Clinical characteristics of middle-aged and older patients with MS treated with interferon beta-1b: post-hoc analysis of a 2-year, prospective, international, observational study.

Background Despite trends towards the increased age of patients living with multiple sclerosis (MS), little is known about the response of older adults with MS to disease-modifying therapies (DMTs). Thus, a post-hoc analysis was undertaken using data from a 2-year, international, non-interventional, prospective cohort study ({"type":"clinical-trial","attrs":{"text":"NCT00787657","term_id":"NCT00787657"}}NCT00787657; BEACON: BEtaferon prospective study on Adherence, COping and Nurse support) of patients above the age of 40 years with MS and starting interferon beta-1b (IFNB-1b) treatment within 6 months before study entry.
