Ideally, such a test correlates with long-term changes in blood pressure resulting from a high salt intake. It must be feasible for use in the general population, both in terms of low cost and use on an out-patient basis. RESEARCH OBJECTIVES Background More than 50 million Americans have hypertension, which is a major risk factor for stroke and heart disease. Excess dietary sodium is one of the most important environmental risk factors for hypertension. Besides increasing blood pressure, emerging scientific evidence indicates that excess sodium intake also can have deleterious effects on organs such as the kidney and heart, as well as increase the mortality rate later in life, even in the absence of hypertension. Therefore, strategies to reduce salt intake in the general population are of the utmost importance to public health. General dietary guidelines from the National Heart, Lung, and Blood Institute and from the American Heart Association include the recommendation to limit dietary sodium chloride intake to six grams per day. This recommendation is especially important for individuals with excessive salt-sensitivity, i.e., with exaggerated blood pressure responses to variations in sodium intake. Presently there is no easy test to identify these susceptible individuals. Research in animals and humans has made great strides in understanding the complex molecular pathways that underlie salt sensitivity of blood pressure. Molecular and genetic studies support the decades-old concept that sodium is a major contributing factor to blood pressure. Family studies suggest a heritable contribution to salt sensitivity. Despite an intensive search in recent years for candidate genes for essential hypertension and salt sensitivity, identification of significant effects by single gene polymorphisms remains elusive. Similar to blood pressure itself, salt sensitivity is now known to be a continuous, multigene, multifactorial variable. Among recently discovered molecular markers for salt sensitivity are GRK4gamma gene variants that reduce kidney dopamine activity and the N-terminal fragment of atrial natriuretic peptide prohormone (proANP1-30). Using modern proteomic methodologies, major sodium channel and transporter proteins expressed along the renal tubule, such as the amiloride- sensitive epithelial sodium channel (ENaC), the sodium hydrogen exchanger (NHE3), the thiazide-sensitive sodium chloride cotransporter (NCC), and the bumetanide-sensitive sodium potassium 2chloride cotransporter (NKCC2), have been detected in human as well as rat urine; furthermore, the amount of excreted proteins reflect changes in kidney tissue. Thus, urinalysis of the sodium channel and transporters has the potential to be developed for the clinical detection of disorders of sodium excretion or reabsorption. In hypertension research, the usual method of measuring salt sensitivity is dietary manipulation which typically takes about two weeks. It compares blood pressure after a week of low salt intake to blood pressure after a week of high salt intake, under carefully controlled conditions. A shorter, three-day "acute" clinical test for salt sensitivity includes the infusion of an isotonic saline solution for four hours followed by the administration of a diuretic accompanied by a low salt diet the next day. Blood pressures are measured before, during, and after this procedure. The difference in blood pressure between the salt-replete and salt-deplete states defines the level of salt sensitivity. Both methods are neither practical nor feasible as screening tests for the general population. Further, some studies of such protocols suggest limited reproducibility. There is a great need for an easily administered screening test for salt sensitivity, which could be included in a routine physical examination to identify salt sensitive individuals for targeted preventive efforts. New genomic and proteomic approaches, in addition to recently discovered molecular markers for salt sensitivity, provide evidence that a more concerted effort at developing a sophisticated, practical test has a high likelihood of success. Accurate diagnostic screening test results would provide strong incentives for susceptible individuals to decrease their salt intake. Moreover, a simple screening test could be very useful as a research tool, especially for clinical investigations of the biologic mechanisms underlying salt sensitivity and its pathophysiological consequences. Therefore, this initiative seeks new ideas and approaches from the entrepreneurial, small business community to develop a practical, acute clinical test to diagnose salt sensitivity. Research Topics Examples of research topics that would be considered responsive to this PA include, but are not limited to, the following: o A practical test that can rapidly determine salt sensitivity by demonstrating precise blood pressure changes between states of high and low salt in the body o A test using blood, urine, or buccal tissue to examine a panel of gene variants, proteins, peptides or chemicals that can be used as surrogate markers for salt sensitivity, such as: o Sodium channel and transporter proteins or gene variants, e.g., ENaC, NHE, NCC, and NKCC2 o Regulators of sodium excretion, e.g., proteins that modulate dopamine activity in the kidney and proteins that reflect