OBJECTIVE: To assess the incidence of anti-drug antibodies (ADA) in patients with rheumatoid arthritis (RA) treated with the TNF inhibitors etanercept (ETN), adalimumab (ADL), or infliximab (IFX), and determine the potential relationship with trough drug concentration, efficacy, and patient-reported outcomes. METHODS: This multi-national, non-interventional, cross-sectional study (NCT01981473) enrolled adult patients with RA treated continuously for 6-24 months with ETN, ADL, or IFX...

BACKGROUND: To evaluate if TNF inhibitor serum drug levels (DL) or anti-drug antibodies (ADAb) can predict successful dose reduction (in patients with high DL) or discontinuation (in patients with no/low DL or ADAb) in rheumatoid arthritis (RA) patients. RESEARCH DESIGN AND METHODS: RA patients that were using adalimumab (n = 42), etanercept (n = 76) or infliximab (n = 51) and were doing well, were tapered until discontinuation or flare (1-1.5 year follow up)...

BACKGROUND: Monoclonal antibodies drugs directed against TNFα, TNFα inhibitors, are immunogenic, and consequent anti-drug antibodies (ADA) formation may decrease the functional drug concentration, resulting in a loss of response. We evaluated the impact of ADA on TNFα therapeutic response. METHODS: We considered studies enrolling adult patients affected by autoimmune inflammatory disease in therapy with TNFα inhibitors. We collected data about study and population characteristics, treatment dosage, determination of ADA and adverse events (AE)...

BACKGROUND AND AIMS: The aim of the study was to evaluate, if the strategy to stop anti-TNF treatment after determination of low trough serum levels and exclusion of inflammation is associated with lower relapse rates. METHODS: Since 2013 we followed an exit strategy in patients treated with anti-TNF treatment for inflammatory bowel disease based on trough serum levels. The relapse rates were observed prospectively, data analysis was performed in a retrospective manner of the collected clinical data...

A number of studies have attempted to elucidate the binding mechanism between tumor necrosis factor (TNF) and clinically relevant antagonists. None of these studies, however, have been conducted as close as possible to physiologic conditions, and so the relationship between the size distribution of TNF-antagonist complexes and the antagonists' biological activity or adverse effects remains elusive. Here, we characterized the binding stoichiometry and sizes of soluble TNF-antagonist complexes for adalimumab, infliximab, and etanercept that were formed in human serum and in phosphate-buffered saline (PBS)...

Ulcerative colitis (UC) is a relapsing-remitting chronic inflammatory disorder affecting the mucosal surface in a continuous manner from the rectum through part of, or the entire, colon. Patients with severe disease and those who become refractory or intolerant to corticosteroids and/or immunosuppressants, require treatment with biologic agents that target tumor necrosis factor-α (TNF). Golimumab, a fully human monoclonal antibody, is the latest TNF antagonist to get approved for the treatment of moderate-to-severe UC...

We longitudinally examined the influence of anti-tumor necrosis factor (TNF)-α treatment on serum levels of KL-6 and surfactant protein-D (SP-D). The study group comprised 22 patients with psoriasis treated with infliximab or adalimumab and with no history of interstitial lung disease (ILD). KL-6 and SP-D levels were measured in serum samples. Twelve of the 22 patients (55%) showed at least a 20% increase in KL-6 levels compared with baseline. Of these 12 patients, none exhibited any signs of ILD on chest computed tomography and nine who showed an increase in KL-6 levels (75%) showed at least a 20% increase in SP-D levels...

Objective.: The aim was to evaluate the predictive value of the baseline multi-biomarker disease activity (MBDA) score in long-standing RA patients with low disease activity tapering TNF inhibitors (TNFi) for successful tapering or discontinuation, occurrence of flare and major flare, and radiographic progression. Methods.: Dose REduction Strategies of Subcutaneous TNF inhibitors (Dutch Trial Register, NTR 3216) is an 18-month non-inferiority randomized controlled trial comparing tapering of TNFi until discontinuation or flaring with usual care (UC) in long-standing RA patients with stable low disease activity...

It has been reported that tuberculosis (TB) worsens after cessation of tumor necrosis factor-α inhibitors and starting anti-TB treatment. Little is known about the immunological pathogenesis of this paradoxical response (PR). We report the first case of a TB patient in whom PR occurred concurrently with elevation of circulating tumor necrosis factor-α (TNFα) levels. A 75-year-old woman, who had been treated with adalimumab for SAPHO syndrome, developed disseminated TB. Soon after administration of anti-TB treatment (isoniazid, rifampicin, pyrazinamide, and ethambutol), and after discontinuation of adalimumab, a PR occurred...

BACKGROUND: The 52-week safety and efficacy of adalimumab in Japanese patients with moderately to severely active ulcerative colitis were demonstrated in a placebo-controlled phase 2/3 trial. Data from patients who enrolled in the open-label extension study are presented. METHODS: Remission and response per the full Mayo score (FMS) and the partial Mayo score (PMS), remission per the Inflammatory Bowel Disease Questionnaire (IBDQ) score, corticosteroid-free remission, and mucosal healing were assessed up to week 196 (week 208 for remission/response per PMS) of adalimumab treatment in patients who received one or more doses of adalimumab with use of a hybrid nonresponder imputation (hNRI) method...

Golimumab (GLM) is the latest anti-tumor necrosis factor (TNF) that gained its marketing license. Thanks to the PURSUIT induction and maintenance trials, it was approved for the treatment of ulcerative colitis (UC) in 2013. The other anti-TNF drugs available are infliximab and adalimumab. These two drugs have validated algorithms concerning prescription and therapeutic drug monitoring (TDM) but little is known about GLM. The available data on GLM's exposure-response relationship in UC are from the PURSUIT trials and are recently published...

Patients treated with the TNF antagonist adalimumab develop anti-therapeutic antibodies (ATA), the prevalence of which varies depending on the assay used. Most assays are compromised due to the presence of adalimumab in the clinical samples. Our objective was to develop an antibody assay, applicable for clinical testing, which overcomes the limitation of therapeutic interference and to further determine the relationship between ATA development, adalimumab levels and disease activity in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS)...

BACKGROUND: Loss of response to anti-tumour necrosis factor (TNF) therapy in patients with inflammatory bowel disease (IBD) is often caused by anti-drug antibody formation with neutralisation of drug effect. Addition of an immunomodulator has been suggested to reduce immunogenicity, leading to regained response. AIM: To investigate whether addition of an immunomodulator to anti-TNF monotherapy could lead to anti-drug antibody suppression and regained clinical response in IBD patients...

BACKGROUND: Data on dose de-escalation in patients with Crohn's disease (CD) are limited. AIM: To evaluate outcomes of dose de-escalation from adalimumab (ADM) every other week (EOW) to every three weeks (ETW). METHODS: We selected patients with CD receiving maintenance therapy with ADM 40 mg ETW with serum levels (SL) available before and after dose de-escalation. Sex- and age-matched controls continuing ADM 40 mg EOW were identified. Patient reported outcome, C-reactive protein (CRP) and serum albumin were collected...

BACKGROUND: The introduction of anti-tumor necrosis factor medications has revolutionized the treatment of psoriasis with achievement of treatment goals (Psoriasis Area and Severity Index score 75, remission) that are not usually met with conventional systemics. Nevertheless, some patients continue to experience persistent disease activity or treatment failure over time. Strategies to optimize treatment outcomes include the use of concomitant methotrexate, which has demonstrated beneficial effects on pharmacokinetics and treatment efficacy in psoriasis and other inflammatory diseases...
