The antibody-drug conjugate T-DXd has been granted conditional approval in the European Union as a single agent for adult patients with unresectable or metastatic HER2+ breast cancer who have previously received ≥2 HER2-based regimens. This was based on data from the Phase II DESTINY-Breast01 trial (NCT03248492).~DS8201-0002-EAP-MA is a real world data (RWD) observational data collection inviting patients with advanced/metastatic HER2+ breast cancer receiving T-DXd through the NPP already to participate to help further understand the usage in a real world clinical setting.
A named patient program (NPP) was initiated to allow patients with an unmet medical need to access trastuzumab deruxtecan (T-DXd) treatment. To gain early insights on the use of T-DXd outside of a trial setting, patients with advanced/metastatic HER2+ breast cancer receiving treatment (or previously treated) with T-DXd through the NPP will be invited to participate.
