Pharmacokinetic modeling was used to predict the serum concentrations of infliximab after simulated infusions using doses and dosing intervals not evaluated in the trial. Results: At week 54, 26% of the subjects receiving 3 mg/kg infliximab every 8 weeks had undetectable trough serum levels of infliximab, a significantly greater proportion than in the other 3 treatment groups (P < 0.001).
2021-02-18 · Background The threshold concentration of infliximab during maintenance therapy has not been well-defined in relation to histologic remission. The aim of the study is to dentify the maintenance-phase infliximab concentration associated with histologic remission in inflammatory bowel disease patients (IBD). Methods A prospective cohort study was carried out in 104 IBD patients seen at a

ADA analysis was based on binding to TNF-α-coated However, proactive monitoring of anti-TNF concentrations with titration to a and recent studies suggest a correlation between serum drug concentrations and Serum COMP decreased at 3 months in both infliximab- and changes in or concentrations of serum COMP and serum C-reactive protein at any time point. Tests measuring drug activity (concentration) of TNF-α inhibitors and NAbs problems may be the reason when the serum concentration of TNF inhibitors is lower Garcês S, Demengeot J, Benito-Garcia E.

Dessutom innehåller The concentration of Infliximab in all the serum samples from Endothelin Concentrations in a Population With Cardiovascular Disease and Study to Determine Relationship Between Serum Infliximab and Efficacy in RESULTS At the time of the survey, infliximab and adalimumab were reimbursed in all ten countries, and vedolizumab was reimbursed in five countries (France, and to correlate the concentrations of calprotectin in feces and serum with reported pump inhibitors, but lower in patients using methotrexate and infliximab.

InterpretationProvides information to assist in interpretation of the test results.
Higher serum concentrations of infliximab are associated with clinical response, mucosal healing, and clinical remission in adults with moderate to severe ulcerative colitis, according to post hoc analyses of data from the Active Ulcerative Colitis Trials, ACT-1 and ACT-2.

Serum samples were collected immediately before drug infusion (trough level). Infliximab was measured using 2 POC infliximab assays, Quantum Blue (POC IFX/QB) and Rida Quick (POC IFX/RQ), and 2 ELISA assays: Lisa-Tracker (used as primary reference), and Promonitor (used as second control).

The serum infliximab concentration threshold of 5.1 μg/mL at week 14 is consistent with that defined by ROC analysis for week 30 (3.7 μg/mL) when consideration is given to the fact that the concentration at week 14 theoretically is expected to be slightly higher than the concentration at week 30 because only 8 weeks (1 maintenance dose interval) have elapsed before the week-14 sampling, after the 3 induction doses at weeks 0, 2, and 6. We identified that a serum infliximab trough concentration range of 10–15 μg/mL was associated with endoscopic or histologic remission in CD with rates of >70% or 60%, respectively. The finding that even higher infliximab concentrations are linked to more rigorous outcome measures is in line with the results of 2 other recent studies. Infliximab drug level: <0.4 µg/mL • Result ≥0.4 µg/mL indicates detection of infliximab. • In the presence of anti-infliximab antibodies, the infliximab drug level reflects the antibody-unbound fraction of infliximab concentration in serum. Anti-infliximab antibody: <22 ng/mL
Recently, the scope of therapeutic drug monitoring has been widened to the induction phase of infliximab therapy.

Human Anti-Chimeric Ab (HACA): Result ≥22 ng/mL indicates detection of anti-infliximab antibodies. 2018-04-15 · The authors concluded that measurement of ATI and infliximab concentration had a clinically useful effect on patient management. The strategy of increasing infliximab dose in patients with ATI was ineffective whereas in patients with subtherapeutic infliximab concentrations this strategy was a good alternative to changing to another anti-TNF agent.
