An event is serious (based on the ICH definition) when the patient outcome is:
* congenital anomaly
* other medically important event
A 6-year-old boy developed intra-atrial thrombosis during prophylactic treatment with factor VIII inhibitor bypassing fraction and recombinant factor VIIa while on immune tolerance induction [ITI; routes and times to reaction onset not stated].
The boy, who had severe haemophilia A and high-titre inhibitor, had been undergoing ITI with a high dose of efmoroctocog-α [recombinant factor VIII (FVIII; recombinant Fc fusion protein)]. Subsequently, he developed a central venous access device (CVAD)-associated bacteraemia. He had been receiving prophylactic factor VIII inhibitor bypassing fraction [activated prothrombin complex concentrate] 100 units/kg/dose 1−2 times daily along with recombinant factor VIIa 200 μg/kg/dose for breakthrough bleeds through a port CVAD while on ITI....
