Funding Opportunity Purpose

This Notice of Funding Opportunity (NOFO) encourages applications for investigator-initiated mid-phase clinical trials of natural products (i.e., botanicals, dietary supplements, and probiotics), which have a strong scientific premise to justify further clinical testing. For this NOFO, natural products include promising nutritional regimens that standardize the amount of a specific naturally occurring nutritional compound (e.g., omega-3 fatty acids, anthocyanidins, or polyphenols) and have compelling preliminary evidence. All applications submitted under this NOFO must be supported by sufficient preliminary data demonstrating bioavailability (if applicable) and documentation that the natural product produces a reproducible and measurable impact on target engagement (i.e., measure of the mechanism of action). Only in cases when it is not possible/practical to measure target engagement in the patient population of interest or when there is a fundamental understanding of the product’s mechanism of action will this preliminary data requirement be waived. 

Applications submitted to this NOFO should propose a mid-phase clinical trial to do the following: determine the optimal dose or formulation of a given natural product for use in a future multi-site efficacy trial; or determine which patient phenotypes will be responders versus non-responders to the natural product to inform inclusion/exclusion criteria of a future efficacy trial. Clinical trials submitted under this NOFO are expected to be hypothesis based, milestone-driven, and directly related to the research priorities and mission of NCCIH. This NOFO will not support single-site or multi-site efficacy or effectiveness trials, nor will it support trials to test natural products for the treatment or prevention of cancer. 

Applicants are encouraged to contact the appropriate NCCIH Scientific/Research contact for the area of science for which they are planning to develop an application prior to submitting to this NOFO. 

This Notice of Funding Opportunity (NOFO) requires a Plan for Enhancing Diverse Perspectives (PEDP).

Funding Opportunity Goal(s)

The National Center for Complementary and Integrative Health (NCCIH) provides funding for research into complementary and integrative health approaches. Research constituting a rigorous evidence base for complementary health approaches will be developed through a range of research strategies including basic and translational research, and clinical investigation.

Section I. Notice of Funding Opportunity Description

Background  

The National Center for Complementary and Integrative Health (NCCIH) is committed to the rigorous investigation of promising complementary and integrative health approaches with nutritional therapeutic inputs (often called natural products). Promising natural products (i.e., botanicals, probiotics, and products marketed as dietary supplements) have compelling preclinical or preliminary clinical evidence for potential health benefit. For this notice of funding opportunity (NOFO), natural products include promising nutritional regimens that standardize the amount of a specific naturally occurring nutritional compound (e.g., omega-3 fatty acids, anthocyanidins, or polyphenols) and have compelling preliminary evidence suggesting potential benefit in treating a condition, disorder, or disease.

Nutritional intervention research in humans is complicated by the complex and varied background nutritional status and dietary intake of participants in clinical trials. To enhance rigor, reproducibility, and generalizability, it is important that trials of natural products that are part of the regular or occasional dietary intake include rigorous methods to account for the dietary intake and heterogeneity across participants (e.g., assessment of nutritional status; collection of data about dietary intake at baseline and throughout the trial; collection of data about factors that may impact absorption or metabolism of the natural product; rigorous study design to ensure balance across study arms with strategies such as stratified randomization; or rigorous statistical methods to examine treatment heterogeneity through prespecified subgroup analyses or analyses of effect modification by background nutritional status or other participant characteristics on target engagement or clinical outcomes).

Clinical trials of natural products are maximally informative if they incorporate well-formulated hypotheses built on a sound foundation of basic mechanistic and pharmacologic understanding. The first step in clinical trials of natural products is to demonstrate that the intervention exerts a measurable effect on a hypothesized “target” or mechanism of action rather than just focusing on demonstrating a change in clinical symptom(s). “Target engagement” refers to verification that the intervention has had the predicted effect on the target. Targets may be molecular, cellular, circuit, biological, tissue, organ, somatic, psychological, behavioral, or interpersonal. Following the initial demonstration of target engagement, the next step of novel intervention development involves replicating target engagement and evaluating whether intervention-induced changes in the target are associated with clinical benefit. In some cases, a fundamental understanding of a given natural product’s biologic target or mechanism of action has been clearly established (e.g., compound’s affinity for a specific receptor is well established). It is also recognized that for certain conditions (e.g., pain), demonstrating target engagement may not be possible or practical with human participants. When a mechanism of action has already clearly been established or when measuring target engagement is not possible, investigators should contact a member of the program staff at NCCIH to discuss what funding mechanism is appropriate. 

