Abstract
Background:
The signal is defined as “reported information on a possible causal relationship
between an adverse event and a drug, of which the relationship is unknown or incompletely
documented previously”.
Objective:
To detect novel adverse events of iloperidone by disproportionality analysis in FDA
database of Adverse Event Reporting System (FAERS) using Data Mining Algorithms (DMAs).
Methodology:
The US FAERS database consists of 1028 iloperidone associated Drug Event
Combinations (DECs) which were reported from 2010 Q1 to 2016 Q3. We consider DECs for
disproportionality analysis only if a minimum of ten reports are present in database for the given
adverse event and which were not detected earlier (in clinical trials). Two data mining algorithms,
namely, Reporting Odds Ratio (ROR) and Information Component (IC) were applied retrospectively in
the aforementioned time period. A value of ROR-1.96SE>1 and IC- 2SD>0 were considered as the
threshold for positive signal.
Results:
The mean age of the patients of iloperidone associated events was found to be 44years [95%
CI: 36-51], nevertheless age was not mentioned in twenty-one reports. The data mining algorithms
exhibited positive signal for akathisia (ROR-1.96SE=43.15, IC-2SD=2.99), dyskinesia (21.24, 3.06),
peripheral oedema (6.67,1.08), priapism (425.7,9.09) and sexual dysfunction (26.6-1.5) upon analysis
as those were well above the pre-set threshold.
Conclusion:
Iloperidone associated five potential signals were generated by data mining in the FDA
AERS database. The result requires an integration of further clinical surveillance for the quantification
and validation of possible risks for the adverse events reported of iloperidone.
