The patent rights in these inventions have been assigned to the United
States of America.
The prospective exclusive licensed territory may be worldwide and the field
of use may be limited to in vitro diagnostics of prion-associated diseases
requiring FDA premarket approval, or the equivalent thereof outside of the
United States, and USDA licensed veterinary diagnostics, or the equivalents
thereof outside of the United States.
DATES: Only written comments and/or application for a license that are
received by the NIH Office of Technology Transfer on or before 11:59 p.m.
Eastern Time on December 19, 2014 will be considered.
ADDRESSES: Requests for a copy of the patents and applications, inquiries,
comments and other materials relating to the contemplated license should be
directed to: Tedd Fenn, Senior Licensing and Patenting Manager, Office of
Technology Transfer, National Institutes of Health, 6011 Executive Boulevard,
Suite 325, Rockville, MD 20852–3804; Email: fennea@mail.nih.gov; Telephone: 424–297–
0336; Facsimile: 301–402–0220.
SUPPLEMENTARY INFORMATION: The invention relates to methods and
compositions for the detection of infectious prions and diagnosis of prion
related diseases. Currently, available tests for disease-causing prions are
incapable of detecting low concentrations and must be confirmed post-mortem.
This technology enables rapid and economical detection of sublethal
concentrations of prions by using recombinant protein (rPrP-sen) as a marker. A
seeded sample polymerizes rPrP-sen, which is detected as an amplified indicator
of prions in the sample. This assay does not require multiple amplification
cycles unless a higher degree of sensitivity is required. This technology
potentially may be combined with additional prion-detection technologies to
further improve the sensitivity of the assay.
The prospective exclusive license will be royalty bearing and will comply
with the terms and conditions of 35 U.S.C. 209 and 37 CFR Part 404. The
prospective exclusive license may be granted unless within thirty (30) days from
the date of this published notice, the NIH receives written evidence and
argument that establishes that the grant of the license would not be consistent
with the requirements of 35 U.S.C. 209 and 37 CFR Part 404.
Any additional applications for a license in the field of use, filed in
response to this notice, will be treated as objections to the grant of the
contemplated exclusive license. Comments and objections submitted to this notice
will not be made available for public inspection and, to the extent permitted by
law, will not be released under the Freedom of Information Act, 5 U.S.C.

applicant): Human prion diseases are infectious and invariably fatal forms of
neurodegenerative diseases, including sporadic Creutzfeldt-Jakob disease (sCJD),
the most common form, and variant CJD (vCJD) which is associated to consumption
of cattle meat infected by bovine spongiform encephalopathy. Currently there is
not sensitive, objective and non-invasive biochemical diagnosis for these
diseases, and even less a procedure to detect people incubating the disease in
the pre-symptomatic period. This is a major problem for public health, because
prion diseases are known to transmit iatrogenically between human-to-human and
because due to the long pre-symptomatic stage of the disease-which may span five
decades-the asymptomatic carriers far outnumber the clinically affected
individuals. To make the situation even more complicated, the infectious agent
responsible for these diseases, termed prion, is composed exclusively of a
conformationally altered form of a naturally occurring protein, named PrPSc,
which has the unique ability to infect individuals and propagate in the body
without the need for genetic material. PrPSc is not only the infectious agent
and the likely culprit of neurodegeneration, but also the best surrogate marker
for the disease. The challenge is that its quantity is high only in the brain at
late stages of the disease However, compelling evidences indicate that PrPSc is
present in minute amounts in various peripheral tissues and biological fluids.
The main goal of this proposal is to develop a blood- and cerebrospinal fluid
(CSF)-based detection assay for PrPSc associated with sCJD and vCJD. Our
strategy utilizes two pioneering proprietary technologies developed in our lab:
First the protein misfolding cyclic amplification (PMCA) technique which enables
to amplify the amount of PrPSc present in the sample to detect as little as a
single molecule of PrPSc. PMCA, has a similar power of amplification as PCR and
allowed us to detect, for the first time, prions in blood and urine, even at the
pre-symptomatic stages of the disease. Second, PrPSc-specific monoclonal
antibodies (called PrioC) raised against prion-infected brain homogenates in PrP
knock out mice. In this project we will optimize a technology combining PMCA
amplification of PrPSc with detection by sandwich ELISA using the PrioC
conformational antibodies. The assay will be optimized using animal and human
samples for high throughput detection of prions in biological fluids, and will
be validated for sensitivity and specificity according to the requiremets of the
regulatory authorities with the aim to obtain approval for commercialization.
