Study of the Mechanisms of Action of Cladribine in Multiple Sclerosis

NCT04821596 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 77

Summary

The main objective of the project is therefore to study and thus better understand the immunomodulatory / anti-inflammatory effects of cladribine during multiple sclerosis.

Most current and developing therapies targeting the immune system have no effect on the progressive phase of MS, during which neurodegeneration plays a predominant role. As mentioned above, the very promising results of clinical trials with cladribine tablets for the early and progressive phase of the disease have revealed immunomodulatory properties and suggested potential neuroprotective effects.

It therefore plans to further dissect one of these two parameters by designing in vitro studies with peripheral blood mononuclear cells (PBMC) from healthy donors and MS patients.

biological collection

Six 5 mL heparinized tubes, approximately 24 mL of blood will be collected as per standard practice. The 5 tubes collected from a given individual will be transported directly to the laboratory. In the laboratory, peripheral blood mononuclear cells (PBMC) will be prepared for the various analyses. However, in order to minimize the effect of agents other than CoA in MS patients, it is necessary that peripheral blood mononuclear cells are collected before treatment is given: for RR MS patients treated with first-line drugs (IFNβ, glatiramer acetate, teriflunomide and dimethyl fumarate, ...), RR MS patients treated with second-line drugs (natalizumab and fingolimod, ...) and RR MS patients treated with third-line drugs (alemtuzumab, ...).
