HER2+ Early or Locally Advanced Breast Cancer Clinical Trial
Official title:
Pyrotinib Versus Pertuzumab in Combination With Neoadjuvant Trastuzumab and Nab-Paclitaxel in HER2+ Early or Locally Advanced Breast Cancer
The study is being conducted to evaluate the efficacy, and safety of pyrotinib versus pertuzumab in combination with trastuzumab and nab-paclitaxel for neoadjuvant treatment in HER2+ early or locally advanced breast cancer patients. To explore whether pyrotinib regimen could provide better clinical results compared with pertuzumab in the study population.
This study is a multi-center, randomized, open-label, controlled trial. Eligible patients will be randomized to neoadjuvant pyrotinib or pertuzumab containing regimen every 3 weeks for four cycles before surgery. Randomization was stratified by the following factors: hormone receptor status and primary tumor size. After completing four cycles of neoadjuvant treatment, all patients who are eligible for surgery will undergo surgery and have their pathologic response evaluated. Following surgery, patients will receive 90-100 mg/m2 epirubicin and 600 mg/m2 cyclophosphamide every 3 weeks for 4 cycles. Clinicians will select subsequent treatments for patients based on guidelines as well as clinical practice at each site. ;
