Opportunistic infections associated with Janus kinase inhibitor treatment for rheumatoid arthritis: A structured literature review

Semin Arthritis RheumPublished Structured literature review of clinical trials

Authors' conclusion

HZ was the most common OI reported among RA patients using all currently approved JAK inhibitors in clinical trials, although tuberculosis and other OIs were also reported.

Main finding

As reported in the abstract

Opportunistic infections with JAKi in RA clinical trials
  • Highest exposure-adjusted incidence rate for herpes zoster (any form), followed by OI (any) and tuberculosis, based on limited data from trials with approved doses
  • Higher rates of opportunistic infections (OIs) in Asian and Australian populations vs the global population
  • Higher rates of OIs with increasing JAKi dose in most clinical trial data
  • Lack of head-to-head trials and differences in trial design preclude direct comparison across JAKi
