The primary study objective is to test the superiority of Daclizumab High Yield Process (DAC HYP) compared to interferon β 1a (IFN β-1a) in preventing multiple sclerosis (MS) relapse in participants with relapsing remitting multiple sclerosis.

The secondary study objectives are to test the superiority of DAC HYP compared to IFN β-1a in slowing functional decline and disability progression and maintaining quality of life in this participant population.

Primary Outcome Measures:
  • Annualized Relapse Rate(ARR) [ Time Frame: Up to 144 weeks ] [ Designated as safety issue: No ]
    Relapses are defined as new or recurrent neurological 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 ARR will be calculated as the total number of relapses experienced in the treatment group divided by the number of days in the study, and the ratio multiplied by 365.

Secondary Outcome Measures:
  • Number of new or newly enlarging T2 hyperintense lesions on brain MRI [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
    Assessed by magnetic resonance imaging (MRI)

  • Percentage of participants with sustained disability progression [ Time Frame: Baseline and 96 weeks ] [ Designated as safety issue: No ]
    Sustained disability progression is defined as: at least a 1.0-point increase on the Expanded Disability Status Scale (EDSS) from Baseline EDSS ≥1.0 that is sustained for 12 weeks, or at least a 1.5-point increase on the EDSS from baseline EDSS = 0 that is sustained for 12 weeks. The EDSS measures the disability status of people with multiple sclerosis on a scale that ranges from 0 to 10, with higher scores indicating more disability.

  • Percentage of participants who are relapse-free [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
    Relapses are defined as new or recurrent neurological 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.

  • Percentage of participants with a ≥7.5 point worsening from baseline in the MSIS-29 physical score at 96 weeks [ Time Frame: Baseline and 96 weeks ] [ Designated as safety issue: No ]
    The MSIS-29 is a 29-item 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 physical and psychological items. Worsening in the MSIS-29 physical score is defined as an increase of 7.5 points in the MSIS-29 physical score at 96 weeks compared to baseline.
