In another study involving 63 patients aged less than twelve years, children had an average of 5.33 bleedings per year after using turoctocog alfa as hemophilia treatment. In this study too turoctocog alfa was considered as an excellent treatment for 116 out of 126 bleeding episodes.Alongside the benefits, a few of the common turoctocog alfa adverse effects would be injection site reaction, pyrexia and augmented liver enzyme levels. Rare cases of allergic reactions have been reported as well. There is a possibility of patients developing hypersensitivity to the drug since it contains traces of hamster proteins. Activity-neutralising antibodies may be developed whereby expected plasma factor VIII activity levels may not be achieved and thus the bleeding would not be controlled as needed. Preparation
As cell culture, Chinese hamster ovary cells (CHO) are used in order to acquire proper processing of factor VIII protein, that has demonstrated good efficacy in thrombin generation and clot formation in preclinical evaluations in murine (mouse) and canine (dog) models of hemophilia A and in patient-derived whole blood. Difference between NovoSeven and NovoEight
Even though both treatments are plasma-derived and recombinant analogues of blood clotting factors, NovoSeven is developed as a congenital FVIIa analogue for hemophilia A and B patients while NovoEight (turoctocog alfa) is for congenital FVIII deficiency. NovoSeven is called a bypassing agent because it skips the need for factor VIII or IX in people with inhibitors and activates factor X directly.
Sebelipase alfa, sold under the brand name Kanuma,  is a recombinant form of  the enzyme lysosomal acid lipase (LAL) that is used as a medication for the treatment of lysosomal acid lipase deficiency (LAL-D). It is administered via intraveneous infusion. It was approved for medical use in the European Union and in the United States in 2015. Medical uses
Sebelipase alfa is indicated for long-term enzyme replacement therapy (ERT) in people of all ages with lysosomal acid lipase (LAL) deficiency. History
Sebelipase was developed by Synageva that became part of Alexion Pharmaceuticals in 2015. For its production, chickens are genetically modified to  produce the recombinant form of LAL (rhLAL) in their egg white. After extraction and purification it becomes available as the medication. On 8 December 2015 the FDA announced that its approval came from two centers: The Center for Drug Evaluation and Research (CDER) approved the human therapeutic application of the medication, while the Center for Veterinary Medicine (CVM) approved the application for a recombinant DNA construct in genetically engineered chicken to produce rhLAL in their egg whites. At the time it gained FDA approval Kanuma was the first only drug manufactured in chicken eggs and intended for use in humans.Sebelipase alfa is an orphan drug; its effectiveness was published after a phase 3 trial in 2015. The disease of LAL affects < 0.2 in 10,000 people in the EU. References
