Arm Description

Haemophilia A (HA) and haemophilia B (HB) patients, previously treated on-demand, will be randomised 1:2 to no prophylaxis versus concizumab prophylaxis. In the extension phase, this group will receive treatment with concizumab.

HA and HB patients, previously treated on-demand, will be randomised 1:2 to no prophylaxis versus concizumab prophylaxis.

The HA patients enrolled into the concizumab phase 2 trial NN7415-4255 (explorer 5) will be offered enrolment into this arm.

Arm 4 will include patients previously on prophylaxis with factor products with a minimum of 24 weeks observation in NN7415-4322 (explorer 6) (at least 30 HA and 30 HB patients). In addition, arm 4 will also include: 1) Patients who were randomised to arms 1 and 2 before the treatment pause. 2) HA patients who were in NN7415-4255 (explorer 5) at the time of the treatment pause, and who have now completed explorer 5. 3) On demand patients included after arms 1 and 2 are closed.

5. Study Description

Brief Summary
This study will test how well a new medicine called concizumab works in the body of people with haemophilia A or B without inhibitors. The purpose is to show that concizumab can prevent bleeds in the body and is safe to use. Participants who usually only take medicine to treat bleeds (on-demand) will be placed in one of two groups. In one group participants will get study medicine from the start of the study. In the other group participants will continue with their normal medicine and get study medicine after 6 months. Which treatment the participant gets is decided by chance. Participants who usually take medicine to prevent bleeds (prophylaxis treatment) or who are already being treated with concizumab (study medicine) will receive the study medicine from the start of the study. Participants will have to inject themselves with the study medicine 1 time every day under the skin. This can be done at home. The study doctor will hand out the medicine in the form of a pen-injector. The pen-injector will contain the study medicine. The study will last for up to 6.5 years. The length of time the participant will be in the study depends on when they agreed to take part or when the medicine is available for purchase in their country (21 April 2026 at the latest). Participants will have to come to the clinic for up to 40 times. The time between visits will be approximately 4 weeks for the first 6 to 12 months depending on the group participants are in, and approximately 8 weeks for the rest of the study. If the participant attends extra visits due to the prescription medicine not being available for purchase in their country, these will be 14 weeks apart. Participants will be asked to record information in an electronic diary during the study and may also be asked to wear an activity tracker.

Interventional Study Model
Parallel Assignment
Model Description
Patients will be randomised to concizumab PPX/no PPX/ assigned into non-randomised arms, based on treatment before trial. Upon restart, patients randomised to arms 1/2 before pause will enter arm 4. Patients allocated to arms 3 & 4 before pause will re-enter initially allocated arm. Randomisation into arms 1/2 will be restarted with new patients. Main part is completed when patient completed 24 wks (excluding screening) in arm 1 or 32 wks (excluding screening) in arms 2-4. After main part, patients will have offer to continue in extension (ext.) part and receive treatment with product until concizumab is commercially available in their countries or until 21-Apr-26 at latest. Patients will be in ext. part for up to 257 (arms 2-4) or 265 wks (arm 1) for up to additional 128 (arms 2-4) or 136 wks (arm 1). Patient will receive last dose at home on day prior to visit 26a. Follow-up part will start on visit 26a and lasts for 7 wks and include reporting of bleeding episodes until visit 27a.

Intervention Type
Drug
Intervention Name(s)
Concizumab
Intervention Description
When patients are randomised/allocated to concizumab prophylaxis, they will receive a loading dose of 1.0 mg/kg concizumab at visit 2a (week (Wk) 0) (arm 2, 3 and 4) or visit 9a (Wk 24) (arm 1) followed by an initial daily dose of 0.20 mg/kg concizumab from treatment day 2. Within an initial 5-8-week dose adjustment period on 0.20 mg/kg concizumab, the patients can be increased or decreased in dose to 0.25 mg/kg or 0.15 mg/kg concizumab. A potential dose adjustment will take place at visit 4a.1 (Wk 6) or 9a.3 (Wk 30) and will be based on the concizumab exposure level measured at the previous visit 4a (Wk 6) or 9a.2 (Wk 28). Patients who have concizumab exposure levels of 200-4000 ng/mL will stay at 0.20 mg/kg concizumab. Patients in arm 1 will continue on-demand treatment with their usual replacement therapy until visit 9a (week 24; end of main part). In the extension part, patients in arm 1 will receive daily concizumab subcutaneous injections.
