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).

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).

Andrew Tutt, PhD, MBChB, of the Institute of Cancer Research, London, discusses findings from the phase III OlympiA trial, which showed that adjuvant olaparib, a PARP inhibitor, following adjuvant or neoadjuvant chemotherapy, may improve invasive disease–free survival in patients with germline BRCA-mutated and high-risk HER2-negative early breast cancer, which might lead to a new indication in this setting (Abstract LBA1).

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).
