Relation entre le génotype et l'activité de la paraoxonase-1 et les événements cardiovasculaires indésirables majeurs ainsi que les tumeurs malignes, chez les patients atteints de polyarthrite rhumatoïde recevant du tofacitinib

High paraoxonase activity is associated with a significantly reduced risk of MACE and non-NMSC malignancies in white/European RA patients. The PON1 Q192R RR genotype had a significantly greater association with paraoxonase versus the QQ genotype, but had no significant association with MACE or non-NMSC malignancies.

In this post-hoc analysis by Schoeman, et al., data were pooled from three Phase 2 RCTs and six Phase 3 RCTs, which included two LTE studies. PON1 was a gene of interest as tofacitinib increases its activity levels.
