Viral Safety
NovoSeven® RT—The Only Recombinant Bypassing Agent
NovoSeven® RT contains no human plasma-derived components, so there is no risk of human viral transmission. Although plasma-derived products undergo a stringent cleaning process, they are able to ensure protection against only known viruses. Because it is recombinant, NovoSeven® RT ensures safety from pathogens that can be transmitted through human blood.
The Medical and Scientific Advisory Council (MASAC) of the NHF, in their Recommendation #169, recommends recombinant products as the standard of care for various bleeding disorders. According to MASAC #169:
''[T]he recombinant Factor VIIa product NovoSeven is potentially the safest Factor VII product available with respect to pathogen transmission and should be considered the treatment of choice for individuals with congenital Factor VII deficiency. In all patients, including patients with inhibitors, the issue of pathogen transmission must be weighed against the issue of efficacy."72
Emerging Pathogens
There are more than 1,400 known pathogens that can infect and sicken humans69 and new pathogens are being discovered—38 new pathogens since 1980.69 Emerging pathogens create constant and serious concern, especially for people with bleeding disorders, as there is no way to screen blood or plasma for unknown pathogens.
Examples of pathogens that have emerged or reemerged in the past decades include:
- West Nile virus
- Severe Acute Respiratory Syndrome (SARS)
- Monkeypox virus
- Ebola virus
- Avian flu
- Nipah virus
- Variant Creutzfeldt-Jakob disease (vCJD) prions
Physiological and environmental forces invite the rapid growth and spread of new pathogens.
- Cells are constantly mutating
- Population growth into uninhabited areas introduces new pathogens and alters biological systems
- Modern travel circulates pathogens rapidly
As a recombinant therapy made without any human blood or plasma, NovoSeven® RT poses no risk of passing human viruses.
Previously Infected Patients
Approximately 18,000 people have hemophilia in the United States.94 Of those, an estimated 10% to 15% are infected with HIV as a result of contaminated blood or blood products.71
The goal is to keep people with a suppressed immune system who are
already living with one infection from getting
another infection, called co-infection. Co-infection
further weakens the immune system, leaving people susceptible to pathogens
that are harmless to those with healthy immune systems. Additionally,
medications used to treat HIV and hepatitis are known to suppress
the immune system which can further complicate care.
