FDA approved AstraZeneca and Daiichi Sankyo’s Enhertu (trastuzumab deruxtecan) for the treatment of adult patients with unresectable or metastatic hormone receptor-positive, HER2-low (IHC 1+ or IHC 2+/ISH-) or HER2-ultralow (IHC 0 with membrane staining) breast cancer, as determined by the FDA approved test, that has progressed on one or more endocrine therapies in the metastatic setting.
Further positive results from the phase III SERENA-6 trial showed camizestrant plus a cyclin-dependent kinase 4/6 inhibitor—palbociclib, ribociclib or abemaciclib—maintained its progression-free survival benefit with longer follow-up and delivered a statistically significant and clinically meaningful improvement in second progression-free survival, demonstrating sustained benefit beyond initial treatment.
