HER2-positive Breast Cancer, Male Breast Cancer, Stage IV Breast Cancer
Conditions
Brief summary
RATIONALE : Laboratory-treated T cells may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vaccines made from HER2 peptides may help the body build an effective immune response to kill tumor cells that express HER2. Giving laboratory-treated T cells and cyclophosphamide after vaccine therapy may be an effective treatment for breast cancer. PURPOSE: This phase I trial is studying the side effects and best dose of ex vivo-expanded HER2-specific T cells when given together with cyclophosphamide after vaccine therapy in treating patients with HER2-positive stage IV breast cancer.
Detailed description
PRIMARY OBJECTIVES: I. To evaluate the feasibility of expanding HER-2-specific effector T cells (TE) ex vivo from CD62L+ TCM and CD62L- TEM from patients immunized with a HER-2 peptide vaccine. II. To evaluate the safety of infusing autologous ex vivo expanded HER-2-specific T cells into patients with advanced HER-2+ breast cancer. SECONDARY OBJECTIVES: I. To evaluate the persistence, function, and phenotype of adoptively transferred HER-2-specific TE cells derived from TCM or TEM precursors. II. To investigate the potential anti-tumor effects of therapy with ex vivo expanded HER-2-specific T cells in patients with advanced HER-2+ breast cancer. OUTLINE : This is a dose-escalation study of ex vivo-expanded HER2-specific T cells. VACCINE THERAPY: Patients receive HER2 peptide vaccine intradermally once weekly for 3 weeks. CHEMOTHERAPY: Patients receive cyclophosphamide IV on day -1. IMMUNOTHERAPY: Patients receive ex vivo-expanded HER2 specific T-cell IV over 30 minutes on days 1, 10, and 20. After completion of study treatment, patients are followed up on days 28, 35, 49, 63 and then monthly thereafter for 1 year.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ability to expand HER-2-specific T cells ex vivo from memory T cell subsets which are derived from patients with advanced HER-2 expressing cancer | After leukapheresis (2 weeks after 3rd vaccination) and prior to chemotherapy | Ability to expand HER-2-specific T cells ex vivo from memory T cell subsets which are derived from patients with advanced HER-2 expressing cancer will be defined as feasible if the minimum target expansion of HER-2-specific T cells is achieved in ≥2/3 expansions in ≥7/10 subjects. |
| Safety and systemic toxicity as assessed at regular time points by NCI common toxicity criteria (CTCAE v 4.0). Stopping rules for the study protect patients against therapy with a rate of severe toxicity of 20% or greater. | At week 1, 2, 3, post T-Cell infusion day 1, 10, 20, 28, 35, 49, 63, then every 3 months for a year. | — |
Secondary
| Measure | Time frame |
|---|---|
| Extent to which to HER-2-specific T cell immunity can be boosted successfully with adoptive immunotherapy will be defined by quantitative assessment of HER-2-specific CD8+ T cells assessed by cytokine flow cytometry (CFC), Elispot, and tetramer staining | Post T-Cell-infusion on day 10, 20, 28, 35, 49, 63, then monthly for one year. |
| Persistence of T cell immune augmentation in vivo after adoptive transfer of HER-2-specific T cells as assessed by presence of HER-2-specific central memory T cells and effector memory T cells | Every month for 1 year following the last infusion |
