Section I. Notice of Funding Opportunity Description

Purpose

The purpose of this notice of funding opportunity (NOFO) is to support highly innovative mechanistic research to accelerate the development of effective precision probiotic interventions using a milestone-driven, biphasic award mechanism. It aims to identify, understand, and develop strategies to address barriers in precision probiotic interventions to account for the heterogenicity in humans that often causes inconsistent probiotic therapeutic responses. Specifically, this NOFO solicits applications that will characterize person-specific features affecting probiotic responses to identify subgroups of probiotic responders, which may then help enhance probiotic clinical outcomes.

The first phase, funded by the R61, will provide for 1 or 2 years of support to identify host biological patterns (e.g., native microbiome, immune system, sex and/or gender, diet, age, genetic background, lifestyle, or health history) that are correlated with differences in probiotic clinical effects using observational or secondary data analysis studies. The second phase, funded under the R33, will support studies to assess the causality of the factors identified in the R61 phase to impact probiotic responsiveness through rigorous mechanistic study designs in animal models or human subjects. This NOFO will not support efficacy or effectiveness clinical trials.

The combined R61/R33 should not exceed 5 years. Transition to the R33 phase requires administrative review by NIH staff and is not guaranteed. Approval of the transition to the R33 phase will be based on the original R61/R33 peer review recommendations, successful completion of transition milestones, any proposed changes to the R33 research based on R61 findings, program priorities, and availability of funds. It is not expected that all applications will continue to the R33 phase.

Support for a single phased award that does not need the R61 Exploratory phase is available in the companion (R33) NOFO, PAR-24-239. 

Background

Naturally occurring microbial-based therapeutics include probiotics—living microorganisms such as bacteria and yeast that are reported to have beneficial health effects. The broad range of reported effects may include alleviation of gastrointestinal symptoms, “strengthening” of the immune system, protection against infectious diseases, improvements in metabolic and mental health, and promotion of early development and general well-being. A major challenge in probiotic research is variation in responses reported for the same intervention, both between trials and among individuals, resulting in significant variability in clinical effects and reported trial outcomes. Such variability may stem from heterogeneity in humans related to  diet, age, genetic background, sex and/or gender, health history, lifestyle, and native gut microbial composition including bacteria, fungi, viruses, archaea, and protozoa. These factors may hamper effective evaluation of clinical efficacy of probiotics and their integration as well as implementation into treatment regimens. One potential solution to tackle this major challenge is to develop a precision probiotics intervention paradigm that has the capability to predict interindividual variations and tailor probiotic strains to individual-specific features. However, this approach requires fundamental understanding of real-life variability of probiotic responses at the individual level as well as development of innovative research tools and strategies to address the complexity of person-specific characteristics.

In April 2022, the National Center for Complementary and Integrative Health (NCCIH) and the Office of Dietary Supplements (ODS) within the National Institutes of Health (NIH), in collaboration with other NIH Institutes, Centers, and Offices as well as the U.S. Department of Agriculture, convened a 2-day workshop, “Precision Probiotic Therapies—Challenges and Opportunities,” to better understand the status and potential future directions of precision probiotic research and to discuss the associated research questions and methodological challenges. The video recordings (Day 1 and Day 2) and executive summary can be found here: https://www.nccih.nih.gov/news/events/precision-probiotic-therapies-challenges-and-opportunities.

During the workshop, several major areas of interest emerged. First, it was recognized that the study designs of most probiotic clinical trials did not fully capture the complex patterns of the gut microbiome, host genetic variability, dietary differences, and environmental exposures of both the microbes and hosts, although all of these are critical considerations for probiotic responsiveness within individuals. Second, although many cross-sectional observational epidemiologic studies have examined these complex patterns, few of their insights have been effectively translated to robust mechanistic studies to test for causality or to rigorous mechanistic clinical trials. Third, understanding the intricate relationships among multiple complex systems, including the microbiome, host, and environment, requires advanced computational and artificial intelligence (AI) approaches.

Research Objectives and Requirements

This NOFO is intended to support mechanistic research for characterization of person-specific features affecting probiotic responses to identify subgroups of probiotic responders and enhance probiotic health outcomes. The NOFO aims to achieve two major objectives using the R61/R33 phased approach.

Objective 1 (R61 Phase): Observational or Secondary Data Analysis Studies (1 or 2 years)

The R61 phase will support observational clinical studies or secondary data analysis to identify patterns of host biology (e.g., native microbiome, immune system, sex and/or gender, diet, age, genetic background, lifestyle, or health history) that are correlated with probiotic usage or interventions.

