INCLUSION CRITERIA:
Patients must have histopathological documentation of prostate cancer confirmed in the Laboratory of Pathology, CCR, NCI, or NNMC prior to starting this study. If no pathologic specimen is available to the NCI or NNMC, patients may enroll with a pathologist's report showing a histologic diagnosis of prostate cancer and a clinical course consistent with the disease.
Patients must have androgen insensitive metastatic prostate cancer. Progression must be documented by at least one of the following parameters.
a. All patients must have received standard of care (hormonal) treatment before entering the trial.
b. All patients will have received and progressed on hormonal therapy for metastatic prostate carcinoma.
c. All subjects must have objective evidence of metastasis or relapsing local disease to be eligible for this Phase I trial; therefore, they must have a rising PSA and at least one of the following: positive bone scan, palpable disease, or positive imaging studies, as defined below.
i. Two consecutively rising PSA levels, separated by at least 1 week, with at least one measurement that is 50% above the
nadir reached after the last therapeutic maneuver (as long as the last measurement is 5 ng/ml or greater), and
ii. At least one lesion consistent with metastatic cancer on Technetium (Tc)-99 whole body scintigraphy, and/or
iii. Soft-tissue metastases as measured by appropriate modalities (i.e., imaging, palpation).
Patients must have a life expectancy of more than 6 months.
Patients must have a performance status of 0 to 2 according to the ECOG criteria.
Patients must have recovered from any acute toxicity related to prior therapy, including surgery, and radiation (treatment must have been completed at least 4 weeks prior to being eligible for the study). Patients who are responding to hormonal therapy are not eligible until evidence of disease progression.
Hematological eligibility parameters (within 16 days of starting therapy):
Granulocyte count greater than or equal to 1,500/mm3
Platelet count greater than or equal to 100,000/mm3
Lymphocyte count greater than or equal to 500/mm3
Hgb greater than or equal to10 Gm/dL
Biochemical eligibility parameters (within 16 days of starting therapy):
a. A 24-hour urine collection for baseline to measure creatinine clearance, protein and electrolytes. CrCl greater than 60, less than 1000 milligrams per 24 hours, less than or equal to Grade 1 (NCI-CTC version 2.0) proteinuria, Grade 0 hematuria, and no abnormal sediment. Grade 0 creatinine. Patients must have serum creatinine within normal limits.
Any abnormalities in the sediment or the presence of hematuria without a likely underlying cause should prompt the investigator to consider an evaluation by a nephrologist for evidence of underlying renal pathology. Patients may be eligible if the underlying cause of the abnormality is determined to be non-renal.
b. Hepatic function: Bilirubin less than 1.5 mg/dl, AST and ALT less than 2.5 times upper limit of normal.
c. Patients must be test negative for HIV, Hepatitis B and C.
Patients must not have other active malignancies within the past 2 years (with the exception of non-melanoma skin cancers or carcinoma in situ of the bladder) or life threatening illnesses.
Patients must be willing to travel to the NIH for follow-up visits.
Patients must be greater than or equal to 18 years of age.
All patients who have received prior vaccination with vaccinia virus (for smallpox immunization) must not have a history of allergy or untoward reaction to the vaccine. Since vaccinia immunoglobulin (VIG) is available from the CDC, prior vaccinia vaccination as a safety precaution is no longer required.
Patients must understand and sign informed consent that explains the neoplastic nature of their disease, the procedures to be followed, the experimental nature of the treatment, alternative treatments, potential risks and toxicities, and the voluntary nature of participation.
For Stage 2 of this study only, patients must not have received the following chemotherapeutic agents for cancer within 3 years of enrolling on study: docetaxel, paclitaxel, doxorubicin, cisplatinum, carboplatinum, mitoxantrone, estramustine, cyclophosphamide, irinotecan, topotecan. Patients must not have received prior PSA vaccine therapy.
Patients will tested for HLA-A2; however, the results of this test will not affect entry onto Stage 1 of this study. This test may be drawn by the patient's referring physician at the time of referral (see Appendix C, HLA-typing consent). This consent will be mailed to the patient and discussed with patient. The signed consent will be signed with a witness, then mailed to the assigned research nurse at the NIH Clinical Center. These patients must have measurable disease on CT, MRI, or bone scan.
The effects of the study agents used in this protocol on the developing human fetus are unknown. For this reason men must agree to use adequate contraception prior to study entry and for the duration of study participation.
