Trial Identification

Brief Title: Docetaxel Combined With Ketoconazole in Treatment of Breast Cancer

Official Title: Phase II Study of Docetaxel Combined With Ketoconazole in the First-line Treatment of Locally Advanced or Metastatic Breast Cancer Patients With Measurable Primary Breast Tumor

Study ID: NCT00212095

Conditions

Metastatic Breast Cancer

Interventions

docetaxel and ketoconazole

Study Description

Brief Summary: Patients with locally advanced or metastatic breast cancer and with measurable primary breast tumor will be treated with 70mg docetaxel combined with ketoconazole. Serial tumor biopsies and plasma samples will be taken for gene expression and proteomics studies to identify biomarkers that may predict for treatment response.

Detailed Description: We hypothesize that 70mg docetaxel co-administered with ketoconazole would result in similar clinical efficacy as conventional doses of docetaxel (75mg/m2 body surface area) in terms of clinical and pathological response rates in metastatic breast cancer. We further hypothesize that tumor genomic and proteomic changes and serum proteomic changes would correlate with tumor response. We are also looking to correlate drug pharmacokinetics with treatment toxicity, genotype of drug metabolizing enzymes and transporters, and peripheral mononuclear cell gene expression profiles. The primary objectives are to evaluate the clinical response rate of 70mg docetaxel with ketoconazole in metastatic breast cancer, and to evaluate the pathological response rate in the primary tumor following four cycles of docetaxel and ketoconazole.
