Predictors of Switching Anti-Tumor Necrosis Factor Therapy in Patients with Ankylosing Spondylitis.

ABSTRACT: The aim of this study was to investigate the potential predictors of switching tumor necrosis factor (TNF)-? inhibitors in Korean patients with ankylosing spondylitis (AS). The patients who had been treated with TNF-? inhibitors were divided into two groups depending on whether they had switched TNF-? inhibitors. Demographic, clinical, laboratory, and treatment data at the time of initiation of TNF-? inhibitor treatment were compared between switchers and non-switchers, and within switchers according to the reasons for switching. Of the 269 patients, 70 (23%) had switched TNF-? inhibitors once; of these, 11 switched again. The median follow-up time was 52.7 months. Three- and five-year drug survival rates were 52%/48% for infliximab, 62%/42% for etanercept, and 71%/51% for adalimumab, respectively. Switchers were more likely to be prescribed disease-modifying anti-rheumatic drugs than non-switchers. A history of joint surgery and complete ankylosis of the sacroiliac joint was more frequent in switchers. Multivariate Cox's proportional hazard analysis showed that the use of adalimumab as the first TNF-? inhibitor was less likely to lead to switching and complete ankylosis of the sacroiliac joints was more likely to lead to switching. The principal reasons for switching were drug inefficacy and adverse events, but the differences in the clinical data of these two groups of switchers were not significant. In AS patients who are candidates for TNF-? inhibitor therapy, switching may improve the therapeutic outcome based on clinical information.

Project description:This study aims to investigate the prevalence of short-term and long-term adverse events associated with tumor necrosis factor-α (TNF-α) blocker treatment in Chinese Han patients suffering from ankylosing spondylitis (AS).The study included 402 Chinese Han AS patients treated with TNF-α blockers. Baseline data was collected. All patients were monitored for adverse events 2 hours following administration. Long-term treatment was evaluated at 8, 12, 52 and 104 weeks follow-up for 172 patients treated with TNF-α blockers.Short-term adverse events occurred in 20.15% (81/402), including rash (3.5%; 14/402), pruritus (1.2%; 5/402), nausea (2.2%; 9/402), headache (0.7%; 3/402), skin allergies (4.0%; 16/402), fever (0.5%; 2/402), palpitations (3.0%; 12/402), dyspnea (0.5%; 2/402), chest pain (0.2%; 1/402), [corrected] abdominal pain (1.0%; 4/402), hypertension (2.2%; 9/402), papilledema (0.5%; 2/402), laryngeal edema (0.2%; 1/402) and premature ventricular contraction (0.2%; 1/402). Long-term adverse events occurred in 59 (34.3%; 59/172) patients, including pneumonia (7.6%; 13/172), urinary tract infections (9.9%; 17/172), otitis media (4.7%; 8/172), tuberculosis are (3.5%; 6/172) [corrected], abscess (1.2%; 2/172), oral candidiasis (0.6%; 1/172), elevation of transaminase (1.7%; 3/172), anemia (1.2%; 2/172), hematuresis (0.6%; 1/172), constipation (2.3%; 4/172), weight loss (0.6%; 1/172), exfoliative dermatitis (0.6%; 1/172). CRP, ESR and disease duration were found to be associated with an increased risk of immediate and long-term adverse events (P<0.05). Long-term treatment with Infliximab was associated with more adverse events than rhTNFR-Fc (P<0.01).This study reports on the prevalence of adverse events in short-term and long-term treatment with TNF-α blocker monotherapy in Chinese Han AS patients. Duration of disease, erythrocyte sedimentation rate, and c-reactive protein serum levels were found to be associated with increased adverse events with anti-TNF-α therapy. Long-term treatment with Infliximab was associated with more adverse events than rhTNFR-Fc.

