Brief Summary

RATIONALE: Drugs used in chemotherapy, such as docetaxel, fluorouracil, epirubicin, and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Lapatinib 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 cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving these treatments before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving trastuzumab after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of docetaxel and lapatinib when given with or without combination chemotherapy and to see how well they work in treating women with locally advanced, inflammatory, or resectable breast cancer.

Detailed Description

OBJECTIVES:

Primary

• Determine the maximum tolerated dose of neoadjuvant therapy comprising docetaxel and lapatinib ditosylate before or after fluorouracil, epirubicin hydrochloride, and cyclophosphamide (FEC chemotherapy) in patients with HER2-positive locally advanced, inflammatory, or large resectable breast cancer. (Phase I)
• Determine the safety of this regimen in these patients. (Phase I)
• Determine the pathological complete response rate in patients treated with neoadjuvant docetaxel and lapatinib ditosylate followed by FEC chemotherapy, and with neoadjuvant docetaxel and trastuzumab (Herceptin®) followed by FEC chemotherapy. (Phase II)

Secondary

• Determine the biological activity (i.e., changes in apoptosis and proliferation markers [PTEN mutation and function, pAkt, mTOR, and associated proteins]) of neoadjuvant docetaxel and lapatinib ditosylate in these patients. (Phase I)
• Determine adverse events or biological modifications. (Phase I)
• Determine the tolerability of these regimens in these patients. (Phase II)
• Determine the clinical activity of these regimens. (Phase II)
• Identify genes that may predict response in patients treated with docetaxel and lapatinib ditosylate. (Phase II)

OUTLINE: This is a multicenter, open-label, phase I dose-escalation study of docetaxel and lapatinib ditosylate followed by a randomized phase II study. Patients enrolled in the phase II portion of the study are stratified by institution and disease status (locally advanced disease vs large operable tumor).

• Phase I (completed as of 5/26/2010): Patients receive docetaxel IV over 1 hour on day 1 and oral lapatinib ditosylate once daily on days 1-21. Treatment repeats every 3 weeks for 4 courses. Two additional courses may be given at the discretion of the physician.

• Cohorts of 3-6 patients receive escalating doses of docetaxel and lapatinib ditosylate until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity (DLT).
• Phase I bridge step (completed as of 5/26/2010): Patients receive FEC chemotherapy comprising fluorouracil IV over 15 minutes, epirubicin hydrochloride IV over 60 minutes, and cyclophosphamide IV over 60 minutes on day 1. Treatment repeats every 3 weeks for 3 courses. Patients also receive docetaxel and lapatinib ditosylate as in phase I at the MTD for up to 3 courses.

• Cohorts of 3-6 patients receive de-escalating doses of docetaxel and lapatinib ditosylate in combination with FEC chemotherapy until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience DLT.
• Phase II: Patients are randomized to 1 of 3 treatment arms.

• Arm I: Patients receive docetaxel and lapatinib ditosylate at the MTD as in the bridge step of phase I followed by FEC chemotherapy.
• Arm II: Patients receive docetaxel IV over 60 minutes and trastuzumab (Herceptin®) IV over 30-90 minutes on days 1, 8, and 15. Patients then receive FEC chemotherapy as in the bridge step of phase I. Treatment with docetaxel and trastuzumab repeats every 3 weeks for 3 courses in the absence of disease progression or unacceptable toxicity.
• Arm III: Patients receive docetaxel IV over 60 minutes, lapatinib ditosylate at the MTD as in the bridge step of phase I, and trastuzumab (Herceptin®) IV over 30-90 minutes on days 1, 8, and 15. Patients then receive FEC chemotherapy as in the bridge step of phase I. Treatment with docetaxel, lapatinib ditosylate, and trastuzumab repeats every 3 weeks for 3 courses in the absence of disease progression or unacceptable toxicity.

All patients then undergo surgery to remove the tumor. Patients may then receive trastuzumab every 3 weeks for 1 year.

Blood samples are collected at baseline and periodically during study for pharmacokinetic studies. Patients also undergo tumor biopsies at baseline and periodically during study for laboratory studies. Blood and tissue samples are analyzed by quantitative reverse transcriptase polymerase chain reaction for biomarker profiling (HER1-3, Akt 1-3, mTOR, RICTOR, RAPTOR, CCND1, p21, survivin, PTEN), immunohistochemistry, fluorescent in situ hybridization (TopoII, HER2), and proteomics.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 150 patients will be accrued for the phase II.
