Zongertinib is a kinase inhibitor of human epidermal growth factor receptor 2 (HER2). In vitro, zongertinib inhibited phosphorylation of HER2, downstream signaling of HER2 (phosphorylation of ERK), and proliferation of lung cancer cells harboring HER2 tyrosine kinase domain activating mutations. In vivo, zongertinib demonstrated anti-tumor activity in mouse xenograft models of NSCLC harboring HER2 tyrosine kinase domain activating mutations. |
