Background Ankylosing spondylitis is a chronic immune-mediated infl ammatory disease characterised by spinal infl ammation, progressive spinal rigidity, and peripheral arthritis. Interleukin 17 (IL-17) is thought to be a key infl ammatory cytokine in the development of ankylosing spondylitis, the prototypical form of spondyloarthritis. We assessed the effi cacy and safety of the anti-IL-17A monoclonal antibody secukinumab in treating patients with active ankylosing spondylitis. Methods We did a randomised double-blind proof-of-concept study at eight centres in Europe (four in Germany, two in the Netherlands, and two in the UK). Patients aged 18-65 years were randomly assigned (in a 4:1 ratio) to either intravenous secukinumab (2 × 10 mg/kg) or placebo, given 3 weeks apart. Randomisation was done with a computergenerated block randomisation list without a stratifi cation process. The primary effi cacy endpoint was the percentage of patients with a 20% response according to the Assessment of SpondyloArthritis international Society criteria for improvement (ASAS20) at week 6 (Bayesian analysis). Safety was assessed up to week 28. This study is registered with ClinicalTrials.gov, number NCT00809159. Findings 37 patients with moderate-to-severe ankylosing spondylitis were screened, and 30 were randomly assigned to receive either intravenous secukinumab (n=24) or placebo (n=6). The fi nal effi cacy analysis included 23 patients receiving secukinumab and six patients receiving placebo, and the safety analysis included all 30 patients. At week 6, ASAS20 response estimates were 59% on secukinumab versus 24% on placebo (99•8% probability that secukinumab is superior to placebo). One serious adverse event (subcutaneous abscess caused by Staphylococcus aureus) occurred in the secukinumab-treated group. Interpretation Secukinumab rapidly reduced clinical or biological signs of active ankylosing spondylitis and was well tolerated. It is the fi rst targeted therapy that we know of that is an alternative to tumour necrosis factor inhibition to reach its primary endpoint in a phase 2 trial. Funding Novartis.

ObjectiveThis study aimed to report end-of-study results on efficacy and safety of secukinumab 150 mg through 5 years in patients with ankylosing spondylitis (AS; MEASURE 1 extension trial (NCT01863732)).MethodsAfter the 2-year core trial, 274 patients receiving subcutaneous secukinumab 150 or 75 mg (following intravenous loading or initial placebo treatment to 16/24 weeks) every 4 weeks were invited to enter the 3-year extension study. Dose escalation from 75 to 150 mg (approved dose) was allowed at or after week 156 based on the judgement of the treating physician. Assessments at week 260 (5 years) included Assessment of SpondyloArthritis international Society (ASAS) 20/40 and other efficacy outcomes. Data are presented as observed. Safety assessment included all patients who received ≥1 dose of study treatment.ResultsOf the 274 patients who entered the extension study, 84% (230/274) completed 5 years of treatment. ASAS20/40 responses were 78.6/65.2%, Bath Ankylosing Spondylitis D...

To evaluate the effect of secukinumab (interleukin-17A inhibitor) on patient-reported outcomes (PROs) in patients with active ankylosing spondylitis (AS). In this phase 3 study, 371 patients received (1:1:1) intravenous secukinumab 10 mg/kg (baseline, weeks 2 and 4) followed by subcutaneous secukinumab 150 mg (IV→150 mg) or 75 mg (IV→75 mg) every 4 weeks or placebo. PROs included Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), BASDAI 50, short form-36 (SF-36) Physical (PCS) and Mental Component Scores (MCS), AS quality of life (ASQoL), Bath Ankylosing Spondylitis Functional Index (BASFI), EuroQoL-5-dimension health status questionnaire (EQ-5D), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), and Work Productivity and Activity Impairment-General Health questionnaire (WPAI-GH). At week 16, secukinumab IV→150 mg or IV→75 mg was associated with statistically and clinically significant improvements from baseline versus placebo in BASDAI (-2.3 for both reg...

Secukinumab improved the signs and symptoms of ankylosing spondylitis (AS) over 52 weeks in the phase III MEASURE 2 study. Here, we report longer-term (104 weeks) efficacy and safety results. Patients with active AS were randomized to subcutaneous secukinumab 150 mg, 75 mg, or placebo at baseline; weeks 1, 2, and 3; and every 4 weeks from week 4. The primary end point was the Assessment of SpondyloArthritis international Society criteria for 20% improvement (ASAS20) response rate at week 16. Other end points included ASAS40, high-sensitivity C-reactive protein, ASAS5/6, Bath Ankylosing Spondylitis Disease Activity Index, Short Form 36 health survey physical component summary, ASAS partial remission, EuroQol 5-domain measure, and Functional Assessment of Chronic Illness Therapy fatigue subscale. End points were assessed through week 104, with multiple imputation for binary variables and a mixed-effects model repeated measures for continuous variables. Of 219 randomized patients, 60 o...

