Applying for, Renewing, and Modifying Protocols

The OUHSC IACUC uses TOPAZ for New Protocol Submissions, Amendments and Annual Updates


Protocol Submission Deadlines


Classification System for all New Protocol Submissions


  • Class I - any protocol using USDA-regulated species requires at least two designated member reviews
  • Class II - any protocol using non-USDA-regulated species that involves a surgical procedure requires at least one designated member reviews
  • Class III - any protocol using non-USDA-regulated species that does not involve a surgical procedure requires at least one designated member reviews


Standard Protocols

ATTENTION! The deadline for submitting new protocols has changed! Please plan accordingly!


  • Reviewed monthly.
  • The submission deadline for new protocols is the last Wednesday of each month.
  • Median turnaround is about 5 weeks.


Eligibility: All protocols.


Before submitting a new protocol, check out 'TOPAZ Animal Use Protocol Tips & Guidelines' under the Policies, Procedures, Guidelines section of this webpage.


Rapid Review


  • Rolling submission.
  • Median turnaround is about 20 days.


Eligibility: JIT awards requiring a fast turnaround. Contact the IACUC Office for more information.


Amendment Review


  • Rolling submission.
  • Amendments for minor (i.e., personnel changes) and significant (i.e., procedural changes) types of amendments are handled separately.
  • Median turnaround for minor changes is 3 days. However, all IACUC and EHSO training requirements must be completed prior to approval.
  • Median turnaround for significant changes is 5 days.
  • Expedited amendment review may be available for extenuating circumstances. Contact the IACUC Office for more information.


Annual Review


  • Occurs on the first and second anniversary dates of original protocol approval.
  • Principal Investigators are prompted via email for submission 60, 30, and 15 days before the 1st and 2nd anniversary of original approval.
  • Complete the Annual Update Form on the TOPAZ website.
  • Significant changes must be submitted for amendment review prior to the Annual Update.
  • Detailed procedures entitled "Handling Annual Updates" are now available in the Policies, Procedures, and Guidelines section of the website.


Three-year De Novo Review


  • All protocols require de novo review from the IACUC every three years.
  • Principal Investigators should resubmit a new protocol to continue a project at least 2 months before the 3rd anniversary of original approval.
  • Principal Investigators are prompted via email that a protocol will soon expire 90, 60, and 30 days before the expiration date.
  • Approved protocols may be duplicated for resubmission, although they must receive a new assigned number from the IACUC.
  • De Novo reviews will follow the same classification system as all new protocol submissions. Contact the IACUC Office for more information.
  • If a replacement protocol has not been received and approved by the IACUC, the protocol will be administratively inactivated on the expiration date.
  • Once a protocol is expired, all protocol-related activities must cease, including breeding, and the principal investigator will be responsible for any per diem and animal care charges.
