Reproduction is authorised provided the source is acknowledged. 1. Background Today’s standard treatment of congenital haemophilia (and acquired haemophilia A) is based on prophylactic or on-demand replacement therapy with coagulation factor VIII (FVIII), either with plasma derived or with recombinant FVIII products. Principally both substance classes may be used for prophylactic treatment as well as for therapeutic treatment in case of spontaneous bleedings. Inhibitor development in haemophilia A patients receiving FVIII products mostly occurs in previously untreated or minimally treated patients (PUPs), who are still within the first 50 days of exposure to the treatment.

    AUSTRALIAN PRODUCT INFORMATION OBIZUR® (susoctocog alfa) 1 NAME OF THE MEDICINE Susoctocog alfa (bhk). 2 QUALITATIVE AND QUANTITATIVE COMPOSITION Each OBIZUR vial contains nominally 500 units (U) of susoctocog alfa, which is a B domain deleted recombinant derived antihaemophilic factor VIII (rpFVIII), porcine sequence. After reconstitution, OBIZUR contains nominally 500 U/mL susoctocog alfa. Each vial of OBIZUR is labelled with the actual rpFVIII activity expressed in units determined by a one-stage clotting assay, using a reference rpFVIII material calibrated against the World Health Organization (WHO) 8th International Standard for human factor VIII concentrates. The specific activity of OBIZUR is in the range of 11000 - 18000 Units per milligram of protein. The potency values of OBIZUR determined by the chromogenic assay vary and are approximately 20-50 % lower than those of the one-stage clotting assay. Susoctocog alfa is expressed in a genetically engineered baby hamster kidney (BHK) cell line and secreted into the cell culture medium, and the protein is purified using a series of chromatography and filtration steps. The production process includes two dedicated viral clearance steps - a solvent/detergent treatment step for viral inactivation and a nanofiltration step through a series of two 15-nm filters for removal of viruses. No additives of human or animal origin are used in the formulation of OBIZUR. Excipient(s) with known effect Each vial of OBIZUR contains maximally 4.4 mg (198 mM) sodium per mL of reconstituted solution (see Section 4.4 SPECIAL WARNINGS AND PRECAUTIONS FOR USE). For the full list of excipients, see Section 6.1 LIST OF EXCIPIENTS.

    Journal of Transfusion Medicine 2020, tom 13, nr 3, 186–194 DOI:10.5603/JTM.2020.0007 REVIEW ARTICLE Copyright © 2020 Via Medica ISSN 1689–6017 A practical approach to the patient with acquired haemophilia A in Poland Magdalena Górska-Kosicka1 , Michał Wójciak2 , Jerzy Windyga1, 3 1Department of Disorders of Hemostasis and Internal Diseases, Institute of Hematology and Transfusion Medicine in Warsaw 2Faculty of Medicine, Medical University of Warsaw 3Department of Hemostasis and Metabolic Diseases, Institute of Hematology and Transfusion Medicine, Warsaw Summary Acquired haemophilia (AHA) is a severe acquired bleeding disorder that develops due to circu- lating autoantibodies directed against coagulation factor VIII (FVIII). These antibodies inhibit the coagulation activity of FVIII in patient’s plasma. AHA is mainly diagnosed in the elderly and more than half of the cases are idiopathic. Underlying conditions which favor AHA oc- currence are — among others — autoimmune diseases, neoplasms, pregnancy and 12-month post-partum period. The clinical picture is dominated by extensive ecchymosis, less often by intramuscular and retroperitoneal haematomas or hemorrhages to the central nervous system. Laboratory findings include isolated prolonged activated partial thromboplastin time (APTT), decreased FVIII activity and the presence of a FVIII inhibitor. Although patients with AHA usually present with severe hemorrhagic disorders, asymptomatic forms may also occur, with accidentally detected prolonged APTT as the only abnormality. The aim of AHA management is bleeding control and eradication of inhibitor. Key words: acquired haemophilia A, factor VIII, bypassing agents, inhibitor, bleeding J Transf Med 2020; 13: 186–194 Introduction data however may be underestimated due to mis- diagnosis [2].
