A study led by researchers from MD Anderson Cancer Center showed a significant overall survival benefit with ribociclib plus endocrine therapy for postmenopausal patients with hormone receptor-positive (HR+) human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer.
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.
