Promonitor®-anti-ETN Ref. 512XX30000

Quantitative measure of anti-etanercept antibodies. Promonitor®-anti-ETN is an enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of anti-etanercept antibodies in human serum samples. The amount of Anti-Drug Antibodies (ADA), when considered in conjunction with drug levels (Promonitor®-ETN Ref. 5110230000) and clinical findings, like disease activity, can contribute valuable information to the physician to assess the efficacy of therapies with etanercept (ETN). It is known that any biological drug can be potentially immunogenic and induce the formation of ADA, thereby potentially reducing treatment efficacy. In the case of other anti-TNF treatments like infliximab and adalimumab, it has been extensively demonstrated that low drug levels and ADA formation strongly correlate with a loss of clinical response in several pathologies like rheumatoid arthritis, spondyloarthritis, Crohn´s disease and psoriasis. It has also been described that patients not responding to etanercept obtain lower etanercept concentrations compared with responding patients. Promonitor®-anti-ETN is a bridging ELISA to test up to 40 patients. The microwell strips are provided pre-coated with ETN. The bridging ELISA takes advantage of the two arms of IgG subclasses 1, 2 and 3, to crosslink the ETN coated on the plate. Calibrators, controls and diluted patient samples are added to separate wells, allowing anti-ETN antibodies present to bind to pre-immobilized ETN. Unbound sample is washed away, and HRP-labeled ETN is added to each well. A second incubation step allows the HRP-labeled ETN to bind to the antibodies that have become attached to the microwells. After washing away the excess of unbound HRP conjugate, the remaining enzyme activity is measured by adding a chromogenic substrate and measuring the intensity of the color that develops in a spectrophotometer. The signal obtained is proportional to the amount of anti-ETN antibodies in the patient sample. Warnings for each sample are optionally included; this setting can be configured here.

Promonitor®-ETN Ref. 511XX30000

Quantitative measure of etanercept. Promonitor®-ETN is an enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of free etanercept (ETN) in human serum samples. The amount of ETN, when considered in conjunction with anti-ETN antibodies (Promonitor®-anti-ETN Ref. 5120230000) and clinical findings, like disease activity, can contribute valuable information to the physician to assess the efficacy of therapies with ETN. It has been described that patients not responding to etanercept obtain lower etanercept concentrations compared with responding patients. Promonitor®-ETN is a sandwich ELISA to test up to 40 patients. The microwell strips are provided pre-coated with an anti-ETN human F(ab´)2 fragment. Diluted calibrators, controls and diluted patient samples are added to separate wells, allowing ETN present to bind to pre-immobilized anti-ETN antibodies. Unbound sample is washed away, and a second HRP-labeled anti-ETN monoclonal antibody is added to each well. A second incubation step allows the HRP-labeled anti-ETN antibody to bind to the ETN that has become attached to the microwells. After washing away the excess of unbound HRP-labeled anti-ETN antibody, the remaining enzyme activity is measured by adding a chromogenic substrate and measuring the intensity of the color that develops in a spectrophotometer. The signal obtained is proportional to the amount of drug in the patient sample. Optical densities (OD) of the calibrators are plotted to construct the ETN calibration curve. A four parameter logistic (4PL) model is used to fit the curve. Positive and Negative Controls are used to monitor assay performance. ETN concentration is calculated by interpolating sample OD in the calibration curve. Warnings for each sample are optionally included; this setting can be configured here.

Promonitor®-anti-IFX Ref. 507XX30000

Quantitative measure of anti-infliximab antibodies. Promonitor®-anti-IFX is an enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of anti-infliximab antibodies in human serum samples. The amount of anti-infliximab antibodies, when considered in conjunction with the infliximab (IFX, Remicade®) level (Promonitor®-IFX Ref. 5060230000) and clinical findings, like disease activity, contributes valuable information to the physician to assess the efficacy of therapies with IFX, predict infusion-related reactions and loss of clinical response by the patient. Due to its chimeric structure, IFX often raises an unwanted immune response in the treated patient, causing Anti-Drug Antibodies (ADA) to form. All Anti-IFX antibodies are neutralizing anti-idiotypic antibodies which can render the therapy completely useless. It is also known that the presence of high titers of anti-IFX antibodies may be related to severe complications like infusion-related reactions.
