with other therapy. Trastuzumab must have been administered in the adjuvant, or
locally advanced or metastatic setting.

- Must have tumors that overexpress ErbB2 defined as +3 by IHC or FISH positive for
ErbB2 gene amplification. The status of ErbB2 expression must be documented prior to
study entry.

- Must be >/= 18 years of age

- Life expectancy of > 8 weeks

- Must have recovered from side effects of previous treatment

- Patients with CNS mets are eligible provided treatment with prohibited medications as

months from study entry; uncontrolled or symptomatic CHF; ejection fraction below the
institutional normal limit; any other cardiac condition that would make this protocol
