Importantly, they have been validated with more than 4,000 clinical IBD patient samples and are supported by multiple peer-reviewed publications. 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 anytime during therapy. Simultaneously measures infliximab (IFX) and antibodies to infliximab (ATI) levels in serum at any time during therapy. Can also be used with IFX biosimilars.

This test is set to be discontinued in August 2012 and replaced with an HMSA called the Anser™IFX test. The Anser IFX test is not ELISA-based and can measure antibodies to infliximab in the presence of serum infliximab, improving upon a major limitation of the ELISA method. 301 Moved Permanently.
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.

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). Dosing was blinded to PK data. 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.

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.
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.

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. Infliximab Level and Anti-drug Antibody for IBD - When treatment of inflammatory bowel disease with infliximab or its biosimilar fails, a physician may need to consider treatment options, such as adjusting dose or dosing intervals, switching to a different TNF blocker, or switching to a non-TNF blocker. 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.
