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).

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).
The ASCO Post Staff
Thierry André, MD, of Hôpital Saint-Antoine, discusses final overall survival data for the phase III KEYNOTE-177 study, which confirmed pembrolizumab as a new standard of care for first-line treatment of patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract 3500).
The ASCO Post Staff
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).

Sibylle Loibl, MD, PhD, of the German Breast Group, discusses results from the phase III GeparNUEVO study, which investigated neoadjuvant durvalumab in addition to anthracycline/taxane-based neoadjuvant chemotherapy in patients with early triple-negative breast cancer (Abstract 506).

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).
