Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Real-World Time-to-Treatment Discontinuation In Participants Treated With Trastuzumab Deruxtecan (T-DXd)	Real-world time-to-treatment discontinuation (rwTTD) is defined as the time from trastuzumab deruxtecan initiation to discontinuation for any reason in patients with advanced/metastatic HER2+ breast cancer in a real-world clinical setting.	From the time from T-DXd initiation to the date of T-DXd discontinuation, up to 14 months
Secondary	Type of Prior Targeted HER2-targeted Treatments In Participants Treated With Trastuzumab Deruxtecan (T-DXd)		Prior to time of T-DXd initiation
Secondary	Number of Participants Who Discontinued Trastuzumab Deruxtecan (T-DXd) In Participants Treated With T-DXd		From the time from T-DXd initiation to the date of T-DXd discontinuation, up to 14 months
Secondary	Number of Participants With Treatment-emergent Adverse Events In Participants Treated With Trastuzumab Deruxtecan (T-DXd)		From the time from T-DXd initiation to the date of T-DXd discontinuation, up to 14 months
Secondary	Number of Participants Who Received Prophylaxis Treatment In Participants Treated With Trastuzumab Deruxtecan (T-DXd)	Patients who received prophylaxis treatment for nausea and/or vomiting will be reported.	Prior to time of T-DXd initiation
Secondary	Real World Progression-free Survival In Participants Treated With Trastuzumab Deruxtecan (T-DXd)	Real world progression-free survival (rwPFS) is defined as the time from T-DXd initiation to the earliest of death or progression.	From the time of T-DXd initiation to the date of T-DXd discontinuation, withdrawal, or disease progression, up to 14 months
