In light of lack of therapy for SPMS patients, the study seeks to determine whether or not Natalizumab is effective in slowing disease progression. Patients will be randomized to either Natalizumab or Placebo in a 1:1 ratio. Placebo use is justified since there are no proven treatment options for SPMS patients. The study duration is 108 weeks and patients will be on study drug treatment for 96 weeks. Study drug will be administered once a month intravenously. Patients will come in for study visits once every 12 weeks (some of which will coincide with standard of care visits), which include neurological examination, EDSS assessment, physical examination, blood draw and urine sample collection, Timed-25-foot-walk test, 9-hole-peg test, 6-minute-walk test, Brain MRI, symbol digit modality test, and response to questionnaires regarding quality of life measures.
