Other Information Part 2. Full Text of Announcement Section I. Notice of Funding Opportunity Description The evolution and vitality of the biomedical, behavioral, and clinical sciences require a constant infusion of new ideas, techniques, and points of view.

These may differ substantially from current thinking or practice and may not yet be supported by substantial preliminary data. Through the NIH Exploratory/Developmental Research Grant Program, the NIH seeks to foster the introduction of novel scientific ideas, model systems, tools, agents, targets, and technologies that have the potential to substantially advance biomedical, behavioral, and clinical research.

This program is intended to encourage new exploratory and developmental research projects. For example, such projects could assess the feasibility of a novel area of investigation or a new experimental system that has the potential to enhance health-related research. Another example could include the unique and innovative use of an existing methodology to explore a new scientific area.

These studies may involve considerable risk but may lead to a breakthrough in a particular area, or to the development of novel techniques, agents, methodologies, models, or applications that could have a major impact on a field of biomedical, behavioral, or clinical research. Applications for Exploratory/Developmental Research Grant awards should include projects distinct from those supported through the traditional R01 activity code.

For example, long-term projects, or projects designed to increase knowledge in a well-established area, are not appropriate for this NOFO. Applications submitted to this NOFO should be exploratory and novel. These studies should break new ground or extend previous discoveries toward new directions or applications.

Projects of limited cost or scope that use widely accepted approaches and methods within well-established fields are better suited for the NIH Small Research Grant Program .

This Notice of Funding Opportunity does not accept applications proposing clinical trial(s) Applications are assigned to participating Institutes and Centers (ICs) based on receipt and referral guidelines and applications may be assigned to multiple participating ICs with related research interests.

Applicants are encouraged to identify a participating IC that supports their area of research via the R21 IC-Specific Scientific Interests and Contact website and contact Scientific/Research staff from relevant ICs to inquire about their interest in supporting the proposed research project.

Section V. Application Review Information 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. 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. 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 scored review criteria and additional review criteria (as applicable for the project proposed).

An application does not need to be strong in all categories to be judged likely to have a major scientific impact. Reviewers will consider Factors 1, 2 and 3 in the determination of scientific merit, and in providing an overall impact score. In addition, Factors 1 and 2 will each receive a separate factor score.

Factor 1. Importance of the Research (Significance and Innovation) Evaluate the importance of the proposed research in the context of current scientific challenges and opportunities, either for advancing knowledge within the field, or more broadly. Assess whether the application addresses an important gap in knowledge in the field, would solve a critical problem, or create a valuable conceptual or technical advance.

Evaluate the rationale for undertaking the study, the rigor of the scientific background for the work (e.g., prior literature and/or preliminary data) and whether the scientific background justifies the proposed study. Evaluate the extent to which innovation influences the importance of undertaking the proposed research.

Note that while technical or conceptual innovation can influence the importance of the proposed research, a project that is not applying novel concepts or approaches may be of critical importance for the field. Evaluate whether the proposed work applies novel concepts, methods or technologies or uses existing concepts, methods, technologies in novel ways, to enhance the overall impact of the project. Factor 2.

Rigor and Feasibility (Approach) Evaluate the scientific quality of the proposed work. Evaluate the likelihood that compelling, reproducible findings will result (rigor) and assess whether the proposed studies can be done well and within the timeframes proposed (feasibility). Evaluate the potential to produce unbiased, reproducible, robust data.

Evaluate the rigor of experimental design and whether appropriate controls are in place. Evaluate whether the sample size is sufficient and well-justified. Assess the quality of the plans for analysis, interpretation, and reporting of results.

Evaluate whether the investigators presented adequate plans to address relevant biological variables, such as sex or age, in the design, analysis, and reporting. For applications involving human subjects or vertebrate animals, also evaluate: the rigor of the intervention or study manipulation (if applicable to the study design). whether outcome variables are justified.

whether the results will be generalizable or, in the case of a rare disease/special group, relevant to the particular subgroup. whether the sample is appropriate and sufficiently diverse to address the proposed question(s). For applications involving human subjects, including clinical trials, assess the adequacy of inclusion plans as appropriate for the scientific goals of the research.

Considerations of appropriateness may include disease/condition/behavior incidence, prevalence, or population burden, population representation, and/or current state of the science. Evaluate whether the proposed approach is sound and achievable, including plans to address problems or new challenges that emerge in the work.

For proposed studies in which feasibility may be less certain, evaluate whether the uncertainty is balanced by the potential for major advances. For applications involving human subjects, including clinical trials, evaluate the adequacy and feasibility of the plan to recruit and retain a study population that appropriately models the target population.

Additionally, evaluate the likelihood of successfully achieving the proposed enrollment based on age, race, ethnicity, and sex. For clinical trial applications, evaluate whether the study timeline and milestones are feasible. Factor 3.

Expertise and Resources (Investigator(s) and Environment) Evaluate whether the investigator(s) have demonstrated background, training, and expertise, as appropriate for their career stage, to conduct the proposed work. For Multiple Principal Investigator (MPI) applications, assess the quality of the leadership plan to facilitate coordination and collaboration.

Evaluate whether the institutional resources are appropriate to ensure the successful execution of the proposed work. Additional Review Criteria As applicable for the project proposed, reviewers will consider the following additional items while determining scientific and technical merit, but will not give criterion scores for these items, and should consider them in providing an overall impact score.

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, 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, 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 research includes Vertebrate Animals, evaluate the involvement of live vertebrate animals 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.

For additional information on review of the Vertebrate Animals section, please refer to the Worksheet for Review of the Vertebrate Animals Section . When the proposed research includes Biohazards, evaluate whether specific materials or procedures that will be used are significantly hazardous to research personnel and/or the environment, and whether adequate protection is proposed.

As applicable, evaluate the full application as now presented. As applicable, evaluate the progress made in the last funding period. As applicable, evaluate the appropriateness of the proposed expansion of the scope of the project.

Additional Review Considerations As applicable for
