Beta interferons improve survival in people with MS

April 12, 2019 / Clinical Pharmacist

Beta interferons improve survival in patients with relapsing-onset multiple sclerosis (MS) when used for at least three years, research has shown. The study, published in Brain (18 March 2019), used data from Canada and France on 5,989 people with relapsing-remitting MS who were naïve to disease-modifying therapies at study entry. During an average of 11 years of follow-up, 32% of people were exposed to beta-interferon for at least six months. Overall, there were 742 deaths due to any cause and, of these 649 were matched with between 1 and 20 controls by country, sex, age, year and disability level at study entry. It was found that those who received beta interferons were 32% less likely to die than unexposed individuals. When stratified by duration, those exposed to at least three years’ beta-interferon treatment had a 56% reduced risk of death while shorter exposure durations were not significantly related with survival.
