François-Clément Bidard, MD, PhD, on Advanced Breast Cancer With Emergent ESR1 Mutations: First-Line Option
ASCO 2026
François-Clément Bidard, MD, PhD, of Institut Curie, presents final progression-free survival 2 findings from the phase III SERENA-6 trial, which investigated the efficacy of camizestrant, a selective estrogen receptor degrader (SERD), vs continued aromatase inhibition in patients with advanced breast cancer with emergent ESR1 mutations. Earlier reports from the trial showed improved progression-free survival with the SERD (Abstract LBA1007).
Laura Alder, MD, of Duke University Medical Center, highlights emerging data discussed in the meeting’s oral abstract session on small cell lung cancer, including increased toxicity without efficacy benefit from concurrent chemoradiation and immunotherapy, the intracranial activity of tarlatamab-dlle, and early data for a SEZ6-targeting antibody-drug conjugate.

Elena Elimova, MD, Princess Margaret Cancer Centre, discusses the efficacy in PD-L1 subgroups of zanidatamab plus chemotherapy with or without tislelizumab as a first-line regimen for HER2-positive locally advanced or metastatic gastroesophageal adenocarcinoma (Abstract 4010).
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).

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.
