Brief Summary

This study will evaluate the side effects of a fixed dose of vaccine and GM-CSF with increasing doses of anti-CTLA-4 antibody in patients with advanced prostate cancer. The vaccine consists of a "priming vaccine" called PROSTVAC/TRICOM, made from vaccinia virus, and a "boosting vaccine" called PROSTVAC-F/TRICOM, made from fowlpox virus. GM-CSF is a chemical that boosts the immune system, and anti-CTLA-4 antibody is a protein that may improve anti-tumor activity and the response to the vaccines. DNA is inserted into the priming and boosting vaccine viruses to cause production of proteins that enhance immune activity and also to produce prostate specific antigen (PSA)-a protein that is normally produced by the patient's tumor cells. Patients 18 years of age and older with androgen-insensitive prostate cancer that has spread beyond the original site may be eligible for this 7-month study. Candidates must have disease that has worsened despite treatments with hormones and up to one chemotherapy regimen. Their tumor must produce PSA, and they must have no history of allergy to eggs or egg products Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram, pathological confirmation of the diagnosis and presence of the PSA marker, chest x-rays, imaging studies to assess the extent of tumor, and, if clinically indicated, a cardiologic evaluation. Participants receive the priming vaccination on study day 1. After 2 weeks and then again every 4 weeks while on the study, they receive a boosting vaccine. All vaccines are injected under the skin. On the day of each vaccination and daily for the next 3 days, patients receive an injection of GM-CSF to increase the number of immune cells at the vaccination site. On the day of the first six boosting vaccinations, they receive anti-CTLA-4 antibody as an infusion through a vein over 90 minutes. Patients are monitored for safety and treatment response with the following tests and procedures:

• Blood and urine tests monthly, or more often if needed, to monitor liver, kidney, and other organ function.
• Imaging studies to assess the tumor before starting treatment, again around study days 99 and 183, and then every 3 months after that while on study.
• Apheresis (a procedure for collecting immune cells called lymphocytes) to measure the immune response to treatment. Apheresis is done three times: before starting the study and again around study days 99 and 183. For this procedure, blood is collected through a needle in an arm vein. The blood circulates through a machine that separates it into its components by spinning, and the lymphocytes are extracted. The rest of the blood is returned to the patient through the same needle. This will only be done in participants who have the tissue marker HLA-A2 (about 50% of patients). Patients whose disease responds to treatment and who do not develop severe side effects may continue treatment beyond the initial 7-month study period on vaccine alone (without the antibody). After treatment is completed, patients are monitored for up to 15 years. This includes a medical history and physical examination for 5 years following the last vaccination. Information beyond 5 years is collected once a year by telephone.

Outcome Measures

Primary Outcomes (1)

• To determine the safety and tolerability of a combination of a fixed dose of vaccine and anti-CTLA4, which will be dose escalated.

Secondary Outcomes (1)

• To evaluate immunologic response (as measured by an increase in PSA specific T-cells measured by ELISPOT in HLA-A2+ patients), and clinical response (as measured by RECIST and PSA consensus criteria).

• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• A. Histopathological documentation of prostate cancer confirmed in the Laboratory of Pathology at the: NIH Clinical Center, National Institutes of Health (NIH), the National Naval Medical Center, or Walter Reed Army Medical Center prior to starting this study. If no pathologic specimen is available, patients may enroll with a pathologist's report showing a histologic diagnosis of prostate cancer and a clinical course consistent with the disease.
• B. Must have metastatic androgen insensitive prostate cancer with no bone pain requiring narcotics and have had no prior chemotherapy.
• C. Life expectancy greater than or equal to 6 months.
• D. ECOG performance status of 0-1.
• E. No systemic steroid or steroid eye drop use within 2 weeks prior to initiation of experimental therapy.
• F. Hematological eligibility parameters
• Granulocyte count greater than or equal to1,500/mm(3)
• Platelet count greater than or equal to100,000/mm(3)
• Hgb greater than or equal to 9 Gm/dL
• Lymphocyte count greater than or equal to 500/mm(3).
• G. Biochemical eligibility parameters (within 16 days of starting therapy)
• Hepatic function: Bilirubin less than or equal to 1.5 mg/dl (OR in patients with Gilbert's syndrome, a total bilirubin less than or equal to 3.0 mg/dL), AST and ALT less than or equal to 2.5 times upper limit of normal
• H. No other active malignancies within the past 12 months (with the exception of non-melanoma skin cancers or carcinoma in situ of the bladder) or life threatening illnesses.
• I. Willing to travel to the NIH for follow-up visits.
• J. 18 years of age or greater.

You may not qualify if:

• A. Patients should have no evidence of being immunocompromised as listed below.
• Human immunodeficiency virus positivity due to the potential for decreased tolerance and may be at risk for severe side effects.
• Hepatitis B or C positivity
• Concurrent use of topical steroids (including steroid eye drops) or systemic steroids. Nasal or inhaled steroid use is permitted
• B.Patients should have no autoimmune diseases that have required treatment such as, Addison's disease, Hashimoto's thyroiditis, or systemic lupus erythematous, Sjogren syndrome, scleroderma, Goodpasture syndrome, and active Grave's disease. Also excluded are patients with autoimmune hemolytic anemia, ulcerative and hemorrhagic colitis, endocrine disorders (e.g., thyroiditis, hyperthyroidism, hypothyroidism, autoimmune hypophysitis/hypopituitarism, and adrenal insufficiency), sarcoid granuloma, myasthenia gravis, polymyositis, and Guillain-Barre syndrome. Patients with a history of autoimmunity that has not required systemic immunosuppressive therapy or does not threaten vital organ function including CNS, heart, lungs, kidneys, skin, and GI tract will be allowed.
• C. History of allergy or untoward reaction to prior vaccination with vaccinia virus or to any component of the vaccinia vaccine regimen.
• D. Do not administer the recombinant vaccinia vaccine if the recipient, or for at least three weeks after vaccination, their close household contacts (close household contacts are those who share housing or have close physical contact) are: persons with active or a history of eczema or other eczematoid skin disorders; those with other acute, chronic or exfoliative skin conditions (e.g., atopic dermatitis, burns, impetigo, varicella zoster, severe acne, or other open rashes or wounds) until condition resolves; pregnant or nursing women; children 3 years of age and under; and immunodeficient or immunosuppressed persons (by disease or therapy), including HIV infection.
• E. Serious intercurrent medical illness (e.g., one that requires treatment) which would interfere with the ability of the patient to carry out the treatment program, including, but not limited to, inflammatory bowel disease, Crohn's disease, ulcerative colitis, or active diverticulitis.
• F. Patients with cardiac disease that have fatigue, palpitation, dyspnea or angina with ordinary physical activity (New York Heart Association class 2 or greater) are not eligible.
