Therapeutic Safety
Safety Advantages with NovoSeven® RT
No Risk of Increased Titers
Low titers are clinically important in the treatment of
bleeding episodes,92 for
immune tolerance induction (ITI), 73,59 and
in surgery.93
- NovoSeven® RT is recombinant FVIIa and has no potential for anamnestic reaction
- Treatment with recombinant FVIIa does not increase inhibitor titers .73
Titer levels after use with Recombinant Factor VIIa
Adapted from Brackman et al.73
Data from a study of patients with hemophilia A and high-responding inhibitors. Ten were given recombinant FVIIa for treatment of bleeds; 6 of these patients were also undergoing ITI. Figure lines reflect decreases in inhibitor titers after switch to recombinant Factor VIIa in the 4 patients not undergoing ITI.73
Low Risk of Thrombotic Events
- Demonstrated through extensive use (>400,000 standard doses [90mcg/kg administered)91

a Thrombotic events since approval of recombinant Factor VIIa in 1996 (up to the end of 2002) in patients with inhibitors (acquired or congenital).
Low Incidence of Adverse Events
Even after extensive use (>400,000 standard doses [90 mcg/kg] administered), rate of serious adverse events with recombinant Factor VIIa was low91
The most common adverse events in people taking NovoSeven® RT are:85
- Pyrexia
- Hemorrhage
- Injection site reaction
- Arthralgia
- Headache
- Hypertension
- Hypotension
- Nausea
- Vomiting
- Pain
- Edema
- Rash
Low Risk of Drug Interactions
There have been no reported drug interactions with nonhemostatic agents, including analgesics, antibiotics, and sedatives.66