Examples of activities for R61 phase include but are not limited to:

• Scanning host characteristics to uncover person-specific factors showing highly significant associations with probiotic responses.
• Developing computational analysis or machine learning approach to identify host biological factors.
• Discovering new microbial strains from human samples that are correlated with probiotic activity and improving consistency of probiotic clinical outcomes.

Objective 2 (R33 Phase): Mechanistic Studies (Clinical Trial Optional, remainder of the 5 years)

The R33 phase will use the patterns identified in the R61 phase to test for causality in rigorously designed mechanistic studies in animal models or human subjects.

Examples of activities for the R33 phase include but are not limited to:

• Determining causal effects of the host biological patterns observed in the R61 phase on modifying probiotic responses in clinically relevant preclinical models or human populations.
• Elucidating the mechanisms through which the patterns identified in the R61 phase modify probiotic responses.
• Optimizing and verifying the ability of the computational and machine learning tools developed in the R61 phase to identify host biological patterns in clinically relevant preclinical models or human populations.
• Determining the effects and underlying mechanisms of probiotic activity by the microbial strains identified from the R61 phase.

For applications proposing a clinical trial, note the following definitions and restrictions for this NOFO:

• Clinical trials are research studies in which one or more human subjects are prospectively assigned to one or more interventions (which may include placebo or other control) to evaluate the effects of those interventions on health-related biomedical or behavioral outcomes. The following types of clinical trials are considered to be in scope of this NOFO:
  • Mechanistic trials, defined as studies designed to understand a biological or behavioral process, the pathophysiology of a disease, or the mechanism of action of an intervention (i.e., how an intervention works, but not if it works or is safe).
• Clinical trials designed primarily to determine the clinical feasibility, efficacy, and effectiveness of a probiotic intervention will not be supported under this NOFO.

Preliminary/Supporting Data Requirements

No preliminary data are required for the R61 phase. However, feasibility may be demonstrated through literature citations or preliminary data in animal or human subject studies. Applications should be based on a clear scientific premise, and compelling rationales should be presented for the proposed study and selection of probiotic usage or intervention. 

Regulatory Requirements to Consider

The U.S. Food and Drug Administration (FDA) establishes and enforces the regulatory requirements for clinical research on probiotics when used as drugs. Because NCCIH is a Federal agency, any research supported with NCCIH funding must adhere to relevant FDA regulations. Prior to submitting an application, investigators must contact the FDA to determine whether an Investigational New Drug (IND) application is necessary for the proposed clinical research. For trials using an FDA regulated product and requiring an IND application, the applicant must either hold or be able to reference an open IND for the trial, or the applicant must obtain an IND with no clinical hold prior to any award. If the FDA has granted a waiver for the trial proposed in the application, the applicant can provide this letter as part of the Regulatory Communication Plan. Guidance on the IND evaluation process can be found on the NCCIH Natural Products Clinical Trials Resource webpage: https://www.nccih.nih.gov/grants/natural-products-clinical-trials-resource. 

Applications Not Responsive to This NOFO

The following types of applications will be considered nonresponsive and will be withdrawn prior to review:

• Applications that do not provide clear milestones and a clear path to transition from the R61 to the R33 phase of the award.
• Clinical trials designed primarily to determine the clinical feasibility, efficacy, or effectiveness of a probiotic intervention.

R61 to R33 Transition Criteria and Process

Investigators are expected to describe a set of transition criteria in the form of quantitative milestones (please see Section IV.2 Other Project Information and Research Plan for detailed instructions) that will allow for a definitive assessment of whether the R61 phase provides sufficient evidence to support the R33 phase of this bi-phasic award.

Key evidence in the transition criteria should include thresholds for quantitative measures of host biological patterns proposed to study in the R61 phase. If multiple thresholds are proposed, prioritization should be provided to determine which measure(s) would be moved forward into the R33 phase for further development. Alternatively, the threshold of a composite measure may be described and proposed for R33 phase development if multidimensional measures of host biological patterns are assessed in the R61 phase. Quantitative milestones must include specific thresholds. Examples of metrics include but are not limited to effect sizes (e.g., Cohen’s d >0.3), average area under the curve (e.g., AUC of 0.7), or other metrics of classification accuracy (e.g., sensitivity and specificity metrics of 70%).

