Last verified: April 2011
The primary objective of this study is to determine whether combination treatment (adding methylprednisolone to Avonex) reduces progression of disability over 4 years compared to Avonex alone. The study will also investigate whether combination therapy has any impact on the incidence of relapse and brain atrophy as measured by MRI.

Primary Outcome Measures:
  • To estimate the effect interferon-beta-1a in combination with methylprednisolone vs interferon-beta-1a in combination with placebo on the time to onset of disability progression sustained over at least 6 months based on change from randomization in EDSS [ Time Frame: 4 years ] [ Designated as safety issue: No ]

Enrollment: 345
Study Start Date: January 2003
Study Completion Date: November 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
interferon-beta-1a in combination with methylprednisolone
Drug: Interferon-beta-1a (Avonex) plus methylprednisolone
oral administration given on 3 consecutive days, monthly as described in protocol.
Other Name: Avonex
Placebo Comparator: 2
interferon-beta-1a in combination with placebo
Drug: Interferon-beta-1a (Avonex) plus methylprednisolone
oral administration given on 3 consecutive days, monthly as described in protocol.
Other Name: Avonex

Detailed Description:
Approximately 340 therapy-naïve MS patients with relapsing-remitting form of the disease will be randomized to receive Avonex alone or Avonex plus methylprednisolone (MP). Patients will receive MP as 500 mg po for 3 days every month or matching placebo. The patients are followed on a 3-monthly basis for 4 years with disability as the primary parameter of efficacy over that time.
