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 Request for Applications (RFA), Basic Biology and Pathogenesis of Human Tuberculosis, is related to the priority areas of immunity, infectious diseases, and HIV infection. Potential applicants may obtain a copy of "Healthy People 2000" (Full Report: Stock No. 017-001-00474-0) or "Healthy People 2000" (Summary Report: Stock No. 017-001-00473-1) through the Superintendent of Documents, Government Printing Office, Washington, DC 20402-9325 (telephone 202-783-3238). ELIGIBILITY REQUIREMENTS Domestic and foreign non-profit and for-profit organizations and institutions, governments and their agencies, are eligible to apply. Minorities and women are encouraged to apply. Foreign institutions are not eligible for the First Independent Research Support and Transition (FIRST) (R29) award. Applications from or involving minority institutions or women's institutions are encouraged. MECHANISM OF SUPPORT This RFA will use the National Institutes of Health (NIH) individual research project grant (R01), and the FIRST (R29) award. Responsibility for the planning, direction, and execution of the proposed project will be solely that of the applicant. The total project period for applications submitted in response to this RFA may not exceed five years. This RFA is a one-time solicitation. Future unsolicited competing applications will compete with investigator-initiated applications and be reviewed according to customary review procedures. FUNDS AVAILABLE The estimated total funds (direct and indirect costs) available for the first year of this program will be $1,000,000. In fiscal year 1993, the NIAID plans to fund at least four R01s and/or R29s. This level of support is dependent on the receipt of a sufficient number of applications of high scientific merit. RESEARCH OBJECTIVES Background A century ago, tuberculosis (TB) was a leading cause of death in the United States. Through the efforts of researchers, physicians, and public health officials, as well as through improvements in living conditions and the introduction of effective drug therapy, the number of TB cases and deaths in the United States declined steadily for 40 years. This trend stopped in 1985. The number of cases is now increasing. The new cases of TB in the U.S. reported to the Centers for Disease Control were 22,517 in 1987, 23,495 in 1989 and 26,283 in 1991. This resurgence of TB is a matter of grave concern. In the United States TB is responsible for about 2,000 deaths annually. An estimated 10 million persons in the United States are presently infected with the TB organism and have the potential to develop clinical TB (active disease) at some time in their lives. Globally, TB is an even more serious threat. An estimated 8 million new TB cases and 2.9 million TB deaths occur each year. (Science, Vol. 21, p1055-1064, Aug. 21, 1992). The recent rise in tuberculosis cases reported in the United States and elsewhere is attributed, at least in part, to the heightened susceptibility to TB infections of HIV-positive persons. Other factors, including intravenous drug abuse, the increased influx of immigrants from less developed nations, and poor socio-economic status, also contribute to this rise. The concern of health officials about the number of cases is intensified by the recent growth in the number of isolates of multi-drug-resistant M. tuberculosis (MDRTB). The background to these developments is documented in publications of the Centers for Disease Control (e.g., Morbidity and Mortality Weekly Reports, March 1, 1991, Vol. 40, No. 8 and June 19, 1992, Vol. 41, No. RR-11). Despite advances in diagnosis and treatment made during the 100 years since the identification of M. tuberculosis, serious problem areas remain. A clearer understanding of the structural and functional biology of the organism could provide insight into both pathogenic mechanisms and the immunologic responses evoked in the infected host. Sensitive and specific methods for rapid, reliable diagnosis of tuberculosis are urgently needed. Treatment of active tuberculosis also remains an area of interest. The means to shorten the treatment course and hence improve both patient compliance and lower costs is an important goal. The emergence of resistant organisms is a matter of particular concern to health officials. The case fatality rate for TB resistant to two or more drugs (MRDTB) is 40 to 60 percent and the overall costs of treatment of these cases is five times higher. Patients often fail to complete the long term drug treatments needed to cure TB infections, an action that encourages both relapse and the emergence of resistant organisms. In conjunction with this, methodologies for the rapid, reliable identification of MDRTB in clinical specimens and in laboratory cultures are needed. Progress in all areas of clinical tuberculosis research is contingent upon an improved understanding of the basic structural and molecular biology of M. tuberculosis. Studies of the immunology, pathogenesis, virulence factors, and molecular bacteriology of this organism are thus of great importance if we are to achieve our clinical research objectives. Research Objectives and Scope Applications are encouraged that involve a coordinated multi-disciplinary approach to investigate M. tuberculosis and/or its interactions with its host (including animal models). Applications that involve an integration of basic and clinical sciences will be given favorable consideration. The aim of these efforts should be a