描述
PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human TFPI antigen has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Concizumab in the sample competitively binds to the pre-coated protein with biotin-labeled Concizumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Concizumab bound in the initial step. The color development is stopped and the intensity of the color is measured.

背景
Concizumab (mAb 2021) is a high-affinity, humanized, monoclonal IgG4 antibody (mAb) developed by Novo Nordisk A/S. It was directed against the Kunitz-2 domain of human tissue factor (TF) pathway inhibitor (TFPI), designed to target and selectively block the factor X (FX) a (FXa) binding site of TFPI. As a mAb, concizumab has the advantage of being administered subcutaneously, and exhibits good solubility and stability, allowing administration as a liquid formulation via a ready- and easy-to-use portable pen device. Phase 2 trials of concizumab are ongoing for Haemophilia A and B. On 12 October 2017, orphan designation (EU/3/17/1940) was granted by the European Commission to Novo Nordisk A/S, Denmark, for concizumab for the treatment of haemophilia B.
