Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This trial combines dose dense chemotherapy with doxorubicin and cyclophosphamide (AC) followed by standard, every 3 week docetaxel and GW572016 (lapatinib) for neoadjuvant treatment of Her2neu positive stage II/III breast cancer. The purpose of the study was to determine whether lapatinib combined with chemotherapy was safe and resulted in an increase in pathologic complete response rates.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Lapatinib acts as a dual inhibitor of both epidermal growth factor receptor (EGFR) and ErbB-2 (Her2/neu) tyrosine kinase activity. EGFR and ErbB2 receptors are frequently over-expressed or altered in human cancers including breast cancer. This study plans to determine the antitumor activity of this regimen and its effectiveness preventing tumor growth and spread.

Neoadjuvant chemotherapy which achieves pathologic complete responses (pCR) has been shown to predict improved long-term survival and serves as a surrogate for clinical outcome. By using this primary endpoint we can obtain statistical data with smaller patient numbers and at a lower overall cost. Additionally, we hope to correlate clinical and radiologic outcomes with gene expression data.

Study Groups

Neoadjuvant Chemotherapy

Doxorubicin (Adriamycin) + cyclophosphamide (Cytoxan) with pegfilgrastim or filgrastim growth factor support every 2 weeks for 4 cycles, followed by docetaxel + lapatinib for four 21-day cycles, followed by surgery. Dexamethasone was administered twice-a-day for 3 days, starting 24 hours before the docetaxel infusions. After surgery +/- radiation, participants may receive trastuzumab (Herceptin) for a year.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Female

* Stage II/III breast cancer including any large primary tumor (\> 2 cm), tumors of any size associated with skin or chest wall involvement, tumors of any size with axillary lymph node involvement, (T2-T4, N0-N2) and those with ipsilateral subclavicular or supraclavicular lymph nodes).
* At least one bi-dimensional, measurable indicator lesion.
* Between 18 and 70 years of age
* Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 / Karnofsky ≥ 60% at screening and on the first day of treatment.
* Informed consent must be obtained prior to registration.
* Cardiac ejection fraction within the institutional range of normal as measured by multigated acquisition (MUGA) or echocardiography (ECHO) scan.
