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. The secondary objectives are to determine whether Daclizumab High Yield Process is effective in reducing the number of new gadolinium (Gd)-enhancing lesions, reducing the number of new or newly-enlarging T2 hyperintense lesions, reducing the proportion of relapses and improving quality of life.

Primary Outcome Measures:
  • Annualized Relapse Rate [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Relapses are defined as new or recurrent neurologic symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the examining neurologist. The annualized relapse rate will be calculated as the total number of relapses experienced in the group divided by the number of days up to Week 52, and the ratio multiplied by 365.

Secondary Outcome Measures:
  • Number of new Gd-enhancing lesions [ Time Frame: Weeks 8, 12, 16, 20, and 24 ] [ Designated as safety issue: No ]
  • Percentage of participants with relapses [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Change from Baseline in Multiple Sclerosis Impact Scale (MSIS)-29 physical score [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    The 29-item Multiple Sclerosis Impact Scale (MSIS-29) is a disease specific patient-reported outcome measure that has been developed and validated to examine the physical and psychological impact of MS from a patient's perspective; it measures 20 physical items and 9 psychological items.

  • Number of new or newly-enlarging T2 hyperintense lesions [ Time Frame: 1 year ] [ Designated as safety issue: No ]
