About ES002:

ES002 is a highly promising, potential best-in-class anti-CD39 antibody designed to promote anti-tumor immunity. CD39 is a key enzyme regulating the production of adenosine, a critical immune suppressor. By blocking CD39 function, ES002 also stabilizes pro-inflammatory extracellular ATP (eATP) and restores anti-tumor immunity within the tumor microenvironment. ES002 demonstrated highly potent single-agent anti-tumor activity in in vivo pharmacology studies.
