Elizabeth Smyth, MD, on New Data in Gastric/Gastroesophageal Cancers
ASCO 2026
Elizabeth Smyth, MD, of Oxford NIHR Biomedical Research Centre, Churchill Hospital, discusses three major studies presented at this year’s meeting: the antibody-drug conjugate izalontamab brengitecan in recurrent or metasatic esophageal squamous cell carcinoma (Abstract 4008); the ATTRACTION-6 study of chemoimmunotherapy in HER2-negative advanced gastric/gastroesophageal junction (GEJ) cancer (Abstract 4006); and an investigational EP4 antagonist in combination with chemoimmunotherapy as a first-line strategy for HER2-negative gastric/GEJ cancer (Abstract 4007).

Mazyar Shadman, MD, of the University of Washington and Fred Hutchinson Cancer Center, describes the safety and efficacy results of the all-oral first-line combination regimen of sonrotoclax and zanubrutinib for patients with treatment-naive chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), as well as the doublet’s effect on measurable residual disease (Abstract 7043). He also discusses the phase III BGB-11417-304/CELESTIAL-TNCLL-2 trial; this ongoing study is evaluating sonrotoclax plus zanubrutinib vs venetoclax and acalabrutinib in treatment-naive patients with chronic lymphocytic leukemia (CLL) (Abstract TPS7099).
Lucy Gilbert, MD, of McGill University Health Centre, discusses subgroup analyses from the ROSELLA study. Relacorilant plus nab-paclitaxel demonstrated a statistically and clinically significant overall survival benefit in patients with platinum-resistant ovarian cancer compared to a weekly taxane; subgroup analyses for overall survival showed a consistent benefit favoring the addition of relacorilant to nab-paclitaxel irrespective of prior taxane use (Abstract 5503).

Xin Gao, MD, of Massachusetts General Hospital and Harvard Medical School, discusses initial results from the phase I EXCEED trial of LY4101174, a Nectin-4–targeting antibody-drug conjugate, for patients with advanced or metastatic urothelial carcinoma (Abstract 4517).

Atish Choudhury, MD, PhD, of Dana-Farber Cancer Institute, talks about findings from the phase II A-DREAM/Alliance A032101 trial, which explored the possibility of androgen-deprivation (ADT) interruption in patients with metastatic hormone-sensitive prostate cancer who had an exceptional response to androgen receptor pathway inhibitors (ARPIs) (Abstract 5004).

Noelle Cloven, MD, of Texas Oncology, discusses the actively recruiting RAINFOL-03 (ENGOT-EN-31/GOG-3128) study, a global, phase III, open-label, randomized study of rinatabart sesutecan vs investigator’s choice of chemotherapy in patients with endometrial cancer after receipt of platinum-based chemotherapy and PD-L1 inhibition (Abstract TPS5646).
