Study Details
Study Description
Brief Summary
This is a multicenter, randomized, double-blind, parallel-controlled Phase III study to evaluate the efficacy and safety of TQB2440 injection/Perjeta® combined with trastuzumab and docetaxel in patients with early or locally advanced ER/ PR-negative HER2-positive breast cancer. The trial is scheduled to enroll 412 participants. The sample size was estimated based on 20 treatment cycles and 6 recurrence visits.

|---|---|
| Experimental: 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. |
Drug: TQB2440 injection + Trastuzumab + Docetaxel
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.

Drug: Perjeta + Trastuzumab + Docetaxel
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.
