PURPOSE OF THIS RFA
The purpose of this initiative is to support basic and clinical
research on the role of cranberry (Vaccinium macrocarpon) in the
prevention and treatment of urinary tract infections (UTI), other
infections, and other conditions for which there is credible evidence
of efficacy. For clinical trials, preference will be given to those
that also test mechanistic hypotheses. This research may lead to
definitive Phase III trials to determine the efficacy of cranberry in
the prevention and/or treatment of UTI or other conditions. Products
of primary interest are (1) cranberry juice cocktail and (2)
encapsulated powders, and their matching placebos.
RESEARCH OBJECTIVES
Cranberry juice and to a lesser extent encapsulated powders have been
used to prevent or treat UTI. Preliminary evidence supports efficacy
but the research suffers from major limitations. Additional, but more
limited, research of cranberry because of its inhibition of bacterial
adhesion and antioxidant properties has been conducted for other
infectious diseases and other conditions. The appropriate product,
dose, duration of intervention, and mechanism(s) of action are unknown
or not clearly elucidated. Finally, the nature and quality of
previously studied cranberry products is not available in most of the
published literature. This limitation led NCCAM to award a contract
for the development, preparation, characterization, standardization,
and maintenance of a supply of research-grade cranberry products and
matching placebos for use in NIH-sponsored clinical trials on
cranberry. These products will be available and are required for use
by respondents to this RFA which seeks investigator-initiated basic and
clinical research applications.
Significance
UTIs are a serious health problem affecting millions of people each
year. Infections of the urinary tract are common - only respiratory
infections occur more often. Each year, UTIs account for about seven
million office visits and another one million emergency department
visits, resulting in about 100,000 hospitalizations. One woman in five
develops a UTI during her lifetime; UTIs in men are less common.
Nearly 20% of women who have a UTI will have another, and 30% of those
will have yet another.
Most infections arise from one type of bacteria, Escherichia coli,
which normally live in the colon. Usually, the most recent infection
stems from a strain or type of bacteria that is different from the
infection before it, indicating a separate infection. (Even when
several UTIs in a row are due to E. coli, slight differences in the
bacterial strains indicate distinct infections.) NIH-funded research
suggests that one factor behind recurrent UTIs may be the ability of
bacteria to attach to cells lining the urinary tract.
Cranberry Use for UTI
Traditionally UTIs are treated with antibacterial drugs, but these are
expensive, can have side effects, and may promote the emergence of
drug-resistant bacteria. Therefore, physicians suggest additional
steps that patients can take on their own to avoid infection, including
drinking cranberry juice
(http://www.niddk.nih.gov/health/urolog/pubs/utiadult/utiadult.htm).
Although cranberry juice is the form of cranberries most widely used,
other cranberry products include cranberry powder in hard or soft
gelatin capsules. Market share data reported for 1999 and 2001 rank
cranberry as number 10 and 9, respectively, among top-selling herbal
products in the U.S. in the mainstream retail market
Efficacy of Cranberry for UTI
The use of cranberry to prevent or treat UTI is common. The
accumulating evidence from small, non-controlled and controlled
clinical trials suggests that cranberry may relieve symptoms associated
with UTI and may reduce the need for antibiotics. The findings from the
preliminary research provide reasons to support the conduct of small-
scale, focused clinical studies.
In 1998 (updated 2001), the Cochrane Library conducted separate reviews
of cranberry for the prevention and treatment of UTI. Each review
used similar search strategies and selection criteria. These included
all randomized or quasi-randomized controlled trials. Trials of at
least one month and at least five days were included for prevention and
treatment, respectively. For prevention, four trials met the inclusion
criteria. For treatment, no trials meeting the inclusion criteria were
found; only a few uncontrolled trials were found. The Cochrane Library
concluded that there was no good quality or reliable evidence of the
effectiveness of cranberry juice or other cranberry products for the
prevention or treatment of UTI and that more research is needed.
