Details and patient eligibility

About

This trial is conducted in Asia, Europe, Japan and North America. The aim of this clinical trial is to investigate the safety and the efficacy of a prophylactic treatment option with long acting coagulation factor VII (LA-rFVIIa) for haemophilia patients with inhibitors.

Enrollment

23 patients

Sex

Male

Ages

12 to 65 years old

Volunteers

No Healthy Volunteers

Inclusion criteria

Male haemophilia A or B patients with inhibitors
Willing to undergo a bleeding preventive regimen of 3 months' duration and a total trial length of approximately 8 months
Historical or ongoing high titre inhibitor (more than or equal to 5 BU) based on either medical records, laboratory report reviews, patient and/or care provider interviews
At least 2 bleeding episodes requiring bypassing haemostatic-drug-based treatment within the last month or 12 bleeding episodes within the last 6 months prior to observation period
Body weight between 30 and 100 kg (both inclusive)

Exclusion criteria

Body Mass Index (BMI) above 30 kg/m2
Immune tolerance induction therapy within the last month prior to entering observation phase period
Known active pseudo tumours
Platelet count less than 50,000 platelets/microL (based on local laboratory value at screening visit)
Congenital or acquired coagulation disorders other than haemophilia A or B
Surgery within one month prior to the observation period. Catheter, stents and dental extractions do not count as surgeries, i.e. they will not exclude the patient. Port insertion is classified as surgery
Scheduled major and/or orthopaedic surgery, during the trial period until Follow up visit. Catheter, stents and dental extractions do not count as surgeries and will not exclude the patient. Port insertion is classified as surgery
Advanced atherosclerotic disease (i.e. known history of ischemic heart disease, or ischemic stroke)
Any clinical signs or known history of thromboembolic events incl. known deep vein thrombosis (DVT)
Known or clinically suspected allergy to activated recombinant human factor VII (NovoSeven®/NovoSeven RT®/Niastase®)
Prothrombin Time (PT) prolongation (30% above normal limits, or more than 5 seconds compared to control or International Normalised Range (INR) more than 1.7 as defined by local laboratory ranges at screening visit
Severe liver disease (ALAT more than 4 times of the upper limit of normal reference range) (as defined by local laboratory ranges) within a year of enrolment or at the screening
Clinical signs of renal dysfunction (dialysis) and/or creatinine levels more than or equal to 20% above upper normal limit (according to local laboratory range at the screening visit)
Dosing of any investigational drug within the last 30 days prior to the present trial
Any disease or condition which, according to the investigator's judgement, could imply a potential hazard to the subject, interfere with the trial participation or trial outcome
HIV positive patients who either have low CD4+ lymphocyte count ( 200/microL or less based on medical records within 6 months or laboratory screening at screening visit), or who are HCV-PCR positive (based on medical records), or who both have low CD4+ lymphocyte count (200/microL or less) and are HCV-PCR positive. If HCV-PCR testing is not locally available, a HIV positive patient who is HCV antibody positive cannot be included
Need to use other PEGylated pharmaceutical drug during the trial period
