Funding Opportunity Purpose

This notice of funding opportunity (NOFO) provides funding to conduct efficacy studies in an established rare disease preclinical model to demonstrate that a proposed therapeutic agent warrants further development. In addition to preclinical efficacy, accompanying pharmacodynamic and pharmacokinetic studies would be supported. Therapeutic agents include small molecules, biologics or biotechnology-derived products. The goal of this NOFO is to spur therapeutic development for a variety of rare diseases by advancing projects to the point where they would attract subsequent investment supporting full Investigational New Drug (IND) application development or progression to clinical trials in the case of repurposing or repositioning.

Section I. Notice of Funding Opportunity Description

Background and Funding Purpose

The NIH supports research on a broad range of diseases that are defined as rare; that is, diseases affecting fewer than 200,000 individuals in the United States. While individually, each rare disease affects a limited number of individuals, when viewed collectively, rare diseases represent a significant unmet medical need. Approximately 30 million people in the United States are living with one of the estimated 10,000 rare diseases; many of which affect children and are serious or life-threatening. Despite advances in our understanding of the mechanisms of many rare diseases, and large investments by pharmaceutical and biotech industries, effective treatments are available for fewer than 5% of diseases. This dearth is a result of myriad interconnected factors including: 1) low disease prevalence resulting in fewer patients, clinicians, researchers; 2) fewer resources given a smaller market size; 3) high developmental failure rates resulting from a lack of high-quality preclinical data in disease-specific models.

Further, the transition from early drug discovery efforts (assay development, high-throughput screening, counter/orthogonal screening, medicinal optimization) to full IND-enabling work is hampered by a lack of funding to support high-quality efficacy testing. These pharmacology studies are expensive, particularly when the studies are designed for rigorous evaluation that would support progression to an IND-enabling enterprise. This results in significant delays in development of potential therapeutics and leaves projects without a path forward. In order to address these issues, the National Center for Advancing Translational Sciences (NCATS) invites applications aiming to develop or repurpose therapeutics to treat a rare disease with an unmet medical need. It is the intent of this opportunity to fund a diverse set of applications focused on a variety of rare disease indications.

Research Objectives and Scope

This notice of funding opportunity (NOFO) solicits applications that propose to conduct efficacy studies in an established rare disease preclinical model to demonstrate proof of concept that a proposed therapeutic agent warrants further development. In addition to preclinical efficacy, accompanying pharmacodynamic (PD) and pharmacokinetic (PK) studies would be supported. In preclinical efficacy studies, a combination of efficacy, (PD) and (PK) measures are warranted to determine the feasibility of a candidate therapeutic agent to serve as a starting point for further therapy development. Combined measures of PK and PD greatly increase the understanding of the in vivo efficacy of the therapeutic agent by exploring the relationship between the concentration of the agent at the site of action and the resulting efficacy measures.

For the purposes of this NOFO, efficacy measures reflect the effects of the therapeutic agent on endpoints that are closely tied to the desired clinical endpoints, but do not necessarily reflect target engagement. While PD measures may also reflect the effects of the therapeutic agent on endpoints closely tied to the desired clinical endpoint, they must also reflect target engagement. PK measurements reflect the body’s effect on the absorption, metabolism, distribution and excretion of the therapeutic agent. While not required, PK to provide evidence that the therapeutic agent has the potential to be therapeutically viable and support the robustness of the efficacy data, is encouraged, if the limited R21 budget can accommodate such studies.

Efficacy studies should be conducted in an established and validated rare disease model. These models may include both in vivo models and/or in advanced in vitro models (e.g. tissue chip/microphysiologic systems). Data supporting relevance and validation of the model to the indicated rare disease should be included in the application. Funding will not be provided for model development; evidence supporting access to the model, in suitable numbers to support rigorous efficacy studies, must be provided.  A letter of support if the animals will be provided by a collaborator, or a quote for purchase must be included in the Letters of Support attachment.    

To ensure both the relevance of the proposed development of the therapeutic agent, as well as the disease model, a plan for a partnership with a rare disease steering/oversight committee is required to submit to this NOFO. However, neither the members of the committee nor the organizations that might partner should be named in the application This committee may be formed de novo with members having appropriate disease relevant expertise and/or experience and could include a potential financial backer. The plan should include only a description of the type of individuals (expertise, patients and/or advocates, foundation representatives – do NOT name the foundation, etc.) and the planned interactions with the scientific team will need to be clearly described as an Other Attachment as part of the application.  

Further, developing therapeutics requires a multidisciplinary approach. It is encouraged that academic investigators should form collaborations with those knowledgeable in the therapeutic development process, as well as those familiar with the desired properties of the end therapeutic product (such as biostatisticians, technical experts and clinicians). Applicants should consider how they will identify and foster relationships with potential licensing and commercialization partners early in the therapy development process once an award is made. Investigators are expected to work closely with their institutional technology transfer officials, if applicable, to ensure that royalty agreements, patent filings, and all other necessary intellectual property (IP) arrangements are completed in a timely manner and that commercialization plans are developed and updated over the course of the project. 

