An old high school acquaintance posted this today:

"Therapy infusion of Lutetium 177 today - time to fry those tumors!"

I've sent him info on Leronlimab twice and asked him to talk to his doctor about it but he didn't seem interested in doing so.
He did mention that his current treatment with the above was part of a clinical trial that ended last November, but the company has continued to supply him with the drug.
