Anastrozole or fulvestrant plus fam-trastuzumab deruxtecan-nxki showed promising antitumor activity in patients with chemotherapy-naïve, HER2-low, hormone receptor-positive metastatic breast cancer.

Early findings from the DEBBRAH study suggest that fam-trastuzumab deruxtecan-nxki shows potential in treating patients with advanced HER2-positive, HER2-low breast cancer, including those with leptomeningeal carcinomatosis.

Datopotamab deruxtecan demonstrated a statistically significant and clinically meaningful improvement in progression-free survival compared with chemotherapy in patients with previously treated, hormone receptor-positive/HER2-negative inoperable or metastatic breast cancer.

The RELIEVE study looked at real-world patients receiving trastuzumab deruxtecan based on HER2 expression status and time to next treatment including in those whose HER2 status changed during course of treatment.