Project description:IntroductionTumor necrosis factor (TNF) antagonists reduce the signs and symptoms of spondyloarthritides, including ankylosing spondylitis (AS) and psoriatic arthritis (PsA). Our objective was to evaluate the effectiveness and safety of adalimumab, 40 mg every other week, for patients with AS or PsA and prior treatment with infliximab (IFX) and/or etanercept (ETN).MethodsBoth trials were 12-week, open-label studies with an optional extension period up to week 20. Patients were stratified by history of anti-TNF treatment, prior anti-TNF therapy received (IFX, ETN, or both), and reason for discontinuation of prior TNF antagonist. ETN was discontinued>or=3 weeks, and IFX was discontinued>or=2 months before the first adalimumab administration. Effectiveness at week 12 was evaluated by using observed standard-outcome measurements for AS and PsA.ResultsAt week 12 of adalimumab treatment, Bath Ankylosing Spondylitis Disease Activity Index 50 responses were achieved by 40.8% of 326 patients with AS who had received prior anti-TNF therapy and by 63.0% of 924 patients with AS who were naive to TNF antagonist. Observed response rates were generally greater for patients who discontinued the prior anti-TNF therapy because of loss of response or intolerance than for patients who discontinued because of lack of response. Median changes in swollen-joint count and in enthesitis score were similar in patients with and without prior TNF-antagonist treatment. Modified PsA response criteria were fulfilled by 71.2% of 66 patients with PsA, with prior exposure to TNF antagonists, and by 78.8% of 376 patients with no history of anti-TNF therapy. The percentages of patients with PsA attaining a Physician's Global Assessment of psoriasis of "Clear/Almost clear" increased from 33.3% to 61.0% for patients with prior IFX and/or ETN treatment and from 34.6% to 69.7% for patients without anti-TNF therapy. The median change in the Nail Psoriasis Severity Index was -6 for both groups. In both studies, patterns of adverse events were similar for patients with and without prior anti-TNF therapy and were consistent with the known safety profile of adalimumab.ConclusionsPatients with AS or PsA previously treated with IFX and/or ETN experienced clinically relevant improvements of their diseases after 12 weeks of adalimumab.Trial registrationsClinicalTrials.gov NCT00478660 and NCT00235885.

Project description:ImportanceTumor necrosis factor inhibitors (TNFis) have revolutionized the management of ankylosing spondylitis (AS); however, the lack of notable clinical responses in approximately one-half of patients suggests important heterogeneity in treatment response. Identifying patients likely to respond or not respond to TNFis could provide opportunities to personalize treatment strategies.ObjectiveTo develop models of the probability of short-term response to TNFi treatment in individual patients with active AS.Design, setting, and participantsThis is a retrospective cohort study using data of the TNFi group (ie, treatment group) from 10 randomized clinical trials (RCTs) of TNFi treatment among patients with active AS, conducted from 2002 to 2016. Participants were adult patients with active AS who failed nonsteroidal anti-inflammatory drugs. Included RCTs were phase 3 and 4 studies that assessed the efficacy of an originator TNFi at week 12 and/or week 24, either compared with placebo or an antirheumatic drug. The cohort was divided into a training and a testing set. Data analysis was conducted from July 1, 2019, to November 30, 2020.ExposuresAll included patients received an originator TNFi for at least 12 weeks.Main outcomes and measuresOutcomes included major response and no response based on the change of AS Disease Activity Score at 12 weeks. Machine learning algorithms were applied to estimate the probability of having major response and no response for individual patients.ResultsThe study included 1899 participants from 10 trials. The training set included 1207 individuals (mean [SD] age, 39 [12] years; 908 [75.2%] men), of whom 407 (33.7%) had major response and 414 (34.3%) had no response. In the reduced logistic regression models, accuracy was 0.74 for major response and 0.75 for no response. The probability of major response increased with higher C-reactive protein (CRP) level, patient global assessment (PGA), and Bath AS Disease Activity Index (BASDAI) question 2 score and decreased with higher body mass index (BMI) and Bath AS Functional Index (BASFI) score. The probability of no response increased with age and BASFI score, and decreased with higher CRP level, BASDAI question 2 score, and PGA. In the testing set (692 participants; mean [SD] age, 38 [11] years; 533 [77.0%] men), models demonstrated moderate to high accuracy.Conclusions and relevanceIn this cohort study, the probability of initial response to TNFi was predicted from baseline variables, which may facilitate personalized treatment decision-making.

