Haemophilia, January 2017, 2017-Jan, 2017-01-00, 20170101, Letnik: 23, Številka: 1Journal Article
Introduction Patients with acquired haemophilia A (AHA) have autoantibodies against factor VIII (FVIII), and may develop spontaneous bleeding that requires treatment with FVIII inhibitor bypassing agents such as recombinant activated FVII (rFVIIa, NovoSeven®). However, data regarding the use of rFVIIa are limited. Aim To investigate the use, efficacy and safety of rFVIIa for the treatment of AHA by analysis of 10‐year multicentre Japanese postmarketing surveillance data. Methods Treatment regimens, haemostatic efficacy and adverse events were recorded for rFVIIa therapy of AHA patients with bleeding episodes. Treatment was evaluated as markedly effective, effective, moderate or ineffective. Results Data were collected for 371 bleeding episodes in 132 patients. Bleeding improved after rFVIIa therapy in 92% of episodes (markedly effective in 41%, effective in 10%, moderate in 41%). The response rate was significantly better in patients who received an initial dose of ≥90 μg kg−1 than in those who received an initial dose of <90 μg kg−1. The response rate was also significantly better when rFVIIa was administered earlier after the onset of bleeding. Twelve serious adverse events were recorded in six patients, including five serious thromboembolic events in three patients who were all elderly with significant comorbidities. Conclusion This is the largest, single‐country study of rFVIIa therapy in AHA patients reported to date. The Japanese surveillance data show comparable efficacy and safety to prior multinational studies. Doses of 90–120 μg kg−1 and prompt initiation of treatment may be important to achieve good bleeding control.
