Through a collaboration with Nektar Therapeutics (NASDAQ: NKTR), BAX 855 leverages proprietary PEGylation technology designed to extend the duration of activity of proteins. The technology has been shown to be safe and tolerable, and is used in various approved treatments.A Phase II/III multi-center, open-label study called PROLONG-ATE will be initiated in the United States during first quarter of 2013 with more than 100 previously treated adult patients with severe hemophilia A to assess the efficacy, safety and pharmacokinetics of BAX 855 for prophylaxis and on-demand treatment of bleeding. Information and enrollment details for the trial are available at www.clinicaltrials.gov or by emailing email@example.com. About ADVATE ADVATE [Antihemophilic Factor (Recombinant) Plasma/Albumin-Free Method] was initially approved by the FDA in July 2003 for control and prevention of bleeding episodes in adults and children (0-16 years) with hemophilia A. ADVATE is a full-length (derived from the complete FVIII gene) recombinant FVIII product that is processed without any blood-based additives. Because no blood-derived components are added at any stage of the manufacturing process, the potential risk of transmitting pathogens that may be carried in blood-based additives is eliminated. There have been no confirmed reports of transmission of HIV, HBV or HCV with rFVIII therapies. ADVATE is approved in 58 countries worldwide including the United States, Canada, 27 countries in the European Union, Argentina, Australia, Brazil, Chile, China, Colombia, Croatia, Ecuador, Hong Kong, Iceland, Iraq, Japan, Kuwait, Macau, Malaysia, Mexico, New Zealand, Norway, Panama, Puerto Rico, Serbia, Singapore, South Korea, Suriname, Switzerland, Taiwan, Ukraine, Uruguay, and Venezuela. In the United States, ADVATE [Antihemophilic Factor (Recombinant) Plasma/AlbuminFree Method] is also indicated for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children (0-16 years) with hemophilia A. ADVATE is the only antihemophilic recombinant FVIII treatment approved in the United States for prophylactic use in both adults and children. ADVATE is not indicated for the treatment of von Willebrand disease.
