For those who have not yet heard, Biogen filed another 8K this morning about another case of PML. I don't have any confirmed details yet, and will post when I know more.

This is what I have from a neuro:
"I haven't heard anything more about the case than is on the 8K. This patient was monotherapy for 26 months and in the EU. This patient's PML is confirmed using accepted definitions of positive PCR in individual with consistent MRI and history. Clinical vigilance seems to have caught this one early as well. FWIW, the last time I got an update, patient 1 (Sweden) was doing well and at home, Patient 2 (Germany) was still in ICU but able to be extubated and able to communicate some (expect permanent sequelae), Patient 3 (US -Florida?) was discharged and doing well. Haven't yet heard what symptoms this patient had. "
