A Phase I Vaccine Trial of a HER-2/Neu Peptide Incorporated Into PLG Microspheres in Patients With Advanced Stage HER2-Expressing Cancers
RATIONALE: Vaccines may make the body build an immune response to tumor cells.
Colony-stimulating factors such as sargramostim increase the number of immune cells found in
bone marrow or peripheral blood.
PURPOSE: Phase I trial to study the effectiveness of vaccine therapy plus sargramostim in
treating patients who have stage III or stage IV cancer.

PURPOSE: Phase I trial to study the effectiveness of vaccine therapy plus sargramostim in
treating patients who have stage III or stage IV cancer.
OBJECTIVES: I. Determine the safety of serial intradermal or subcutaneous vaccinations of
HER-2 derived p369-377 peptide incorporated into polylactide-co-glycolide (PLG) microspheres
with adjuvant sargramostim (GM-CSF) in patients with stage III or IV HER-2 expressing
cancers. II. Determine whether cytotoxic T lymphocytes (CTL) specific for the HER-2 protein
can be elicited in patients with HLA-A2 by immunization with this regimen. III. Determine
which route of immunization, intradermal or subcutaneous, is more effective in generating
HER-2 specific CTL in these patients on this regimen. IV. Determine the extent to which
escalated dose of PLG peptide affects the immune response in these patients on this regimen.
OUTLINE: Patients undergo leukapheresis prior to study and after final vaccination. Patients
are sequentially entered into one of three treatment arms: Arm I: Patients receive an
intradermal vaccination of HER-2 derived p369-377 peptide incorporated into
polylactide-co-glycolide (PLG) microspheres with adjuvant sargramostim (GM-CSF). Arm II:
Patients receive a subcutaneous vaccination of HER-2 derived p369-377 peptide incorporated
into PLG microspheres with adjuvant GM-CSF. Arm III: Patients receive a higher dose of
subcutaneous vaccination of HER-2 derived p369-377 peptide incorporated into PLG microspheres
with adjuvant GM-CSF. Treatment repeats every 4 weeks for up to 6 courses in the absence of
unacceptable toxicity.
PROJECTED ACCRUAL: A total of 15 patients (5 per treatment arm) will be accrued for this
study.
