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).

Danny Rischin, MD, of Peter MacCallum Cancer Centre, talks about data from the disease-free survival analyses of the C-POST study, which were conducted per high-risk criteria and start time after radiotherapy. C-POST evaluated adjuvant cemiplimab-rwlc for patients with high-risk cutaneous squamous cell carcinoma (CSCC) (Abstract 6083).

Shilpa Gupta, MD, of Taussig Cancer Institute, discusses findings from the phase III MAIN-CAV study (Alliance A032001) of maintenance cabozantinib and avelumab vs avelumab after first-line platinum-based chemotherapy in patients with locally advanced/metastatic urothelial cancer (Abstract 4514).

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.

Erika P. Hamilton, MD, FASCO, of Sarah Cannon Research Institute, talks about a comparison of the efficacy and safety of tucatinib vs placebo combined with trastuzumab and pertuzumab as maintenance therapy for HER2-positive metastatic breast cancer by stratified subgroups (Abstract 1005).

Thomas A. Jandl, MD, PhD, of Stony Brook University Hospital, discusses data from part 1B of the OLYMPIA-3 trial, which showed that among patients with diffuse large B-cell lymphoma (DLBCL), the safety profile of the first-line combination of odronextamab and CHOP chemotherapy was generally manageable and preliminary efficacy was encouraging, with no meaningful differences between regimens. Additionally, combination with odronextamab did not impact the delivery of CHOP (Abstract 7009).
