Prostate Cancer Clinical Trial
Gemcitabine and Docetaxel in Treating Patients With Metastatic Prostate Cancer
RATIONALE: Drugs used in chemotherapy, such as gemcitabine 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 gemcitabine together with docetaxel works in treating patients with metastatic prostate cancer.
Determine the objective response rate and toxicity in patients with androgen-independent metastatic prostate cancer treated with gemcitabine hydrochloride and docetaxel.
OUTLINE: This is an open-label study.
Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 followed by docetaxel IV over 60 minutes on day 8. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for at least 5 years.
PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study.
Histologically confirmed adenocarcinoma of the prostate
Androgen-independent metastatic prostate cancer with evidence of clinical, radiographic, or biochemical progression in the setting of castrate levels of testosterone (< 50 mg/dL)
No androgen-independent prostate cancer with a rising prostate-specific antigen (PSA) without clinical or radiographic evidence of metastases
Clinical or radiographic evidence of metastatic disease with a rising PSA measured 2 times at ≥ 1 week interval allowed
Antiandrogen therapy must have been stopped at least 4 weeks (for flutamide) or 6 weeks (for bicalutamide or nilutamide) prior to study entry with evidence of either a rising PSA (from baseline) measured twice at least 2 weeks apart or radiographic evidence of disease progression
Testicular androgen suppression (< 50 mg/dL) must be maintained with either luteinizing-hormone releasing-hormone (LHRH) therapy or bilateral orchiectomy
No clinical evidence of CNS metastases
ECOG performance status 0-2
Absolute neutrophil count ≥ 1,500/mm^3
Platelet count ≥ 100,000/mm^3

Creatinine < 2 mg/dL
No history of severe uncontrolled congestive heart failure (CHF), ventricular dysrhythmias, or severe cardiovascular disease (American Heart Association class III or IV)
Disease-free of prior malignancies for ≥ 5 years, with the exception of curatively treated basal cell or squamous cell carcinoma of the skin or low-grade, low-stage bladder cancer
No active infection or parenteral antibiotics within 7 days of study entry
Fertile patients must use effective contraception
PRIOR CONCURRENT THERAPY:
