I just come to show that the MHRA is not really familiar with companies applying for MIA first and letting the MAA wait. Most biotechs would want to apply for MAA asap. As I said here a few times time now. Its a huge mystery to me why Linda thinks/tries to convince us at the ASM the request for MAA can only be made AFTER the MIA is granted and not "at the same time as the MA application" (June 2022).
You realize, of course, the response you received from MHRA, if true, would make NWBO’s comment, that commercial MIA authorization is a prerequisite for an MAA submission, a fiction.
Here is the relevant part of the response you received.
