Protocol Review

Proposal Documents

The IACUC regulates the use of animals by requiring investigators to submit a "Proposal to Use Laboratory Animals in Research and Teaching" and controls the use of animal tissue through the form entitled "Request to Use Fresh or Frozen Animal Tissues in Research and Teaching." The IACUC proposal is periodically revised to enhance Committee review, improve project design, and provide information that will heighten the awareness of UofL scientists regarding humane animal care and use. Please refer to the "Forms" section in order to access new/renewal or tissue proposal materials.

Review Process

The IACUC reviews all animal use proposals and requests to use animal tissue, including those involved in pilot and/or internally funded research. Proposals must be submitted by Project Directors prior to the start of related research or teaching activities. Each large-animal proposal is subject to an annual review; continued approval may be granted during the annual review process. A newly revised application must be submitted at the end of three years.

Proposals are initially submitted to IACUC via the web-based iRIS module accessible at proposals are then subjected to a pre-review by the Animal Compliance Specialist (ACS) as well as the Training Specialist (TS).  The TS will check participant's training history to confirm appropriate Occupational Health and Safety Program enrollment as well as to make sure each participant listed on the proposal has a Training Log.  After the ACS has completed review, there is a veterinary pre-review by the RRF veterinary staff. During the review process, the ACS, TS and veterinarian might require PIs to satisfactorily address stipulations before their approval is given and advancing on to the next reviewers.  While concentrating on animal welfare and husbandry issues, these pre-reviews also ensures proposal accuracy and completeness, which in turn, facilitates IACUC review.

Following the pre-reviews, proposals are assigned to a designated reviewer and possibly 1-2 reviewer consultants, depending upon the complexity of the project. The designated reviewer is selected from the IACUC membership; the reviewer consultant may be an IACUC member or, infrequently, may be an outside consultant. IACUC review is usually completed within two months again depending on the complexity of the project. All reviewer comment's and concerns are forwarded to the designated reviewer, who serves as the intermediary between the committee and the project director and receives any necessary stipulations or clarifications. This may require additional interaction between the designated reviewer and reviewer consultant to completely address all concerns. Once all issues have been satisfactorily addressed, the designated reviewer instructs the Chair to approve the proposal; this information is then relayed to the IACUC Office.

The IACUC prepares weekly action reports that are forwarded to all IACUC members. These reports contain a list of all proposals that are under review (including project director, title, species, procedure codes, date submitted, status, lay summary and primary reviewer). Any IACUC member requesting additional information is provided a copy of the proposal in question. At any time during the review process, an IACUC member may request full committee review (FCR). FCR requires that the proposal be discussed during a monthly, convened meeting of the IACUC prior to any official decision.

While encompassing all aspects of the proposal, Committee review places special emphasis on the significance of study goals weighed against the potential harm that may be imposed on animals that serve as models for human disease. Decisions involving proposal disposition (approval, contingent approval, or disapproval) are made only after consideration has been given to other research methods that may not involve animals and a written assurance that proposed activities do not unnecessarily duplicate previous experiments. The Committee also addresses the ethics of animal or tissue use by considering the animal and human health benefits and/or other societal good that is likely to accrue from the proposed research. With respect to the review of protocols that have a potential to cause pain or distress, committee members focus on the proposal section devoted to the consideration of alternatives to painful procedures. A written narrative description of the methods and sources used to determine that alternatives were not available is required before a project may receive IACUC approval. When the Committee is satisfied that the project director has addressed the issue of alternatives and determined that there is no way to avoid the potential for pain and distress, the use of analgesics and anesthetics is reviewed. All proposals require the use of appropriate methods and/or agents to minimize pain or distress and a detailed description of sedatives, analgesics and/or anesthetics to be used must be given.

The UofL IACUC will not consider proposals that are characterized by the likelihood of severe, prolonged, or unrelieved pain or distress without comprehensive and explicit scientific justification. Such protocols would also be placed on higher priority for thorough scrutiny during the annual review and semi-annual laboratory inspection processes.
