Summary
Brief summary (as posted)
This study is a multicenter, randomized, open-label, parallel Phase III clinical trial. 650 early-stage or locally advanced breast cancer participants will be enrolled and randomly assigned to SHR-A1811 monotherapy group (trial group) or TCbHP treatment group (control group) at a 1:1 ratio. Participants will receive neoadjuvant treatments of SHR-A1811 or TCbHP, while those who have completed neoadjuvant therapy and are suitable for surgery must undergo surgical treatment. The participants will be evaluated on tumor efficacy through postoperative pathological assessment by IRC and pathologists from the research center. The primary endpoint will be tpCR evaluated by IRC. Participants who complete surgical treatment will be followed up for at least 3 years at study endpoints such as EFS, DFS, and DDFS.