Secukinumab treatment has previously been shown to significantly improve the signs and symptoms of active ankylosing spondylitis (AS), with responses sustained through 2 years. Here, we report the long-term (3 years) efficacy and safety of secukinumab in the MEASURE 2 study. MEASURE 2 (NCT01649375) is a 5-year phase III, randomised, double-blind, double-dummy, parallel-group, placebo-controlled study to evaluate the efficacy, safety and tolerability of subcutaneous loading and maintenance dosing of secukinumab in adult subjects with active AS. Subjects were randomised to receive subcutaneous secukinumab 150 mg, 75 mg or placebo at baseline, weeks 1, 2 and 3 and every 4 weeks from week 4. At week 16, placebo-treated subjects were rerandomised to receive secukinumab 150/75 mg. Retention rates were high during weeks 16-156 and were 86% and 76% for secukinumab 150 and 75 mg, respectively. Secukinumab 150 mg provided sustained improvements in the Assessment of Spondyloarthritis Internati...

There is significant unmet need in patients with ankylosing spondylitis (AS) who have inadequate response or intolerance to anti-tumour necrosis factor (TNF) treatment. Secukinumab, an anti-interleukin-17A monoclonal antibody, significantly improved signs and symptoms of AS in the MEASURE 2 study (NCT01649375). Subjects with active AS (N=219) received secukinumab (150 or 75 mg) or placebo at baseline, weeks 1, 2, 3 and 4, and every 4 weeks thereafter. Randomisation was stratified by prior anti-TNF use: anti-TNF-naive or inadequate response/intolerance to one anti-TNF (anti-TNF-IR). The primary endpoint was Assessment of SpondyloArthritis International Society criteria (ASAS) 20 at week 16. At week 16, 68.2% of anti-TNF-naive subjects treated with secukinumab 150 mg achieved ASAS20 compared with 31.1% treated with placebo (p<0.001). In the anti-TNF-IR group, 50.0% of subjects treated with secukinumab 150 mg achieved an ASAS20 response compared with 24.1% treated with placebo (p<...

Introduction: Despite of higher disease burden, lower efficacy to biologics has been reported in female compared to male patients with ankylosing spondylitis (AS). The aim of this study was to evaluate the efficacy and safety of secukinumab by sex in patients with active AS from five phase 3 studies (MEASURE 1-5) through 52 weeks. Methods: Baseline demographics, disease characteristics and efficacy outcomes at Weeks 16 and 52 were summarized for males versus females. Baseline predictor analysis used multivariable logistic regression for binary outcome measures or generalized linear model for continuous outcome measures to assess the impact of sex as one of the independent variables on selected efficacy outcomes at Week 52. Results: Overall, 1031 males and 396 females were included in this analysis. Smoking status, hs-CRP, prior exposure to TNF inhibitors, BASMI occiput-to-wall and tragus-to-wall distance (cm) were higher in males, whereas MASES was higher in females. Efficacy outcomes i.e., ASAS40 responses and BASDAI change from baseline at Weeks 16 and 52 were generally comparable between males and females. Response rates were found to be significantly higher in male patients when compared with

Clinical research is needed to identify patients with axial spondyloarthritis (axSpA) who are more likely to be responsive to interleukin (IL)-17 inhibition. To evaluate short-term efficacy of secukinumab in the management of axSpA. Twenty-one patients (7 males, 14 females) with axSpA were consecutively treated with secukinumab. Laboratory and clinical assessments were based on erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Ankylosing Spondylitis Disease Activity Score (ASDAS)-CRP, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Data were recorded at baseline and at a 3 month follow-up visit. The study was comprised of 21 patients. Both BASDAI and ASDAS-CRP showed a statistically significant reduction between the baseline and the 3 month visit (P < 0.0001 and P = 0.0005, respectively). During the laboratory assessment, ESR showed a significant decrease (P = 0.008) while CRP improvement did not reach statistical significance (P = 0.213). No statis...
