Viral Safety With BeneFIX
Tests on donated blood and plasma have been mandated because of the history of pathogen transmission through blood- and plasma-derived products
Some pathogens associated with blood products46,47
| Category |
Examples |
| Lipid-enveloped viruses |
Human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) |
| Non–lipid-enveloped viruses |
Hepatitis A virus (HAV), parvovirus B-19 |
| Prion |
Variant Creutzfeldt-Jakob disease (vCJD) |
Non–lipid-enveloped viruses are more resistant to viral inactivation processes (such as heating or solvent/detergent washes) than lipid-enveloped viruses2,3
- Screening tests are currently under development for detecting prion diseases such as Creutzfeldt-Jakob disease (CJD) and vCJD4
BeneFIX is produced through recombinant technology in which the product is not derived from animal or human sources
"...[BeneFIX] is inherently free of human blood-borne pathogens, including any risk of human immunodeficiency virus (HIV), hepatitis, parvovirus, and Creutzfeldt-Jakob disease (CJD)."—Adamson et al5
"...there are justified concerns about the safety of large-pool blood protein concentrates for patients such as those with hemophilia for whom continuous usage results in exposure to millions of blood donors during one's life."—Roth et al6
- As many as 60,000 separate donations contribute to a single lot of plasma-derived product7
- The larger the size of the plasma pool for fractionated plasma-derived products, the greater the probability that blood-borne pathogens will be included7
- MASAC recommends that plasma pools be decreased in size to levels approaching 15,000 donations per lot of finished product2
BeneFIX is produced without human donors or animal proteins; it is therefore inherently free from the risk of transmission of human blood-borne pathogens
Indication BeneFIX is indicated for the control and prevention of hemorrhagic episodes
in patients with hemophilia B (congenital factor IX deficiency or Christmas disease), including control and prevention
of bleeding in surgical settings. BeneFIX is not indicated for the treatment of other factor deficiencies (eg, factors II, VII, VIII and X)
nor the treatment of hemophilia A patients with inhibitors to factor VIII, nor the reversal of coumarin-induced anticoagulation, nor the
treatment of bleeding due to low levels of liver-dependent coagulation factors.
Important Safety Information
 |
|
As with the intravenous administration of any protein product, common adverse reactions may include headache, fever, chills, flushing, nausea, vomiting, or tiredness. |
 |
|
BeneFIX may be contraindicated in patients with a known history of hypersensitivity to hamster protein. |
 |
|
Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported for all factor IX products. Patients should be informed of the early symptoms and signs of hypersensitivity reactions. Patients should discontinue use of the product and contact their health care provider immediately and/or seek emergency care if any hypersensitivity reactions occur. |
