Part 2. Full Text of Announcement

Section I. Funding Opportunity Description


According to the definition created by Congress in the Orphan Drug Act of 1983 and adopted by the FDA, a rare disease is a condition that affects fewer than 200,000 people in the United States. Ultra-rare diseases affect substantially fewer people, less than or equal to 6,000; in the U.S., this equates to as few or fewer than one in 50,000 people. Approximately 95% of rare diseases, including ultra-rare diseases, have no FDA-approved therapeutic available and an estimated 80% of rare diseases have an identified genetic origin. These rare diseases are often due to pathogenic variants in a single gene that alters gene product function. Many rare and ultra-rare diseases are caused by different pathogenic variants, some of which may be unique to a single individual or to a very small number of individuals. Cumulatively, these diseases represent a large unmet medical need as there are few available effective treatments and limited commercial incentive for therapeutic development.

The NINDS Ultra-Rare Gene-based Therapy (URGenT) network addresses challenges within ultra-rare disease communities by facilitating and supporting the development of tailored therapeutic interventions using established precision medicine platforms for the treatment of individuals diagnosed with a debilitating and often fatal, ultra-rare neurological and/or neuromuscular disease. Due to the urgency of these individuals conditions, rapid intervention in the clinical course of disease is critical. Therefore, the selection of a viable therapeutic approach will require the ability to customize the design, testing, and delivery of these interventions.

URGenT is poised to leverage nonclinical and manufacturing data from one project to another to enable the continuous reassessment of best development practices and clinical outcomes data. This would make a platform approach to therapeutic development more accessible to the ultra-rare disease communities and applicable to a broader range of diseases. In addition, this approach aims to facilitate harmonization of efforts when possible and bring therapeutic interventions to individuals more efficiently.

The design of early-phase clinical trials for gene-based therapies for individuals afflicted with ultra-rare disease often differs from the design of clinical trials for other types of therapies and relies upon unique collaborations to be successful. Successful completion of the activities in this X01 is expected to generate supporting data for further advancement of a proposed therapeutic towards clinical trials.


NINDS established the URGenT network to support the development, nonclinical, and clinical testing of gene-based or transcript-directed therapeutics for individuals with ultra-rare neurological disorders within the mission of NINDS. The overarching goal of URGenT is to rapidly advance precision therapeutics through manufacturing, nonclinical toxicology testing and other required IND-enabling activities, as well as evaluation in First-in-Human (FIH) clinical studies.

The purpose of this FOA is to provide investigators with a mechanism to access contract research/medical organizations (CROs/CMOs) and subject matter experts (SMEs) within the NINDS URGenT Network to support planning, manufacturing, and limited nonclinical therapeutic development. Contract access is in-kind and at no cost to the investigators.

Scope of the Program

URGenT provides multiple pathways into the network for studies that propose to utilize URGenT infrastructure and resources, culminating in submission of an IND package to the FDA and preparation for a subsequent application to conduct a FIH clinical trial. One path into the network is described in PAR-22-030 Translational Efforts to Advance Gene-based Therapies for Ultra-Rare Neurological and Neuromuscular Disorders (U01 - Clinical Trial Optional) and seeks applications proposing to conduct formal IND-enabling activities and clinical trial planning activities. Another path described in this FOA allows direct access to resources for applicants proposing to conduct planning activities and limited nonclinical development studies with a clinical candidate therapeutic to generate additional data (as needed) before a pre-Investigational New Drug (IND) meeting or submission of an IND application.

This Ultra-Rare Gene-based Therapy (URGenT) Network Resource Access (Clinical Trial Not Allowed) X01 encourages proposals from investigators for access to NINDS contract resources to assist in the planning, manufacturing, and nonclinical development activities that may be required before submitting an IND package to the FDA. Prior to requesting a pre-IND meeting with the FDA, the successful applicant will work with URGenT SMEs to determine what kind of feedback is needed and identify potential issues within existing or future research plans, protocols, or existing data. Only after potential issues are identified clearly can a plan to frame the discussion with the FDA be determined. This planning will lead to specific, focused questions for the FDA and help to identify considerations for future nonclinical and clinical therapeutic development activities.

