Baseline Characteristics and Treatment Response to Ixekizumab Categorised by Sex in Radiographic and Non-radiographic Axial Spondylarthritis Through 52 Weeks: Data from Three Phase III Randomised Controlled Trials.

ABSTRACT:

Objectives

Assess baseline characteristics and treatment response to ixekizumab (IXE) categorised by sex in patients with radiographic axial spondyloarthritis (r-axSpA) and non-radiographic axSpA (nr-axSpA) up to 52 weeks.

Methods

Data were analysed from three randomised controlled trials of IXE through 52 weeks. Patients fulfilled ASAS classification criteria for r-axSpA or nr-axSpA and were randomised to receive 80 mg subcutaneous administration of IXE every 2 weeks (Q2W) or 4 weeks (Q4W), or placebo (16 weeks COAST-V/W; 52 weeks COAST-X). Baseline characteristics and treatment outcomes were assessed. Patients were categorised by sex; methods included non-responder imputation for categorical variables, and modified baseline observation carried forward for continuous efficacy variables.

Results

At presentation, female patients had higher disease burden as reflected by significantly higher spinal pain at night, fatigue scores and pain/swelling in joints other than the neck, back or hip. ASAS40 response rate with the approved label dose, IXEQ4W, was achieved in 39% of male patients with r-axSpA by week 16, and 44% by week 52. For female patients, 16.7% and 33.3% achieved ASAS40 at week 16 and 52, respectively. In nr-axSpA, 46% of male patients achieved ASAS40 at week 16 and 30% at week 52. In total, 23.9% of female patients achieved ASAS40 at week 16, and 30.4% at week 52.

Conclusions

This analysis demonstrates that for the axSpA disease spectrum, female patients present with higher disease burden. Following treatment with IXE, there is a higher proportion of male responders up to 16 weeks, while female patients show less robust responses for the first 16 weeks but larger responses from weeks 16 through 52.

Project description:BackgroundPatients with non-radiographic axial spondyloarthritis experience negative impacts on sleep, work productivity, and activity impairment. Ixekizumab, a monoclonal antibody selectively targeting interleukin-17A, has shown efficacy in treating the signs and symptoms of non-radiographic axial spondyloarthritis. This analysis evaluated the effect of ixekizumab treatment on sleep, work productivity, and activity impairment in patients with non-radiographic axial spondyloarthritis.MethodsCOAST-X ( NCT02757352 ) was a 52-week, phase 3, multicenter, randomised placebo-controlled trial evaluating 80-mg ixekizumab every 2 weeks and every 4 weeks in patients with active non-radiographic axial spondyloarthritis. Sleep disturbance was measured with the Jenkins Sleep Evaluation Questionnaire (JSEQ) and analysed using mixed-effects models for repeated measures. Work productivity and activity impairment were measured using the Work Productivity and Activity Impairment Questionnaire for Spondyloarthritis and analysed using analysis of covariance. Absenteeism, presenteeism, and overall work impairment were assessed for patients reporting paid work; activity impairment was assessed regardless of work status.ResultsOverall, patients treated with both dosing regimens of ixekizumab reported numerically greater improvements in sleep than placebo through Week 52. At Weeks 16 and 52, patients treated with ixekizumab every 4 weeks had significantly greater improvements in presenteeism (p = 0.007 and p = 0.003, respectively) and overall work impairment (p = 0.014 and p = 0.005, respectively) and numeric improvements in absenteeism than placebo. Patients treated with ixekizumab every 2 weeks had numerically greater improvements in absenteeism, presenteeism, and overall work impairment than placebo. Both dosing regimens of ixekizumab were associated with significantly greater improvements in activity impairment than placebo (ixekizumab every 4 weeks: p = 0.003 at Week 16 and p = 0.004 at Week 52; ixekizumab every 2 weeks: p = 0.007 at Week 16 and p = 0.006 at Week 52).ConclusionsTreatment with ixekizumab improved sleep, work productivity, and activity impairment in patients with nr-axSpA. Improvements in presenteeism and overall work impairment were sustained and consistent in the patients treated with ixekizumab every 4 weeks from Week 16 to Week 52. Improvements in activity impairment were sustained and consistent in both ixekizumab-treated groups from Week 16 to Week 52.Trial registrationNCT02757352 , May 2, 2016.

