Major projects include: (1) development of tumor antigen specific vaccines for the prevention of solid tumor relapse, (2) generation and characterization of cytotoxic CD8+ and CD4+ helper T cells specific for tumor antigens for eventual use in adoptive immunotherapy to treat advanced stage disease, (3) evaluation of antibody responses to various cancer causing proteins for use as a potential cancer diagnostic, (4) development of biologically relevant animal models for solid tumors to assess the effect of the generation of an immune response to immunogenic cancer proteins and to evaluate different vaccine and adoptive immunotherapy strategies, (5) phase I/II clinical trials of peptide and DNA vaccines targeting specific cancer antigens, (6) phase I/II clinical trials of infusion of antigen competent T cells in patients with advanced stage solid tumors, (7) antigen discovery in solid tumors using molecular immunology and protein based techniques, and (8) development of in vivo imaging techniques for tracking tumor specific T cells and assessing the response to tumor specific immunotherapy.
Studies from our laboratory have demonstrated that some patients with breast cancer have existent immunity to the HER-2/neu (H2N) protein which is the product of the amplified HER-2/neu oncogene. Therefore, the H2N protein is a tumor antigen. Developing immunotherapy targeting the H2N oncogenic protein via therapeutic vaccination and infusion of H2N specific T cells is a major goal of our work. We have identified breast cancer patients with both specific antibody and specific T cell responses to the protein. In addition, we have been able to generate cytotoxic T cells (CD8+) with an ability to specifically kill breast cancer cells via recognition of H2N protein. The detection of immunity to an oncogenic protein intimately involved in the growth and malignant potential of breast cancer has several profound ramifications. Methods to augment the existent immunity such as T cell therapy or vaccination might have a therapeutic effect. Our laboratory is currently evaluating the potential use ofH2N immunity inthe treatment of breast cancer, and is identifying potential target epitopes for T cell and vaccine therapy.
In addition to human studies, we have developed an animal model to study the effect of generating immunity to the H2N protein. One important feature of the H2N oncoprotein is that it is a non-mutated , overexpressed normal protein. The rat is an ideal model. Rat neu is 89% homologous to human H2N and the distribution of normal neu is similar, being found at low levels inskin and digestive tract epithelium. The major issues we are addressing in the rat model are how best to circumvent tolerance to H2N and whether levels of immunity necessary for tumor eradication cause any autoimmune toxicity. These studies should bedirectly applicable to humans as the structure, function, expression, and distribution of H2N is homologous in rats and humans. Results from these investigations will be directly applicable to the
treatment of breast cancer patients.
Extrapolatingfrom animal models of T cell therapy, treatment of human breast cancer should be possible provided that enough immune T cells can be generated and provided that the T cells are immune to the appropriate antigen. Theoretically, H2N is an appropriatetarget antigen. It is our hope that T cellvaccines an T cell therapy will be of benefit in cancer therapy, and, in addition, give the patient the ability to
protect against future relapse by the augmentation of her own immune defenses.
