GenSci139: A highly differentiated and potential best-in-class EGFRxHER2 bispecific ADC, in multiple solid tumors (ESMO 2025) - "Background ENHERTU®, a HER2-targeting ADC, has been approved for the treatment in multiple indications, yet significant unmet needs persist in HER2-low settings beyond breast cancer. These results position GenSci139 as a promising therapeutic candidate for further clinical development in NSCLC, GC, TNBC and other EGFR/HER2-driven malignancies. Legal entity responsible for the study GeneScience Pharmaceutical Co., Ltd."
