Serum concentrations of IFX may vary among equally dosed patients which can develop immunogenicity to IFX by producing antibodies to Infliximab (ATI).

Results of recent studies suggest that serum IFX concentration predicts long-term clinical response [ 5 ]. PROMETHEUS® Anser® IFX measures both serum infliximab levels and antibodies to infliximab – valuable information to help guide your treatment decisions for patients who lose response to infliximab. 2020-07-15 · Abstract. Despite a robust exposure–response relationship of infliximab in inflammatory bowel disease (IBD), attempts to adjust dosing to individually predicted serum concentrations of infliximab (SICs) are lacking.

Mean serum infliximab levels were 5.46 +/- 5.62 microg/ml 2 weeks after the final administration of infliximab, 2.02 +/- 1.66 microg/ml just before the operation, and 1.48 +/- 1.31 microg/ml 1 day post operation. The trough concentration (TC) of infliximab, which is the drug concentration in serum just before the next infusion, has been linked to biological, clinical, and endoscopic outcomes. 1, 2, 3 Recently, several prospective trials have identified concentration-based dosing as a cost-effective alternative to clinically based dosing. 4, 5 However, dosing could only be adapted at the next infusion At week 14 of treatment, patients were randomly assigned (1:1:1) to 3 infliximab maintenance groups: dose increases (2 maximum) in steps of 2.5 mg/kg based on clinical symptoms and biomarker analysis and/or serum infliximab concentrations (dose intensification strategy [DIS]1 group); dose increase from 5 to 10 mg/kg based on the same criteria (DIS2 group); dose increase to 10 mg/kg based on clinical symptoms alone (controls). Patients' CD activity index scores, levels of C-reactive protein, fecal levels of calprotectin, and serum concentrations of infliximab were determined at baseline and at weeks 2, 4, 6, 12, and 14 Provides infliximab drug concentration levels as well as levels of anti-infliximab antibodies. In the absence of anti-infliximab antibodies, the infliximab drug level typically reflects the total infliximab concentration in serum. Objective Although low infliximab trough concentrations and antibodies to infliximab (ATI) are associated with poor outcomes in patients with Crohn's disease (CD), the clinical relevance of ATI in patients with adequate infliximab concentrations is uncertain.

The serum concentration of infliximab obtained 1 hour after infusion approximates the C max for infliximab. At week 0, the median serum concentrations of the 1 hour–postinfusion samples were 68.6 μg/ml and 219.1 μg/ml for subjects receiving 3 mg/kg and 10 mg/kg infliximab, respectively, every 8 weeks (Table 1 ).

We sought to compare 2 point-of-care (POC) devices for quantification of serum infliximab concentration with 2 validated ELISA assays in children with IBD.

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.

Low trough concentrations may be correlated with loss of response to infliximab.
