Spondyloarthritis & psoriatic arthritis

Adherence to therapy of ixekizumab and secukinumab in psoriatic arthritis patients using first- or second-line IL-17A inhibitor treatment: a Danish population-based cohort study

Rheumatology (Oxford)Published Population-based cohort study

Authors' conclusion

PsA patients receiving first- or second-line IL-17A inhibitors showed homogeneous baseline characteristics and similar adherence to therapy.

Study context

Population
PsA patients in DANBIO, 2014–2021, previously treated with one or more TNFi, receiving first- or second-line IL-17A inhibitor
Participants
534 / 510 / 24 / 102 / 35 / 67
Exposure
First-line vs second-line IL-17A inhibitor treatment
  • First-line switchersn = 534reference
  • First-line secukinumabn = 510
  • First-line ixekizumabn = 24
  • Second-line switchersn = 102
  • Second-line secukinumabn = 35
  • Second-line ixekizumabn = 67

Main finding

As reported in the abstract

Adherence to therapy
  • First- and second-line switchers had a similar adherence to therapy
  • Second-line secukinumab and second-line ixekizumab switchers showed a similar adherence to treatment

Observational data: associations, not effects.

Further findings

Baseline characteristics

Similar HAQ and visual analogue scale (VAS) pain
VAS global, DAS28-CRP and previous number of bDMARDs similar, with a greater value for second-line switchers
First-line ixekizumab: younger age, more females, lower disease duration and lower CRP
Concomitant MTX use greater for first-line secukinumab
