What This Trial Is Studying

Patients with HER2-positive primary breast cancer (BC) who do not achieve complete response after appropriate neoadjuvant therapy are at higher risk of disease recurrence. More effective treatment options are needed for this patient population. This study will examine the efficacy and safety of trastuzumab deruxtecan (T-DXd) compared with trastuzumab emtansine (T-DM1) in high-risk patients with residual invasive breast cancer following neoadjuvant therapy. Conditions: HER2-Positive Primary Breast Cancer, Residual Invasive Breast Cancer Interventions: DS-8201a, T-DM1 Lead Sponsor: Daiichi Sankyo Planned Enrollment: 1635 participants
