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).
Dor Abelman, BS, of the University of Toronto, reviews results of a comparison of two minimally invasive measurable residual disease (MRD) assays—BM-informed cfDNA whole-genome sequencing (cfWGS) and plasma proteomic MRD (EasyM)—in patients with multiple myeloma (Abstract 7546).
Rami Manochakian, MD, FASCO, of Mayo Clinic Florida, summarizes an educational session at ASCO that reviewed the state of the field of small cell lung cancer (SCLC) treatment. After decades of limited treatment progress, advances are being seen in immunotherapies, radiation therapy, bispecific T-cell engagers, antibody-drug conjugates, and radionuclide therapies.

Shubham Pant, MD, MBBS, of The University of Texas MD Anderson Cancer Center, discusses the practice-changing results of the phase III RASolute 302 study, which showed that daraxonrasib doubled median overall survival compared with standard chemotherapy in pretreated metastatic pancreatic cancer (Abstract LBA5).
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).

Jennifer J. Knox, MD, FRCPC, of Princess Margaret Cancer Centre, provides expert commentary on a phase III study of daraxonrasib vs chemotherapy in previously treated metastatic pancreatic cancer (Abstract LBA5).
