Use of Antisense Oligodeoxynucleotides (ODNs) for Inhibiting JC Virus 
(JCV)

    Description of Technology: Progressive multifocal 
leukoencephalopathy (PML) is a rare, fatal demyelinating disease of the 
brain caused by the polyomavirus JC (JCV) under immunosuppressive 
conditions. It is pathologically characterized by progressive damage of 
white matter of the brain by destroying oligodendrocytes at multiple 
locations. Clinically, PML symptoms include weakness or paralysis, 
vision loss, impaired speech, and cognitive deterioration. The 
prognosis of PML is generally poor. No effective therapy for PML has 
been established. The current strategies to develop a PML therapy focus 
on blocking viral infection or inhibiting JCV replication. Antisense 
oligodeoxynucleotides (ODNs) that can block JCV replication and 
multiplication have been identified and optimized. Use of the ODNs 
provide a method of inhibiting JCV replication and thereby provide a 
treatment for PML.
    Potential Commercial Applications:
     JCV/PML Therapeutics.
     JCV Diagnostics.
     JCV Kits.
    Competitive Advantages:
     Low cost PML therapeutics.
     Lower cost JCV diagnostics.
     Ease of synthesis.

A Novel HIV-1 Anti-HIV and Anti-Retroviral Compound

    Description of Technology: The subject invention describes the 
thioether prodrug that targets the highly conserved nucleocapsid 
protein 7 (NCp7) of HIV. In contrast to clinically approved anti-
retroviral drugs used to treat HIV, the virus is not able to develop 
resistance to the drug in this invention. In addition, the prodrug is 
stable at room temperature, crystalline, easily synthesized in two 
steps on the kilogram scale from inexpensive starting materials, orally 
bioavailable, and is non-toxic in all animal models investigated to 
date. There is potential to use the molecule described in the invention 
as an orally administered systemic drug for the treatment of HIV 
infection either alone or in combination with other approved anti-
retroviral therapies.
    Animal safety testing is in process as are efficacy studies.
    Potential Commercial Applications:
     HIV therapeutics.
     Prophylactics.
     Topical application.
    Competitive Advantages:
     Does not develop resistance due to the high sequence 
conservation of the target.
     More stable than thioesters.
    Development Stage:
     Early-stage.
     Pre-clinical.
     In vitro data available.
     In vivo data available (animal).

Mouse Model for Methylmalonic Acidemia, an Inherited Metabolic Disorder

    Description of Technology: Methylmalonic Acidemia (MMA) is a 
metabolic disorder affecting 1 in 25,000 to 48,000 individuals 
globally. MMA is characterized by increased acidity in the blood and 
tissues due to toxic accumulation of protein and fat by-products 
resulting in seizures, strokes, and chronic kidney failure. About 60% 
of MMA cases stem from mutations in the methylmalonyl CoA mutase (MUT) 
gene encoding a key enzyme required to break down amino acids and 
lipids. Previous efforts to develop mice with null mutations in MUT 
have been unsuccessful, as such mutations result in neonatal death.
    The inventors have developed the first transgenic mouse model 
available for the long-term study of Mut deficiency, in which low level 
liver-specific expression of the MUT enzyme confers rescue from 
neonatal lethality and replicates induction of the severe renal 
symptoms consistent with human MMA. This model could serve as a 
valuable research tool for designing treatments for MMA renal disease 
or a platform for pre-clinical toxicology screening of compounds with 
potential renal side effects.
    Potential Commercial Applications:
     Model for examining renoprotective antioxidants or 
treatments for kidney failure resulting from drug toxicity, 
mitochondrial dysfunction, environmental exposure, or aging.
     Used in investigating renoprotective effects of 
nutritional supplements from drugs known to cause kidney damage.
     Used in discovery of MMA biomarkers.
    Competitive Advantages: The model system provides a relatively non-
invasive means of assessing the efficacy of renal-targeted therapies of 
all classes and biological types (gene therapy, small molecules, 
nutritional supplements, repurposed drugs).
    Development Stage:
     Early-stage.
     Pre-clinical.
     In vitro data available.
     In vivo data available (animal).

