PURPOSE
The initiative will encourage applications focused on 1) validation of
surrogate biomarkers, which can be modulated by agents which may prevent
Estrogen Receptor (ER) negative breast cancer in animal models of non-
hormonally responsive mammary cancer. The experimental protocols in animals
should parallel potential clinical chemoprevention protocols for breast cancer
in humans, 2) identification of potential targets found both in hormonally
non-responsive animal models of breast cancer and in ER negative breast cancer
in humans and 3) determination of the efficacy of potential chemopreventive
agents. Modulatable surrogate biomarkers are broadly defined and might
include gene or protein expression, specific DNA mutations or chromosomal
alterations or characteristics associated with imaging (e.g. breast density,
nuclear morphometry, etc.) which can be quantitatively altered by an effective
chemopreventive agent. Modulatable surrogate biomarkers could be examined in
lesions (preinvasive lesions, invasive lesions), in at risk epithelium or in
serum. One should be able to demonstrate a strong correlation between
alteration of the biomarker and the effects of the chemopreventive agent on
tumor incidence and multiplicity in the animal model.
RESEARCH OBJECTIVES
Background
Preclinical studies using animal models have been critically important for
identifying a number of chemical agents which are now being applied in the
prevention of cancer (e.g., tamoxifen , raloxifene, retinoids, COX-2
inhibitors). Animal models aimed at developing new, specific and potentially
potent agents for prevention of ER negative breast cancer as well as
potentially offering modulatable biomarkers should accelerate and drive
forward the clinical research on ER negative breast cancer. These
developments should help to diminish the risk of ER negative breast cancer
and, in conjunction with agents which are effective against ER positive breast
cancer (tamoxifen, raloxifene, aromatase inhibitors) , offer the possibility
of regimens which will profoundly decrease the overall risk of breast cancer.
The American Cancer Society estimates that in this year 193,000 new cases of
breast cancer will be diagnosed and that roughly 40,000 women will die of this
disease. It is estimated that roughly 30% of breast cancers are ER negative
and that they represent 12-15,000 of the breast cancer related deaths each
year.
Short term pilot (Phase II) clinical studies in women at risk of developing ER
negative breast cancer represent an efficient way of demonstrating potential
efficacy of preventive agents. These studies depend heavily on the development
of potential agents and cancer-related surrogate endpoints employing animal
models. Such endpoints might include: levels of expression of specific genes
or proteins, incidence or levels of specific genetic alterations (LOH,
microsatellite alterations, FISH, mutations in suppressor/oncogenes, base
methylation in certain genes), and or parameters related to image analysis,
(e.g., nuclear morphometry , breast density, etc.). Such endpoints could be
determined in lesions, in epithelial cells at high risk of developing cancer
or in serum. These surrogate markers can be validated in animal studies where
experiments can be followed till the production of invasive tumors. Surrogate
endpoints that have already undergone some studies in animal models for breast
cancer include expression of various genes, proliferation, apoptosis, and
nuclear imaging. The incorporation of newer imaging technology into small
animal cancer prevention assays to validate their future use in clinical
trials protocols is also encouraged. However it is clear that a larger effort
is needed to validate surrogate endpoint biomarkers in preclinical models
employing intermediate endpoints similar to those proposed clinically for
women at high risk of ER negative tumors. Once validated in animal models with
a cancer endpoint, these biomarkers could then be rapidly translated into the
clinical trials effort. In developing these endpoint biomarkers, the use of
classes of agents which appear to be promising for ER negative breast cancer
(e.g. COX-2 inhibitors, EGFr inhibitors, RXR agonists , farnesyltransferase
inhibitors, etc.) might be prime candidates. Biomarkers developed for these
drugs could be immediately translated to clinical trials. In contrast markers
developed for totally new agents will require significant toxicologic and
pharmacologic testing of those new agents prior to their use in clinical
trials.
Further studies with several potential classes of agents warrant further
evaluation in relevant preclinical animal models before they can be nominated
for preventive interventions in the population of women at risk for ER
negative disease. For example, members of the non-steroidal anti-inflammatory
drug family (NSAIDs) have shown some efficacy in hormonally responsive models
of breast cancer and their primary target COX-2 is expressed in ER negative
tumors as well. Therefore, further investigations of this class of agents in
ER negative models appears appropriate. Based on preclinical animal studies
and limited human studies, other potential agents to consider, include
inhibitors of Neu and EGFr, rexenoids, farnesyl transferase inhibitors , etc.
While these are examples, additional agents based on specific targeting to ER
negative tumors are encouraged for testing in these applications. One might
hope that additional targets might be defined by examining genes or proteins
whose expression is altered in ER negative breast cancer. Thus EGFr and Neu
have been identified as potential targets. However, the continued cataloging
of gene and protein expression changes by RNA or proteomic approaches is
likely to result in many additional targets. Combination prevention trials
targeting specific biochemical pathways may also have great potential for
leading to more effective preventive strategies based on multiple mechanistic
approaches. Thus the combination of an antiestrogen/estrogen plus a rexenoid
appears to have synergistic effects in ER positive breast cancer models in
animals.
