This program announcement replaces PAS-00-028. RESEARCH OBJECTIVES Background Racial and ethnic groups differ considerably in the frequency of diabetes in their populations. For example, rates of type 2 diabetes are particularly high among American Indians, African Americans, Hispanic Americans, and Asian and Pacific Islanders. The microvascular complications of diabetes are a major problem in these groups, not only because their frequency of diabetes is high, but also because there is evidence that complications occur more frequently among individuals with diabetes in these minority populations. However, the reasons for these differences are not well understood. The Diabetes Control and Complications Trial (DCCT), for type 1 diabetes, and the United Kingdom Prospective Diabetes Study (UKDPS), for type 2 diabetes, established the importance of intensive diabetes control in dramatically reducing the devastating complications that result from poorly controlled diabetes. Both the DCCT and the UKPDS demonstrated the efficacy of intensive glucose control in reducing the risk for the microvascular complications of diabetes, such as retinopathy, neuropathy, and nephropathy. In addition, numerous studies have recently demonstrated that intensive blood pressure control is essential in preventing both micro- and macrovascular complications of diabetes. Aggressive management of dyslipidemia has also been shown to decrease macrovascular complications. 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. This difference is particularly striking given the higher incidence of diabetes in these populations. The factors that account for the differing macrovascular disease rates are unknown. For example, the relative contribution of glycemia (versus other risk factors) to cardiovascular risk in these minority populations has not been studied. Objectives and Scope The overall objective of this Program Announcement is to understand racial/ethnic disparities in the development of the micro- and macrovascular complications of diabetes. 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 have been established for investigation of diabetes or other diseases. 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 glucose, blood pressure and lipid control. Such studies of current risks might appropriately be based in large HMOs or clinical practices 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 microvascular (nephropathy, retinopathy, and neuropathy) and macrovascular (cardiovascular disease and stroke) diabetic complications in appropriate representative samples of contemporary populations. o Studies to identify genes which might affect the development and progression 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 compare the contribution of glycemia versus other risk factors (e.g., smoking, hyperlipidemia, body composition, blood pressure) in the development of micro- and macrovascular disease in patients with diabetes, and to study how treatment of these factors may influence rates of development of complications in different racial/ethnic groups. o Studies to investigate environmental 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. o Studies to determine whether different pathophysiologic mechanisms or risk factors are operative among subgroups within racial/ethnic minorities (e.g., different subgroups of Hispanic Americans, such as Mexican Americans, Puerto Ricans, Caribbean Hispanics, Cuban Americans). 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. MECHANISMS OF SUPPORT This PA will use the National Institutes of Health (NIH) research project grant (R01) and the 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 $125,000 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. This PA uses just-in-time concepts. It also uses the modular as well as the non-modular budgeting format. (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.

SENDING AN APPLICATION TO THE NIH: Submit a signed, typewritten original of the application, including the checklist, and five 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) APPLICATION PROCESSING: Applications must be mailed on or before the receipt dates described at http://grants.nih.gov/grants/funding/submissionschedule.htm. The 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 a substantial revision of an application already reviewed, but such application must include an Introduction addressing the previous critique. PEER REVIEW PROCESS Applications submitted for this PA will be assigned on the basis of established PHS referral guidelines. An appropriate scientific review group convened in accordance with the standard NIH peer review procedures (http://www.csr.nih.gov/refrev.htm) will evaluate applications for scientific and technical merit. As part of the initial merit review, all applications will: o Receive a written critique o Undergo a selection process in which only those applications deemed to have the highest scientific merit, generally the top half of applications under review, will be discussed and assigned a priority score o 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 reviewers 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: o Significance o Approach o Innovation o Investigator o Environment (1) Significance: Does this study address an important problem? If the aims of your 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? (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 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? (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? 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. 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. AWARD CRITERIA Applications submitted in response to a PA will compete for available funds with all other recommended applications. The following will be considered in making funding decisions: o scientific merit (as determined by peer review) o availability of funds o programmatic priorities REQUIRED FEDERAL CITATIONS 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 UPDATED "NIH Guidelines for Inclusion of Women and Minorities as Subjects in Clinical Research," 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 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 is available at http://grants.nih.gov/grants/funding/children/children.htm. 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 audit 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 and Safety Monitoring, NIH Guide for Grants and Contracts, June 12, 1998: http://grants.nih.gov/grants/guide/notice-files/not98-084.html). 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 the following website: http://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-039.html. 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. 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. Reviewers are cautioned that their anonymity may be compromised when they directly access an Internet site. HEALTHY PEOPLE 2010 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 PA 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. 93.847, 93.853, 93.867, 93.361, 93.837, 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 Regulation 42 CFR 52 and 45 CFR Parts 74 and 92. The PHS strongly encourages all grant and contract recipients to provide a smoke-free workplace and promote the non-use of all tobacco products.
