|Condition or disease||Intervention/treatment||Phase|
|HER2-positive Breast Cancer Recurrent Breast Cancer Stage IV Breast Cancer||Drug: capecitabine Drug: cyclophosphamide Drug: lapatinib ditosylate Biological: trastuzumab Other: laboratory biomarker analysis||Phase 2|
I. To estimate the progression free survival (PFS).
I. To evaluate the overall response rate (ORR).
II. To evaluate the clinical benefit rate (CBR; complete response, partial response, and stable disease for >= 24 weeks).
III. To estimate the overall survival (OS).
IV. To assess the safety and tolerability.
Patients receive capecitabine orally (PO) once daily (QD), cyclophosphamide PO QD, and lapatinib ditosylate PO QD on days 1-21 and trastuzumab intravenously (IV) on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year.

Experimental: Treatment (chemotherapy, lapatinib ditosylate, trastuzumab)
Patients receive capecitabine PO QD, cyclophosphamide PO QD, and lapatinib ditosylate PO QD on days 1-21 and trastuzumab IV on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

- PFS [ Time Frame: From the date of registration to date of first documentation of progression or symptomatic deterioration or death due to any cause, assessed up to 1 year ]One-sided one-sample logrank test will be used to evaluate the improvement in PFS compared to the reported historical PFS rate.
