1.3% (4/320) of patients in Alhemo® clinical trials reported venous and arterial thromboembolic events. Cases occurred in patients with multiple risk factors for thromboembolism, including high doses or prolonged treatment with factor products or BPAs (2 of 4 events).

Safety established
in clinical trial program with studies including all hemophilia types1

patient-years of exposure


320

patients, including 133 males with inhibitors, received at least one dose of Alhemo® as routine prophylaxis

Adverse reaction data reflects exposure of 52 patients with HAwI and HBwI who were previously treated with on-demand therapy and who were randomized in explorer7 to arm 1 to receive on-demand treatment with BPAs (n=19) or arm 2 to receive Alhemo® PPx (n=33) at the recommended dosing regimen. The median duration of treatment was 31.1 weeks (range 3.9, 72.9 weeks) in arm 1 (on-demand arm) and 40.1 weeks (range 3.1, 56.3 weeks) in arm 2 (Alhemo® PPx).

The most frequently reported adverse reactions (incidence ≥5%) were injection site reactions (18%) and urticaria (6%).1,b

Majority of injection site reactions were mild.2

Dosage interruptions of Alhemo® due to an adverse reaction occurred in 1 patient (3%) and was a hypersensitivity reaction.1

aThe explorer7 and explorer8 clinical trials were temporarily paused because 3 patients experienced 5 nonfatal TEs. In response, a plan was put in place that included deploying a laboratory-developed test to measure concizumab-mtci levels in order to individualize dosing, as well as guidance around how to treat breakthrough bleeds.1,2
bInjection site reactions included: injection site bruising, injection site erythema, injection site hematoma, injection site hemorrhage, injection site reaction, and injection site urticaria.
Urticaria included: urticaria and injection site urticaria.
