Clinical Trial Summary

The primary objective of this study is to determine the proportion of relapsing multiple sclerosis (RMS) participants who experience new and/or increased flu-like symptoms (FLS) after transitioning from nonpegylated interferon beta (IFN-β) therapies to peginterferon beta-1a (BIIB017).

Secondary objectives are: To determine the severity and frequency (measured by flu-like symptom score [FLS-S]) of FLS in these participants; To determine the duration (measured in number of hours) of FLS in these participants; To determine the effectiveness and participants' satisfaction with FLS management as measured by an FLS visual analog scale (FLS-VAS); To determine the effect of peginterferon beta-1a on other participant reported outcomes (PROs) including treatment satisfaction (measured with the Treatment Satisfaction Questionnaire for Medication [TSQM]) and disability status (measured with the Patient Determined Disease Steps [PDDS]) over a 56-week period; To determine whether interferon-related FLS result in missed days of work/daily activities (e.g., absenteeism); To assess the use of additional medications (in addition to current medications used to treat FLS) to relieve peginterferon beta-1a -related FLS; to determine the incidence of adverse events (AEs) throughout the study period; to characterize the immunogenicity profiles of participants switching from prior IFN-β (interferon beta) therapy to peginterferon beta-1a.
