ORAL MUCOSAL INNATE IMMUNE FACTORS IN THE INHIBITION OF HIV AND OPPORTUNISTIC INFECTIONS Release Date: September 13, 2002 RFA: DE-03-002 National Institute of Dental and Craniofacial Research (NIDCR) (http://www.nidcr.nih.gov) LETTER OF INTENT RECEIPT DATE: November 13, 2002 APPLICATION RECEIPT DATE: December 11, 2002 THIS RFA CONTAINS THE FOLLOWING INFORMATION o Purpose of this RFA o Research Objectives o Mechanism(s) of Support o Funds Available o Eligible Institutions o Individuals Eligible to Become Principal Investigators o Special Requirements o Where to Send Inquiries o Letter of Intent o Submitting an Application o Peer Review Process o Review Criteria o Receipt and Review Schedule o Award Criteria o Required Federal Citations: PURPOSE OF THIS RFA The National Institute of Dental and Craniofacial Research (NIDCR) invites investigator-initiated grant applications for support of research on the innate factors of the oral mucosal immune system involved in host resistance to the acquisition and spread of HIV and associated opportunistic infections. RESEARCH OBJECTIVES Background HIV has infected more than 50 million people and AIDS has killed more than 21 million people worldwide. Approximately 40,000 new cases of HIV infection are reported in the United States each year, and the rates of infection are climbing in certain subpopulations of individuals such as women, racial and ethnic minorities, young homosexual men, individuals with addictive disorders, and people over 50 years of age. In response to this pandemic, the NIDCR plans to support research that will 1) increase our understanding of HIV infection in the oral cavity with regards to transmission, 2) develop improved therapy for the opportunistic infections associated with HIV immunosuppression, 3) reduce the incidence of oral tumors associated with AIDS , 4) address the disproportionate impact of AIDS on global health, particularly in the developing countries, with regards to HIV infection and lesions in the oral cavity, and 5) reduce disparities in the incidence of oral HIV infection in the minority populations in the United States. HIV can enter the oral tissues from two directions: exogenously from the oral cavity or endogenously from infected cells or virions in the blood homing to the oral cavity. Endogenous spread is assumed to be controlled by reducing the levels of circulating infected cells or free virions in the blood. Control of such infection is focused on the reduction of HIV in the blood. Exogenous infection, which is possible during receptive oral sex, is controlled by the flow of salivary, hypotonic destruction of infected leukocytes, and inhibition of HIV attachment or entry into oral tissues. Recent evidence indicates that the number of confirmed reports of exogenous oral infection with HIV is extremely low in previously unexposed, seronegative subjects, suggesting that resistance to infection is largely due to antiviral innate factors in the oral tissues and fluids. Similarly, the control of opportunistic infections in the oral cavity in the immunosuppressed AIDS patient is greatly influenced by the innate immune system. Research is sought to explain, at cellular and molecular levels, the relative innate resistance of the oral region to HIV infection and the role of innate factors in the control of opportunistic infections in the immunosuppressed AIDS patients. For example, research is needed on the innate factors in the oropharyngeal region that inhibit HIV interactions with oral epithelial cells, leukocytes, and dendritic cells. In addition the role of mucins, thrombospondin, salivary soluble proteins, histatins, interferon, beta-defensins, secretory leukocyte protease inhibitor (SLPI) and other anti-microbial factors in control of HIV and opportunistic infections is needed. A better understanding of innate factors that control HIV and opportunistic pathogens can suggest novel microbicides and targets for enhanced resistance to infection as well as define underlying differences in susceptibility to HIV infection at other mucosal sites. Applications from both individuals and groups interested in oral AIDS research are encouraged. However, team approaches to these efforts are especially encouraged in the belief that a synergistic blend of expertise and resources could advance the science more quickly. Scope Examples of research that may be supported by this initiative include: o Delineate the macromolecular assemblies that augment the protective barrier of the oral mucosa, and determine how HIV and HIV-associated opportunistic infections compromise this protective barrier. o Determine the unique features of