Vaccine Therapy in Treating Patients With Metastatic, Progressive Prostate Cancer
Prostate Cancer

About this trial
This is an interventional treatment trial for Prostate Cancer focused on measuring recurrent prostate cancer, stage IV prostate cancer
Eligibility Criteria
DISEASE CHARACTERISTICS:
Histologically confirmed prostate cancer with evidence of progressive disease despite hormonal therapy (i.e., hormone-refractory prostate cancer)
- Metastatic disease
Progressive disease defined by any of the following:
- New bone lesion on bone scan
- Progression of nodal or soft tissue as evidenced by standard radiographic methods, i.e., CT scan or MRI
- A 50% increase in PSA level from the nadir PSA level confirmed twice and measured at least 2 weeks apart, with stable and measurable disease
- Castrate serum levels of testosterone < 50 ng/dL
If patient was receiving anti-androgen therapy, in addition to luteinizing hormone-releasing hormone (LHRH) agonist therapy, the evidence of progressive disease should persist after a trial of anti-androgen withdrawal
- Treatment with LHRH agonist to maintain androgen ablation must continue throughout this trial
- Baseline PSA ≥ 10 ng/mL
All patients with androgen-independent prostate cancer and matched HLA typing are eligible for vaccination regardless of initial NY-ESO-1 expression status
- Patients must be typed for HLA-DR4, DR13, DP4, or HLA-A2 haplotypes
- No active brain metastases
PATIENT CHARACTERISTICS:
- Zubrod performance status 0-2
- Life expectancy ≥ 12 weeks
- ANC ≥ 1,500/mm³
- Hemoglobin ≥ 10 mg/dL
- Platelet count ≥ 100,000/mm³
- Bilirubin ≤ 1.5 mg/dL
- SGPT ≤ 3 times upper limit of normal
- Serum creatinine ≤ 2 mg/dL
- Wiling to be followed at Baylor College of Medicine
- No serious intercurrent medical illness
- No history of primary or secondary immunodeficiency
- No active systemic infection
- No known hepatitis B surface antigen, hepatitis C, or HIV antibody positivity
- No history of cardiac arrhythmia or ischemic heart disease
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- At least 6 weeks since prior immunotherapy (including anti-androgen therapy) and recovered
- More than 28 days since prior chemotherapy
- No concurrent immunosuppressive drugs such as systemic corticosteroids
