Patrick Hwu: How does anti-CTLA-4 and anti-PD-1 combination work mechanistically?

Patrick Hwu shared a post on LinkedIn:

“The combination of anti-CTLA-4 and anti-PD-1 antibodies is FDA approved for the treatment of advanced melanoma.

How does this combination work mechanistically?

In a recently published study in Cell by Cell Press using both single cell TCR and RNA sequencing, Wang et al demonstrate that the combination results in higher numbers of clonal T cells capable of recognizing melanoma and that anti-CTLA-4 drives the expansion of exhausted T cells while anti-PD-1 reinvigorates them.

These insights may help with future patient selection as well as enhanced combinations and treatment schedules.”

Combination anti-PD-1 and anti-CTLA-4 therapy generates waves of clonal responses that include progenitor-exhausted CD8⁺ T cells.
