Filter by:The trial is conducted in North America. The aim of the trial is to assess the safety of turoctocog alfa under conditions of routine clinical care in patients with haemophilia A in Mexico
Elocta (rFVIIIFc) and Alprolix (rFIXFc) are recombinant extended half-life coagulation factor products. The purpose of this non-interventional study is to describe the real-world usage and effectiveness of Elocta and Alprolix in the prophylactic treatment of haemophilia A and B.
The trial is conducted in Asia, Europe and North America. The aim of the study is to evaluate the safety of administration under the skin of turoctocog alfa pegol (SC N8-GP) in patients with severe haemophilia A.
This trial is conducted globally. The aim of this trial is evaluating the pharmacokinetics (the exposure of the trial drug in the body) of NovoEight® (turoctocog alfa) in relation to BMI (body mass index) in subjects with haemophilia A.
This trial is conducted in China. The aim of this trial is to evaluate the clinical efficacy of turoctocog alfa in treatment of bleeding episodes in Chinese patients with severe haemophilia A (FVIII≤1%).
Investigating single dose pharmacokinetics and safety of turoctocog alfa pegol from the pivotal process and turoctocog alfa pegol from the commercial process in patients with severe haemophilia A
This trial is conducted globally. The aim of this trial is to investigate safety, pharmacokinetics (the exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of concizumab administered subcutaneously to haemophilia A subjects.
Personalized therapy in haemophilia has not been reached yet. Treatment is substitutive and its doses are only based on the levels of deficient factor VIII (for haemophilia A) or IX (for haemophilia B). The bleeding severity is not only related to the factor deficiency but also to levels of other coagulation factors (e.g. factor X, II, AT or TFPI). It's necessary to take them into account in order to individualize treatments; and Thrombin Generation Assay (TGA) with the CAT method (Calibrated Automated Thrombography) is a good way because it measures the result of the coagulation cascade. TGA on Platelet Rich Plasma (PRP) is even closer to physiological conditions than on Platelet Poor Plasma (PPP) because platelet influence is represented. It has already been shown (at least in PPP) that the bleeding tendency in haemophilic patients is usually well correlated to TG. Some TG parameters are used to characterize the individual coagulation phenotype, the most important being the Endogenous Thrombin Potential (ETP) and the Lag Time (LT). A hemorrhagic profile usually provides a longer lag time and / or a lower ETP. However, only few studies tried to determine the influence of each coagulation factor and inhibitor on TG. They were done on Platelet Poor Plasma (PPP) or on lyophilized plasma. So the relation between coagulation factors and the different TG parameters remains to be determined, especially in the haemophilic case. It is possible, experimentally, to find the optimal dose of the factor to be added by measuring TG in samples with different factor VIII or IX concentrations, but this method would be time consuming and expensive, especially because it should be done for each haemophilic patient. A better way consists in using TG numerical models. For a set of initial factor levels they simulate the TG and its associated parameters. It is now essential to validate the existing models, especially in haemophilic cases, in order to see whether they are reliable and can be used in clinical practice afterwards.The objective of this study is to validate thrombin generation numerical models which could predict the factor VIII or IX activity correction to reach a thrombin generation sufficient to avoid bleeding. A comparison between the TG observed in haemophilic patients and the TG predicted by the models is needed to validate the models. In order to define a 'safe' TG i.e. sufficient to avoid bleeding, normal ranges of TG parameters have to be measured.
The main objective of the study is to investigate the safety and efficacy of Optivate®, administered in appropriate dosage to present bleeding and achieve haemostasis in patients with Haemophilia A undergoing surgery.
The main objectives of this study are: - to assess Optivate® consumption (IU/kg consumed per month for prophylactic and on-demand therapy and dose at each bleed). - to assess clinical outcome when treating a bleed with Optivate®. - to evaluate Optivate® in terms of clinical tolerance and safety in children under the age of 6 years. . - to assess FVIII inhibitor development during the study.
