Dr. Sara Hurvitz, Director of the Breast Cancer Clinical Trials Program at UCLA, reviews key updates in HER2-positive metastatic breast cancer studies presented during the 2020 San Antonio Breast Cancer Symposium (SABCS), which was held virtually in December.
A sub-analysis of patients who had central nervous system disease at baseline demonstrated improved outcomes with neratinib plus capecitabine compared with those receiving lapatinib plus capecitabine in the NALA trial.
Updated results from the DESTINY-breast01 study of trastuzumab deruxtecan show encouraging results in progression-free survival and early overall survival and high rates of durable responses in a heavily pretreated group of patients with metastatic breast cancer, consistent with early results.
In the HER2CLIMB study, patients treated with tucatinib in combination with trastuzumab and capecitabine had clinically meaningful improvement in progression-free survival, overall survival, and objective response rate independent of HR status compared with placebo, and patients with HR+ and HR- breast cancer with brain metastases experienced similar benefits.
