"Even if NWBO is sure that L works they can't in all practicality end early due to concerns about reimbursement rates, potential competition and the need for data separation between arms in a long tail. Doc"
Wrong. You get AA first. That allows OS to mature if even necessary, and final pricing to wait. No one is going to crossover if the PFS is released today, imho. PFS maturity is not in a nursing home, it is instead in cryogenic storage by now.
Why on earth are you and other longs wanting trial extensions, when Dr. Bosch nor anyone else mentioned anything about it? Why, what on earth do you know? Why? Good luck to all longs.
