New Mouse T Cell Receptors as Potential Therapeutic Agents for the Treatment of Metastatic Cancer

Description of Technology: Adoptive immunotherapy is one of the most promising new therapeutic approaches to treat cancer.

T cell receptors (TCR) are the proteins responsible for the T cell's ability to recognize infected or transformed cells. A TCR consists of two domains, one variable domain that recognizes the antigen and one constant region that helps the TCR anchor to the membrane and transmit the recognition signal by interacting with other proteins.

This invention describes the identification of two mouse TCRs that target a common and highly expressed melanoma antigen, gp100, expressed by human cancers. These TCRs, have superior (100-1000 times) biological function compared to other human tumor-specific TCR that are currently in use in experimental trials using genetically engineered T cells. Therefore, these new TCRs represent potential therapeutic agents that can be used in the treatment of metastatic cancers, especially melanomas.

Applications: New mouse TCRs have been identified that recognize human gp100; The mouse TCRs have 100-1000 times superior biological function compared to their human counterpart in recognizing gp100 when expressed in human lymphocytes; Human T cells genetically engineered to express new TCRs can serve as potential therapeutic agents in the treatment of patients with metastatic cancers; Clinical trials with these novel TCRs are currently being planned.

Development Status: Pre-clinical work has been completed and clinical studies are forthcoming.

A Novel DNA Vaccine for the Treatment of Malignancies Expressing Immature Laminin Receptor Protein

Description of Technology: This invention describes a new potent chemoattractant-based DNA vaccine to evoke therapeutic anti-tumor responses against tumors. The vaccine targets the antigen presenting cells (APCs) to efficiently present an antigen to MHC class I and class II molecules to induce tumor specific CD4 and CD8 T cell responses.

The antigen tested is a highly conserved oncofetal antigen named immature laminin receptor protein (OFA-iLRP) that is preferentially expressed in malignant tissues. The vaccine construct consists of novel fusion proteins with enhanced binding affinities to augment antigen processing and antitumor responses.

Applications and Modality:

1. In vivo laboratory data shows that OFA-iLRP can be used as a potential immunotherapeutic antigen for the treatment of several malignancies including lymphoma, breast, lung, and ovarian.

2. The vaccine construct is a novel fusion protein designed to enhance immunogenicity of OFA-iLRP via delivering it to chemokine receptors expressed on antigen presenting cells.

3. The vaccine formulation will be most effective if used for treatment of cancer patients with minimal residual disease to protect from the disease relapse.

4. The vaccine potentially could be effective as a preventive measure for people with cancer predisposition by eliciting long term anti-OFA-iLRP humoral and cellular memory.

5. Very simple and less invasive vaccine that can be easily delivered to the skin, muscle or other tissues. Start Printed Page 19005

Market: Previous attempts to produce a vaccine construct with OFA-iLRP antigen have been laborious, expensive and non-reproducible showing no definitive demonstrations on the efficacy use of OFA-iLRP as a cancer vaccine. This simple chemoattractant based DNA vaccine is effective, potential cancer therapy with extensive in vivo data. It can be a valuable addition to the fast growing cancer vaccine market.

Development Status: The technology is currently in the pre-clinical stage of development and planned for clinical tests in patients with NSCLC (tentative start date 2008).

Transgenic Mouse Model that has Defective Innate and Adaptive Immunity

Description of Technology: The present research tool is a transgenic mouse model (C57BL/6 H-2b) that has defective innate and adaptive immunity. The mouse model harbors adaptive immunity cells, but lacks normal cellular responses and has an altered pattern of antibody production. The cells of the innate immune system (NK and NKT cells) are also nearly absent.

The mouse model lacks lymph nodes. The mouse model also lacks the ability to reject autologous, allogeneic, and presumably xenogeneic cells. The mouse model also has a defective antibody production mechanism, making only early antibodies (IgM) and little, if any, mature isotypes (G2a, G2b).

Applications and Modality:

1. New mouse model to study human tumors.

2. New mouse model to study immune function reconstitution.

3. New mouse model to study the development of lymph nodes and role of lymph nodes in the disease process.

4. Most mouse or human progenitor cells can be transferred to and engraft in the mouse model.

Market:

1. In 2006, 600,000 estimated deaths from cancer related diseases.

2. Immunotherapy market is expected to double in the next 5 years.

3. Research tool useful for adoptive immunotherapy studies.

Development Status: The technology is a research tool.
