A Study of Dato-DXd With or Without Durvalumab Versus Investigator's Choice of Therapy in Patients With Stage I-III Triple-negative Breast Cancer Without Pathological Complete Response Following Neoadjuvant Therapy (TROPION-Breast03)

The study will investigate the efficacy and safety of Dato-DXd with or without durvalumab when compared with ICT (capecitabine and/or pembrolizumab) in participants with stage I to III TNBC who have residual invasive disease in the breast and/or axillary lymph nodes at surgical resection following neoadjuvant systemic therapy. The primary objective of the study is to demonstrate superiority of Dato-DXd in combination with durvalumab relative to ICT by assessment of iDFS in participants with stage I to III TNBC with residual invasive disease at surgical resection following neoadjuvant therapy.
