Immunosuppression in progressive multiple sclerosis with high dose intravenous cyclophosphamide and monoclonal antibodies

Abstract

Our work with multiple sclerosis has demonstrated a favorable effect on the course of chronic progressive multiple sclerosis in two-thirds of patients treated with cyclophosphamide/ACTH. However, alternative methods of therapy, or repeated treatments with cyclophosphamide and ACTH are required for longer term control of the illness. We are attempting to assess the efficacy of outpatient maintenance cyclophosphamide, but do not as yet have any data to support the use of this form of treatment. Cyclophosphamide and ACTH can be given to multiple sclerosis patients without significant serious toxicity. Monoclonal antibody therapy of multiple sclerosis is in its beginning stages. The treatment appears to be safe and has produced some interesting data indicating that rapid entry of some labeled lymphocytes into the nervous system can be measured by this technique. Since these are phase one pilot trials designed to assess immune parameters and only small numbers of patients have been treated, no clinical results have been obtained. No adverse effects of monoclonal antibody therapy were observed.
