I think it should be CTLA. Although I have seen a few places say CLTA. Let us go with the former. It is Tecentriq. It is interesting that you mention Roche and pela and CTLA. I guess one could also mention BMS. And others. I wonder if Dr. Allison, the developer and his ONC Scientific Advising Spouse discuss it.
There are still a lot of avenues for pelareorep.
A precipitous drop like we have seen is not pleasant. I think the writing has actually be on the wall for some time. BAD JUJU I AM AFRAID.
Maybe that can be changed.
