What happens to my application if I don't get funded? 

If an application does not result in funding, there may be an opportunity to respond to the reviewers’ comments and resubmit the application within the appropriate timeframe. Applicants seeking advice beyond that available online may want to contact the NIH Program Officer listed at the top of the summary statement (see https://grants.nih.gov/grants/policy/amendedapps.htm for more information).
