THE HER2-DIRECTED ANTIBODY-DRUG CONJUGATE DHES0815A IN ADVANCED AND/OR METASTATIC BREAST CANCER: PRECLINICAL CHARACTERIZATION AND PHASE 1 TRIAL RESULTS

The HER2-directed antibody-drug conjugate DHES0815A in advanced and/or metastatic breast cancer: preclinical characterization and phase 1 trial results

Abstract Approved antibody-drug conjugates (ADCs) for HER2-positive breast cancer include trastuzumab emtansine and trastuzumab deruxtecan.To develop a differentiated HER2 ADC, we chose an antibody that does not compete with trastuzumab or pertuzumab for binding, conjugated to a reduced potency PBD (pyrrolobenzodiazepine) dimer payload.PBDs are pot
