A Multi-Institutional Double-Blind Phase II Study Evaluating Response and Surrogate Biomarkers to Carboplatin and Nab-Paclitaxel (CP) With or Without Vorinostat as Preoperative Chemotherapy in HER2-negative Primary Operable Breast Cancer
RATIONALE: Drugs used in chemotherapy, such as carboplatin and paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vorinostat may also help carboplatin and paclitaxel albumin-stabilized nanoparticle formulation work better by making tumor cells more sensitive to the drugs. Giving chemotherapy with or without vorinostat before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This randomized phase II trial is studying how well giving carboplatin together with paclitaxel albumin-stabilized nanoparticle formulation works with or without vorinostat in treating women with breast cancer that can be removed by surgery.

Primary outcomes
- Pathological Complete Response (pCR) Rate — Time of breast cancer surgery
The primary end point was pCR, defined as no viable invasive cancer in breast and axilla. All other cases were defined as non-pCR. The pCR rate was determined in each arm separately by performing an intent-to-treat (ITT) analysis of all randomized patients. Patients with unknown pCR status were considered non-responders. Computation of associated 90% confidence intervals did not account for the sequential design.
