Vaccine Therapy in Treating Women With Metastatic Breast Cancer

Phase 1
Completed
Conditions
Breast Cancer
Registration Number
NCT00003184
Lead Sponsor
Providence Cancer Center, Earle A. Chiles Research Institute
Brief Summary

RATIONALE: Vaccines made from breast cancer cells may make the body build an immune response to kill tumor cells.

PURPOSE: Phase I trial to study the effectiveness of vaccines made from breast cancer cells in treating women with metastatic breast cancer.

Detailed Description

OBJECTIVES:

* Determine the safety and toxicity of vaccination strategies employing a CD80-transfected allogeneic breast cancer cell line (MDA-MB-231).

* Assess the immunologic response of lymphocytes isolated from lymph nodes draining the vaccination site following a single dose of CD80-transfected MDA-MB-231.

* Assess the development of systemic immunity following multiple injections of CD80-transfected MDA-MB-231.

* Observe for tumor regression.

OUTLINE: This is a dose-escalation study.

Patients receive intradermal vaccinations containing CD80-transfected cells with or without sargramostim (GM-CSF) or with or without BCG. Vaccinations are administered every 2 weeks for 6 weeks and then monthly for 3 months. Patients may receive 1 of 2 different doses of GM-CSF. GM-CSF is administered with the vaccination, then every 12 hours for 7 days. Monthly vaccinations may continue as long as response is shown.

Cohorts of 5 patients each are treated at each dose/combination. Each cohort completes treatment before the next cohort is accrued.

Patients are followed at weeks 4 and 8, then every 2 months for 6 months, then every 3 months for 1 year, and then every 6 months until disease progression.

PROJECTED ACCRUAL: Approximately 35 patients will be accrued for this study within 18 months.
