IRBs must comply with HHS and FDA regulations in 45 CFR part 46 and 21 CFR parts 50 and 56,
respectively, when reviewing research subject to those regulations. Both the HHS regulations at 45 CFR
§46.103(b)(4) and (5) and the FDA regulations at 21 CFR §56.108(a) and (b) state that IRBs must follow
written procedures to ensure that the IRB’s operations meet the applicable regulatory requirements.
Developing meaningful content for written procedures involves a comprehensive and critical assessment
of the IRB’s responsibilities, functions, and operations, and the institution’s organizational structure.