The results generated in this project may lead to the first biochemical test
validated for the diagnosis of CJD. With this validated technology, Amprion will
establish an International Reference Laboratory for the Detection and
Eradication of human prion diseases.

UTHealth researchers discover infectious prion protein in urine of patients
with variant Creutzfeldt-Jakob disease

HOUSTON – (August 7, 2014) – The misfolded and infectious prion protein
that is a marker for variant Creutzfeldt-Jakob disease – linked to the
consumption of infected cattle meat – has been detected in the urine of patients
with the disease by researchers at The University of Texas Health Science Center
at Houston (UTHealth) Medical School.
The results of the international study, led by Claudio Soto, Ph.D.,
professor of neurology at the UTHealth Medical School, is published in the Aug.
7 issue of the New England Journal of Medicine.
Variant Creutzfeldt-Jakob disease in humans and bovine spongiform
encephalopathy in animals – also known as Mad Cow disease – are fatal
neurodegenerative disorders. There are currently no noninvasive tools available
to diagnose the disease and there are no treatments.
Sporadic Creutzfeldt-Jakob disease occurs worldwide at a rate of around 1
new case per million people per year. The variant form is a new disease
occurring in people who either ate the beef of cows with bovine spongiform
encephalopathy or, in the case of three patients in the United Kingdom, received
blood transfusions from asymptomatic infected donors.
The international team of researchers analyzed urine samples from 68
patients with sporadic Creutzfeldt-Jakob disease, 14 patients with variant
Creutzfeldt-Jakob disease, four patients with genetic prion diseases, 50
patients with other neurodegenerative diseases, 50 patients with nondegenerative
neurologic diseases and 52 healthy persons.
Soto’s laboratory used a protein misfolding cyclic amplification assay,
invented in the lab, which mimics the prion replication process in vitro that
occurs in prion disease. The misfolded prion proteins were detected in the urine
of 13 of 14 patients with variant Creutzfeldt-Jakob disease. The single patient
whose urine was negative had been receiving an experimental treatment of
pentosan polysulfate directly into the brain. No misfolded prion proteins were
detected in the urine of any the other study subjects, including the patients
who had sporadic Creutzfeldt-Jakob disease.
“What could be less invasive than detecting this disease in urine? The fact
that we were able to detect just the variant Creutzfeldt-Jakob disease form in
the urine is very important. This could lead to the development of commercial
technology for diagnosis as well as to determine the safety of donated blood and
urinary products,” said Soto, who is the director of The George and Cynthia
Mitchell Center for Research in Alzheimer’s disease and Related Brain Disorders,
and founder of Amprion Inc, a biotech company developing the cyclic
amplification technology for commercial application.
According to the World Health Organization (WHO), variant Creutzfeldt-Jakob
disease affects younger patients, who have a median age of 28 at death, compared
to sporadic Creutzfeldt-Jakob disease with a median age of 68. Most patients,
after diagnosis of either form, live less than a year before death.
As of June 2, 2014, 177 of 229 people in the world with Creutzfeldt-Jakob
disease were from the United Kingdom. A 2013 study published in the British
Medical Journal has estimated that approximately 30,000 people in the United
Kingdom might be carriers of the variant form of the disease.
“This study reports, for the first time, the detection of the abnormal
prion protein in the urine from patients with variant Creutzfeldt-Jakob disease
using the protein misfolding amplification technique pioneered by Dr. Claudio
Soto,” said co-author James W. Ironside, FMedSci, FRSE, professor of clinical
neuropathology at the National CJD Research and Surveillance Unit at the
University of Edinburgh. “This has great potential to allow the development of a
highly sensitive and specific non-invasive test that can be used for the
diagnosis of variant Creutzfeldt-Jakob disease, and potentially as a screening
tool for variant Creutzfeldt-Jakob disease infection in asymptomatic
individuals, which is a topic of current interest in the United Kingdom.”

Background
Prions, the infectious agents responsible for transmissible spongiform
encephalopathies, consist mainly of the misfolded prion protein (PrPSc). The
unique mechanism of transmission and the appearance of a variant form of
Creutzfeldt–Jakob disease, which has been linked to consumption of
prion-contaminated cattle meat, have raised concerns about public health.
