This independent, population–based surveillance study monitored the efficacy and safety of interferon beta (IFNß) products in 1033 patients with relapsing-remitting multiple sclerosis (RRMS) from 15 centres in Italy.

Relapses, Expanded Disability Status Scale (EDSS) scores, and adverse events were evaluated for up to 24 months.

Data of patients with a baseline EDSS score 3.5 are reported.

The proportions of relapse-free patients were similar among the groups at 12 and 24 months (P=0.10).

IFNß products produced significant reductions from baseline in relapse rates at 12 and 24 months (P<0.001), with no differences among treatments (P=0.2).

There were no significant differences in mean EDSS change among groups at 12 or 24 months.

The IFNß-1b group showed a higher incidence of adverse events during the first year of treatment (P<0.05) than IFNß-1a groups, and more withdrawals (10%) compared with Avonex (5%) at 24 months.

IFNß products are equally effective in low disability RRMS, but IFNß-1a may have a more favorable efficacy/tolerability ratio.
