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.

Study Overview

• Status: Completed
• Conditions: Clinically Isolated Syndrome; Relapsing-remitting Multiple Sclerosis

Detailed Description

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.

Study Population

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.

Description

Inclusion Criteria:

• male and female patients between the ages of 18-55 years inclusive
• have provided informed consent to be screened for the study
• have been diagnoses as having MS
• meet the McDonald diagnostic criteria for RRMS or CHAMPS criteria for CIS
• have an EDSS score of 0.0-3.5
• have had no immunomodulator or cytoxic agents and have had no steroids or other immunosuppressants within 30 days prior to Baseline Visit
• must have had a brain MRI scan demonstrating lesions consistent with MS on T2-weighted or FLAIR images
• subjects must be willing and able to participate in all aspects of the study, including use of study medications as prescribed, and screening and follow-up clinical and MRI assessments

Exclusion Criteria:

• type I of type II diabetes
• uncontrolled hypertension (systolic >160 or diastolic >100 despite medication therapy)
• history of suicidal ideation
• history of psychosis

• abnormal laboratory results indicative of significant hepatic, renal, hematopoetic, or coagulation dysfunction
• the entity of any disease entity, which in the opinion of the investigators would potentially prevent the patient from successfully completing 2 years participation in this trial or confound the observations made during this trial
• prior use of Avonex, Betaseron, Rebif, mitoxantrone, cyclophosphamide, azothioprine, methotrexate, cladribine, cyclosporin, CellCept, IVIG, natalizumab, anti T-cell or anti B-cell antibodies, plasmapheresis or other systemic immunosuppressant or cancer chemotherapeutic agents