It is anticipated that the R61 study should be completed within 20 months post award to allow for a timely submission of the transition request to the R33 phase. Awardees will submit the R33 transition package, which includes a detailed progress report describing advancement toward the initial R61 milestones and a description of how the completed work justifies continuation with the originally proposed R33 studies. These materials will be evaluated by NIH program staff. It is understood that the proposed milestones for the R33 phase may be revised based on activities during the R61 planning phase. In the event of an award, the PD(s)/PI(s) and NIH staff will negotiate a list of milestones for each year of support. Transition to the R33 phase is neither automatic nor guaranteed. R33 funding decisions will be based on the original R61/R33 peer review recommendations, successful completion of R61 milestones, program priorities, and availability of funds.

Applications that only propose R61 or R33 activities will be considered incomplete and will not be accepted for this NOFO. Studies that have already identified unique patterns of interplay and/or putative probiotic strains should be supported by the R33 phase directly. Support for a single phased award that does not need the R61 Exploratory phase is available in the companion R33, PAR-24-239.

Consultation With NIH

Applicants are encouraged to consult with the NIH scientific contacts listed in the NOFO before they begin developing their applications (see Section VII, Agency Contacts). This early contact will provide an opportunity to clarify whether the research topic is a fit with the NOFO’s purpose and priorities.

NIH Institute and Center Interests and Guidance

The National Center for Complementary and Integrative Health (NCCIH)

NCCIH is interested in projects focused on accelerating precision probiotic interventions for specific health conditions within the mission of NCCIH. Topics of special interest include but are not limited to pain, stress, anxiety, sleep and other symptoms, health promotion and restoration, resilience, metabolic and mental disorders, and gastrointestinal dysfunction. Investigators are strongly encouraged to discuss their research plans with the NCCIH scientific/research contact prior to submitting their applications.

The National Institute of Dental and Cranial Facial Research (NIDCR)

NIDCR is interested in projects focused on accelerating precision probiotic interventions for specific health conditions within the mission of NIDCR. Topics of special interest include but are not limited to prevention and treatment of caries, periodontal disease, and oral fungal disease and promotion or restoration of oral health. Investigators are strongly encouraged to discuss their research plans with the NIDCR scientific/research contact prior to submitting their applications. NIDCR will accept Basic Experimental Studies involving Humans (BESH) clinical trial but not mechanistic clinical trial applications through this mechanism.

The NIH Office of Dietary Supplements (ODS)

The NIH Office of Dietary Supplements (ODS) is interested in co-funding projects focused on probiotics for health conditions within the mission of ODS. Topics of special interest include, but are not limited to promoting mucosal immunity, preventing, and ameliorating symptoms associated with digestive diseases, and optimizing health and resilience in diverse populations across the lifespan. The ODS will not support projects focused on diagnosis and/or treatment of disease.  The ODS does not award grants; therefore, applications must be relevant to the objectives of at least one of the participating NIH Institutes and Centers (IC) listed in this announcement. Please contact the relevant IC Scientific/Research Contact(s) listed for questions regarding IC research priorities and funding.

The Office of Research on Women’s Health (ORWH)

ORWH is part of the Office of the Director of NIH and works in partnership with the 27 NIH Institutes and Centers to ensure that women's health research is part of the scientific framework at NIH and throughout the scientific community. Given the knowledge gaps in probiotic research in differential responses to the same probiotic intervention among individuals, there is a crucial need to understand the variability in clinical effects in terms of biological sex and gender. ORWH is interested in supporting projects focused on accelerating precision probiotic interventions for specific women’s health conditions across the lifespan, including but not limited to reproductive health, pregnancy, postpartum health, lactation, vaginal microbiome (bacterial vaginosis), menopause-related symptoms, and autoimmune disorders that are more prevalent in women. In addition, there is a crucial need to address sex influences in probiotic research relevant to women's health, and, where appropriate, include both sexes to better understand the influence of sex as a biological variable on health and disease. Integrating the purposeful accounting for sex as a biological variable (SABV) into biomedical research on probiotic interventions will fill gaps in our knowledge and inform more effective, personalized approaches to control specific health conditions for women and men. For additional guidance, please see the Trans-NIH Strategic Plan for the Health of Women, available on the ORWH website (https://www.nih.gov/women/strategicplan).