the architectural and cellular composition of the oral mucosa that contribute to resistance to infection. o Determine whether and how innate host defense molecules produced by mucosal epithelial cells contribute to resistance to HIV. o Explore the use of innate factors for their therapeutic potential. o Determine the underlying innate differences in susceptibility to HIV infection and AIDS-related opportunistic infections among oral, gastrointestinal, rectal, and vaginal mucocutaneous tissues. o Determine the influence of HAART (and other anti-HIV therapies) on oral mucosal protection against HIV, and determine whether oral and tonsillar tissues have differential HAART susceptibilities. o Design of synthetic molecules based on innate immune factors that have antiviral activity. o Study therapeutic enhancement of host production of innate factors that have inhibitory effects on HIV and opportunistic pathogens. o Study the role of mucosal innate factors in the prevention of AIDS related oral tumors This list is illustrative and not meant to be inclusive. Investigators are encouraged to propose other studies related to innate immunity to HIV and opportunistic infections in the oral cavity, and to contact the research/science staff listed below to determine whether the project would be responsive to this RFA. MECHANISM OF SUPPORT This RFA will use the NIH individual research project grant (R01) and the exploratory/developmental research grant (R21) award mechanisms. As an applicant you will be solely responsible for the planning, direction, and execution of the proposed project. 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. 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. R21 Applications. R21 proposals should have the potential for truly groundbreaking impact. Use of this mechanism by investigators experienced in innate immunity who wish to explore new approaches to address basic and applied research questions related to host immunity to HIV or opportunistic pathogens is encouraged. Investigators with expertise in fields other than innate immunity who wish to establish new research programs in this area are also encouraged to apply. Applicants are encouraged to contact program staff for advice about choosing the appropriate grant mechanism. The objective of the R21 mechanism is to support innovative, high risk/high impact research requiring preliminary testing or development, exploration of the use of approaches and concepts new to AIDS/HIV infection, research and development of new technologies, techniques or methods, or initial research and development of data upon which significant future research may be built. Applications will be considered as high impact if they demonstrate the potential for ground- breaking, precedent-setting significance, and high risk because they either lack sufficient preliminary data to ensure their feasibility, or involve using a new model system or technique. While this RFA is intended to encourage innovation and high impact research, and while minimal preliminary data are expected to be described in the application, applications should clearly indicate that the proposed research and/or development is scientifically sound, that the qualifications of the investigators are appropriate, and that resources available to the investigators are adequate. FUNDS AVAILABLE The NIDCR intends to commit approximately $2,000,000 in FY 2003 to fund six to ten new and/or competitive continuation grants in response to this RFA. An R01 applicant may request a project period of up to four years. An R21 applicant may request a project period of up to 2 years and a budget for direct costs of up to $150,000 per year. This R21 cap may be exceeded by $25,000 to accommodate the facilities and administrative (indirect) costs associated with collaborative research at another institution. 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 NIDCR 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 this RFA will be reissued. 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 INDIVIDUALS ELIGIBLE TO BECOME PRINCIPAL INVESTIGATORS Any individual with the skills, knowledge, and resources necessary to carry out the proposed research is 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 Grantees will meet annually at or near NIH, Bethesda, MD, to share results, to ensure that the NIDCR has a coherent view of the advances in the field, and to have an opportunity for collective problem solving among investigators. Applicants should budget for travel in their requested budget for the principal investigator and one additional young investigator to attend this annual meeting.