greater understanding of mechanisms of pathogenesis, immune evasion, virulence factors or host response and/or lead to improvements in the diagnosis, treatment or prevention of tuberculosis. These areas may include, but are not limited to, the following: o Identify and characterize virulence factors important in the pathogenesis of tuberculosis. o Characterize the role(s) of tumor necrosis factor and other cytokines and soluble factors that affect the course of the disease. o Develop improved in vitro or animal models for basic and applied studies. o Characterize cell surface antigens and describe their interactions with components of the host immune system. o Characterize the response of the host to natural infection and define the correlates of protective immunity. o Characterize immune mechanisms underlying successful inhibition of growth and persistence of tubercle bacilli in the body. Define the mechanisms by which M. tuberculosis persists in a quiescent state, and conditions under which reactivation of infection may occur. o Characterize mechanisms underlying drug resistance, particularly in MDRTB. o Develop improved methods for rapid, reliable identification of drug-sensitive and drug-resistant strains of M. tuberculosis, including MDRTB, in clinical specimens and in laboratory cultures. The areas outlined above are not intended to be all-inclusive, nor are they all required. All research strategies designed to improve markedly the understanding of the pathogenic mechanisms operative in tuberculosis, or with the potential for improving current diagnosis, treatment, and prevention modalities, are encouraged. SPECIAL REQUIREMENTS NIAID program staff will organize annual meetings that Principal Investigators and other key members (as designated by the Principal Investigators) of the projects will be encouraged to attend to discuss progress. This will facilitate overall program planning and development, evaluation of the feasibility of planned approaches, and will promote productive interactions among the awardees. Funds for travel to these meetings should be included in the budget. NIAID program staff will also ensure and arrange for the participation in these meetings of investigators from other relevant NIAID-supported tuberculosis research projects, if appropriate, in order to further promote productive interactions. STUDY POPULATIONS SPECIAL INSTRUCTIONS TO APPLICANTS REGARDING IMPLEMENTATION OF NIH POLICIES CONCERNING INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH STUDY POPULATIONS NIH policy is that applicants for NIH clinical research grants and cooperative agreements will be required to include minorities and women in study populations so that research findings can be of benefit to all persons at risk of the disease, disorder or condition under study; special emphasis should be placed on the need for inclusion of minorities and women in studies of diseases, disorders and conditions which disproportionately affect them. This policy is intended to apply to males and females of all ages. If women or minorities are excluded or inadequately represented in clinical research, particularly in proposed population-based studies, a clear compelling rationale should be provided. The composition of the proposed study populations must be described in terms of gender and racial/ethnic group, together with a rationale for its choice. In addition, gender and racial/ethnic issues should be addressed in developing a research design and sample size appropriate for the scientific objectives of the study. This information should be included in the form PHS 398 (rev. 9/91) in Sections 1-4 of the Research Plan AND summarized in Section 5, Human Subjects. Applicants are urged to assess carefully the feasibility of including the broadest possible representation of minority groups. However, NIH recognizes that it may not be feasible or appropriate in all research projects to include representation of the full array of United States racial/ethnic minority populations (i.e., Native Americans including American Indians or Alaskan Natives, Asian/Pacific Islanders, Blacks, Hispanics). The rationale for studies on single minority population groups should be provided. For the purpose of this policy, clinical research includes human biomedical and behavioral studies of etiology, epidemiology, prevention (and preventive strategies), diagnosis, or treatment of diseases, disorders or conditions, including but not limited to clinical trials. The usual NIH policies concerning research on human subjects also apply. Basic research or clinical studies in which human tissues cannot be identified or linked to individuals are excluded. However, every effort should be made to include human tissues from women and racial/ethnic minorities when it is important to apply the results of the study broadly, and this should be addressed by applicants. For foreign awards, the policy on inclusion of women applies fully; since the definition of minority differs in other countries, the applicant must discuss the relevance of research involving foreign populations groups to the United States' populations, including minorities. If the required information is not contained within the application, the application will be returned. Peer reviewers will address specifically whether the research plan in the application conforms to these policies. If the representation of women or minorities in a study design is inadequate to answer the scientific question(s) addressed AND the justification for the