Standard Operating Procedure Table of Contents


To enable investigators to resubmit their applications when their initial peer review results are not in the fundable range.


For unfunded applications, an investigator may resubmit an application once within 37 months of the application's original receipt date. The resubmission must address reviewer comments from the original application's summary statement. For details, see Clarification: Time Limit on NIH Resubmission Applications.

Note: new investigators resubmitting R01 applications have at least one month to revise and resubmit for the next review cycle. They receive their summary statements no later than March 10, July 10, or November 10, and instead of following the standard resubmission deadlines, can resubmit by April 10, August 10, or December 10, respectively.

Investigators and Applicants

  • Include an introduction that addresses the previous summary statement and indicates how your resubmission differs from the previous submission. For an electronic application, the introduction is a PDF attached to the PHS 398 Research Plan component.
  • Usually mark revisions in the text of the Research Plan so reviewers can easily discern what has changed. But if revisions are so extensive that virtually all text would be marked, explain changes in the introduction only.
  • If your application in response to an RFA did not succeed and you want to submit it again, convert it into a new investigator-initiated application.
  • Follow our advice for timing and other matters.
  • If you are not funded after the initial submission and one resubmission, you must submit a new research application with a significant change in direction and approach.


Applicants with questions should read Communicating With NIAID—How to Get Help.
