RE:PP amount?
A particular number doesn't matter. What matters is whatever "x" amount is required to get us to a BTD & a significant step closer to either an AA or traditional approval.
ImmunityBio orchestrated a $310 million royalty financing & equity deal in December 2023 with Oberland Captial, which was for a single indication drug at the pre-BLA approval stage. You could make a strong case that a BTD (pre-NDA approval) for a potentially much more versatile drug is worthy of a sizeable fraction of that...
