Abstract
Background: The bypassing agent, activated prothrombin complex concentrate [aPCC, FEIBA (factor VIII inhibitor bypass activity); Baxalta US Inc, a Takeda company, Lexington, MA, USA], is indicated for the treatment of bleeding episodes, perioperative management, and routine prophylaxis in patients with hemophilia A or B with inhibitors. In certain countries, aPCC is also indicated for the treatment of bleeding episodes and perioperative management in patients with acquired hemophilia A.
Objectives: To describe long-term, real-world effectiveness, safety, and quality-of-life outcomes for patients with congenital hemophilia A or B and high-responding inhibitors receiving aPCC treatment in routine clinical practice.
Design: FEIBA Global Outcome (FEIBA GO; EUPAS6691) was a prospective, observational study.
Methods: Investigators determined the treatment regimen and clinical monitoring frequency. The planned patient observation period was 4 years. Data are from the safety analysis set (patients who received ⩾1 aPCC infusion).
Results: Overall, 50 patients received either aPCC prophylaxis (n = 37) or on-demand therapy (n = 13) at screening [hemophilia A, n = 49; hemophilia B, n = 1; median (range) age, 16.5 [2-71] years). Mean ± standard deviation overall annualized bleeding rate and annualized joint bleeding rate for patients receiving prophylaxis were 6.82 ± 11.52 and 3.77 ± 5.71, respectively, and for patients receiving on-demand therapy were 10.94 ± 11.27 and 6.94 ± 7.39, respectively. Overall, 177 and 31 adverse events (AEs) were reported in 28 of 40 and 10 of 13 patients receiving prophylaxis or on-demand therapy, respectively. Two serious AEs were considered possibly related to aPCC: acute myocardial infarction due to coronary artery embolism in one patient receiving prophylaxis. No thrombotic microangiopathy was reported. No AEs resulted in death.
Conclusion: This study demonstrated the long-term, real-world effectiveness and consistent safety profile of aPCC as on-demand therapy and prophylactic treatment in patients with hemophilia and high-responding inhibitors.
