I wonder how much Pinnacle paid to have an off-label PDT case done live today at the NYSGE meeting? It was probably another one of those situations where Brad said, "do this case and we'll give you $30k, if you don't, well, we can only support your next upcoming meeting with $5k."
All the Feds have to do is either subpoena all e-mail communication from Pinnacle Biologics to Cornell GI Dept or subpoena all e-mail received by Dr. K from Pinnacle Biologics. It's that easy.
