RACE/ETHNIC DISPARITIES IN THE INCIDENCE OF DIABETES COMPLICATIONS Release Date: December 15, 1999 (see replacement PA-02-165) PA NUMBER: PAS-00-028 National Institute of Diabetes and Digestive and Kidney Diseases THIS PA USES THE "MODULAR GRANT" AND "JUST-IN-TIME" CONCEPTS. IT INCLUDES DETAILED MODIFICATIONS TO STANDARD APPLICATION INSTRUCTIONS THAT MUST BE USED WHEN PREPARING APPLICATIONS IN RESPONSE TO THIS PA. PURPOSE This Program Announcement (PA) solicits research to investigate (1) differences among contemporary populations in the United States, categorized by race-ethnicity and other factors, in risk factors for complications of diabetes and in rates of these complications; and (2) the extent to which factors, including inherent metabolic and genetic variations, medical care, socioeconomic status, and behavioral factors account for these differences. HEALTHY PEOPLE 2000 The Public Health Service (PHS) is committed to achieving the health promotion and disease prevention objectives of "Healthy People 2000," a PHS- led national activity for setting priority areas. This PA, Race/Ethnic Disparities in Diabetes Complications, is related to the priority area of diabetes and chronic disabling conditions. Potential applicants may obtain a copy of "Healthy People 2000" at http://odphp.osophs.dhhs.gov/pubs/hp2000 ELIGIBILITY REQUIREMENTS Applications may be submitted by domestic for-profit and nonprofit organizations, public and private, such as universities, colleges, hospitals, laboratories, units of State and local governments, and eligible agencies of the Federal Government. Racial/ethnic minority individuals, women, and persons with disabilities are encouraged to apply as principal investigators. MECHANISM OF SUPPORT This PA will use the National Institutes of Health (NIH) research project grant (R01) and Exploratory/Development Research Grant (R21) award mechanisms. Responsibility for the planning, direction, and execution of the proposed project will be solely that of the applicant. The total project period for an R01 application submitted in response to this PA may not exceed 5 years. The R21 awards are to demonstrate feasibility and to obtain preliminary data testing innovative ideas that represent clear departure from ongoing research interests. These grants are intended to 1) provide initial support for new investigators; 2) allow exploration of possible innovative new directions for established investigators; and 3) stimulate investigators from other areas to lend their expertise to research within the scope of this solicitation. Applicants for the R21 must limit their requests to $100,000 direct costs per year and are limited to two years. These R21 grants will not be renewable; continuation of projects developed under this program will be through the regular research grant (R01) program. Specific application instructions have been modified to reflect "MODULAR GRANT" and "JUST-IN-TIME" streamlining efforts being examined by the NIH. Complete and detailed instructions and information on Modular Grants can be found at http://grants.nih.gov/grants/funding/modular/modular.htm FUNDS AVAILABLE $2 million per year will be set aside by NIDDK for three years to fund applications relevant to this PA. Funding is dependent on the receipt of a sufficient number of applications of high scientific merit and on the availability of funds for this purpose. This PA will remain active for three years, through the October/November 2003 receipt date, after which applications submitted within the scientific scope of this PA will compete without benefit of a set aside of funds. RESEARCH OBJECTIVES Background Extant information on the incidence of complications of diabetes in the United States is often based on community populations or large clinic populations in which the onset of diabetes occurred several decades ago. These studies generally found a striking and large excess of microvascular disease in minority racial and ethnic groups, including Native Americans, African Americans, Hispanic Americans, and Asian and Pacific Islanders. Whether these disparities in diabetes complications continue to occur in contemporary diabetic patients is not known. For example, new advances in treating diabetes and blood pressure may lessen the race-ethnic differentials in glycemic control and blood pressure control. This might, in turn, lead to decreases in the risk for diabetes-related microvascular complications in minorities, relative to risk in the majority Caucasian population. Despite improvements in health care, some of the racial differences in diabetic complications may be explained by differences in availability and quality of health services. There may be differences by race/ethnicity and socioeconomic status in self-care practices, health care provider practices, and/or access to quality health care and prevention services that directly impinge on the frequency and magnitude of risk factors for diabetes complications and the intensity of medical care for early stages of complications to prevent progression to end-stage disease. In addition to differences in blood glucose, lipid and blood pressure control, which may be modified by improved medical care, genetic susceptibility and other biological risk factors may contribute in unknown ways that lead to complications. This is suggested by the clustering of complications (especially nephropathy) within families and by the excess risk of retinopathy in Hispanics versus non-Hispanics that remains when the degree of hyperglycemic exposure is taken into account. Finally, lifestyle, psychosocial factors, stress, family structure, social support, diet and culture, and socioeconomic status vary among racial and ethnic minorities and may contribute to differential risk of developing diabetes complications and progression of complications. Little is known about how these behavioral factors influence the risk of complications and the effectiveness of interventions designed to prevent or reduce diabetes complications in racial and ethnic minority groups. Identification of these divergent etiologies and quantification of their correlation to risk have important implications for prevention and amelioration of microvascular complications. Such information might improve the effectiveness of treatment to reduce the disparities in the incidence in diabetes complications among racial and ethnic groups. In contrast to microvascular complications, racial and ethnic minorities with diabetes often have lower rates of macrovascular disease than Caucasian population groups. Angina, myocardial infarction, and other forms of coronary heart disease appear to be less common in African Americans, Mexican