The single IRB (sIRB) mandate is a set of complementary federal policies that require certain types of federally-funded research that involve multiple institutions to use one IRB to accomplish IRB review and approval for all of the institutions conducting the study/trial. The Single IRB Model allows multiple institutions that conduct the same protocol to cede to a single IRB for review. The NIH Single IRB Policy and Common Rule Cooperative Research Requirement are the two policies that require the use of a Single IRB.
Effective January 25, 2018: All competing NIH grant applications (new, renewal, revision or re-submission) for multi-site studies with NIH receipt dates on or after January 25, 2018, must include a plan describing the use of a sIRB for the study.
- Applies to: Domestic sites of NIH funded studies where each site will conduct the same protocol involving non-exempt human subjects research, whether supported by grants, cooperative agreements contracts or the NIH Intramural Research Program.
- Exceptions: VA sites; international sites; sites involving tribal nations.
Effective January 20, 2020: Projects sponsored by signatories of the revised Common Rule, involving multiple research locations conducting human subjects research, with IRB approval dates on or after January 20, 2020, must use a sIRB. This is mandated by the Cooperative Research provision which expands upon and supersedes the NIH’s Single IRB policy.
- Applies to: All sites in the United States participating in a federally funded cooperative research study (involves more than one site).
- Exceptions: Cooperative research for which more than single IRB review is required by law (including tribal law passed by the official governing body of an American Indian or Alaska Native tribe); or Research for which any Federal department of agency supporting or conducting the research determines and documents that the use of a single IRB is not appropriate.
