Key clinical point: Elacestrant significantly improved progression-free survival (PFS) compared with standard-of-care (SOC) endocrine monotherapy in previously treated patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2−) metastatic breast cancer (BC) with a manageable safety.
Major finding: Elacestrant vs. SOC prolonged PFS in the overall cohort (hazard ratio [HR] 0.70; P = .002) and in patients with estrogen receptor 1 mutation (HR 0.55; P = .0005). Grade 3/4 adverse events occurred in 27.0% vs. 20.5% of patients receiving elacestrant vs. SOC therapy, respectively.
Study details: Findings are from the phase 3 EMERALD study including 477 patients with ER+/HER2− metastatic BC who progressed after the first- or second-line treatment with endocrine therapy + cyclin-dependent kinase 4/6 inhibitor and ≤1 rounds of chemotherapy treatment and were randomly assigned to receive elacestrant or SOC endocrine monotherapy.