Applications Not Responsive to this NOFO

The following types of studies are not responsive to this NOFO. Applications proposing such studies will be considered non-responsive and will not be reviewed or considered for funding.

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:
 

The R21 exploratory/developmental grant supports investigation of novel scientific ideas or new model systems, tools, or technologies that have the potential for significant impact on biomedical or biobehavioral research. An R21 grant application need not have extensive background material or preliminary information. Accordingly, reviewers will emphasize the conceptual framework, the level of innovation, and the potential to significantly advance our knowledge or understanding. Appropriate justification for the proposed work can be provided through literature citations, data from other sources, or, when available, from investigator-generated data. Preliminary data are not required for R21 applications; however, they may be included if available.

Overall Impact

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).

Scored Review Criteria

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.

 

Does the project address an important problem or a critical barrier to progress in the field? Is the prior research that serves as the key support for the proposed project rigorous? If the aims of the project are achieved, how will scientific knowledge, technical capability, and/or clinical practice be improved? How will successful completion of the aims change the concepts, methods, technologies, treatments, services, or preventative interventions that drive this field?

Specific to this NOFO:

  • How strong is the evidence in the application that the disease or condition meets the criteria of being rare (fewer than 200,000 patients in the U.S. and/or documentation of FDA orphan status)?
  • How strong is the rationale there is an urgent unmet need for the specific rare disease?
  • To what extent does the application show an understanding of the state of the field and where the proposed therapeutic approach addresses a gap within the therapeutic landscape?
  • How strong is the evidence that proposed model is relevant to the rare disease?
  • How strong is the evidence validating the model for the particular rare disease?
  • How clear is the biological rationale linking the proposed therapeutic target and the rare disease of interest?
  • To what extent are the therapeutic agents ready to be tested for efficacy in vivo or in an advanced in vitro system? 
 

Are the PD(s)/PI(s), collaborators, and other researchers well suited to the project? If Early Stage Investigators or those in the early stages of independent careers, do they have appropriate experience and training? If established, have they demonstrated an ongoing record of accomplishments that have advanced their field(s)? If the project is collaborative or multi-PD/PI, do the investigators have complementary and integrated expertise; are their leadership approach, governance, and organizational structure appropriate for the project?

Specific to this NOFO:

  • To what extent is the investigator team knowledgeable and experienced with the proposed biological target?
  • To what extent do the researchers demonstrate sufficient understanding of the experimental design concepts, including rigor and reproducibility, necessary for successful translation of preclinical and therapeutic discovery research?
  • To what extent does the investigative team have knowledge and experience of the rare disease? 
 

Does the application challenge and seek to shift current research or clinical practice paradigms by utilizing novel theoretical concepts, approaches or methodologies, instrumentation, or interventions? Are the concepts, approaches or methodologies, instrumentation, or interventions novel to one field of research or novel in a broad sense? Is a refinement, improvement, or new application of theoretical concepts, approaches or methodologies, instrumentation, or interventions proposed?

Specific to this NOFO: 

While the approaches may not be innovative, how much will success bring the field closer to a therapeutic that will be either a substantial improvement over existing therapeutics or is distinct from other therapeutic approaches currently available for the rare disease being targeted? 

 

Are the overall strategy, methodology, and analyses well-reasoned and appropriate to accomplish the specific aims of the project? Have the investigators included plans to address weaknesses in the rigor of prior research that serves as the key support for the proposed project? Have the investigators presented strategies to ensure a robust and unbiased approach, as appropriate for the work proposed? Are potential problems, alternative strategies, and benchmarks for success presented? If the project is in the early stages of development, will the strategy establish feasibility and will particularly risky aspects be managed? Have the investigators presented adequate plans to address relevant biological variables, such as sex, for studies in vertebrate animals or human subjects? 

If the project involves human subjects and/or NIH-defined clinical research, are the plans to address 1) the protection of human subjects from research risks, and 2) inclusion (or exclusion) of individuals on the basis of sex/gender, race, and ethnicity, as well as the inclusion or exclusion of individuals of all ages (including children and older adults), justified in terms of the scientific goals and research strategy proposed?

Specific to this NOFO:

Additional Review Criteria

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.

 

For research that involves human subjects but does not involve one of the categories of research that are exempt under 45 CFR Part 46, the committee will evaluate the justification for involvement of human subjects and the proposed protections from research risk relating to their participation according to the following five review criteria: 1) risk to subjects, 2) adequacy of protection against risks, 3) potential benefits to the subjects and others, 4) importance of the knowledge to be gained, and 5) data and safety monitoring for clinical trials.

For research that involves human subjects and meets the criteria for one or more of the categories of research that are exempt under 45 CFR Part 46, the committee will evaluate: 1) the justification for the exemption, 2) human subjects involvement and characteristics, and 3) sources of materials. For additional information on review of the Human Subjects section, please refer to the Guidelines for the Review of Human Subjects.

