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).
Parameswaran Hari, MD, of the Medical College of Wisconsin, discusses phase III data from a 6-year follow-up of the STaMINA trial, which compared progression-free survival among 758 patients with high-risk multiple myeloma who received a second autologous transplant and lenalidomide maintenance; consolidation with lenalidomide, bortezomib, and dexamethasone followed by lenalidomide maintenance; or lenalidomide maintenance alone (Abstract 8506).
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).
Peter Reichardt, MD, PhD, of Helios Klinikum Berlin-Buch, discusses the 10-year survival analysis of 3 years vs 1 year of adjuvant imatinib for patients with high-risk gastrointestinal stromal tumor. The study found that about 50% of deaths can be avoided with longer imatinib treatment (Abstract 11503).
Nikhil C. Munshi, MD, of Dana-Farber Cancer Institute, discusses initial results from the KarMMa tria, showing that idecabtagene vicleucel, a B-cell maturation antigen-targeted CAR T-cell therapy, demonstrated deep and durable responses in patients with heavily pretreated relapsed or refractory multiple myeloma. Efficacy and safety data support a favorable clinical benefit-risk profile across the target dose range (Abstract 8503).
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).
