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).
Stephen R.D. Johnston, MD, PhD, of The Royal Marsden NHS Foundation Trust, discusses phase III study findings from the global monarchE trial, which showed that when added to standard adjuvant endocrine therapy, abemaciclib is the first CDK4/6 inhibitor to improve invasive disease–free survival in hormone receptor–positive high-risk early breast cancer (Abstract LBA5_PR).
Read more on the monarchE trial in the Journal of Clinical Oncology.
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).
Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses the first results from the phase III CheckMate 9ER trial, which suggested the combination of nivolumab and cabozantinib is safe. It showed activity in progression-free and overall survival, as well as in overall response rates and may have a place in treating patients with metastatic renal cell carcinoma (Abstract 696O_PR).
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).
Cécile Le Pechoux, MD, of the Institut Gustave Roussy, discusses new findings from an international trial on an old controversy: What is the role of postoperative radiotherapy in locally advanced (stage III) non–small cell lung cancer? The researchers enrolled patients with completely resected disease and mediastinal N2 involvement (Abstract LBA3).
