6th Case of PML on Tysabri

Oct 29 2008

Two people developed the brain viral infection, PML, recently in Europe on Tysabri without other MS treatments. A new case was reported today in a MS patient in the U.S. previously treated with beta-interferons and Copaxone. The patient had received 14 infusions of Tysabri alone. This represents the sixth person on Tysabri to develop PML.
