Damoctocog alfa pegol
In recent years, various extended half-life factor VIII and factor IX preparations have been studied and gained approval. In order to extend half-lives, techniques such as fusion to protein conjugates (Fc part of IgG1 or albumin), chemical modification (PEGylation), and protein sequence modification have been utilized.  Also known as, BAY94-9027, Damoctocog alfa pegol is a longer-acting Factor VIII therapy formulated with polyethylene glycol (PEG) to reduce the number of infusions necessary to prevent bleeds in patients diagnosed with Haemophilia A. This product has been engineered by Bayer and a biological license application has been filed with the FDA in August 2017 and FDA approved in August 2018.