There is a need for research to evaluate natural products to determine whether they are safe and efficacious or effective for given conditions or disorders. To accomplish this goal, mid-phase clinical trials conducted through the R01 are important to determine optimal dosing of and participant characteristics for the natural product’s use prior to conducting a fully powered clinical trial.

Overview of NCCIH Natural Products Clinical Trials Research Funding Opportunities 

NCCIH has designed a framework for research to describe the broad spectrum of complementary and integrative health research it supports (https://www.nccih.nih.gov/grants/nccih-clinical-trials-funding-opportunities/research-framework). NCCIH supports investigators working on the continuum of the research framework, from basic science and demonstrating reproducible impact on a target engagement measure through high impact efficacy trials (https://www.nccih.nih.gov/grants/nccih-clinical-trials-funding-opportunities/natural-products-clinical-trials-funding-opportunities). We encourage investigators to examine the full suite of natural product research NOFOs to determine which one best aligns with the proposed stage of intervention development and testing.

NCCIH has an oversight process to provide stewardship and maintain excellence, integrity, and rigor in our supported clinical studies (https://www.nccih.nih.gov/grants/toolbox). Investigators are encouraged to review the NCCIH Clinical Terms of Award for Human Subjects Research (https://www.nccih.nih.gov/research/nccih-clinical-terms-of-award-for-human-subjects-research) to learn more about NCCIH’s requirements for clinical research.   

Prior to submitting an application, NCCIH strongly encourages consultation with the NCCIH Scientific/Research contacts relevant to the area of science for which they are planning to develop an application. Early contact provides an opportunity for NCCIH staff to discuss the scope and goals, and to provide information and guidance.

Purpose of the Mid-Phase Clinical Trial Award (R01)

The objective of this NOFO is to support clinical trials to increase the evidence base for a natural product. The following are examples of types of mid-phase clinical trials appropriate for this NOFO.

  • Dosing and formulation optimization of the natural product to evaluate the impact on the target engagement measure(s) to be used in a future multi-site, randomized clinical trial
  • Determining which patient phenotypes will be likely “responders” versus “non-responders” to the natural product to inform inclusion/exclusion criteria of a future efficacy trial
  • In addition, investigators can also collect additional data documenting ability to recruit, accrue, and retain participants; achieve adherence to the study protocol; and complete collection of follow-up data

Subsequent Studies 
The objective of this NCCIH R01 mid-phase clinical trial NOFO is to gain additional knowledge about a natural product in order to plan and conduct a future multi-site, randomized clinical trial. Investigators are encouraged to include relevant stakeholders (e.g., patients, providers, health care systems, etc.) in the planning and execution of exploratory and larger clinical trials. Several outcomes from a grant awarded under this NOFO are possible: (1) the product does not warrant further study for the particular target, condition, or disorder of interest; (2) additional studies must be completed before proceeding to a full-scale multi-site efficacy trial; or (3) the data generated under this award are informative and sufficient to warrant moving ahead with a well-executed multi-site efficacy clinical trial. If warranted by the results of studies conducted, awardees may prepare and submit an application for a subsequent clinical trial when the R01 trial is complete and results have been analyzed. Prospective applicants should note that funding of a trial under this NOFO does not guarantee that NCCIH will accept, or fund, a subsequent multi-site clinical efficacy trial application. 
 

