NCT00416130
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.
NCT00669773
Primary Objectives 1. Validate our previously generated tumor gene expression and proteomic profiles in this independent sample to determine the predictive power to distinguish good from poor clinical and pathological responders to adriamycin or docetaxel. 2. Validate our previously generated plasma proteomic profiles in this independent sample to determine the predictive power to distinguish good from poor clinical and pathological responders to adriamycin and docetaxel. Secondary objectives 1. To correlate adriamycin and docetaxel pharmacokinetics with 1. Genetic polymorphisms of drug metabolizing enzymes and transporters, including MDR-1, Cyp3A, GSTs, and the nuclear receptors. 2. Drug toxicity and tumor response. 3. Peripheral mononuclear cell gene expression profiles 2. To study ondansetron pharmacokinetics and correlate that with genetic polymorphisms.
