SUPPLEMENTARY INFORMATION:
ADDRESSES:
I. Background
In the Federal Register of January 30,
1998 (63 FR 4571), FDA published a
final rule that revised 21 CFR 814.44(d)
and 814.45(d) to discontinue individual
publication of PMA approvals and
denials in the Federal Register,
providing instead to post this
information on the Internet at https://
www.fda.gov. In addition, the
regulations provide that FDA publish a
quarterly list of available safety and
effectiveness summaries of PMA
approvals and denials that were
announced during the quarter. FDA
believes that this procedure expedites
public notification of these actions
because announcements can be placed
on the Internet more quickly than they
can be published in the Federal
Register, and FDA believes that the
Internet is accessible to more people
than the Federal Register.
In accordance with section 515(d)(4)
and (e)(2) of the Federal Food, Drug, and
Cosmetic Act (the act) (21 U.S.C.
360e(d)(4) and (e)(2)), notification of an
order approving, denying, or
withdrawing approval of a PMA will
continue to include a notice of
opportunity to request review of the
order under section 515(g) of the act.
The 30-day period for requesting
administrative reconsideration of an
FDA action under § 10.33(b) (21 CFR
10.33(b)) for notices announcing
approval of a PMA begins on the day the
notice is placed on the Internet. Section
10.33(b) provides that FDA may, for
good cause, extend this 30-day period.
Reconsideration of a denial or
withdrawal of approval of a PMA may
be sought only by the applicant; in these
cases, the 30-day period will begin
when the applicant is notified by FDA
in writing of its decision.
The following is a list of PMAs
approved by CBER for which summaries
of safety and effectiveness were placed
on the Internet from October 1, 2004,
through December 31, 2004. There were
no denial actions during the period. The
list provides the manufacturer’s name,
the product’s generic name or the trade
name, and the approval date.

beta-Catenin Splice Variants
Mark J. Roth and Konrad Huppi (NCI);
U.S. Provisional Application No. 60/
652,154 filed 10 Feb 2005 (DHHS
Reference No. E–018–2005/0–US–01);
Licensing Contact: Susan S. Rucker;
(301) 435–4478; ruckersu@mail.nih.gov.
This application relates to methods
for early detection, diagnosis, and
prognosis of cancers and their
associated preneoplastic lesions. The
methods are useful in evaluating the
status of preneoplastic lesions as well as
tumor tissue. Because of this, the
methods can be used to track the
progression and therapeutic response of
disease in cell and tissue samples of
normal, dysplasia or cancerous
epithelium procured by routine
cytology, i.e., exfoliated/brush or fine
needle aspiration, or surgical methods.
The methods are particularly useful
with respect to adenocarcinomas and
squamous cell carcinomas. In particular,
the methods described and claimed in
the application are useful with respect
to preneoplasias and carcinomas
involving the upper aerodigestive tract.
The methods involve the
measurement of levels of one or more
pairs of transcripts or the protein
products of these pairs of transcripts or
the cellular localization of the
transcripts or proteins. The primary
transcripts or protein products useful in
this method are those of the betaCatenin gene (CTNNB1). In particular,
the levels of the 16A and 16B CTNNB1
transcripts or protein products are of
importance in carrying out the methods
of this patent application. Other gene
transcripts or protein products that may
be used in conjunction with CTNNB1
16A and 16B to provide additional
information are WAF1 (p21) and cMYC.
The methods can be practiced using
fresh or frozen cell and/or tissue
specimens and techniques such as laser
capture microdissection (LCM) RT–PCR.
In addition to licensing, the
technology is available for further
development through collaborative
research opportunities with the
inventors.

