You may be able to listen to it live - the committe will vote at the conclusion of the meeting. Seldom does the FDA make a decision differently ADCOM. That is why imo it is key to be long going into the meeting if you believe AMRN will get a positive vote instead of waiting for the FDA meeting in December.
I followed the first ARNA AdCom on a chat page where some people in the audience would continuously report the main points of each speaker and then the vote. This means the sessions are not completely closed to the public and we should be able to hear something right away.
