To gain knowledge into this rare and severe pathology we performed a study combining a pharmacovigilance approach and the pharmacodynamics properties of PKI.A disproportionality analysis on the WHO pharmacovigilance database using the Reporting Odds Ratio (ROR) and 95% confidence interval was first performed. Then, we identified the most relevant cellular targets of interest through a systematic literature review and correlated the pharmacovigilance signals with the affinity for the different PKI. We further performed a hierarchical cluster analysis to assess patterns of binding affinity.A positive disproportionality signal was found for dasatinib, bosutinib, ponatinib, ruxolitinib and nilotinib. Five non-receptor protein kinases significantly correlate with disproportionality signals: c-src (r=0.79 and p=0.00027), c-yes (r=0.82 and p=0.00015), Lck (r=0.81 and p=0.00046), Lyn (r=0.80 and p=0.00036), all belonging to the SRC protein kinase family; and TEC (r=0.85 and p=0.00006). Kinases of the BMP signalling pathway also seem to play a role in the pathophysiology of PKI-induced PAH. Interestingly, dasatinib affinity profile seems different from that of other PKIs in the cluster analysis.The study highlights potential role of SRC protein kinases family and TEC in PAH induced by PKI. This approach combining pharmacovigilance and pharmacodynamics data allowed us to generate some hypothesis about the pathophysiology of the disease, however the results have to be confirmed by further studies.FootnotesThis manuscript has recently been accepted for publication in the European Respiratory Journal.
