Interferons are a group of endogenous glycoproteins, that are bestowed with immunomodulatory, antiviral and antiproliferative properties. Rebif (interferon beta-1a) shares the same amino acid sequence with endogenous human interferon beta.
The efficacy of Rebif has been calculated in patients with relapsing-remitting Multiple Sclerosis at certain doses ranging from 11 to 44 micrograms (3-12 million IU), administered subcutaneously (three times per week). Rebif 22 mcg has been observed to minimize the incidence (approximately 30% over 2 years) and severity of clinical relapses in patients with at least 2 exacerbations in the previous 2 years along with an EDSS of 0-5.0 at entry. The average count of patients with disability progression, as defined by at least one point increase in EDSS confirmed three months later, was decreased from 39% (placebo) to 30% (Rebif 22 mcg).
The active ingredient in Rebif injection is Interferon beta-1a, and the inactive ingredients are albumin (human), mannitol, sodium acetate and water for injection.
