Condition(s) targeted: Prostate Cancer

Intervention: docetaxel (Drug); leuprolide acetate (Drug); radiation therapy (Radiation)

Phase: Phase 1/Phase 2

Status: Completed

Summary

RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as leuprolide, may lessen the amount of androgens made by the body. Radiation therapy uses high energy x-rays to kill tumor cells. Giving docetaxel together with androgen ablation therapy and external-beam radiation therapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of docetaxel when given together with androgen ablation therapy and external-beam radiation therapy and to see how well they work in treating patients with high-risk localized prostate cancer.

Clinical Details

Official title: A Phase I/II Study of Concurrent Weekly Docetaxel (Taxotere), Androgen Ablation, and Adaptive External Beam Radiotherapy for Localized High-Risk Adenocarcinoma of the Prostate

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

Primary outcome:

Progression-free survival

Survival

Detailed description: OBJECTIVES: Primary

- Determine the dose-limiting toxicity and maximum tolerated dose of docetaxel when

administered in combination with androgen ablation therapy and adaptive external-beam radiotherapy in patients with high-risk localized adenocarcinoma of the prostate. Secondary

- Determine the 2-year biochemical progression-free survival of patients treated with

this regimen. OUTLINE: This is a multicenter, open-label, dose-escalation study of docetaxel.

- Androgen ablation therapy: Patients receive leuprolide acetate or other luteinizing

hormone-releasing hormone agonist beginning 2-3 months prior to the start of chemoradiotherapy and continuing for up to 2 years.

- Chemoradiotherapy: Patients receive docetaxel IV over 1 hour on day 1 and high-dose

external-beam radiotherapy on days 1-5. Treatment repeats every 7 days for 8 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of docetaxel until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. After completion of study treatment, patients are followed every 3 months.
