Vaccine Therapy in Treating Patients With Metastatic Breast Cancer

Stage IV Breast Cancer Clinical Trial

Official title: A Phase I Trial of An Admixture of Recombinant Vaccinia Virus That Express DF3/MUC1 and rV-TRICOM (B7.ICAM-1, and LFA-3) in Patients With Metastatic Adenocarcinoma of The Breast

Status Terminated

Clinical Trial 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.

Clinical Trial 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. ;
