7Agreement Between SMB and Blinded Psychiatrist
With Regard to Occurrence of Type 1 Events
19
- Concordance 90.5 (84 all)
- 2 possible explanations for discrepancies
- BP evaluation of Type 1 event was not subject to
challenge. All SMB determinations required
consensus of all 3 SMB members - SMB reviewed all PEP (n 577) whereas BP
assessed on average 8 - 9 PEPs (range (0 - 42)
less variability in reviewing PEP by SMB could be
expected - Primary endpoint, patients first SMB-determined
Type 1 event, prospectively defined and agreed
upon with FDA - High degree of agreement between SMB and BPs
regarding this endpoint confirms validity of
endpoint for demonstrating efficacy in patients
at risk for suicidal behavior
