New findings are unexpected problems whose nature, severity, and frequency are not
described in the information provided to the IRB or to participants. Examples include
unexpected complications in a subject, missteps in the consent documentation, or breaches
of confidentiality. Adverse events should be reported to the IRB within 10 calendar
days using the Subsequent Event Form and Guidelines found on the forms page. Sometimes a study must be suspended to ensure subjects' safety.
The report of the event should discuss:
the facts of the case, including the date and a description of the subject;
whether the event is related to the study's procedures or drugs or to the subject's
underlying disease or condition;
the steps that have been taken to address the problem;
whether the event is likely to recur; and whether the event provides new information

The University's policies on adverse events are based on Food and Drug Administration
regulations. According to the FDA, a "serious adverse drug experience" with respect
to human clinical experience includes "any experience that suggests a significant
hazard, contraindication, side effect, or precaution," including "any experience that
is fatal or life-threatening, is permanently disabling, requires inpatient hospitalization,
or is a congenital anomaly, cancer, or overdose." An "unexpected adverse experience"
is any adverse experience whose nature, severity, and frequency of risk are not described
in the information provided for IRB review or in the consent form.
