  Purpose

The primary objectives of this study are to assess the safety and immunogenicity of extended treatment with Daclizumab High Yield Process (DAC HYP). The secondary objective is to assess the durability of the effect of DAC HYP on multiple sclerosis (MS) disease activity as measured by brain magnetic resonance imaging (MRI) scans and clinical MS relapses.

Primary Outcome Measures:
  • Number of participants with Adverse Events and abnormal Laboratory Evaluations, Vital Signs and Physical Examinations [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: Yes ]
  • Number of participants with development of antibodies to DAC HYP [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Annualized relapse rate [ Time Frame: Up to 72 weeks ] [ 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 by tabulating the total number of relapses experienced in the group divided by the number of days up to the end of study, and the ratio then multiplied by 365.

  • The percentage of participants who are relapse free [ Time Frame: Up to 72 weeks ] [ 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 number of new Gadolinium-enhancing lesions [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: No ]
    Evaluated by magnetic resonance imaging (MRI) by a central reader.

  • The number of new or newly-enlarging T2 hyperintense lesions [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: No ]
    Evaluated by magnetic resonance imaging (MRI) by a central reader.

  • The volume of new T1 hypointense lesions [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: No ]
    Evaluated by magnetic resonance imaging (MRI) by a central reader.

  • The total lesion volume of T2 hyperintense lesions [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: No ]
    Evaluated by magnetic resonance imaging (MRI) by a central reader.

  • The volume of non-Gadolinium-enhancing T1 hypointense lesions [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: No ]
    Evaluated by magnetic resonance imaging (MRI) by a central reader.

  • Total brain volume [ Time Frame: Up to 72 weeks ] [ Designated as safety issue: No ]
    To assess brain atrophy, total brain volume will be measured by magnetic resonance imaging (MRI) and analyzed by a central reader.

Detailed Description:

This study is an extension to the Daclizumab High Yield Process (DAC HYP) therapy from Study 205MS201 (NCT00390221) to evaluate the long-term safety, efficacy, and immunogenicity of DAC HYP in multiple sclerosis (MS). In Study 205MS201, study treatment was scheduled to stop at the Week 52 visit. This extension study will provide for the initiation of active therapy with DAC HYP among participants who received placebo during Weeks 0 through 52 in 205MS201. In addition, participants who received active therapy with DAC HYP during Weeks 0 through 52 in 205MS201, will continue DAC HYP therapy or resume DAC HYP therapy after a 6-month washout period in this study.