The National Institute on Aging (NIA)

The Division of Aging Biology (DAB) in NIA is interested in pre-clinical and clinical research projects focused on understanding the host factors and mechanisms affecting age-related changes in probiotic responses (e.g. immune-senescence and other innate/adaptive immune responses in next-gen probiotic research). Identification of bacterial strains and their metabolites that can be used as probiotics/postbiotics to improve health outcomes in older adults. Mechanistic research on the effects of probiotics applied to understudied anatomical niches (e.g. oral mucosa and periodontal disease; cervicovaginal and bacterial vaginosis; and skin probiotics that improve dermatosis associated with aging). Interrogating mechanistic insights of the probiotic effects on health outcomes across the lifespan. Characterization of factors affecting the efficacy of probiotic intervention (e.g. microbial composition, quorum sensing, role of keystone species, and long-term effects of probiotic treatment). Developing computational analysis and AI/ML algorithms to build predictive models to identify patient subpopulations and critical factors in response to probiotic treatment (e.g. in frailty and older individuals).

The National Cancer Institute (NCI) 

The National Cancer Institute (NCI) supports research on the microbiome's role in cancer, particularly the effects of pre/probiotics on cancer prevention, interception, progression, and treatment. This includes studies on how probiotics interact with host cells and other microbes, influencing cellular functions and tumor development. The Division of Cancer Prevention ( DCP) is interested in investigating the potential benefits of probiotics in cancer prevention. Specifically, DCP is interested in understanding the interaction of probiotics with cancer-associated pathogens, alterations in metabolite production, and reduction of pro-carcinogens. Applications of biomarkers in measuring aforesaid counteractive interactions of probiotics are highly encouraged. Additionally, DCP fosters research on how probiotics impact biofilm composition, functional changes, and their effectiveness in preventing cancer. The Division of Cancer Biology is interested in basic and mechanistic studies on how probiotics affect tumor formation at the molecular level and the interactions between probiotics, host cells, and the resident microbiome, focusing on how these interactions influence cellular signaling, physiology, and metabolism. The Division of Cancer Control and Population Sciences seeks to advance research to demonstrate whether genomic background in different racial and ethnic populations makes them responsive to pre/probiotic exposure and their effects on improving cancer outcomes.

Plan for Enhancing Diverse Perspectives (PEDP):

 The NIH recognizes that teams comprised of investigators with diverse perspectives working together and capitalizing on innovative ideas and distinct viewpoints outperform homogeneous teams. There are many benefits that flow from a scientific workforce rich with diverse perspectives, including: fostering scientific innovation, enhancing global competitiveness, contributing to robust learning environments, improving the quality of the research, advancing the likelihood that underserved populations participate in, and benefit from research, and enhancing public trust. 

To support the best science, the NIH encourages inclusivity in research guided by the consideration of diverse perspectives. Broadly, diverse perspectives can include but are not limited to the educational background and scientific expertise of the people who perform the research; the populations who participate as human subjects in research studies; and the places where research is done. 

This NOFO requires a Plan for Enhancing Diverse Perspectives (PEDP), which will be assessed as part of the scientific and technical peer review evaluation. Assessment of applications containing a PEDP are based on the scientific and technical merit of the proposed project. Consistent with federal law, the race, ethnicity, or sex of a researcher, award participant, or trainee will not be considered during the application review process or when making funding decisions. Applications that fail to include a PEDP will be considered incomplete and will be administratively withdrawn before review. 

The PEDP will be submitted as Other Project Information as an attachment (see Section IV). Applicants are strongly encouraged to read the NOFO instructions carefully and view the available PEDP guidance

Section V. Application Review Information

1. Criteria

Only the review criteria described below will be considered in the review process.  Applications submitted to the NIH in support of the NIH mission are evaluated for scientific and technical merit through the NIH peer review system.

For this particular NOFO, note the following: This NOFO is primarily focused on exploring host biological patterns that may cause inconsistent probiotic health outcomes as proposed in the R61 phase. Secondarily, the R33 phase must determine the reproducibility and causation of these patterns to identify subgroup populations that are more likely to respond to the probiotic intervention and to enhance probiotic clinical outcomes. Appropriate justification for the proposed work can be provided through literature citations, data from other sources, or, when available, from investigator-generated data. Accordingly, reviewers will focus their evaluation on the conceptual framework, the level of innovation, and the potential to significantly advance our knowledge or understanding.

As part of the overall impact score, reviewers should consider and indicate how the Plan to Enhance Diverse Perspectives affects the scientific merit of the project. 

