General Amendment Requests


The Institutional Animal Care and Use Committee recognizes that investigators may periodically need to make changes in their protocols after the Committee has granted final approval.  Regulatory agencies require that the Institutional Animal Care and Use Committee approve all significant changes prior to implementation (additional information can be found in the Review of Significant Changes to Approved Protocols SOP).

IACUC Policy

An amendment must be submitted via the eProtocol system. Amendments are reviewed and approved by the Institutional Animal Care and Use Committee (IACUC).  If during the review of the amendment request, it is determined that the requested change does not qualify as an amendment, a new IACUC Protocol Application must be submitted to the IACUC.  Approved amendments expire on the same date as the parent protocol.

IACUC Guidelines

All amendments must be incorporated into the appropriate sections of eProtocol. The following are examples of common amendments with requirements, some of which may be able to be approved administratively or by Veterinary Verification and Consultation (VVC) depending on requirements outlined in the Review of Significant Changes to Approved Protocols SOP:

  1. When modifying animal numbers – Add the animals to the table in the Species section and provide justification in question 2.

    1. Animal Use Justification section, question 1.c.i. Include a description of the biological characteristics (e.g., unique anatomic, physiologic, age or sex related characteristic or attribute) that make the animals requested the most appropriate for the described work.
    2.  Animal Breeding, Housing and Care section, question 3 if genetically engineered or mutant animals are requested. Describe the following:
      1. the genetic modification
      2. the anticipated phenotypic and physiologic consequences
      3. the method of monitoring presence of gene modification in animals and when it will be done
      4. any special care or monitoring required
      5. the scientifically-recognized nomenclature for all genetically engineered and mutant animals and source from which they will be obtained
