Clinical trials

There are no real-world data available on the effectiveness and safety of Dato-DXd in adult patients with unresectable or metastatic triple-negative breast cancer who are not candidates for PD-1/PD-L1 inhibitor therapy. This NIS will investigate the effectiveness of Dato-DXd, the demographic and clinical characteristics of the patients, and treatment patterns.

Trastuzumab deruxtecan (T-DXd) as monotherapy is indicated for the treatment of adult patients with unresectable or metastatic HER2-low breast cancer who have received prior chemotherapy in the metastatic setting or developed disease recurrence during or within 6 months of completing adjuvant chemotherapy. Based on the extended therapeutic indication of Trastuzumab deruxtecan (Enhertu®), a new patient population will be enrolled, comprising adult patients with unresectable or metastatic HR-positive, HER2-low, or HER2-(ultra)low breast cancer who have received at least one endocrine therapy in the metastatic setting and are not considered suitable for endocrine therapy as the next line of treatment.
