You can submit a modification at any time, as long as the protocol is not currently under review.

Review time will depend on the complexity of the modification. Administrative modifications, which include addition or deletion of personnel and/or funding, can generally be approved within 2-3 days. Modifications adding new procedures usually take 2-8 weeks, depending on complexity.

Yes, you can let your protocol expire. To do this, please send an email to [email protected]  indicating: 1) the date you will cease animal work, and 2) what should happen to any remaining animals that are still in the animal facility under your protocol.

If you do not intend to reactivate the protocol, please let the IACUC office know that they can retire the protocol.

If your protocol expires, all work with vertebrate animals must stop immediately. You are not allowed to conduct research on animals until the protocol is approved. Federal funds cannot be used to pay per diems or animal support costs during the period of expiration.

However, laboratory personnel are responsible for working with their LARC manager to ensure that animals on study receive appropriate care while the protocol is expired. This may include:

• PI feeding or watering animals (e.g. antibiotic feed or water, special diets)

• Medications, including antibiotics and analgesics
• Visually observing animals for pain, distress, or ill health (e.g. seizures)
• Measurements needed to evaluate health status (e.g. blood glucose, measuring tumor size)
• Maintenance of implants or other medical devices

Breeding animals do not need to be separated, and lab staff should continue to wean litters; however, new breeding pairs are not allowed

Yes, you can reactivate an expired protocol. Contact the IACUC office before reactivating if your protocol has been expired for more than 6 months.

Yes, RIO allows you to make changes to the protocol at the same time as an annual renewal – select the “renewal with modifications” button on the renewal tab.

NOTE: If you have minor changes to make, these are usually fine to include with the annual renewal and should not delay approval. Minor changes include reducing animal numbers, deleting species, deleting procedures, adding or deleting personnel.

However, if you have significant changes, this may delay your annual renewal due to longer review time. We strongly suggest you submit and obtain approval of the annual renewal application first, then submit the modification.

If you have already started a modification application, RIO will not allow you to add an annual renewal. Please contact [email protected] to cancel your modification if you wish to renew the protocol.

Please retire all of your IACUC protocols in RIO, or request that they be transferred to another PI in your department. Email us at [email protected] with your request, and we’ll take care of the rest.

You should also contact LARC to make arrangements for any remaining animals on your protocol, and let the Office of Sponsored Research know that you have completed your animal work at UCSF.
