Egbert F. Smit, MD, PhD, of the Netherlands Cancer Institute, discusses interim results from the DESTINY-Lung01 trial of fam-trastuzumab deruxtecan in patients with HER2-mutated metastatic non–small cell lung cancer. The data show clinical activity with high overall response rates and durable responses (Abstract 9504).
Seema A. Khan, MD, MPH, of the Lynn Sage Comprehensive Breast Center, discusses phase III trial results showing that in newly diagnosed metastatic stage IV breast cancer, locoregional treatment of the primary tumor did not offer a greater survival benefit than systemic therapy (Abstract LBA2).
Nancy U. Lin, MD, of Dana-Farber Cancer Institute, discusses the HER2CLIMB study of patients with previously treated HER2-positive metastatic breast cancer that had metastasized to the brain. Adding tucatinib to trastuzumab and capecitabine doubled the intracranial response rate and reduced the risk of death by nearly half, compared with trastuzumab plus capecitabine (Abstract 1005).
Farhad Ravandi-Kashani, MD, of The University of Texas MD Anderson Cancer Center, discusses updates from a phase I dose-escalation study of AMG 330, a bispecific T-cell engager molecule. It showed early evidence of an acceptable safety profile, drug tolerability, and antileukemic activity, supporting further dose escalation in patients with acute myeloid leukemia (Abstract 7508).
David R. Wise, MD, PhD, of New York University Perlmutter Cancer Center, summarizes three important studies in prostate cancer: circulating tumor cell count as a prognostic marker of PSA response and progression in metastatic castration-sensitive disease; new phenotypic subtypes; and how circulating tumor DNA dynamics associate with treatment response and radiologic progression-free survival (Abstracts 5506, 5507, and 5508).
Meletios A. Dimopoulos, MD, of the University of Athens, discusses phase III results from the BOSTON trial, which showed that once-weekly selinexor, bortezomib, and dexamethasone significantly improved progression-free survival and overall response rates compared with twice-weekly bortezomib and dexamethasone in patients previously treated for multiple myeloma (Abstract 8501).
