Samuel J. Klempner, MD, FASCO, on Advanced HER2-Negative Gastroesophageal Cancer: Ivonescimab Plus FOLFOX
ASCO 2026
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.

Sara A. Hurvitz, MD, FACP, of Fred Hutchinson Cancer Center, provides an update focusing on progression-free survival after next line of treatment and subsequent therapies among patients enrolled in the ASCENT-03 trial. The study compared sacituzumab govitecan vs chemotherapy in patients with previously untreated metastatic triple-negative breast cancer (Abstract 1001).

Yelena Y. Janjigian, MD, FASCO, of Memorial Sloan Kettering Cancer Center, discusses safety results for DESTINY-Gastric03 Part 2 (arms D and F) and Part 4. The trial evaluated first-line fam-trastuzumab deruxtecan-nxki–based regimens in advanced HER2-expressing gastric cancer, gastroesophageal adenocarcinoma, and esophageal carcinoma (Abstract 4002).

Alicia K. Morgans, MD, FASCO, of Dana-Farber Cancer Institute, discusses data from the phase II ARACOG (AFT-47) randomized clinical trial, which compared the two androgen receptor pathway inhibitors’ effects on cognitive function in patients with advanced prostate cancer (Abstract 5005).
Paolo Tarantino, MD, PhD, of Dana-Farber Cancer Institute, reviews the results of a large clinicogenomic database study that looked at overall survival by genomic profile among patients with HER2-positive metastatic breast cancer. Patients with mutations in key DNA repair genes experienced a numerically worse prognosis, representing an unmet need for drug development, say researchers (Abstract 1045).
