That's the case alright. It's is the first death since relaunch. Unfortunately, early detection and treatment didn't save her:

"The patient who died was a United States patient who had received 14 monthly infusions of Tysabri as a stand-alone treatment. Previously she had received other therapies.

After developing the brain infection, the patient was treated with a procedure known as plasmapheresis, in which blood is removed, cleared of the drug, and replaced.

While the U.S. patient died, two patients who developed PML in Europe, and whose cases were announced in July, appear to be recovering following treatment, even though one had not been expected to survive. Earlier this month, Biogen announced that a fourth patient had developed PML. This patient, in Europe, is still alive.

The European patient that had not been expected to survive had developed a condition known as immune reconstitution inflammatory syndrome, or IRIS. This occurs when the immune system, in eliminating an infection, produces an excessive inflammatory response that can worsen symptoms.

The patient was treated with corticosteroids.

Geoff Meacham, an analyst at J.P. Morgan, said it seems likely the U.S. patient, having gone through plasmapheresis, died of IRIS, and that since the European patient recovered, it might be possible to manage IRIS using steroids and close monitoring. Biogen declined to confirm this theory, citing patient privacy. "
