    Efficacy and safety of trastuzumab deruxtecan (T-DXd) in patients (pts) with solid tumors harboring specific HER2-activating mutations (HER2m): Primary results from the international phase II DESTINY-PanTumor01 (DPT-01) study (ESMO 2023)
    In heavily pretreated pts with limited Tx options, T-DXd demonstrated encouraging anticancer activity and long DoR across multiple tumor types with HER2m and a range of HER2 expression levels, with a known safety profile. Translational research will help characterize pts who may derive greatest benefit from T-DXd.

    JIN-A04, highly effective tyrosine kinase inhibitor targeting HER2 exon 20 insertion mutations in NSCLC (AACR 2023)
    It was superior to Mobocertinib (IC50 = 27.1 nM for YVMA and IC50 = 3.3 nM for GSP) and comparable with Poziotinib (IC50 = 3.4 nM for YVMA and IC50 = 0.4 nM for GSP). JIN-A04 is highly potent against HER2 exon 20 insertion mutations including YVMA and GSP, while largely sparing HER2 WT activity. Also, JIN-A04 demonstrated effective HER2 pathway inhibition. Based on these robust activities for HER2 exon 20 insertion, JIN-A04 is expected to provide a potent therapeutic opportunity for NSCLC patients with HER2 exon20 insertion mutations.
