Safety/Effectiveness of Adding Monthly Dexamethasone to Weekly Avonex for MS
Steroid Adjunctive Treatment at Initiation of Avonex Therapy for Patients With Mono-Symptomatic or Relapsing-Remitting Multiple Sclerosis

The purpose of the study is to determine whether giving intravenous dexamethasone every 4 weeks during the first 12 months of weekly Avonex dosing will reduce the progression of functional impairment, brain atrophy, relapse rate and frequency, and new and enlarging brain lesions over the first 24 months of Avonex therapy in patients with relapsing-remitting or mono-symptomatic multiple sclerosis.

Beta Interferon-1a (Avonex)was approved by the FDA in 1996 to treat relapsing-remitting multiple sclerosis. Clinical trials have shown evidence in the reduction of relapses and progression of neurological and cognitive disability with the use of Avonex, as well as reduction in brain atrophy and new MS lesions on MRI were observed. Despite this, Avonex does not abolish disease activity, therefore, there is frequent need for adjunctive therapy, such as short courses of corticosteroids.

This study will research the value of adding monthly pulsed corticosteroids as adjunctive therapy during the first year of Avonex use to determine: a)safety and tolerability b)if this therapy will reduce the progression of functional impairment, and c)if this therapy will reduce the progression of whole brain atrophy over a 13 month observation period.

Non-Probability Sample

Treatment-naive MS patients with either RRMS or CIS, of either gender, between 18 to 55 years of age inclusive, with baseline EDSS of 0 to 3.5, fulfilling McDonald criteria for MS or CHAMPS criteria for CIS, were randomly assigned to one of two treatment groups.

  • Relapsing-remitting Multiple Sclerosis
  • Clinically Isolated Syndrome
Not Provided
  • IFNβ+DS group
    IFNβ+DS group received lyophilized Avonex 30mcg IM weekly plus dexamethasone 160 mg IV every 4 weeks for 52 weeks and was treated with Avonex 30mcg IM weekly from week 53 to 104
  • IFNβ group
    IFNβ group received lyophilized Avonex 30mcg IM weekly for 104 weeks
