Grant Analysis

Purpose & Target

The core objective of this grant is to support the early-stage testing of pharmacologic or neuromodulatory device-based interventions for mental disorders. This involves using an 'experimental medicine approach' to rigorously validate molecular or circuit-based targets and evaluate their association with neurophysiological, behavioral, or clinical benefits. The grant is designed for research institutions, non-profits, for-profit organizations (including small businesses), and government entities capable of conducting complex clinical trials. It is a SECTOR-SPECIFIC grant, targeting the healthcare, mental health, pharmaceutical, and neuromodulation sectors. Geographically, it is open to organizations located in the United States and non-U.S. entities (foreign organizations). Key filtering criteria for initial screening: - Project must be an NIH-defined 'clinical trial'. - Focus on 'early-stage' intervention testing. - Must include 'objective measurement of molecular/circuit-based target engagement'. - Requires 'strong preliminary data' demonstrating target modulation. - Grant is a recurring opportunity with multiple submission deadlines, part of the R33 Exploratory/Developmental Phase II program.

Evaluation Criteria

Overall Impact
  • Reviewers will assess the likelihood of the project to exert a sustained, powerful influence on the research field involved, considering the scored review criteria below.
Scored Review Criteria
  • Factor 1. Importance of the Research (Significance and Innovation):
    • Significance: Description of the unmet therapeutic need and strong rationale for selecting the intervention and CNS target, supported by empirical evidence of its mechanism's involvement in improving symptoms or function in patients with mental illness.
    • Innovation: Proposal of a compelling rationale that the intervention is highly innovative (e.g., not already approved for psychiatric indication, not standard practice like SSRIs/ECT) and addresses an unmet therapeutic need, or has potential for substantially improving outcomes. Novelty of the proposed molecular/CNS target is also considered.
  • Factor 2. Rigor and Feasibility (Approach):
    • A compelling scientific rationale for the chosen protocol, including a clearly specified molecular/circuit-based target and its relationship to biomarkers/brain function/symptoms.
    • A clear conceptual framework with empirical support for the intervention and its mechanism of action leading to functional improvement.
    • Justification for the choice of clinical domain or measure of function in the patient population.
    • Assessment of planned co-enrollment for participants, addressing ethical implications, risks, burdens, benefits, and scientific validity.
    • Thorough description of preliminary data and its role in informing the proposed project, especially for dose/stimulus response relationships and target engagement.
    • Demonstration of a 'rigorous test of target engagement' with clear, concrete milestones (Go/No-Go Criteria of success) defined by quantitative threshold values.
    • Description of how the properly controlled, Good Clinical Practice (GCP) standard, validation study will be conducted (e.g., placebo-controlled, PK, safety, tolerability).
    • Evidence of sufficient data collection to determine molecular/CNS target validation based on relationships between target engagement, brain function measures, and clinical/functional effects.
    • Feasibility of the approach in terms of recruitment, data acquisition, and analysis within timely manner given shorter study timelines.
  • Factor 3. Expertise and Resources (Investigator(s) and Environment):
    • Combined expertise of the research team in clinical trials (pharmacologic/device-based), including experience with industry-funded trials, subject recruitment and retention, methodological and statistical expertise, and proficiency in all proposed measurement methods.
    • Evidence of a strong track record in successfully conducting early clinical trials (e.g., reporting in ClinicalTrials.gov, publications).
    • Description of the governance structure for conducting the study as proposed and within specified timelines.
Additional Review Criteria (Considered, not scored)

Compliance & Special Requirements

Regulatory and Ethical Compliance
  • Clinical Trial Requirement: This funding opportunity only accepts applications that propose NIH-defined clinical trial(s).
  • FDA Regulatory Oversight: Applications must demonstrate clear FDA regulatory oversight (e.g., Investigational New Drug (IND)/Investigational Device Exemption (IDE) status or Nonsignificant risk (NSR) determination) or provide a detailed plan and timeline for obtaining it before funding.
  • IRB/IEC Approval: All study protocols must be reviewed and approved by the applicant institution's Institutional Review Board (IRB) or Independent Ethics Committee (IEC).
  • Data and Safety Monitoring: A comprehensive 'Data and Safety Monitoring Plan' is required for all clinical trials to ensure participant safety and data integrity. This includes oversight by independent safety monitors or Data and Safety Monitoring Boards.
  • Human Subjects Protection: Detailed plans for the protection of research participants and consenting procedures for all participant groups are mandatory. Ethical implications and the risks, burdens, and benefits of co-enrollment (if applicable) must be addressed.
  • Nondiscrimination: Recipients must comply with all applicable nondiscrimination laws and submit an Assurance of Compliance (HHS-690).
  • Federal Regulations: All awards are subject to the terms and conditions outlined in the NIH Grants Policy Statement, 2 CFR Part 200 (Uniform Administrative Requirements), and relevant sections of the Public Health Service Act and Federal Regulations (42 CFR Part 52).
Data Management and Security
  • Data Management and Sharing Plan (DMSP): A DMSP is mandatory for all applications and must adhere to the 2023 NIH Policy for Data Management and Sharing. The plan must detail data types, formats, standards, access, preservation, and timelines.
  • National Institute of Mental Health Data Archive (NDA): Investigators funded under this NOFO are expected to share data via the NDA. This requires formulating an enrollment strategy to obtain information for generating a Global Unique Identifier (GUID) for each participant and a budget strategy to cover data submission costs. Data quality certification before submission is expected.
  • Cybersecurity: For recipients interacting with HHS systems or handling Personal Identifiable Information (PII)/Personal Health Information (PHI), plans and procedures modeled after the NIST Cybersecurity framework are required.
  • Common Data Elements (CDEs): Use of CDEs, especially for mental health human subjects research, is strongly encouraged to facilitate data sharing and standardization. Costs associated with CDE collection and submission to NDA should be included in the budget.
Project-Specific Requirements
  • Experimental Medicine Approach: Projects must focus on validating the presumed mechanism of action of the intervention through objective measures of target engagement rather than solely on clinical efficacy at this early stage.
  • Innovation Preference: The grant strongly encourages testing of interventions not previously approved/marketed for psychiatric disorders, including interventions in active development, repurposed agents/devices from non-CNS indications, or expanding uses of neuromodulatory devices to other indications/populations.
  • Multimodal Interventions: Accepted if the pharmacologic agent or neuromodulatory device is novel. Applications must provide a clear and careful description of the combination of therapies and how combination parameters (including dosage) will be assessed, aiming for positive synergy.
  • Pediatric Populations: For multimodal interventions in pediatric populations, a novel intervention should be paired with a previously established intervention (e.g., FDA approved/cleared). Repositioned drugs must already be approved for use in pediatric populations for non-psychiatric indications.
  • Specificity of Targets: NIMH is interested in novel molecular or circuit-based targets as they relate to functional domains or symptom(s) of mental disorders, rather than broad diagnostic categories.
Special Considerations
  • Suicide Outcomes: Where feasible and appropriate, intervention research is strongly encouraged to include assessment of suicidal behavior to advance understanding of how mental health interventions might impact suicide-relevant outcomes.
  • Staff Consultation: Applicants are strongly encouraged to consult with NIMH staff when developing their application to clarify policies, guidelines, and project consistency with program priorities.
