Description
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.
Official Title
An Open-Label, Multicenter, First-in-Human, Dose-Escalation, Phase 1 Study of ES002023 in Patients With Locally Advanced or Metastatic Solid Tumors
Details
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.

within the last two years
13. CNS metastases 14. Active autoimmune disease or documented history of autoimmune disease that required
systemic steroids or other immunosuppressive medications
