Photosensitizing Antibody-Fluorophore Conjugate for Photo-Immunotherapy
Description of Invention: A major goal of targeted cancer therapy
is to improve the sensitivity and specificity of the therapy so that
cancer cells can be detected and targeted for elimination, while normal
cells in the surrounding area remain largely intact. Photodynamic
therapy (PDT) is a treatment for cancer and non-cancerous lesions
involving light and a photosensitizer. The photosensitizer can be
targeted to a specific cell using antibodies specific for proteins
expressed on the target cell surface, the target cells will then be
destroyed after being exposed to light at appropriate wavelength.
The NIH technology describes a method of photosensitizing cancerous
cells by irradiating an antibody fluorophore conjugate. The NIH
investigators have conducted in vitro studies using a proprietary IRDye
700DX NHS Ester. The IR700 dye was conjugated to a proprietary
humanized anti-HER1 or anti-HER2 or anti-PSMA antibody, Panitumumab or
Trastuzumab or huJ591. Subsequent irradiation of non-ionizing near
infrared light showed rapid cell death of tumor cells, while normal
cells were not noticeably killed. The studies were repeated in mice
with similar results.
Applications and Market:
Photodynamic therapy for cancer by selective targeting and
killing of cells without suffering normal tissue side effects.
Cancer was responsible for about 13% of all human deaths
in 2007. There remains a need for therapies that effectively kill the
tumor cells while not harming non-cancerous cells.
Development Status: Both in vitro and in vivo data available.

Soluble Glypican-3 Protein for Treatment of Cancer
Description of Technology: Hepatocellular carcinoma (HCC) is a form
of liver cancer that is among the more deadly cancers in the world. HCC
is typically only detected at the later stages of cancer development,
which is always associated with poor prognosis. Because HCC is often
associated with liver disease, traditional chemotherapy is not an
option, making surgery the most common form of treatment. As a result,
there is a need for new treatments.
Glypican-3 (GPC3) is a cell surface protein that is normally
involved in cell growth and differentiation. GPC3 has been shown to act
through the Wnt-signaling pathway, a pathway that is often activated in
a number of different cancer cell types. Significantly, the ability of
GPC3 to activate signaling through Wnt requires that GPC3 be bound to
the cell membrane. GPC3 is also preferentially expressed on HCC cells,
suggesting it could play a particularly important role in tumorigenesis
in HCC.
This invention concerns a soluble form of GPC3 that lacks its cell
membrane anchoring domain. This soluble form of GPC3 maintains its
ability to interact with the Wnt signaling pathway, but cannot induce
the activation of the pathway because it is not bound to the cell
membrane. By competing with fully functional GPC3, the soluble GPC3 is
able to inhibit the growth of HCC cells, thereby decreasing the ability
of tumors to grow and metastasize. This suggests that soluble GPC3
represents a possible therapeutic for HCC.
Applications:
Soluble GPC3 represents a potential therapeutic for
patients with cancer with hyperactivated Wnt-signaling pathways.
Specific cancers include hepatocellular cancer (HCC),
melanoma, thyroid cancer, lung squamous cell carcinoma, Wilms' tumor,
neuroblastoma, hepatoblastoma, and testicular germ-cell tumors.
Advantages:
Removal of the glycosyl-phosphatidylinositol (GPI) anchor
results in a soluble form of GPC3 that can interrupt Wnt-signaling.
Soluble GPC3 maintains the ability to compete with fully
functional GPC3 despite its inability to activate signaling.
For treatment of HCC, offers a non-invasive, potentially
non-liver toxic alternative to current strategies.
Development Status: Preclinical stage of development; cell culture
data with HCC cells

Drug Combination of DNA Topoisomerase I (TOP1) Inhibitors and
Extracellular ATP Produces a Significant Increase in Beneficial Anti-
Carcinoma Cytotoxicity
Description of Invention: DNA Topoisomerase inhibitors are a
category of drugs used for cancer therapy. DNA topoisomerase 1 (TOP1)
inhibitors, such as Camptothecin (CPT) and its structurally related
analogues, bind to the TOP1 complex and prevent the religation of the
single strand DNA molecules, ultimately leading to cell death. CPT and
close analogues show anticancer activity in clinical trials treating
ovarian, small-cell lung, and colorectal cancers, but also adverse drug
reaction. By reducing the cytotoxic dose in the thousands of folds, the
NIH scientists are able to target the tumor and reduce the cytotoxicity
to normal cells. The instant invention discloses that the drug
combination of DNA topoisomerase 1 (TOP1) inhibitors, such as the anti-
cancer drug Camptothecin (CPT), and extracellular ATP produces a
significant increase in beneficial anti-carcinoma cytotoxicity.
Applications and Market:
This invention may provide a new combination of drug with
extracellular ATP to target various cancers for treatment.
Cancer is the second leading cause of death in the U.S.
The National Cancer Institute estimate the overall annual costs for
cancer in the U.S. at $107 billion; development of more effective
therapies with less adverse drug reaction is always in high demand.
Development Status: Pre-clinical stage of development.

