Condition(s) targeted: Clinically Isolated Syndrome

Intervention: Rebif® (Drug); No Treatment (Other)

Phase: Phase 3

Status: Completed

Sponsored by: Merck KGaA

Official(s) and/or principal investigator(s):
Medical Director, Study Director, Affiliation: EMD Serono Canada Inc.


The primary objective of this initiative is to assess the effectiveness of subcutaneous (sc)

interferon (IFN) beta - 1a, (Rebif), versus No Treatment in delaying the conversion to

Clinically Definite Multiple Sclerosis (CDMS) - as defined by the occurrence of a second

exacerbation - over 96 weeks in subjects that present with Clinically Isolated Syndrome

(CIS) accompanied by an abnormal magnetic resonance imaging (MRI). The secondary objectives are to:

- Assess the effectiveness of sc IFN beta - 1a (Rebif) therapy in reducing the

proportion of patients with CIS converting to CDMS

- Assess the safety of sc IFN beta - 1a (Rebif®) in the patients with CIS
