Federal Register / Vol. 70, No. 56 / Thursday, March 24, 2005 / Notices
relation to the referral of Medicare
beneficiaries to a durable medical
equipment company, in violation of the
Medicare antikickback law (42 U.S.C.
1320a–7b), and in violation of 18 U.S.C.
371. The court sentenced Dr. Caro to 2
years probation for the offense (United
States v. Eduardo Caro, Docket No.
00CR020–05 (SEC) (D.P.R. July 13,
2001)).
At the time of Dr. Caro’s criminal
actions, he was a physician authorized
to practice medicine in Puerto Rico as
a Medicare provider and was authorized
to prescribe, among other things,
durable medical equipment to Medicare
beneficiaries. The owner of a durable
medical equipment company,
authorized to sell to Medicare
beneficiaries, offered and paid money to
Dr. Caro to unlawfully induce him to
refer patients to the medical equipment
company. Dr. Caro received money in
return for referring patients to the
company for the furnishing of durable
medical equipment and services payable
under the Medicare program, the
specific amount depending on the value
of the service or equipment referred to
the company. The unlawful kickback
payments made to Dr. Caro allowed the
company to improperly invoice
Medicare for approximately $11,940.
In addition, Dr. Caro demonstrated a
pattern of conduct sufficient to find
reason to believe that he may violate
requirements under the act relating to
drug products. In July 2002, FDA issued
Dr. Caro a Notice of Disqualification to
Receive Investigational New Drugs. This
action was based upon repeated and
deliberate submissions of false
information to drug sponsors in
required reports for studies of
investigational new drugs that are
subject to section 505 of the act. In
addition, Dr. Caro repeatedly and
deliberately failed to comply with
regulations governing the conduct of
clinical investigators and the use of
investigational new drugs in conducting
two protocols sponsored by Daiichi
Pharmaceutical Corp. Among other
things, he submitted false information
in required reports, deviated from
protocols, maintained inaccurate and
inadequate study records, failed to
report adverse events, failed to properly
account for the disposition of study
medications, failed to obtain adequate
institutional review board approval, and
failed to obtain proper consent from
study subjects or their legally
authorized representatives. As a result,
he is no longer entitled to receive
investigational new drugs (Notice of
Disqualification to Receive
Investigational New Drugs, July 30,
2002).

As a result of Dr. Caro’s conviction
and pattern of conduct, FDA served him
by certified mail on February 18, 2004,
a notice proposing to debar him for 5
years from providing services in any
capacity to a person that has an
approved or pending drug product
application. The proposal also offered
Dr. Caro an opportunity for a hearing on
the proposal. The proposal was based
on a finding, under section
306(b)(2)(B)(ii) of the act (21 U.S.C.
335a(b)(2)(B)(ii)), that Dr. Caro was
convicted of a felony under Federal law
for engaging in a conspiracy to defraud
the United States and has demonstrated
a pattern of conduct sufficient to find
that there is reason to believe that he
may violate requirements under the act
relating to drug products. Dr. Caro was
provided 30 days to file objections and
request a hearing. Dr. Caro did not
request a hearing. His failure to request
a hearing constitutes a waiver of his
opportunity for a hearing and a waiver
of any contentions concerning his
debarment.
II. Findings and Order
Therefore, the Director, Center for
Drug Evaluation and Research, under
section 306(b)(2)(B)(ii) of the act and
under authority delegated to him (Staff
Manual Guide 1410.035), finds that Dr.
Eduardo Caro Acevedo has been
convicted of a felony under Federal law
for engaging in a conspiracy to defraud
the United States and has demonstrated
a pattern of conduct sufficient to find
that there is reason to believe that he
may violate requirements under the act
relating to drug products.
As a result of the foregoing findings,
Dr. Caro is debarred for 5 years from
providing services in any capacity to a
person with an approved or pending
drug product application under sections
505, 512, or 802 of the act (21 U.S.C.
355, 360b, or 382), or under section 351
of the Public Health Service Act (42
U.S.C. 262), effective March 24, 2005
(see sections 306(c)(1)(B) and
(c)(2)(A)(iii) and 201(dd) of the act (21
U.S.C. 321(dd))). Any person with an
approved or pending drug product
application who knowingly uses the
services of Dr. Caro, in any capacity,
during his period of debarment, will be
subject to civil money penalties (section
307(a)(6) of the act (21 U.S.C.
355b(a)(6))). If Dr. Caro, during his
period of debarment, provides services
in any capacity to a person with an
approved or pending drug product
application, he will be subject to civil
money penalties (section 307(a)(7) of the
act). In addition, FDA will not accept or
review any abbreviated new drug
applications submitted by or with the

Any application by Dr. Caro for
termination of debarment under section
306(d)(4) of the act should be identified
with Docket No. 2001N–0541 and sent
to the Division of Dockets Management
(see ADDRESSES). All such submissions
are to be filed in four copies. The public

