Official Title: A Phase I Study of Sequential Vaccinations With Fowlpox-CEA(6D)-Tricom (B7.1/ICAM/LFA3) and Vaccinia-CEA (6D)-Tricom, in Combination With GM-CSF and Interferon-Alfa-2B in

Brief Summary: This phase I trial is studying the side effects and best dose of interferon alfa-2b when given together with vaccine therapy and GM-CSF in treating patients with locally advanced or metastatic cancer that makes CEA. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill cancer cells that make carcinoembryonic antigen (CEA). Biological therapies, such as GM-CSF, may stimulate the immune system in different ways and stop cancer cells from growing. Interferon alfa-2b may interfere with the growth of cancer cells and slow cancer growth. Giving vaccine therapy together with GM-CSF and interferon alfa-2b may kill more cancer cells that make CEA.

Detailed Summary:

PRIMARY OBJECTIVES:

I. Determine the maximum tolerated dose and recommended phase II dose of interferon alfa-2b (IFN-α-2b) when administered with recombinant vaccinia-CEA(6D)-TRICOM vaccine, recombinant fowlpox-CEA(6D)-TRICOM vaccine, and sargramostim (GM-CSF) in patients with locally advanced or metastatic carcinoembryonic antigen (CEA)-expressing carcinoma.

SECONDARY OBJECTIVES:

I. Determine the effect of IFN-α-2b on tumor cell expression of CEA and MHC class I antigens in patients treated with this regimen.

II. Determine the immunologic effects of this regimen in these patients. III. Determine any objective anti-tumor responses that may occur in response to this regimen in these patients.

IV. Determine the time to tumor progression in patients treated with this regimen.

OUTLINE: This is a dose-escalation study of interferon alfa-2b (IFN-α-2b).

COURSE I: Patients receive recombinant vaccinia-CEA(6D)-TRICOM vaccine subcutaneously (SC) on day 1. Patients also receive sargramostim (GM-CSF) SC on days 1-4 and IFN-α-2b* SC on days 9, 11, and 13.

COURSES II-IV: Patients receive recombinant fowlpox-CEA(6D)-TRICOM vaccine SC on day 1. Patients also receive GM-CSF as in course 1 and IFN-α-2b* SC on days 1, 3, and 5.

NOTE: *The initial cohort of 6 patients does not receive IFN-α-2b.

Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. After 4 courses, p

Current Primary Outcome: MTD of IFN-alpha-2b, defined as the dose level one level beneath that dose at which 2 or more of 6 patients showed DLT, graded according to NCI CTCAE version 4.0 [ Time Frame: Up to 112 days ]

Original Primary Outcome:

Current Secondary Outcome:

  • Incidence of adverse events, graded according to NCI CTCAE version 4.0 [ Time Frame: Up to 15 years ]
    All patients will be evaluable for toxicity from the time of their first treatment with rF-CEA(6D)TRICOM and rV-CEA(6D)TRICOM.
  • Response to treatment, evaluated using the new international criteria proposed by the RECIST Committee [ Time Frame: Up to 15 years ]
    Each patient will be assigned one of the following categories: 1) complete response, 2) partial response, 3) stable disease, 4) progressive disease, 5) early death from malignant disease, 6) early death from toxicity, 7) early death because of other cause, or 9) unknown (not assessable, insufficient data). Patients in response categories 4-9 should be considered as failing to respond to treatment (disease progression).
