Spondyloarthritis & psoriatic arthritis

Effects of secukinumab on synovitis and enthesitis in patients with psoriatic arthritis: 52-week clinical and ultrasound results from the randomised, double-blind ULTIMATE trial with open label extension

Semin Arthritis RheumPublished Randomised controlled trial with open-label extension

Authors' conclusion

ULTIMATE showed consistent improvements in clinically and ultrasound-assessed synovitis and enthesitis and sustained clinical efficacy through week 52 in patients with PsA treated with secukinumab and placebo switched to secukinumab.

Study context

Population

Participants
166 patients
Comparison
Secukinumab 150 mg or 300 mg sc vs placebo to week 12, then all open-label secukinumab to week 52
Methodological detailsdouble-blind, placebo-controlled, Phase 3
  • Double-blind
  • Placebo-controlled
  • Phase 3

Primary result

As reported in the abstract

GLOESS (synovitis) · up to week 12
  • Significant reduction in GLOESS with secukinumab vs placebo at week 12; stable to week 52; placebo switchers reached a similar reduction at week 24, stable thereafter

Further findings

Spondyloarthritis Research Consortium of Canada (SPARCC) enthesitis index · up to week 12

Significant reduction with secukinumab vs placebo at week 12, sustained to week 52

Global OMERACT PDUS enthesitis score

Numerically lower with secukinumab vs placebo switchers in first two periods; some stability in third period in both groups

Clinical responses across key PsA domains · up to week 52

Improvements in both groups up to week 52
