Nab-Paclitaxel and Bevacizumab Followed By Bevacizumab and Erlotinib in Metastatic Breast Cancer

PRIMARY OBJECTIVES: I. Progression free survival. SECONDARY OBJECTIVES: I. Response rate. II. Overall survival. III. Safety and toxicity. IV. Exploratory biomarkers will be assessed as potential predictors of response to treatment including: expression of epidermal growth factor receptor (EGFR) and secreted protein acidic and rich in cysteine (SPARC) in the primary tumor and changes in levels of circulating tumor cells (CTCs) and circulating endothelial cells (CECs). OUTLINE: INDUCTION THERAPY: Patients receive paclitaxel albumin-stabilized nanoparticle formulation intravenously (IV) on days 1, 8, and 15 and bevacizumab IV over 30-90 minutes on days 1 and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY: Patients achieving complete response, partial response, or stable disease after completion of induction therapy will receive bevacizumab IV over 30-90 minutes once every 14 or 21 days and erlotinib hydrochloride orally (PO) once daily (QD) in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up per physician discretion.
