The type 1 insulin-like growth factor (IGF) receptor (IGF1R) is over-expressed by many tumors and mediates proliferation, motility, and protection from apoptosis. Agents that inhibit IGF1R expression or function can potentially block tumor growth and metastasis.
The present invention relates to the identification of soluble fragments of the IGF1R ectodomain, where these fragments bind IGF-I, IGF-II, or the various other ligands of IFG1R. The identified fragment may be useful for identifying agents that block IGF1R and may act as a strong dominant negative inhibitor of tumor growth by blocking the IGF1R pathway. The invention also encompasses other IGF1R fragments or derivatives of the original fragments, methods of identifying IGF1R fragments or other similar fragments in the IGF1R ectodomain, methods of using said fragments to block binding of ligands, and methods of producing antibodies against the IGF1R fragments.
The technology is available for licensing under a biological material license. In addition to licensing, the technology is available for further development through collaborative research opportunities with the inventors.

Molecules based on monoclonal antibodies hold the promise of highly selective therapeutics. However, their efficacy can be limited by poor tissue penetration, rapid renal clearance and an immune response to the antibody. The present technology provides an immunotoxin that is modified to overcome such limitations.
The technology relates to polymer-conjugated immunotoxins targeted to the mesothelin tumor cell antigen. These polymer-immunotoxin conjugates possess an enhanced therapeutic index and may provide improved methods of treating tumors and cancers expressing the mesothelin antigen.

This invention relates to the identification of a tumor suppressor gene named Caliban from Drosophila melanogaster. The inventors have demonstrated that Caliban is very similar to the corresponding human gene and they have shown that the human gene is inactive in human lung cancer cells but active in normal lung cells. For the first time, it has been shown that when full length Caliban is expressed in human lung cancer cells they lose many of their tumorigenic properties. Hence, using gene therapy to replace the inactive gene with full length Caliban may treat cancer. Details of this were published in Bi et al., “Drosophila caliban, a nuclear export mediator, can function as a tumor suppressor in human lung cancer cells,” Oncogene advance online publication, August 15, 2005; doi:10.1038/sj.onc.1208962.
This invention also provides a biomarker assay that can be used to determine if the fly or human tumor suppressor Caliban gene product is functioning in cells. This assay uses a peptide from the fly gene Prospero, named HDA, which when fused to a reporter such as green fluorescent protein, is exported from the nucleus when Caliban is working.

The technology relates to methods and compositions of matter used to identify and treat metastatic cancer. Using genetics, the inventors identified the mouse Sipa-1 gene as a possible metastasis modifying gene. Further analyses revealed that Sipa-1 expression levels correlate with metastasis. The inventors developed compounds that modulate Sipa-1 expression and reduce metastasis in animal models. The inventors also identified single nucleotide polymorphisms (SNPs) present in the mouse Sipa-1 gene that, if also present in humans, could serve as the basis for diagnosing cancer and metastasis.

The present invention relates to methods for the diagnosis and staging of thyroid cancer. The invention employs analysis of gene expression using microarrays or quantitative RT-PCR to distinguish between malignant and benign tumors. Primer and probe sequences are described that represent a six gene or ten gene model for diagnosing benign and malignant thyroid cancer. Analysis of the expression of these genes in thyroid lesions taken from patients could be used for molecular classification of the lesions. As analysis of thyroid lesions by traditional means, such as fine needle biopsy with cytologic examination, can result in indeterminate results, the current invention may provide a superior method for molecular diagnoses of thyroid cancer.
This research is described, in part, in Mazzanti et al., “Using gene expression profiling to differentiate benign versus malignant thyroid tumors,” Cancer Res. 2004 Apr 15 64(8):2898-2903.

