"At no point did Nader drop the any day now for first injection and the presentations never changed up until the end of 2nd quarter, Nader really thought the TNBC trial would start and that dr Pestell was making it happen, until he realized it was not."

Bingo! I also believe this is the likely scenario as to what may have led to RP's termination. I don't think the BoD would have fired RP unless there was some level of misrepresentation involved. NP was taking the hits on the missed deadlines while RP was pulling the levers. And as many others have pointed out, look how things are now progressing since RP's removal.
