Manufacturing and Pathogen Safety
Octapharma has pioneered a number of safety innovations that have set the standard for the protein products industry
Octagam 5% manufacturing and purification process1-3
octagam 5% contains all 4 subclasses of IgG, with a percentage distribution equivalent to the one found in normal plasma
- Octagam 5% is made from large pools of donated plasma which go through a rigorous purification process for the inactivation and removal of viruses
- Other precautions against viral transmission include: selection of plasma donors, screening of donations and plasma pool, as well as final product testing for viruses
- Octagam 5% is manufactured by cold ethanol fractionation followed by ultrafiltration and chromatography. The manufacturing process includes treatment with a solvent/detergent, and incubation at low pH
Validated viral removal and inactivation process
The manufacturing process for octagam 5% has been validated for its capacity to remove and inactivate both enveloped and non-enveloped viruses1
All units of human plasma used in the manufacture of octagam 5% liquid are collected in US-based Octapharma Plasma centers that are licensed by the US Food and Drug Administration (FDA). Plasma is 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).
