When? I tend to think this type of shit happens in American healthcare all the time. It is the norm. Until average voters stop being manipulated by politicians/ideology and start voting based on issues, it will continue.
Nvcr will continue selling to unsuspecting vulnerable patients until another product, hopefully DCVax-L/Direct, displaces it. Even then NVCR management will still be trying to hype its products.
This type of BS is a good part of the reason why LP/NWBO let the trial run so long.
