Combination Chemotherapy Plus Warfarin in Treating Patients With Prostate Cancer

2014-08-27 03:57:00 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Anticoagulant drugs such as warfarin may reduce the risk of blood clots.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus warfarin in treating patients who have prostate cancer.

Description

OBJECTIVES: I. Determine the safety, efficacy, and durability of docetaxel and estramustine followed by doxorubicin and ketoconazole in patients with high-risk, androgen-independent prostate cancer. II. Determine whether anticoagulation with warfarin can reduce the frequency of thromboembolic complications associated with estramustine in these patients.

OUTLINE: Regimen A: Patients receive oral estramustine 3 times daily on days 1-5 and docetaxel IV over 1 hour on day 3 weekly. Patients also receive oral warfarin daily. Treatment repeats every 4 weeks for a total of 2 courses in the absence of disease progression or unacceptable toxicity. Regimen B: After completion of regimen A, patients receive doxorubicin IV over 30 minutes weekly and oral ketoconazole twice daily. Treatment repeats every 4 weeks for a total of 2 courses in the absence of disease progression or unacceptable toxicity. Patients are followed monthly until disease progression.

PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study within 1 year.

Medical and Biotech [MESH] Definitions

A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.

A family of highly conserved and widely expressed sodium-phosphate cotransporter proteins. They are electrogenic sodium-dependent transporters of phosphate that were originally identified as retroviral receptors in HUMANS and have been described in yeast and many other organisms.

An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.

A nitrogen mustard linked to estradiol, usually as phosphate; used to treat prostatic neoplasms; also has radiation protective properties.

A family of symporters that facilitate sodium-dependent membrane transport of phosphate.
