More on the 4th case of PML in a pwMS on Tecfidera

M
Rumours about a 4th case of PML in a 61 year old MSer have been confirmed. What is not mentioned in the report is whether Tysabri played a role, but I suspect it didn’t given the potential benefit for Biogen’s share price of blaming natalizumab instead of Tecfidera.

    • The webpage link that Anon at 7:43:00pm put states

      "The patient had previously taken natalizumab (Tysabri) for 6 years and 4 months, but the company said that prior exposure wasn't considered a confounder in this case. She'd also taken interferon beta-1a (Avonex) and intravenous immunoglobulin.

      Few other details about the case were made available. Neither Biogen nor the FDA or the European Medicines Agency (EMA) would comment on the case. "
