Use of Razoxane for the Treatment of Alzheimer's Disease

    Description of Technology: Abnormalities in the metabolism of the 
transition metals, iron and copper, have been demonstrated to play a 
crucial role in the pathogenesis of various neurodegenerative diseases, 
including Alzheimer's disease (AD) and Parkinson's disease (PD). 
Excessive iron accumulation in the brain occurs in both AD and PD. High 
levels of reactive iron can increase oxidative stress-induced neuronal 
vulnerability, increase the toxicity of environmental or endogenous 
toxins, and accelerate hallmark pathologies of these diseases.
    As an example among many, the expression level of amyloid-[beta] 
precursor protein (APP) that generates the AD neurotoxic peptide, 
amyloid-[beta] (A[beta]), is

[[Page 53429]]

regulated in large part by iron levels. APP mRNA has an iron response 
element (IRE) in its 5'-untranslated region, and cleavage of APP to 
release different amyloidogenic and non-amyloidogenic peptide forms 
involves metalloproteases.
    Elevated A[beta] levels as well as plaques formed by aggregation of 
A[beta] involve iron, and play a significant role in degeneration of 
the brain seen in AD. Chelators can reduce both the generation and 
aggregation of A[beta]. Razoxane, a bisdioxopiperazine, is an orally 
active metal chelator approved for the treatment of cancer, where it 
and dexrazoxane have been effectively used for decades. In neuronal 
cell culture models, razoxane induced dose-dependent reductions in APP 
and A[beta] levels without toxicity. In animal experiments (transgenic 
mice expressing human A[beta]), razoxane substantially reduced A[beta] 
1-40 and 1-42 in brain by up to 46% without toxicity following once 
daily, 21 day administration.
    The claimed invention is the novel use of razoxane and other 
bisdioxopiperazines to reduce amyloid-beta peptide levels, reduce 
aggregation of alpha-synuclein and tau protein, and reduce abnormal 
protein folding or aggregation for the treatment of AD and related 
diseases with protein aggregation pathology. Since razoxane has been 
approved for humans use, it could be more quickly developed as a 
treatment for AD, PD and other diseases.
    Market:
    <bullet> Up to 4.5 million Americans are estimated to suffer from 
AD, which usually strikes after the age of 60.
    <bullet> Population longevity is increasing so AD is expected to be 
a growing health problem.
    <bullet> Currently marketed drugs only delay the severity of AD so 
better solutions are needed.
    Development Status: Clinical safety data and pre-clinical efficacy 
data for treatment of Alzheimer's disease.

Prevention and Treatment of Multiple Sclerosis (MS) by Administering E-
Selectin

    Description of Technology: The invention is a method and 
composition for inhibiting or treating symptoms of inflammatory 
demyelination or inflammation associated with autoimmune disorders. 
This is accomplished by administering recombinant E-selectin protein 
intranasally and resulting in E selectin-specific regulatory T-cells. 
These regulatory T-cells suppress activation of blood vessels where E-
selectin is normally expressed by the localized production of 
immunosuppressive cytokines, modulating the actions of otherwise pro-
inflammatory T-cells that can aberrantly cause demyelination of 
neurons, which leads to diseases like MS.
    Applications: In addition to MS, potentially effective in treating 
other autoimmune disorders such as rheumatoid arthritis, type 1 
diabetes, psoriasis, and those that affect blood vessels.
    Market: MS may affect more than 2.5 million people worldwide. 
Currently, it is estimated that approximately 400,000 Americans are 
afflicted with MS and 200 more are diagnosed weekly.
    Development Status: In vitro and in vivo data are available.
    Inventors: Jacqueline Shukaliak-Quandt et al. (NINDS).

    <bullet> PCT Application No. PCT/2007/021682 filed 09 Oct 2007 (HHS

Use of Pentosan Polysulfate To Treat Certain Conditions of the Prostate

    Description of Technology: Benign prostatic hyperplasia (BPH), 
involving a proliferation of smooth muscle cells and increased 
deposition of extracellular matrix, is a common development: 50% of men 
over age 60 (about 12.5 million men), and as much as 80% of all men 
over age 80 (about 3.2 million men), have some enlargement of the 
prostate gland.
    This technology is a method for treating BHP using the oral 
medication, pentosan polysulfate. Pentosan polysulfate is a well known 
semi-synthetic polysaccharide extracted from beech wood cellulose that 
is FDA approved for the treatment of interstitial fibrosis. The current 
technology builds on the surprising discovery that pentosan polysulfate 
can cause regression of scarring and lesions in prostatic tissue. 
Pentosan polysulfate reduces or eliminates both smooth muscle cell 
proliferation and extracellular matrix deposition, and thus reduces the 
size of the prostate gland and associated obstructive symptoms.
    Applications and Advantages:
    <bullet> A method of treating benign prostatic hyperplasia using 
pentosan polysulfate.
    <bullet> The method treats the underlying pathology of BHP non-
invasively.
    <bullet> The method addresses associated conditions, such as 
chronic prostatitis, prostadynia, and irritative bladder conditions 
(other than interstitial cystitis).
    <bullet> Pentosan polysulfate has been FDA approved for another 
use.
    Development Status: In vitro studies on BPH biopsy samples that 
demonstrate the drug slows the growth of prostate cells and 
extracellular matrix have been completed.
    Patent Status: U.S. Patent No. 6,828,309 issued 07 Dec 2004 (HHS 
Reference No. E-104-1997/0-US-03).
    Inventor: Gary E. Striker (NIDDK).

prostate smooth muscle proliferation and extracellular matrix turnover.