SUPPLEMENTAL INSTRUCTIONS: R21 Applications: All application instructions outlined in the PHS 398 application kit are to be followed with the following modifications for R21 applications: 1. FACE PAGE, Item 6: Up to a total of two years of support may be requested. 2. Items a-d of the Research Plan for the R21 application may not exceed ten (10) pages, including tables and figures. The following information should be taken into account for items a, b and c: o Item a, SPECIFIC AIMS--The instructions for this section suggest that the applicant state "the hypotheses to be tested". Since some applications submitted in response to this RFA may also be design- or problem-driven (e.g., development of novel technologies), or need- driven (initial research to develop a body of data upon which future research will build), hypothesis testing per se may not be the driving force in developing such a proposal and, therefore, may not be applicable. The application should state the hypotheses, design, problem and/or need which will drive the proposed research. o Item b, BACKGROUND AND SIGNIFICANCE--In this section, it is important to identify clearly how the application addresses the specific objectives of this RFA and the purpose of the R21 mechanism. Item c, PRELIMINARY STUDIES/PROGRESS REPORT Minimal preliminary data are required for an R21 application. SPECIFIC INSTRUCTIONS FOR MODULAR GRANT APPLICATIONS: R01 applications requesting up to $250,000 per year in direct costs and all R21 applications must be submitted in a modular grant format. The modular grant format simplifies the preparation of the budget in these applications by limiting the level of budgetary detail. Applicants request direct costs in $25,000 modules. Section C of the research grant application instructions for the PHS 398 (rev. 5/2001) at http://grants.nih.gov/grants/funding/phs398/phs398.html includes step- by-step guidance for preparing modular grants. Additional information on modular grants is available at http://grants.nih.gov/grants/funding/modular/modular.htm. R21 Applications: Applicants may request direct costs in $25,000 modules up to a total of six modules ($150,000). This cap may be exceeded by one module ($25,000) to accommodate the facilities and administrative (indirect) costs associated with collaborative research at another institution. USING THE RFA LABEL: The RFA label available in the PHS 398 (rev. 5/2001) application form must be affixed to the bottom of the face page of the application. Type the RFA number on the label. Failure to use this label could result in delayed processing of the application such that it may not reach the review committee in time for review. In addition, the RFA title and number must be typed on line 2 of the face page of the application form and the YES box must be marked. The RFA label is also available at: http://grants.nih.gov/grants/funding/phs398/label-bk.pdf. SENDING AN APPLICATION TO THE NIH: Submit a signed original copy of the application, including the Checklist, and three signed, photocopies, in one package to: Center For Scientific Review National Institutes Of Health 6701 Rockledge Drive, Room 1040, MSC 7710 Bethesda, MD 20892-7710 Bethesda, MD 20817 (for express/courier service) At the time of submission, two additional copies of the application must be sent to: H. George Hausch, Ph.D. Division of Extramural Activities National Institute of Dental and Craniofacial Research National Institutes of Health Building 45, Room 4AN-44F, MSC 6402 Bethesda, MD 20892-6402 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 responsiveness by the NIDCR. Incomplete and/or non-responsive 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 NIDCR 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 NIDCR National Advisory Council. 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? (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? (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: o PROTECTIONS: The adequacy of the proposed protection for human and animals subjects, or the environment, to the extent they may be adversely affected by the project proposed in the application. o 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) o BUDGET: The reasonableness of the proposed budget and the requested period of support in relation to the proposed research. o R21 APPLICATIONS: The potential for ground-breaking, precedent- setting research, with particular emphasis on novel and innovative approaches, and the potential to stimulate new concepts or approaches regarding important biomedical/behavioral problems, or provide a technique/system of wide applicability. RECEIPT AND REVIEW SCHEDULE Letter of Intent Receipt Date: November 13, 2002 Application Receipt Date: December 11, 2002 Peer Review Date: March 2003 Council Review: June 16, 2003 Earliest Anticipated Start Date: July 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 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 AMENDMENT "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 No. 93.121, Oral Diseases and Disorders Research and is not subject to the intergovernmental review requirements of Executive Order 12372 or Health Systems Agency review. Awards are made under authorization of Sections 301 and 405 of the Public Health Service Act as amended (42 USC 241 and 284) and administered under NIH grants policies described at http://grants.nih.gov/grants/policy/policy.htm and under Federal Regulations 42 CFR 52 and 45 CFR Parts 74 and 92. 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.
