Summary
The study investigates how well the medicine called turoctocog alfa pegol (N8-GP) works in previously treated Chinese patients with severe haemophilia A.
Participants will be treated with N8-GP. This is a medicine that doctors can already prescribe in other countries.
The medicine will be injected into a vein (intravenous injections) and blood samples will be collected.
The study will last for about 7-8 months. Participants will have between 8 and 15 visits to the clinic and possibly a number of phone calls with the study doctor.
Eligibility Criteria
Inclusion Criteria
- Informed consent obtained before any trial-related activities. Trial-related activities are any procedures that are carried out as part of the trial, including activities to determine suitability for the trial.
- Male Chinese patient with severe congenital haemophilia A with a FVIII activity below 1% according to medical records.
- Aged greater than or equal to 12 years at the time of signing informed consent.
- History of at least 150 exposure days (EDs) to other FVIII products.
- The patient and/or caregiver is capable of assessing a bleeding episode, keeping a diary, performing home treatment of bleeding episodes and otherwise following the trial procedures at the discretion of the investigator.
Exclusion Criteria
- Known or suspected hypersensitivity to trial product or related products.
- Previous participation in this trial. Participation is defined as signed informed consent.
- Participation in any clinical trial of an approved or non-approved investigational medicinal product within 5 half-lives or 30 days from screening, whichever is longer.
- Known history of FVIII inhibitors based on existing medical records, laboratory report reviews and patient and/or caregiver interviews.
- Current FVIII inhibitors greater than or equal to 0.6 BU.
- Congenital or acquired coagulation disorder other than haemophilia According to medical records.
- HIV positive, defined by medical records, with CD4+ count less than or equal 200/L and a viral load greater than 200 particles/μl or greater than 400000 copies/mL within 6 months of the trial entry. If the data are not available in medical records within last 6 months, then the test must be performed at screening visit.
- Previous significant thromboembolic events (e.g. myocardial infarction, cerebrovascular disease or deep venous thrombosis) as defined by available medical records.
- Hepatic dysfunction defined as aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) greater than 3 times limit of normal combined with total bilirubin greater than 1.5 times the upper limit of normal at screening, as defined by central laboratory
- Renal impairment defined as estimated glomerular filtration rate (eGFR) below or equal to 30 mL/min/1.73 m^2 for serum creatinine measured at screening, as defined by central laboratory.
- Platelet count below 50×109/L at screening based on central laboratory values at screening.
- Ongoing immune modulating or chemotherapeutic medication.
- Any disorder, except for conditions associated with haemophilia A, which in the investigator's opinion might jeopardise the patient's safety or compliance with the protocol.
- Mental incapacity, unwillingness or language barriers precluding adequate understanding or cooperation.
