A Multicenter Study to Assess the Effect of Plasma Exchange in Accelerating the Clearance of Natalizumab in Subjects With Multiple Sclerosis (MS) - Full Text View

Purpose

Natalizumab (TYSABRI) is a protein-based drug that is manufactured by Biogen Idec in partnership with Elan Pharmaceuticals. Natalizumab is approved in the US and Europe for the treatment of Multiple Sclerosis (MS). The purpose of this study is to determine whether the amount of natalizumab (TYSABRI) that is present in your blood (plasma) can be reduced or eliminated by separating and removing the plasma and replacing it with other fluids, a process called plasma exchange.

Criteria

Inclusion Criteria:

considered by the Investigator to be free of signs and symptoms suggestive of any serious opportunistic infection
willing to discontinue and remain free from concomitant immunosuppressive or immunomodulatory treatment (including interferon beta and glatiramer acetate) for the duration of the study
willing and able to comply with the site's plasma exchange protocol which may require hospitalization or daily visits
