Hope S. Rugo, MD, on Triple-Negative Breast Cancer: Treatment Findings From KEYNOTE-355 on Pembrolizumab and Chemotherapy
ESMO Congress 2021
Hope S. Rugo, MD, of the University of California, San Francisco, discusses phase III results from the KEYNOTE-355 study of pembrolizumab plus chemotherapy, which improved overall survival vs chemotherapy alone in patients with previously untreated locally recurrent, inoperable, or metastatic triple-negative breast cancer whose tumors expressed PD-L1 (Abstract LBA16).

Naveen S. Vasudev, PhD, MBChB, of the University of Leeds, discusses phase II results from the PRISM trial, which showed that giving ipilimumab every 12 weeks instead of every 3 weeks, in combination with nivolumab, led to lower rates of grade 3 and 4 toxicities in patients with advanced renal cell carcinoma. Efficacy appeared to be comparable between both arms (Abstract LBA29).

Nicoletta Colombo, MD, of the Istituto Europeo Oncologico, discusses phase III results that showed improvements in progression-free and overall survival with a combination of pembrolizumab plus chemotherapy, compared with placebo and chemotherapy, for patients with persistent, recurrent, or metastatic cervical cancer. These benefits were seen regardless of PD-L1 expression and concomitant bevacizumab use, suggesting that pembrolizumab plus chemotherapy, with or without bevacizumab, may be a new standard of care for this population (Abstract LBA2).

Helena M. Earl, MBBS, PhD, of the University of Cambridge, discusses an individual patient data meta-analysis of noninferiority randomized clinical trials to determine whether a duration of less than the standard of 12 months of adjuvant trastuzumab is noninferior for treatment outcomes in patients with HER2-positive early breast cancer (Abstract LBA11).

Jenny F. Seligmann, MBChB, PhD, of the University of Leeds, discusses phase II findings that suggest adavosertib improved progression-free survival, compared with active monitoring, by inhibiting the WEE1 kinase in patients with RAS- and TP53-mutant metastatic colorectal cancer. In the trial, adavosertib’s activity tended to be even greater in left-sided tumors (Abstract 382O).

Robin Cornelissen, MD, PhD, of Erasmus University in Rotterdam, discusses phase II findings from the ZENITH20-4 study, which explored the question of whether poziotinib could benefit patients whose newly diagnosed non–small cell lung cancer harbors EGFR and HER2 exon 20 mutations. Potentially, this novel tyrosine kinase inhibitor may fill an unmet medical need (Abstract LBA46).
