Official Title: Phase I Study of a Recombinant Fowl Pox Vaccine rF-CEA (6D)/TRICOM Alone or With GM-CSF in Patients With Advanced CEA Expressing Adenocarinomas

Brief Summary: Phase I trial to study the effectiveness of vaccine therapy with or without sargramostim in treating patients who have advanced or metastatic cancer. Vaccines may make the body build an immune response to kill tumor cells. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood. Combining vaccine therapy with sargramostim may make tumor cells more sensitive to the vaccine and may kill more tumor cells

Detailed Summary:

PRIMARY OBJECTIVES:

I. Determine the toxicity of recombinant fowlpox-CEA-TRICOM vaccine with or without sargramostim (GM-CSF) or recombinant fowlpox-GM-CSF in patients with advanced or metastatic CEA-expressing adenocarcinomas.

II. Determine the CEA-specific T-cell precursor frequency in patients treated with these regimens.

III. Assess the immunogenicity of GM-CSF in patients treated with these regimens.

IV. Determine the inflammatory response and cytokine expression at the vaccination site in these patients 48 hours after vaccination.

V. Correlate telomere length of leukocytes with prior cytotoxic therapies and immunologic response in patients treated with these regimens.

OUTLINE: This is a dose-escalation study. The first three cohorts of 3-12 patients receive escalating doses of recombinant fowlpox-CEA-TRICOM vaccine (fCEA-TRI) until the maximum tolerated dose (MTD) is determined.

The MTD is defined as the dose preceding that at which 2 of 6 patients or 3 of 12 patients experience dose-limiting toxicity. fCEA-TRI is administered intradermally every 2 weeks for 4 doses and then every 2 months thereafter (beginning on day 56) in the absence of disease progression or unacceptable toxicity.

The fourth and fifth cohorts of 6 patients receive fCEA-TRI at the MTD in the same manner as the first three cohorts combined with escalating doses of sargramostim (GM-CSF). GM-CSF is administered subcutaneously once daily beginning on the day of each vaccination and continuing for a total of 4 days.
