Interferon beta-1a is a drug in the interferon family used to treat multiple sclerosis (MS). It is produced by mammalian cells while Interferon beta-1b is produced in modified E. coli. Interferons have been shown to have about a 30–35% reduction in the rate of MS relapses, and to slow the progression of disability in MS patients.
