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).
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).
Douglas B. Johnson, MD, of Vanderbilt University Medical Center, discusses three important melanoma abstracts: the need for more than two doses of nivolumab plus ipilimumab in combination immunotherapy; antitumor activity for low-dose ipilimumab with pembrolizumab after disease progression on PD-1 antibodies; and ipilimumab alone or in combination with anti–PD-1 therapy for metastatic disease resistant to PD-1 monotherapy (Abstracts 10003, 10004, and 10005).
Andres Poveda, MD, of Initia Oncology, discusses phase III results from the SOLO2 trial, which showed that, compared with placebo, maintenance olaparib improved median overall survival by 12.9 months in patients with platinum-sensitive, relapsed ovarian cancer and a BRCA mutation (Abstract 6002).
Thierry André, MD, of Hôpital Saint-Antoine, discusses the phase III results from KEYNOTE-177, which showed that, compared with standard chemotherapy of FOLFOX or FOLFIRI, pembrolizumab doubled median progression-free survival, from 8.2 months to 16.5 months, in patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract LBA4).
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).
