Primary Eligibility:
- Histopathological documentation of prostate cancer confirmed in the NIH Laboratory of Pathology
- Must have non-metastatic androgen-insensitive prostate cancer
- Prior treatment with bicalutamide or nilutamide
- Rising PSA on prior antiandrogen therapy and no evidence of metastatic disease on CT scan or bone scan (rising PSA is defined as two consecutively rising PSA levels, separated by ≥ 1 month apart, with the last measurement > 1 ng/ml)
- Patients must recover from prior therapy and show evidence of rising PSA
- Patients who have received prior flutamide therapy for > 1 month (prior to enrolling on study) are not eligible
- Life expectancy ≥ 6 months
- ECOG performance status of 0–1
- Granulocyte count ≥ 1,500/mm3; platelet count ≥ 100,000/mm3; hemoglobin ≥ 9 g/dL; lymphocyte count ≥ 500/mm3; bilirubin < 1.5 mg/dl; AST and ALT < 2.5 x upper limit of normal (ULN)
- Patients must have < grade 2 proteinuria (unless the cause is determined not to be renal)
- Creatinine clearance ≥ 60 mL/min with 24-hour urine collection
- HIV negative, hepatitis B and C negative
- No other active malignancies within the past 5 years (with the exception of non-melanoma skin cancers or carcinoma in situ of the bladder) or life-threatening illnesses
- Recovered from all prior therapy
- No autoimmune diseases
- No serious intercurrent medical illness that would preclude study participation
- No history of heart disease; no history of pulmonary disease
- No CNS involvement or history of seizures, encephalitis, or multiple sclerosis
- Patients with prior splenectomy are not eligible
- No hypersensitivity to egg products
Treatment Plan:
Patients will be randomized on a 1:1 basis to Arm I (flutamide alone) or Arm II (flutamide + vaccine).
Arm I
- Patients receive flutamide 250 mg orally 3 x daily (TID) beginning on Day 1
Arm II
- Flutamide 250 mg orally TID beginning on Day 1
- PROSTVAC-V/TRICOM (vaccinia) subcutaneously on Day 1 of the first cycle only
- Followed by monthly (every 4 weeks) boosting vaccinations with PROSTVAC-F/TRICOM (fowlpox) subcutaneously on Day 1 of each cycle
- Sargramostim 100 mcg subcutaneously will be given at the vaccine site for 4 consecutive days starting on Day 1 of each vaccine cycle
- Treatment repeats every 28 days
| After 3 months of therapy, patients receiving the flutamide alone (Arm I) may cross over to receive vaccine if they develop a rising PSA and scans are without metastatic disease |
