Description/
Intervention:
The goal of this clinical research study is to learn if giving dendritic cells
with PANVAC-V and PANVAC-F is more effective than PANVAC-V and PANVAC-F alone
in keeping cancer from coming back after surgery and chemotherapy.
.
Study Objectives / Outcomes
Primary Objective: Choose between two immunization strategies, dendritic cells (DC) infected with PANVAC-V followed by dendritic cells infected with PANVAC-F or PANVAC-V followed by PANVAC-F, in terms of which is associated with a better rate of recurrence-free survival at 2 years following hepatic or pulmonary metastasis resection and adjuvant chemotherapy in patients with colorectal cancer (CRC).
    Secondary Objective: Describe the rate and magnitude of immune response, as determined by the ELISpot assay for each of the two immunization strategies. In those with positive immunologic responses, characterize the response further by tetramer analysis, intracellular cytokine release, cytotoxicity assays, and proteomic analysis.

    Enrollment Eligibility
    If you do not meet the enrollment eligibility, there may be other treatment options for you. Please Contact the Referral Office for more information.

    Inclusion Criteria:1) Histologically confirmed hepatic or pulmonary metastases of colorectal adenocarcinoma, resected with curative intent. Since virtually all colorectal cancers express CEA, no additional stains will be required. Subjects in whom one or more lesions is resected and one or more is ablated will be permitted to enroll as long as the ablation is thought to have destroyed all gross tumor. Subjects must have no evidence of disease at the time of study enrollment.

    2) Patients who have had repeated resections of hepatic or pulmonary metastatic disease or who have had resections of extrahepatic metastases prior to resection of the hepatic metastases are eligible if at the time of the most recent hepatic metastasis resection, all disease was resected and/or ablated according to the operative report.

    3) Must have had a minimum of 2 months of peri-operative systemic chemotherapy (includes pre-operative, post-operative or both) chosen at the discretion of their physicians. Patients may be screened starting any time after their chemotherapy is completed, but may not start the treatment related procedures until at least 1 month after completion of chemotherapy or resection whichever, comes later.

    4) Karnofsky performance status >/= 70%.

    5) Estimated life expectancy >/= 6 months.

    6) Subjects must be equal to or greater than 18 years.

    7) Adequate hematologic function with: Hemoglobin >/= 8.5 mg/dL (transfusion or Erythropoietin acceptable); Platelets >/= 75,000/mm^3.

    8) Adequate renal and hepatic function with: Serum creatinine </= 1.5 mg/dL or a creatinine clearance of greater than 60 mL/min; Bilirubin </= 2.0 mg/dL.

    9) Ability to provide signed informed consent that fulfills Institutional Review Board guidelines.

    Exclusion Criteria:1) Subjects with gross residual disease after surgery as determined by their surgeon.

    2) Subjects with concurrent chemotherapy, radiation therapy, or other immunotherapy.

    3) Subjects with a history of autoimmune disease such as, but not restricted to, inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis, scleroderma, or multiple sclerosis.

    4) Subjects with any documented inflammatory bowel condition (such as, but not limited to, active infectious enteritis, inflammatory bowel disease, or eosinophilic enteritis).

    5) Subjects with serious intercurrent chronic or acute illness such as pulmonary (asthma or COPD) or cardiac (NYHA class III or IV) or hepatic disease or other illness considered by the P.I. to constitute an unwarranted high risk for investigational drug treatment.

    6) Subject with medical or psychological impediment to probable compliance with the protocol.

    7) Second malignancy in the prior 5 years other than non-melanoma skin cancer, or controlled superficial bladder cancer or treated cervical carcinoma in situ.

    8) Presence of an active acute or chronic infection, including urinary tract infection, HIV or viral hepatitis (as determined by HBsAg and Hepatitis C serology).

    9) Subjects on steroid therapy (or other immunosuppressives such as azathioprine or cyclosporine A) are excluded on the basis of potential immune suppression. Subjects must have had 6 weeks of discontinuation of any steroid therapy prior to enrollment.

    10) Subjects with egg allergies or allergies to any component of the vaccine should be excluded from the protocol.

    11) Pregnant and nursing women should be excluded from the protocol since this research may have unknown and harmful effects on an unborn child or on young children. If the subject is sexually active, the subject must agree to use a medically acceptable form of birth control in order to be in this study and continue birth control for one month after the last vaccination. It is not known whether the treatment used in this study could affect the sperm and could potentially harm a child that may be fathered while on this study.

    12) Subjects with prior or concurrent extensive eczema or acute, chronic, or exfoliative skin disorders (e.g., extensive psoriasis, burns, impetigo, or disseminated zoster, varicella zoster, severe acne, or other open rashes or wounds)

    13) Subjects must be able to avoid household contact with: persons with active, or a history of, eczema or other acute or chronic skin conditions, pregnant or nursing women, children under age 5, or immunosuppressed or immunodeficient persons. Unable to avoid close contact or household contact with the following high-risk individuals for 3 weeks after the DAY 0 vaccination: Children under the age of 5; Pregnant or nursing women; Individuals with prior or concurrent extensive eczema or other eczematoid skin disorders; Immunocompromised individuals (by disease or therapy) such as those with AIDS;

    14) Subjects with a history of allergy or untoward reaction to prior vaccinia (smallpox) vaccination.

    15) Allergy or untoward reaction to prior GM-CSF administration.

    16) Active infection within 72 hours of vaccination.

    17) Subjects with a history of myocardial infarction or cerebrovascular accident within one year of registration to the study, and/or unstable or uncontrolled angina.