A proposed Clinical Trial application may include study design, methods, and intervention that are not by themselves innovative but address important questions or unmet needs. Additionally, the results of the clinical trial may indicate that further clinical development of the intervention is unwarranted or lead to new avenues of scientific investigation.

Reviewers will provide an overall impact score to reflect their assessment of the likelihood for the project to exert a sustained, powerful influence on the research field(s) involved, in consideration of the following review criteria and additional review criteria (as applicable for the project proposed).

As part of the overall impact score, reviewers should consider and indicate how the Plan to Enhance Diverse Perspectives affects the scientific merit of the project.

Reviewers will consider each of the review criteria below in the determination of scientific merit and give a separate score for each. An application does not need to be strong in all categories to be judged likely to have major scientific impact. For example, a project that by its nature is not innovative may be essential to advance a field.

As applicable for the project proposed, reviewers will evaluate the following additional items while determining scientific and technical merit, and in providing an overall impact score, but will not give separate scores for these items.

As applicable for the project proposed, reviewers will consider each of the following items, but will not give scores for these items, and should not consider them in providing an overall impact score.

2. Review and Selection Process

Applications will be evaluated for scientific and technical merit by (an) appropriate Scientific Review Group(s) convened by CSR, in accordance with NIH peer review policies and practices, using the stated review criteria. Assignment to a Scientific Review Group will be shown in the eRA Commons.

As part of the scientific peer review, all applications will receive a written critique.

Applications may undergo a selection process in which only those applications deemed to have the highest scientific and technical merit (generally the top half of applications under review) will be discussed and assigned an overall impact score.

Applications will be assigned on the basis of established Public Health Service (PHS) referral guidelines to the appropriate NIH Institute or Center. Applications will compete for available funds with all other recommended applications. Following initial peer review, recommended applications will receive a second level of review by the appropriate national advisory council or board. The following will be considered in making funding decisions:

• Scientific and technical merit of the proposed project, including the PEDP, as determined by scientific peer review.
• Availability of funds.
• Relevance of the proposed project to program priorities.

Please note that reviewers will not consider race, ethnicity, age, or gender of a researcher, award participant, or trainee, even in part, in providing critiques, scores, or funding recommendations. NIH will not consider such factors in making its funding decisions.

If the application is under consideration for funding, NIH will request "just-in-time" information from the applicant as described in the NIH Grants Policy Statement Section 2.5.1. Just-in-Time Procedures. This request is not a Notice of Award nor should it be construed to be an indicator of possible funding.

Prior to making an award, NIH reviews an applicant’s federal award history in SAM.gov to ensure sound business practices. An applicant can review and comment on any information in the Responsibility/Qualification records available in SAM.gov.  NIH will consider any comments by the applicant in the Responsibility/Qualification records in SAM.gov to ascertain the applicant’s integrity, business ethics, and performance record of managing Federal awards per 2 CFR Part 200.206 “Federal awarding agency review of risk posed by applicants.”  This provision will apply to all NIH grants and cooperative agreements except fellowships.

3. Anticipated Announcement and Award Dates

After the peer review of the application is completed, the PD/PI will be able to access his or her Summary Statement (written critique) via the eRA Commons. Refer to Part 1 for dates for peer review, advisory council review, and earliest start date.

Information regarding the disposition of applications is available in the NIH Grants Policy Statement Section 2.4.4 Disposition of Applications.

Section VI. Award Administration Information

1. Award Notices

A Notice of Award (NoA) is the official authorizing document notifying the applicant that an award has been made and that funds may be requested from the designated HHS payment system or office. The NoA is signed by the Grants Management Officer and emailed to the recipient’s business official.

In accepting the award, the recipient agrees that any activities under the award are subject to all provisions currently in effect or implemented during the period of the award, other Department regulations and policies in effect at the time of the award, and applicable statutory provisions.

Recipients must comply with any funding restrictions described in Section IV.6. Funding Restrictions. Any pre-award costs incurred before receipt of the NoA are at the applicant's own risk.  For more information on the Notice of Award, please refer to the NIH Grants Policy Statement Section 5. The Notice of Award and NIH Grants & Funding website, see Award Process.

Individual awards are based on the application submitted to, and as approved by, the NIH and are subject to the IC-specific terms and conditions identified in the NoA.

