Primary Outcome Measures:

Phase I: To evaluate the safety and tolerability of several dose levels of CPG 7909 (up to a maximum of 0.16 mg/kg) and to determine the maximum tolerated dose (MTD)* of CPG 7909 in combination with Herceptin® [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
Phase II: To evaluate tumor response and safety of CPG 7909 (at the MTD as determined in Phase I) in combination with Herceptin® in patients with metastatic breast cancer. [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Phase I To evaluate tumor response, duration of response, time to disease progression, ECOG performance status, and survival time. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Phase II To evaluate duration of response, time to disease progression, ECOG performance status, and survival time. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Eligibility

Criteria

Inclusion Criteria:

Histologically confirmed breast cancer with metastases
Tumor that has overexpression of HER2 as documented by being either FISH-positive or HER2/neu 3+ confirmed by immunohistochemistry
Patients may have had up to three prior chemotherapy regimens for metastatic disease, which may have been given in combination with Herceptin® and which may have been discontinued due to toxicities. In addition, patients may have had adjuvant chemotherapy.
Phase II only: Must have measurable disease by RECIST criteria (defined in section 8) with at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as > 20 mm with conventional techniques, or as > 10 mm with spiral CT scan

Exclusion Criteria:

Any prior therapy with anthracycline + Herceptin® concurrently
Significant cardiovascular disease (e.g., NYHA class 3 congestive heart failure, myocardial infarction within the past 6 months, unstable angina; coronary angioplasty within the past 6 months, uncontrolled atrial or ventricular cardiac arrhythmias) or left ventricular ejection fraction < 50%
Pre-existing autoimmune or antibody-mediated diseases including but not limited to: systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, Sjogren's syndrome, autoimmune thrombocytopenia
