The core objective of this grant is to identify new druggable targets for pain within the understudied druggable proteome. It aims to support pilot projects that generate preliminary data and tools for these targets, ultimately contributing to novel medications for pain and the opioid addiction cycle.
Explicit identification of target recipient type: This grant targets a broad range of research-focused entities, including higher education institutions, non-profits, for-profit organizations, and various governmental bodies with scientific research capacity.
Size: Not explicitly defined by employee count, but the 'R03 Small Grant Program' designation indicates a focus on projects of limited scope and budget.
SECTOR-SPECIFIC: This grant is highly sector-specific, focusing on HEALTHCARE, particularly biomedical research, pain management, and opioid addiction.
Geographic scope: Applicant organizations must be based in the United States. While foreign components (collaborators) are allowed, the primary applying entity must be U.S.-based.
Key filtering criteria for initial grant screening:
The project must focus on one or more of the explicitly listed understudied proteins within the NOFO.
The project must not involve clinical trials or clinical drug development studies.
The research must be related to pain and/or pain management.
The applicant organization must be U.S.-based.
Grant frequency: This is a recurring funding opportunity, noted as a reissue of a previous program (PAR-24-197).
Program context: This grant is part of the broader NIH HEAL Initiative (Helping to End Addiction Long-term), addressing the national opioid public health crisis.
Financial Structure
Budget limit: Application budgets are limited to $100,000 in direct costs for one year. Subcontract F&A (Facilities & Administrative) costs are excluded from this direct cost limit.
Project period: The maximum project period for an award under this NOFO is 1 year.
Matching funds: This funding opportunity does not require cost sharing.
Eligible costs:
Travel costs to support the attendance of one Program Director/Principal Investigator (PD/PI) at an annual 2-day, in-person HEAL Investigators meeting in the Washington DC area (for the 1-year duration).
Costs to ensure manuscripts are immediately publicly available upon publication (e.g., open access fees).
Ineligible costs: For NIH intramural scientists involved, salary and related fringe benefits for career, career conditional, or other Federal employees with permanent appointments, and costs related to administrative or facilities support (equivalent to F&A costs) are not eligible for direct funding through this grant. If an extramural application includes collaboration with an intramural scientist, no funds for the intramural scientist's support may be requested in the application.
Payment mechanism: Funding is provided as a grant, which is a financial assistance mechanism.

Evaluation Criteria
Overall Impact Score
Reviewers will assign an 'overall impact score' reflecting the project's likelihood to exert a sustained, powerful influence on the relevant research field(s).
Scored Review Criteria
Importance of the Research (Significance and Innovation): Evaluates the significance and innovative aspects of the proposed research project within the context of identifying new pain targets.
Rigor and Feasibility (Approach): Assesses the scientific soundness, methodological rigor, and overall feasibility of the proposed research plan to achieve its objectives within the small grant framework.
Expertise and Resources (Investigator(s) and Environment): Evaluates the qualifications, experience, and expertise of the investigator(s) in relation to the proposed work. For multiple Principal Investigator (MPI) applications, the quality of the leadership plan is also assessed. The adequacy and appropriateness of institutional resources for executing the project are also evaluated.
Additional Review Criteria (Not scored but considered for overall impact)
Protections for Human Subjects: If human subjects are involved, evaluation of justification, proposed protections against risks, potential benefits, and importance of knowledge to be gained. For exempt research, justification, involvement, and sources of materials are evaluated.
Vertebrate Animals: If live vertebrate animals are involved, evaluation of procedures, justification for animal use/species, interventions to minimize discomfort, and justification for euthanasia method if not standard.
Biohazards: If biohazardous materials or procedures are involved, evaluation of potential risks to personnel/environment and proposed protections.
Resubmissions: For resubmitted applications, the full application is evaluated as presented.
Additional Review Considerations (Not scored or affecting overall impact score, but reviewed)
Authentication of Key Biological and/or Chemical Resources: Assessment of plans for identifying and ensuring the validity of essential resources.
Budget and Period of Support: Evaluation of whether the proposed budget and requested project duration are justified and reasonable for the scope of the proposed research.
Relevance to Program Priorities: Consideration of how the proposed project aligns with NIH HEAL Initiative goals and contributes to increasing the variety of approaches applied to the study of understudied proteins.
