NIH recently released new requirements and expectations that impact users of controlled-access data; NIH-supported repositories that store controlled-access data; and NIH systems that provide access to controlled-access data. Please read the new guidelines to understand more about these expectations and reach out to NIDDK-CRsupport@niddk.nih.gov with any questions.

NIH has updated the security standards for controlled-access data repositories. Starting June 30, 2025, NIDDK-CR is enforcing the Requestor role as outlined in the Data and Resources Use Agreement (DUA). According to the DUA, the Requestor, also known as the Principal Investigator (PI), is the individual submitting the request for Data or Resources, must be a permanent employee of the Requesting Institution, and must have oversight authority to be primarily responsible for the Research Project. In line with NIH guidance, trainees, laboratory technicians, research assistants, graduate students, postdocs, and others without oversight authority are not eligible to submit a Data or Resource request.

Requests submitted and approved before June 30, 2025, with a Requestor who does not meet the defined criteria, are asked to identify a new PI no later than the Access Renewal period (1 year from the DUA effective date). If a suitable new PI cannot be identified, the request will be t. . .

In support of recent security directives, the NIH has implemented updates to data security and oversight standards to protect controlled-access data provided by NIH-controlled-access repositories, including NIDDK-CR. As a result, NIDDK-CR released updated templates for its Data and Resources Use Agreement (DUA) and Material Transfer Agreement (MTA) on May 1, 2025.

The updated DUA (version 5) and MTA (version 3) address NIH data security standard requirements and clarify users’ commonly asked questions. Data/Resource requests and Data/Resource submissions initiated after May 1, 2025, are required to use the updated versions. Requests approved before May 1, 2025, are expected to adhere to the terms of use in the new version by the time of their Access Renewal (1 year from the DUA effective date).

NIDDK-CR is in the process of updating the Data and Resources Use Agreement (DUA) template and Material Transfer Agreement (MTA) template language in alignment with NIH’s security practices in addition to clarifying users’ commonly asked questions. Users can expect an updated Security and Non-transferability section to address NIH security policy updates; the MTA has updated the Terms of Agreement and codified standardized use limitations. Check back soon to find links to the updated templates.

NIDDK-CR staff compiled several commonly asked DUA questions and updated the FAQs with a new DUA subsection. The FAQs page can be found here.

As of January 25, 2023, the NIH Policy for Data Management and Sharing (DMS) is in effect. All research that is funded in whole or in part by NIH is required to submit a DMS plan outlining how scientific data and accompanying metadata will be managed and shared. NIH DMS plans should address the elements described in the Supplemental Information to the NIH DMS Policy. NIH has provided a DMS plan format on the Writing a Data Management and Sharing Plan page on the

This revamped, streamlined process for requesting biospecimens incorporates user feedback to better facilitate access to biospecimens. Certain requests will still require an X01 Resource Access Award; however, many will need only an administrative review or will leverage existing grant applications peer review if one was submitted. The new request process is designed to share NIDDK-CR resources with more researchers faster and easier to continue fostering innovative research. Researchers can visit the Material Counts page to explore the available resources and start a request.

Vivli and the National Institute of Diabetes and Digestive and Kidney Disease (NIDDK), part of the National Institutes of Health (NIH), will be working together to broaden exposure and strengthen NIDDK data ecosystem. As part of Vivli’s award to serve as one of six generalist repositories that will work with the NIH Office of Data Science Strategy under its Generalist Repository Ecosystem Initiative (GREI), NIDDK will include NIDDK Central Repository (NIDDK-CR) resources in the Vivli global clinical research data sharing platform. NIDDK-CR’s resources inclusion within Vivli as part of GREI improves discoverability and reuse of NIDDK-CR hosted resources making data more Findable, Accessible, Interoperable, and Reusable (FAIR), increases the scientific value by providing additional opportunities to the NIDDK scientific community, and maximizes the contributions of research participants.

The NIDDK Central Repository (CR) plays a crucial role in making data Findable, Accessible, Interoperable, and Reusable (FAIR). To enhance FAIRness of studies in the Repository, NIDDK and Booz Allen Hamilton, the current Data Repository contractor, have piloted a natural language processing (NLP) pipeline project for harmonizing study variables with NIH CDEs and for identifying potential new CDEs from dataset variables mapped to ontology concepts. Initial results show highly specific mapping of variables to CDEs as well as successful identification of relevant concepts for new CDEs. The pipeline can be refined and applied to other studies to potentially improve FAIRness of the NIDDK CR. Contact Dr. Rebecca Rodriguez with any questions.
