Yes, I can well imagine that there were certain hints from their internal studies that pointed to PFS (of course not in its full scope, as thats hard to imagine/understand as a non sufferer). However thats far from what many people here imagine: Conclusive, obvious, proof/information on the full scope of the devastating impacts of PFS like they experience it. Information that no one could overlook or reasonably explain away. And information that it affected a large number/significant percentage of people.
If that was the case they would have won the case! No such proof was submitted to the court. It is a very muddy picture precisely because so few are affected, so that its easily ignored even by US when we took the damn drug with updated labels (in many forums members cases).