Design Considerations

Investigators should propose a randomized controlled trial design with at least one intervention arm and one comparator arm. There should be a strong rationale for the comparator condition (e.g., time and attention control, usual care, standard of care, placebo, and/or active comparator(s)) based on the research question you plan to address in the future powered trial. Due to lack of rigor and potential expectancy effects, NCCIH will not support studies proposing a waitlist comparator condition.

Power Recommendations:

This R01 is a mid-phase clinical trial that is meant to support research activities that will inform future large-scale efficacy or effectiveness trials. Studies supported by this NOFO should be adequately powered to test a hypothesis/hypotheses related to the natural product dose, participant phenotype, or study process metrics identified as being essential to inform a future fully powered efficacy or effectiveness trial. The sample sizes that can be supported under this NOFO are limited; therefore, proposing to conduct fully powered tests of clinical outcomes (i.e., efficacy) or underpowered tests of outcomes (i.e., “preliminary efficacy”), or attempting to utilize the highly variable point estimate of an effect size for power calculations would not be appropriate and are noted as nonresponsive below. 

Regulatory Requirements To Consider:

The U.S. Food and Drug Administration (FDA) establishes and enforces the regulatory requirements for clinical research on natural products when they may be 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 Study Record: PHS Human Subjects and Clinical Trials Information description of the availability of Investigational Product (IP) and IND/Investigational Device Exemption (IDE) status. 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 

For applications that propose the use of a mobile device, similar app, or clinical decision support software, applicants must consult with their Institutional Review Board (IRB) to determine whether the approach may qualify as a medical device. If so, applicants must contact the FDA prior to applying to determine whether an IDE application is necessary for the proposed clinical research (https://www.fda.gov/medical-devices/software-medical-device-samd/your-clinical-decision-support-software-it-medical-device). 

Preliminary data requirements

This NOFO is appropriate when there is a compelling rationale, a rigorous empirical basis, and scientific premise, which should include preliminary data from animal studies and previously published and citable human studies.

The following preliminary data from human studies (published and citable data from the peer-reviewed literature) on the same product and specific formulation as proposed in the current application will provide a strong justification for the proposed work:

  1. Demonstration that the natural product can produce a clinically meaningful change in measurable target engagement (e.g., mechanism of action) in the human population of interest. There must also be evidence that the change in target engagement has been replicated in a separate human study with the same natural product to be used in the proposed project, unless it is impossible or impractical to do so or when a mechanism of action has been clearly established.
  2. Evidence that evaluates the pilot study data for strength of correlation between the impact on target engagement and changes in the clinical outcome that will be studied in the proposed clinical trial (unless waived by condition below).
  3. Evidence that the specific natural product is bioavailable in humans. Note that for prebiotics or probiotics this may be demonstrated by documenting short-term retention in the gastrointestinal tract.
  4. Evidence that the natural product does not produce frequent or severe adverse events in human pilot trials.

For the purposes of this NOFO, it is preferred that there be an established, measurable, reproducible, well-characterized target engagement measure for a given natural product in human subjects. However, NCCIH acknowledges that for some conditions, it may be impossible or impractical to directly measure the target engagement of a natural product. In these circumstances the study should be justified by: (1) a clear rationale for why studying a target engagement measure in human participants is impossible or impractical; (2) potentially proposing other objective, reproducible measures that may be proxy to or indicative of target engagement for the natural product; and (3) strong compelling preliminary data to warrant further study of the natural product in clinical studies. In other cases, a fundamental understanding of a given natural product’s biologic target or mechanism of action has been clearly established (e.g., compound’s affinity for a specific receptor is well established). In these situations, investigators are encouraged to contact NCCIH Scientific/Research staff to determine whether the R01 is the appropriate NOFO for the proposed clinical trial. 

For applications that include a mind and body approach as part of a multi-component intervention, the application must provide published data that the mind and body intervention proposed has demonstrated efficacy for the condition being studied from at least one fully powered controlled trial.

Timeline

For this NOFO, investigators should design a realistic timeline for the startup and completion of the clinical trial and provide contingency plans to proactively confront potential delays or disturbances to the planned trial.

