When you are ready to resubmit your application, you should contact your assigned program officer for guidance in addressing the comments in your summary statement.

See Frequently Asked Questions about resubmissions of applications for details about current NIH policy and to learn about the difference between a new application and a resubmission.

While NIH does not limit the number of times you can resubmit an application with essentially the same content and scope as an earlier application, it is not allowable to have overlapping applications under review at the same time. Details can be found in Guide Notice NOT-OD-14-074:

  • Two applications with overlapping aims may not be under review at the same time.
  • A resubmission (A1) application may not be submitted before issuance of the summary statement from the review of the previous new application.
  • A new application may not be submitted before issuance of the summary statement from the review of the previous overlapping new or resubmission application.
  • Two applications with overlapping aims cannot be under review at the same time, even if they are for different activity codes (e.g. R01, R21) or if they are submitted to different funding opportunity announcements.
  • An application may not be submitted if it has substantial overlap with another application pending appeal of initial peer review. See NOT-OD-11-101.

The NIH will not accept a resubmission application that is submitted later than 37 months after the submission of the new application that it follows. See NOT-OD-12-128 and NOT-OD-10-140 for details.
