OBJECTIVE: To describe baseline characteristics and to compare treatment effectiveness of secukinumab versus tumor necrosis factor inhibitors (TNFi), in patients with spondyloarthritis (SpA) using adalimumab as the main comparator.

METHODS: Observational, prospective cohort study. Patients with SpA (clinical ankylosing spondylitis/non-radiographic axial SpA/undifferentiated SpA) starting secukinumab or a TNFi during 2015-2018 were identified from five Nordic clinical rheumatology registries. Comorbidities and extra-articular manifestations (psoriasis/uveitis/inflammatory bowel disease) were captured from national registries (data available in 94% of patients) and included in multivariable analyses. We assessed 1-year treatment retention (crude survival curves, adjusted hazard ratios (HR) for treatment discontinuation) and 6-months' response-rates (ASDAS<2.1/BASDAI<40mm, crude/LUNDEX-adjusted, adjusted logistic-regression analyses with odds-ratio(OR)), stratified by line of biological treatment (1st /2nd /3rd +).

RESULTS: In total, 10,853 treatment courses (842 secukinumab/10,011 TNFi whereof 1,977 adalimumab) were included. The proportion treated with secukinumab during 1st /2nd /3rd + was 1%/6%/22%). Extra-articular manifestations varied across treatments, while other baseline characteristics were largely similar. Secukinumab had a one-year retention comparable to adalimumab as 1st or 2nd , but poorer as 3rd + line of therapy (secukinumab 56% (51%-61%) versus adalimumab 70% (64%-75%)), adjusted HR 1.43 (1.12-1.81). Across treatment lines, secukinumab had poorer estimates for 6-months response rates than adalimumab, statistically significantly so only for 3rd + line (adjusted analyses: ASDAS<2.1 OR=0.56 (0.35-0.90), BASDAI<40mm OR=0.62 (0.41-0.95)). Treatment outcomes varied across the five TNFi.

CONCLUSION: Secukinumab was mainly used in biologically experienced SpA patients. Secukinumab and adalimumab performed similar in patients who had failed a first biological, although with increasing prior biological exposure, adalimumab was superior.
