It's always possible the data is bad. To say otherwise is irresponsible because nobody except the researchers have any clue what the outcome will be. At best we can only speculate. I am hopeful the data will be positive but I have zero faith in Dr. Missling to be honest and I wonder if all his past reporting has been cherry picking from limited N size trials.
I understand delays sometimes happen but he seemed adamant that data would be reported by the end of the quarter, and he's repeatedly missed the mark with his estimates.
