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).

Bjorn Henning Gronberg, MD, PhD, of St. Olav’s Hospital, discusses findings from a phase III trial of concurrent thoracic radiotherapy (TRT) plus platinum/etoposide chemotherapy and the PD-L1 inhibitor durvalumab in patients with extensive-stage small cell lung cancer (SCLC) (Abstract LBA8005).
Suneel Kamath, MD, of Cleveland Clinic, discusses a study that found tissue tumor mutation burden (TMB) was a stronger predictor of immunotherapy outcomes than blood-based circulating tumor DNA testing, with high tissue TMB associated with a longer time to treatment failure (Abstract 2580).

Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, presents data from the phase III ADAM trial, a multicenter, randomized, double-blinded, placebo-controlled study of the anti–PD-L1 antibody avelumab in patients with Merkel cell carcinoma and lymph node metastases (Abstract LBA9504).

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).

Turner, MD, PhD, of the Royal Marsden Hospital, Institute of Cancer Research, discusses results from the primary analysis of the persevERA BC trial, which investigated giredestrant plus palbociclib vs letrozole plus palbociclib as first-line therapy in patients with estrogen receptor (ER)-positive, HER2-negative locally advanced or metastatic breast cancer (Abstract LBA1006).
