Title: Efficacy and safety of recombinant factor VIII products in patients with hemophilia A. Author: Musso R. Journal: Drugs Today (Barc); 2008 Oct; 44(10):735-50. PubMed ID: 19137127. Abstract: The introduction of recombinant factor VIII (rFVIII) clotting factor concentrates nearly 20 years ago represented a significant advance in the treatment of hemophilia A. The major advantage of rFVIII products compared with plasma-derived FVIII products is related to product safety, with rFVIII products virtually eliminating bloodborne pathogen transmission. The most challenging aspect of hemophilia A management today is the development of FVIII inhibitors; previously untreated patients are at the highest risk for inhibitor formation. Presented in this article are results of clinical trials in previously treated and untreated patients and postmarketing surveillance studies for the four commercially available rFVIII products (Recombinate, ReFacto, Kogenate FS/Kogenate Bayer and Advate). Recombinant FVIII therapies are highly efficacious when used ondemand and prophylactically, and they have excellent safety profiles; there have been no reports of viral- or prion-based disease transmission associated with rFVIII administration. The incidence rate of inhibitors in previously untreated patients ranges from 15% to approximately 30%. Because rFVIII concentrates have proven efficacy and safety profiles, a number of hemophilia treatment groups recommend rFVIII products as first-line therapy in the management of hemophilia A.[Abstract] [Full Text] [Related] [New Search]
