The fact that he’s waiting to have it made likely means they received enough from biopsy to make a lysate and/or determine what major antigens distinguish it. Odds on favorite is a personalized therapy.
(To my knowledge Direct is not currently in individual experimental use at UCLA (but who knows?), so it’s probably either L or some other personalized therapy with a combination).
Prayers go out to him and his loved ones. He has an extra complex GBM.
