Study Of Lapatinib In Patients With Relapsed Or Refractory Inflammatory Breast Cancer

Summary

This study was designed to determine how effective and safe a new investigational drug, lapatinib, is in treating patients with treatment refractory or relapsed inflammatory breast cancer. Tumor tissue collected pre-treatment and at Day 28 will be examined for biologic activity by IHC (immunohistochemistry). Treatment will consist of daily oral therapy with lapatinib. A patient may continue treatment as long as they are receiving benefit. Blood samples for hematology and chemistry panels, MUGA/ECHO (multigated acquisition/echocardiogram) exams and physical exams will be performed throughout the study to monitor safety.
