INTRODUCTION Biogen Idec is the first biotechnology company to receive approval from the US Food and Drug Administration (FDA) for a long-acting recombinant coagulation factor IX product, that’s intended for use in patients with Hemophilia B (Christmas Disease). Approved under the proprietary name Alprolix, Coagulation Factor IX (Recombinant), Fc Fusion Protein is therapeutically designed to be prolonged in circulation and requires less recurrent injections by users. Alprolix is an innovation that is advancing treatments and the quality of life for patients with deficient or dysfunctional congenital Factor IX.

The cryoprecipitate is used for patients who don’t have enough or are unable to produce sufficient fibrinogen and clotting factor VIII. The FFP and cryoprecipitate can both be used for patients who have had a liver transplants and trauma cases in which the patients has clotting problems. The other products such as the immunoglobulin are used for fighting diseases because of the antibodies in the plasma. The anti-D is used in pregnancies in case of an RhD incompatibility between the baby and the mother; this stops the mother creating antibodies against the baby. The albumin and the clotting factors are used for patients who have a deficiency of these proteins.

In some individuals with severe hemophilia, the factor VIII replacement therapy is identified as a foreign substance by their immune system. If this happens, their immune system will make antibodies against factor VIII. These antibodies will inhibit the ability of the factor to work in the clotting process. The higher the antibody or inhibitor level, the more factor VIII replacement therapy it takes to overcome the inhibition and produce clotting. This can complicate the treatment of a bleed. The good news is that there are different types of therapies available to successfully treat most individuals who develop inhibitors.

The changes in f8 and f9 gene are responsible for hemophilia A and B. the f8 gene codes for a protein called coagulation 8. This protein is responsible for the blood clotting process. After an injury blood clots protect the body by sealing off the area of injury. Mutation in the f8 and f9 gene can lead to the abnormal form of the protein. Also can lead to a reduction of the coagulation pro...

Clinical trials containing new drugs are categorized into essential four phases (1). The drug development procedures are usually performed through the all phases over several years (1). The drug will be approved for use in the general population, if it successfully exceeds through the first three phases; I, II, and III. The fourth phase -IV- is called Post marketing Surveillance and/or Post approval studies (2). Postmarketing Surveillance Trial provides the safety surveillance (Pharmacovigilance) (3). phase IV Analytics methods studies may be required by sponsoring companies, when detecting a new drug market or testing the drug interactions with other drugs, and also by regulatory authorities (4). The safety surveillance, which is a very important part of a comprehensive post-marketing program, investigates drugs long term effects in a large number of people (1) (3).