This invention relates to humanized
monoclonal antibodies that bind to the
tumor antigen carcinoembryonic antigen
(CEA). More specifically, the present
technology relates to humanized COL–
1 antibodies that have minimal
immunogenicity and retain antigenbinding affinity for CEA. CEA is over
expressed in 95% of gastrointestinal and
pancreatic tumors. Because CEA is over
expressed consistently, it is anticipated
that CEA would be an excellent target
for an antibody-based therapeutics.
The invention also discloses a novel
method for humanizing monoclonal
antibodies. This humanization method
encompasses grafting xenogenic
Specificity Determining Regions (SDRs)
onto Complementarity Determining
Regions (CDR) templates derived from
several different human germline
sequences. The use of several different
human germline sequences greatly
reduces the potential for
immunogenicity and greatly minimizes
the number of SDRs required for
equivalent or better antigen binding of
the antibody.
This humanization method is
applicable to development of antibodies
to any immunogenic epitopes.
In addition to licensing, the
technology is available for further
development through collaborative
research opportunities with the
inventors.
Modulating p38 Kinase Activity

PCT Application filed 04 Feb 2005

PCT–01)

Protein kinases are involved in
various cellular responses to
extracellular signals. The protein kinase
termed p38 is also known as cytokine
suppressive anti-inflammatory drug
binding protein (CSBP) and RK. It is
believed that p38 has a role in
mediating cellular response to
inflammatory stimuli, such as leukocyte
accumulation, macrophage/monocyte
activation, tissue resorption, fever, acute
phase responses and neutrophilia. In
addition, p38 has been implicated in
cancer, thrombin-induced platelet
aggregation, immunodeficiency
disorders, autoimmune diseases, cell
death, allergies, osteoporosis and
neurodegenerative disorders.
This invention includes compositions
and methods for controlling the activity
VerDate jul<14>2003
15:04 Mar 23, 2005
Jkt 205001
of p38 specifically in T cells through an
alternate activation pathway. By
controlling p38 activity through
interference with this alternate pathway,
the T cells themselves can be controlled
which in turn can be a treatment for
conditions or diseases characterized by
T cell activation such as autoimmune
diseases, transplant rejection, graftversus-host disease, systemic lupus
erythematosus, and viral infections such
as HIV infections. One major benefit for
this invention is the development of
small molecular inhibitors of the
alternative p38 activation pathway (i.e.
Gadd45a-mimetics). The inventors have
found that Gadd45a specifically inhibits
the activity of p38 phosphorylated on
Tyr-323. p38 activated by MKK6 (which
phosphorylates Thr-180/Tyr-182) is
found not to be inhibited by Gadd45a.
This emphasizes the specific nature of
the activating modification and its
regulation by Gadd45a, including its
suitability as a tissue-specific molecular
target.

The researchers produced
heterozygous and homozygous mu
opiate receptor knockout mice that
displayed 54% and 0% of wild-type
levels of mu opiate receptor expression,
respectively. These knockout mice were
generated by injecting 15–20
homologous, recombinant ES cells into
blastocysts harvested from C57BL/6J
mice and by implanting the blastocysts
into the uteri of pseudopregnant CD–1
mice.
Morphine acts on opiate receptors
found on spinal and supraspinal
neurons in the central nervous system.
There are three main subtypes of these
receptors, mu, kappa, delta. Morphine
produces an analgesic effect by acting
through these receptors, especially the
mu receptor. However, the roles played

by each of these receptors in pain
processing in either drug-free or
morphine-treated states are not clear. A
mu opiate receptor knockout mouse
model can be used to elucidate
mechanistic and behavioral roles of this
receptor subtype.

Tryptophan as a Functional
Replacement for ADP-ribose-arginine in
Recombinant Proteins
Joel Moss et al. (NHLBI)
U.S. Patent Application No. 10/517,565

160–2002/0–US–03), claiming priority

Bacterial toxins such as cholera toxin
and diphtheria toxin catalyze the ADPribosylation of important cellular target
proteins in their human hosts, thereby,
as in the case of cholera toxin,
irreversibly activating adenylyl cyclase.
In this reaction, the toxin transfers the
ADP-ribose moiety of Nicotinamide
Adenine Dinucleotide (NAD) to an
acceptor amino acid in a protein or
peptide. ADP-ribosylation leads to a
peptide/protein with altered
biochemical or pharmacological
properties. Mammalians proteins
catalyze reactions similar to the
bacterial toxins. The ADP-ribosylated
proteins represent useful
pharmacological agents, however, their
use is limited by the inherent instability
of the ADP-ribose-protein linkage.
The NIH announces a new technology
wherein recombinant proteins are
created that substitute tryptophan for an
arginine, thereby making the protein
more stable, and better suited as agents
for therapeutic purposes. The
modification creates an effect similar to
ADP-ribosylation of the arginine. An
example of a protein that can be
modified is the defensin molecule,
which is a broad-spectrum antimicrobial
that acts against infectious agents and
plays an important role in the innate
immune defense in vertebrates.

