Based upon the results of the study, the company expects to complete the trial and file for regulatory approval late in 2014. Baxter is also initiating a continuation study for all patients who complete the pivotal Phase II/III study, and expects to initiate a study of BAX 855 among pediatric patients in 2014.
The treatment protocol is based on the results of a Phase I trial of BAX 855, assessing its safety, tolerability and pharmacokinetics. That trial found that the half-life (measuring the duration of activity of the drug in the body) of the investigational compound was approximately 1.5-fold higher compared to ADVATE. An extended half-life was achieved in all patients in the study using BAX 855, no patients developed inhibitors to either the base molecule, BAX 855 or to PEG, and no patients had allergic reactions. No treatment-related or serious adverse events were reported, and no patients withdrew from the study due to adverse events.
BAX 855 is built from the same native FVIII protein used in the production of ADVATE, and employs proprietary PEGylation technology from Nektar Therapeutics (NASDAQ: NKTR) designed to extend the duration of activity of proteins. PEGylation technology has been widely used in various approved treatments.
ADVATE [Antihemophilic Factor (Recombinant) Plasma/Albumin-Free Method] is indicated for the control and prevention of bleeding episodes in adults and children (0-16 years) with hemophilia A. ADVATE 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 not indicated for the treatment of von Willebra
