A Phase 3 Open-label Trial of Neoadjuvant Trastuzumab Deruxtecan (T-DXd) Monotherapy or T-DXd Followed by THP Compared to ddAC-THP in Participants With High-risk HER2-positive Early-stage Breast Cancer (DESTINY-Breast11)
A Phase 3 Open-label Trial of Neoadjuvant Trastuzumab Deruxtecan (T-DXd) Monotherapy or T-DXd Followed by THP Compared to ddAC-THP in Participants With High-risk HER2-positive Early-stage Breast Cancer (DESTINY-Breast11)
This study will look at the efficacy and safety of trastuzumab deruxtecan (T-DXd) in a neoadjuvant setting, in high-risk, HER2-positive early non-metastatic breast cancer.
The target population of interest in this study is participants with high-risk HER2-positive early-stage breast cancer. The purpose of this study is to determine the efficacy and safety of T-DXd neoadjuvant therapy.
Participants will be randomised to one of 3 arms: T-DXd monotherapy (Arm A), T-DXd followed by THP (Arm B), or ddAC-THP (Arm C).
