Went to a pharmacy dinner for Ingrezza once - mostly because I wanted to go to the restaurant the dinner was hosted at - and the initial approval studies should a very unimpressive response. Yes, improvement in AIMS was statistically significant, but the magnitude was negligible. Even on the package insert, the clinical data is... lacking - the mean change in AIMS score is about -2 and about -3 for the 80 mg dose. Of course, at the dinner I attended the presenter showed these amazing pre/post videos of supposed patients where the AIMS seemed to go from 28 to 0.
Whatever the cost is now, anything about about tree fiddy is too much IMO.
