Sumanta K. Pal, MD, of City of Hope, discusses results from a phase II study that sought to determine whether adding berzosertib, a selective ATR inhibitor, to the standard upfront chemotherapy regimen of cisplatin with gemcitabine may improve outcomes in patients with metastatic urothelial carcinoma (Abstract 4507).
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).
Karim Fizazi, MD, PhD, of Institut Gustave Roussy, discusses first results from the phase III PEACE1 trial, which showed that abiraterone plus androgen-deprivation therapy and docetaxel improves radiographic progression-free survival in men with de novo metastatic prostate cancer (Abstract 5000).
Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, discusses two abstracts from a session she co-chaired: the phase II DEEPER trial, which explored the use of FOLFOXIRI plus cetuximab vs FOLFOXIRI plus bevacizumab as first-line treatment in metastatic colorectal cancer with RAS wild-type tumors; and the phase II FIRE-4.5 study, which investigated FOLFOXIRI plus either bevacizumab or cetuximab as first-line treatment of BRAF V600E–mutant advanced disease (Abstracts 3501 and 3502).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses results from the ADAPT HR–/HER2+ trial, which showed, for the first time, improved pathologic complete response and survival in patients with early breast cancer who were treated weekly with a de-escalated 12-week regimen of neoadjuvant paclitaxel plus pertuzumab and trastuzumab (Abstract 503).
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.