Evidence suggests that variant Creutzfeldt–Jakob disease prions circulate in
body fluids from people in whom the disease is silently incubating.
Methods
To investigate whether PrPSc can be detected in the urine of patients with
variant Creutzfeldt–Jakob disease, we used the protein misfolding cyclic
amplification (PMCA) technique to amplify minute quantities of PrPSc, enabling
highly sensitive detection of the protein. We analyzed urine samples from
several patients with various transmissible spongiform encephalopathies (variant
and sporadic Creutzfeldt–Jakob disease and genetic forms of prion disease),
patients with other degenerative or nondegenerative neurologic disorders, and
healthy persons.
Results
PrPSc was detectable only in the urine of patients with variant
Creutzfeldt–Jakob disease and had the typical electrophoretic profile associated
with this disease. PrPSc was detected in 13 of 14 urine samples obtained from
patients with variant Creutzfeldt–Jakob disease and in none of the 224 urine
samples obtained from patients with other neurologic diseases and from healthy
controls, resulting in an estimated sensitivity of 92.9% (95% confidence
interval [CI], 66.1 to 99.8) and a specificity of 100.0% (95% CI, 98.4 to
100.0). The PrPSc concentration in urine calculated by means of quantitative
PMCA was estimated at 1×10−16 g per milliliter, or 3×10−21 mol per milliliter,
which extrapolates to approximately 40 to 100 oligomeric particles of PrPSc per
milliliter of urine.
Conclusions
Urine samples obtained from patients with variant Creutzfeldt–Jakob disease
contained minute quantities of PrPSc. (Funded by the National Institutes of

Background
Definite diagnosis of sporadic Creutzfeldt–Jakob disease in living patients
remains a challenge. A test that detects the specific marker for
Creutzfeldt–Jakob disease, the prion protein (PrPCJD), by means of real-time
quaking-induced conversion (RT-QuIC) testing of cerebrospinal fluid has a
sensitivity of 80 to 90% for the diagnosis of sporadic Creutzfeldt–Jakob
disease. We have assessed the accuracy of RT-QuIC analysis of nasal brushings
from olfactory epithelium in diagnosing sporadic Creutzfeldt–Jakob disease in
living patients.
Methods
We collected olfactory epithelium brushings and cerebrospinal fluid samples
from patients with and patients without sporadic Creutzfeldt–Jakob disease and
tested them using RT-QuIC, an ultrasensitive, multiwell plate–based fluorescence
assay involving PrPCJD-seeded polymerization of recombinant PrP into amyloid
fibrils.
Results
The RT-QuIC assays seeded with nasal brushings were positive in 30 of 31
patients with Creutzfeldt–Jakob disease (15 of 15 with definite sporadic
Creutzfeldt–Jakob disease, 13 of 14 with probable sporadic Creutzfeldt–Jakob
disease, and 2 of 2 with inherited Creutzfeldt–Jakob disease) but were negative
in 43 of 43 patients without Creutzfeldt–Jakob disease, indicating a sensitivity
of 97% (95% confidence interval [CI], 82 to 100) and specificity of 100% (95%
CI, 90 to 100) for the detection of Creutzfeldt–Jakob disease. By comparison,
testing of cerebrospinal fluid samples from the same group of patients had a
sensitivity of 77% (95% CI, 57 to 89) and a specificity of 100% (95% CI, 90 to
100). Nasal brushings elicited stronger and faster RT-QuIC responses than

Transmissible Spongiform Encephalopathy TSE Prion Disease North America
2014
Transmissible Spongiform Encephalopathy TSE Prion Disease have now been
discovered in a wide verity of species across North America. typical C-BSE,
atypical L-type BASE BSE, atypical H-type BSE, atypical H-G BSE, of the bovine,
typical and atypical Scrapie strains, in sheep and goats, with atypical Nor-98
Scrapie spreading coast to coast in about 5 years. Chronic Wasting Disease CWD
in cervid is slowly spreading without any stopping it in Canada and the USA and
now has mutated into many different strains. Transmissible Mink Encephalopathy
TME outbreaks. These Transmissible Spongiform Encephalopathy TSE Prion Disease
have been silently mutating and spreading in different species in North America
for decades.
