Clinical Trial of SAHA in Patients With Breast Cancer

Summary

Purpose: * evaluate the safety of Vorinostat. * evaluate the effectiveness of Vorinostat in treating breast cancer * evaluate how the study subject's body reacts to Vorinostat, how these reactions relate to the subject's genes, and whether protein changes in the subject blood may be used to predict how the subject's cancer will respond to Vorinostat We hypothesize that Vorinostat, as a novel class of anti-cancer agents, may induce response in patients with recurrent or metastatic breast cancer who have been previously treated with anthracyclines and taxanes. In addition, we hypothesize that serum Vorinostat levels may correlate with clinical response and toxicities, and that Vorinostat may induce unique protein changes in the plasma in responding patients, and that these proteins may in turn be used as predictive biomarkers for treatment response.