Novel Prognostic and Therapeutic Biomarker for Cancer and Inflammatory
Diseases
Description of Invention: There remains a significant unmet need
for diagnostics, prognostics, and therapeutics for conditions that
involve inflammation and the formation of blood clots such as bleeding
disorders, trauma, and diseases such as sepsis, cardiovascular disease,
stroke, and cancer. The global market for such products is varied and
competitive, and is forecast to be over $40 billion by 2010.
Researchers at the National Cancer Institute (NCI) have identified
that levels of a novel soluble protein involved in the repair mechanism
for damaged blood vessels correlate with outcome in sepsis and with the
diagnosis of disseminated intravascular coagulation, a contributing
factor to the morbidity and mortality associated with sepsis.
Further, the NCI researchers have demonstrated that a recombinant
version of this novel protein facilitates the clotting of blood,
suggesting a potentially significant therapeutic benefit for the
treatment of bleeding disorders or trauma.
Applications:
Diagnostic and prognostic biomarker for diseases that
involve inflammation and blood clot formation (i.e., sepsis,
cardiovascular disease, stroke, cancer).
Treatment of bleeding disorders or trauma.
Treatment of cerebral bleeding associated with aneurism or
stroke.
Therapy for patients with low platelet counts.
Therapy for women suffering from preeclampsia or
thrombotic episodes.
Advantages:
High specificity.
Protein levels correlate with disease state/outcome.
Administration of recombinant protein accelerates the
formation of blood clots.
Development Status: Pre-clinical.

Treatment and Prevention of Inflammatory Bowel Disease (IBD) Using
Mutant and Chimeric IL-13 Molecules
Description of Invention: Ulcerative colitis (UC) is a chronic
inflammatory disease of the colorectum and affects approximately
400,000 people in the United States. The cause of UC is not known,
although an abnormal immunological response to bacterial antigens in
the gut microflora is thought to be involved. Present treatments for UC
include anti-inflammatory therapy using aminosalicylates or
corticosteroids, as well as immunomodulators and diet. However, 25-40%
of ulcerative colitis patients must eventually have their colons
removed due to massive bleeding, severe illness, rupture of the colon,
risk of cancer or due to side effects of corticosteroids and novel
treatments are still actively being sought. NIH scientists and their
collaborators have used a mouse model of experimental colitis
(oxazolone colitis, OC) to show that IL-13, a Th2 cytokine, is a
significant pathologic factor in OC and that neutralizing IL-13 in
these animals effectively prevents colitis.
OC is a colitis induced by intrarectal administration of a
relatively low dose of the haptenating agent oxazolone subsequent to
skin sensitization with oxazolone. A highly reproducible and chronic
colonic inflammation is obtained that is histologically similar to
human ulcerative colitis. Studies show that Natural Killer T (NKT)
cells, rather than conventional CD4+T cells, mediate oxazolone colitis
and are the source of IL-13 as well as being activated by CD1-
expressing intestinal epithelial cells. Tissue removed from ulcerative
colitis patients were also shown to contain increased numbers of
nonclassical NKT cells that produce markedly increased amounts of IL-13
and that in keeping with epithelial damage being a key factor in UC,
these NKT cells are cytotoxic for epithelial cells. Building on their
previous work, scientists at NIAID and FDA have shown that an Il-13
chimeric fusion protein linked to an effector molecule was able to
prevent colitis in a mouse model of ulcerative colitis.
Available for licensing are methods for treating or preventing the
inflammatory response of IBD by inhibiting the binding of IL-13 to IL-
13 receptors on NKT cells. Additionally, these mutant and chimeric Il-
13 molecules are able to block the chronic
[[Page 66110]]
inflammatory response that results in fibrosis as seen in Crohn's
disease. Preventing the inflammatory response of colitis by either
modulating or blocking IL-13 and NKT cell activity continues to be an
effective therapeutic approach in animal models of colitis with
implications for the treatment of human ulcerative colitis and for the
treatment of fibrosis associated with Crohn's disease.
