Paclitaxel and Carboplatin in Treating Patients With Metastatic Prostate Cancer That Has Not Responded to Hormone Therapy
A Phase II Trial of Paclitaxel and Carboplatin in the Treatment of Hormone-Refractory Prostate Cancer (HRPC)
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.
PURPOSE: Phase II trial to study the effectiveness of combining paclitaxel with carboplatin in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.

Detailed Description
OBJECTIVES:
- Determine the prostate-specific antigen (PSA) response rate and time to PSA progression in patients with metastatic hormone-refractory prostate cancer treated with paclitaxel and carboplatin.
- Determine the objective response rate, time to measurable or evaluable disease progression, and overall survival in patients treated with this regimen.
- Determine the safety and toxicity of this regimen in these patients.
OUTLINE: This is an open-label study.
Patients receive paclitaxel IV on days 1, 8, and 15 and carboplatin IV on day 1. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed every 4 weeks for 12 weeks and then every 2 months thereafter.
PROJECTED ACCRUAL: Approximately 60 patients will be accrued for this study.

Genders Eligible for Study
Description
Inclusion Criteria:
- Patients must be informed of investigational nature of the study and written informed consent must be obtained prior to study entry
- Patients >18 years of age
- Patients with a histologic diagnosis of adenocarcinoma of the prostate
- Patients must have metastatic disease with progression despite androgen ablation. Patients who have not undergone orchiectomy must continue LHRH analogues. For patients receiving LHRH analogues their testosterone level must be < 50ng/dL
- Patients with bidimensionally measurable disease or bone metastases that is not progressive but who have a rising PSA are eligible
- Patients with an ECOG performance status <2
- Patients must have discontinued flutamide or nilutamide at least 4 weeks prior to the first day of treatment with evidence of progressive disease. Patients must have discontinued bicalutamide at least 6 weeks prior to registration with evidence of progressive disease
Patients with adequate hematological, renal, and hepatic function as defined by the following required laboratory values:
- While blood cell count: > 3,000/mm3
- Absolute granulocyte count: > 1,500/mm3
- Platelets: > 100,000/mm3
- Hemoglobin: > 8.5 g/dL
- Total bilirubin: < 1.5 mg/dL
- Serum creatinine: < 2.5 mg/dL
- AST or ALT: < 2.5 x institutional upper limit of normal
- Patients may have received prior radiation therapy, provided at least 4 weeks have elapsed since the conclusion of radiation therapy
Exclusion Criteria:
- Patients with biochemical only progression
- Patients who have received any prior chemotherapy for cancer of the prostate
- Patients who received antiandrogen therapy within 4 weeks prior to the first day of treatment after cessation of flutamide or nilutamide, and or within 6 weeks prior to registration after cessation of bicalutamide
- Patients receiving concomitant chemotherapy, biologic therapy, or radiation therapy
- Patients who have received Strontium 89 or other radioisotope therapies
- Patients with decreasing PSA levels following antiandrogen withdrawal
- Patients with > grade 1 peripheral sensory or motor neuropathy
- Patients with known carcinomatous meningitis or brain metastases are excluded
- Patients with past or current histories of neoplasm other than entry diagnosis except for in-situ carcinoma of any site, non-melanoma skin cancer, or other malignancy treated by surgery or radiation with a disease-free survival longer than 5 years
- Patients who have undergone major surgery < 3 weeks prior to registration, except for biopsy or placement of a venous access device. Patients must have fully recovered from all effects of any prior surgery
- Patients with histories of serious cardiac disease not adequately controlled: documented myocardial infarction within the last 6 months preceding registration, congestive heart failure, unstable angina, valvular disease with documented ventricular compromise, uncontrolled hypertension, arrhythmia uncontrolled by medication, clinically significant pericardial effusion
- Patients with active serious infections or other serious underlying medical conditions that would otherwise impair their ability to receive protocol treatments
- Patients with dementia or significantly altered mental status that would prohibit the understanding and/or giving of informed consent
- Patients receiving other investigational therapy
- Use of any investigational agent within 30 days of first day of treatment and use of Ketoconazole, hydrocortisone, glucocorticoids, or megace within 30 days of first day of treatment or other concomitant medications

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Prostate-specific Antigen (PSA) Response Rate
Time Frame: Evaluated every 28 days during Treatment Period. Number of completed cycles among 58 treated patients range from 1 to 24 cycles with a median of 4.5 cycles. one cycle = 28 days.
|
PSA response is defined as a decline from the baseline value of >=50% confirmed by a second PSA value 4 or more weeks later.
|
Evaluated every 28 days during Treatment Period. Number of completed cycles among 58 treated patients range from 1 to 24 cycles with a median of 4.5 cycles. one cycle = 28 days.
|
Time to PSA Progression
Time Frame: Evaluated every 28 days during Treatment Period
|
In patients whose PSA has not decreased, progressive disease is a 25% increase over the baseline value and an increase in the absolute value PSA level by >=5ng/ml, confirmed by a second value at >=4 week intervals.
In patients whose PSA has decreased but has not reached response criteria, progressive disease is defined as an increase in PSA by 25% over the nadir, provided that the increase is >=5ng/ml and is confirmed by a second value at >=4 week intervals.

Evaluated every 28 days during Treatment Period

Measure Description |
Time Frame |
---|---|---|
Objective Response Rate
Time Frame: Evaluated every 12 weeks during Treatment Period
|
