Clinical Trial Summary

The purpose of this first-in-human, open-label, multicenter, non-randomized study is to investigate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary clinical activity of ES002023 in patients with advanced solid tumors that are relapsed or refractory to standard therapies.


Clinical Trial Description

ES002023 is a recombinant humanized IgG1 monoclonal antibody (mAb) that specifically targets the human ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1, CD39, UniprotKB: P49961). ES002023 is generated using classic hybridoma technology with an attenuated effector domain (Fc) based on human IgG1. ES002023 binding to CD39 inhibits the enzyme activity of ectonucleoside triphosphate diphosphohydrolase, which can result in the stabilization of pro-inflammatory extracellular ATP (eATP) and the restoration of antitumor immunity by impairing the accumulation of immune suppressive adenosine within the tumor microenvironment. ;
