PD-L1 crosslinking as a new strategy of 4-1BB agonism immunotherapy

Abstract

4-1BB has been considered a promising target in cancer immunotherapy for decades. Nevertheless, early 4-1BB-targeted agent demonstrated significant liver immuno-toxicity.

A new wave of 4-1BB-based therapy is being developed to circumvent hepatotoxicity with bispecific molecule that directs 4-1BB agonism to the tumor microenvironment by targeting tumor-associated immune checkpoint molecule, PD-L1.
