Opdivo and Opdualag block so-called checkpoint proteins that hold T cells from recognizing and preventing tumors.

Merck is within the hunt with favezelimab, which it’s testing together with its accredited PD-1 blocking blockbuster drug, Keytruda, as a remedy for colorectal most cancers. In the meantime, Immutep is evaluating its LAG-3 inhibitor, eftilagimod alpha, in a number of several types of most cancers together with a head and neck squamous cell carcinoma examine that’s testing the drug together with Keytruda.