Objectives and Scope:
The development of animal model protocols that can facilitate the discovery
and development of agents to prevent or diminish the risk of ER negative
breast cancer in women represents an extraordinary opportunity to reduce
breast cancer incidence, morbidity, and mortality. The purpose of this
initiative is to invite investigator-initiated grant applications developing
and evaluating chemopreventive strategies preclinically which could be rapidly
translated to clinical studies and are applicable to women at high risk for
development of ER negative breast cancer. The range of activities supported
by this RFA would include preclinical studies to: 1) develop modulatable
endpoint biomarkers in animal models of hormonally non responsive breast
cancer employing effective preventive agents. Such biomarkers might include:
gene or protein expression, or specific molecular changes, DNA mutations,
image analysis etc. in specific preclinical models in which relevant cancer
incidence and multiplicity are decreased by known effective agents.
Interventions and determinations of endpoints that parallel potential clinical
protocols are of particular use. Thus clinical protocols are likely to
examine preinvasive lesions, at risk epithelia or sera in addition to more
advanced lesions for modulation of potential endpoints. However a portion of
any protocol would be to carry animals to an invasive tumor endpoint to
determine the correlation of marker modulation and the final tumor endpoint.
2) test and prioritize agents using preclinical animal models for ER negative
breast cancer. It would be expected that >40% of the animals would develop
hormonally non responsive mammary tumors in any model that is proposed. In
addition the model should develop preinvasive and invasive lesions that are
histologically similar to that observed in human breast cancer. The purpose
of this RFA is not primarily to support development of totally new animal
models for ER negative breast cancer. However, a grant which includes as a
component limited alteration or optimization or prevention testing in a
previously developed model is not precluded. If one employs a transgenic
animal model one must determine whether a given chemopreventive agent affects
expression of the promoter. 3) Further characterize by genomic, proteomic or
imaging techniques changes associated with hormonally non responsive breast
cancer in multiple animal models as well as correlating with those seen in
lesions or serum of humans with ER negative breast cancer or individuals at
high risk of developing, ER negative breast cancer. In order to facilitate
these comparative studies NCI will supply grantees funded via this RFA with a
limited number of animal tumors, normal tissue and serum samples from 3
different hormonally non responsive tumor models. The specific models may be
from rats or mice and will depend on availability. NCI will not supply
rodents for the primary chemopreventive studies.
Applicants are especially encouraged to apply chemopreventive agents directed
against certain of the recently identified molecular targets found in ER
negative breast cancer in humans (e.g. Neu, EGFr, COX-2) . Although it is
anticipated that any model would have been characterized for the presence of
histopathologic lesions it would be useful to do some early characterization
of any models for gene expression patterns and expression of targets that are
similar to that observed in humans. Approaches comparing any animal results
to known results in humans. For example, the published published results of
Perou, et al (Nature 406, 747-752 or results from the CGAP web site
(http://cgap.nci.nih.gov/) etc., can be employed. Based on these initial
characterizations the applicant should identify potential markers, e.g., genes
or gene products which are over expressed or under expressed in hormonally non
responsive mammary lesions in their model.
The investigators funded under this RFA will be encouraged to collaborate with
scientists involved in the Mouse Models for Human Cancer Consortia (MMHCC) and
take advantage of animal models developed in the MMHCC. Transgenic animal
models for mammary cancer are already under development and might be used with
the application of drug development. Similarly newly developed imaging
techniques that as are being evaluated as part of the MMHCC activities could
be incorporated.
The total project period for applications submitted in response to the present
RFA may not exceed 5 years. Because the nature and scope of the research
proposed in response to this RFA may vary, it is anticipated that the duration
and sizes of awards will vary also. Therefore applications will be accepted
for R01, R21/R33, and competitive supplements to existing awards in this area.
MECHANISM OF SUPPORT
This RFA will use the National Institutes of Health (NIH) research project
grant (R01) award mechanism. As an applicant, you will be solely responsible
for planning, directing, and executing the proposed project. This RFA is a
one-time solicitation. Future unsolicited, competing-continuation
applications based on this project will compete with all investigator-
initiated applications and will be reviewed according to the customary peer
review procedures. The anticipated award date is April 2003.
This RFA uses just-in-time concepts. It also uses the modular and non-modular
budgeting formats. (see
https://grants.nih.gov/grants/funding/modular/modular.htm). Specifically, if
you are submitting an application with direct costs in each year of $250,000
or less, use the modular format. Otherwise, follow the instructions for non-
modular research grant applications.
FUNDS AVAILABLE
The NCI intends to commit approximately $3.0 million in FY 2003 to fund 7 to
10 new and/or competitive continuation grants in response to this RFA. An
applicant may request a project period of up to 5 years and a budget for
direct costs of up to $300,000 per year. Facility and Administrative costs on
consortium arrangements are not included in direct cost requests greater than
$250,000. Because the nature and scope of the research proposed may vary, it
is anticipated that the size of each award will also vary. Although the
financial plans of the NCI provide support for this program, awards pursuant
to this RFA are contingent upon the availability of funds and the receipt of a
sufficient number of meritorious applications. At this time, it is not known
if competing renewal applications will be accepted and/or if this RFA will be
reissued.

