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

September 3, 2009 updated by: Biogen
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.

Description

Inclusion Criteria:

Exclusion Criteria:

  • considered by the Investigator to be immunocompromised
  • history of, or available abnormal laboratory results indicative of any major disease that would preclude the administration of a recombinant humanized antibody immunomodulating agent for the duration of the study.
  • condition(s) considered to be contraindication(s) for plasma exchange, including but not limited to bleeding diathesis, hypotension, or vascular access limitations