Project description:To study the effect of tumor necrosis factor ? (TNF?) inhibitors on progressive spinal damage in patients with ankylosing spondylitis (AS).All AS patients meeting the modified New York criteria who had been monitored prospectively and had at least 2 sets of spinal radiographs a minimum of 1.5 years apart were included in the study (n=334). The patients received standard therapy, which included nonsteroidal antiinflammatory drugs and TNF? inhibitors. Radiographic severity was assessed by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Patients with a rate of AS progression that was ?1 mSASSS unit/year were considered progressors. Univariable and multivariable regression analyses were done. Propensity score matching and sensitivity analysis were performed. A zero-inflated negative binomial (ZINB) model was used to analyze the effect of TNF? inhibitors on the change in the mSASSS with varying followup periods. Potential confounders, such as disease activity (as assessed by the Bath Ankylosing Spondylitis Disease Activity Index), the erythrocyte sedimentation rate, C-reactive protein level, HLA-B27 positivity, sex, age at onset, smoking burden (number of pack-years), and baseline damage, were included in the model.TNF? inhibitor treatment was associated with a 50% reduction in the odds of progression, with an odds ratio (OR) of 0.52 (95% confidence interval [95% CI] 0.30-0.88, P=0.02). Patients with a delay of >10 years in starting therapy were more likely to experience progression as compared to those who started earlier (OR 2.4 [95% CI 1.09-5.3], P=0.03). In the ZINB model, the use of TNF? inhibitors significantly reduced disease progression when the gap between radiographs was >3.9 years. The protective effect of TNF? inhibitors was stronger after propensity score matching.Treatment with TNF? inhibitors appears to reduce radiographic progression in AS patients, especially with early initiation and with longer duration of followup.

Project description:ObjectTo investigate the factors associated with cause-specific discontinuation of long-term anti-tumor necrosis factor (TNF) agent use in patients with ankylosing spondylitis (AS).MethodsAS patients who initiated first-line anti-TNF treatment between 2004 and 2018 and continued treatment for at least two years were enrolled in the study. Enrolled patients were observed until the last visit, discontinuation of treatment, or September 2022. Reasons for discontinuation of the first-line anti-TNF agent were categorized into the following: (1) clinical remission, (2) loss of efficacy, (3) adverse events, and (4) other reasons including loss to follow-up, cost, or reimbursement issues. A cumulative incidence function curve was used to visualize the cumulative failure rates over time for each specific reason. Univariable and multivariable cause-specific hazard models were utilized to identify factors associated with cause-specific discontinuation of the first-line anti-TNF agent.ResultsA total of 429 AS patients was included in the study, with 121 treated with adalimumab (ADA), 176 with etanercept (ETN), 89 with infliximab (INF), and 43 with golimumab (GLM). The median overall survival on the first-line anti-TNF agent was 10.6 (7.9-14.5) years. Among the patients, 103 (24.0%) discontinued treatment, with 36 (34.9%) due to inefficacy, 31 (30.1%) due to clinical remission, 15 (14.6%) due to adverse events, and 21 (20.4%) due to other reasons. Patients treated with ETN had a lower risk of discontinuation due to clinical remission compared to those receiving ADA (hazard ratio [HR] 0.45 [0.21-0.99], P = 0.048). Higher baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI; HR 1.31 [1.04-1.65], P = 0.023) and INF use were linked to a higher risk of treatment discontinuation for inefficacy compared to ADA use (HR 4.53 [1.45-14.16], P = 0.009). Older age was related to an increased risk of discontinuation due to infection-related adverse events (HR 1.07 [1.02-1.12], P = 0.005), and current smoking was a risk factor for discontinuation due to other reasons (HR 6.22 [1.82-21.28], P = 0.004).ConclusionAS patients on their first anti-TNF treatment for at least two years demonstrated a favorable long-term treatment retention rate, with a 24.0% discontinuation rate over a 10.6-year overall survival period. The predictors for discontinuation varied by causes, underscoring the complexity of treatment response and the importance of personalized approaches to treatment management.
