Multicenter Study of Secukinumab Uptitration in Axial Spondyloarthritis: Real-World Evidence

J RheumatolPublished Retrospective cohort study

Authors' conclusion

SEC uptitration to 300 mg was associated with sustained improvements in disease activity and favorable retention and safety in axSpA patients with active disease after receiving SEC 150 mg

Study context

Population
Patients with axial spondyloarthritis (axSpA) on SEC 150 mg for ≥ 3 months with active disease (ASDAS ≥ 2.1) at dose escalation; followed up to 24 months
Participants
106 patients
Exposure
SEC uptitration to 300 mg after active disease on SEC 150 mg
  • r-axSpAn = 77
  • nr-axSpAn = 29
Outcome
Change in ASDAS over time
Follow-up
Up to 24 months

Main finding

As reported in the abstract

Median ASDAS, before vs after escalation
  • Median ASDAS decreased from 4.1 to 2.0 in r-axSpA
  • Median ASDAS decreased from 4.1 to 2.0 in nr-axSpA
  • ASDAS significantly declined within 6 months and was sustained through 24 months

Observational data: associations, not effects.
