Recruiting now · Phase 2

Conditions studied: Breast Cancer, HER2-positive Breast Cancer

In brief

This study is intended to carry out a single arm, prospective, open clinical study, and use Darsilide combined with endocrine therapy, Trastuzumab and Patuzumab to treat early or locally advanced breast cancer of TPBC before surgery. It is intended to further explore the efficacy and safety of the new adjuvant treatment for TPBC patients with step-down therapy.