NCCIH Priorities for Developing and Pilot-Testing Natural Products 
As NCCIH’s clinical research portfolio matures, NCCIH has identified targeted areas of investigation to align with the NCCIH Strategic Plan (https://www.nccih.nih.gov/about/strategic-plans-and-reports). The focus is on management of conditions for which natural products are used by the public and where there is evidence of a postulated mechanism of action. For this NOFO, NCCIH considers the following topic areas to have high program priority: 

  • Symptom management, particularly the use of natural products for sleep disorder/disturbance, management of pain conditions, common gastrointestinal disorders, post-acute sequelae of SARS-CoV-2 infection (PASC), or mental health conditions such as those commonly managed in primary care (e.g., chronic stress, depression, anxiety disorders, and post-traumatic stress). 
  • Studies that examine the effects of prebiotics/probiotics and other natural products on gut microbiome-brain interactions. Of particular interest are studies of prebiotics/probiotics for depression, anxiety disorders, irritable bowel syndrome (IBS), or chronic pain. 
  • Studies that examine the effects of cannabinoids and terpenes in conditions noted above. 
  • Studies that examine the effects of naturally occurring psychedelics and entheogens in conditions noted above. 
  • Studies that address minority health and reduce disparities in conditions noted above. 
  • Studies that examine the effects of natural products to address comorbidities, coinfections, and/or complications from HIV (https://www.oar.nih.gov/hiv-policy-and-research/strategic-plan). 
  • Trials that examine the effects of natural products across the continuum of background dietary intake.
  • Trials that evaluate whether nutritional status moderates target engagement or clinical outcomes.

All NIH-funded research must adhere to the Code of Federal Regulations, which outlines specific requirements to enhance protections for pregnant women, human fetuses, and neonates; children; and prisoners (https://grants.nih.gov/policy/humansubjects/policies-and-regulations/vulnerable-populations.htm). The Inclusion Across the Lifespan policy requires that individuals of all ages, including children (i.e., individuals under the age of 18) and older adults, must be included in all human subjects research conducted or supported by NIH, unless there are scientific or ethical reasons not to include them (https://grants.nih.gov/grants/guide/notice-files/NOT-OD-18-116.html).    

served rural populations, and people with disabilities. 

Applications proposing research topics not identified above as high programmatic priority can be submitted but are likely to be considered of lesser or low programmatic priority, which will significantly influence programmatic relevance and reduce the likelihood of funding. Applications proposing research studies using an intervention and patient population that are the same as or very similar to those used in studies already in progress, conducted, or published by other groups are likely to be of lower programmatic priority. Applications that do not address dietary intake and nutritional status when appropriate will also be deprioritized.

Clinical Trials Not Responsive to This NOFO

The following types of clinical trials are not responsive to this NOFO, and applications proposing such activities will be deemed nonresponsive and will not be reviewed:

  • Phase I/first in human trials.
  • Studies proposing to analyze data from the trial to assess efficacy of the natural product or estimate effect size (https://www.nccih.nih.gov/grants/pilot-studies-common-uses-and-misuses).
  • Trials proposing to measure or replicate the effect of a natural product through target engagement. 
  • Animal studies.
  • Trials that do not include a natural product or standardized nutritional regimen.
  • Studies utilizing a natural compound that has been synthetically modified (e.g., conjugates, derivatives, or pro-drugs).
  • Studies that propose a waitlist control.
  • Trials that propose to test natural products for the treatment or prevention of cancer. (Investigators interested in cancer treatment or prevention trials should contact the National Cancer Institute.)

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 materials.

Investigators proposing NIH-defined clinical trials may refer to the Research Methods Resources website for information about developing statistical methods and study designs.

Research Strategy

Note: Discuss the overall approach but do not duplicate information collected in the PHS Human Subjects and Clinical Trials Information Form.

The Research Strategy should be organized in a manner that will facilitate peer review. The body of the application must present an overview of the state of the science, current status and relevance of the trial, a discussion of the specific protocol, and the approach to data collection, analysis, and dissemination.

