The recently published article describes interim results for 66 PUPs treated for at least 20 EDs, the time by which most inhibitors arise. The cumulative incidence (95% confidence interval) was 20.8% (10.7–31.0) for all inhibitors and 12.8% (4.5–21.2) for high-titre inhibitors. The study reported excellent efficacy of Nuwiq® in the prevention of bleeds, with median annual bleeding rates of 0 for spontaneous bleeds and 2.40 for all bleeds. Nuwiq® was also efficacious for the treatment of bleeds (92.4% of bleeds were controlled with one or two infusions) and as surgical prophylaxis (rated as “excellent” or “good” for 89% of surgical procedures). These interim results confirm the excellent haemostatic efficacy reported with Nuwiq® in previously treated patients.
Larisa Belyanskaya, Head of IBU Haematology, said: “We are very excited by the results of the NuProtect study and pleased that these interim data are now available as a publication in the specialist peer-reviewed journal Haemophilia. This is the first study to report data from PUPs treated with a rFVIII produced in a human cell line, and the results further differentiate Nuwiq® from other products on the market.”
Olaf Walter, Board Member at Octapharma, added that “These data demonstrate low immunogenicity of Nuwiq® in PUPs, the patient group at the greatest risk of inhibitor development, and confirm the excellent efficacy observed in previously treated patients. This publication is a further important step towards Octapharma’s goal of enabling patients with coagulation disorders to live a normal life.”
Octapharma would like to thank everyone involved in the study, in particular the patients and their families, without whom this research would not be possible.
About the NuProtect (GENA-05) study
The NuProtect clinical study (NCT01712438) is a phase 3, open-label, interventional clinical study being conducted across 38 centres, to evaluate at least 100 previously untreated patients (PUPs) with severe haemophilia A of all ages and ethnicities enrolled for study up to 100 exposure days (EDs) or 5 years maximum. Patients treated previously with any FVIII concentrates/blood products containing FVIII are excluded. The primary objective is to assess the immunogenicity of Nuwiq® by determining inhibitor activity using the Nijmegen-modified Bethesda assay at a central laboratory. Final data from the NuProtect study are expected to become available in 2019. More information on this trial is available at www.clinicaltrials.gov. An extension study (GENA-15, NCT01992549) will further evaluate the long-term immunogenicity, efficacy and safety of Nuwiq® in PUPs.
About Nuwiq®
Nuwiq® is a 4th generation rFVIII protein1, produced in a human cell line without chemical modification or fusion with any other protein2. Nuwiq® is cultured without additives of human or animal origin2, is devoid of antigenic non-human protein epitopes3 and has a mean half-life of 17.1 hours4,5 and a high affinity for the von Willebrand coagulation factor6. Nuwiq® treatment has been assessed in seven completed clinical trials which included 201 PTPs7,8 (190 individuals) with severe haemophilia A, including 59 children9. Nuwiq® is approved for use in the treatment and prophylaxis of bleeding across all age groups of PTPs with haemophilia A in the EU, US, Canada, Australia, Latin America and Russia. Further worldwide submissions for Nuwiq® are planned.

About Haemophilia A
Haemophilia A is an X-linked hereditary disorder caused by FVIII deficiency which, if left untreated, leads to haemorrhages in muscles and joints and consequently to arthropathy and severe morbidity. FVIII replacement prophylactic treatment reduces the number of bleeding episodes and the risk of permanent joint damage. This disorder affects one in every 5,000 to 10,000 men worldwide. Globally, 75% of haemophilia cases are left undiagnosed or untreated. The development of neutralising FVIII antibodies (FVIII inhibitors) against infused FVIII represents the most serious treatment complication. The cumulative risk of FVIII inhibitor development is reported to be currently up to 39%.
