Outcomes
Primary outcome [1] 1866 0
The primary objective of this study is to determine the relationship between 3 different doses of daclizumab high yield process (DAC HYP) on brain lesion activity as measured by magnetic resonance imaging (MRI) in subjects with relapsing-remitting MS when compared to placebo. The primary endpoint is the total number of gadolinium (Gd) enhancing lesions over 5 brain MRI scans.

Other unspecified reasons that, in the opinion of the Investigator and/or Biogen Idec, make the subject unsuitable for enrollment.

Summary
Brief summary
The purpose of the study is to determine whether or not 3 different doses of DAC HYP are effective in decreasing the number of abnormal spots (lesions) on brain magnetic resonance imaging (MRI) scans and in delaying the progression of MS, and to test the safety of DAC HYP in patients with relapsing-remitting MS.
This is a double blind, parallel group study where subjects will receive either placebo, or Dac HYP 25mg, 100 mg or 200 mg every 4 weeks by subcutaneous injection for 52 weeks.
