Romidepsin and Abraxane in Treating Patients With Metastatic Inflammatory Breast Cancer

PRIMARY OBJECTIVES: 1. To assess the safety of the combination of romidepsin plus Abraxane (paclitaxel albumin-stabilized nanoparticle formulation) delivered weekly. (Phase I) 2. To determine the maximum tolerated dose (MTD) of romidepsin with full dose weekly Abraxane to define a recommended phase II doses of the combination. (Phase I) 3. To assess the progression-free survival (PFS) in patients with human epidermal growth factor receptor 2 (HER2) negative, newly diagnosed metastatic inflammatory breast cancer treated with the combination of romidepsin and Abraxane. (Phase II) SECONDARY OBJECTIVES: 1. To assess the safety and tolerability of the combination of romidepsin and Abraxane. 2. To determine the adverse event profile of the combination of romidepsin and Abraxane. 3. To assess the overall response rate (ORR) and clinical benefit rate (CBR) in patients with newly recurrent inflammatory breast cancer (IBC) treated with the combination of romidepsin and Abraxane. OUTLINE: This is a phase I, dose-escalation study of romidepsin followed by a phase II study. Patients receive paclitaxel albumin-stabilized nanoparticle formulation intravenously (IV) over 30 minutes and romidepsin IV over 60 minutes on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.
