Caveat emptor ... 9720141022

Biogen reported the first case of progressive multifocal leukoencephalopathy (PML) in a Tecfidera patient, who had been part of a clinical trial and was taking the drug for 4-1/2 years.

The patient, who died of pneumonia, had been suffering severe lymphopenia, a low white blood cell condition, for more than three years, which Biogen said was a risk factor for developing PML.

Biogen, which has notified health regulators of the PML case, said 100,000 patients have taken Tecfidera.

The woman took part in the approval study in germany. They let her walk around with severe lymphopenia for more than 3 years!
There were no other risk factors as explanation for the PML.
So it looks like if Tecfidera is the only reason for this unnecessary case of death.
Biogen had admitted that lymphopenia is a known risk für PML long ago (-> fumaderm) . But no warnings in the package insert and for doctors!