The following criteria must be addressed:

Importance of Research: The significance and innovation of the proposed clinical trial and importance of the question must be clearly stated. The application should provide rigorous preclinical or clinical preliminary data to support the study rationale. The application should make clear the need for and timeliness of the study with emphasis on how the results will address an evidence gap and therefore advance our knowledge of theory and practice in this area. The application should describe how the proposed project will advance knowledge to determine if the natural product can reproducibly modify target engagement so that future clinical trials can determine if the target is a mediator of clinical benefit. It is particularly important that there be discussion of how the results of the proposed trial (positive or negative) will guide decisions about whether a subsequent study is needed or justified, and/or provide evidence that additional studies must be completed before proceeding to a full-scale multi-site efficacy trial. A discussion of the costs and benefits of the study should be included for evaluation of the trial’s significance. The applicant is expected to provide a precise response to the following two questions: 1) Will the result, whether positive or negative, be informative and provide a definitive test of the hypothesis? 2) Will the results be informative about the potential role of target engagement in the clinical condition? .

Explain how the application challenges and seeks to shift current research or clinical practice paradigms or guidelines.

Rigor and Feasibility: The research approach section should include a description of the supporting data (including strengths and weaknesses of the published literature), clinical trial experience, the experimental approach, and a timeline for completing the trial.

Supporting Data: The studies that led to the proposed clinical trial should be presented. Data from pilot studies that show the need for and the feasibility of the trial should also be presented in the application. Additional supporting data from other research should be included so that the approach chosen is clearly justified and adequately framed. Applications must include the following preliminary data from human studies (preferably published in the peer-reviewed literature):

  1. Demonstration that the natural product can produce a clinically meaningful change in measurable target engagement (e.g., mechanism of action) in the human population of interest. There must also be evidence that the change in target engagement has been replicated in a separate human study with the same natural product to be used in the proposed project, unless it is impossible or impractical to do so or when a mechanism of action has been clearly established.
  2. Evidence that evaluates the pilot study data for strength of correlation between the impact on target engagement and changes in the clinical outcome that will be studied in the proposed clinical trial (unless waived by condition below).
  3. Evidence that the specific natural product is bioavailable in humans. Note that for prebiotics or probiotics this may be demonstrated by documenting short-term retention in the gastrointestinal tract.
  4. Evidence that the natural product does not produce frequent or severe adverse events in human pilot trials or justification for why studying target engagement in human participants is impossible or impractical;

If it is impractical/impossible to measure the impact of the natural product on target engagement or when there is a fundamental understanding of the product’s mechanism of action, such that it is not possible to provide items 1 and 2, applicants must provide the following:

  • Consider proposing other objective, reproducible measures that may be proxy to or indicative of target engagement for the natural product.
  • Provide strong compelling preliminary data to warrant further study of the natural product in clinical studies. 

Experimental Approach: The proposed experimental approach should include an appropriate study design and the rationale for the particular design chosen. The experimental approach description should include:

  • A description and rationale for the research hypothesis(es), methods of randomization if applicable, primary and secondary outcome measures, intervention(s), measurement of the replicable target engagement measure(s) of the natural product, and participant follow-up procedures.
  • A rationale, including supporting data for the natural product to be tested, including: name and ingredients of the product, rationale for the supplier, proposed methods for product characterization and standardization, and rationale for selection of and specified percentages or levels of marker compounds, if applicable. See the NCCIH Policy on Natural Product Integrity for more information (https://NCCIH.nih.gov/research/policies/naturalproduct.htm).
  • All necessary agreements for the use of the natural product in the study, including clinical research agreements and licensing agreements, must be executed prior to grant award. A timeline should be included in the application showing activities with third parties such as 1) executing necessary agreements, 2) providing natural product and matching placebo, and 3) permission to reference an open IND drug master file (if available).
  • Engagement of the clinical community that is playing a critical role in the recruitment, retention, and overall conduct of the clinical trial including the prioritization of this clinical trial in the context of other overlapping clinical research. Description of this commitment should be provided.
  • A description and justification for all assessments including clinical, laboratory, physiological, behavioral, patient-centered, or other outcomes addressing the primary and secondary research questions. Use of patient-reported outcomes as well as non-traditional data collection approaches (e.g., telephone, mobile devices, or web-based systems) needs to be described. A description of the laboratory evaluations (as appropriate) and plans to implement and monitor Good Clinical Practices (GCP), Good Laboratory Practices (GLP), and Good Manufacturing Practices (GMP), as appropriate should be provided.
  • A description of the approach to obtain regulatory approvals.
  • A description of the clinical equipoise. 
  • A discussion of potential challenges in implementing the research protocol and how they will be addressed.

