ASCO 2026
Antonio Llombart-Cussac, MD, PhD, of Medica Scientia Innovation Research (MEDSIR), discusses the ongoing ADELA study, a double-blind, placebo-controlled, randomized phase III trial of elacestrant plus everolimus vs elacestrant plus placebo in patients with estrogen receptor (ER)-positive HER2-negative advanced breast cancer with ESR1-mutated tumors who experienced disease progression on endocrine therapy plus CDK4/6 inhibition (Abstract TPS1154).
