RT Journal Article SR Electronic T1 Experimental therapies for multiple sclerosis: current status JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 63 OP 74 VO 59 IS 1 A1 Donald E. Goodkin A1 Richard M. Ransohoff A1 Richard A. Rudick YR 1992 UL http://www.ccjm.org/content/59/1/63.abstract AB Multiple sclerosis is the most common cause of nontraumatic disability affecting young adults in the United States. Its etiology remains unclear, but evidence points to alteration of normal immune system function in the pathogenesis of this illness. This article reviews the results of clinical trials of experimental therapeutic agents in multiple sclerosis. The background and action of each treatment are described, and the clinical experience with each agent is reviewed. Obstacles to evaluating the effectiveness of treatment methods in MS and challenges to the design of future clinical trials and the interpretation of trial outcomes are discussed.
