Datopotamab deruxtecan significantly extended progression-free survival vs. chemotherapy in patients with HR-positive, HER2-low or negative breast cancer in TROPION-Breast01 Phase III trial
AstraZeneca and Daiichi Sankyo’s datopotamab deruxtecan reduced the risk of disease progression or death by 37%, providing a 2-month median PFS benefit, and was well tolerated in post-endocrine therapy setting. Positive results from the pivotal TROPION-Breast01 Phase III trial showed that datopotamab deruxtecan (Dato-DXd) demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared to investigator’s choice of chemotherapy in patients with inoperable or metastatic hormone receptor (HR)-positive, HER2-low or negative (IHC 0, IHC
