Laurence Buisseret, MD, PhD, on Triple-Negative Breast Cancer: Chemoimmunotherapy With or Without an Anti-CD73 Antibody

Laurence Buisseret, MD, PhD, of Belgium’s Institut Jules Bordet, discusses phase II results from the SYNERGY trial, which tested first-line chemoimmunotherapy of durvalumab, paclitaxel, and carboplatin with or without the anti-CD73 antibody oleclumab in patients with advanced or metastatic triple-negative breast cancer. Although adding oleclumab to durvalumab with chemoimmunotherapy did not increase the clinical benefit rate at week 24, research is ongoing to better understand the mechanisms of response and resistance to this study combination (Abstract LBA17).

Anders, Erika Hamilton, and Sara A. Hurvitz discuss the management of HER2-positive residual disease. The patient is a 39-year-old premenopausal woman who is diagnosed with T2 N1 ER/PR-negative, HER2-positive breast cancer. She goes on to receive docetaxel/carboplatin/trastuzumab/pertuzumab for 6 cycles, but at surgery she is found to have T1c and N0 residual disease. The faculty discuss strategies to prevent recurrence in patients with residual disease, reviewing the findings of the KATHERINE trial of trastuzumab vs ado-trastuzumab emtansine. They also explore strategies to prevent CNS recurrence and review upcoming trials.

Her hepatomegaly resolves and liver metastases improve after 6 cycles of docetaxel/trastuzumab/pertuzumab, but during routine restaging scans she is found to have progression in the liver and the brain. The faculty discuss the clinical implications of two phase III studies in patients with breast cancer brain metastases: HER2CLIMB, which evaluated the addition of tucatinib to trastuzumab and capecitabine, and DESTINY-Breast03, which compared fam-trastuzumab deruxtecan-nxki to ado-trastuzumab emtansine.
