Elizabeth Smyth, MD, on Gastric/GEJ Cancer: Novel CLDN18.2-Targeting ADC
ESMO Congress 2026
Elizabeth Smyth, MD, of Oxford NIHR Biomedical Research Centre, Churchill Hospital, reviews results from the phase III G-HOPE-001 trial, which evaluated the CLDN18.2-targeted antibody-drug conjugate arcotatug tavatecan in previously treated patients with gastric or gastroesophageal junction (GEJ) cancer. Dr. Smyth was a co-chair of the proffered paper session that featured the abstract (Abstract LBA77).
Elizabeth Smyth, MD, of Oxford NIHR Biomedical Research Centre, Churchill Hospital, discusses data from the phase III KEYNOTE-975 study, which examined definitive chemoradiotherapy with or without pembrolizumab in patients with previously untreated locally advanced unresectable esophageal and gastroesophageal junction (GEJ) cancer. Dr. Smyth was a co-chair of the proffered paper session that featured the abstract (Abstract 2875O).
Shannon N. Westin, MD, of The University of Texas MD Anderson Cancer Center, reviews interim overall survival and safety results from a randomized phase III study evaluating durvalumab plus carboplatin/paclitaxel followed by durvalumab with or without olaparib in patients with advanced/recurrent endometrial cancer (Abstract LBA37).
The phase III HARMONi-GI1 trial is evaluating the efficacy and safety of ivonescimab, a PD-1/VEGF bispecific antibody, plus chemotherapy vs durvalumab plus chemotherapy as first-line treatment for advanced biliary tract cancer. At the ESMO Congress 2026, invited discussant James J. Harding, MD, reviewed the results from the preplanned interim analysis (Abstract LBA8).
Brian M. Slomovitz, MD, of Mount Sinai Medical Center, discusses results from a phase III, randomized, open-label study of first-line pembrolizumab vs carboplatin/paclitaxel in patients with mismatch repair–deficient (dMMR) advanced or recurrent endometrial carcinoma (Abstract LBA12).
Sanjiv S. Gangaram-Panday, PhD, of Erasmus University, presents 5-year outcomes from the Surgery As Needed for Oesophageal Cancer (SANO) trial. The study previously demonstrated that active surveillance is noninferior to standard surgery in terms of 2-year overall survival in patients with a complete clinical response after neoadjuvant chemoradiotherapy; active surveillance also resulted in improved quality of life (Abstract LBA78).