Since a single ultra-rare disease may be caused by many different genetic variants, some of which may be unique to a very small numbers of individuals, the selection of a viable therapeutic approach will require the ability to customize the design, testing, and delivery of these interventions. The following gene-based and transcript-directed therapeutic modalities are potentially amenable to the development of precision gene-based or transcript-directed therapeutic approaches:

Oligonucleotide-based approaches
Oligonucleotides offer the potential to treat many genetic diseases by either ameliorating splicing pathogenic variants, promoting exon skipping, or targeting dominantly acting transcripts. Oligonucleotide-based interventions for neurological diseases include but are not limited to antisense oligonucleotides (ASOs), small interfering RNAs (siRNA) or short hairpin RNAs (shRNA).

Viral vector-based approaches
Viral-based therapeutics (e.g., Adeno-Associated Viruses (AAVs) and other potential vector and/or delivery vehicles, containing the correct gene construct, may be used as an in vivo therapeutic approach to replace or knockdown expression of a disease-causing gene. Alternatively, cell therapies involving ex vivo gene targeting may offer another therapeutic approach.

Genome editing-based approaches
Several platform technologies such as Zinc Finger Nucleases (ZFNs), Transcription Activator-like Effector-based Nucleases (TALENs) and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated protein systems have emerged as promising approaches to correct disease-causing pathogenic variants.

Other gene-based therapeutic approaches
Small-molecule drugs that can selectively bind RNA and modulate pre-mRNA splicing have potential as a treatment strategy for human genetic diseases. Therefore, these nucleic acid targeted small molecules have therapeutic potential in the treatment of some ultra-rare neurological and neuromuscular diseases.

Leveraging NINDS Contract Research Resources

URGenT will provide successful applicants access to therapeutic development resources, NINDS dedicated project management, and SME consultants. These NINDS contract resources will assist investigators to rapidly advance patient-customized therapeutics through manufacturing and nonclinical toxicology testing. A list of current URGenT resources can be found at

URGenT SME consultants will support successful applicants with strategic therapeutic development plans and assisting with preparation for a formal pre-IND meeting and/or submission of a pre-IND meeting package to the FDA. Once the investigator gathers characterization information, nonclinical data, and available clinical data, URGenT SME consultants can also assist with planning and preparation activities associated with the preparation of the IND package.

The SME consulting services may include support in disciplines such as:

  • Biologics Chemistry, Manufacturing and Controls (CMC)
  • Nonclinical/Preclinical, including Pharmacokinetics (PK), Pharmacodynamics (PD), and Toxicology
  • Bioassay Development
  • Biologics Regulatory Affairs and Regulatory Operations
  • Medical Writing
  • Biostatistics
  • Quality Assurance

URGenT nonclinical CROs/CMOs can support successful applicants by providing manufacturing, GLP toxicology, and other limited nonclinical resources for IND package submission.

The nonclinical CRO/CMO contract resources may include support in areas such as:

  • Technology-transfer, small-scale GLP lot or cGMP clinical lot manufacturing
  • GLP toxicology studies, PK/PD studies, ADME studies
  • Qualification/validation of bioassays for use in nonclinical or clinical studies

Entry Requirements

Proposals that have rational proof of concept (POC) data obtained through scientifically rigorous experimentation for a viable gene-based or transcript-directed therapeutic clinical candidate for a specified ultra-rare disease patient population that supports nonclinical and clinical development are encouraged to apply.

