Pasi A. Janne, MD, PhD, of Dana-Farber Cancer Institute, discusses study findings that show patritumab deruxtecan is effective in patients with EGFR-mutated and inhibitor-resistant non–small cell lung cancer. Dr. Janne also explains why targeting HER3, a mutation expressed in most EGFR-altered cancers, is a beneficial treatment approach (Abstract 9007).
Martin Reck, MD, PhD, of LungenClinic, discusses a 2-year update of the CheckMate 9LA study, which sought to determine whether nivolumab plus ipilimumab combined with two cycles of chemotherapy is more effective than four cycles of chemotherapy alone as a first-line treatment for patients with stage IV non–small cell lung cancer (Abstract 9000).
Peter H. O’Donnell, MD, of The University of Chicago, discusses response and survival results from the phase II KEYNOTE-052 study, which showed that after up to 5 years of follow-up, pembrolizumab continued to elicit clinically meaningful, durable antitumor activity in cisplatin-ineligible patients with advanced urothelial cancer (Abstract 4508).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses first phase III results from a prospective high-risk cohort of patients with luminal breast cancer, which showed a good prognosis in some women with more than four positive lymph nodes and low recurrence scores. The study also showed that a lower postendocrine Ki67 index and limited tumor burden may be promising criteria for chemotherapy de-escalation strategies, even in patients with high recurrence scores (Abstract 504).
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).
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.
