The hospital has a list of approved drugs. Most cancer doctors don't deviate from what they use. I am at one hospital, and both Cancer doctors use different drugs.

I had a good friend in Houston with Glioblastoma, and we got the paperwork to the doctor to try Leronlimab, and his words were, "It's too late." I would think he probably did not want to fill out the paperwork. Piece of shit!

Sad to say, he did not make it.