APPLICATIONS HAND-DELIVERED BY INDIVIDUALS TO THE NATIONAL CANCER INSTITUTE
WILL NO LONGER BE ACCEPTED. This policy does not apply to courier deliveries
(i.e. FEDEX, UPS, DHL, etc.) (https://grants.nih.gov/grants/guide/notice-
files/NOT-CA-02-002.html) This change in practice is effective immediately.
This policy is similar to and consistent with the policy for applications
addressed to Centers for Scientific Review as published in the NIH Guide
Notice https://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-012.html.
APPLICATION PROCESSING: Applications must be received by the application
receipt date listed in the heading of this RFA. If an application is received
after that date, it will be returned to the applicant without review.
The Center for Scientific Review (CSR) will not accept any application in
response to this RFA that is essentially the same as one currently pending
initial review, unless the applicant withdraws the pending application. The
CSR will not accept any application that is essentially the same as one
already reviewed. This does not preclude the submission of substantial
revisions of applications already reviewed, but such applications must include
an Introduction addressing the previous critique.
PEER REVIEW PROCESS
Upon receipt, applications will be reviewed for completeness by the CSR and
for responsiveness by the NCI program staff.
Incomplete applications will be returned to the applicant without further
consideration. And, if the application is not responsive to the RFA, CSR
staff may contact the applicant to determine whether to return the application
to the applicant or submit it for review in competition with unsolicited
applications at the next appropriate NIH review cycle.
Applications that are complete and responsive to the RFA will be evaluated for
scientific and technical merit by an appropriate peer review group convened by
the Division of Extramural Affairs (DEA) at NCI in accordance with the review
criteria stated below. As part of the initial merit review, all applications
will:
o Receive a written critique
o Undergo a process in which only those applications deemed to have the
highest scientific merit, generally the top half of the applications under
review, will be discussed and assigned a priority score
o Receive a second level review by the National Cancer Advisory Board.
REVIEW CRITERIA
The goals of NIH-supported research are to advance our understanding of
biological systems, improve the control of disease, and enhance health. In
the written comments, reviewers will be asked to discuss the following aspects
of your application in order to judge the likelihood that the proposed
research will have a substantial impact on the pursuit of these goals:
o Significance
o Approach
o Innovation
o Investigator
o Environment
The scientific review group will address and consider each of these criteria
in assigning your application"s overall score, weighting them as appropriate
for each application. Your application does not need to be strong in all
categories to be judged likely to have major scientific impact and thus
deserve a high priority score. For example, you may propose to carry out
important work that by its nature is not innovative but is essential to move a
field forward.
(1) SIGNIFICANCE: Does your study address an important problem? If the aims
of your application are achieved, how do they advance scientific knowledge?
What will be the effect of these studies on the concepts or methods that drive
this field? Does your study address the development of agents and or
surrogate biomarkers applicable to estrogen receptor negative breast cancer?
Does your study include examination of tissues e.g. at risk epithelia,
preinvasive lesions, sera which are most likely to be obtained in clinical
cancer prevention studies? Do you propose the use of at least some agents
with known efficacy in the proposed or similar models? It will be difficult
to optimize markers with minimally effective agents.
(2) APPROACH: Are the conceptual framework, design, methods, and analyses
adequately developed, well integrated, and appropriate to the aims of the
project? Do you acknowledge potential problem areas and consider alternative
tactics? Are the approaches employed directly applicable to cancer
chemoprevention trials? Are any technical approaches directly applicable to
clinical cancer chemoprevention trials?
(3) INNOVATION: Does your project employ novel concepts, approaches or
methods? Are the aims original and innovative? Does your project challenge
existing paradigms or develop new methodologies or technologies?
(4) INVESTIGATOR: Are you appropriately trained and well suited to carry out
this work? Is the work proposed appropriate to your experience level as the
principal investigator and to that of other researchers (if any)?
(5) ENVIRONMENT: Does the scientific environment in which your work will be
done contribute to the probability of success? Do the proposed experiments
take advantage of unique features of the scientific environment or employ
useful collaborative arrangements? Is there evidence of institutional
support?
ADDITIONAL REVIEW CRITERIA: In addition to the above criteria, your
application will also be reviewed with respect to the following:
PROTECTIONS: The adequacy of the proposed protection for humans, animals, or
the environment, to the extent they may be adversely affected by the project
proposed in the application.
INCLUSION: The adequacy of plans to include subjects from both genders, all
racial and ethnic groups (and subgroups), and children as appropriate for the
scientific goals of the research. Plans for the recruitment and retention of
subjects will also be evaluated. (See Inclusion Criteria included in the
section on Federal Citations, below)
DATA SHARING: The adequacy of the proposed plan to share data.
BUDGET: The reasonableness of the proposed budget and the requested period of
support in relation to the proposed research.