Letters of Support

Letters of support from clinicians or clinical department chairs whose support is necessary to the successful conduct of the trial should be provided. Applicants are also encouraged to include documentation of the commitment of any subcontractors and consultants, as well as service agreements for personnel or facilities. Letters of commitment must be cosigned by the business official of the collaborating center. In addition, a letter of support should document that sufficient supply of the natural product will be available for testing at the time of award, including expiration date; that the supplier will meet and provide details regarding Chemistry Manufacturing and Controls specifications; and that the supplier will provide the data necessary for the investigator to adhere to NIH and FDA policies. Documentation should include a letter of agreement from the third party supplying the natural product.

Investigators are encouraged to review the NCCIH Study Accrual and Retention Plan (https://www.nccih.nih.gov/grants/policies/nccih-policy-study-accrual-and-retention-for-human-subject-research).

Additionally, please include a description of the study population and why it is the most appropriate group to answer the question, and how or if results will generalize to a broader population.

2.7 Study Timeline

Milestone Plan: The milestone plan should describe the key milestones that need to be met throughout the lifecycle of the clinical trial to ensure its success, the processes that will be used to reach the milestones, and a timetable identifying when each of these key milestones will be met.

All applicants must use the following definition of a milestone in their application: a scheduled event in the project timeline that signifies the completion of a major project stage or activity. Milestones must be relevant, achievable, and measurable. The research plan should include anticipated challenges to meeting milestones and propose potential mitigation or corrective actions strategies. Milestones should address overall recruitment and retention goals.

Milestones of particular interest that should be described in the application may include, but are not limited to, the following:

  • Complete finalized clinical protocol approved by NCCIH and Protocol Review Committee/Data and Safety Monitoring Board (DSMB) (if required)
  • Final informed consent(s) and, if applicable, assent forms (if required)
  • Agreements in place for product supply
  • Comprehensive laboratory plan
  • Pharmacy/Laboratories Identification (as applicable)
  • Contracts/Third Party Agreements (if applicable)
  • Training plan for clinical site(s)
  • Final Data and Safety Monitoring Plan approved by NCCIH
  • Submission of an approved Study Accrual and Retention Plan by the Authorized Business Official prior to the clinical trial
  • Data Completeness and Quality Monitoring Reporting Plan
  • Completion of regulatory approvals
  • Single Institutional Reivew Board (sIRB) approval for clinical sites
  • Target dates for percent enrollment of 10, 25, 50, 75, and 100 percent of the projected recruitment for all study subjects, including women, minorities, and children (as appropriate)
  • Assessment of site(s) protocol implementation performance
  • Collection of data related to primary and secondary endpoints and database lock
  • Submission of primary manuscript to peer-reviewed scientific journal
  • Submission of study results to ClinicalTrials.gov within 12 months of the primary completion date

During the award phase, achievement of each milestone will need to be communicated to the NCCIH program officer listed on the Notice of Award. Award continuation, even during the period recommended for support, is conditional upon satisfactory progress. If, at any time, recruitment, as defined in the NCCIH Accrual of Human Subjects (Milestones) Policy, falls significantly below projections, or core milestones mutually agreed upon by the PD/PI and NCCIH are not met, the NCCIH may consider ending support and negotiating an orderly phase-out of the award. NCCIH retains, as an option, periodic external peer review of progress. NCCIH staff will closely monitor progress at all trial stages including milestones, accrual, and safety.

