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).

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).

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).

Neeraj Agarwal, MD, of Hunstman Cancer Institute at the University of Utah, discusses efficacy and safety results from the COSMIC-021 study, in which cabozantinib plus atezolizumab demonstrated clinically meaningful activity and a manageable safety profile in patients with metastatic castration-resistant prostate cancer. The findings support a phase III study of these agents vs a second line of novel hormonal therapy (Abstract LBA24).

Gabriel N. Hortobagyi, MD, of The University of Texas MD Anderson Cancer Center, discusses results from the MONALEESA-2 trial, which showed that adding the CDK4/6 inhibitor ribociclib to first-line hormonal therapy prolongs survival by 1 year for postmenopausal women with hormone receptor–positive, HER2-negative advanced breast cancer. As a result, he believes it should be considered the preferred treatment option (Abstract LBA17).

Karim Fizazi, MD, PhD, of the Institut Gustave Roussy, discusses phase III results from the PEACE-1 study, which showed that androgen-deprivation therapy plus docetaxel and abiraterone provided 2.5 years of additional time without radiographic disease progression or death and 1.5 additional years of survival in men with de novo high-volume metastatic castration-sensitive prostate cancer (Abstract LBA5).
