Further study details as provided by Merck KGaA:

Primary Outcome Measures:
  • Proportion of subjects with moderate to severe (grade 3-5) injection site reactions based on pain, bruising and/or transient (<24 hours) erythema; inflammation alone and with induration; necrosis at injection site; plastic surgery required for necrosis [ Time Frame: After 3, 6 and 12 months of Rebif treatment ]

Secondary Outcome Measures:
  • Annual relapse rate [ Time Frame: Baseline to 12 months observation period ]
  • Change in EDSS [ Time Frame: Baseline to 12 months observation period ]
  • Change in MSTCQ [ Time Frame: Baseline to 12 months observation period ]
  • Time to first relapse [ Time Frame: Baseline to 12 months observation period ]
  • Incidence of side effects associated with Rebif therapy [ Time Frame: Baseline to 12 months observation period ]

Enrollment: 60
Study Start Date: August 2008
Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Interferon-β-1a
    Interferon-β-1a according to the standard practice
    Other Name: Rebif®
Detailed Description:

The present observational study is being conducted to assess the safety information from a target of 100 Korean subjects with MS treated with Rebif. Various parameters like subjects' background (age, sex, BMI), MS history, MS status (MS type, Expanded Disability Status Score [EDSS] and others), MS Treatment Concern Questionnaire (MSTCQ), Rebif treatment status, concomitant disease modifying agents (DMA) therapy and Rebif related adverse events will be collected. Subjects will be followed for 12 months. Proportion of subjects with moderate to severe (Grade 3-5) injection site reactions after 3, 6, 12 months of Rebif treatment will be determined. Secondary outcomes like annual relapse rate, change in EDSS, changes in MSTCQ, time to first relapse and incidence of side effects associated with Rebif therapy will also be determined and presented descriptively.


Primary objectives

  • To assess the tolerability of Rebif treatment in Korean MS subjects in a non-interventional setting Secondary Objectives
  • To evaluate subject's satisfaction, clinical data and disease characteristics of the population of MS subjects undergoing Rebif treatment.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
