NovoSeven® resolved 96.5% of bleeds when initiated within one hour after bleed onset in people with haemophilia A or B with inhibitors

Novo NordiskNovo Nordisk has announced that NovoSeven® (rFVIIa), a portable room temperature stable recombinant activated factor VIIa, resolved 96.5% of bleeds when initiated within one hour after onset of bleeding, demonstrating efficacy of early treatment in people with haemophilia A or B with inhibitors.(1) Efficacy also remained high for bleeds treated after 4 hours. (1) A subanalysis of the SMART-7™ study, evaluating the efficacy of NovoSeven® in a real-world setting, was presented today at the 58th American Society of Haematology (ASH) annual meeting.

The SMART-7™ study examined the status of bleeding episodes across people with haemophilia divided into three groups by time to first treatment with NovoSeven® (≤1 hour, ˃1‒≤4 hours, ˃4 hours).(1) Across the three groups, 94.6% of bleeds were resolved while another 4.8% of bleeds were slowed.(1)

"Clinical guidelines recommend that acute bleeds in people with haemophilia should be treated within two hours of bleed onset," said Dr Gary Benson, SMART-7™ investigator, Northern Ireland Haemophilia Comprehensive Care Centre, Belfast City Hospital, Belfast, UK. "This study has shown that NovoSeven® has a favourable safety profile and can help people living with haemophilia to address bleeds quickly."

Efficacy results from this subgroup analysis of SMART-7™ are aligned with previous rFVIIa data.(2-7) Furthermore, no binding antibodies were associated with the room temperature stable formulation of rFVIIa under real-world conditions.

About SMART-7™
SMART-7™ (NCT01220141) was a prospective, post-authorisation, single-arm, multinational, multi-centre, non-interventional study investigating the safety and effectiveness of NovoSeven® (rFVIIa), a room temperature stable recombinant activated factor VIIa in people with haemophilia A or B with inhibitors in a real-world setting.(1)

A total number of 51 participants were enrolled across 14 countries. Participants were aged 1.6–69.5 years (median 22.0 years) with a historical median bleeding rate of one episode per month. The primary objective of the study was to monitor people with haemophilia A or B with inhibitors treated with NovoSeven® for a decreased therapeutic response.(1)

About NovoSeven® NovoSeven® is a recombinant activated factor VII (rFVIIa) and is indicated for the treatment of spontaneous and surgical bleedings in haemophilia A or B patients with inhibitors, acquired haemophilia, congenital FVII deficiency and Glanzmann's thrombasthenia (EU and US only).(8)

About haemophilia
Haemophilia is a chronic, inherited bleeding disorder that primarily affects males. People born with haemophilia have little or no clotting factor, which is a protein needed for normal blood clotting. The two main types of haemophilia are A and B; people living with haemophilia A lack clotting factor VIII and people living with haemophilia B lack clotting factor IX. Haemophilia A is about four times as common as haemophilia B.9 Inhibitor formation is the most serious complication in haemophilia A or B, rendering the patient unresponsive of replacement therapy with clotting factor VIII or IX. In that case, bypassing agents such as NovoSeven® are used.

Haemophilia can be mild, moderate or severe, depending on the amount of clotting factor in the blood. Approximately 400,000 people are estimated to live with haemophilia globally.(10)
