It takes two to MOU

When evaluating this scenario, OLAW provides clear guidance on IACUC oversight of interinstitutional collaborations. Institutions should have formal written contracts outlining the responsibility for “offsite animal care and use, animal ownership, and IACUC review.”1 If the research is sponsored by federal funding, the NIH Grants Policy further requires the agreement to incorporate applicable PHS Policy requirements for review and approval of proposed animal activities, significant changes, and semiannual IACUC program review.2 The PHS Policy requires that the research be conducted within an assured institution, whose IACUC would have purview.3,4

If both Great Eastern University (GEU) and the CRO are assured, Dr. Mayfield is correct in that there is no federal requirement for dual IACUC review4 and it becomes undue university-level regulatory burden. However, the institutional IBC is a separate entity with a different role, as defined by the NIH Guidelines. Regulatory guidance involving interinstitutional IBC collaborations is lacking, and Mayfield should not assume that OLAW’s policy applies. The NIH Guidelines state that “each institution (and the [IBC] acting on its behalf) is responsible for ensuring that all research… conducted at or sponsored by that institution is conducted in compliance with the NIH Guidelines.”5 Since GEU is sponsoring the study, its IBC remains responsible for oversight in a manner in which it feels is most appropriate. One could argue that because GEU does not have BSL-3 facilities, its IBC may lack the necessary expertise to perform a proper risk assessment of the proposed activities at the CRO; however, that is irrelevant because it is within GEU IBC’s authority to halt the study.

Extending from these observations, it is clear for this scenario that the establishment of a Memorandum of Understanding (MOU) between GEU and the CRO is the most appropriate path forward. Prior to its finalization, the MOU needs to not only clarify the roles and responsibilities for the project, both administratively and clinically, but it also needs to assuage the fears of GEU’s IBC. Although rooted in caution, the IBC’s concerns of an escaping mouse need to be critically evaluated with a thorough risk assessment. In the authors’ experience, mice escaping from their cages is a rare event, and even rarer then for the animal to escape the room and subsequently escape from the facility. Moreover, due to infrastructure in place in ABSL3 facilities, such an escape is even less likely to occur. And finally, although the mouse can be infected with the SARS-CoV-2, is it plausible that it could transmit the virus to other animals? Or worse yet, people? This fact is critical for proper risk assessment, although the authors recognize an answer may not be apparent. The scenario in which a mouse may escape the facility and become the murine analogue of “Typhoid Mary” of SARS-CoV-2 appear infinitesimal, and this should become apparent through a thorough risk assessment. The findings of this risk assessment should be noted in the MOU between the two institutions.