Carcinoembryonic antigen (CEA) has
been found to be an important marker
of colorectal cancer. CEA is expressed in
85 percent of all gastric cancers and may
function as a metastatic potentiator of
such cancers. In addition, it has been
shown that CEA is up regulated when
certain cancers are treated with standard
chemotherapy drugs. A treatment
modality that focuses specifically on
CEA could be an effective way of
treating many carcinomas, including
colorectal, gastric, pancreatic, lung and
breast cancers.
The present invention relates to
humanized monoclonal antibodies that
bind to CEA. Specifically, these
antibody variants have amino acid
substitutions in the heavy chain
framework that reduces the likelihood
of human anti-mouse antibodies
(HAMA).
The original murine COL–1 antibody
has been shown to be reactive to CEA
without cross reactivity with other
potential antigens of the CEA family:
specifically Antigens NCA–1 and

normal fecal antigen Ag1. The increased
specificity to CEA and reduced human
immunogenicity of these COL–1
humanized variants makes these
antibodies attractive therapeutic and/or
diagnostic compounds.
The COL–1 antibody is described in
the following background publications:

Inhibiting IL–13 Receptor-Expressing
Cancer Cells With Anti-IL–13 Receptor
Immunotoxin and Alkylating Agents
Raj Puri and Syed Husain (FDA); U.S.

E–302–2003/0–US–01); Licensing
Contact: Brenda Hefti; (301) 435–4632;
heftib@mail.nih.gov.
The present invention relates to
methods of inhibiting the growth of
cancer cells expressing the IL–13
receptor. Most generally, the patent
application claims immunotoxins
consisting of anti-IL–13 antibodies
bound to toxins such as pseudomonas
exotoxin or diphtheria toxin, or a
cytotoxic fragment thereof, used in
combination with alkylating agents.
This combination appears to have
significant advantages over use of either
agent alone in the treatment of
malignant gliomas, head and neck
cancers, adenocarcinomas of the colon,
stomach of skin, and Hodgkin’s disease.

This invention relates to the discovery
that tristetraprolin (TTP) can promote
the poly(A)RNase (PARN) mediated
deadenylation of polyadenylated
substrates containing AU-rich elements
(AREs). As one aspect of the invention,
the inventors have developed a cell free
system that may be used for the
purposes of assessing the effects of the
various system components or their
derivatives (i.e. AREs, PARN, or TTP)
on the deadenylation process or the
effects of various test agents on the
deadenylation process. Aspects of this
work have been published as follows:

Family Members Can Promote the CellFree Deadenylation of AU-Rich
Element-Containing mRNAs by Poly(A)
Ribonuclease, MCB 23(11):3798–3812.
This technology is available for
licensing on an exclusive or a nonexclusive basis.
In addition to licensing, the
technology is available for further
development through collaborative

inventors.
Tristetraprolin (TTP) Knockout Mice

DHHS Reference No. B–015–1999/0—
Research Material.
Licensing Contact: Michelle A. Booden;
301/451–7337;
boodenm@mail.nih.gov.
National Institutes of Health
researchers have developed knockout
mice that do not express Tristetraprolin
(TTP). TTP is an AU-rich element (ARE)
binding protein and the prototype of a
family of CCCH zinc finger proteins.
AREs were identified as conserved
sequences found in the 3’ untranslated
region (3’ UTR) of a variety of
transiently expressed genes including
early respsonse genes, proto-oncogenes,
and other growth regulatory genes.
AREs function as instability sequences
that target ARE-containing transcripts
for rapid mRNA decay. TTP functions
by binding directly to the ARE sequence
contained in the TNF-alpha mRNA,
which destabilizes and mediates rapid
decay of the TNF-alpha mRNA. More
recent studies demonstrate TTP’s ability
to downregulate IL–2 gene expression.
TTP knockout mice appear normal at
birth but soon develop inflammatory
arthritis, dermatitis, cachexia,
autoimmunity, and myeloid

