  • The phase 3 PREVENT trial evaluated the efficacy of SEC in patients with nr-axSpA, and met the primary endpoint (ASAS40 at week 16), with a safety profile that was consistent with previous reports.

Non-radiographic axial spondyloarthritis (nr-axSpA) and ankylosing spondylitis (AS) are considered part of the spectrum of axSpA. Patients are classified as nr-axSpA due to the absence of definitive radiographic sacroiliitis, but suffer from similar disease burden as those with AS. NSAIDs are first-line therapy, and only one anti-TNF therapy is approved in the US for nr-axSpA pts with objective signs of inflammation. [1] Secukinumab (SEC) provides significant and sustained improvement in signs and symptoms of patients with AS2. [2] PREVENT is the first phase 3 study evaluating the efficacy and safety of SEC 150 mg with (LD) or without loading (NL) in patients with nr-axSpA.

  • To assess efficacy and safety of secukinumab in patients with nr-axSpA.
  • This phase 3, double blind, placebo (PBO)-controlled, multicenter trial included 555 pts (aged ≥18 years) fulfilling the ASAS (Assessment of SpondyloArthritis International Society) classification criteria for axSpA but not the modified New York Criteria, plus abnormal C-reactive protein (CRP) and/or magnetic resonance imaging (MRI), with no radiographic changes in the sacroiliac joints.
  • Patients were randomized (1:1:1) to subcutaneous SEC 150 mg LD, 150 mg NL, or PBO.
  • The LD group received SEC 150 mg at baseline, weeks 1, 2, 3, and 4, and then every 4 weeks (q4wk) through week 52.
  • The NL group received SEC 150 mg at baseline and PBO at weeks 1, 2, and 3, and then SEC 150 mg q4wk starting at week 4.
  • Analysis used the Net Reclassification Index for binary and the Mixed Model for Repeated Measures for continuous variables.
  • Endpoints were analyzed according to a statistical hierarchy.

Primary outcome

  • The primary endpoint was ASAS40 response with SEC 150 mg LD in anti-TNF-naïve patients at week 16.
  • Secondary endpoints included ASAS40 response rates, total Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), BASDAI50, Bath Ankylosing Spondylitis Functional Index (BASFI), Short Form-36 physical component summary (SF-36 PCS), Ankylosing Spondylitis Quality of Life (ASQoL), and ASAS partial remission in the overall population.
  • 94.6% (150 mg LD), 96.2% (150 mg NL), and 94.1% (PBO) patients completed 24 weeks of treatment.
  • Demographic and baseline disease characteristics were comparable across groups.
  • The primary and all secondary endpoints were met.
  • At week 16, ASAS40 in anti-TNF-naïve pts was significantly higher in the SEC 150 mg LD group than PBO patients (Figure).
  • SEC 150 mg LD and NL also showed significant improvement vs. PBO in all secondary endpoints (BASDAI, BASDAI50, BASFI, sacroiliac joint edema on MRI, high sensitivity-CRP, ASAS partial remission) as well as physical function and quality of life.
  • Three cases of serious infections/infestations (0.8%), and 1 case of Crohn’s disease (0.3%) were reported with SEC.
  • No cases of esophageal candidiasis, major adverse cardiovascular events, malignancy or death were reported on any SEC dose up to week 20.
  • SEC 150 mg LD provided significant improvement in signs and symptoms of nr-axSpA through week 16.
  • The safety profile of SEC was consistent with the established safety profile across indications

Key messages/Clinical perspectives

  • PREVENT is the first randomized controlled trial evaluating the efficacy and safety of SEC in patients with nr-axSpA, met the primary endpoint (ASAS40 at week 16) and confirmed the good safety profile of SEC
