Brief Summary: Vaccines may make the body build an immune response to kill tumor cells This phase I trial is studying the side effects and best dose of vaccine therapy in treating patients with metastatic breast cancer
Detailed Description: PRIMARY OBJECTIVES
I To assess the toxicity associated with repeated vaccination with an admixture of recombinant vaccinia viruses rV-MUC-1 and rV-TRICOM
II To determine the maximum tolerated dose MTD of rV-MUC-1 and rV-TRICOM vaccine admixture
III To evaluate the toxicity of adding GM-CSF to the admixture of the rV-MUC-1 and rV-TRICOM
SECONDARY OBJECTIVES
I To assess host immune reactivity following rV-MUC-1 and rV-TRICOM with and without GM-CSF administration
II To determine whether vaccination with rV-MUC-1 and rV-TRICOM with and without GM-CSF is associated with antitumor activity
OUTLINE This is an open-label dose-escalation study
Patients receive vaccination comprising recombinant vaccinia-MUC-1 and recombinant vaccinia-TRICOM vaccine intradermally on days 1 and 29 for a total of 2 doses in the absence of disease progression or unacceptable toxicity
Cohorts of 3-6 patients receive escalating doses of recombinant vaccinia-MUC-1 and recombinant vaccinia-TRICOM vaccine until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity Once the MTD is determined an additional 10 patients including 5 HLA-A2-positive patients receive vaccination as above at the MTD and sargramostim GM-CSF subcutaneously on days 1-4 and 29-32
Patients are followed at 4 weeks monthly until disease progression and then annually for up to 15 years
PROJECTED ACCRUAL A total of 11-22 patients will be accrued for this study within 18-24 months
