    Overcoming ADC Resistance: Construction and Preclinical Applications of Enhertu-Resistant Models

    Antibody-drug conjugates (ADCs), particularly the HER2-targeting Enhertu (DS-8201), have revolutionized targeted cancer therapy. Despite their clinical success, drug resistance remains a major hurdle limiting long-term therapeutic benefits. To address this challenge, GemPharmatech has developed multiple ADC resistance models, including a HER2-positive JIMT-1 breast cancer xenograft (CDX) model with acquired resistance to Enhertu, and a primary Enhertu-resistant HER2-positive lung cancer model from our patient-derived xenograft (PDX) library. Join us to explore how these Enhertu-resistant models serve as translational tools to elucidate resistance mechanisms and evaluate novel therapeutic strategies.
