Patrick Hwu: How is the combination of anti-LAG-3 and anti-PD1 working mechanistically?

Patrick Hwu shared on X:

“Science Sunday!

The combination of anti-LAG-3 and anti-PD1 antibodies is U.S. FDA approved for patients with advanced melanoma.

But how is this combination working mechanistically?

In a recent issue of Cell 3 manuscripts shed light and suggest that PD-1 blockade enhances T-cell proliferation while LAG-3 blockade enhances anti-tumor effector functions including cytotoxicity, cytokine production, and expression of activating NK receptors.

These insights may lead to the optimization of future therapeutic combinations for patients.

Here are links to the 3 articles as well as an excellent overview:

Article 1, Article 2, Article 3.”
