Thierry André, MD, of Hôpital Saint-Antoine, discusses final overall survival data for the phase III KEYNOTE-177 study, which confirmed pembrolizumab as a new standard of care for first-line treatment of patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract 3500).
Evan J. Lipson, MD, of Johns Hopkins University, discusses primary phase III results from the RELATIVITY-047 study, which showed that relatlimab plus nivolumab as a fixed-dose combination may improve progression-free survival compared with nivolumab monotherapy in patients with advanced melanoma. This is the first study to demonstrate a benefit from dual inhibition of the LAG-3 and PD-1 pathways.
Ian Chau, MD, of Royal Marsden NHS Foundation Trust, discusses first results of the CheckMate 648 study, which showed that nivolumab plus chemotherapy and nivolumab plus ipilimumab both demonstrated superior overall survival vs chemotherapy alone in patients with advanced esophageal squamous cell carcinoma. These regimens may represent potential new first-line treatment options (Abstract 4001).
Brian K. Link, MD, of the University of Iowa Carver College of Medicine, reviews three abstracts on state-of-the-art therapies for mantle cell lymphoma: bendamustine, rituximab, lenalidomide and bortezomib; treatment patterns and outcomes for previously untreated patients; and venetoclax, lenalidomide, and rituximab in newly diagnosed disease (Abstracts 7503, 7504, and 7505).
Ann S. LaCasce, MD, of Dana-Farber Cancer Institute, discusses results from the CALGB 50801 Alliance study, which showed that a PET scan–adapted approach may reduce the need for radiation treatment and may improve progression-free outcomes in patients with stage I/II bulky classic Hodgkin lymphoma (Abstract 7507).
Taiga Nishihori, MD, of the H. Lee Moffitt Cancer Center and Research Institute, discusses the outcome of a trial that explored maintenance therapy with ixazomib after allogeneic hematopoietic cell transplantation in patients with high-risk multiple myeloma. Toxicities unrelated to the maintenance treatment forced the trial to close prematurely (Abstract 7003).