Three crossover studies (not included in either review) investigated
the effect of cranberry on urine pH but did not attempt to assess
activity in UTI. Two of these three studies demonstrated a decrease in
pH whereas the third study did not demonstrate a decrease in pH.
Several other studies not included in the Cochrane reviews reported
apparently contradictory results. The first did not support the
efficacy of cranberry in UTI in children with neurogenic bladder. The
second was a study of adults with spinal cord injury that demonstrated
a reduction in biofilm load, but the importance of this effect for
frank UTI was not determined. A small study of urostomy patients also
found equivocal results.
Many of the clinical study reports available in the literature suffer
from major limitations, as acknowledged in the Cochrane Library
reviews. Many trials have not been controlled or randomized, and
randomization procedures have not always been described. Crossover
designs used in some studies may not be appropriate for studies of UTI.
Other limitations include no blinding or failed blinding, lack of
controlled diets or dietary assessment, use of convenience samples, and
small numbers of subjects. Sample sizes have ranged from as few as 10
to as many as 192. Trials have been faulted for the large number of
dropouts/withdrawals which may be indicative that cranberry juice is
not acceptable over the longer periods. Intention-to-treat analyses
were not often applied. Most studies have been conducted in older or
elderly patients. Very few have been conducted in younger patients,
with or without co-morbidities. Primary outcomes have differed from
study to study and have often included urinary pH, as well as rate of
bacteriuria, biofilm load, and urinary white and red blood cell counts,
rather than UTI. Finally, the published articles do not describe the
quality and character of the product.
Mechanism of Action for UTI
The mechanism of action of cranberry in treatment of UTI has not been
clearly elucidated, but several potential hypotheses have been
proposed.
High levels of benzoic acid have been detected in cranberry juice, and
until recently, it was suggested that the bacteriostatic effect of
cranberry juice was due to acidification of the urine. Several
studies, however, have cast doubt on this mechanism.
Current belief is that the prevention of UTI is achieved by inhibiting
adhesion of the infecting bacteria, E. coli, to uroepithelial cells.
Bacterial adherence to these cells is a critical step in the
development of infection. It is facilitated by fimbriae (proteinaceous
fibers on the bacterial cell well). Fimbriae produce adhesins which
attach to receptors on uroepithelial cells. It is hypothesized that
cranberry constituents act by preventing adhesion. Thus, the causative
bacteria are flushed, preventing their colonization of the urinary
tract. In addition, there has been a report of the potential of
cranberry juice to weaken attachment of E. coli to inert (nonliving)
surfaces for control of biofilm formation on urinary catheters.
Two components of cranberry juice have been shown to inhibit the
adherence of E. coli to uroepithelial cells in vitro. The first is
fructose which may not survive absorption and metabolism intact to
reach the urinary bladder. The second is a group of polymeric
proanthocyanidins; the chemical structures of three have been
elucidated. Fructose inhibits the adherence of type-1 fimbriated E.
coli and proanthocyanidins inhibit the adherence of P-fimbriated E.
coli to uroepithelial cells.
Cranberry for Other Infections and Conditions
While much of the focus on the benefits of cranberry has been on UTI,
cranberry could influence other conditions as well. Examples of other
areas of cranberry research follow. These are for illustration only
and are not meant to be exhaustive.
Burger et al. reason that because cranberry has been shown to inhibit
bacterial adhesion to uroepithelial cells, it may also be useful as
antiadhesion therapy of Helicobacter pylori infections. In a number of
small in vitro studies, the investigators demonstrated that a high-
molecular-weight constituent of cranberry inhibits sialyllactose-
specific adhesion of H. pylori to a human gastric cell line and mucus,
and to human erythrocytes.
