A Phase 2, Open-label, Multi-center Study to Evaluate the Efficacy, Safety, Pharmacokinetics and Immunogenicity of HS-20093 in Patients With Advanced Esophageal Carcinoma and Other Advanced Solid Tumors (ARTEMIS-005)

HS-20093-203

HS-20093 is a humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. The objectives of this study are to investigate the anti-tumor activity, safety, pharmacokinetics and immunogenicity of HS-20093 in Chinese advanced esophageal carcinoma and other solid tumor patients.