selected study population is inadequate, it will be considered a scientific weakness or deficiency in the study design and will be reflected in assigning the priority score to the application. All applications for clinical research submitted to NIH are required to address these policies. NIH funding components will not support applications that do not comply. LETTER OF INTENT Prospective applicants are asked to submit, by January 22, 1993, a letter of intent that includes a descriptive title of the proposed research, the name, address and telephone number of the Principal Investigator, the identities of other key personnel and the participating institution, and the number and title of the RFA in response to which the application may be submitted. Although a letter of intent is not required, is not binding, and does not enter into the review of subsequent applications, the information allows NIAID staff to estimate the potential review workload and avoid conflict of interest in the review. The letter of intent is to be sent to Dr. Olivia Preble at the address listed under INQUIRIES. APPLICATION PROCEDURES The research grant application form PHS 398 (rev. 9/91) is to be used in applying for these grants. These forms are available at most institutional offices of sponsored research or business offices and from the Office of Grants Inquiries, Division of Research Grants, National Institutes of Health, Westwood Building, Room 449, Bethesda, MD 20892, telephone 301/496-7441. The deadline for receipt of applications in response to this RFA is March 23, 1993. Applicants for FIRST (R29) awards must include at least three sealed letters of reference attached to the face page of the original application. FIRST award applications submitted without the required number of reference letters will be considered incomplete and will be returned without review. Applicants from institutions that have a General Clinical Research Center (GCRC) funded by the NIH National Center of Research Resources may wish to identify the Center as a resource for conducting the proposed research. If so, a letter of agreement from the GCRC Program Director should be included in the application material. The RFA label available in the application form must be affixed to the bottom of the face page. 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 "Yes" box must be marked and the RFA title (Basic Biology and Pathogenesis of Human Tuberculosis) and number (AI-93-03) must be typed on line 2a of the face page of the application. Submit a signed, typewritten original of the application, including the Checklist and three signed single-sided photocopies, in one package, to: Division of Research Grants National Institutes of Health Westwood Building, Room 240 Bethesda, MD 20892** At the time of submission to DRG, two additional exact copies must be sent to Dr. Olivia Preble at the address listed under INQUIRIES. Applications received after the deadline will be returned without review. The Division of Research Grants (DRG) will not accept any application in response to this announcement that is essentially the same as one currently pending initial review, unless the applicant withdraws the pending application. The DRG will not accept any application that is essentially the same as one already reviewed. This does not exclude the submission of substantial revisions of application already reviewed. These applications must, however, include an introduction addressing the previous critique. REVIEW CONSIDERATIONS Upon receipt, applications and supporting material will be reviewed by the DRG for completeness and by NIAID staff for responsiveness to the RFA. Incomplete applications will be returned without further consideration. If the application is not responsive to the RFA, NIAID staff will contact the applicant to determine whether to return the application or submit it for review in competition with unsolicited applications at the next review cycle. Applications may be triaged by an NIAID peer review group on the basis of relative competitiveness. The NIH will withdraw from further competition those applications judged to be non-competitive for award and notify the applicant Principal Investigator and institutional official. Those applications that are complete and responsive will be evaluated in accordance with the criteria stated below for scientific/technical merit by an appropriate peer review group convened by the NIAID. The second level of review will be provided by the National Advisory Allergy and Infectious Diseases Council. Review criteria for applications received in response to an RFA are generally the same as those for unsolicited applications, namely: o Scientific, technical, or medical significance and originality of the proposed research. o Appropriateness and adequacy of the experimental approach and methodology proposed to accomplish the research. o Qualification and research experience of the Principal Investigator and staff, particularly, but not exclusively, in the area of the proposed research. o Availability of resources to carry out the proposed research. o Appropriateness of the proposed budget and duration of the project in relation to the proposed research. AWARD CRITERIA The anticipated date of award is September 30, 1993. The primary criterion for award is technical and scientific merit as judged by peer review and reflected in the priority score. Additional criteria are availability of funds and the number of meritorious applications received in response to this RFA.