Because of cranberry's purported antiadhesive properties, the effect of
cranberry on the coaggregation of oral bacteria was tested. A high-
molecular-weight nondialysable material was isolated from cranberry
juice. Although the molecular structure of this material and its
mechanism of action are not known, in vitro studies showed that
coaggregation of pairs of bacteria was inhibited and pilot in vivo
studies showed that coaggregation of a large number of different pairs
was reversed. A small pilot study of individuals using a standard
mouthwash which contained this high-molecular-weight constituent was
conducted. Results showed a reduction in colony forming units in
saliva.
Cranberry extracts may inhibit the oxidative modification of low-
density-lipoprotein (LDL) particles in a fashion similar to that of red
wine and Concord grape juice as demonstrated in an in vitro study. In
vivo studies to evaluate the potential of cranberry to improve LDL
antioxidant capacity have not been conducted.
Other areas of emerging preliminary data include the inhibition of
breast cancer cells in animals, as well as the inhibition of certain
strains of Haemophilus influenzae that is a common cause of ear and
respiratory infections in children.
Safety
Cranberry taken orally in food amounts appears safe, although ingesting
large amounts may result in diarrhea and other gastrointestinal
symptoms. Safety of amounts greater than that consumed in foods is
unknown. One study of cranberry tablets suggests caution for patients
at risk for nephrolithiasis until safety of cranberry is confirmed.
Currently, there is insufficient reliable information available to
assess the interaction of cranberry with dietary supplements,
medications, foods or laboratory tests.
Cranberry Product
The dose, duration of intervention, and product characteristics
necessary for efficacy in prevention or treatment of UTI are unknown.
While cranberry juice cocktail is the most studied product,
concentrates and encapsulated powders have also been used. Some
sources suggest six capsules of dried cranberry powder are equivalent
to two fluid ounces cranberry juice cocktail. The chemical composition
of the study agents, in general, has not been described in the
published literature, nor has the equivalence of the active
constituents or markers among cocktails, concentrates, and
capsules/tablets been described. Therefore, comparison among study
agents or trial results has not been possible.
The single-strength cranberry juice is highly acidic and astringent
which makes it unpalatable. Accordingly, the juice drink, i.e.,
cranberry juice cocktail, is a mixture of single-strength cranberry
juice, sweetener, water, and vitamin C. Cocktails are sweetened with
fructose or artificially sweetened. The percent of concentrate used in
cocktails has ranged from about 25% to 80%, although cocktail with 33%
pure juice is common.
Cranberries contain about 88% water. Among the other organic
constituents are flavonoids, anthocyanins, catechin, triterpenoids,
beta-hydroxybutyric acid, citric, malic, glucuronic, quinic and benzoic
acids, ellagic acid, and vitamin C. Quinic acid and the ratio of
quinic acid to malic acid are reasonably constant and are used to
calculate percentage of cranberry juice content in juice drinks and to
assess cranberry juice authenticity. Although anthocyanins change and
degrade with processing and storage, the anthocyanin profile is unique
to cranberry, and its qualitative pattern is characteristic.
Doses of the cocktails used in studies have ranged from 160 to 750 ml a
day, usually in divided doses at meals. Intervention duration has also
ranged from 5 days to 6 months (longer trials for prevention). The
rationale behind the amount and concentration of cranberry juice given
to participants and the duration of intervention is usually not
indicated.
Related NIH-Supported Cranberry Projects
The NCCAM awarded a contract to support the preparation,
characterization, standardization, and maintenance of a supply of
research-grade cranberry products and matching placebos with
concomitant quality control and quality assurance. See the Request for
Proposals for more detail: http://nccam.nih.gov/research/
announcements/rfp/sow.pdf. These products will be used in
NIH-supported basic and clinical research, which is
responsive to this RFA, on the role of cranberry (Vaccinium
macrocarpon) in the prevention and treatment of urinary tract
infections (UTI), other infections, and other conditions for which
there is credible evidence of efficacy. Products developed by the
contractor will be (1) cranberry juice cocktail and (2) encapsulated
powders, and their matching placebos.
