Rheumatoid arthritis

Comparison of anti-IL-6 receptor and JAK inhibitors in patients with rheumatoid arthritis from the real-world practice FIRST registry

Rheumatology (Oxford)Published Retrospective cohort study

Authors' conclusion

IL-6Ri offers a superior balance of efficacy and safety compared with JAKis for RA patients unresponsive to one bDMARD. However, JAKis may suit patients who do not respond to multiple bDMARDs.

Study context

Population
Patients with rheumatoid arthritis (RA) with inadequate response to biological disease-modifying antirheumatic drug (bDMARD), real-world FIRST registry
Exposure
JAKi vs IL-6Ri as second or subsequent molecular-targeted therapy
Outcome
CDAI remission rate
Follow-up
Week 26
Methodological detailsregistry-based (FIRST registry), propensity score-based inverse probability of treatment weighting, growth mixture modeling
  • Registry-based (FIRST registry)
  • Propensity score-based inverse probability of treatment weighting
  • Growth mixture modeling

Main finding

As reported in the abstract

CDAI remission
  • Remission rate higher with Janus kinase inhibitors (JAKis) than IL-6Ri
  • PS-IPTW

Observational data: associations, not effects.

Further findings

CDAI remission, failure of one bDMARD (subgroup) · week 26 · no significant difference

P = 0.21

Clinical disease activity index (CDAI) remission, failure of ≥2 bDMARDs (subgroup) · week 26

Remission rate higher with JAKis than IL-6Ri

Efficacy of IL-6Ri by number of failed bDMARDs

IL-6Ri greater efficacy after single vs multiple ineffective bDMARDs
CDAI trajectories divided into four by growth mixture modeling

Safety

Infection incidence

Higher with JAKis than IL-6Ri
