Clinical trials

This research program is initiated to evaluate and document data on the success of ITI in 300 haemophilia A patients with newly developed or already existing FVIII-inhibitors (also patients who might potentially have failed in earlier ITIs), which will be treated with ITI - preferably high-dose based on individualized product selection, in order to improve management of this potentially devastating complication of haemophilia treatment. In order to investigate the role of in vitro tests on individual ITI success rate in patients undergoing ITI, the inhibitor plasma samples can be assayed against different FVIII concentrates using the following in vitro tests: Batch selection, Thrombin generation assay (TGA), Thrombin Generation Test (TGT) to monitor FVIII efficacy, Epitope mapping,IgG Subclasses specific for FVIII, Immunogenotyping.
