Why in the world would you have Transcelerate act as a moderator? What's to moderate?
All I'm stating is that PPHM should bargain from a position of strength. About a half-dozen or so of the BP's can use their wealth as a club only if they can do so.
There are many pharmas that might not be able to match the wealth of the rich ones, but many could come up with an initial partial payment that would see PPHM through the PIII tests.
Once approved, earnings would be there to satisfy whatever balance remains due.
