简要总结
The purpose of this study is to evaluate the Safety and Efficacy of Neoadjuvant study of DV in combination Toripalimab i or sequence chemotherapy in HR-negative, HER2 low-expressing Breast Cancer
详细描述
This is an open-label, randomized, multicenter, Phase II Neoadjuvant Therapy Study designed to evaluate the Safety and Efficacy of Neoadjuvant study of DV in combination Toripalimab or sequence chemotherapy in HR-negative, HER2 low-expressing Breast Cancer The primary objectives of the study are to explore combination neoadjuvant therapy in participants with previously untreated HR-negative, HER2 low-expressing breast cancer, by assessment of tpCR and EFS.
