5. Check your announcement to see if single or multiple Principal Investigators (PIs) are allowed. For
applications designating multiple PDs/PIs, a Multiple PD/PI Leadership Plan must be included.
For more information about Multiple PD/PIs, please go to
http://grants.nih.gov/grants/multi_pi/faq.htm.
6. Purpose and scope: The R21 is intended to encourage exploratory/developmental research by
providing support for the early and conceptual stages of project development. Through this
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 includes:
Exploratory, novel studies that break new ground or extend previous discoveries toward new
directions or applications.
High-risk, high-reward studies that may lead to a breakthrough in a particular area, or result
in novel techniques, agents, methodologies, models, or applications that will impact
biomedical, behavioral, or clinical research.
Projects should be distinct from those supported through the traditional R01 code. Long-term
projects, or projects designed to increase knowledge in a well-established area, are not appropriate for
this FOA.
7. Budget Information: You may request a project period of up to 2 years. The combined budget for
direct costs for the two-year project period may not exceed $275,000. No more than $200,000 may
be requested in any single year. Individual FOAs may require additional budget information.
Review the Application and Submission Information section of the FOA for detailed
instructions.
8. Title: Limited to 200 characters (includes spaces and punctuation marks).
9. Project Summary (Abstract):
No longer than 30 lines of text.
Succinct and accurate description of the proposed work, able to stand on its own (separate
from the application). Should be informative to other persons working in the same or related
fields and understandable to a scientifically literate reader. Avoid both descriptions of past
accomplishments and the use of the first person.
State the application's broad, long-term objectives and specific aims, making reference to the
health relatedness of the project (i.e., relevance to the mission of the agency). Describe the
research design and methods for achieving the stated goals. Be sure that the project
summary reflects the key focus of the proposed project so that the application can be
appropriately categorized. Do not include proprietary, confidential information or trade

secrets in the project summary. If the application is funded, the project summary will be
entered into an NIH database and made available on the NIH Research Portfolio Online
Reporting Tool (RePORT) and will become public information. Note that the "Project
Summary/Abstract" attachment is not same as the "Research Strategy" attachment.
10. Project Narrative:
No more than 3 sentences.
Describe the relevance to public health: how, in the short or long term, the research would
contribute to fundamental knowledge about the nature and behavior of living systems and/or
the application of that knowledge to enhance health, lengthen life, and reduce illness and
disability. If the application is funded, this public health relevance statement will be
combined with the project summary (above) and will become public information.
10. Biographical Sketch:
NOTE: The summary below covers applications with due dates before January 25, 2022. For
applications due on or after January 25, 2022, please see the updated instructions on the NIH’s

This section includes three headings: Significance, Innovation, and Approach.
For this particular activity code, note the following: 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.
A. Significance:
Explain the importance of the problem or critical barrier to progress in the field that the
proposed project addresses.
Explain how the proposed project will improve scientific knowledge, technical capability,
and/or clinical practice in one or more broad fields.
Describe how the concepts, methods, technologies, treatments, services, or preventative
interventions that drive this field will be changed if the proposed aims are achieved.
