ARTEMIS-006: A Phase 2 Study to Evaluate Efficacy and Safety of Intravenous Administration of HS-20093 in Patients With Head and Neck Squamous Cell Carcinoma and Other Solid Tumors

HS-20093-205

HS-20093 is a fully humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. This is a phase 2, open-label, multi-center study to evaluate the efficacy, safety, pharmacokinetics (PK) and immunogenicity of HS-20093 as a monotherapy in patients with head and neck squamous cell carcinoma and other solid tumors.
