简要总结
This is a randomized, open, positive drug control, multi center phase III study. Through the evaluation of tpCR, bpCR, ORR, EFS, IDFS, OS , AEs and other indicators, it proves the effectiveness and safety of TQB2102 for injection versus TCbHP in the neoadjuvant treatment of HER2 positive breast cancer patients.
