Funding Opportunity Purpose

The   objective of this limited competition Notice of Funding Opportunity (NOFO) is to solicit current or recently completed NHLBI K01, K08, K23, and K25 recipients for small grant support to expand their current research goals  or to branch out to a new study that resulted from the research conducted under the K award. Active NHLBI K01, K08, K23, and K25 recipients may apply for R03 support after the notice of award (NoA) for their first type-5 K awards has been issued. Recently completed NHLBI K01, K08, K23, and K25 recipients are eligible to apply for the R03 if the earliest possible R03 start date falls within 2 years of their prior NHLBI K award Project Period end date. This NOFO is intended to enhance the capability of NHLBI K01, K08, K23, and K25 recipients to conduct research as they complete their transition to fully independent investigator status.

This R03 program is intended to support research projects that can be carried out and completed within a short period of time (no more than two years) with limited resources and that may generate preliminary data to support a subsequent R01-equivalent application. These studies include, but are not limited to, pilot or feasibility studies; proof of concept studies; secondary analysis of existing data; small, self-contained research projects; development of new research methodologies or technologies, or development of novel experimental models. A minimum of 40% protected overall research effort, not necessarily limited to the proposed R03 project, is required from applicants. For current and previous K23 recipients, research proposed in the R03 application may or may not include patient-oriented research.

Section I. Notice of Funding Opportunity Description

Purpose/Research Objectives:

This R03 program aims to aid this effort by facilitating the transition to fully independent investigator status for NHLBI K recipients. This Limited Competition NOFO invites applications from NHLBI K01, K08, K23, and K25 recipients for small grant support. Active NHLBI K01, K08, K23, and K25 recipients may apply for R03 support after the notice of Award (NoA) for their first noncompeting (type-5) K award has been issued. Recently completed NHLBI K01, K08, K23, and K25 recipients are eligible to apply or resubmit (an A1 application) for the R03 if the earliest possible R03 start date falls within 2 years of their prior NHLBI K award Project Period end date. 

NIH has a longstanding interest and commitment to training and providing support for early stage investigators. Special programs, such as mentored career development (K) awards, to assist early stage investigators in obtaining independent research funding have been developed. Despite concerted efforts, the time to first independent award at first independent award has not decreased and many NHLBI K recipients still need additional support in their transition to research independence. The entry and sustainability of a well-trained and diverse cadre of early stage investigators, including individuals from underrepresented backgrounds (NOT-OD-20-031), into NIH-funded independent researchers is critically important to our nation’s biomedical research enterprise. NHLBI is committed to addressing this need.

Through this funding opportunity, NHLBI intends to support the science and research of the next generation of successful scientific leaders as they launch their independent research careers by augmenting previous investments and sustaining meritorious programs seeking R01-equivalent grant support. The added small grant support is expected to have the following benefits:

  • Contribute to fiscal independence for the award recipient as a precursor to attaining research independence
  • Support the recipient as they generate additional preliminary data and increase scientific output
  • Provide an opportunity to demonstrate additional success in the peer review process during the course of their career development
  • Promote subsequent R01-equivalent grant applications and increase the chance for success

Specific Areas of Research Interest:

The support provided by this R03 program will enable former and current NHLBI K01, K08, K23, and K25 recipients to expand their current research objectives or to branch out to a new study that resulted from the research conducted under the K award. The R03 research projects shall be carried out and completed within a short period of time (no more than two years) with limited resources, which may generate preliminary data to support a subsequent R01-equivalent application. These studies may include, but are not limited to, pilot or feasibility studies; proof of concept studies; secondary analysis of existing data; small, self-contained research projects; development of new research methodologies or technologies; or development of novel experimental models.

NHLBI encourages every K01, K08, K23, and K25 recipient to apply for R01-equivalent grant support during the course of their career development awards. According to NIH policy, K recipients may now receive concurrent salary support from an NIH career development award and a research grant under certain circumstances (see NOT-OD-08-065). However, any K01, K08, K23, or K25 recipient who has previously been awarded a substantial NIH independent research award will no longer be eligible to receive an R03 under this R03 program. The definition of substantial NIH independent research award is included in Definition of New Investigator.

See Section VIII. Other Information for award authorities and regulations.

Investigators proposing NIH-defined clinical trials may refer to the Research Methods Resources website for information about developing statistical methods and study designs.

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 announcement, note the following:

The R03 small grant supports discrete, well-defined projects that realistically can be completed in two years and that require limited levels of funding. Because the research project usually is limited, an R03 grant application may not contain extensive detail or discussion. Accordingly, reviewers should evaluate the conceptual framework and general approach to the problem. Appropriate justification for the proposed work can be provided through literature citations, data from other sources, or from investigator-generated data. Preliminary data are not required, particularly in applications proposing pilot or feasibility studies.

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 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.

Scored Review Criteria

Reviewers will evaluate 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 criterion score. 

 

Significance

  • 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.

Innovation

  • 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.
 

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).

Rigor:

  • 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.

Feasibility:

  • 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 an appropriately diverse population of participants. Additionally, evaluate the likelihood of successfully achieving the proposed enrollment based on age, racial, ethnic, and sex/gender categories.
  • For clinical trial applications, evaluate whether the study timeline and milestones are feasible.

 Specific to this NOFO:

  • Evaluate the discussion of how the proposed work in the R03 application evolved from the K award research project.
 

Investigator(s)

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.

Environment

Evaluate whether the institutional resources are appropriate to ensure the successful execution of the proposed work.

Specific to this NOFO:

  • Evaluate whether the benefit of R03 support to the applicant's plans, progress and path to independence has been adequately explained and justified, and the likelihood that the proposed work will lead to an independent line of investigation.
  • Evaluate the adequacy of the letter from the mentor or Department/Division Head in supporting the applicant's potential to become an independent investigator.
