I. To determine the recommended phase II dose of oral suberoylanilide hydroxamic acid (vorinostat) in combination with weekly paclitaxel and bevacizumab in patients with chest wall recurrent or metastatic breast cancer. (Phase I) II. To determine the efficacy (response rate, response duration, time to disease progression, time to treatment failure, and overall survival) and toxicity of oral suberoylanilide hydroxamic acid (vorinostat) in combination with weekly paclitaxel and bevacizumab in patients with chest wall recurrent or metastatic breast cancer. (Phase II)
I. To determine whether in vivo treatment with vorinostat induces a) acetylation of proteins including histone H3 and H4, b) ubiquitylation of proteins, and c) the levels of p21 and p27 levels in the peripheral blood mononuclear cells (pre treatment vs. cycle 1 day 2 after 3 VORINOSTAT doses but prior to paclitaxel.
II. To determine whether in vivo treatment with vorinostat induces a) acetylation of proteins including histone H3 and H4, ubiquitylation of proteins, and c) the levels of Bim, Bak, tBID, p21 and p27 levels, as well as down regulate Bcl-2, Bcl-xL and survivin in chest wall recurrent or metastatic breast cancer cells (pre treatment vs. cycle 1 day 2 after 3 vorinostat doses but prior to paclitaxel).
III. To determine whether in the primary breast cancer (and metastatic cancer if available) pretreatment levels of Her-2, Estrogen Receptor (ER)-alpha, Progesterone Receptor (PR), p21, p27, p-AKT, p-ERK1/2, HDAC1, 2, 3, 4, 6, 10 and SIRT2 levels predict for the response to treatment with VORINOSTAT plus paclitaxel.
OUTLINE: This is a phase I, multicenter, dose-escalation study of vorinostat (SAHA) followed by a phase II, open-label study.
Phase I: Patients receive oral SAHA twice daily on days 1-3, 8-10, and 15-17, paclitaxel IV over 1 hour on days 2, 9, and 16, and bevacizumab IV over 30-90 minutes on days 2 and 16. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of SAHA until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. The recommended phase II dose is defined as one dose level below the MTD.
Phase II: Patients receive SAHA at the recommended phase II dose and paclitaxel and bevacizumab as in phase I.

Experimental: vorinostat, paclitaxel, bevacizumab
Vorinostat BID on days 1-3, 8-10, and 15-17, paclitaxel IV over 1 hour on days 2, 9, and 16, bevacizumab IV over 30-90 minutes on days 2 and 16, repeat every 28 days.
- Recommended Phase II Dose as Assessed by NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 (Phase I) [ Time Frame: 28 days ]Dose-limiting toxcities (DLT) were defined as grade 3-4 febrile neutropenia, thrombocytopenia and non-hemtological toxicity attributed to therapy (nausea, vomiting and diarrhea would be considered dose limiting only if not adequately controlled with therapy). Any toxicity occurring during cycle 1 that resulted in dose reduction of vorinostat or paclitaxel or failure to complete all protocol specificed doses in the first cycle was also considered a DLT
- Objective Response Rate (CR + PR) [ Time Frame: Up to 12 months ]Estimated and a 95% confidence interval will be estimated via binomial proportions. Per Response Evaluation Criteria in Solid Tumors (RECIST) for target lesions and assessed by CT scan: Complete response (CR): Disappearance of all target lesions; Partial Response (PR): >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR+PR.
- Progression-free Survival (PFS), [ Time Frame: From first treatment day until objective or symptomatic progression, assessed up to 12 months ]Assessed by Kaplan-Meier survival analysis and 95% confidence intervals will be calculated using Greenwood's formulae.
- Time to Treatment Failure (TTF) [ Time Frame: Time from the first treatment day until disease progression or discontinuation of treatment due to toxicity, assessed up to 12 months ]Assessed by Kaplan-Meier survival analysis and 95% confidence intervals will be calculated using Greenwood's formulae. Time to treatment failure was not reported for this study.
- Overall Survival(OS) [ Time Frame: Time from first treatment day until death, assessed up to 12 months ]Assessed by Kaplan-Meier survival analysis and 95% confidence intervals will be calculated using Greenwood's formulae.