Vaccinia-based vaccines have a proven record of being effective vaccines in humans as well as in animals. However, accumulating evidence reveals the need for technology to improve the immune responses such vaccines generate.
The present invention discloses recombinant vaccinia viruses capable of expressing interleukin 15 (IL-15), and methods for modulating immune responses using such viruses. This invention shows that by inserting the human IL-15 gene into the vaccinia genome, more effective vaccines can be generated against infectious agents and cancer. Currently, IL-2 has been approved by the FDA for use in the treatment of patients with metastatic renal cell carcinoma or with metastatic melanoma. It has been used as a component of cancer vaccines and in various approaches for the treatment of AIDS. However, administration of IL-2 is associated with activation-induced cell death (AICD), and may lead to death of T-cells that recognize the antigens expressed in the tumor cells. Thus, IL-15 may be a superior agent in the treatment of cancer, or as a component of a vaccine directed towards cancer or infectious agents. Co-expression of IL-15 with antigens during the immunization process, according to the current invention, leads to induction of CD8+ memory T cells with higher avidity that proliferate more effectively in vivo and persist much longer in the immunized individual in addition to enhancing the levels and persistence of antigen specific antibodies thus providing substantially longer lasting cellular and humoral immunity.
This invention has the potential to be used in a variety of ways, including: (i) an improved, more efficacious vaccine candidate for smallpox, (ii) for incorporation into existing vaccinia based vaccines to enhance and confer superior long lasting immune response to viral and cancer antigens, or (iii) as a valuable source material for IL-15 production, especially should IL-15 be proven as an alternate of more efficacious cytokine than IL-2.
This research has been described, in part, in SK Oh et al., “Coadministration of HIV vaccine vectors with vaccinia viruses expressing IL-15 but not IL-2 induces long-lasting cellular immunity,” Proc. Natl. Acad. Sci USA 2003 Mar 18;100(6):3392-3397, online publication 10.1073/pnas.0630592100.

The invention relates to compositions of matter and methods for treating arthritis by modulating Tumor Necrosis Factor Alpha (TNFalpha) signaling. TNFalpha plays a key role in the pathogenesis of numerous diseases including rheumatoid and septic arthritis, and other autoimmune and inflammatory diseases. TNFalpha mediates its effects through receptors that contain a Pre-ligand Assembly Domain (PLAD). The inventors have discovered compounds that interfere with PLAD can block the effects of TNFalpha in vitro. Treatment of mice with these compounds in vivo ameliorated disease in several models of arthritis. Therefore, the compositions and methods of the current invention may lead to novel arthritis treatments.

Chronic myelogenous leukemia (CML) is almost universally associated with a translocation that juxtaposes the Bcr and Abl genes. Because the resulting kinase, p210 Brc/Abl, is found exclusively in malignant hematopoietic cells there has been considerable interest in identifying inhibitors of this enzyme. Adaphostin induces cytotoxicity in human leukemia cells by down-regulating p210 Bcr/Abl, inducing DNA damage and initiating apoptosis. Adaphostin exhibits selectivity for CML myeloid progenitors in vitro and retained its catholicity when cytotoxicity mesylate-resistant K562 cells were examined. Adaphostin may kill a wide range of human leukemia cells and may be effective against other cancer types. The present invention provides pharmaceutical compositions comprising effective amounts of adaphostin. The compound and composition of the present invention may be used for treating human leukemia and other proliferative diseases.

The identification of tumor-associated antigens and the cloning of DNA sequences encoding them have enabled the development of anticancer vaccines. Such vaccines target tumors by stimulating an immune response against the antigens. One method of vaccination involves the delivery of antigen-encoding DNA sequences, and a number of recombinant vectors have been used for this purpose. To optimize the efficacy of recombinant vaccines, Dr. Steve Rosenberg and colleagues at the NCI have developed treatment regimens that use two different vectors (i.e., heterologous boosting).
The present invention describes the method of heterologous boosting immunizations, which in essence is the use of a priming vaccination and a boosting vaccination using two different recombinant vectors that contain a similar or different tumor associated antigen (TAA). The use of different recombinant vectors unexpectedly increases and maintains the immune response to most tumor-associated antigens included in the vectors. The claims are directed, but not limited to, various recombinant viral vectors: poxvirus, vaccine, adenovirus, etc. Additional embodiments and claims are directed, but not limited to, melanoma tumor antigens such as Mart1, gp100, or Hep B surface antigen. These tumor antigen expressing recombinant vectors are coupled with distinctly different recombinant vectors, which express various cytokines and co-stimulatory and accessory molecules such as B7-1, B7-2, ICAM-1, etc. This therapeutic intervention could be directed toward multiple human carcinomas but, with respect to this technology, has been customized as a therapeutic intervention for melanoma.
