Antonio Llombart-Cussac, MD, PhD, on ADELA: Elacestrant Plus Everolimus in ESR1-Mutated ER-Positive HER2-Negative Advanced Breast Cancer
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).

Jonathan W. Goldman, MD, of the University of California, Los Angeles, presents event-free survival data from the primary analysis of the phase III LIBRETTO-432 trial, which investigated the efficacy of the kinase inhibitor selpercatinib in patients with stage IB–IIIA RET fusion–positive non–small cell lung cancer (NSCLC) (Abstract LBA3).

Mali Barbi, MD, MS, of Northwell Health Cancer Institute Center for Women's Cancer, discusses durable survival benefits shown in the NRG-GY018 trial with pembrolizumab and the RUBY trial with dostarlimab for patients with mismatch repair–deficient (dMMR) endometrial cancer. In addition, B7-H4 antibody-drug conjugates such as puxitatug samrotecan are emerging as options for relapsed/metastatic disease.

Veronica Diermayr, PhD, of EDDC and A*STAR, discusses the use of artificial intelligence (AI) driven strategy called H&E 2.0 in gastric and esophageal cancer. Researchers tested the feasibility of training deep-learning models on hematoxylin and eosin images of gastroesophageal carcinomas and their ability to predict EBC-129 antigen expression directly from these images. EBC-129 is an experimental antibody-drug conjugate that targets N256-glycosylated CEACAM5/6, which is highly expressed on solid tumors, including gastroesophageal cancers (Abstract 4018).

Kevin Kalinsky, MD, MS, FASCO, of Winship Cancer Institute of Emory University, provides an update focusing on progression-free survival after next line of treatment and subsequent therapies among patients enrolled in the ASCENT-04 trial. The study compared sacituzumab govitecan plus pembrolizumab vs chemotherapy plus pembrolizumab in patients with previously untreated PD-L1–positive metastatic triple-negative breast cancer (Abstract LBA1000).

Jame Abraham, MD, FACP, of Cleveland Clinic, provides an update on the DESTINY-Breast05 trial, which is an ongoing phase III trial investigating postneoadjuvant trastuzumab deruxtecan (T-DXd) as compared with trastuzumab emtansine (T-DM1) in patients with HER2-positive breast cancer with residual invasive disease and node-positive disease at surgery or inoperable disease at diagnosis. Dr. Abraham makes special note of rates of interstitial lung disease seen in the trial and methods of management.