Project description:BackgroundThis analysis assessed improvements in patients with radiographic axial spondyloarthritis (r-axSpA) treated with ixekizumab in the Assessment of Spondyloarthritis International Society (ASAS) treatment response domains and additional patient-reported outcomes at 1 year of treatment.MethodsCOAST-V and COAST-W were 52-week, phase 3, randomized controlled trials evaluating the efficacy and safety of ixekizumab in biologic disease-modifying antirheumatic drug (bDMARD)-naïve and tumor necrosis factor inhibitor (TNFi)-experienced patients with radiographic spondyloarthritis, respectively. Patients were treated with 80-mg ixekizumab either every 2 weeks or every 4 weeks. Patient-reported outcomes included Patient Global Disease Activity, Spinal Pain, stiffness as measured by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Questions 5 and 6, function as measured by the Bath Ankylosing Spondylitis Functional Index, fatigue as measured by the Fatigue Numeric Rating Scale and BASDAI question 1, Spinal Pain at Night, and sleep quality as measured by the Jenkins Sleep Evaluation Questionnaire. Mixed-effects models for repeated measures were used to analyze changes from baseline in patient-reported outcomes from weeks 1 to 16, and descriptive statistics were reported from weeks 20 to 52. Analysis of covariance with Scheffé's method was used for the ASAS response association analyses.ResultsThis study assessed 341 bDMARD-naïve and 316 TNFi-experienced patients in the placebo-controlled blinded treatment dosing period (weeks 1-16) as well as 329 bDMARD-naïve and 281 TNFi-experienced patients in the dose double-blind extended treatment period (weeks 20-52). bDMARD-naïve or TNFi-experienced patients treated with ixekizumab every 2 weeks and every 4 weeks reported improvements in patient global disease activity, spinal pain, function, stiffness, fatigue, spinal pain at night, and sleep quality through week 52. Greater correlations with improvements in all response domains were seen when comparing ASAS40 responders to ASAS20 non-responders (p < 0.001), with up to 10.5-fold greater improvements observed in ASAS40 responses compared with ASAS20 non-responders. Function and fatigue demonstrated the highest values.ConclusionsIxekizumab-treated bDMARD-naïve and TNFi-experienced patients with radiographic axial spondyloarthritis achieving ASAS40 reported sustained and consistent improvement in all ASAS response domains and other patient-reported outcomes though week 52, with spinal pain, function, and stiffness as major drivers of the response.Trial registrationNCT02696785 and NCT02696798 , March 2, 2016.

Project description:IntroductionA previous network meta-analysis established 16-week relative efficacy with bimekizumab, an inhibitor of interleukin (IL)-17F in addition to IL-17A, versus other treatments for patients with radiographic axial spondyloarthritis (r-axSpA; i.e., ankylosing spondylitis), including the IL-17A inhibitors secukinumab and ixekizumab. This matching-adjusted indirect comparison (MAIC) assessed 52-week relative efficacy of bimekizumab versus secukinumab and ixekizumab.MethodsIndividual patient data from BE MOBILE 2 (bimekizumab 160 mg; N = 220) were matched to pooled summary data from MEASURE 1/2/3/4 (secukinumab 150 mg), MEASURE 3 (secukinumab 300 mg; escalated dose for inadequate responders), COAST-V (ixekizumab) and COAST-V/-W (ixekizumab). BE MOBILE 2 patients were reweighted using propensity score weights based on age, sex, ethnicity, tumor necrosis factor inhibitor (TNFi) exposure, weight, baseline ASDAS and BASFI (secukinumab) and baseline BASDAI (ixekizumab), and 52-week efficacy outcomes from the trial recalculated. Odds ratios (OR) or mean difference for unanchored comparisons are reported with 95% confidence intervals (CI).ResultsAt week 52, MAIC demonstrated that patients may have higher likelihood of improvement in key efficacy outcomes with bimekizumab versus secukinumab 150 mg (e.g., ASAS40: [OR (95% CI): 1.48 (1.05, 2.10); p = 0.026]; effective sample size [ESS] = 177). Differences in 52-week efficacy outcomes between bimekizumab and secukinumab 300 mg dose escalation were non-significant (ESS = 120). Bimekizumab versus ixekizumab 80 mg comparisons (COAST-V only; ESS = 84) also suggested that differences were non-significant for most key efficacy outcomes. Other ixekizumab comparisons (COAST-V/-W; ESS = 45) suggested bimekizumab may have higher comparative efficacy for many of the same efficacy outcomes, however ixekizumab analyses were limited by poor population overlap, likely due to the greater proportion of patients with previous TNFi exposure.ConclusionsPatients treated with bimekizumab may have a higher likelihood of achieving improved longer-term efficacy versus secukinumab 150 mg, suggesting bimekizumab may be a favorable therapeutic option for r-axSpA. Differences in efficacy outcomes with bimekizumab versus ixekizumab 80 mg were mostly non-significant, depending on the populations considered.

