Post-hoc analysis of two tofacitinib phase three studies concludes that tofacitinib treatment resulted in improvements in enthesitis in patients with PsA, regardless of baseline location or severity.

The results of a Bayesian network meta-analysis by Lee and Song showed that JAK inhibitors were more likely to achieve remission and LDA in DMARD-naive RA patients than MTX. However, there were no significant differences in remission rates nor LDA rates between the JAK inhibitors investigated.

This meta-analysis by Wei, et al. found that JAKi therapy was not associated with a higher risk of MACE than treatment with adalimumab, abatacept, or placebo. However, a higher incidence of all-cause mortality was observed with tofacitinib treatment than with adalimumab treatment.

Comparing the alignment of European national recommendations for patients with PsA and axSpA with EULAR and ASAS-EULAR treatment recommendations found that only a minority of national treatment recommendations were completely aligned.

Findings from a retrospective electronic data-based study, assessing risk of overall and site-specific malignancies for AS patients in Israel, emphasize the importance of maintaining the routine observation of patients with AS to identify the early development of cancer.

Three-year data from the ixekizumab (IXE) COAST programme provide additional evidence that patients with axSpA receiving IXE experience long-term safety, and sustained improvements in efficacy outcomes, at 3 years.

Phase IIb study of brepocitinib in patients with PsA concludes that treatment with brepocitinib 30 mg and 60 mg QD, was superior to placebo at reducing signs and symptoms of PsA and was well-tolerated over 52 weeks.

This study by Tanaka, et al. shows that filgotinib reduces peripheral protein biomarkers associated with JAK/STAT signalling, inflammatory signalling, immune cell migration, and bone resorption in RA patients. Notably, filgotinib 200 mg significantly reduced IL-6, TNF, CXCL13 levels as early as Week 4.

The data gathered in this post-marketing surveillance study aligned with the previously established safety profile of tofacitinib, and reports were found to have consistent safety profiles in the treatment of both patient with PsA and RA. However, the results of this study should be interpreted considering the limitations of post-marketing surveillance studies.

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.
