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).
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).
Mansoor Raza Mirza, MD, of Copenhagen University Hospital, discusses phase II study results that showed the combination of palbociclib and letrozole, compared with placebo plus letrozole, improved progression-free survival in patients with estrogen receptor–positive advanced or recurrent endometrial cancer (Abstract LBA28).
Alexander M. Eggermont, MD, PhD, of the Princess Maxima Center for Pediatric Oncology, discusses final results of the phase III EORTC 1325-MG/Keynote 054 trial, which confirmed a sustained recurrence-free survival benefit of pembrolizumab vs placebo in patients with resected high-risk stage III melanoma, as well as a decrease in the incidence of distant and locoregional recurrence (Abstract LBA46).
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).
