The clinical trials related to multiple sclerosis currently in progress or recently concluded include studies of interferon beta agents in secondary progressive multiple sclerosis, glatiramer acetate in primary progressive multiple sclerosis, and oral agents or combination treatment in relapsing-remitting multiple sclerosis. An additional two to three multicenter clinical and epidemiological trials are currently being planned for the study of long-term and symptomatic care of patients with multiple sclerosis.
An NIH-sponsored General Clinical Research Center is available for approved investigations.
