Brief Summary
The purpose of this study is to determine the safety, tolerability and efficacy of a
combination therapy interferon beta-1a(Avonex) plus simvastatin (Zocor) vs. interferon
beta-1a plus placebo in patients with clinically isolated syndrome suggestive of Multiple
Sclerosis.
Detailed Description
Interferon beta-1a (IFNB-1a), a FDA approved therapy for relapsing-remitting (RR) MS has
several mechanisms of action. It lowers proinflammatory cytokine production and inhibits
antigen presentation by class II major histocompatibility complex (MHC) molecule. It also
reduces metalloproteinase activity, which all lead to decreased migration of T-lymphocytes
into the central nervous system (CNS), and subsequent inhibition of inflammatory lesion
formation. We propose that combination therapy during early stages of the disease with
second immunomodulatory agent that targets different steps in the pathogenesis of the
disease may add to the effectiveness of IFNB-1a. IFNB-1a administered intramuscularly at 30
mg per week is particularly suitable for combination therapy due to its proven efficacy in
Clinically Isolated Syndrome (CIS),favorable safety profile and low frequency of
neutralizing antibodies (NABs) against IFNB-1a in comparison to other forms of IFNB-1a.
Recent studies have reported a significant anti-inflammatory and neuroprotective effects of
statins, cholesterol-lowering agents. Statins disrupt cellular membrane lipid rafts, which
inhibit the clustering of T-cell receptor (TCR), co-stimulatory, and adhesion molecules,
required for optimal T-cell activation. Along with inhibiting T-cell activation, statins
decrease IFNB inducible MHC class II expression, suppressing an effective antigen
presentation. They block migration of activated mononuclear cells from peripheral
circulation into the CNS by blocking LFA-1 adhesion molecule and by reducing
metalloproteinase type 9 secretion. While their anti-inflammatory effects at tolerable oral
doses may not justify their use as monotherapy for RR MS, their pleiotropic mechanisms of
action showed synergistic effects with IFNB-1a in studies in vitro. We propose that
simvastatin may enhance the immunomodulatory effects of INFB-1a in patients with CIS
suggestive of MS and that this combination may even more effectively prevent further disease
activity if administered early in the course of the disease.
