A Fifty-Two-Week, Randomized, Placebo-Controlled Trial of Certolizumab Pegol in Nonradiographic Axial Spondyloarthritis.

ABSTRACT: OBJECTIVE:The natural history of nonradiographic axial spondyloarthritis (SpA) is incompletely characterized, and there are concerns that nonsteroidal antiinflammatory drugs provide inadequate disease control in patients with active disease. This study was undertaken to investigate the effects of certolizumab pegol (CZP), an anti-tumor necrosis factor treatment, in patients with nonradiographic axial SpA with objective signs of inflammation. METHODS:In this ongoing parallel-group double-blind study, adults with active disease were recruited from 80 centers in Australia, Europe, North America, and Taiwan, and were randomized 1:1 to receive placebo or CZP (400 mg at weeks 0, 2, and 4, followed by 200 mg every 2 weeks) in addition to nonbiologic background medication (NBBM). Switching to open-label CZP (or other biologic) or making background medication changes was permitted at any point during the trial, although changes before week 12 were discouraged. The primary end point was the proportion of patients achieving major improvement (MI) (i.e., a ?2.0-point decrease in the score from baseline or achievement of the lowest possible score [0.6]) in the Ankylosing Spondylitis Disease Activity Score (ASDAS) at week 52. RESULTS:A total of 317 patients were randomized to receive placebo plus NBBM (n = 158) or CZP plus NBBM (n = 159). ASDAS-MI at week 52 was achieved in 47.2% (75 of 159) of CZP plus NBBM patients, which was significantly greater (P < 0.0001) than the 7.0% (11 of 158) of placebo plus NBBM patients in whom ASDAS-MI was achieved. Of the placebo plus NBBM patients, 60.8% (96 of 158) switched to open-label treatment before week 52 compared to 12.6% (20 of 159) of the CZP plus NBBM patients. CONCLUSION:Adding CZP to background medication is superior to adding placebo in patients with active nonradiographic axial SpA. These results indicate that remission in nonradiographic axial SpA treated without biologics occurs infrequently, demonstrating the need for treatment beyond nonbiologic therapy.

Project description:Axial spondyloarthritis (SpA) is a chronic inflammatory disease characterized by back pain and stiffness. The objective of this study was to determine whether golimumab is superior to placebo in patients with nonradiographic axial SpA.This phase III, double-blind, randomized, placebo-controlled trial was performed to evaluate subcutaneous golimumab (50 mg) versus placebo in patients ages ?18 years to ?45 years who had active nonradiographic axial SpA according to the Assessment of SpondyloArthritis international Society (ASAS) criteria for ?5 years since diagnosis, high disease activity, and an inadequate response to or intolerance of nonsteroidal antiinflammatory drugs. Patients were randomized 1:1 to receive golimumab or placebo subcutaneously every 4 weeks. The primary end point was 20% improvement according to the ASAS criteria (ASAS20) at week 16. Key secondary end points were an ASAS40 response, ASAS partial remission, 50% improvement in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and change in the Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) index for sacroiliac (SI) joint inflammation (SPARCC score).Of the 198 patients randomized, 197 were treated (97 received golimumab, and 100 received placebo). The mean age of the patients was 31 years, and 57.1% were male. At baseline, the mean?±?SD BASDAI was 6.5?±?1.5, the mean?±?SD ASDAS was 3.5?±?0.9, and the mean?±?SD SPARCC score was 11.3?±?14.0. The primary end point, an ASAS20 response, was achieved by significantly more patients in the golimumab group compared with the placebo group (71.1% versus 40.0%; P < 0.0001). An ASAS40 response was also achieved by significantly more patients in the golimumab group compared with the placebo group (56.7% versus 23.0%; P < 0.0001). The incidence of adverse events did not differ meaningfully between groups.Patients with active nonradiographic axial SpA treated with golimumab had significantly greater improvement in symptoms compared with patients treated with placebo. Golimumab was well tolerated and had a favorable risk/benefit profile.

