08/25/17: Changed name from Measurement of Serum Antibodies to Infliximab and Adalimumab to Measurement of Serum Antibodies to Infliximab, Adalimumab, & Vedolizumab. Added testing for the measurement of antibodies to vedolizumab (e.g., Prometheus® Anser™ VDZ) as non-covered for all product lines. Policy reviewed and revised 2021-01-19 · Serum, one 5.0 mL gold (SST) or 7.0 mL red top tube Handling Allow serum to clot completely at room temperature (minimum: 30 minutes). 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.

Papamichael K, Vajravelu RK, Vaughn BP, Osterman MT, Cheifetz AS. 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). Validation was demonstrated using specimens from Inflectra-treated patients with IBD. The PROMETHEUS ® Anser ® IFX test is a new generation and more sensitive quantitative infliximab monitoring assay that allows healthcare providers to measure and monitor serum IFX and ATI levels at anytime during therapy. Incorporating drug monitoring may clarify what factors are contributing to a The drug-tolerant PROMETHEUS®Anser®Test with proprietary homogeneous mobility shift assay (HMSA) technology: Provides objective measurements and actionable results to help ensure that: Patients have therapeutic levels of adalimumab (ADA), infliximab (IFX, including biosimilars), ustekinumab (UST), or vedolizumab (VDZ) that have been associated with 2021-01-19 The Prometheus Anser ® tests are quantitative monitoring assays that allow healthcare providers to measure and monitor both the levels of drug and anti-drug antibodies at anytime during therapy. 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.

Hernandez-Breijo B, Chaparro M, Cano-Martinez D, et al. Standardization of the homogeneous mobility shift assay protocol for evaluation of anti-infliximab antibodies. We have developed a non-radio labeled homogeneous mobility shift assay to measure the antibodies-to-infliximab (ATI) and drug levels in serum from patients treated with infliximab (IFX).

The HACA portion of the test detects human anti-chimeric antibodies (HACA / antibodies to infliximab). Patients that develop HACA may experience infusion reactions and/or a reduced duration of efficacy of infliximab.
