Methods of Determining the Prognosis of Hepatocellular Carcinoma

    Description of Technology: Hepatocellular carcinoma (HCC) 
represents an extremely poor prognostic cancer that remains one of the 
most common and aggressive malignancies worldwide. A major hallmark of 
HCC is intrahepatic metastasis and post-surgical reoccurrence. With 
current diagnostic methods, HCC patients are often diagnosed with end-
stage cancer and have poor survival. Thus, there is a need for an 
accurate method to identify HCC and its proclivity for metastases/
relapse, particularly at early stages of this disease.
    The inventors have discovered a unique set of microRNA (miRNA) 
biomarkers that are associated with HCC metastasis/recurrence. This 
miRNA signature was validated in an independent cohort of 110 HCC 
samples as an independent predictor of HCC prognosis and likelihood of 
metastasis and relapse. In particular, the inventors provide evidence 
that these miRNA markers can predict HCC metastasis in the early stages 
of cancer. This methodology may enable clinicians to effectively 
stratify patients for appropriate cancer treatment and prioritize liver 
transplantation candidates.
    Applications: (1) Method to prognose HCC, patient survival and 
likelihood of HCC metastasis/relapse; (2) Diagnostic tool to aid 
clinicians in determining appropriate cancer treatment; (3) 
Compositions that inhibit miRNA HCC biomarkers such as siRNA; (4) 
Method to treatment HCC patients with inhibitory miRNA compositions.
    Market: (1) Primary liver cancer accounts for about 2% of cancers 
in the U.S., but up to half of all cancers in some undeveloped 
countries; (2) Post-operative five year survival rate of HCC patients 
is 30-40%.
    Development Status: This technology is currently in the pre-
clinical stage of development.

A Varicella-Zoster Virus Mutant that is Markedly Impaired for Latent 
Infection Available for the Development of Shingles Vaccines and 
Diagnostics

    Description of Technology: Reactivation of latent Varicella-Zoster 
virus (VZV) infection is the cause of shingles, which is prominent in 
adults over the age of 60 and individuals who have compromised immune 
systems, due to HIV infection, cancer treatment and/or transplant. 
Shingles is a worldwide health concern that affects approximately 
600,000 Americans each year. The incidence of shingles is also high in 
Europe, South America, and India; the latter having an estimated two 
million individuals affected, yearly. Recent research studies show that 
VZV vaccines have a significant effect on decreasing the incidence of 
shingles in elderly.
    The current technology describes compositions, cells and methods 
related to the production and use of a mutant VZV and the development 
of vaccines against the infectious agent. Latent VZV expresses a 
limited repertoire of viral genes including the following six open 
reading frames (ORFs): 4, 21, 29, 62, 63, and 66. The present invention 
describes an ORF29 mutant VZV that demonstrates a weakened ability to 
establish latency in animal studies. The current technology provides 
methods for using the mutant in the development of live vaccines and 
diagnostic tools. A related invention is described in PCT/US05/021788 
(publication number WO2006012092).
    Applications: Development of vaccines and diagnostics for 
prevention of shingles.
    Development Status: Pre-clinical studies have been performed to 
demonstrate the reduced latency of the ORF29 mutant VZV in animals.
    Inventors: Jeffrey Cohen (NIAID) and Lesley Pesnicak (NIAID).
    Patent Status: U.S. Provisional Application No. 60/857,766 filed 09 
Nov 2006 (HHS Reference No. E-029-2007/0-US-01).
    Licensing Availability: Available for licensing and commercial 
development.

Highly Soluble Pyrimido-Dione-Quinoline Compounds: Small Molecules That 
Stabilize and Activate p53 in Transformed Cells

    Description of Technology: The tumor-suppressor p53 protein plays a 
major role in tumor development. Most human cancers ail to normally 
activate p53, which is at least partly responsible for the unregulated 
growth of cancer cells and their failure to undergo apoptosis. While 
many chemotherapeutics enhance p53 levels, their non-specific DNA 
damage (genotoxicity) causes unfavorable side effects.
    This invention reports the composition and function of a pyrimido-
dione-quinoline that was found to inhibit HDM2's ubiquitin ligase (E3) 
activity without the accompanying genotoxicity of current therapeutic 
drugs. Like the HLI98 family of compounds reported previously (see 
reference below), the subject of the current invention stabilizes p53 
in cells, inhibiting its ubiquitin-mediated proteasomal degradation. 
Unlike the HLI98 compound, the pyrimido-dione-quinoline reported here 
induces a robust p53 response, and is highly water-soluble. Thus, these 
pyrimido-dione-quinoline compounds have the potential to stabilize p53 
and activate a p53 response in tumors.
    Applications and Modality: Water-soluble with improved potency in 
stabilizing p53 and activating a p53 response; Inhibits unregulated 
growth of cancer cells; Reduced genotoxicity compared to many 
chemotherapeutics.
    Market: Small molecule-based cancer therapeutics for tumors 
expressing wild type p53, which comprises approximately 50% of cancers.
    Development Status: The technology is currently in the pre-clinical 
stage of development.

Human Cancer Therapy Using Engineered Anthrax Lethal Toxin

    Description of Technology: Anthrax lethal toxin (LeTx) consists of 
two components: The protective antigen (PrAg) and the lethal factor 
(LF). PrAg binds to the cell surface where it is activated by furin 
protease, followed by the formation of a PrAg heptamer. LF is then 
translocated into the cytosol of a cell via this heptamer, where it 
acts as a metalloprotease on all but one mitogen-activated protein 
kinase kinase (MAPKK). Approximately 70% of human melanomas contain a 
mutation (B-RAF V600E) that constitutively activates a MAPKK pathway, 
and LeTx has been shown to have significant toxicity towards cells 
which have this mutation. This suggested a potential use for LeTx in 
cancer therapy. Unfortunately, native LeTx is toxic to normal cells, 
detracting from its in vivo applicability.
    PrAg has been engineered to be activated by a matrix 
metalloprotease (MMP), instead of by furin protease. Because MMPs are 
highly expressed in tumor cells, this modification increases 
selectivity towards cancer cells. Surprisingly, mouse data shows that 
the modified LeTx (denoted PrAg-L1/LF) is less cytotoxic to ``normal'' 
cells in vivo, when compared to wild-type LeTx. Significantly, PrAg-L1/
LF maintained its high toxicity toward human tumors in mouse xenograft 
models of human tumors, including melanomas. However, this toxicity 
applied not only to tumors having mutations that constitutively 
activate MAPKKs, but also to other tumor types such as lung and colon 
carcinomas. The absence of toxicity to ``normal'' cells coupled to its 
effectiveness on a wide range of cancer cell types suggests that PrAg-
L1/LF may represent a novel cancer therapeutic.
    Applications: PrAg-L1/LF has applications as a human cancer 
therapeutic; Applicability extends beyond melanomas, including lung and 
colon carcinomas.
    Market: The worldwide market for melanoma therapeutics is 
approximately $437M, and is predicted to reach $680M by the year 2009. 
Approximately 2.4 million people are afflicted with melanoma, with 
around 150,000 new cases each year. Demonstration of effectiveness in 
vivo for lung and colon carcinomas will increase the market for this 
technology.
    Development Status: The technology is at the preclinical stage.
