Laura Alder, MD, on New Data on Combination Therapy, Immunotherapy, and ADCs in Small Cell Lung Cancer
ASCO 2026
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.

Linda R. Mileshkin, MD, MBBS, FRACP, of Peter MacCallum Cancer Centre, shares results from the phase I/IIA BLUESTAR study on the safety and efficacy of puxitatug samrotecan, a B7-H4–directed topoisomerase I inhibitor antibody-drug conjugate, in patients with endometrial cancer or ovarian cancer (Abstract 5515).

Samuel J. Klempner, MD, FASCO, of Mass General Brigham Cancer Institute, discusses a single-arm phase II study—which is currently open and enrolling (ClinicalTrials.gov identifier NCT07070466)—evaluating ivonescimab in combination with FOLFOX as front-line therapy in locally advanced, unresectable, or metastatic HER2-negative gastroesophageal adenocarcinoma (Abstract TPS4246).

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.
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).
ClinicalTrials.gov identifier: NCT06382948
Walter Weber, MD, of University Hospital Basel, presents data from the international randomized phase III PREPEC trial (OPBC-02), which found prepectoral implant-based breast reconstruction (IBBR) significantly and relevantly improved long-term quality of life—at the cost of a higher risk of loss or replacement of expander or implant—compared to subpectoral IBBR (Abstract 504).
