Stanford as Relying IRB

Main content start

Overview

Stanford may enter into a reliance agreement to rely on an external IRB for Single IRB review. This is sometimes referred to as "ceding" IRB review.

When will Stanford Agree to Rely on an External IRB?

When not required by the federal regulations, reliance on an external IRB is considered on a case-by-case basis.

  • Stanford will generally rely on an external IRB for review when required per NIH Single IRB policy and the Common Rule Cooperative Research provision.
  • Stanford will consider reliance when the lead PI or the research consortium requires the use of single IRB to participate in the research.
  • Stanford will not rely on an external IRB when Stanford is the only participating site.

Examples of when reliance may not be appropriate include:

  • first-in-human drug or device studies,
  • certain studies using biological agents or recombinant DNA vectors, and
  • studies involving stem cells. 

If you are unsure whether your study meets the general criteria for the Stanford IRB to rely on an external IRB, please contact the Single IRB team.

What Does it Mean for Stanford to Rely on an External IRB?

The Reviewing IRB is responsible for ensuring federal and state regulations (including the Common Rule and FDA requirements) for IRB review are met. The Reviewing IRB is responsible for conducting initial and continuing reviews, and reviewing modifications and reportable events (including reports of serious and/or continuing noncompliance and unanticipated problems).

The Stanford IRB maintains responsibility for local review requirements including:

The reliance terms are outlined in a reliance agreement.

What is Needed for Stanford to Rely on an External IRB?

The Stanford Investigator will need to submit a 'Stanford Relying' application in eProtocol to request reliance on an external IRB. The eProtocol application should include:

  • Reviewing IRB approved study protocol;
  • Reviewing IRB approved consent form (with Stanford required elements included);
  • IRB Reliance document (check with Reviewing IRB; not needed if using a Master Reliance Agreement);
  • Investigator Brochure and/or FDA documentation (if applicable);
  • Reviewing IRB initial approval letter for the overall study (this typically does not include approval to add Stanford as a site); and
  • Local Context document if requested by Reviewing IRB.

What are the Protocol Director’s Responsibilities when Relying on an External IRB?

The Protocol Director’s additional responsibilities are outlined in the SMART IRB’s Relying PI Checklist.

Are there Fees when Stanford Relies on an External IRB?

The Stanford IRB charges initial and continuing review fees for industry-sponsored clinical trials. See Industry Fees for IRB Review for fee schedule.

NCI CIRB Initiative

For certain national, multi-center cooperative oncology group (COG) cancer treatment trials the Adult and Pediatric CIRBs serve as the Reviewing IRBs.
