Alternate Title

Docetaxel, Estramustine, and Thalidomide in Treating Patients With Androgen-Independent Metastatic Adenocarcinoma of the Prostate

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II Treatment Completed 18 and over NCI NCI-04-C-0132 NCT00083005

Objectives

Primary

1. Determine the prostate-specific antigen response in patients with androgen-independent metastatic adenocarcinoma of the prostate treated with docetaxel, estramustine, and thalidomide.

Secondary

1. Determine the survival duration in patients treated with this regimen.
2. Determine the pharmacokinetics of both docetaxel and thalidomide in patients treated with this regimen.
3. 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.
4. Determine the existence of and quantification of circulating prostate cancer cells in patients before and after treatment with this regimen.
5. Determine genotype, with regard to cytochrome P450 2C19 polymorphism, in patients treated with this regimen.
6. Correlate genotype with pharmacokinetics and efficacy of this regimen in these patients.
7. 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.
8. Determine the toxicity profile of this regimen in these patients.

Survival

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.
