Shutting down a gene called PRMT5 stopped metastatic estrogen receptor-positive breast cancer cells from growing after they acquired resistance to a standard therapy known as CDK4/6 inhibitors, UT Southwestern Medical Center researchers showed in a new study.
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.
