This phase II trial studies how well erlotinib hydrochloride and bevacizumab work in treating patients with stage IV breast cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Giving erlotinib hydrochloride and bevacizumab may be an effective treatment for breast cancer.

PRIMARY OBJECTIVES:

I. To determine the efficacy of bevacizumab in combination with OSI-774 (erlotinib hydrochloride) in patients with previously treated metastatic breast cancer, as measured by objective response rate.

SECONDARY OBJECTIVES:

I. To determine the toxicity of bevacizumab in combination with OSI-774 in patients with previously treated metastatic breast cancer.

II. To evaluate the efficacy of bevacizumab in combination with OSI-774 in patients with previously treated metastatic breast cancer, as measured by time to disease progression, duration of response and the proportion of patients with stabilization of disease >= 6 months.

III. To determine the molecular profile of the patient's primary breast tumor, and to explore the relationship between these molecular characteristics and the response to treatment.

IV. To explore changes in biological markers in pre- and post-treatment tumor tissue in a subset of patients with accessible sites of disease.

V. To explore a pre- and post-treatment analysis of circulating endothelial cells and the relationship of this analysis to serum markers of angiogenesis as well as response to treatment.

VI. To obtain serial measurements of circulating epithelial cells and explore the relationship of these cells with circulating endothelial cells, markers of angiogenesis, and epidermal growth factor receptor (EGFR) expression.

OUTLINE:

Patients receive erlotinib hydrochloride orally (PO) once daily (QD) on days 1-21 and bevacizumab intravenously (IV) over 30-90 minutes 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 periodically.

• Women of childbearing potential must agree to use adequate contraception (barrier method of birth control) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

• Patients may not be receiving any other investigational agents
• History or evidence upon physical examination of central nervous system (CNS) disease (e.g., primary brain tumor, seizures not controlled with standard medical therapy, any brain metastases, or history of stroke); all subjects must have a baseline CT or magnetic resonance imaging (MRI) of the head
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to OSI-774 or bevacizumab
• Prior treatment with kinase insert domain receptor (KDR) inhibitors (e.g. vascular endothelial growth factor [VEGF] Trap, Su5416, Su6668, ZD6474, PTK757, IMC-1CII)
• Prior treatment with EGFR targeting therapies (e.g. ZD1839 or C225)
• Major surgery, open biopsy or significant traumatic injury occurring within 28 days prior to treatment; this does not apply to indwelling catheters, which require an interval of at least 24 hours between placement of the catheter and treatment with bevacizumab
• Current or recent (within 10 days prior to treatment) use of full-dose oral or parenteral anticoagulants or thrombolytic agents (except as required to maintain patency of preexisting, permanent indwelling IV catheters; for subjects receiving warfarin, international normalized ratio [INR] should be < 1.5)
