Summary

Background: * Many cancers produce two proteins, carcinoembryonic antigen (CEA) and mucin-1 (MUC-1). * The PANVAC-V (PANVAC vaccinia) priming vaccine and PANVAC-F (PANVAC fowlpox) boosting vaccine contain human genes that cause production of CEA and MUC-1, which can be used as a target for the immune system to attack the cancer. The vaccines also contain genes that cause production of other proteins that enhance immune activity. * Sargramostim is a protein that boosts the immune system. Objectives: * To evaluate the safety and effectiveness of PANVAC-V and PANVAC-F in patients with advanced cancer. * To document the immune response to the vaccines and any anti-tumor responses that may occur. Eligibility: Patients 18 years of age and older with advanced cancer whose tumors produce CEA or MUC-1 protein Design: * This trial has three cohorts: the first cohort includes 10 patients with advanced colorectal cancer and 10 to 15 patients with any advanced non-colorectal cancer that produces either EA or mitochondrial Ca2+ uniporter 1 (MCU-1); the second cohort includes 12 patients with advanced breast cancer and the third cohort includes 14 patients with advanced ovarian cancer. * All patients receive PANVAC-V on study day 1, followed by PANVAC-F on days 15, 29 and 43 then every 28 days for up to 12 vaccines followed by every 3 months until disease progression or toxicity. The vaccines are given by injection under the skin. Sargramostim is injected at the vaccination site on the day of each vaccination and for the next 3 days following vaccination. * Patients whose scans show that their disease has progressed, but who are otherwise clinically stable may revert back to monthly injections. * Patients undergo apheresis to collect white blood cells (lymphocytes) on day 1 and day 71 of the study to measure the immune response to the treatment. Blood is collected through a needle placed in one arm and directed through a cell separator machine where the lymphocytes are extracted. The rest of the blood components are returned to the patient through the same needle. * Patients are monitored with frequent blood tests and periodic imaging tests (scans) to monitor for safety and the response to treatment.

Eligibility Criteria

  • INCLUSION CRITERIA:

A. Histologically confirmed carcinoma that for patients in the first cohort (colorectal and non-colorectal cancer) is carcinoembryonic antigen (CEA) or mucin-1 (MUC-1) positive. Tumor that has been shown to express CEA or MUC-1 (greater than or equal to 20 % of cells) by immunohistochemical techniques or patients that have had an elevated serum CEA (greater than 5 microgram/L) at any point during their disease course. For patients in the ovarian and breast cancer cohorts, as greater than 95% of these express MUC-1 or CEA, we will not require staining prior to coming onto trial.

B. Patients must have completed at least one fluorouracil (5-FU) containing chemotherapy regimen (e.g. 5-FU/leucovorin (LV) with or without either irinotecan or oxaliplatin) for the colorectal cancer arm, or either failed or not be a candidate for therapy of proven efficacy for non-colorectal, breast, or ovarian cancer.

C. 18 years of age or greater.

D. All patients enrolled on the colorectal/non-colorectal cohort with colorectal adenocarcinoma cohort must be human leukocyte antigen A2 (HLA-A2) positive.

E. At least 10 patients enrolled on the colorectal/non-colorectal cohort with non-colorectal adenocarcinoma cohort must be HLA-A2 positive.

F. Patients in the breast cohort and the ovarian cohorts are not required to be HLA-A2 positive.

G. For the colorectal and non-colorectal cancer cohort, patients will be required to have: metastatic disease (measurable or evaluable), metastatic disease documented by biopsy but not evaluable by imaging (e.g. small volume peritoneal disease), and patients with surgically resected metastatic disease at high risk of relapse. For the ovarian cohort and the breast cancer cohort, patients will be required to have evaluable disease.

H. Able to understand and give informed consent.

I. Able to avoid close household contact (close household contacts are those who share housing or have close physical contact) for at least three weeks after recombinant vaccinia vaccination with 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 human immunodeficiency virus (HIV) infection.

J. Eastern Oncology Cooperative Group (ECOG) performance status of 0 - 1.

K. Serum creatinine not above the institution limits of normal, and aspartate aminotransferase (AST) less than or equal to twice the upper limits of normal OR creatinine clearance on a 24 hour urine collection of greater than or equal to 60 mL/min.

L. Total bilirubin within the institution limits of normal OR patients with Gilbert's syndrome, a total bilirubin less than or equal to 3.0

M. Recovered completely from any reversible toxicity associated with recent therapy. Typically this is 3-4 weeks for patients who most recently received cytotoxic therapy except for the nitrosoureas and mitomycin C for which 6 weeks is needed for recovery.

N. Hematological eligibility parameters (within 16 days of starting therapy):

  • Granulocyte count greater than or equal to 1,500/mm(3)
  • Platelet count greater than or equal to 100,000/mm(3)
  • Hemoglobin (Hgb) greater than or equal to 10 Gm/dL

O. Prior immune therapy with related vaccinia and fowlpox vaccines or antigen-specific peptides is allowed.

P. Men and women must agree to use effective birth control or abstinence during and for a period of 4 months after the last vaccination therapy.

Q. Patients with prostate cancer must continue to receive gonadotropin-releasing hormone (GnRH) agonist therapy (unless orchiectomy has been done).

R. Patients should appear clinically stable (in the opinion of the principal investigator) to complete the full 3 mont
