ATI were not detectable in serum if infliximab concentration was ≥0.3 μg/mL and were regarded as inconclusive for ATI. For the pharmaco-economic evaluation of the optimization phase, infliximab costs of the optimized treatment regimen were compared with those of the treatment regimen at baseline in year 2012 values. Infliximab ADA formation is defined as any detectable amount of ADA in the absence of detectable serum infliximab (measured by enzyme-linked immunosorbent assay, ELISA). Secondary Outcome Measures : Infliximab levels were measured by ELISA (lowest detectable level = 0.1 μg/ml). Modeling serum profiles for each of the dosing regimens were used to determine the benefit of a dose increase versus a change in dosing interval frequency to achieve adequate clinical response. Results: If infliximab level is sub-therapeutic and total infliximab anti-drug antibody is detected: Detectable serum infliximab anti-drug antibody may cause accelerated infliximab clearance leading to reduced trough levels and a compromised clinical response. 2020-10-20 · Infliximab serum concentrations remained detectable in one infant until 12 months of age (Julsgaard 2016).
2019-10-03 Development of antibodies to infliximab increased infliximab clearance. At 8 weeks after a maintenance dose of 3 to 10 mg/kg of REMICADE, median infliximab serum concentrations ranged from approximately 0.5 to 6 mcg/mL; however, infliximab concentrations were not detectable (<0.1 mcg/mL) in patients who became positive for antibodies to infliximab. called Anser IFX (for infliximab), Anser ADA (for adalimumab), Anser VDZ (for vedolizumab), and Anser UST (for ustekinumab). The tests measure both serum drug concentrations and ADA. They are not based on an ELISA test, and can measure ADA in the presence of detectable drug levels, improving on a major limitation of the ELISA method. Detectable trough serum infliximab was present in only 39% of 115 patients after a median interval from the baseline infusion of 10.7 months or within 8 weeks of cessa- Predictors of Infliximab Clearance. Increased body weight, increased ADA concentrations, decreased serum albumin concentrations, and increased CRP or serum glucose concentrations were each predictive of higher baseline infliximab clearance (Figure 1).Over the range of body weight in the database (34–139 kg), baseline clearance ranged from 0.16 to 0.43 L/day.

Detectable trough infliximab concentrations have been associated with higher remission rates and superior endoscopic healing in both CD and moderately to severely active ulcerative colitis (UC), lower concentrations of CRP in CD and lower colectomy rates in UC. 6, 7 In these observational studies, undetectable trough concentrations of infliximab, which occurred in both antibody‐positive and Radstake TRDJ et al. Formation of antibodies against infliximab and adalimumab strongly correlates with functional drug levels and clinical responses in rheumatoid arthritis. Ann Rheum Dis 2009;68:1739–1745.

We conducted a review to evaluate the utility of TDM in the assessment and subsequent management of IFX loss of response in our pediatric population with Crohn disease (CD).. Methods: Single-center retrospective study of patients with CD receiving IFX Infliximab levels were measured by ELISA (lowest detectable level = 0.1 μg/ml). Modeling serum profiles for each of the dosing regimens were used to determine the benefit of a dose increase versus a change in dosing interval frequency to achieve adequate clinical response. Results: A detectable trough serum infliximab was also associated with a lower C-reactive protein (2.0 vs 11.8 mug/L; P < .001) and a higher rate of endoscopic improvement (88% vs 33%; P < .001). Concurrent immunomodulators did not alter outcomes. If infliximab level is sub-therapeutic and total infliximab anti-drug antibody is detected: Detectable serum infliximab anti-drug antibody may cause accelerated infliximab clearance leading to reduced trough levels and a compromised clinical response.
Favorable efficacy was observed in patients with detectable serum infliximab levels (≥0.1 μg/mL) at baseline.

A case report describes serum concentrations in the newborn following maternal use of infliximab during pregnancy for psoriatic arthritis. detectable pre-infusion anti-infliximab antibodies (0/20 patients, p < 0.001).

Detectable trough serum infliximab was present in 39% of patients and, among patients with undetectable infliximab, 41% were antibody positive and 20% were antibody negative. For antibody-positive and antibody-negative patients, rates of remission (18% vs 14%), endoscopic improvement (25% vs 35%) and colectomy (52% vs 59%) were not different. rate with this cut point was 3%.

LISA-TRACKER Infliximab is an enzyme linked immunoassay (ELISA) for the quantitative determination of Infliximab (anti-TNFα) in human serum samples. Scientific Description Anti-TNFα are therapeutic agents widely used to treat patients with various inflammatory diseases. Serum concentrations of infliximab and antibodies to infliximab (ATI) and DAS28 and EULAR clinical response parameters were recorded for one year.

The presence of detectable ATI is independently associated with a shorter duration of response.² A serum infliximab concentration ≥3 ug/ml at trough is associated with a mean CRP level that is 52% less than in samples having an infliximab concentration <3 ug/ml.³ Infliximab serum levels during a single infusioncycle categorized as patients with and without detectable anti-infliximab antibodies are depicted in figure 1 and 2. At 50% of the infusioncycle 5/7 (71% ± 33%) of the patients with HACAs just before the next infusion had low infliximab serum levels (< 1 mg/l) which was significantly more frequent compared to 0/20 of the non-antibody forming patients (p < 0.001). (Anti) Infliximab concentrations. Table 2 shows the median infliximab levels and the decrease of infliximab serum trough levels during the infusioncycle.
