Abstract
Objectives: To assess if short-term combination of glatiramer acetate (GA) and IV steroid in patients with relapsing–remitting multiple
sclerosis (RRMS) is safe and sustains the effect of GA treatment on MRI-disease activity.
Methods: RRMS patients with ≥ 2 gadolinium (Gd)-enhancing lesions on screening MRI and EDSS score ≤ 4.0 received GA injection
(20 mg subcutaneously once daily) and monthly 1 g IV Methylprednisolone (IVMP) for 6 months. Afterwards, all subjects received GA
injections daily alone for additional 6 months. Neurological evaluations were performed at screening, baseline and every 3 months.
Laboratory tests for safety were performed at screening, baseline, months 1, 6 and 12. Brain MRIs were performed at screening, baseline,
months 5, 6, 11, and 12 to assess the change in the number of Gd-enhancing lesions i) from baseline to month 6, and ii) from baseline to
month 12 compared with the change from baseline to month 6.
Results: 89 subjects were eligible for the study. In this group, GA in combination with IVMP resulted in 65% (95% CI=0.25–0.49,
p b 0.0001) reduction in the number of Gd-enhancing lesions. This reduction was sustained for additional 6 months when patients received
GA alone. The analysis for change achieved in the second 6 month period showed no difference from the change achieved in the first six
months (ratio 0.75, 90% CI = 0.468–1.197). Overall, treatment was well tolerated and adverse events reported were similar to the known
safety profile of GA.
Conclusions: Short-term combination of GA with 1 g monthly IVMP, preceding treatment with GA alone, is safe. MRI data suggest that this
combination therapy may result in an early and sustained reduction of disease activity in RRMS patients.

1. Introduction
All current available disease-modifying treatments
(DMT) for relapsing–remitting multiple sclerosis (RRMS)
are only partially effective on clinical measures of disease
activity and evolution [1]. Three pivotal trials [2–5] and a
meta-analysis of those studies [6] support the benefit of
glatiramer acetate (Copaxone®, GA) 20 mg by daily
subcutaneous injections on relapse rate and magnetic
resonance imaging (MRI) lesion activity in RRMS patients.
A trend toward a potential effect on accumulation of disability
has also been shown [6]. In addition, a long-term open-label
study also demonstrated the safety and tolerability of GA [7].
