GPR116 Knockout and Conditional Knockout Mice

    Description of Technology: Pulmonary surfactant plays a critical 
role in preventing alveolar collapse by decreasing surface tension at 
the alveolar air-liquid interface. Surfactant deficiency contributes to 
the pathogenesis of acute lung injury (ALI) and acute respiratory 
distress syndrome (ARDS), common disorders that can afflict patients of 
all ages and carry a mortality rate greater than 25%. Excess surfactant 
leads to pulmonary alveolar proteinosis. The NCI investigators created 
a G-protein coupled receptor GPR116 mutant mouse model and showed that 
GPR116 plays a previously unexpected, essential role in maintaining 
normal surfactant levels in the lung.
    The mouse model could aid in the development of drug screens to 
identify agents that can modulate surfactant levels. Alveolar type II 
cells have also been isolated from the GPR116 wildtype and knockout 
mice that could be directly used in such assays. The identification of 
surfactant modulating agents could be important to a number of lung 
surfactant disorders.
    Potential Commercial Applications: Research materials to study lung 
surfactant homeostasis and disorders.
    Competitive Advantages: Not available elsewhere.
    Development Stage:
     In vitro data available.
     In vivo data available (animal).

Engineered Anthrax Toxin Variants That Target Cancer

    Description of Technology: This technology describes the use of 
novel mutated anthrax protective antigen (PA) protein variants to 
target tumor cells and tumor vasculature. NIH scientists have 
engineered two PA variants that selectively complement one another and 
combine to form active octamers that target tumor cells. This 
controlled oligomeric activation of the PA proteins makes the 
likelihood of toxicity to non-tumor cells very low since non-tumor 
tissue does not express certain cell-surface proteases required to 
activate the PA variants. Using proteases that are highly expressed in 
tumor cells, e.g., matrix metalloproteases (MMP) and urokinase 
plasminogen activator (uPA), the scientists have shown significant 
tumor growth suppression with the oligomer in a mouse model. 
Furthermore, other tumor-specific proteases could also be used to 
control formation of the targeted octameric anthrax toxin structures. 
Moreover, the structures can be expanded to include several PA 
variants. In summary, this technology provides a unique, expandable 
platform that reduces toxicity to normal tissues compared to other 
systems and can be used to treat cancers more effectively.
    Potential Commercial Applications: Therapeutic treatment for solid 
tumors, cancers, and infectious diseases.
    Competitive Advantages:
     Specificity in targeting tumors while eliminating side 
effects associated with non-specific targeting of normal cells.
     Method can be expanded to include different proteases and 
up to eight PA variants.
    Development Stage:
     In vitro data available.
     In vivo data available (animal).

Method of Inducing Pluripotent or Multipotent Stem Cells by Blocking 
CD47 Receptor Signaling

    Description of Technology: NIH researchers have discovered that 
blockade of the signaling activity of a single cell-surface receptor, 
CD47, without transfection or introduction of potentially transforming 
viral vectors, results in high frequency, spontaneous generation of 
self-renewing cells with a high proliferative capacity. Induced 
pluripotent stem cells (iPS cells) are currently produced by 
transforming cells with viral or other constitutive expression vectors 
encoding four stem cell transcription factors (c-Myc, Sox2, Klf4, and 
Oct4), but this method presents challenges such as over-expression of 
c-Myc, which can result in malignant transformation. The present 
invention relates to a method of using CD47-modulating compounds to 
induce multipotent stem cells without the concomitant risk of malignant 
transformation and without requiring the use of feeder cells. The 
cellular phenotypes are associated with increased expression of the 
hallmark stem cell-inducing transcription factors, c-Myc, Sox2, Klf4, 
and Oct4. The current invention builds on the NIH's previous 
discoveries of antibodies, antisense morpholino oligonucleotides, 
peptide compounds and other small molecules that modulate CD47.
    Potential Commercial Applications: Regenerative medicine and stem 
cell therapy.
    Competitive Advantages:
     Does not require use of viral vectors.
     Eliminates risk of malignant transformation for clinical 
     Eliminates need for feeder cells.
     Allows generation and maintenance of a ready supply of iPS 
cells using a single defined agent.
     Avoids loss of differentiated phenotype associated with 
telomerase or T antigen transfection.
    Development Stage:
     In vitro data available.
     In vivo data available (animal).

Human Monoclonal Antibodies to Glypican-3 Protein and Heparan Sulfate 
for Treatment of Cancer

    Description of Technology: Hepatocellular carcinoma (HCC) is the 
most common form of liver cancer, and is among the more deadly cancers 
in the world due to its late detection and poor prognosis. No effective 
treatment is available for liver cancer therapy.
    Glypican-3 (GPC3) is a cell surface protein that is preferentially 
expressed on HCC cells, making it an attractive potential target for 
developing a therapeutic. This invention concerns human monoclonal 
antibodies against GPC3 and their use for the treatment of GPC3-
expressing cancers such as HCC.
    Specifically, the inventors have generated two distinct human 
monoclonal antibodies to GPC3. The first antibody (HN3) binds to a 
conformational epitope on the cell surface domain of GPC3. The second 
antibody (HS20) binds specifically to heparan sulfate chains on GPC3. 
These antibodies can inhibit the growth of HCC cells, thereby 
decreasing the ability of tumors to grow and metastasize. Furthermore, 
by using the antibodies to target a toxic moiety to only those cells 
that express GPC3, cancer cells can be eliminated while allowing 

[[Page 37556]]

essential cells to remain unharmed. Thus, monoclonal antibodies to GPC3 
(and corresponding immunotoxins) represent a novel therapeutic 
candidate for treatment of HCC, as well as other cancers associated 
with the differential expression of GPC3.
    Potential Commercial Applications:
     Therapeutic antibodies against cancers that overexpress 
     Therapeutic immunotoxins or antibody-drug conjugates for 
killing cancer cells that overexpress GPC3.
     Diagnostics for detecting cancers associated with GPC3 
     Specific cancers include hepatocellular cancer (HCC), 
melanoma, ovarian cancer, thyroid cancer, lung squamous cell carcinoma, 
Wilms' tumor, neuroblastoma, hepatoblastoma, and testicular germ-cell 
    Competitive Advantages:
     Monoclonal antibodies create a level of specificity that 
can reduce deleterious side-effects.
     Multiple treatment strategies available including the 
killing of cancer cells with a toxic agent or by inhibiting cell 
     Non-invasive and potentially non-liver toxic alternative 
to current HCC treatment strategies.
    Development Stage:
     In vitro data available.
     In vivo data available (animal).
