Study Summary

Drugs used in chemotherapy, such as doxorubicin hydrochloride liposome and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. 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 more than one drug (combination chemotherapy) together with trastuzumab may be a better way to block tumor growth.

Primary Outcome

The dose level in which 2 or more patients develop treatment-related toxicity of grade 3 or higher OR require a dose adjustment following the first course of treatment
