Investigator Warning Letter: Lapse in IRB Approval

In a recent investigator warning letter issued by the US Food and Drug Administration (FDA), an investigator was cited for failing to ensure an Institutional Review Board (IRB) that complies with the applicable regulatory requirements in 21 CFR 56 was overseeing their clinical trial. During the time where IRB approval for the protocol lapsed, the site continued to enroll and administer investigational products to study participants under that protocol. The investigator’s response to the FDA was inadequate because they explained that they did not need to report any adverse events during that timeframe.