Project description:IntroductionAchievement of remission is a key treatment goal for patients with axial spondyloarthritis (axSpA). C-OPTIMISE assessed achievement of sustained clinical remission in patients with axSpA, including radiographic (r) and non-radiographic (nr) axSpA, during certolizumab pegol (CZP) treatment, and subsequent maintenance of remission following CZP dose continuation, dose reduction or withdrawal. Here, we report outcomes from the first 48 weeks (induction period) of C-OPTIMISE, during which patients received open-label CZP.MethodsC-OPTIMISE (NCT02505542) was a two-part, multicenter, phase 3b study in adult patients with early axSpA (r-/nr-axSpA), including a 48-week open-label induction period followed by a 48-week maintenance period. Patients with active adult-onset axSpA, < 5 years' symptom duration, and fulfilling Assessment of SpondyloArthritis international Society classification criteria, were included. During the induction period, patients received a loading dose of CZP 400 mg at weeks 0, 2, and 4, followed by CZP 200 mg every 2 weeks (Q2W) up to week 48. The main outcome of the 48-week induction period was the achievement of sustained clinical remission (defined as an Ankylosing Spondylitis Disease Activity Score [ASDAS] < 1.3 at week 32 and < 2.1 at week 36 [or vice versa], and < 1.3 at week 48).ResultsIn total, 736 patients (407 with r-axSpA, 329 with nr-axSpA) were enrolled into the study. At week 48, 43.9% (323/736) of patients achieved sustained remission, including 42.8% (174/407) of patients with r-axSpA and 45.3% (149/329) with nr-axSpA. Patients also demonstrated substantial improvements in axSpA symptoms, MRI outcomes and quality of life measures. Adverse events occurred in 67.9% (500/736) of patients, of which 6.0% (44/736) were serious.ConclusionsOver 40% of patients with early axSpA achieved sustained remission during 48 weeks of open-label CZP treatment. Additionally, patients across the axSpA spectrum demonstrated substantial improvements in imaging outcomes and quality of life following treatment. No new safety signals were identified.Trial registrationNCT02505542.

Project description:Patient-reported outcomes (PROs) provide an opportunity to collect important information relating to patient well-being, which is often difficult for physicians to measure (e.g., quality of life, pain, fatigue, and sleep). Here we evaluate the effects of certolizumab pegol (CZP) on PROs during the 24-week, double-blind phase of the RAPID axial spondyloarthritis (SpA) trial, a phase 3 trial of axial SpA patients, including both ankylosing spondylitis (AS) and nonradiographic axial SpA patients.A total of 325 patients with active axial SpA were randomized 1:1:1 to placebo, CZP 200 mg every 2 weeks, or CZP 400 mg every 4 weeks. The primary end point was the Assessment of SpondyloArthritis International Society criteria for 20% improvement in disease activity response at week 12, and has been reported previously. PROs included total back pain, nocturnal back pain, a daily pain diary, the Sleep Problems Index II (SPI) domain of the Medical Outcomes Study (MOS) Sleep Scale, fatigue, the Ankylosing Spondylitis Quality of Life (ASQOL) measure, and the Short Form 36-item (SF-36) health survey physical component summary (PCS), mental component summary (MCS), and domains.Patients treated with CZP reported significant improvements from week 1 for nocturnal back pain (placebo -0.6, CZP 200 mg every 2 weeks -1.9, and CZP 400 mg every 4 weeks -1.6; P < 0.001) and ASQOL (placebo -1.0, CZP 200 mg every 2 weeks -2.3, and CZP 400 mg every 4 weeks -1.9; P < 0.05) compared with placebo, while significant improvements in total back pain were seen from day 2. Patients treated with both CZP dosing regimens also had significantly greater improvements in fatigue, MOS-SPI, SF-36 PCS, MCS, and domains compared with placebo. Improvements were similar in both AS and nonradiographic axial SpA patients.Both CZP dosing schedules rapidly improved patient well-being, as measured by PROs, including pain, fatigue, sleep, SF-36, and ASQOL in both AS and nonradiographic axial SpA patients.

Project description:ObjectiveAxial spondyloarthritis (axial SpA) is characterized by inflammation of the spine and sacroiliac joints and can also affect extraarticular sites, with the most common manifestation being uveitis. Here we report the incidence of uveitis flares in axial SpA patients from the RAPID-axSpA trial, including ankylosing spondylitis (AS) and nonradiographic (nr) axial SpA.MethodsThe RAPID-axSpA (NCT01087762) trial is double-blind and placebo-controlled to week 24, dose-blind to week 48, and open-label to week 204. Patients were randomized to certolizumab pegol (CZP) or placebo. Placebo patients entering the dose-blind phase were re-randomized to CZP. Uveitis events were recorded on extraarticular manifestation or adverse event forms. Events were analyzed in patients with/without history of uveitis, and rates reported per 100 patient-years.ResultsAt baseline, 38 of 218 CZP-randomized patients (17.4%) and 31 of 107 placebo-randomized patients (29.0%) had past uveitis history. During the 24-week double-blind phase, the rate of uveitis flares was lower in CZP (3.0 [95% confidence interval (95% CI) 0.6-8.8] per 100 patient-years) than in placebo (10.3 [95% CI 2.8-26.3] per 100 patient-years). All cases observed during the 24-week double-blind phase were in patients with a history of uveitis; in these patients, rates were similarly lower for CZP (17.1 [95% CI 3.5-50.1] per 100 patient-years) than placebo (38.5 [95% CI 10.5-98.5] per 100 patient-years). Rates of uveitis flares remained low up to week 96 (4.9 [95% CI 3.2-7.4] per 100 patient-years) and were similar between AS (4.4 [95% CI 2.3-7.7] per 100 patient-years) and nr-axial SpA (5.6 [95% CI 2.9-9.8] per 100 patient-years).ConclusionThe rate of uveitis flares was lower for axial SpA patients treated with CZP than placebo during the randomized controlled phase. Incidence of uveitis flares remained low to week 96 and was comparable to rates reported for AS patients receiving other anti-tumor necrosis factor antibodies.