Potential Research Directions
Although the objectives of this RFA are listed in the next section
(Objectives of This Research Program), the published literature
suggests that research directions might include, but not be limited to:
o Study the effect of cranberry in prevention of UTI and as adjunct to
antibiotics in the treatment of UTI;
o Demonstrate whether cranberry reduces symptomatic UTI (primary
endpoint being UTI; secondary endpoints being bacteriuria or pyuria);
o When justified, conduct randomized controlled trials of longer
durations in a variety of patients with recurrent UTI;
o Determine the optimum amount of cranberry (dose-response), timing of
ingestion, peak times to effect (temporal effect), variations in
response;
o Assess adherence to study dosage and frequency requirements and
participant retention;
o Assess the contribution of cranberry juice to increased fluid intake
(concentrate vs. juice vs. other beverage) and the effect on UTI;
o Collect data systematically on adverse effects;
o Assess interactions with medications (such as antibiotics and H2
blockers), dietary supplements, foods, and laboratory tests;
o Evaluate relationship of cranberry/cranberry constituents to
bacterial adherence;
o Evaluate relationship of cranberry/cranberry constituents and
bacterial adherence to urinary pH;
o Study the absorption and distribution of marker compounds and key
constituents of cranberry, such as the proanthocyanidins, to determine
whether they achieve tissue and body fluid concentrations needed to
inhibit bacterial adherence and other relevant biological endpoints;
o Investigate the antiadhesive property of cranberry/cranberry
constituents on different strains of bacteria, as well as on various
cellular substrates;
o Confirm/identify active agent(s) and/or other biochemical properties;
o Assess the equivalence of different cranberry products.
Objectives of This Research Program
Specifically, the objectives of this RFA are to:
o Conduct laboratory studies to identify and test mechanisms that could
explain the biological effects of cranberry/cranberry constituents;
o Study the basic mechanism(s) by which the constituents of cranberry
block supra- or subgingival biofilm formation associated with dental
caries, periodontal diseases or oral mucosal infections.
o Determine pharmacodynamics and pharmacokinetics of
cranberry/cranberry constituents in animal models and/or human
subjects; and
o Conduct Phase I/II clinical studies to assess dose range effects,
pharmacology, feasibility, safety, and biological efficacy of a
cranberry products to justify subsequent, more definitive trials of
their safety and efficacy. (A Phase II study may be of modest size,
provided it explores a range of dosages and is adequately powered to
detect a meaningful difference between groups or validate surrogate
markers of disease or clinical endpoints.) (Phase III studies will be
considered not responsive to this RFA).
MECHANISM OF SUPPORT
This RFA will use NIH R01 and R21 award mechanisms. 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 December 1, 2003. Applications that are not
funded in the competition described in this RFA may be resubmitted as
NEW investigator-initiated applications using the standard receipt
dates for NEW applications described in the instruction to the PHS 398
application.
This RFA uses just-in-time concepts. It also uses the modular as well
as the non-modular budgeting formats (see
http://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 NIH intends to commit approximately $2.6 million in FY04 to fund
five to 13 new and/or competitive continuation grants in response to
this RFA.
An R21 applicant may request a project period of up to two years with a
combined budget for direct costs of up to $275,000 for the two-year
period.
An R01 applicant may request a project period of up to four years and a
budget of no more than $500,000 direct costs per year.
Because the nature and scope of the proposed research will vary from
application to application, it is anticipated that the size and
duration of each award will also vary. Although the financial plans of
the NCCAM, NIDCR, NIDDK, and ODS 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.
Applicant institutions are strongly encouraged to discuss proposed
projects with relevant NIH staff listed under INQUIRIES prior to
submission.
ELIGIBLE INSTITUTIONS
You may submit (an) application(s) if your institution has any of the
following characteristics:
o For-profit or non-profit organizations
o Public or private institutions, such as universities, colleges,
hospitals, and laboratories
o Units of State and local governments
o Eligible agencies of the Federal government
o Domestic or foreign
o Faith-based or community-based organizations
INDIVIDUALS ELIGIBLE TO BECOME PRINCIPAL INVESTIGATORS
Individuals with the skills, knowledge, and resources necessary to
carry out the proposed research are invited to work with their
institution to develop an application for support. Individuals from
underrepresented racial and ethnic groups as well as individuals with
disabilities are always encouraged to apply for NIH programs.
