Thierry Andre, MD, of Hôpital Saint-Antoine, discusses phase III KEYNOTE-177 findings on the reduced risk of disease progression or death in patients receiving pembrolizumab monotherapy as a first-line treatment of microsatellite instability–high and/or mismatch repair–deficient metastatic colorectal cancer (Abstract 396O).
Erica L. Mayer, MD, MPH, of Dana-Farber Cancer Institute, discusses an initial analysis of phase III findings from the PALLAS trial, which suggested the benefits observed in the metastatic setting with palbociclib plus endocrine therapy did not translate into the earlier adjuvant setting for patients with hormone receptor–positive, HER2-negative breast cancer. Long-term follow-up is ongoing (Abstract LBA12).
Ezra E.W. Cohen, MD, of the University of California, San Diego, discusses primary results of the phase III JAVELIN trial of locally advanced squamous cell carcinoma of the head and neck, in which the immune checkpoint inhibitor avelumab was combined with chemoradiotherapy followed by avelumab maintenance. Although the study results were negative, Dr. Cohen suggests other regimens that may prove to be effective (Abstract 910O).
Benjamin Besse, MD, PhD, of the Gustave Roussy Cancer Centre, discusses results of the phase II PRINCEPS trial, which assessed, for the first time, the effect of just one injection of the immunotherapy atezolizumab before surgery in patients with resectable non–small cell lung cancer (Abstract 1215O).
Erika P. Hamilton, MD, of Sarah Cannon Research Institute, discusses results of the nextMONARCH study, which indicated that combining abemaciclib with tamoxifen improved overall survival. Dr. Hamilton also details adverse events in different arms of the study (Abstract 273O).
David S. Hong, MD, of The University of Texas MD Anderson Cancer Center, discusses study findings on sotorasib, a novel, first-in-class, oral KRASG12C inhibitor. The agent demonstrated durable disease control in heavily pretreated patients with non–small cell lung cancer (Abstract 1257O).