Project description:BackgroundIdentification of predictive clinical factors of long-term treatment response may contribute to improved management of non-radiographic axSpA (nr-axSpA) patients. This analysis aims to identify whether any baseline characteristics or Week 12 clinical outcomes in nr-axSpA patients with elevated C-reactive protein (CRP) and/or sacroiliitis on magnetic resonance imaging (MRI) enrolled in the C-axSpAnd study are predictive of achieving clinical response after 1 year of certolizumab pegol (CZP).MethodsC-axSpAnd (NCT02552212) was a phase 3, multicentre study, including a 52-Week double-blind, placebo-controlled period. Enrolled patients were randomised to CZP 200 mg Q2W or placebo. Predictors of Week 12 (CZP group only) and Week 52 clinical response were identified using a multivariate stepwise logistic regression analysis. Response variables included Ankylosing Spondylitis Disease Activity Score major improvement (ASDAS-MI), Assessment of SpondyloArthritis International Society 40% response (ASAS40), Bath Ankylosing Spondylitis Disease Activity Index 50% response (BASDAI50) and ASDAS inactive disease (ASDAS-ID). Predictive factors assessed included demographic and baseline characteristics and clinical outcomes at Week 12. A p-value <0.05 was required for forward selection into the model and p ≥0.1 for backward elimination. Missing data or values collected after switching to open-label treatment were accounted for using non-responder imputation. Sensitivity analyses accounted for patients with changes in non-biologic background medication.ResultsOf 317 enrolled patients, 159 and 158 were randomised to CZP and placebo, respectively. Younger age and male sex were identified as predictors of Week 12 response across all assessed efficacy outcomes in CZP-treated patients. Consistent predictors of Week 52 response, measured by ASDAS-MI, ASAS40 and BASDAI50, included human leukocyte antigen (HLA)-B27 positivity and sacroiliitis on MRI at baseline. MRI positivity was also predictive of achieving ASDAS-ID at Week 52. Sensitivity analyses were generally consistent with the primary analysis. In placebo-treated patients, no meaningful predictors of Week 52 response were identified.ConclusionsIn this 52-Week, placebo-controlled study in nr-axSpA patients with elevated CRP and/or active sacroiliitis on MRI at baseline, MRI sacroiliitis and HLA-B27 positivity, but not elevated CRP or responses at Week 12, were predictive of long-term clinical response to CZP. Findings may support rheumatologists to identify patients suitable for TNFi treatment.Trial registrationClinicalTrials.gov, NCT02552212 . Registered on 15 September 2015.

Project description:ObjectiveTo investigate the efficacy of 16-week treatment with etanercept (ETN) in patients with suspected nonradiographic axial spondyloarthritis (SpA).MethodsTumor necrosis factor inhibitor-naive patients with inflammatory back pain with at least 2 SpA features and high disease activity (Bath Ankylosing Spondylitis Disease Activity Index score ≥4), without the requirement of a positive finding on magnetic resonance imaging (MRI) of the sacroiliac (SI) joint and/or elevated C-reactive protein (CRP) level, were randomized (1:1) to receive ETN (n = 40) or placebo (n = 40) for 16 weeks and subsequently were followed up for a further 8 weeks (to 24 weeks from baseline) without study medication. The primary end point was the Assessment of SpondyloArthritis international Society 20 (ASAS20) response at 16 weeks. Secondary end points included the Ankylosing Spondylitis Disease Activity Score (ASDAS) and changes in disease parameters, including the Bath Ankylosing Spondylitis Metrology Index (BASMI), CRP level, erythrocyte sedimentation rate (ESR), and Spondyloarthritis Research Consortium of Canada index scores (MRI of the SI joint), after 16 and 24 weeks.ResultsPatient characteristics at baseline were comparable between the ETN and placebo groups. At 16 weeks, there was no significant difference in the percentage of patients exhibiting ASAS20 response between the ETN group (6 patients [16.7%]) and the placebo group (4 patients [11.1%]) (relative risk 0.7 [95% confidence interval 0.2-2.2], P = 0.5). Only the ESR showed more improvement in the ETN group compared to the placebo group at 16 weeks (decreases of 2.2 mm/hour and 1.4 mm/hour, respectively), but the difference did not reach statistical significance. Between 16 and 24 weeks, without study medication, the BASMI, CRP level, and ESR had worsened to a greater extent in the ETN group compared to the placebo group, with the difference being significant for the CRP level.ConclusionThis study shows that in patients with suspected nonradiographic axial SpA with high disease activity but without the requirement of a positive finding on SI joint MRI and/or elevated CRP level, treatment with ETN is not effective.