Project description:Axial spondylarthritis (axSpA) is a progressive inflammatory condition that is treated with various management options. Interleukin-17A (IL-17A) inhibitors are a novel therapeutic option that demonstrates both efficacy and safety. This systematic review and meta-analysis evaluated the effectiveness of ixekizumab and its safety compared to a placebo. Medline, ScienceDirect, EBSCO, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched. We included randomized control trials (RCTs) that assessed the efficacy and safety of ixekizumab versus the placebo. The GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) assessment was utilized to evaluate the certainty of evidence. The revised Cochrane risk of bias tool for randomized trials was used to assess the risk of bias. Four RCTs (n=1016) met the eligibility criteria. All included studies had a low risk of bias. Significant improvements in the Assessment of Spondylarthritis International Society response for 40% improvement (ASAS40) (RR = 2.39, 95% CI 1.72-3.31, P < 0.01, I2 = 23%), Ankylosing Spondylitis Disease Activity Score (ASDAS) (SMD= -9.28 95% CI -12.31- (-6.25), P < 0.01, I2=97%), and Spondylarthritis Research Consortium of Canada (SPRACC score) (SMD= -5.82 95% CI -7.16- (-4.47), P < 0.01, I2=94%) were noted in comparison to placebo. Regarding safety, there was an insignificant increase in risk for serious adverse events (SAEs) (RR = 1.19, 95% CI 0.45-3.14, P = 0.73, I2 = 0%). Additionally, significant nonserious adverse events (NSAEs) (RR = 1.54, 95% CI 1.19-1.99, P = 0.001, I2 = 0%) were noted for the ixekizumab arm. No mortality events were detected in both arms. Ixekizumab, which demonstrates significant improvement in all efficacy endpoints, is a promising management option for axSpA patients who fail non-steroidal anti-inflammatory drugs (NSAIDs) therapy. However, the significant risk of developing adverse events hinders its utilization. More high-quality RCTs with larger sample sizes and prolonged follow-up periods are warranted to further assess this treatment option.

Project description:IntroductionPatients with ankylosing spondylitis (AS) are burdened with symptoms impacting work productivity measured by presenteeism, absenteeism, overall work impairment, and activity impairment. Ixekizumab, a high-affinity monoclonal antibody selectively targeting interleukin-17A, has been demonstrated to improve disease signs and symptoms in two phase 3 trials of AS. This study investigated for 52 weeks the effect of ixekizumab treatment on work productivity in patients with active AS.MethodsCOAST-V (NCT02696785) and COAST-W (NCT02696798) were phase 3, multicenter, randomized, controlled trials investigating the efficacy of ixekizumab 80 mg every 4 weeks (Q4W) and every 2 weeks (Q2W) in patients with AS naïve to biologic disease-modifying antirheumatic drugs (bDMARDs; COAST-V) or who were inadequate responders or intolerant to tumor necrosis factor inhibitors (TNFi; COAST-W). Work productivity was measured with the Work Productivity and Activity Impairment Questionnaire for Spondyloarthritis at weeks 16 and 52. Absenteeism, presenteeism, and overall work impairment were assessed for patients reporting paid work. Activity impairment was assessed regardless of work status.ResultsAt baseline, 66.2% (434/656) of patients reported paid work. At week 16, bDMARD-naïve patients treated with both ixekizumab dose regimens and TNFi-experienced patients treated with ixekizumab Q2W reported significant improvements in activity impairment (p < 0.01 and p < 0.05, respectively). TNFi-experienced patients treated with ixekizumab showed significant improvements versus placebo in presenteeism and overall work impairment (p < 0.05); bDMARD-naïve patients had numeric improvements. After week 16, patients initially on placebo switched to ixekizumab and patients already treated with ixekizumab continued treatment. Improvements in work productivity and daily activity were sustained through week 52 for both bDMARD-experienced and -naïve patients.ConclusionBoth bDMARD-naïve and TNFi-experienced patients with AS had greater improvements in work productivity and activity impairment when receiving ixekizumab compared to placebo at week 16. Improvements in work productivity and activity impairment achieved at week 16 were sustained through week 52 with ixekizumab treatment.

Project description:IntroductionIxekizumab, an interleukin-17A antibody, has shown efficacy in non-radiographic axial spondyloarthritis (nr-axSpA). The objectives of this analysis were (a) to measure improvement in ixekizumab-treated patients in Assessment of Spondyloarthritis International Society (ASAS) response domains and other patient-reported outcomes (PROs) and (b) to determine how ASAS responses were associated with changes in patient global disease activity (PtGA), spinal pain, function, stiffness, fatigue, and spinal pain at night.MethodsCOAST-X was a phase 3, 52-week multicenter, randomized, controlled trial investigating the efficacy and safety of 80-mg ixekizumab every 2 weeks (Q2W) and every 4 weeks (Q4W) in patients with active nr-axSpA. Changes from baseline in PROs were analyzed via mixed-effects models for repeated measures. Association analyses for ASAS responses used analysis of covariance with Scheffé's method.ResultsPatients treated with ixekizumab Q2W and Q4W reported significantly greater improvements in PtGA, spinal pain, function, and stiffness at week 1, when these measures were first assessed, compared with placebo (p < 0.05). ASAS40 responders, in comparison to ASAS20 non-responders, had the highest correlations with improvements in all response domains (PtGA, spinal pain, function, and stiffness) as well as fatigue and spinal pain at night (p < 0.001). ASAS40 responses were associated with 3.5- to 48.0-fold greater improvements in these PROs, with the highest values for PtGA and function, compared to ASAS20 non-achievement.ConclusionsAs early as week 1, patients with nr-axSpA treated with ixekizumab reported significant improvements in PtGA, spinal pain, function, and stiffness compared with those taking placebo. ASAS40 responders reported significantly greater improvements in all ASAS response domains (PtGA, spinal pain, function, and stiffness) as well as fatigue and spinal pain at night than ASAS20 non-responders. Improvements in PtGA and function appear to be major drivers in achieving ASAS40 response in patients with nr-axSpA.Trial registrationNCT02757352.
