Targeting HER2 gene amplification is one of the greatest successes in oncology, resulting in the use of awide array of HER2-directed agents in the clinic. The discovery of HER2-activating mutations as novel therapeutictargets in breast and other cancers marked a significant advance in the field, which led to the metastatic breast andother solid tumor trials MutHER (NCT01670877), SUMMIT (NCT01953926), and one arm of plasmaMATCH(NCT03182634). These trials reported initial clinical benefit followed by eventual relapse ascribed to eitherprimary or acquired resistance. These resistance mechanisms are mediated by additional secondary genomicalterations within HER2 itself and via hyperactivation of oncogenic signaling within the downstream signaling axis.展开更多
