Résumé
Date de début de l'étude : 1 mars 2004
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: Primary * Determine the prostate-specific antigen response in patients with androgen-independent metastatic adenocarcinoma of the prostate treated with docetaxel, estramustine, and thalidomide. Secondary * Determine the survival duration in patients treated with this regimen. * Determine the pharmacokinetics of both docetaxel and thalidomide in patients treated with this regimen. * Determine whether any pharmacodynamic relationships exist between plasma concentrations of docetaxel and/or thalidomide and clinical activity or toxicity of this regimen in these patients. * Determine the existence of and quantification of circulating prostate cancer cells in patients before and after treatment with this regimen. * Determine genotype, with regard to cytochrome P450 2C19 polymorphism, in patients treated with this regimen. * Correlate genotype with pharmacokinetics and efficacy of this regimen in these patients. * Determine the changes in molecular markers of angiogenesis (including, but not limited to, serum and urine vascular endothelial growth factor) in patients before and after treatment with this regimen. * Determine the toxicity profile of this regimen in these patients. OUTLINE: This is an open-label study. Patients receive docetaxel IV over 30 minutes on days 2, 9, and 16, oral thalidomide once daily on days 1-28, and oral estramustine three times daily on days 1-3, 8-10, and 15-17. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Patients are followed for survival. PROJECTED ACCRUAL: A total of 33-60 patients will be accrued for this study within 11-20 months.
