The participant will receive weekly intramuscular treatment with AVONEX® (interferon beta 1-a) and bi-monthly high dose intravenous methotrexate with Leucovorin rescue.
The participant will receive weekly intramuscular treatment with AVONEX® (interferon beta 1-a) and bi-monthly high dose intravenous methotrexate with Leucovorin rescue. Entrance into the study will be based on Multiple Sclerosis Functional Composite Score (MSFC) evaluations at -4 months, and - 1 month prior to study, where a decrease in score is noted. The composite score consists of the Timed 25-Foot Walk, Nine-Hole Peg Test (9HPT), and Paced Auditory Serial Addition Test 3 (PASAT 3). The patient must have been on AVONEX® for at least 6 months.
At study entrance, baseline lab work (complete blood count, platelet count, routine electrolytes, blood urea nitrogen, creatinine, liver function tests, 24 hour urine collection for creatinine clearance, and urine pH), an electrocardiogram (measurement of heart activity) and serum pregnancy test will be done. A complete physical examination will be performed, including measurements of vital signs (heart rate and blood pressure), as well as magnetic resonance imaging (MRI) to document status of disease. A self-administered questionnaire, the MSQLI (Multiple Sclerosis Quality of Life Instrument), will be completed at baseline and at the end of the study. MSFC and safety evaluations (previously mentioned blood and urine tests and electrocardiograms (EKG), will be conducted throughout the study at months 2, 4, 6, 8, 10, and 12. Blood tests of immune cells will also be drawn at these visits. The patient can continue this regimen of treatment at their own discretion and cost, and outside the parameters of this study, if there is apparent efficacy without serious adverse events. This treatment would be under the supervision of Dr. Rowe.
The patients will continue their AVONEX® intramuscular injections of 30 micrograms (administered by patient or caregiver) on a weekly basis with scheduled intravenous high dose methotrexate at 2 Gm/m2 followed by intravenous and oral leucovorin rescue once every 2 months. The methotrexate infusions will be performed in our outpatient infusion center. The patient will be required to complete a patient diary during the course of the trial, participate in and keep all scheduled appointments, and to inform the research staff and physician of any change in concomitant medications or adverse events that they may experience.

A non-glycosylated form of interferon beta-1 that has a serine at position 17. It is used in the treatment of both RELAPSING-REMITTING MULTIPLE SCLEROSIS and CHRONIC PROGRESSIVE MULTIPLE SCLEROSIS.
An interferon beta-1 subtype that has a methionine at position 1, a cysteine at position 17, and is glycosylated at position 80. It functions as an ANTI-VIRAL AGENT and IMMUNOMODULATOR and is used to manage the symptoms of RELAPSING-REMITTING MULTIPLE SCLEROSIS.
A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. (From Ann Neurol 1994;36 Suppl:S73-S79; Adams et al., Principles of Neurology, 6th ed, pp903-914)
Interferon secreted by leukocytes, fibroblasts, or lymphoblasts in response to viruses or interferon inducers other than mitogens, antigens, or allo-antigens. They include alpha- and beta-interferons (INTERFERON-ALPHA and INTERFERON-BETA).
A ubiquitously expressed heterodimeric receptor that is specific for both INTERFERON-ALPHA and INTERFERON-BETA. It is composed of two subunits referred to as IFNAR1 and IFNAR2. The IFNAR2 subunit is believed to serve as the ligand-binding chain; however both chains are required for signal transduction. The interferon alpha-beta receptor signals through the action of JANUS KINASES such as the TYK2 KINASE.

Multiple sclerosis (MS) is the most common disabling neurological condition affecting 100,000 young adults in the UK. The condition results from autoimmune damage to myelin, causing interference in nerve signaling. Symptoms experienced depend on the pa...