  • Patient or patient population has been identified with an ultra-rare neurological or neuromuscular syndrome due to a defined pathogenic variant.
  • A sufficient understanding of the pathogenic variant exists and is the basis of the proposed therapeutic approach that will allow for a plausible intervention strategy in the specified patient population.
  • The POC data establishes the feasibility and rationale for the use of the investigational candidate as evidenced by a pharmacologically effective dose range using appropriate assays.
  • The Program Director/Principal Investigator (PD/PI) has identified a gene-based or transcript-directed therapeutic clinical candidate supported by a substantial body of in vivo and/or in vitro data demonstrating that testing of the efficacy and preliminary safety of the candidate therapeutic in one or more model systems can mimic the planned clinical trial scenario.
  • The PD/PI intends to conduct a formal pre-IND meeting with FDA but needs to plan and/or generate limited additional data before preparing and submitting the pre-IND meeting data package.
  • The PD/PI intends to submit an IND package to the FDA but needs to address recommendations with planning and/or limited additional data resulting from the formal pre-IND meeting.

Access to URGenT Contract Resources

For each project provided access to the network, the NINDS will assemble a customized Multi-disciplinary Project Team (MPT). The MPT will include members of the PD/PI's team, additional SME consultants, and NIH staff. The MPT will establish an overall strategy for the project with milestones, including a plan and timeline, to develop and coordinate activities across different URGenT contract resources.

Each successful X01 applicant should expect to receive support for planning and/or implementation activities that will utilize the resources of and facilitate access to the contract resources of the NINDS URGenT Network.

The goal of the planning process is to develop a sufficiently detailed project development plan that will identify gaps and/or needs to support future regulatory interactions (e.g., pre-IND meetings and IND package). Implementation is expected to include activities to generate data or obtain information as identified before a pre-IND meeting is conducted and/or an IND package is submitted.

Applications to this X01 should be limited to activities that can be completed within 2 years.


Examples of planning activities that can be supported include, but are not limited to:

  • Formation of a MPT
  • Access to SMEs to assess feasibility and perform a gap-analysis of data and study requirements before a pre-IND meeting is conducted
  • Development of a product development plan, including Target Product Profile (TPP) and considerations for future nonclinical and clinical study requirements
  • Development of a regulatory strategy and establishment of objectives for a pre-IND meeting
  • Determination of scope and timeline of studies to be executed by NINDS URGenT CRO/CMO resources
  • Development of a regulatory strategy and establishment of objectives to prepare and submit a well-designed, well-executed IND package based on guidance received from FDA


Examples of implementation activities that can be supported include, but are not limited to:

  • Manufacturing - process development, engineering lot and/or GLP manufacturing
  • Confirmatory studies to demonstrate pharmacological activity and safety of the investigational clinical candidate
  • Additional studies (in vitro and/or in vivo) to support initial dosing estimates using the therapeutic clinical candidate
  • Bioassay development, e.g., potency assays, assays to measure the immune response to the therapeutic, etc., to be used to monitor safety and/or target engagement or biodistribution during clinical studies
  • Establishment of optimal route of delivery, timing of product administration, and/or dosing schedule(s)
  • Request and completion of a formal pre-IND meeting with the relevant division of the FDA
  • Preparation and submission of an IND package

Scope Limitations

Access to the resources available within the NINDS URGenT Network via an X01 is not intended to be a complete drug development program. Furthermore, obtaining access to SMEs and/or CROs/CMOs does not guarantee a successful therapy development plan nor imply a successful application for funding to other NIH programs.

Applications Not Responsive to this FOA

Applications that include any the following activities will be considered non-responsive and will not be reviewed:

  • Development of in vitro screening assays and/or animal models
  • Basic research of disease mechanisms or therapeutic mechanism of action studies
  • Lead optimization studies before selecting a clinical therapeutic candidate
  • Early stage discovery research, such as target identification and validation
  • Clinical research and clinical trials involving human subjects

Intellectual Property Rights and Confidentiality

This program is structured so that the awardee institution retains their assignment of IP rights and gains assignment of IP rights from the URGenT contractors (and thereby control the patent prosecution and licensing negotiations) for candidate therapeutics developed in this network. It is expected that the awardee institution will take responsibility for patent filings and maintenance and licensing efforts toward eventual commercialization. The PD/PI is expected to work closely with technology transfer/business development officials at his or her institution to ensure that royalty agreements, patent filings, and all other necessary IP arrangements are completed in a timely manner and that commercialization plans are developed and updated over the course of the project. Award recipients will be encouraged to identify and foster relationships with potential licensing and commercialization partners early in the drug development process, consistent with the goals of URGenT.

