Melinda L. Telli, MD, on Breast Cancer: Neoadjuvant Talazoparib for Early HER2-Negative Disease
2021 ASCO Annual Meeting
Melinda L. Telli, MD, of Stanford University, discusses results of a phase II study on neoadjuvant talazoparib in germline BRCA1/2 mutation–positive, early HER2-negative breast cancer. In this setting, talazoparib monotherapy was active and yielded pathologic complete response rates comparable to those observed with combination anthracycline and taxane-based chemotherapy regimens (Abstract 505).

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.

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).

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).

Michael J. Morris, MD, of Memorial Sloan Kettering Cancer Center, discusses phase III results of the VISION study, which showed that lutetium-177–PSMA-617 (LuPSMA), a targeted radioligand therapy, plus standard-of-care treatment improves radiographic progression-free survival and extends overall survival compared with standard of care alone in men with metastatic castration-resistant prostate cancer (Abstract LBA4).

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).
