Data from a randomized, double-blind, parallel-group, multicenter study of patients with hemophilia A or B with and without an inhibitor. Patients were given recombinant Factor VIIa at dosing intervals of 2 to 3 hours. Percentages reflect the number of patients reporting excellent, effective or partially effective results. Response was rated as “excellent” if patient demonstrated definitive relief of pain/tenderness and/or if there was a measurable decrease in the size of the bleed (or arrest of bleeding) in 8 hours or less. An “effective” response was measured by any of these 3 events occurring from 8 to 14 hours; a “partially effective” response ether occurred after 14 hours or indicated detectable relief of pain/tenderness or decrease in bleeding.61
*Median of 2.0 infusions to resolve a joint bleed; infusions given at intervals of 2.5 hours.
For Surgery in Hemophilia A or B with Inhibitors
- Recombinant Factor VIIa is 96% effective at controlling bleeding during surgery.68
- Recombinant Factor VIIa is effective in both major and minor surgery.68
Efficacy for 5 days after surgeryc
Adapted from Shapiro et al.68
Data from a prospective, randomized, double-blind trial of 2 doses (35mcg/kg or 90 mcg/kg) of recombinant Factor VIIa in patients with hemophilia A or B with inhibitors (N=24) undergoing minor or major surgery. Efficacy defined as follows: intraoperative bleeding: as expected or less than expected; 0-48 hours after wound closure: bleeding stopped or reduced; days 3-5: adequate control of bleeding.
c Charts show data for recommended dose in the Prescribing Information for NovoSeven® RT (90 mcg/kg). See Dosing for more detailed dosing information.
For Congenital Factor VII Deficiency
Recombinant Factor VIIa is 93% effective in stopping nonsurgical and surgical bleeds in people with congenital Factor VII deficiency.85
Efficacy in people with congenital Factor VII deficiency
In nonsurgical bleeding episodes:
- Efficacy appeared to be independent of the location of bleeding60
- Recombinant Factor VIIa proved effective across a range of serious bleeds60
For Surgery in FVII Deficiency
Treatment with rFVIIa was rated as effective in 37 of 43 (86%) of non-surgical bleeding episodes and in all surgical procedures for which data were collected (25/26, 96%).60
For Acquired Hemophilia
NovoSeven® RT is effective for acquired hemophilia
Efficacy with Recombinant Factor VIIa treatment90
Adapted from Sumner et al.90
Data were extracted from a review of experiences with recombinant Factor VIIa for the treatment of acquired hemophilia from the recombinant Factor VIIa compassionate use programs, the HTRS registry, and independent published reports. Efficacy was defined by the mean time to treatment from bleeding onset to first recombinant Factor VIIa dose as determined in non-surgical bleeding episodes and is shown in the chart above for “effective” and “partially effective” treatment outcomes. “Ineffective” treatment was determined by inability to stop the bleeding episode or by the physician describing treatment as not effective.50
