“A Phase 3, Multicenter, Randomized, Open-Label, Active-Controlled Study of Trastuzumab Deruxtecan (T-DXd) Versus Trastuzumab Emtansine (T-DM1) in Subjects with High-Risk HER2-Positive Primary Breast Cancer Who Have Residual Invasive Disease in Breast or Axillary Lymph Nodes Following Neoadjuvant Therapy”
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.