All SMEs will treat information as confidential and not disclose data or their assessments to third parties.

Section V. Application Review Information

1. Criteria

Only the review criteria described below will be considered in the review process.

For this particular announcement, note the following:

The X01 Resource Access Program invites eligible institutions to seek access to NIH research resources, which are specified in each X01 FOA. This includes programs where institutions will request access to submit to the resource (e.g., high throughput screening assays) as well as programs where access to a specific NIH research resource is needed to conduct certain research. Important factors in the peer review of X01 applications are the need for, and potential benefit of, gaining access to the resource, specifications for any assays proposed, timelines for completion and plans for follow-on studies.

  • Applications will be received and reviewed on a rolling basis. Applications will undergo a modified, two-step review process that will involve evaluation by NIH staff and individual external experts followed by peer review
  • The market size for the candidate therapeutic should not be considered in assessing the significance of a project.
  • Evaluation of the approach should focus on the clinical rationale, potential of the clinical candidate, potential patient benefit, competitive landscape (novelty), and strengths/weaknesses of activities/services requested by the PD/PI.
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).

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 this announcement, the following review criteria will be used:

  • Is the requested resource likely to lead to significant advances of the candidate towards IND submission and future clinical evaluation?
  • For a given well-reasoned and designed strategy, are the following included:
    • Milestones for success
    • Timeline
    • Objectives
    • A plan for future clinical studies
  • Is there sufficient reason to believe that use of the NINDS URGenT resources is appropriate for the proposed project?
  • How well does the project leverage resources of and ensure collaboration with the URGenT Network?
  • Are the proposal objectives stated clearly?
  • Is the timeline for developing, implementing, and completing the activities appropriate?
  • Does the application have a clear statement of the question(s) that the proposed work will address and its importance?
  • Does the application provide sufficient scientific rationale and clinical need for the requested resources?
  • Are the expertise and experience of the PD(s)/PI(s), collaborators, and other proposed researchers appropriate for the work they intend to conduct themselves with the therapeutic products or studies derived from use of NIH resources?
  • Has the applicant demonstrated sufficient and convincing evidence (i.e., supported by POC data from published literature and/or PI/PD-generated preliminary data) to support the proposed activities for the therapeutic candidate?
  • How rigorous were the experiments used to obtain the POC data? Are blinding, randomization, predetermined sample sizes, appropriate statistical analysis, SBV and authentication of reagents described?
  • Does the applicant have a sufficiently outlined plan to advance this proposal towards patient use? Does the plan include a discussion of the accessible and eligible patient population (i.e., the target candidates for treatment, the number of eligible patients with the genetic variant) and other feasibility considerations, including recruitment potential, follow-up requirements, and data quality?

Protections for Human Subjects

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 reviewers 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 reviewers 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.

Inclusion of Women, Minorities, and Individuals Across the Lifespan

When the proposed project involves human subjects and/or NIH-defined clinical research, the reviewers 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.

Vertebrate Animals

The reviewers will evaluate the involvement of live vertebrate animals as part of the scientific assessment according to the following criteria: (1) description of proposed procedures involving animals, including species, strains, ages, sex, and total number to be used; (2) justifications for the use of animals versus alternative models and for the appropriateness of the species proposed; (3) interventions to minimize discomfort, distress, pain and injury; and (4) justification for euthanasia method if NOT consistent with the AVMA Guidelines for the Euthanasia of Animals. Reviewers will assess the use of chimpanzees as they would any other application proposing the use of vertebrate animals. For additional information on review of the Vertebrate Animals section, please refer to the Worksheet for Review of the Vertebrate Animal 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 reviewers 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.

