Camizestrant combination delayed time to first progression by 55% and to second progression by 37% in patients with advanced HR-positive breast cancer with an emergent ESR1 mutation in SERENA-6 trial
Switching to camizestrant led to a 99% median reduction in total ctDNA vs. a 64% increase for patients who remained on standard of care. 51% of patients receiving the camizestrant combination achieved total ctDNA clearance vs. 1.9% with standard of care – early total ctDNA clearance was associated with an improvement in long-term outcome.Further positive results from the Phase III SERENA-6 trial showed AstraZeneca's camizestrant plus a cyclin-dependent kinase (CDK) 4/6 inhibitor – palbociclib, ribociclib or abemaciclib – maintained its progression-free survival (PFS) benefit with longer
