Subgroup Analysis of Patients With No Prior Chemotherapy in EMERALD Trial

Among chemotherapy-naive patients, elacestrant extended median progression-free survival compared with standard therapy, particularly in ESR1-mutated cases.

Episodes in this series

A focused analysis of chemotherapy-naive patients revealed elacestrant’s superior efficacy, demonstrating a median PFS of 3.7 months vs 2.0 months for standard of care in all patients. Among those with ESR1-mutated tumors, elacestrant extended median progression-free survival to 5.3 months vs 1.9 months for standard of care. These findings highlight elacestrant’s particular benefit in patients who have not yet received chemotherapy.
