POCUS: Hemostatic Potential and Joint Health in Patients With Severe Hemophilia A on Novel Replacement Therapies
Study Details
- Hemophilia A
- Drug: Eloctate
- Drug: Adynovate
- Drug: Emicizumab
- Inclusion Criteria:
- Subjects with moderate hemophilia A (baseline factor VIII activity 1-5%) or severe hemophilia A (baseline factor VIII activity \<1%) on prophylactic standard half-life FVIII infusions OR subjects with moderate or severe hemophilia A who have not started prophylactic treatment
- Less than 18 years of age
- Exclusion Criteria:
- Subjects with documented FVIII inhibitor
- Subjects with a history of ≥ 2 target joints
- Subjects with a history of synovectomy
- Currently using medications known to impact bone and mineral metabolism (e.g., bisphosphonates, corticosteroids, estrogen, testosterone, calcitonin, thyroid hormone therapy);
- Disease states known to affect bone integrity (e.g., primary hyperparathyroidism, Paget's disease, clinically significant liver disease)
Protocol Summary
This study is looking at how safe it is to switch from emicizumab to Mim8, in people with haemophilia A. Mim8 is a new medicine that is used to prevent bleeding episodes in people with haemophilia A. Mim8 works by replacing the function of the missing clotting factor VIII (FVIII). Mim8 will be injected under the skin using a pen-injector either once every week, once every two weeks or once every month. The participants will be trained in using the pen injector. The participants can choose themselves, in collaboration with the study doctor how often they get Mim8 in this study. When the participant will get their first Mim8 injection depends on their current treatment with emicizumab. The participants will get their first Mim8 injection at Visit 2. Participants will have between 6 and 27 Mim8 injections. The total number of injections participants will have depends on their dosing frequency. The study will last for about 6-12 months. While taking part in this study, there are some restrictions about what medicine participant can use. The study doctor will tell the participants more about this. In case the participants experience bleeds, these can be treated with additional haemostatic medicine as agreed with the study doctor. Female participants cannot take part if they are pregnant, breast-feeding or plan to get pregnant during the study period.
