National Institutes of Health (NIH)Since April 7, 2008, the NIH has required the Principal Investigator (or their delegate) deposit the full text of all journal articles arising from NIH funded research studies into the PubMed Central database http://www.ncbi.nlm.nih.gov/pmc/. From January 18, 2017 for NIH funded clinical trials involving U.S. Food and Drug Administration-regulated drug, biological and device products, the DHHS also requires the registration of the clinical trial on the clinicaltrials.gov database within 21 days of the enrollment of the first study participant, and that study population characteristics and summary results data be deposited in the clinicaltrials.gov database no later than 12 months after study completion (see entry below for the text of the "final rule"). From January 25, 2023, NIH grant applications, proposals for contracts, NIH Intramural research projects, and other funding agreements, must comply with the final NIH Policy for Data Management and Sharing (DMS Policy) described below in NOT-OD-21-013 whereby the NIH requires researchers to prospectively plan for how scientific data will be preserved and shared through submission of a Data Management and Sharing Plan. NOT-OD-17-050 advises that since preprints are not published in peer-reviewed journals, they do not fall under the NIH public access policy.