Section 3 - Protection and Monitoring Plans

3.3 Data and Safety Monitoring Plan

In addition to the NIH application requirements for data and safety monitoring for clinical trials, NCCIH requires independent monitoring for research involving human subjects. Applicants should refer to NIH’s policy on data and safety monitoring (https://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-038.html), as well as the NCCIH guidelines for data and safety monitoring (https://nccih.nih.gov/grants/policies/data-safety-monitoring). The Independent Monitoring Committee (IMC) or DSMB will have the responsibility to review interim and final data and recommend whether the protocol should be modified, and, at each meeting, whether the study should be continued or should be terminated early. Thus, its ethical responsibilities, to the participants as well as to the integrity of the study, are of paramount importance to NCCIH. The IMC/DSMB should meet in person or by phone at least twice a year. Applicants should not appoint IMC/DSMB members in advance of the peer review, or even inquire about the interest of possible DSMB members, because anyone so contacted would not be eligible to serve as a member of the peer review committee that will evaluate the applications for scientific merit.

Section 4 - Protocol Synopsis

4.5. Will the study use an FDA-regulated intervention?

4.5.a. If yes, describe the availability of Investigational Product (IP) and Investigational New Drug (IND)/Investigational Device Exemption (IDE) status:

The proposed clinical trial must use a natural product (such as botanicals, probiotics, and products marketed as dietary supplementl) for this NOFO. The attachment in this section should describe correspondence from the FDA indicating whether the proposed study will require an IND/IDE or not.  Investigators should describe the process that will be used for attaining all necessary FDA or other applicable regulatory agency approvals necessary to the conduct of the trial, and an associated timeline to complete these approvals. For trials using an FDA-regulated product that require an IND/IDE application, the grant application must include evidence regarding the outcome of a pre-IND meeting, or other evidence of communication with the FDA. If the protocol is conducted under a non-U.S. regulatory agency, the applicant should submit a plan for attaining those regulatory approvals. If the protocol is exempt from an IND/IDE, a copy of the exemption letter from the FDA should be provided. The FDA has provided guidance indicating that when substances that are Generally Recognized as Safe (GRAS) are used in a clinical trial to evaluate the product’s ability to diagnose, cure, mitigate, treat, or prevent disease it may require an IND under part 312 (https://www.fda.gov/media/79386/download). If an IND is required by the FDA for the proposed R01 trial(s), the IND must be submitted to the FDA with no clinical hold imposed by the FDA prior to the application being funded. .

2. Review and Selection Process

Applications will be evaluated for scientific and technical merit by (an) appropriate Scientific Review Group(s) convened by NCCIH, 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 PHS referral guidelines to the appropriate NIH Institute or Center. Applications will compete for available funds with all other recommended applications submitted in response to this NOFO. 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, consistent with applicable law.

  • 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:

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

Successful recipients under this NOFO agree that:

Where the award funding involves implementing, acquiring, or upgrading health IT for activities by any funded entity, recipients and subrecipient(s) are required to: Use health IT that meets standards and implementation specifications adopted in 45 CFR part 170, Subpart B, if such standards and implementation specifications can support the activity.  Visit https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-D/part-170/subpart-B to learn more.

Where the award funding involves implementing, acquiring, or upgrading health IT for activities by eligible clinicians in ambulatory settings, or hospitals, eligible under Sections 4101, 4102, and 4201 of the HITECH Act, use health IT certified under the ONC Health IT Certification Program if certified technology can support the activity. Visit https://www.healthit.gov/topic/certification-ehrs/certification-health-it to learn more.

Pursuant to the Cybersecurity Act of 2015, Div. N, § 405, Pub. Law 114-113, 6 USC § 1533(d), the HHS Secretary has established a common set of voluntary, consensus-based, and industry-led guidelines, best practices, methodologies, procedures, and processes.
