Idarucizumab is a humanized monoclonal antibody fragment (Fab) derived from an IgG1 isotype molecule, whose target is the direct thrombin inhibitor dabigatran. Using recombinant expression technology, idarucizumab is produced in a well characterized recombinant (mammalian) CHO cell line and is purified using standard technology. Idarucizumab is composed of a light chain of 219 amino acids and a heavy chain fragment of 225 amino acids, covalently linked together by one disulfide bond between cysteine 225 of the heavy chain fragment and cysteine 219 of the light chain, and has an estimated molecular mass of approximately 47,766 Daltons. PRAXBIND (idarucizumab) is a sterile, preservative-free, colorless to slightly yellow, clear to slightly opalescent solution for intravenous administration. PRAXBIND (idarucizumab) is supplied in 2 single-dose vials, each containing 2.5 g of idarucizumab in 50 mL formulated as a buffered, isotonic, solution containing acetic acid glacial (10.05 mg), polysorbate 20 (10 mg), sodium acetate (88.82 mg), sorbitol (2004.20 mg), and water for injection with an osmolality of 270-330 mOsm/kg and a pH of 5.3-5.7.
