Combining CLA and Probiotics with Immunotherapy for Multiple Sclerosis

Effects of a Combined Supplementation of Conjugated Linoleic Acid (CLA/Tonalin® FFA 80) and Probiotics (Vivomixx®/VSL#3) as add-on to a First-line Immunotherapy in Relapsing-remitting Multiple Sclerosis

Not applicable Interventional Universität Münster · NCT05920018

This study is testing whether adding conjugated linoleic acid and probiotics to standard treatment can help people with relapsing-remitting multiple sclerosis feel better and improve their MRI results.

What this trial studies

This randomized, double-blind, placebo-controlled multicenter study aims to evaluate the safety and effectiveness of combining conjugated linoleic acid (CLA) and probiotics with first-line immunotherapy in patients with relapsing-remitting multiple sclerosis (RRMS). A total of 100 participants will be randomly assigned to receive either the supplements or a placebo alongside their established disease-modifying treatment for 48 weeks. The primary outcome will be the change in volume of T2-weighted hyperintense lesions measured through MRI from baseline to the end of the study period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 with a diagnosis of relapsing-remitting multiple sclerosis who have been stable on first-line disease-modifying treatment for at least six months.

Not a fit: Patients with primary or secondary progressive MS or those on certain other disease-modifying therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the effectiveness of existing immunotherapies for patients with relapsing-remitting multiple sclerosis.

How similar studies have performed: While the combination of dietary supplements with immunotherapy is a novel approach, similar studies have shown promising results in enhancing treatment efficacy in other conditions.