ClinicalTrials.gov: If an award provides for one or more clinical trials. By law (Title VIII, Section 801 of Public Law 110-85), the "responsible party" must register and submit results information for certain “applicable clinical trials” on the ClinicalTrials.gov Protocol Registration and Results System Information Website (https://register.clinicaltrials.gov). NIH expects registration and results reporting of all trials whether required under the law or not. For more information, see https://grants.nih.gov/policy/clinical-trials/reporting/index.htm

Institutional Review Board or Independent Ethics Committee Approval: Recipient institutions must ensure that all protocols are reviewed by their IRB or IEC. To help ensure the safety of participants enrolled in NIH-funded studies, the recipient must provide NIH copies of documents related to all major changes in the status of ongoing protocols.

Data and Safety Monitoring Requirements: The NIH policy for data and safety monitoring requires oversight and monitoring of all NIH-conducted or -supported human biomedical and behavioral intervention studies (clinical trials) to ensure the safety of participants and the validity and integrity of the data. Further information concerning these requirements is found at http://grants.nih.gov/grants/policy/hs/data_safety.htm and in the application instructions (SF424 (R&R) and PHS 398).

Investigational New Drug or Investigational Device Exemption Requirements: Consistent with federal regulations, clinical research projects involving the use of investigational therapeutics, vaccines, or other medical interventions (including licensed products and devices for a purpose other than that for which they were licensed) in humans under a research protocol must be performed under a Food and Drug Administration (FDA) investigational new drug (IND) or investigational device exemption (IDE).

2. Administrative and National Policy Requirements

The following Federal wide and HHS-specific policy requirements apply to awards funded through NIH:

• The rules listed at 2 CFR Part 200, Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards.
• All NIH grant and cooperative agreement awards include the NIH Grants Policy Statement as part of the terms and conditions in the Notice of Award (NoA). The NoA includes the requirements of this NOFO. For these terms of award, see the NIH Grants Policy Statement Part II: Terms and Conditions of NIH Grant Awards, Subpart A: General and Part II: Terms and Conditions of NIH Grant Awards, Subpart B: Terms and Conditions for Specific Types of Grants, Recipients, and Activities.
• If a recipient receives an award, the recipient must follow all applicable nondiscrimination laws. The recipient agrees to this when registering in SAM.gov. The recipient must also submit an Assurance of Compliance (HHS-690). To learn more, see the Laws and Regulations Enforced by the HHS Office for Civil Rights website. 
  • HHS recognizes that NIH research projects are often limited in scope for many reasons that are nondiscriminatory, such as the principal investigator’s scientific interest, funding limitations, recruitment requirements, and other considerations. Thus, criteria in research protocols that target or exclude certain populations are warranted where nondiscriminatory justifications establish that such criteria are appropriate with respect to the health or safety of the subjects, the scientific study design, or the purpose of the research. For additional guidance regarding how the provisions apply to NIH grant programs, please contact the Scientific/Research Contact that is identified in Section VII under Agency Contacts of this NOFO.

All federal statutes and regulations relevant to federal financial assistance, including those highlighted in NIH Grants Policy Statement Section 4 Public Policy Requirements, Objectives and Other Appropriation Mandates.

Recipients are responsible for ensuring that their activities comply with all applicable federal regulations.  NIH may terminate awards under certain circumstances.  See 2 CFR Part 200.340 Termination and NIH Grants Policy Statement Section 8.5.2 Remedies for Noncompliance or Enforcement Actions: Suspension, Termination, and Withholding of Support. 

Not Applicable

3. Data Management and Sharing

Consistent with the 2023 NIH Policy for Data Management and Sharing, when data management and sharing is applicable to the award, recipients will be required to adhere to the Data Management and Sharing requirements as outlined in the NIH Grants Policy Statement. Upon the approval of a Data Management and Sharing Plan, it is required for recipients to implement the plan as described.

4. Reporting

When multiple years are involved, recipients will be required to submit the Research Performance Progress Report (RPPR) annually and financial statements as required in the NIH Grants Policy Statement Section 8.4.1 Reporting. To learn more about post-award monitoring and reporting, see the NIH Grants & Funding website, see Post-Award Monitoring and Reporting.

Recipients will provide updates at least annually on implementation of the PEDP.

A final RPPR, invention statement, and the expenditure data portion of the Federal Financial Report are required for closeout of an award, as described in the NIH Grants Policy Statement Section 8.6 Closeout. NIH NOFOs outline intended research goals and objectives. Post award, NIH will review and measure performance based on the details and outcomes that are shared within the RPPR, as described at 2 CFR Part 200.301.
