Study Groups

TQB2440 injection + Trastuzumab + docetaxel

Neoadjuvant phase (cycle 1-4):

TQB2440 injection + Trastuzumab + Docetaxel, intravenous infusion on the first day of each cycle, each cycle is 21 days.

Adjuvant chemotherapy phase (cycle 5-7):

Fluorouracil (600 mg/m2)+Epirubicin (90 mg/m2)+Cyclophosphamide (600mg/m2), intravenous injection once a day, on the first day of each cycle, each cycle is 21 days.

Double targeted maintenance phase (cycle 8-20):

TQB2440 injection+Trastuzumab, intravenous infusion on the first day of each cycle, each cycle is 21 days.

Group Type: EXPERIMENTAL

TQB2440 injection + Trastuzumab + Docetaxel

Intervention Type: DRUG

TQB2440 injection is a biosimilar of Perjeta® (Pertuzumab injection) developed by Chia Tai Tianqing Pharmaceutical Group. Trastuzumab is a recombinant DNA-derived human IgG monoclonal antibody against P185 glycoprotein regulated by HER2 gene in cell nucleus. Docetaxel is a selective L-type calcium channel blocker.

Fluorouracil + epirubicin + cyclophosphamide for 3 cycles is a routine chemotherapy method after neoadjuvant surgery for breast cancer.

The combination of Pertuzumab and Trastuzumab will enhance the antitumor activity and is used as the double targeted maintenance.

Group Type: ACTIVE_COMPARATOR

Perjeta + Trastuzumab + Docetaxel

Intervention Type: DRUG

Perjeta® with the general name Pertuzumab injection, is a recombinant humanized monoclonal antibody targeting the extracellular second domain of human epidermal growth factor receptor 2 (HER2). Trastuzumab is a recombinant DNA-derived human IgG monoclonal antibody against P185 glycoprotein regulated by HER2 gene in cell nucleus. Docetaxel is a selective L-type calcium channel blocker.

Fluorouracil + epirubicin + cyclophosphamide for 3 cycles is a routine chemotherapy method after neoadjuvant surgery for breast cancer.

The combination of Pertuzumab and Trastuzumab will enhance the antitumor activity and is used as the double targeted maintenance.