Americans and Native Americans than in non-Hispanic whites. The factors that account for the differing macrovascular disease rates are unknown. Objectives and Scope The overall objectives are to determine 1) whether minority race-ethnic populations continue to differ in their risk for microvascular and macrovascular complications, and, if so, 2) the reasons for these differences. It is recognized that both biologic and non-biologic factors may be operating in these populations. Approaches may include metabolic, genetic and/or epidemiologic studies in representative populations. Advantage might be taken of extant cohort studies that may have been established for investigation of diabetes or other diseases. A collaboration among investigators of these established cohorts would be desirable, so that these studies might jointly develop protocols and evaluate findings. Alternatively, investigators may propose to start a new cohort, appropriately powered, to capture the current risks and outcomes in the era of new medications for glycemic control, blood pressure control, and lipid control. Such studies of current risks might appropriately be based in large HMOs with structure and data management practices conducive to efficient and cost-effective analyses. Investigators are encouraged to incorporate appropriate surrogate markers for complications into study design to shorten the duration of studies. Such surrogate markers might include early indicators of end-stage complications (background retinopathy, albuminuria, serum creatinine, basement membrane thickening, EKG, carotid ultrasound). Appropriate topics for investigation would include but are not limited to: o Epidemiologic studies to determine the rates of the micro- and macrovascular diabetic complications in appropriate representative samples of contemporary populations. o Studies to identify genes which might affect the development of micro- and macrovascular complications in different populations o State-of-the-art, hypothesis-driven metabolic studies to determine whether there are differences in metabolism, insulin sensitivity, energy expenditure, beta cell function, and body composition that might influence glycemic control and risk of complications in different populations. o Studies to investigate factors, such as medical care, behavior and lifestyle, and socioeconomic status, that may contribute to risk for development and progression of complications. Such studies could incorporate culturally-specific lifestyle factors into treatment and prevention strategies to reduce risk across racial and ethnic groups. Understanding the basis for differing susceptibilities could provide information that would lead to specific therapies likely to be useful in various subpopulations at high risk for the development of diabetes complications. INCLUSION OF WOMEN AND MINORITIES IN RESEARCH INVOLVING HUMAN SUBJECTS It is the policy of the NIH that women and members of minority groups and their subpopulations must be included in all NIH supported biomedical and behavioral research projects involving human subjects, unless a clear and compelling rationale and justification is provided 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 research involving human subjects should read the "NIH Guidelines For Inclusion of Women and Minorities as Subjects in Clinical Research," which have been published in the Federal Register of March 28, 1994 (FR 59 14508-14513) and in the NIH Guide For Grants and Contracts, Vol. 23, No. 11, March 18, 1994, available on the web at http://grants.nih.gov/grants/guide/notice-files/not94-100.html INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN SUBJECTS. It is the policy of NIH 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 was published in the NIH Guide for Grants and Contracts, March 6, 1998, and is available at the following URL address: http://grants.nih.gov/grants/guide/notice-files/not98-024.html Investigators may also obtain copies of these policies from the program staff listed under INQUIRIES. Program staff may also provide additional relevant information concerning the policy. APPLICATION PROCEDURES Applications are to be submitted on the grant application form PHS 398 (rev. 4/98) and will be accepted at the standard application deadlines as indicated in the application kit. Application kits are available at most institutional offices of sponsored research, or may be obtained from the Division of Extramural Outreach and Information Resources, National Institutes of Health, 6701 Rockledge Drive, MSC 7910, Bethesda, MD 20892-7910, telephone 301- 435-0714, email: GrantsInfo@nih.gov. Applicants planning to submit an investigator-initiated new (type 1) competing continuation (type 2), competing supplement, or any amended/revised version of the preceding grant application types requesting $500,000 or more in direct costs for any year are advised that he or she must contact the NIDDK program staff before submitting the application, i.e., as plans for the study are being developed. Furthermore, the application must obtain agreement from the staff that the NIDDK will accept the application for consideration for award. Finally, the applicant must identify, in a cover letter sent with the application, the staff member and Institute or Center who agreed to accept assignment of the application. This policy requires an applicant to obtain agreement for acceptance of both any such application and any such subsequent amendment. Refer to the NIH Guide for Grants and Contracts, March 20, 1998 at http://grants.nih.gov/grants/guide/notice-files/not98-030.html. The modular grant concept establishes specific modules in which direct costs may be requested as well as a maximum level for requested budgets. Only limited budgetary information is required under this approach. The just-in-time concept allows applicants to submit certain information only when there is a possibility for an award. It is anticipated that these changes will reduce the administrative burden for the applicants, reviewers, and Institute staff. The research grant application form PHS 398 (rev. 4/98) is to be used in applying for these grants, with the modifications noted below. BUDGET INSTRUCTIONS Modular Grant applications for support under the R01 mechanism will request direct costs in $25,000 modules, up to a total direct cost request of $250,000 per year. (Applications that request more than $250,000 direct costs in any year must follow the traditional PHS 398 application instructions.) Applications for R21 grants will request up to 4 modules in direct costs. The total direct costs must be requested in accordance with the program guidelines and the modifications made to the