SPECIAL REQUIREMENTS
This RFA seeks investigator-initiated basic and clinical research
applications. There is no common protocol. However, special
requirements are listed below.
o All grantees responsive to this RFA will be required to use the
research-grade cranberry product(s) developed by a contractor.
Therefore, the grant applicant is not responsible for the cost of the
cranberry product(s).
Products developed by the contractor will be (1) cranberry juice
cocktail and (2) encapsulated powders, and their matching placebos.
The contractor will prepare, characterize, standardize, and maintain a
supply of research-grade cranberry products and matching placebos with
concomitant quality control and quality assurance. It will provide
(e.g., label, package, store, inventory, and distribute) the
standardized cranberry products to the NIH-sponsored grantees
responsive to this RFA. The contractor will also provide the grantees
with information about the proper dispensing, handling, and
administration of the study agents. See the Request for Proposals for
more detail: http://nccam.nih.gov/research/announcements/rfp/sow.pdf.
The contractor has been asked to provide cranberry products in batches
to the grantees. A one-year supply of cranberry juice cocktail will
be delivered annually on or about June 1, 2004-2007. A two-year supply
of the supplement will be delivered on or about June 1, 2004 and 2006.
For application purposes, grant applicants may plan their own study
timelines; however, they should indicate their willingness to be
flexible if their study agents are not available at the time they had
originally planned. The actual delivery dates and type and dose of
products will be finalized in collaboration with the grantees, the
contractor, and the NIH.
o For only those applicants who intend to study single constituents
isolated from the whole cranberry: Studies that aim solely to
identify/test a single chemical constituent of cranberry will not be
supported by NCCAM under this RFA. Studies in which single
constituents are compared with the complex cranberry product are,
however, appropriate. For application purposes, these applicants will
be responsible for the chemical isolation, characterization, quality
and supply of the product for their own project. After grant award,
the NIH will negotiate with the contractor for the research-grade whole
cranberry product to develop and provide the isolated constituent. If
successful in this negotiation, grant awards will be revised.
o All grantees are responsible for their own travel costs in about
January 2004 (or earlier)to meet once in the Washington DC metropolitan
area with the contractor providing the research-grade cranberry
products and the NIH to determine study agent needs (agent type,
dosing, quantities, labeling, packaging and delivery) and
production/delivery schedules. In addition, the contractor will
conduct monthly conference calls (from about December 2003 through
September 2004) with the grantees and the NIH.
o Grantees conducting clinical studies are expected to file
applications for Investigational New Drugs (IND) with the Food and Drug
Administration (FDA) after award (tentatively prior to April 2004).
However, contact with the FDA regarding FDA requirements and need for
an IND would be appropriate prior to submission of the grant
application to the NIH.
The contractor providing the research-grade cranberry products will be
responsible for assisting the grantees by completing sections of the
IND application. The contractor will provide the following sections of
the IND applications (referencing the Drug Master File may be
appropriate) to the grantees by January 1, 2004: (1) Investigator's
Brochures for the cranberry products. (2) Chemistry, manufacturing,
and control information on the cranberry products. (3) Pharmacology
and toxicology data, if available. (4) Previous human experience,
including a list of the countries where the products are in clinical
testing or have been approved or marketed, if appropriate. The grantee
will be responsible for all other sections.
