Description

Octagam 10% is an immune globulin intravenous (human) liquid preparation indicated for the treatment of. Chronic immune thrombocytopenic purpura (ITP) in adults ( 1.1 ). Dermatomyositis (DM) in adults ( 1.2 ).

Immune Globulin Intravenous (Human), Octagam 10%, is a solvent/detergent (S/D)-treated, sterile preparation of highly purified immunoglobulin G (IgG) derived from large pools of human plasma. Octagam 10% is a solution for infusion to be administered intravenously. This preparation contains approximately 100 mg of protein per mL (10%) of which not less than 96% is normal human immunoglobulin G. Octagam 10% contains not more than 3% aggregates, not less than 94% monomers and dimers and not more than 3% fragments. On average, the product contains 106 µg/mL of IgA and even lower amounts of IgM. The sodium content of the final solution is not more than 30 mmol/L and the pH is between 4.5 and 5.0. The osmolality is 310 - 380 mosmol/kg. The manufacturing process for Octagam 10% isolates IgG without additional chemical or enzymatic modification, and the Fc portion is maintained intact Octagam 10% contains the IgG antibody activities present in the donor population. IgG subclasses are fully represented with the following approximate percents of total IgG: IgG 1 is 65%, IgG 2 is 30%, IgG 3 is 3% and IgG 4 is 2%. Octagam 10% contains a broad spectrum of IgG antibodies against bacterial and viral agents that are capable of opsonization and neutralization of microbes and toxins. It contains maltose (90 mg/mL), but no preservatives or sucrose. All units of human plasma used in the manufacture of Octagam 10% are provided by FDA-approved blood establishments, and are tested by FDA-licensed serological tests for HBsAg, antibodies to HCV and HIV and Nucleic Acid Test (NAT) for HCV and HIV-1 and found to be non-reactive (negative). The product is manufactured by the cold ethanol fractionation process followed by ultrafiltration and chromatography. The manufacturing process includes treatment with an organic S/D mixture composed of tri-n-butyl phosphate (TNBP) and Triton X-100 (Octoxynol). The Octagam 10% manufacturing process shows significant viral reduction in in vitro studies (Table 6). These reductions are achieved through a combination of process steps including cold ethanol fractionation, S/D treatment and pH 4 treatment.
