Serono's Extensive MS Research Program to Be Featured in Scientific Journals and Presentations This Month

Study of Effectiveness of Rebif(R) in Secondary Progressive Multiple Sclerosis Published in This Week's Neurology

http://www.newswire.ca/releases/June2001/12/c3110.html

GENEVA, June 12 /CNW/ -- Serono S.A.

(SWX Swiss Exchange: SEO and NYSE: SRA) announces that a study of the effectiveness of Serono's Rebif(R) (interferon beta-1a) in the treatment of secondary progressive multiple sclerosis (SPMS) is included in today's issue of Neurology (1,2).  This publication is one of several this month featuring Serono's extensive multiple sclerosis research program.

Serono has conducted clinical trials across the whole pathology of the disease and now has data from over 3,000 patient years of research concerning the safety and efficacy of interferon therapy for the treatment of patients with relapsing MS.

"In our extensive, highly focused research program, we have now extensively examined the relevant aspects of MS in order to identify the optimal treatment for patients," said Ernesto Bertarelli, CEO of Serono, manufacturer of Rebif(R).  "We now have a clearer indication of how to treat patients with MS most effectively."
 
About SPECTRIMS

The SPECTRIMS study (Secondary Progressive Efficacy Clinical Trial of Rebif(R) in MS) published today showed that the effect on delay of disability in patients with SPMS was more pronounced in earlier stages of the disease, when patients are still experiencing relapses, compared with later stages.
 
Other Clinical Studies

Other studies to be featured this month are PRISMS(3) (Neurology, June 2001), in patients with relapsing-remitting MS, and the EVIDENCE (4) study, which complement the recently published ETOMS(5) study (Lancet, May 2001). All of these involve Serono's interferon beta-1a, Rebif(R).

The PRISMS study shows Rebif(R) 44mcg three times a week to be safe and effective over four years for the treatment of patients with relapsing-remitting MS and was originally the basis of regulatory approval in 67 countries. These data together with the published SPECTRIMS and ETOMS studies demonstrate that Rebif(R) is most effective when administered early in patients with relapsing forms of MS.

Further details on all endpoints of the EVIDENCE study will be announced at a platform presentation at the World Congress of Neurology in London on 22 June 2001.

"The implication of these studies," commented Mark S. Freedman, Professor, Department of Medicine, University of Ottawa, Canada, "is that MS patients with relapses can benefit from interferon beta therapy and unquestionably that high doses of Rebif(R) given frequently as early as possible in the disease achieve the best results."
 
More MS Research Data
 
The key publication of Serono's four-year PRISMS study will appear in Neurology on June 26.  The results of the PRISMS long-term study, which forms the basis for regulatory approval of Rebif(R) in 67 countries, demonstrate that the efficacy of Rebif(R) (interferon beta-1a), given at doses of 22mcg three times a week and 44mcg three times a week, is maintained over four years in patients with relapsing remitting MS.  It also shows that the higher dose of 44mcg three times a week is more effective than the lower dose on all major indicators of disability, relapses, MRI (Magnetic Resonance Imaging) burden of disease and MRI disease activity.  The long-term data from this study show that treating early with the highest tolerable dose of interferon beta-1a results in maximum benefit and delay in disease progression.