[NOTE: Under current regulations, any use in the United States of a
drug product (e.g., well-characterized, therapeutic, biotechnology-
derived products) not previously authorized for marketing in the United
States first requires submission of an IND to the FDA. NIH grantees
are required in the PHS 398 application to name the test article and
state whether the 30-day interval between submission of applicant
certification to the FDA and its response has elapsed or has been
waived and/or whether use of the test article has been withheld or
restricted by the FDA. However, for purposes of this RFA, grant
applicants are not expected to submit IND applications until after the
grant award.]
o Grantees conducting clinical trials must enter into a Clinical Trial
Agreement. Further information on NCCAM requirements for clinical
trials are posted on the NCCAM website
(http://nccam.nih.gov/research/policies/index.htm). Clinical trials
will be conducted under Good Clinical Practice (GCP) conditions as
defined in the FDA document "E6 Good Clinical Practice: Consolidated
Guidance" (http://www.fda.gov/cder/guidance/959fnl.pdf).
o Applications for studies comparing cranberry product to a non-
cranberry product will not be considered responsive to this RFA and
will be returned to the applicant without further consideration.
o Phase III studies will be considered not responsive to this RFA and
will be returned to the applicant without further consideration.
o Applications requesting greater than $500,000 direct costs in any
year will be considered not responsive to this RFA and will be returned
to the applicant without further consideration.

applicant without review.
Although there is no immediate acknowledgement of the receipt of an
application, applicants are generally notified of the review and
funding assignment within eight weeks.
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. However, when a previously unfunded application,
originally submitted as an investigator-initiated application, is to be
submitted in response to an RFA, it is to be prepared as a NEW
application. That is the application for the RFA must not include an
Introduction describing the changes and improvements made, and the text
must not be marked to indicate the changes. While the investigator may
still benefit from the previous review, the RFA application is not to
state explicitly how.
PEER REVIEW PROCESS
Upon receipt, applications will be reviewed for completeness and
responsiveness by the NCCAM.
Incomplete applications will be returned to the applicant without
further consideration.
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 NCCAM 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 Advisory Council for
Complementary and Alternative Medicine, NCCAM.
REVIEW CRITERIA
The R21 exploratory/developmental grant is a mechanism for exploring
the feasibility, as well as the development, of research projects and
for generation of preliminary data. The R21 mechanism is specifically
intended to support innovative ideas where preliminary data as evidence
of feasibility are sparse or do not exist. These grants are not
intended for large-scale undertakings or to support or
supplement ongoing research. Rather, R21 grants are intended to serve
as a basis for planning and strengthening future research project grant
applications(R01). It is important to note that, while originality
(innovation) of approach and potential significance of the proposed
research are major considerations in evaluation of R21 grant
applications, the applicant is responsible for presenting the
background literature that provides some basis for the approach and for
developing a rigorous research plan. Because the research plan is
limited to 15 pages, an exploratory/developmental grant application
need not have as much background material or preliminary information as
one might normally expect in an R01 application. Accordingly,
reviewers will focus their evaluation on the conceptual framework, the
level of innovation, and the potential to significantly advance our
knowledge or understanding. Appropriate justification for the proposed
work can be provided through literature citations, data from other
sources, or from investigator-generated data. Preliminary data are not
required but should be presented if available.
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,
an investigator may propose to carry out important work that by its
nature is not innovative but is essential to move a field forward.
SIGNIFICANCE: Does this study address an important problem? If the aims
of the application are achieved, how will scientific knowledge be
advanced? What will be the effect of these studies on the concepts or
methods that drive this field?
APPROACH: Are the conceptual framework, design, methods, and analyses
adequately developed, well-integrated, and appropriate to the aims of
the project? Does the applicant acknowledge potential problem areas and
consider alternative tactics?
INNOVATION: Does the project employ novel concepts, approaches or
methods? Are the aims original and innovative? Does the project
challenge existing paradigms or develop new methodologies or
technologies?
INVESTIGATOR: Is the investigator appropriately trained and well suited
to carry out this work? Is the work proposed appropriate to the
experience level of the principal investigator and other researchers
(if any)?
ENVIRONMENT: Does the scientific environment in which the 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?
