"In all likelihood, 9902b will be fully enrolled by the time the FDA makes its decision in the next few weeks."
What are you basing that on Dew? As of March 29 there were 400 patients enrolled and they seem to be enrolling at the rate of 30 per month. So, assuming this rate stays the same, it seems to me that the best we can hope for full enrollment would be the end of June, rather than the May 15 PDUFA date.
Perhaps enbrollment picks up following the positive panel recommendation and in that case your conjecture may be correct. That would really be nice as it eliminates one of the possible headaches on how to complete 9902b enrollment after approval which, based on the recent panic shown by Scher and others, I am now quite sure will occur sooner than May 15 (approval that is!)...
