E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate safety of immune tolerance induction treatment with turoctocog alfa in patients who have developed neutralising antibodies against factor VIII after exposure to subcutaneous turoctocog alfa pegol during participation in NN7170-4213 |
|
E.2.2 | Secondary objectives of the trial |
To evaluate efficacy of immune tolerance induction treatment with turoctocog alfa |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Previous participation in the NN7170-4213 trial (male, age ≥ 18 years (part A) and age ≥ 12 years (part B)).
- Development of a confirmed high titre neutralising antibody towards factor VIII (>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 (≥0.6 to ≤5 Bethesda Unit), defined as factor VIII activity measures (recovery) and/or bleed pattern indicating a lack of clinical response to factor VIII treatment. |
|
E.4 | Principal 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. |
