The strange part of his story of the Berger comment (if it happened) is that anyone would be surprised they were working on the NDA. These are supposed to be seasoned biotech investors at a conference like that.
Berger has made some good moves. Restructuring the Merck deal, which had been something of a fiasco and retaining all rights to Ponatinib as it continues to move along and become fully derisked. Jerk or not, he's had a good run over the past few years.
