How can you possibly know this? The "Action" letter is due today from FDA - prior to the expiry of the PDUFA time limit. The letter will be transmitted by fax probably to Pozen some time before the end of business or even after busainess hours today (5:00 pm or later) Washington DC time. Pozen will probably announce the news tonight or prior to market opening on 8/2/07.
Trexima will be approved. Buy it now because tomorrow it will probably be in the mid-20s.
