Then what was your point here? "he has a history of leaving BEFORE companies do phase 3 Trials even on very successful drugs."
"My best guess is a health issue." Maybe. How much of his "history of leaving BEFORE companies do phase 3 Trials" do you think that might explain?
I don't know why he left. He left without notice. If he DID give notice then why the delay described in the press release? "The Company will begin interviewing new candidates for the position of Chief Medical Officer in January."
