Session Title: Spondyloarthritis Including Psoriatic Arthritis – Clinical Poster III: Treatment

Session Type: ACR Poster Session C

Session Time: 9:00AM-11:00AM

Background/Purpose:

Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL-17A, has demonstrated efficacy for patients with psoriatic arthritis (PsA) in multiple phase 3 clinical trials.1–4 To improve and standardize the assessment of PsA outcomes, the PsA core domain set, initially implemented in 2006,5 has been updated by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and endorsed by Outcome Measures in Rheumatology (OMERACT)6 in 2016. The updated PsA core domains are: musculoskeletal disease activity (arthritis, enthesitis, dactylitis, and spine symptoms), skin disease activity (psoriasis and nail psoriasis), pain, patient global assessment, physical function, fatigue, health-related quality of life, and systemic inflammation; structural damage assessment is recommended at least once in the development program of PsA medications. Here we report the efficacy of secukinumab vs placebo across individual PsA core domains, using pooled data from 4 phase 3 FUTURE studies.

Methods:

Patients with active PsA participated in the phase 3 clinical trials FUTURE 2, 3, 4, and 5 (397, 414, 341, and 996 patients, respectively).1–4 Data were pooled from the studies using secukinumab dosed at 150 mg (load vs no load), 300 mg, or placebo at the end of the 16-week double-blind period, and efficacy evaluated according to the updated GRAPPA-OMERACT PsA core domains. Core domains were assessed using multiple instruments (Table 1) with improvement defined as percentage of patients achieving ≥ 50% improvement (joints), complete resolution (arthritis, enthesitis, dactylitis), or minimal clinically important difference in PsA where known and/or least squares mean change from baseline (patient-reported outcomes). Axial data are from MEASURE 2 (not assessed in FUTURE studies).

Results:

2049 patients were included, of whom 461 received secukinumab 300 mg, 572 received secukinumab 150 mg, 335 received secukinumab 150 mg no load, and 681 received placebo.  Baseline demographics and disease characteristics were broadly similar in all treatment groups.  Efficacy results for each core domain are provided in Table 1.

Conclusion:

Secukinumab demonstrated efficacy across GRAPPA-OMERACT PsA core domains in the phase 3 clinical trials program using multiple instruments and thresholds to measure improvement. Secukinumab 300 mg had the greatest efficacy across domains vs placebo. Our results indicate that secukinumab improves both the disease manifestations and life impact of PsA as demonstrated using the PsA core domain set.