levels of natriuretic peptides o Regulators of sodium reabsorption, e.g., aldosterone and vasopressin or their modulators MECHANISM(S) OF SUPPORT This PA uses the NIH SBIR and STTR award mechanisms, which are set- aside programs. As an applicant, you will be solely responsible for planning, directing, and executing the proposed project. Future unsolicited, competing-continuation applications based on this project will compete with all SBIR/STTR applications and will be reviewed according to the customary peer review procedures. This PA uses just- in-time concepts. It also uses the modular as well as the non-modular budgeting formats specifically for SBIR and STTR grant applications as described in the current SBIR/STTR Omnibus Solicitation. Specifically, if you are submitting an application budget of $100,000 or less in total costs (direct, F&A and fee) each year, use the modular format. Otherwise follow the instructions for non-modular research grant applications. This program does not require cost sharing as defined in the current NIH Grants Policy Statement at http://grants.nih.gov/grants/policy/nihgps_2001/part_i_1.htm. Except as otherwise stated in this PA, awards will be administered under NIH grants policy as stated in the NIH Grants Policy Statement, March 2001, available at http://grants.nih.gov/grants/policy/nihgps_2001. Applications may be submitted for support as Phase I STTR (R41) or Phase I SBIR (R43) grants; Phase II STTR (R42) or Phase II SBIR (R44) grants. Phase II applications in response to this PA will only be accepted as competing continuations of previously funded NIH Phase I SBIR/STTR awards. The Phase II application must be a logical extension of the Phase I research but not necessarily a Phase I project supported in response to this PA. PROJECT PERIOD AND AMOUNT OF AWARD The SBIR/STTR Omnibus Solicitation indicates the statutory guidelines of funding support and project duration periods for SBIR and STTR Phase I and Phase II awards. For this PA, budgets up to $150,000 total costs per year and time periods up to 2 years may be requested for Phase I. Budgets up to $500,000 total costs per year and up to 3 years may be requested for Phase II. Total costs include direct costs, F&A, and a profit/fee. ELIGIBLE INSTITUTIONS Eligibility requirements are described in the SBIR/STTR Omnibus Solicitation. Only small business concerns are eligible to submit applications. A small business concern is one that, on the date of award for both Phase I and Phase II agreements, meets ALL of the criteria as described in the SBIR/STTR Omnibus Solicitation. 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. On an SBIR application, the principal investigator must have his/her primary employment (more than 50%) with the small business at the time of award and for the duration of the project. The PI on an STTR application may be employed with the small business concern or the participating non- profit research institution as long as s/he has a formal appointment with or commitment to the applicant small business concern, which is characterized by an official relationship between the small business concern and that individual.

AWARD CRITERIA Applications submitted in response to a PA will compete for available funds with all other recommended SBIR and STTR applications. The following will be considered in making funding decisions: o Scientific merit of the proposed project as determined by peer review o Availability of funds o Relevance to program priorities RECEIPT AND REVIEW SCHEDULE See http://grants.nih.gov/grants/funding/sbirsttr_receipt_dates.htm 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. http://www.hhs.gov/ohrp/humansubjects/guidance/45cfr46.htm MONITORING PLAN AND DATA AND SAFETY 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 and Safety 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: (if applicable) 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. STANDARDS FOR PRIVACY OF INDIVIDUALLY IDENTIFIABLE HEALTH INFORMATION: The Department of Health and Human Services (DHHS) issued final modification to the "Standards for Privacy of Individually Identifiable Health Information", the "Privacy Rule," on August 14, 2002. The Privacy Rule is a federal regulation under the Health Insurance Portability and Accountability Act (HIPAA) of 1996 that governs the protection of individually identifiable health information, and is administered and enforced by the DHHS Office for Civil Rights (OCR). Those who must comply with the Privacy Rule (classified under the Rule as "covered entities") must do so by April 14, 2003 (with the exception of small health plans which have an extra year to comply). Decisions about applicability and implementation of the Privacy Rule reside with the researcher and his/her institution. The OCR website (http://www.hhs.gov/ocr/) provides information on the Privacy Rule, including a complete Regulation Text and a set of decision tools on "Am I a covered entity?" Information on the impact of the HIPAA Privacy Rule on NIH processes involving the review, funding, and progress monitoring of grants, cooperative agreements, and research contracts can be found at http://grants.nih.gov/grants/guide/notice-files/ NOT-OD-03-025.html. 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 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.