PROTECTION OF HUMAN SUBJECTS FROM RESEARCH RISK: The involvement of
human subjects and protections from research risk relating to their
participation in the proposed research will be assessed. (See criteria
included in the section on Federal Citations, below).
INCLUSION OF WOMEN, MINORITIES AND CHILDREN IN RESEARCH: 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 in the
sections on Federal Citations, below).
CARE AND USE OF VERTEBRATE ANIMALS IN RESEARCH: If vertebrate animals
are to be used in the project, the five items described under Section f
of the PHS 398 research grant application instructions (rev. 5/2001)
will be assessed.
ADDITIONAL CONSIDERATIONS
o BUDGET: The reasonableness of the proposed budget and the requested
period of support in relation to the proposed research.

Application Receipt Date: May 20, 2003
Peer Review Date: September-October, 2003
Council Review: November, 2003
Earliest Anticipated Start Date: December 1, 2003
AWARD CRITERIA
Award criteria that will be used to make award decisions include:
o Scientific merit (as determined by peer review)
o Availability of funds
o Programmatic priorities.
REQUIRED FEDERAL CITATIONS
HUMAN SUBJECTS PROTECTION: Federal regulations (45CFR46) require that
applications and proposals involving human subjects must be evaluated
with reference to the risks to the subjects, the adequacy of protection
against these risks, the potential benefits of the research to the
subjects and others, and the importance of the knowledge gained or to
be gained.
MONITORING PLAN AND DATA SAFETY AND MONITORING BOARD: Research
components involving Phase I and II clinical trials must include
provisions for assessment of patient eligibility and status, rigorous
data management, quality assurance, and auditing procedures. In
addition, it is NIH policy that all clinical trials require data and
safety monitoring, with the method and degree of monitoring being
commensurate with the risks (NIH Policy for Data Safety and Monitoring,
NIH Guide for Grants and Contracts, June 12, 1998:
http://grants.nih.gov/grants/guide/notice-files/not98-084.html).
INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH: It is the policy
of the NIH that women and members of minority groups and their sub-
populations must be included in all NIH-supported clinical research
projects unless a clear and compelling justification is provided
indicating that inclusion is inappropriate with respect to the health of
the subjects or the purpose of the research. This policy results from
the NIH Revitalization Act of 1993 (Section 492B of Public Law 103-43).
All investigators proposing clinical research should read the "NIH
Guidelines for Inclusion of Women and Minorities as Subjects in
Clinical Research - Amended, October, 2001," published in the NIH Guide
for Grants and Contracts on October 9, 2001
(http://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-001.html); a
complete copy of the updated Guidelines are available at http://grants.
nih.gov/grants/funding/women_min/guidelines_amended_10_2001.htm.
The amended policy incorporates: the use of an NIH definition
of clinical research; updated racial and ethnic categories in
compliance with the new OMB standards; clarification of language
governing NIH-defined Phase III clinical trials consistent with the new
PHS Form 398; and updated roles and responsibilities of NIH staff and
the extramural community. The policy continues to require for all NIH-
defined Phase III clinical trials that: a) all applications or
proposals and/or protocols must provide a description of plans to
conduct analyses, as appropriate, to address differences by sex/gender
and/or racial/ethnic groups, including subgroups if applicable; and b)
investigators must report annual accrual and progress in conducting
analyses, as appropriate, by sex/gender and/or racial/ethnic group
differences.
INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN
SUBJECTS: The NIH maintains a policy that children (i.e., individuals
under the age of 21) must be included in all human subjects research,
conducted or supported by the NIH, unless there are scientific and
ethical reasons not to include them. This policy applies to all initial
(Type 1) applications submitted for receipt dates after October 1, 1998.
All investigators proposing research involving human subjects should
read the "NIH Policy and Guidelines" on the inclusion of children as
participants in research involving human subjects that is available at
http://grants.nih.gov/grants/funding/children/children.htm.
