Mark (to Everyone): 7:15 PM: Abi blocks steroid production. Won’t levels still be zero with monotherapy?

Len Sierra (to Everyone): 7:17 PM: Mark, there was a trial showing that Abi alone was just as effective in suppressing T-levels as Abi + Lupron.

Mark (to Organizer(s) Only): 7:34 PM: The abstract did not show a lower dose, just ok for light snack.

Len Sierra (to Everyone): 7:41 PM: From Allen Edel: About 90-95% of metastatic men express at least some PSMA on their prostate cancer cells. Less aggressive PCa produces much less PSMA.
