Yesterday (Friday April 7, 2017) the FDA announced in an updated guidance that it has delayed until May 5, 2018 the requirement for DMF and BPF submissions to be submitted in eCTD format. Other submission types, NDA, ANDA and BLA, must still meet the 5 May 2017 deadline for submission in eCTD format. For those who have already converted their DMF submissions to eCTD format, you are now 1 year ahead!
