Lapatinib Ditosylate, Trastuzumab, Paclitaxel, and Surgery in Treating Patients With Breast Cancer

Brief Summary
This phase II trial studies how well giving lapatinib ditosylate together with trastuzumab, paclitaxel, and surgery works in treating patients with breast cancer. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor to grow and spread. Others find tumor cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

Outcome Measures
Primary Outcomes (2)
Expression of ALDH1 and CD44v Change in the Binary Biomarkers From Baseline to 6 Weeks and 18 Weeks
For biomarkers ALDH1 and CD44v, the change in the proportions of CD44v-positive (CD44v+) tumor cells and ALDH1-positive (ALDH1+) tumor cells in tumor tissue from baseline to 6 weeks and 18 weeks time points were determined for each patient. For biomarker change, changes in the binary biomarkers between time points were assessed using McNemar's test in all patients and separately in patients with and without pCR.
From baseline to 18 weeks
Number of Participants With Pathological Complete Response (pCR)
The point estimate of the pCR rate will be calculated for all patients. pCR is defined as the abscence of invasive cancer in the breast and regional lymph nodes following neoadjuvant chemotherapy.
Up to 12 weeks
Secondary Outcomes (3)
Cellular Response Rate, Defined as Patients With an Epithelial Phenotype Having Eradication of CTCs; Patients With a Mesenchymal Phenotype Having Eradication of Tumor Cells; Patients With a Mesenchymal Phenotype Converting to an Epithelial Phenotype
Up to 18 weeks
EGFR-mutation Status of Tumors and Changes in the Ratio of Phosphorylated to Nonphosphorylated HER2, EGFR, ERK, Akt, and the Ki67 and TUNEL Indices Before and After Treatment
From baseline to 24 weeks
Number of Participants With Treatment-Related Toxicities
Up to 12 weeks after completion of study treatment
Study Arms (1)
Treatment (lapatinib, trastuzumab, paclitaxel, surgery)
EXPERIMENTALDrug exposure: Patients receive lapatinib ditosylate PO QD and trastuzumab IV over 30-90 minutes once weekly for 6 weeks in the absence of disease progression or unacceptable toxicity. Preoperative therapy: Patients receive lapatinib ditosylate PO QD, trastuzumab IV over 30 minutes once weekly, and paclitaxel IV over 90 minutes once weekly for 12 weeks in the absence of disease progression or unacceptable toxicity. Patients then undergo lumpectomy or mastectomy.
