anti-CD20 therapy with ofatumumab (OFA), ocrelizumab (OCR), ublituximab (UBX), and rituximab (RTX). Throughout the study, clinical data - including relapse events, patient scores, and neuropsychological parameters - will be collected, along with results from imaging techniques such as Optical Coherence Tomography (OCT) and Magnetic Resonance Imaging (MRI). This clinical data will be combined with immunological analyses, including multidimensional flow cytometry (mFC), bulk RNA sequencing (bulk-Seq), T and B cell receptor sequencing (TCR/BCR-Seq), proteomics, and immunoglobulin analysis. This approach aims to enable a detailed characterization of changes in the immune cell repertoire and their impact on the clinical disease course.
