Biogen has admitted that she had PML, by way of a 8-K form already:

Even if it is ultimately IRIS that killed her, that doesn't make things any prettier. PML, IRIS . . . they are BOTH wicked "side-effects", and that would just mean that Tysabri caused a double-whammy for her.

Biogen's spokespeople have also announced her death in many articles:

Form 8-K "is the current report companies must file with the SEC to announce major events that shareholders should know about." Shareholders already know this lady had PML, so there may be no further obligation to file with the Securities and Exchange Commission (SEC) when a person dies from a previously reported medically induced disease.