Not applicable.

Additional Review Considerations

Note: Effective for due dates on or after January 25, 2023, the Data Sharing Plan and Genomic Data Sharing Plan (GDS) as part of the Resource Sharing Plan will not be evaluated at time of review, and a Data Management and Sharing Plan is not applicable for this FOA.

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.

Applications from Foreign Organizations

Not Applicable.

Select Agent Research

Reviewers will assess the information provided in this section of the application, including 1) the Select Agent(s) to be used in the proposed research, 2) the registration status of all entities where Select Agent(s) will be used, 3) the procedures that will be used to monitor possession use and transfer of Select Agent(s), and 4) plans for appropriate biosafety, biocontainment, and security of the Select Agent(s).

Resource Sharing Plans

Reviewers will comment on whether the following Resource Sharing Plans, or the rationale for not sharing the following types of resources, are reasonable: (1) Data Sharing Plan; (2) Sharing Model Organisms; and (3) Genomic Data Sharing Plan (GDS).

Authentication of Key Biological and/or Chemical Resources:

For projects involving key biological and/or chemical resources, reviewers will comment on the brief plans proposed for identifying and ensuring the validity of those resources.

Budget and Period of Support

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

X01 applications will undergo a modified, two-step review process. The first step will involve the assessment of a project’s program fit and overall feasibility of accessing the resources. The second step will be peer review of the scientific and/or technical merit of applications. Reviewers will have expertise that spans multiple areas, such as pharmacokinetics, biological mechanisms, pharmaceutical industry development, gene-based therapy development, ultra-rare disease(s), and relevant scientific and clinical expertise. Access to consultants for planning stage projects that require input to devise future development plans may be made available to meritorious applications after the first review. These reviews are essential to ensuring selection of applications that best meet the requirements and mission of the program using established criteria (above) and to providing assurance to the public that the evaluation and selection process was impartial and fair. To achieve this result, NIH conducts reviews using standard practices that follow ethical standards applied to all extramural research. Conflicts of interest, prejudices, biases, or predispositions will be appropriately managed during the review process.

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

Applications will be assigned to NINDS. Following initial review, recommended applications may receive a second level of review by the National Advisory Neurological Diseases and Stroke (NANDS) Council. The following will be considered in making funding decisions:

  • Scientific and technical merit of the proposed project as determined by peer review.
  • Available capacity of the network at the time of review and impact of the requested study on resources available to support other projects.
  • 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 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.

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.

Awardees must comply with any funding restrictions described in Section IV.5. 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 FOA 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 awardee 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. More information is provided at Award Conditions and Information for NIH Grants.

Recipients of federal financial assistance (FFA) from HHS must administer their programs in compliance with federal civil rights laws that prohibit discrimination on the basis of race, color, national origin, disability, age and, in some circumstances, religion, conscience, and sex. This includes ensuring programs are accessible to persons with limited English proficiency. The HHS Office for Civil Rights provides guidance on complying with civil rights laws enforced by HHS. Please see and

HHS recognizes that 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 FOA.

Please contact the HHS Office for Civil Rights for more information about obligations and prohibitions under federal civil rights laws at or call 1-800-368-1019 or TDD 1-800-537-7697.

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 the Federal Awardee Performance and Integrity Information System (FAPIIS) requirements. FAPIIS requires Federal award making officials to review and consider information about an applicant in the designated integrity and performance system (currently FAPIIS) prior to making an award. An applicant, at its option, may review information in the designated integrity and performance systems accessible through FAPIIS and comment on any information about itself that a Federal agency previously entered and is currently in FAPIIS. The Federal awarding agency will consider any comments by the applicant, in addition to other information in FAPIIS, 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 45 CFR Part 75.205 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