The USDA, FDA, et al have assured us of a robust Triple BSE TSE prion
Firewall, of which we now know without a doubt, that it was nothing but ink on
paper. Since the 1997 mad cow feed ban in the USA, literally tons and tons of
banned mad cow feed has been put out into commerce, never to return, as late as
December of 2013, serious, serious breaches in the FDA mad cow feed ban have
been documented. The 2004 enhanced BSE surveillance program was so flawed, that
one of the top TSE prion Scientist for the CDC, Dr. Paul Brown stated ; Brown,
who is preparing a scientific paper based on the latest two mad cow cases to
estimate the maximum number of infected cows that occurred in the United States,
said he has "absolutely no confidence in USDA tests before one year ago" because
of the agency's reluctance to retest the Texas cow that initially tested
positive.
see ;
The BSE surveillance and testing have also been proven to be flawed, and
the GAO and OIG have both raised serious question as to just how flawed it has
been (see GAO and OIG reports). North America has more documented TSE prion
disease, in different documented species (excluding the Zoo BSE animals in the
EU), then any other place on the Globe. This does not include the very
likelihood that TSE prion disease in the domestic feline and canine have been
exposed to high doses of the TSE prion disease vid pet food. To date, it’s still
legal to include deer from cwd zone into pet food or deer food. Specified Risk
Material i.e. SRM bans still being breach, as recently as just last month.
nvCJD or what they now call vCJD, another case documented in Texas last
month, with very little information being released to the public on about this
case? with still the same line of thought from federal officials, ‘it can’t
happen here’, so another vCJD blamed on travel of a foreign animal disease from
another country, while ignoring all the BSE TSE Prion risk factors we have here
in the USA and Canada, and the time that this victim and others, do spend in the
USA, and exposed to these risk factors, apparently do not count in any way with
regard to risk factor. a flawed process of risk assessment.
sporadic CJD, along with new TSE prion disease in humans, of which the
young are dying, of which long duration of illness from onset of symptoms to
death have been documented, only to have a new name added to the pot of prion
disease i.e. sporadic GSS, sporadic FFI, and or VPSPR. I only ponder how a
familial type disease could be sporadic with no genetic link to any family
member? when the USA is the only documented Country in the world to have
documented two different cases of atypical H-type BSE, with one case being
called atypical H-G BSE with the G meaning Genetic, with new science now showing
that indeed atypical H-type BSE is very possible transmitted to cattle via oral
transmission (Prion2014). sporadic CJD and VPSPR have been rising in Canada,
USA, and the UK, with the same old excuse, better surveillance. You can only use
that excuse for so many years, for so many decades, until one must conclude that
CJD TSE prion cases are rising. a 48% incease in CJD in Canada is not just a
blip or a reason of better surveillance, it is a mathematical rise in numbers.
More and more we are seeing more humans exposed in various circumstance in the
Hospital, Medical, Surgical arenas to the TSE Prion disease, and at the same
time in North America, more and more humans are becoming exposed to the TSE
prion disease via consumption of the TSE prion via deer and elk, cattle, sheep
and goats, and for those that are exposed via or consumption, go on to further
expose many others via the iatrogenic modes of transmission of the TSE prion
disease i.e. friendly fire. I pondered this mode of transmission via the victims
of sporadic FFI, sporadic GSS, could this be a iatrogenic event from someone
sub-clinical with sFFI or sGSS ? what if?
Two decades have passed since Dr. Ironside first confirmed his first ten
nvCJD victims in 1995. Ten years later, 2005, we had Dr. Gambetti and his first
ten i.e. VPSPR in younger victims. now we know that indeed VPSPR is
transmissible. yet all these TSE prion disease and victims in the USA and Canada
are being pawned off as a spontaneous event, yet science has shown, the
spontaneous theory has never been proven in any natural case of TSE prion
disease, and scientist have warned, that they have now linked some sporadic CJD
cases to atypical BSE, to atypical Scrapie, and to CWD, yet we don’t here about
this in the public domain. We must make all human and animal TSE prion disease
reportable in every age group, in ever state and internationally, we must have a
serious re-evaluation and testing of the USA cattle herds, and we must ban
interstate movement of all cervids. Any voluntary effort to do any of this will
fail. Folks, we have let the industry run science far too long with regards to
the TSE prion disease. While the industry and their lobbyist continues to funnel
junk science to our decision policy makers, Rome burns. ...end
