Analysis of a Biomarker Signature in Patients With Multiple Sclerosis (MS) Treated With Gilenya (FTY720) (MS)

April 2, 2015 updated by: David Haegert, McGill University

Analysis of a Biomarker Signature, Consisting of Toll-like Receptor 2 (TLR2), TLR4 and CCR1, by Flow Cytometry in Patients With MS Treated With Gilenya (FTY720)

This study investigates whether there is a link between disease activity/progression in patients receiving Gilenya and expression of a putative biomarker signature in patients with multiple sclerosis.

Study Overview

Status

Unknown

Conditions

Detailed Description

Gilenya modulates expression of the sphingosine-1-phosphate receptor and inhibits egress of several lymphocyte subsets from lymph nodes. This results in immunosuppression that has a beneficial effect in patients with multiple sclerosis.

Our laboratory reported that increased expression of a possible biomarker signature, consisting of TLR2, TLR4 and CCR1, in a T-subset is associated with rapid MS progression. The investigators will test whether a significant proportion of patients at baseline upregulate this biomarker signature in one or more T-subsets, whether expression of this biomarker signature changes with treatment with Gilenya and whether expression levels of this signature predict disease activity or progression over a 12 month followup period. The investigators will study patients who are already being treated with Gilenya by their neurologists or who are already being treated with Gilenya as part of a clinical trial sponsored by Novartis Pharmaceuticals Canada. Patients will not be treated with Gilenya for the purposes of our study.
