Roisin M. Connolly, MD, on HR+ Advanced Breast Cancer: Endocrine Therapy and Entinostat
2020 San Antonio Breast Cancer Symposium
Roisin M. Connolly, MD, of University College Cork, discusses phase III results from the E2112 trial, which showed exemestane plus entinostat did not improve survival in aromatase inhibitor–resistant advanced HR-positive, HER2-negative breast cancer (Abstract GS4-02).
Sibylle Loibl, MD, of the German Breast Group, discusses the first phase III results from the PENELOPE-B study of palbociclib combined with endocrine therapy in patients with hormone receptor–positive, HER2-negative primary breast cancer who are at high risk for relapse after neoadjuvant chemotherapy (Abstract GS1-02).
Lee S. Schwartzberg, MD, of the West Cancer Center, discusses phase III results from the CONTESSA study, which showed that an all-oral regimen of tesetaxel plus a reduced dose of capecitabine significantly improved progression-free survival compared with capecitabine alone in patients with HER2-negative, hormone receptor–positive metastatic breast cancer previously treated with a taxane (Abstract GS4-01).
Editor's note: On March 22, 2021, Odonate Therapeutics announced it was discontinuing the development of tesetaxel and will close the company's operations. Read more here.
Joyce V. Lee, PhD, of the University of California, San Francisco, discusses data that suggest the MYC oncogene may indicate whether a patient with triple-negative breast cancer will respond to immunotherapy. Dr. Lee’s study is the first to describe MYC downregulation of MHC-I and to demonstrate translatable approaches that may overcome immune evasion (Abstract GS1-08).
Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, discusses results from the ALTERNATE trial on response to neoadjuvant chemotherapy in postmenopausal women with clinical stage II or III estrogen receptor–positive and HER2-negative breast cancer that is resistant to endocrine therapy. The findings highlight the need for more effective treatments in this high-risk population (Abstract GS4-05).
Nadia Harbeck, MD, of the University of Munich, discusses the first outcome data from the phase III ADAPT HR+/HER– trial, which combined both static and dynamic biomarkers to optimize the adjuvant therapy approach in patients with intermediate- or high-risk luminal early breast cancer (Abstract GS4-04).