hyperplasia. Almost all aspects of these
phenotypes can be prevented with
repeated injections of antibodies to
TNF. Moreover, macrophages isolated
from these mice exhibit increased
production of TNF-alpha and increased
amounts of TNF-alpha mRNA.
This transgenic mouse model will be
valuable in advancing our
understanding of the mechanisms
controlling mRNA turnover in immune
homeostasis as well as autoimmune
diseases. This model will also permit
the development of screening assays to
elucidate the functions and binding
partners for other members of the CCCH
zinc finger family as well as compounds
capable of inhibiting aberrant TNFalpha and IL–2 biosynthesis. Lastly, this
model will advance understanding of
the pathogenetic role for IL–2 and/or
TNF in various autoimmune and
inflammatory diseases. The mice will be
made available on a non-exclusive basis
under a Biological Materials License
Agreement.

Inhibiting IL-13 Receptor-Expressing Cancer Cells With Anti-IL-13
Receptor Immunotoxin and Alkylating Agents
Raj Puri and Syed Husain (FDA); U.S. Provisional Application No.

Licensing Contact: Brenda Hefti; (301) 435-4632; heftib@mail.nih.gov.
The present invention relates to methods of inhibiting the growth
of cancer cells expressing the IL-13 receptor. Most generally, the
patent application claims immunotoxins consisting of anti-IL-13
antibodies bound to toxins such as pseudomonas exotoxin or diphtheria
toxin, or a cytotoxic fragment thereof, used in combination with
alkylating agents. This combination appears to have significant
advantages over use of either agent alone in the treatment of malignant
gliomas, head and neck cancers, adenocarcinomas of the colon, stomach
of skin, and Hodgkin's disease.

This invention relates to the discovery that tristetraprolin (TTP)
can promote the poly(A)RNase (PARN) mediated deadenylation of
polyadenylated substrates containing AU-rich elements (AREs). As one
aspect of the invention, the inventors have developed a cell free
system that may be used for the purposes of assessing the effects of
the various system components or their derivatives (i.e. AREs, PARN, or
TTP) on the deadenylation process or the effects of various test agents
on the deadenylation process. Aspects of this work have been published
as follows: Lai et al., 2003, Tristetraprolin and Its Family Members
Can Promote the Cell-Free Deadenylation of AU-Rich Element-Containing
mRNAs by Poly(A) Ribonuclease, MCB 23(11):3798-3812.

Tristetraprolin (TTP) Knockout Mice

National Institutes of Health researchers have developed knockout
mice that do not express Tristetraprolin (TTP). TTP is an AU-rich
element (ARE) binding protein and the prototype of a family of CCCH
zinc finger proteins. AREs were identified as conserved sequences found
in the 3' untranslated region (3' UTR) of a variety of transiently
expressed genes including early respsonse genes, proto-oncogenes, and
other growth regulatory genes. AREs function as instability sequences
that target ARE-containing transcripts for rapid mRNA decay. TTP
functions by binding directly to the ARE sequence contained in the TNF-
alpha mRNA, which destabilizes and mediates rapid decay of the TNF-
alpha mRNA. More recent studies demonstrate TTP's ability to
downregulate IL-2 gene expression.
TTP knockout mice appear normal at birth but soon develop
inflammatory arthritis, dermatitis, cachexia, autoimmunity, and myeloid
hyperplasia. Almost all aspects of these phenotypes can be prevented
with repeated injections of antibodies to TNF. Moreover, macrophages
isolated from these mice exhibit increased production of TNF-alpha and
increased amounts of TNF-alpha mRNA.
This transgenic mouse model will be valuable in advancing our
understanding of the mechanisms controlling mRNA turnover in immune
homeostasis as well as autoimmune diseases. This model will also permit
the development of screening assays to elucidate the functions and
binding partners for other members of the CCCH zinc finger family as
well as compounds capable of inhibiting aberrant TNF-alpha and IL-2
biosynthesis. Lastly, this model will advance understanding of the
pathogenetic role for IL-2 and/or TNF in various autoimmune and
inflammatory diseases. The mice will be made available on a non-
exclusive basis under a Biological Materials License Agreement.
