Sara A. Hurvitz, MD, on Breast Cancer: Four Major Studies on Trastuzumab, Pertuzumab, Anthracyclines, and Chemotherapy De-escalation
ASCO20 Virtual Scientific Program
Sara A. Hurvitz, MD, of UCLA’s David Geffen School of Medicine, summarizes four breast cancer studies: KATHERINE, on adjuvant trastuzumab vs trastuzumab in patients with residual invasive disease after neoadjuvant therapy for HER2-positive breast cancer; KAITLIN, on trastuzumab emtansine and pertuzumab vs trastuzumab, pertuzumab, and taxane after anthracyclines as adjuvant therapy for high-risk HER2-positive early breast cancer; TRAIN-2, on neoadjuvant chemotherapy with or without anthracyclines for HER2-positive disease; and PHERGain, on chemotherapy de-escalation using an FDG-PET/CT and pathologic response–adapted strategy in HER2-positive early breast cancer (Abstracts 500, 501, 502, and 503).

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).

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).

Sarah A. Holstein, MD, PhD, of the University of Nebraska Medical Center, discusses top myeloma abstracts from the ASCO20 Virtual Scientific Program: the ENDURANCE trial on carfilzomib, lenalidomide, dexamethasone, and bortezomib; the STaMINA study on transplantation strategies; a first-in-human study on the novel CELMoD agent CC-92480 plus dexamethasone; the CARTITUDE-1 trial on CAR T-cell therapy; and a phase I study of teclistamab (Abstracts LBA3, 8506, 8500, 8505, and 100).

Scott Kopetz, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses phase III results of the BEACON CRC study, which confirmed that, compared with standard chemotherapy, encorafenib plus cetuximab with or without binimetinib improved overall survival and objective response rate in previously treated patients with BRAF V600E–mutated metastatic colorectal cancer (Abstract 4001).

Jeffrey A. Meyerhardt, MD, MPH, of Dana-Farber Cancer Institute, discusses results from the CALGB/SWOG 80702 trial of celecoxib plus standard adjuvant therapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX). Adding celecoxib to standard chemotherapy did not significantly improve disease-free or overall survival (Abstract 4003).
