RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as vinorelbine, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining vaccine therapy with monoclonal antibody therapy and chemotherapy 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 women with locally recurrent or metastatic breast cancer. OBJECTIVES: Primary * Determine the efficacy of multiepitope autologous dendritic cell vaccine, trastuzumab (Herceptin\^®), and vinorelbine by measuring the change in the largest dimension of metastatic lesions, in women with locally recurrent or metastatic breast cancer that does not overexpress human epidermal growth factor receptor 2 (HER2)/neu. Secondary * Determine the ability of this regimen to induce functional antigen-specific T cells in these patients by measuring ex-vivo antigen-specific T-cell activity against peptide-pulsed dendritic cells and tumor targets by tetramer staining and intracellular cytokine assays. OUTLINE: * Autologous dendritic cell mobilization and harvest: All patients undergo autologous dendritic cell mobilization with filgrastim (G-CSF) and/or sargramostim (GM-CSF) subcutaneously daily for 4 days followed by apheresis. Mobilized peripheral blood is processed for the production of dendritic cells by cluster of differentiation (CD)34-positive cell selection. The dendritic cells are expanded and then pulsed with E75 and E90 peptides. * Treatment: Patients receive vinorelbine IV over 6-10 minutes and trastuzumab (Herceptin \^®) IV over 90 minutes on day 1. Patients also receive autologous dendritic cells pulsed with E75 and E90 peptides subcutaneously over 2-5 minutes on day 1\*. Treatment repeats every 14 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Note: \*If treatment is given locally, the vaccine therapy will be given at University of North Carolina (UNC) -Chapel Hill the following day. Patients are followed every 3 months. PROJECTED ACCRUAL: A total of 17-37 patients will be accrued for this study.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
56 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, all participants receive the same treatment. Since there is only one group, there is no need for randomization or assignment to different arms. This type of study is often used to test a new treatment without comparing it to another.

Other Ways to Assign Participants
Randomized allocation: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment: Participants are split into separate groups, each receiving a different treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Dendritic Cells: Dosage: 20 x 106 dendritic cells (DCs) given per treatment Vinorelbine:25 mg/m2 will be administered i.v biweekly Trastuzumab: 6mg/Kg administered by i.v. biweekly
Study Objectives
Primary Objectives

Response measured by Response Evaluation Criteria In Solid Tumors (RECIST), (Complete Response + Partial Response) Complete Response (CR)- Disappearance of all target lesions Partial Response (PR)-at least a 30% decrease in the longest diameters of target lesions, taking as reference the baseline longest diameter.
Secondary Objectives

Measured by intracellular cytokine staining for Interferon-gamma (INFgamma) and cluster of differentiation (CD107) up regulation and tetramer. A fourfold increase in the number of cluster of differentiation (CD8+) tetramers comparing prevaccine with peak postvaccine values indicated an immune response to the therapy.
