Unexpected Adverse Event

Any adverse event occurring in one or more subjects in a research protocol, the nature, severity, or frequency of which is not consistent with either:                                  

  1. the known or foreseeable risk of AEs associated with the procedures involved in the research that are described in (a) the IRB-approved documents (e.g., applicable investigator brochure, current protocol narrative, current informed consent document), and (b) other relevant sources of information, such as product labeling and package inserts; or
  2. the expected natural progression of any underlying disease, disorder, or condition of the subject(s) experiencing the AE and the subject’s predisposing risk factor profile for the AE.
