Mechanism of action

Adenosine A2A receptor antagonism reduces the immunosuppressive effects of adenosine on T cells and natural killer cells, thereby enhancing anti-tumor immune responses. This mechanism is intended to work synergistically with checkpoint inhibitors or as a monotherapy to reinvigorate anti-tumor immunity in the tumor microenvironment.
