Sorry to be unclear...I don't mean to imply that NVS is being shady or shoddy in their development. But a lesson for our "mistakes to avoid" guide would have to be that one should be wary of companies claiming that their drug is so special and so different from everyone else that they don't have to play by the same rules of development.
I can see why NVS would report different safety metrics perhaps, but I can't think of why viral load metrics ought to be different.
