Safety and Efficacy Study of Daclizumab High Yield Process to Treat Relapsing-Remitting Multiple Sclerosis
Multicenter, Double-Blind, Placebo-Controlled, Dose-Ranging Study to Determine the Safety and Efficacy of Daclizumab HYP (DAC HYP) as a Monotherapy Treatment in Subjects With Relapsing-Remitting Multiple Sclerosis

The purpose of this study is to determine the effect of 2 different doses of daclizumab on reducing relapses in subjects with relapsing-remitting MS.

Primary Objective:

The primary objective of this study is to determine whether Daclizumab High Yield Process, when compared to placebo, is effective in reducing the rate of relapses between baseline and Week 52.

Secondary Objectives:

The secondary objectives are to determine whether Daclizumab High Yield Process is effective in:

  • reducing the number of new Gd-enhancing lesions over 5 brain MRI scans at Weeks 8, 12, 16, 20, and 24 (calculated as the sum of these 5 MRIs) in a subset of subjects.
  • reducing the number of new or newly-enlarging T2 hyperintense lesions at Week 52,
  • reducing the proportion of relapsing subjects between baseline and Week 52,
  • improving quality of life as measured by the Multiple Sclerosis Impact Scale (MSIS)-29 physical score at Week 52 compared to baseline.

Multiple sclerosis (MS) is a chronic disease of the central nervous system that affects approximately 400,000 persons in North America and 365,000 persons in Europe. Daclizumab High Yield Process (DAC HYP) is being co-developed by Biogen Idec Inc. (Biogen Idec) and AbbVie for treatment of MS. Daclizumab (DAC) produced using the AbbVie high-yield process is being investigated as an alternative. This study will determine if DAC HYP is safe and efficacious in subjects with relapsing-remitting multiple sclerosis (MS). A dose exploration placebo controlled study will be performed. Proof of profile will be sought that targeting of the alpha chain of the interleukin-2 receptor (IL-2Ralpha) without concomitant interferon (IFN) is effective in subjects with relapsing-remitting MS.
