Elan Sued Over Tysabri Death

Jul 31, 2005 | Irish Independent

A suit has been filed in a Massachusetts court against Elan and its Tysabri partner, Biogen, on behalf of the family of Anita Smith.

Mrs Smith died of PML, a fatal disorder of the nervous system, when taking Tysabri in combination with Avonex, another MS drug made by Biogen.

The suit alleges that before Tysabri was approved, both Elan and Biogen were aware that the drug's use in combination with Avonex was dangerous, as the FDA's review of Tysabri's biologic licence application stated that Avonex alters the pharmacokinetics of Tysabri.
