A detectable serum infliximab was associated with higher rates of remission (69% vs 15%; p<0.001) and endoscopic improvement (76% vs 28%, p<0.001). An undetectable serum infliximab predicted an increased risk for colectomy (55% vs 7%, OR 9.3; 95% CI 2.9 to 29.9; p<0.001). Concurrent immunosuppression was not associated with clinical outcomes.

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.

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).

Background: Anti-infliximab antibodies (ATIs) are associated with lower serum infliximab (IFX) trough levels and diminished clinical response. The current most prevalent method for detection of ATI is a double-antigen (DA) enzyme-linked immunosorbent assay (ELISA) utilizing IFX for ligand and detection antibody.
An undetectable serum infliximab predicted an increased risk for colectomy (55% vs 7%, OR 9.3; 95% CI 2.9 to 29.9; p<0.001). A detectable serum infliximab was associated with higher rates of remission (69% vs 15%; p<0.001) and endoscopic improvement (76% vs 28%, p<0.001). An undetectable serum infliximab predicted an increased risk for colectomy (55% vs 7%, OR 9.3; 95% CI 2.9 to 29.9; p<0.001). Concurrent immunosuppression was not associated with clinical outcomes. 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).
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. with infliximab, a detectable trough serum infliximab predicts clinical remission, endoscopic improvement and a lower risk for colectomy.
