BENEFIT Study (Betaferon® / Betaseron® in Newly Emerging Multiple Sclerosis for Initial Treatment) and BENEFIT Follow-up Study

Summary

This study will primarily compare the long-term effects of an early and continued treatment with Betaferon/Betaseron (patients who were treated with active medication during the double-blind BENEFIT study) to treatment initiated either after Clinically Definite Multiple Sclerosis (CDMS) has been diagnosed or after two years (those patients who were treated with placebo during the double-blind BENEFIT study). Analyses are based on the integrated data of the initial BENEFIT study and this follow-up study.
