Day 74 letter is FDA acceptance letter of ANCHOR sNDA.
AMRN management said during some presentation that the letter was very clean (= no issues raised by FDA). Cleaner than the MARINE 74 day letter. So obviously management was so confident about a cakewalk AdCom.
Had FDA raised the concerns in the 74 day Letter or anywhere before AdCom, we would not have seen this tragedy with PPS. Anyway i am adding here as this now is potentially a 10x stock in 2-3 years. What a deal!
