Details and patient eligibility

About

This trial is conducted in Asia, Europe and the United States of America (USA). The aim of the trial is to evaluate safety of immune tolerance induction (ITI) treatment with turoctocog alfa (a recombinant factor VIII) in patients who have developed neutralising antibodies against factor VIII after exposure to subcutaneous turoctocog alfa pegol during participation in NN7170-4213 (NCT02994407)

Inclusion criteria

Previous participation in the NN7170-4213 trial (male, age at least 18 years (part A) and age at least 12 years (part B))
Development of a confirmed high titre neutralising antibody towards factor VIII (greater than 5 Bethesda Unit) after exposure to subcutaneous turoctocog alfa pegol in the NN7170-4213 trial or development of a confirmed clinically relevant low titre inhibitor (at least 0.6 to below or equal to 5 Bethesda Unit), defined as factor VIII activity measures (recovery) and/or bleedpattern indicating a lack of clinical response to factor VIII treatment

Exclusion criteria

Known or suspected hypersensitivity to trial product(s) or related products, defined as allergic reactions
Participation in another clinical trial within 1 month before screening (except participation in NN7170-4213)
Any disorder, except for conditions associated with Haemophilia A which in the investigator's opinion might jeopardise patients' safety or compliance with the protocol
Currently receiving immune tolerance induction treatment with a factor VIII containing product other than turoctocog alfa
