Second, I very much doubt a buy-out is in the works. a. They just raised money to be more than comfortable to get past the postponed PDUFA date. The FDA requested data doesn't seem to have been anything untoward, but will require more time for review. b. PDUFA coming up in 4.5 months with a relatively simple go-to-market strategy and it seems payers and co-pay system are already on board.
Thus it would make no sense at all to sell-out before at least brining in revenue over the course of at least 1-2 years on the market. Assuming all goes well that is.
