coagulation factor ix recombinant - Generic Medications

IXINITY [coagulation factor IX (recombinant)] is a purified protein that has 415 amino acids. It has an amino acid sequence that is comparable to the Thr148 allelic form of plasma-derived factor IX. Coagulation factor IX (recombinant) is a single-chain glycoprotein with a molecular mass of about 55,000 Dalton that is secreted by a genetically engineered mammalian cell line derived from Chinese hamster ovary (CHO) cells. No human or animal proteins are added during any stage of manufacturing or formulation of IXINITY. The CHO cell line secretes recombinant factor IX into a defined cell culture medium that does not contain hormones. The recombinant factor IX is purified by a chromatography purification process. The process includes three validated steps for virus inactivation and removal, namely, solvent/detergent treatment, a chromatographic step, and nanofiltration. The process also includes a validated step to reduce the presence of CHO proteins in the final drug product. IXINITY is formulated as a sterile, nonpyrogenic lyophilized powder to be reconstituted with Sterile Water for Injection for intravenous administration. It does not contain any preservatives and is available in single-dose vials containing the labeled amount of factor IX activity, expressed in international units (IU). Each vial contains nominally 250, 500, 1000, 1500, 2000, or 3000 IU of recombinant coagulation factor IX. After reconstitution of the lyophilized powder, all dosage strengths yield a clear, colorless solution. The concentrations of excipients are: Excipient Concentration Histidine 10 mM Mannitol 3% Trehalose Dihydrate 1% Sodium Chloride 66 mM Polysorbate 80 0.0075%
