Furthermore they will have a late-cycle meeting on or before November 1. ("For applications that will be discussed at an Advisory Committee meeting, the late-cycle meeting will occur not less than 12 calendar days before the date of the AC meeting. … The background package for the late-cycle meeting should be sent to the applicant not less than 20 days before the meeting if an AC is to be held")

I think you presented a pretty reasonable timetable, however, I would like to argue that I think the late-cycle meeting has already occurred, which is when an AdCom was decided.

For applications that will be discussed at an Advisory Committee meeting, the late-cycle meeting will occur not less than 12 calendar days before the date of the AC meeting. For applications that will not be discussed at an AC meeting, the late-cycle meeting will generally occur not later than 3 months (standard review) or 2 months (priority review) prior to the PDUFA V goal date.

It is my hypothesis that the FDA was working on a No-AdCom timetable. This means that the late-cycle meeting would have occurred somewhere around July 28, at which time if they decided to hold an AdCom, it would explain why Amarin was notified of an AdCom on August 8.

As I mentioned in a previous post, I have a suspicion that the citizen petitions filed by MRC are coming into play because they were filed in early July. Their submission would have fallen between the mid-cycle and late-cycle meeting.

The mid-cycle meeting is held by month 5 for Program and standard reviews(month 3 for priority reviews). The mid-cycle meeting provides an opportunity for management to review the work of the review team thus far in the review cycle.

Therefore, if the petitions brought up a concern the FDA thought was worth addressing, it would have been discussed during the late-cycle meeting. There are a lot of references to work through in all three petitions, so if someone has a summary already prepared, I am all ears.