standard PHS 398 application instructions described below: PHS 398 o FACE PAGE: Items 7a and 7b should be completed, indicating Direct Costs (in $25,000 increments up to a maximum of $250,000) and Total Costs [Modular Total Direct plus Facilities and Administrative (F&A) costs] for the initial budget period. Items 8a and 8b should be completed indicating the Direct and Total Costs for the entire proposed period of support. o DETAILED BUDGET FOR THE INITIAL BUDGET PERIOD: Do not complete Form Page 4 of the PHS 398. It is not required and will not be accepted with the application. o BUDGET FOR THE ENTIRE PROPOSED PERIOD OF SUPPORT: Do not complete the categorical budget table on Form Page 5 of the PHS 398. It is not required and will not be accepted with the application. o NARRATIVE BUDGET JUSTIFICATION: Prepare a Modular Grant Budget Narrative page. (See http://grants.nih.gov/grants/funding/modular/modular.htm for sample pages.) At the top of the page, enter the total direct costs requested for each year. This is not a Form page. o Under Personnel, list key project personnel, including their names, percent of effort, and roles on the project. No individual salary information should be provided. However, the applicant should use the NIH appropriation language salary cap and the NIH policy for graduate student compensation in developing the budget request. For Consortium/Contractual costs, provide an estimate of total costs (direct plus facilities and administrative) for each year, each rounded to the nearest $1,000. List the individuals/organizations with whom consortium or contractual arrangements have been made, the percent effort of key personnel, and the role on the project. Indicate whether the collaborating institution is foreign or domestic. The total cost for a consortium/contractual arrangement is included in the overall requested modular direct cost amount. Include the Letter of Intent to establish a consortium. Provide an additional narrative budget justification for any variation in the number of modules requested. o BIOGRAPHICAL SKETCH: The Biographical Sketch provides information used by reviewers in the assessment of each individual's qualifications for a specific role in the proposed project, as well as to evaluate the overall qualifications of the research team. A biographical sketch is required for all key personnel, following the instructions below. No more than three pages may be used for each person. A sample biographical sketch may be viewed at: http://grants.nih.gov/grants/funding/modular/modular.htm - Complete the educational block at the top of the form page; - List position(s) and any honors; - Provide information, including overall goals and responsibilities, on research projects ongoing or completed during the last three years. - List selected peer-reviewed publications, with full citations; o CHECKLIST: This page should be completed and submitted with the application.

All appropriate exclusions must be applied in the calculation of the F&A costs for the initial budget period and all future budget years. o The applicant should provide the name and phone number of the individual to contact concerning fiscal and administrative issues if additional information is necessary following the initial review. The program announcement title and number must be typed on line 2 of the face page of the application form and the YES box must be marked. Submit the signed, original, single-sided application, including the Checklist, along with five signed photocopies and five collated sets of appendix materials 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) The Center for Scientific Review (CSR) will not accept any application in response to this PA 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. REVIEW CONSIDERATIONS Applications will be assigned on the basis of established Public Health Service referral guidelines. Applications will be evaluated for scientific and technical merit by an appropriate scientific review group convened in accordance with the standard NIH peer review procedures. As part of the initial merit review, all applications will receive a written critique and undergo a process in which only those applications deemed to have the highest scientific merit, generally the top half of applications under review, will be discussed, assigned a priority score, and receive a second-level review by the appropriate national advisory council or 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, reviewer will be asked to discuss the following aspects of the application in order to judge the likelihood that the proposed research will have a substantial impact on the pursuit of these goals. Each of these criteria will be addressed and considered in assigning the overall score, weighting them as appropriate for each application. Note that the 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. o 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? o 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? o Innovation: Does the project employ novel concepts, approaches, or method? Are the aims original and innovative? Does the project challenge existing paradigms or develop new methodologies or technologies? o 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)? o 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? In addition to the above criteria, in accordance with NIH policy, all applications will also be reviewed with respect to the following: o Adequacy of plans to include both genders, minorities and their subgroups, and children as appropriate for the scientific goals of the research. Plans for the recruitment and retention of subjects will also be evaluated. o The reasonableness of the proposed budget and duration to the proposed research. o The adequacy of the proposed protection of humans, animals, or the environment, to the extent that they may be adversely affected by the project proposed in the application. o Availability of special opportunities for furthering research programs through the use of unusual talent resources, populations, or environmental conditions in other countries which are not readily available in the United States or which provide augmentation of existing U.S. resources. AWARD CRITERIA Applications will compete for available funds with all other recommended applications assigned to the National Institute of Diabetes and Digestive and Kidney Diseases. The following will be considered in making funding decisions: o Quality of the proposed project as determined by peer review; o Availability of funds; o Program priority. INQUIRIES Inquiries are encouraged. The opportunity to clarify any issues or questions from potential applicants is welcome.
