Sorry if this is a medically ignorant question, but do we know if Dr Chan is using a PD-1 inhibitor in conjunction with Leronlimab? The two together turn a cold or lukewarm tumor "hot" so it can be better seen/attacked by the immune system, correct?

And do we also know that he's still on LL? 700 mg dose?

Just wondering what the LL specifics are of his treatment.
