CITI: Reporting Serious Adverse Events
The sponsor must submit an IND Safety Report to the FDA if an adverse event is (1) serious; (2) unexpected; and:
(3) there is a reasonable possibility that the drug caused the event.
A double-blinded trial for a new indication is conducted under an IND comparing two (2) marketed drugs, at twice the approved prescribed doses. On Day 2, subject 603 had difficulty breathing. Although it was life-threatening initially, subject 603 was treated and discharged directly from the emergency department after complete recovery. On Day 5, subject 20 had a headache, which led to hospitalization and required blood pressure lowering medications. These episodes cannot be explained on the basis of the pharmacological property of either drug or the subjects' medical histories. The investigator would submit an SAE report for:
Both of the subjects
Subject 311 has had elevated white blood cell (WBC) counts for the past two (2) study visits, with no clinical signs or symptoms. "Increased WBC count" is not listed in the Investigator's Brochure (IB) as an adverse event. The investigator should:
Report the elevated WBC to the sponsor as an unexpected adverse event
During the course of administration of an investigational drug, the following events occurred: On Day 7, subject 603 had an unexpected stroke that requires hospitalization; On Day 15, subject 415 complained of nausea, vomiting, and headache relieved by aspirin; On Day 21, subject 20 has brief dizzy spells upon trying to stand. Which of these subject's events meets the FDA definition of "serious" and "unexpected" and would require the sponsor to file an IND Safety Report with the FDA?
