简要总结
The purpose of this study is to evaluate the efficacy and safety of weekly paclitaxel and carboplatin, in combination with lapatinib, in the neoadjuvant treatment of non-metastatic erbB2-positive breast cancer.
Secondary objectives include:
- To determine the safety and tolerability of weekly paclitaxel and carboplatin, combined with lapatinib, in an Asian population
- To determine breast conservation rates following neoadjuvant paclitaxel/ carboplatin/ lapatinib
- To determine clinical response rates and relapse-free survival of patients treated with neoadjuvant paclitaxel/ carboplatin/ lapatinib
- To identify predictive tumour biomarkers for pathologic complete response
The investigators hypothesize that pathologic complete response rates will be improved from 15% to 35% with the neoadjuvant regimen of carboplatin/ paclitaxel/ lapatinib compared to standard chemotherapy alone in HER2 positive early stage breast cancers.
详细描述
- Pathologic complete response following neoadjuvant chemotherapy has been shown to be an independent, strong predictor of disease-free and overall survival in operable breast cancer
- The addition of neoadjuvant trastuzumab to chemotherapy results in a 2-3 fold increase in pCR rates in operable ErbB2-positive breast cancer
- Lapatinib is being explored as an alternative to trastuzumab in large clinical trials in operable ErbB2-positive breast cancer
- In a randomised phase III adjuvant trial, BCIRG 006, non-anthracycline chemotherapy (docetaxel and carboplatin) has been shown to be as effective as conventional sequential anthracycline-containing chemotherapy and docetaxel, in combination with trastuzumab, but with improved cardiac safety
- Weekly paclitaxel has been shown in a randomized phase III study to be the optimal adjuvant taxane regimen
- Weekly paclitaxel and carboplatin, in combination with lapatinib, has demonstrated safety and efficacy in Phase I/II clinical studies of metastatic breast and ovarian cancer
- The investigators aim to assess the efficacy of a non-anthracycline containing regimen, weekly paclitaxel and carboplatin, in combination with lapatinib in inducing pCR in the neoadjuvant treatment of ErbB2-positive non-metastatic breast cancer. The investigators hypothesize that this combination will achieve pCR rates of at least 35%
