vimantoo, you are missing your own point here. We were not talking about the PD-1/PD-L1. We were talking about 10+ PS receptor drugs to COMBINE with PD-1/PD-L1 vesus PS target (Bavituximab) one drug to combine with PD-1/PD-L1.
So your reply is besides the point because I never said the PD-1/PD-L1 doesn't work. BMY/Merck and others proved otherwise.
Peregrine Pharmaceuticals the Microsoft of Biotechnology! All In My Opinion. I am not advising anything, nor accusing anyone.
