Phase II Trial Evaluating the Toxicity and Efficacy of a Multiepitope Dendritic Cell Vaccine Given With Trastuzumab and Vinorelbine Ditartrate for the Treatment of Women With Metastatic Breast Cancer That Express HLA-A0201 and Whose Tumors Overexpress HER-2/NEU
In Brief
A Phase 2 clinical trial evaluating sargramostim, therapeutic autologous dendritic cells, and 2 other interventions for Breast Cancer. Completed, enrolled 17 participants across 1 site.
Detailed Summary
RATIONALE: Vaccines made from a person's white blood cells may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as vinorelbine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vaccine therapy together with trastuzumab and vinorelbine may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving vaccine therapy together with trastuzumab and vinorelbine works in treating patients with locally recurrent or metastatic breast cancer.
Study Details
Timeline
Interventions
All patients will receive Leukine (GM-CSF) at 250 mcg/m2 starting one day after the administration of chemotherapy x 7 days. Patients with neutrophil counts below 1,000/mm3 on day 8 will continue GM-CSF therapy until the neutrophil count is greater than 1,000/mm3.
patients will receive (10 x 106) peptide-pulsed DCs given by i.d injection into either axilla or the inguinal region with each peptide given into a separate site. The total dose will be 20 x 106 DCs given per treatment.
Trastuzumab will be infused in the side-port of a freely flowing IV over 90 minutes and at 6mg/kg if the subject has not previously received Trastuzumab, or if it has been more than 30 days since any prior trastuzumab administration. If the subject has previously received Trastuzumab within 30 days and has no adverse history with the drug, the infusion will be given over 30 minutes. If the subject is currently receiving Trastuzumab, the first study infusion will be given at 4mg/kg over 30 minutes. Subsequently, Trastuzumab will be infused at 4 mg/kg in the side-port of a freely flowing IV over 30 minutes.
Vinorelbine 25 mg/m2 will be administered IV over six to ten minutes into the side port of a freely flowing IV line.