technology is available for further

Available for licensing are methods
and devices for selective delivery of
therapeutic substances to specific
histologic or microanatomic areas of
organs (introduction of the therapeutic
substance into a hollow organ space
(such as an hepatobiliary duct or the
gallbladder lumen) at a controlled
pressure, volume or rate allows the
substance to reach a predetermined
cellular layer (such as the epithelium or
sub-epithelial space). The volume or
flow rate of the substance can be
controlled so that the intralumenal
pressure reaches a predetermined
threshold level beyond which
subsequent subepithehal delivery of the
substance occurs. Alternatively, a lower
pressure is selected that does not exceed
the threshold level, so that delivery
occurs substantially only to the
epithelial layer. Such site-specific
delivery of therapeutic agents permits
localized delivery of substances (for
example to the interstitial tissue of an
organ) in concentrations that may
otherwise produce systemic toxicity.
Occlusion of venous or lymphatic
drainage from the organ can also help
prevent systemic administration of
therapeutic substances, and increases
selective delivery to superficial
epithelial cellular layers. Delivery of
genetic vectors can also be better
targeted to cells where gene expression
is desired. The access device comprises
a cannula with a wall piercing tracar
within the lumen. Two axially spaced
inflatable balloons engage the wall
securing the cannula and sealing the
puncture site. A catheter equipped with
an occlusion balloon is guided through
the cannula to the location where the
therapeutic substance is to be delivered.

Modulating p38 Kinase Activity

mu opiate receptor expression, respectively. These knockout mice were
generated by injecting 15-20 homologous, recombinant ES cells into
blastocysts harvested from C57BL/6J mice and by implanting the
blastocysts into the uteri of pseudopregnant CD-1 mice.
Morphine acts on opiate receptors found on spinal and supraspinal
neurons in the central nervous system. There are three main subtypes of
these receptors, mu, kappa, delta. Morphine produces an analgesic
effect by acting through these receptors, especially the mu receptor.
However, the roles played by each of these receptors in pain processing
in either drug-free or morphine-treated states are not clear. A mu
opiate receptor knockout mouse model can be used to elucidate
mechanistic and behavioral roles of this receptor subtype.

Bacterial toxins such as cholera toxin and diphtheria toxin
catalyze the ADP-ribosylation of important cellular target proteins in
their human hosts, thereby, as in the case of cholera toxin,
irreversibly activating adenylyl cyclase. In this reaction, the toxin
transfers the ADP-ribose moiety of Nicotinamide Adenine Dinucleotide
(NAD) to an acceptor amino acid in a protein or peptide. ADP-
ribosylation leads to a peptide/protein with altered biochemical or
pharmacological properties. Mammalians proteins catalyze reactions
similar to the bacterial toxins. The ADP-ribosylated proteins represent
useful pharmacological agents, however, their use is limited by the
inherent instability of the ADP-ribose-protein linkage.
The NIH announces a new technology wherein recombinant proteins are
created that substitute tryptophan for an arginine, thereby making the
protein more stable, and better suited as agents for therapeutic
purposes. The modification creates an effect similar to ADP-
ribosylation of the arginine. An example of a protein that can be
modified is the defensin molecule, which is a broad-spectrum
antimicrobial that acts against infectious agents and plays an
important role in the innate immune defense in vertebrates.

Available for licensing are methods and devices for selective
delivery of therapeutic substances to specific histologic or
microanatomic areas of organs (introduction of the therapeutic
substance into a hollow organ space (such as an hepatobiliary duct or
the gallbladder lumen) at a controlled pressure, volume or rate allows
the substance to reach a predetermined cellular layer (such as the
epithelium or sub-epithelial space). The volume or flow rate of the
substance can be controlled so that the intralumenal pressure reaches a
predetermined threshold level beyond which subsequent subepithehal
delivery of the substance occurs. Alternatively, a lower pressure is
selected that does not exceed the threshold level, so that delivery
occurs substantially only to the epithelial layer. Such site-specific
delivery of therapeutic agents permits localized delivery of substances
(for example to the interstitial tissue of an organ) in concentrations
that may otherwise produce systemic toxicity. Occlusion of venous or
lymphatic drainage from the organ can also help prevent systemic
administration of therapeutic substances, and increases selective
delivery to superficial epithelial cellular layers. Delivery of genetic
vectors can also be better targeted to cells where gene expression is
desired. The access device comprises a cannula with a wall piercing
tracar within the lumen. Two axially spaced inflatable balloons engage
the wall securing the cannula and sealing the puncture site. A catheter
equipped with an occlusion balloon is guided through the cannula to the
location where the therapeutic substance is to be delivered.
