description Background: Immunosuppression by biologic response modifiers (BRM) is a crucial component for successfulorgan transplantation. In addition to their variable effectiveness in the prevention of organ rejection,these medications have safety concerns that complicate therapeutic outcomes in organ transplantpatients.Objective: This study aims at identifying and characterizing safety signals of serious adverse events associatedwith exposure to BRM among organ transplant patients in a real-world environment.Methods: The FDA Adverse Event Reporting System was utilized to apply a pharmacovigilance disproportionalityanalysis to indentify serious adverse events. Associations between drugs and events weremeasured by empirical Bayes geometric mean (EBGM) and the corresponding 95% confidence intervals(EB05–EB95). Associations with EBGM≥2 were considered significant safety signals.Results: From 1997 to 2012, a total of 12,151 serious adverse event reports for BRM were reported; 15.6%of them (n=1,711) met the safety signal threshold of EB05>1, and 11.6% of these signals (n=199) weresignificant (EBGM≥2). Sirolimus and mycophenolate accounted for the majority of all signals; antithymocyteimmunoglobulin (ATI) and cyclosporine contributed to the majority of significant signals. The followingsignificant signals were identified for ATI (reduced therapeutic response, pulmonary edema, hypotension,serum sickness, infusion-related reaction, and anaphylactic reaction); for azathioprine (alternariainfection, fungal skin infection, and lymphoproliferative disorder); for cyclosporine (neurotoxicity,graft vs. host disease, and thyroid cancer); for cyclophosphamide (disease progression); for daclizumab(cytomegalovirus infection); and for tacrolimus (coma and tremor). 33.6% of these events contributedto patient death (n=67); 6.5% were life-threatening (n=13); 32.1% lead to hospitalization (n=64); and27.6% resulted in other serious outcomes (n=55).Conclusion: Utilization of BRM for the prophylaxis against transplant rejection is associated with seriousadverse events that could be fatal.
