AI Technical Summary
Current therapeutic modalities for advanced cancer, including radiation therapy and conventional chemotherapy, often fail to effectively treat cancers with overexpressed B7-H4, leading to poor prognosis and the need for new therapeutic agents that target B7-H4's biological activity.
Administration of a B7-H4-targeting antibody-drug conjugate (XMT-1660) specifically binding to the extracellular region of B7-H4, conjugated with a fully synthetic macromolecular linker-payload containing auristatin F-hydroxypropylamide, delivered intravenously at varying doses and frequencies.
The B7-H4-targeting antibody-drug conjugate demonstrates antitumor efficacy in preclinical models of endometrial and ovarian cancers, offering a potential therapeutic option for B7-H4-positive cancers that have progressed despite standard treatments.
