Kevin Kalinsky MD; ASCO 2026: ASCENT-04 Study Finds Sacituzumab Govitecan plus Pembrolizumab Helps Patients with Previously Untreated Metastatic PD-L1 Positive Triple Negative Breast Cancer Live Longer Without Progression Beyond Subsequent Therapies

CHICAGO, USA—Combining the antibody-drug conjugate sacituzumab govitecan with pembrolizumab immunotherapy for patients with metastatic triple-negative breast cancers testing positive for the programmed death-ligand 1 (PD-L1) led to significant delays of disease progression after subsequent therapy in comparison with standard of care using a combination of chemotherapy with pembrolizumab. That’s according to first author of research reported at the 2026 American Association of Clinical Oncology Annual Meeting Kevin Kalinsky MD, Division Director of Breast Medical Oncology from Emory University at the Winship Cancer Institute, Hematology and Medical Oncology, in Atlanta, USA. He told reporter Peter Goodwin more about the details.
