Therapeutic drug monitoring

Therapeutic drug monitoring (TDM) measures specific drugs in a patient’s bloodstream over time. This is important for developing long-term individualised care plans, which are critical for  patients with chronic inflammatory diseases. The overall aim is for the patient to reach and maintain clinical remission, but the natural course of diseases often presents a number of challenges, and so an adequate response to treatment may not be achieved by all patients. BIOHIT provides a range of TDM assays to determine patient response to various treatments. These tests help to predict the outcome of a given treatment for a given disease, which has the potential to deliver significant clinical and economic benefits.  To learn more, read our ‘Guide to the Benefits of Therapeutic Drug Monitoring‘.

Certolizumab Drug Level ELISA (IDKmonitor®)

Determination of free therapeutic certolizumab

Certolizumab is the Fab’ fragment of a recombinant humanised antibody conjugated to polyethylene glycol (PEG) and is therefore also known as “certolizumab pegol”. The IDKmonitor Certolizumab Drug Level ELISA kit is a microplate-based quantitative enzyme linked immunosorbent assay (ELISA) for the determination of free certolizumab therapeutic drug in serum and EDTA plasma samples.

Ustekinumab Free Anti-drug Antibody ELISA (IDKmonitor®)

Ustekinumab is a fully humanised IgG1 therapeutic monoclonal antibody used for the treatment of Crohn’s disease, ulcerative colitis, plaque psoriasis and psoriatic arthritis. This assay enables the reliable determination of free, unbound anti-drug antibodies.

Ustekinumab Total Anti-drug Antibody ELISA (IDKmonitor®)

Ustekinumab is a fully humanised IgG1 therapeutic monoclonal antibody used for the treatment of Crohn’s disease, ulcerative colitis, plaque psoriasis and psoriatic arthritis. This drug-tolerant assay enables the reliable determination of anti-drug antibodies even in the presence of ustekinumab.

Vedolizumab Free Anti-drug Antibody ELISA (IDKmonitor®)

The IDKmonitor Vedolizumab Free Anti-drug ELISA kit is a microplate-based quantitative sandwich ELISA for the determination of free anti-vedolizumab antibodies in plasma or serum samples. Detecting high levels of free anti-vedolizumab antibodies in patients when the drug level is low (undetectable or sub-therapeutic) may indicate poorer long-term outcomes and suggest the need to switch treatment.

Rituximab Drug Level ELISA (IDKmonitor®)

The IDKmonitor Rituximab Drug Level ELISA kit is a microplate-based quantitative assay for the determination of free rituximab from plasma or serum samples. Rituximab is a chimeric therapeutic monoclonal antibody (mAb) that targets B-cells (CD-20) in the treatment of rheumatoid arthritis, non-Hodgkin’s B-cell lymphomas, lymphocytic leukaemia, active granulomatosis with polyangiitis and microscopic polyangiitis.

Vedolizumab Drug Level ELISA (IDKmonitor®)

Vedolizumab is a recombinant protein used to treat Crohn’s disease and ulcerative colitis. The IDKmonitor Vedolizumab Drug Level ELISA kit is a microplate-based quantitative enzyme linked immunosorbent assay (ELISA) for the determination of free vedolizumab in plasma or serum samples.

Ustekinumab Drug Level ELISA (IDKmonitor®)

Ustekinumab is a recombinant protein used to treat inflammatory bowel disease (IBD). The IDKmonitor Ustekinumab Drug Level ELISA kit is a microplate-based quantitative enzyme linked immunosorbent assay (ELISA) for the determination of free ustekinumab in plasma or serum samples.

Infliximab Total Anti-drug Antibody ELISA (IDKmonitor®)

Infliximab is a recombinant protein used to treat inflammatory bowel disease (IBD). This protein can induce humoral immune responses and lead to anti-drug antibody formation, which is a major cause of loss of drug response. The IDKmonitor Infliximab Total Anti-drug ELISA kit is a ‘drug tolerant’ assay that enables the detection of anti-drug antibodies in the presence of circulating drug.

Infliximab Drug Level ELISA (IDKmonitor®)

Infliximab is a recombinant protein used to treat inflammatory bowel disease (IBD). The IDKmonitor Infliximab Drug Level ELISA kit is a microplate-based quantitative enzyme linked immunosorbent assay (ELISA) for the determination of free infliximab in plasma or serum samples.

Golimumab Drug Level ELISA (IDKmonitor®)

Golimumab is a recombinant protein used to treat inflammatory bowel disease (IBD). The IDKmonitor Golimumab Drug Level ELISA kit is a microplate-based quantitative enzyme linked immunosorbent assay (ELISA) for the determination of free golimumab in plasma or serum samples.

Etanercept Free Anti-drug Antibody ELISA (IDKmonitor®)

IDKmonitor Etanercept Free Anti-drug Antibody ELISA is a quantitative assay that detects human antibodies against etanercept in EDTA plasma and serum samples. Etanercept is a human therapeutic monoclonal antibody used to monitor treatment for chronic rheumatic diseases such as rheumatoid arthritis.

Etanercept Drug Level ELISA (IDKmonitor®)

The innovative IDKmonitor Etanercept Drug Level ELISA is a microplate-based assay that allows quantitative determination of free etanercept from plasma or serum samples. Etanercept is a human therapeutic monoclonal antibody (mAb) used to monitor treatment for chronic rheumatic diseases such as rheumatoid arthritis.

Adalimumab Total Anti-drug Antibody ELISA (IDKmonitor®)

Adalimumab is a recombinant protein used to treat inflammatory bowel disease (IBD). This protein can induce humoral immune responses and lead to anti-drug antibody formation, which is a major cause of loss of drug response. The IDKmonitor Adalimumab Total Anti-drug ELISA kit is a ‘drug tolerant’ assay that enables the detection of anti-drug antibodies in the presence of circulating drug.

Adalimumab Drug Level ELISA (IDKmonitor®)

Adalimumab is a recombinant protein used to treat inflammatory bowel disease (IBD). The IDKmonitor Adalimumab Drug Level ELISA kit is a microplate-based quantitative sandwich ELISA for the determination of free therapeutic TNFα antibodies (adalimumab) from plasma or serum samples.

Infliximab Free Anti-drug Antibody ELISA (IDKmonitor®)

Infliximab is a recombinant protein used to treat inflammatory bowel disease (IBD). This protein can induce humoral immune responses and lead to anti-drug antibody formation which is a major cause of loss of drug response.

Golimumab Free Anti-drug Antibody ELISA (IDKmonitor®)
