A Study of Vorinostat and Tamoxifen in Newly Diagnosed Breast Cancer

May 15, 2013 updated by: Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins

A Multi-Institutional Phase II Study Evaluating Surrogate Biomarkers of Response to Short Term Oral Vorinostat and Tamoxifen in Women With Newly Diagnosed Breast Cancer

This research study is designed to look at the effects of the combination of vorinostat (Suberoylanilide Hydroxamic Acid or Zolinza) and tamoxifen on breast cancer tissue. The investigators will do this by comparing tissues from the original breast biopsy to tissues obtained after taking vorinostat and tamoxifen for 2 weeks.