REQUIRED EDUCATION ON THE PROTECTION OF HUMAN SUBJECT PARTICIPANTS: NIH
policy requires education on the protection of human subject
participants for all investigators submitting NIH proposals for research
involving human subjects. You will find this policy announcement in the
NIH Guide for Grants and Contracts Announcement, dated June 5, 2000, at
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-039.html.
HUMAN EMBRYONIC STEM CELLS (hESC): Criteria for federal funding of
research on hESCs can be found at
http://grants.nih.gov/grants/stem_cells.htm and at
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-005.html.
Only research using hESC lines that are registered in the NIH Human
Embryonic Stem Cell Registry will be eligible for Federal funding (see
http://escr.nih.gov). It is the responsibility of the applicant to
provide the official NIH identifier(s)for the hESC line(s)to be used in
the proposed research. Applications that do not provide this
information will be returned without review.
PUBLIC ACCESS TO RESEARCH DATA THROUGH THE FREEDOM OF INFORMATION ACT:
The Office of Management and Budget (OMB) Circular A-110 has been
revised to provide public access to research data through the Freedom of
Information Act (FOIA) under some circumstances. Data that are (1)
first produced in a project that is supported in whole or in part with
Federal funds and (2) cited publicly and officially by a Federal agency
in support of an action that has the force and effect of law (i.e., a
regulation) may be accessed through FOIA. It is important for
applicants to understand the basic scope of this amendment. NIH has
provided guidance at
http://grants.nih.gov/grants/policy/a110/a110_guidance_dec1999.htm.
Applicants may wish to place data collected under this PA in a public
archive, which can provide protections for the data and manage the
distribution for an indefinite period of time. If so, the application
should include a description of the archiving plan in the study design
and include information about this in the budget justification section
of the application. In addition, applicants should think about how to
structure informed consent statements and other human subjects
procedures given the potential for wider use of data collected under
this award.
URLs IN NIH GRANT APPLICATIONS OR APPENDICES: All applications and
proposals for NIH funding must be self-contained within specified page
limitations. Unless otherwise specified in an NIH solicitation, Internet
addresses (URLs) should not be used to provide information necessary to
the review because reviewers are under no obligation to view the
Internet sites. Furthermore, we caution reviewers that their anonymity
may be compromised when they directly access an Internet site.
HEALTHY PEOPLE 2010: The Public Health Service (PHS) is committed to
achieving the health promotion and disease prevention objectives of
"Healthy People 2010," a PHS-led national activity for setting priority
areas. This RFA is related to one or more of the priority areas.
Potential applicants may obtain a copy of "Healthy People 2010" at
http://www.health.gov/healthypeople.
AUTHORITY AND REGULATIONS: This program is described in the Catalog of
Federal Domestic Assistance at http://www.cfda.gov/ and is not subject
to the intergovernmental review requirements of Executive Order 12372
or Health Systems Agency review. Awards are made under the
authorization of Sections 301 and 405 of the Public Health Service Act
as amended (42 USC 241 and 284) and under Federal Regulations 42 CFR 52
and 45 CFR Parts 74 and 92. All awards are subject to the terms and
conditions, cost principles, and other considerations described in the
NIH Grants Policy Statement. The NIH Grants Policy Statement can be
found at http://grants.nih.gov/grants/policy/policy.htm.
The ODS was mandated by Congress in 1994 and established with the
Office of the Director, NIH. The Dietary Supplement Health and
Education Act (SHEA) [Public Law 103-417, Section 3.a] amended the
Federal Food, Drug, and Cosmetic Act "to establish standards with
respect to dietary supplements." This law authorized the establishment
of the ODS.
The PHS strongly encourages all grant recipients to provide a smoke-
free workplace and discourage the use of all tobacco products. In
addition, Public Law 103-227, the Pro-Children Act of 1994, prohibits
smoking in certain facilities (or in some cases, any portion of a
facility) in which regular or routine education, library, day care,
health care, or early childhood development services are provided to
children. This is consistent with the PHS mission to protect and
advance the physical and mental health of the American people.
