Though the assay for an infliximab level is commercially available, current dosing practices rely on the assessment of clinical data (laboratory data, symptoms, colonoscopy, etc). In order to understand this relationship, serum infliximab and ATI titers will be collected over the course of 8 (approximately 1 year) infusions. Measurement of Serum Antibodies to Infliximab and Adalimumab Policy Number: 2.04.84 Last Review: 12/2013 Origination: 2/1/2013 Next Review: 12/2014 Policy Blue Cross and Blue Shield of Kansas City (Blue KC) will not provide coverage for measurement of serum antibodies to Infliximab. This is considered investigational. 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 Samples were analysed first by ELISA (Prometheus) and later with a homogenous mobility shift assay (HMSA; Prometheus). In the proactive monitoring group, serum trough levels of infliximab guided dose change to achieve target drug levels according to the algorithm presented in table 3. Anti-TNF Monitoring Test PROMETHEUS® Anser® IFX Demonstrates Equivalence for Measuring Inflectra Serum Drug and Antidrug Antibody Levels San Diego, CA April 7, 2016 – Prometheus Laboratories Inc. announced today that the PROMETHEUS Anser IFX test has been validated for use in patients treated with Inflectra (biosimilar infliximab) in the management of inflammatory bowel disease (IBD).

Antibodies to infliximab (ATI) Concentration < 1.6 U/mL This test was developed and its performance characteristics determined by Prometheus Laboratories Inc. It has not been cleared or approved by the U.S. Food and Drug Administration. INFXR : Infliximab (Remicade, Renflexis, Inflectra) is a chimeric immunoglobulin (IgG1 kappa) targeting tumor necrosis factor-alpha (TNF-a), and it is currently FDA-approved for the treatment of multiple inflammatory conditions.
Each serum sample was assessed for infliximab and antibodies against infliximab in duplicate in a blinded fashion by Prometheus Laboratories; the values reported are the means. Fifty IBD patients completing IFX induction were monitored during maintenance (weeks 14-54). Clinical and laboratory data were collected at each infusion; serum was analyzed for IFX concentrations and anti-drug antibodies (ADA) at weeks 14 and 54 (Prometheus Labs, San Diego).

Incorporating drug monitoring may clarify what factors are contributing to a patient’s loss of response and help guide treatment decisions by providing information to help determine an appropriate PROMETHEUS Anser™ IFX designed to help identify potential causes for loss of treatment response among IBD patients using infliximab San Diego, May 22, 2012 – Prometheus Laboratories Inc., a specialty pharmaceutical and diagnostic company, announced today the thirteen abstracts relating to its proprietary diagnostic platform presented at Digestive Disease Week (DDW) 2012. 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 Measuring both serum infliximab level and ATI concentration can provide clinically useful information to aid in the management of patients on infliximab therapy.⁴ a PROMETHEUS@ Thiopurine Metabolites - #3200 Thiopurine metabolite (6-TGN, 6-MMPN) levels Optimize ongoing dosing of thiopurines to reach and maintain therapeutic goal Current therapeutic: D 6-MP mg/day C] AZA mg/day a Other mg/day C] PROMETHEUSS FIBROSpece Il - #4000 PROMETHEUS@ Serum Infliximab/HACA Measurement - #3130 In the presence of anti-infliximab antibodies, the infliximab drug level typically reflects the antibody-unbound fraction of infliximab concentration in serum. The presence of infliximab drug, even at concentrations well above target treatment levels (>50 μg/mL), does not interfere with the anti-infliximab antibody detection.
