A Phase I Vaccine Safety and Chemotherapy Dose-Finding Trial of an Allogeneic GM-CSF-Secreting Breast Cancer Vaccine Given in a Specifically Timed Sequence With Immunomodulatory Doses of Cyclophosphamide and Doxorubicin
OBJECTIVES:
Primary
- Determine the safety of vaccination comprising allogeneic sargramostim
(GM-CSF)-secreting breast cancer cells with or without immunomodulation using
cyclophosphamide and doxorubicin in women with stage IV breast cancer.
- Determine the doses of cyclophosphamide and doxorubicin that maximize vaccine-induced
immunity, in terms of immune response to HER2/neu, in patients treated with these
regimens.
- Compare in vivo immune response induced by these regimens, as measured by
immunohistochemical analysis of vaccine site biopsies from these patients, with
responses seen in prior preclinical and clinical studies.
Secondary
- Determine the time to disease progression in patients treated with these regimens.
OUTLINE: This is a dose-finding study.
The first 6 patients receive 1 of 2 doses of vaccine comprising allogeneic sargramostim
(GM-CSF)-secreting breast cancer cells intradermally (ID) on day 0. Subsequent patients
receive cyclophosphamide IV on day -1, vaccine at the higher dose ID on day 0, and
doxorubicin IV on day 7. Treatment in all patients repeats every 4-6 weeks for 3 courses in
the absence of disease progression or unacceptable toxicity. Patients with stable or
responding disease after the third course receive a fourth course of treatment at
approximately 4 months after completion of the third course.
Cohorts of 2-3 patients receive a fixed dose of vaccine in combination with escalating doses
of doxorubicin and cyclophosphamide. Doses of cyclophosphamide and doxorubicin are escalated
until an optimal dose of combination chemotherapy with a fixed dose of vaccine is achieved.
Patients are followed at 1 month and 4 months after completion of study therapy and then
annually thereafter.
PROJECTED ACCRUAL: A total of 6-60 patients will be accrued for this study.