Reporter Plasmid To Identify Cancer Stem Cells

    Description of Technology: Scientists at the NIH have developed a 
research tool, an efficient lentiviral plasmid to visualize and purify 
cancer stem cells, which is useful for screening compounds that 
specifically kill or inhibit cancer stem cells. Cancer stem cells are a 
minority population of cells that initiate and sustain tumors. These 
cells are resistant to therapy and may cause tumors to recur after 
curative treatment. Current therapies generally do not target cancer 
stem cells. The key feature of the plasmid is a reporter system that 
only detects cells expressing the core stem cell transcription factors 
Sox2 and Oct4. The plasmid can identify the putative cancer stem cell 
population through the expression of fluorescent or luminescent 
proteins and has the potential to advance new therapies.
    Potential Commercial Applications:
     Laboratory tool to visualize, quantify and purify cancer 
stem cells.
     Research tool to monitor cancer stem cells in transplanted 
tumors in vivo.
     Research tool to identify cancer stem cells in high 
through-put screening

[[Page 73551]]

of libraries for compounds that specifically inhibit or kill cancer 
stem cells.
     Research tool to optimize therapeutic regimens in 
preclinical models.
     Potential to support precision medicine approach by 
screening therapeutics for efficacy against cancer stem cells in 
patient-derived xenografts.
    Competitive Advantages:
     Efficient visualization of cancer stem cells by functional 
property rather than by use of highly variable cell surface markers.
     Flexible modular Gateway cloning technology allows 
constructs with alternative reporters to be readily generated.
     Approach is independent of cell-of-origin of tumor.
     Cancer stem cell behavior can be monitored in real-time.
    Development Stage:
     Pre-clinical.
     In vitro data available.
     In vivo data available (animal).
    Inventors: Lalage Wakefield and Binwu Tang (NCI).
    Publication: Manuscript under review. Text available on request.
    Intellectual Property: HHS Reference No. E-141-2011/0--Research 
Tool. Patent protection is not being pursued for this technology.
    Licensing Contact: Eggerton Campbell, Ph.D.; 301-435-5282; 
[email protected].
    Collaborative Research Opportunity: The National Cancer Institute, 
Laboratory of Cancer Biology and Genetics, is seeking statements of 
capability or interest from parties interested in collaborative 
research to further develop, evaluate or commercialize a cancer stem 
cell reporter construct for use in drug screens and therapy selection.

AAV-Aquaporin-1 Gene Therapy for Sj[ouml]gren's Syndrome

    Description of Technology: Sj[ouml]gren's syndrome is a chronic 
inflammatory disease affecting over 2 million Americans, whereby 
moisture-producing glands are attacked by the body's immune system. The 
disease is marked by disabling dryness of the mouth and eyes as well as 
fatigue and pain. Researchers at the National Institute of Dental and 
Craniofacial Research have developed a therapy that alleviates 
xerostomia in an animal model of Sj[ouml]gren's syndrome. This 
technology consists of local delivery of adeno-associated virus (AAV) 
mediated aquaporin-1 (AQP1) fusion protein to salivary glands. Using a 
murine model that mimics Sj[ouml]gren's dry mouth symptoms, it was 
discovered that treatment restored salivary fluid movement upon 
expression of AQP1. Targeted delivery of the AAV-AQP1 system makes this 
invention a novel and potential long-term therapeutic for restoration 
of exocrine gland function and prevention of xerostomia-associated pain 
associated with Sj[ouml]gren's syndrome.
    Potential Commercial Applications: Prevention of dry mouth 
(xerostomia) associated with salivary gland dysfunction in patients 
with Sj[ouml]gren's syndrome.
    Competitive Advantages:
     AAV gene transfer to salivary glands is highly efficient.
     AAV-AQP1 promotes de novo salivary flow.
    Development Stage:
     Pre-clinical.
     In vitro data available.
     In vivo data available (animal).
