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.

Primary Outcome Measures:
  • Rate of pathologic complete response [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • Treatment related toxicities [ Time Frame: 12 weeks ]
  • Breast conservation rates [ Time Frame: 16 weeks ]
  • Clinical response rates [ Time Frame: 1 year ]
  • Relapse free survival (RFS) [ Time Frame: 2 years ]
  • Identification of tumor biomarkers that predict pathologic complete response [ Time Frame: 16 weeks ]

Estimated Enrollment: 34
Study Start Date: April 2011
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pre-operative Therapy
Neoadjuvant paclitaxel/carboplatin/lapatinib x 12 weeks
Drug: paclitaxel/carboplatin/lapatinib

Drug doses for the neoadjuvant regimen:

  • Paclitaxel 80mg/m2, day 1, 8, 15 of a 21-day cycle
  • Carboplatin AUC of 2, day 1, 8 of a 21-day cycle
  • Lapatinib 750mg daily continuously

Detailed Description:
  • 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%
