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).

PROMETHEUS SERUM INFLIXIMAB/HACA MEASUREMENT Test ID: FPHAC Secondary ID: 91563 EXPLANATION OF CHANGE: Notification has been received from Prometheus Laboratories, Inc., effective August 17, 2012, Test ID FPHAC, will no longer be offered. ALTERNATIVE TEST: Alternative testing will not be available through MML. Clients will need 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. Incorporating drug Antibody assay and Prometheus’ Anser IFX test ARUP’s Infliximab Activity and Neutralizing Antibody assay (test code 2008320) is a cell-based bioassay that measures the ability of infliximab to inhibit TNF-alpha. The assay also detects the presence of antibodies that neutralize infliximab activity.

PROMETHEUS® Anser® UST - #3190 Simultaneously measures ustekinumab (UST) and antibodies to ustekinumab (ATU) levels in serum.

Policy reviewed and revised 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). 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 … - Data provide further evidence for standardized, combined, antibody-to-infliximab and serum infliximab level monitoring among IBD patients on infliximab - - Oral presentation one of 13 Prometheus abstracts at Digestive Disease Week 2012 - San Diego, May 22, 2012 – Prometheus Laboratories Inc., a specialty pharmaceutical and diagnostic Serum infliximab (IFX) concentration < 1.0 ug/mL. 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. Infliximab binds to soluble TNF-a and transmembrane homotrimers, which are found on the surface of macrophages and T-cells, with similar affinity. 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. 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.

This test was preformed 4 weeks into a 8 week cycle. As a result of this high level, and confirmed remission, his doctor suggests extending cycle from 8 weeks to 10 weeks. He is on the lowest All serum samples were analyzed for CRP, albumin, TNF, IFN-γ, IL-6, IL-8, IL-10, infliximab trough concentrations (in-house-developed ELISA) and antibodies to infliximab (HMSA, Prometheus Laboratories Inc., San Diego, CA). Primary non-response was defined as the absence of clinical improvement at week 14. with adalimumab (ADA), infliximab (IFX/IFX biosimilars), ustekinumab (UST), and vedolizumab (VDZ).
