DESTINY Breast Respond HER2-(Ultra)Low Europe
brief summary
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.
detailed description
This non-interventional study will investigate the effectiveness of T-DXd, the demographic and clinical characteristics of the patients, treatment patterns, tolerability, management of adverse drug reactions (ADRs), and patient experience of T-DXd in patients with HER2-low and HER2-(ultra)low unresectable and/or metastatic breast cancer. Patients will be treated according to the proposed indication statement in the Summary of Product Characteristics (SmPC). No drug product will be administered as part of this study.
Data on conventional chemotherapy (i.e., including but not limited to capecitabine, eribulin, gemcitabine, paclitaxel and nab-paclitaxel) will also be collected in a disease registry part of the study. For Study Group 2, only baseline data will be collected for patients treated with conventional chemotherapy.