 

When the proposed project involves human subjects and/or NIH-defined clinical research, the committee will evaluate the proposed plans for the inclusion (or exclusion) of individuals on the basis of sex/gender, race, and ethnicity, as well as the inclusion (or exclusion) of individuals of all ages (including children and older adults) to determine if it is justified in terms of the scientific goals and research strategy proposed. For additional information on review of the Inclusion section, please refer to the Guidelines for the Review of Inclusion in Clinical Research.

 

The committee will evaluate the involvement of live vertebrate animals as part of the scientific assessment according to the following three points: (1) a complete description of all proposed procedures including the species, strains, ages, sex, and total numbers of animals to be used; (2) justifications that the species is appropriate for the proposed research and why the research goals cannot be accomplished using an alternative non-animal model; and (3) interventions including analgesia, anesthesia, sedation, palliative care, and humane endpoints that will be used to limit any unavoidable discomfort, distress, pain and injury in the conduct of scientifically valuable research. Methods of euthanasia and justification for selected methods, if NOT consistent with the AVMA Guidelines for the Euthanasia of Animals, is also required but is found in a separate section of the application. For additional information on review of the Vertebrate Animals Section, please refer to the Worksheet for Review of the Vertebrate Animals Section.

 

Reviewers will assess whether materials or procedures proposed are potentially hazardous to research personnel and/or the environment, and if needed, determine whether adequate protection is proposed.

 

For Resubmissions, the committee will evaluate the application as now presented, taking into consideration the responses to comments from the previous scientific review group and changes made to the project.

Reviewers will consider whether the budget and the requested period of support are fully justified and reasonable in relation to the proposed research.

2. Review and Selection Process

Applications will be evaluated for scientific and technical merit by (an) appropriate Scientific Review Group(s) convened by NCATS, in accordance with NIH peer review policy and procedures, 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.

Appeals of initial peer review will not be accepted for applications submitted in response to this NOFO.

Applications will be assigned 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 NCATS Advisory Council. The following will be considered in making funding decisions:

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

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

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. This request is not a Notice of Award nor should it be construed to be an indicator of possible funding. 

A formal notification in the form of a Notice of Award (NoA) will be provided to the applicant organization for successful applications. The NoA signed by the grants management officer is the authorizing document and will be sent via email to the recipient's business official.

Recipients must comply with any funding restrictions described in Section IV.6. Funding Restrictions. Selection of an application for award is not an authorization to begin performance. Any costs incurred before receipt of the NoA are at the recipient's risk. These costs may be reimbursed only to the extent considered allowable pre-award costs.

Any application awarded in response to this NOFO will be subject to terms and conditions found on the Award Conditions and Information for NIH Grants website.  This includes any recent legislation and policy applicable to awards that is highlighted on this website.

Institutional Review Board or Independent Ethics Committee Approval: Recipient institutions must ensure that 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.

2. Administrative and National Policy Requirements

All NIH grant and cooperative agreement awards include the NIH Grants Policy Statement as part of the NoA. 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, including of note, but not limited to:

If a recipient is successful and receives a Notice of Award, 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.

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.

In accordance with the statutory provisions contained in Section 872 of the Duncan Hunter National Defense Authorization Act of Fiscal Year 2009 (Public Law 110-417), NIH awards will be subject to System for Award Management (SAM.gov) requirements. SAM.gov requires Federal agencies to review and consider information about an applicant in the designated integrity and performance system (currently SAM.gov) prior to making an award. 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 addition to the information available in the responsibility/qualification records in SAM.gov, in making a judgement about the applicant’s integrity, business ethics, and record of performance under Federal awards when completing the review of risk posed by applicants as described in 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.

Cooperative Agreement Terms and Conditions of Award

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.

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. 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.

The Federal Funding Accountability and Transparency Act of 2006 as amended (FFATA), includes a requirement for recipients of Federal grants to report information about first-tier subawards and executive compensation under Federal assistance awards issued in FY2011 or later.  All recipients of applicable NIH grants and cooperative agreements are required to report to the Federal Subaward Reporting System (FSRS) available at www.fsrs.gov on all subawards over the threshold.  See the NIH Grants Policy Statement for additional information on this reporting requirement.

In accordance with the regulatory requirements provided at 2 CFR Part 200.113 and Appendix XII to 2 CFR Part 200, recipients that have currently active Federal grants, cooperative agreements, and procurement contracts from all Federal awarding agencies with a cumulative total value greater than $10,000,000 for any period of time during the period of performance of a Federal award, must report and maintain the currency of information reported in the System for Award Management (SAM) about civil, criminal, and administrative proceedings in connection with the award or performance of a Federal award that reached final disposition within the most recent five-year period.  The recipient must also make semiannual disclosures regarding such proceedings. Proceedings information will be made publicly available in the designated integrity and performance system (Responsibility/Qualification in SAM.gov, formerly FAPIIS).  This is a statutory requirement under section 872 of Public Law 110-417, as amended (41 U.S.C. 2313).  As required by section 3010 of Public Law 111-212, all information posted in the designated integrity and performance system on or after April 15, 2011, except past performance reviews required for Federal procurement contracts, will be publicly available.  Full reporting requirements and procedures are found in Appendix XII to 2 CFR Part 200 – Award Term and Condition for Recipient Integrity and Performance Matters.
