Then move past hypotheticals and use real numbers.
The majority of the payments to Advent were for one-time expenses for ten key one-time milestones for pre-requisites and preparations for the MAA application for product approval
No, that's just the majority of the R&D payments. The big ticket item is under manufacturing.
The Specials MFG cost for 2023 was $14.9M. See page F28 of the 2023 10K.
There is also the cost of GMP facility that is under Advent's long term sublease. That is probably a total of $10M or so over the years since Advent has had the lease. And do not forget that NWBO spent $10M+ fixing up that space before subleasing it at a price barely over shell facility space.
The worst though is that there is no contract in place for actual commercial manufacturing. If this does get approved LP will have to sit down with LP and get a deal done. I am sure she would negotiate a good deal. For somebody.
