Condition(s) targeted: Prostate Cancer

Intervention: capecitabine (Drug); docetaxel (Drug)

Phase: Phase 2

Status: Completed

Summary

RATIONALE: Drugs used in chemotherapy, such as capecitabine and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving capecitabine together with docetaxel works in treating patients with metastatic prostate cancer.

Clinical Details

Official title: Phase II Trial of Capecitabine (Xeloda) and Weekly Docetaxel (Taxotere) in Metastatic Androgen Independent Prostate Carcinoma

Study design: Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Response rate by RECIST criteria after every 2 courses

Secondary outcome:

Toxicity at 30 days after last treatment

Progression-free survival

Time to treatment failure

Overall survival

Effect of treatment on biological correlates (thymidine phosphorylase, dihydropyrimidine dehydrogenase, thymidylate synthase)

Detailed description: OBJECTIVES: Primary

- Determine the response rate in patients with androgen-independent metastatic

adenocarcinoma of the prostate treated with capecitabine and docetaxel. Secondary

- Determine the toxicity of this regimen in these patients.

- Determine the progression-free survival, time to treatment failure, and overall

survival of patients treated with this regimen. OUTLINE: This is a multicenter study. Patients receive docetaxel IV over 30 minutes on days 1, 8, and 15 and oral capecitabine twice daily on days 5-18. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive 2 additional courses of therapy beyond CR After completion of study treatment, patients are followed periodically for survival. PROJECTED ACCRUAL: A total of 28 patients will be accrued for this study.
