Human Subjects Research
The NIH has instituted new policies regarding applications for clinical trials. The NIH definition of a clinical trial is being broadly interpreted to encompass both therapeutic clinical trials, as well as mechanistic trials. Studies that have previously been considered physiologic studies or basic behavioral studies may now be considered clinical trials.
Additional information about the NIH definition of a clinical trial, including case studies and FAQs, is available on the NIH website.
One of the most important policy changes is that, starting Jan. 25, 2018, the parent NIH R01 FOA will no longer accept clinical trial applications. If your proposed clinical trial falls within the mission of NIDDK, you may be able to submit your application to PA-18-330 (see below). Additional policies include:
- expanded information required in applications proposing clinical trials
- additional review criteria for clinical trials
- the use of a single IRB for multi-center studies
- dissemination of trial results
- good clinical practice (GCP) training
NIDDK strongly recommends that you contact the Program Director responsible for your area of research before submitting an application proposal.
If you are applying for or have already received a clinical research grant you must follow both NIH and NIDDK policies for clinical research. You can also review the wide range of NIDDK Research Resources to help clinical researchers work more efficiently, lower costs, and improve effectiveness.
NIDDK funds pivotal clinical research through the application mechanisms outlined below.
Pilot/Feasibility Clinical Studies (R21)
The R21 mechanism provides support for exploratory, short-term clinical studies that investigate new ideas and novel approaches with less stringent requirements for preliminary data. Short-term studies should focus on research questions that are likely to have high clinical impact. Funding is provided through a series of disease-specific Funding Opportunity Announcements (FOAs). View open R21 FOAs from NIDDK.
Clinical Research (R01): One or Two Sites
For studies that involve up to two investigator sites, R01s may be used.
Multi-center Clinical Studies: Three or More Sites (U34/U01)
For studies that involve three or more investigator sites, NIDDK uses a two-part process that usually requires use of a U34 planning grant followed by a separate application for the clinical trial (U01).
Investigator-initiated Ancillary Studies to Major Ongoing Clinical Studies
Biosamples for Use in Research (X01)
Many of the large clinical studies funded by the NIDDK collect non- renewable biosamples, such as plasma and urine, and associated data for analysis and future study. Biosamples are stored in the NIDDK Central Repository. The X01 mechanism provides access for researchers who are interested in using these resources in their clinical studies. View PAR-17-270.
Research involving human subjects at NIH.
Allows researchers to refuse to disclose names or other identifying characteristics of research subjects in response to legal demands.
Helps NIH applicants and grantees understand their roles and responsibilities in relation to the Food and Drug Administration Amendments Act (FDAAA) of 2007.
Easy access to information on publicly and privately supported clinical studies.
OHRP provides leadership in the protection of the rights, welfare, and wellbeing of human subjects involved in research conducted or supported by HHS.
