Types of IRB Review

To submit an application to the IRB, an appropriate level of review must be requested. The IRB will verify or correct the level of review requested for an IRB submission.


What doesn’t need IRB review

Not Human Subjects Research (NHSR)

A Not Human Subjects Research (NHSR) submission is a short application in iStar to determine if a project requires IRB review. Studies are considered “Not Human Subjects Research” when they do not meet the definitions of human subjects and/or research.

What needs IRB Review

Human Subjects Research

Any activity that fits the federal definition of both “research” and “human subjects” or the FDA definitions of “clinical investigation” and “human subjects” is considered human subjects research.


Levels of IRB Review

Human subjects research is reviewed by an IRB according to the following categories:

Exempt Review

Research can be approved as “exempt” if it is no more than “minimal risk” and fits one of the 6 federally designated exempt review categories. Studies that may qualify for “Exempt” must still be submitted to the IRB for review.

Expedited Review

Research can be approved as “expedited” if it is no more than “minimal risk” and fits in one of the 9 federally designated expedited review categories.

Full-Board Review

Research that does not qualify for expedited or exempt review (presents more than minimal risks to subjects) will receive review at a fully convened IRB committee meeting.


Duration of IRB Approval (Continuing Review)

Every IRB approved study must receive continuing review “not less than once per year”, per federal regulation. An approval period cannot exceed 364 days. In some cases, the IRB may grant a shorter approval period if the risk level merits more frequent review.

To continue a study beyond the period for which it was initially approved, a Continuing Review application must be submitted. Studies that require Continuing Review will receive email notifications from iStar with instructions for how to submit a Continuing Review application.

What if study approval lapses?

If the expiration date has lapsed, the investigator must email the IRB a request to continue study subjects currently on the trial and/or continue data analysis. The investigator will receive confirmation from the IRB. The investigator may not recruit or enroll new subjects until the study’s continuing review has been reviewed and approved by the IRB.
