HS-20089 Combination Treatment in Subjects With Advanced Solid Tumors

Recruiting now · Phase 1

Conditions studied: Advanced Solid Tumors

In brief

HS-20089 is an investigational antibody-drug conjugate (ADC) composed of a humanized IgG1 anti-B7-H4 monoclonal antibody conjugated to the topoisomerase I inhibitor payload via a protease-cleavable linker, with an average drug-to-antibody ratio of about 6. This is a phase Ⅰ, open-label, multi-center study to evaluate the safety, tolerability, pharmacokinetics (PK) and efficacy of HS-20089 in combination with other antitumor agents (Adebrelimab with or without platinum; Bevacizumab with or without platinum) in subjects with advanced solid tumors.
