Filter by:This trial is conducted in Asia, Europe, and North and South America. The aim of this clinical trial is to investigate the safety and efficacy of turoctocog alfa (recombinant factor VIII, rFVIII (N8)) in male previously treated paediatric subjects with haemophilia A.
This trial is conducted in Europe. The aim of this clinical trial is to compare the metabolism of a blood-clotting drug (recombinant Factor XIII)) produced by two different manufacturers (Novo Nordisk and Avecia) in healthy male volunteers.
The study will assess the pharmacokinetics (part A) safety, tolerability, and efficacy of prophylaxis treatment (2 to 3 times a week) (part B) with BAY81-8973 over a one year period (split into two six month treatment periods). The study will compare 2 different methods (assays) for measuring the amount of study drug, the chromogenic substrate assay per European Pharmacopeia (CS/EP) with the classical assay (Chromogenic Substrate Adjusted, CS/ADJ). During one six month period patients will receive the study drug where the dose has been measured using the" (CS/EP) and during the other six months period the dose will be measured based on the Chromogenic Substrate Adjusted assay CS/ADJ)
The purpose of this study is to find out, whether filtration of the blood in patients undergoing cardiac surgery, beneficially influences the coagulation system.
Thoracoabdominal aneurysm (TAAA) repair is a major elective vascular operation associated with a large blood loss and potentially life-threatening clotting abnormalities. Theses clotting abnormalities are principally treated using fresh frozen plasma (FFP) (derived from human blood donations), the administration of which carries a number of risks including virus transmission (human immunodeficiency virus (HIV), hepatitis B, hepatitis C) and infection with variant Creutzfeld-Jacob disease (vCJD). FFP is no longer administered to children or high-usage adults in the UK because of the infection risk, and recently it was decided by a UK advisory body that the use of UK-derived FFP should cease. Fibrinogen concentrate is an alternative treatment option to FFP which is thought have less infection risk (purified, heat treated) and has been in licensed use for many years in other European countries. The investigators have been using fibrinogen concentrate recently in their department as an alternative to FFP with encouraging results. 20 patients undergoing elective TAAA repair at The Royal Infirmary of Edinburgh will be randomly allocated to receive standard treatment (FFP) or fibrinogen concentrate as treatment for clotting abnormalities during their surgery. The investigators will take a number of additional blood samples which will provide valuable information about the pattern of clotting abnormalities during this type of operation. The investigators will also record blood loss and the number of allogeneic (derived from human donors) blood components transfused to the patient (red cells, FFP and platelets). Our primary objective is to assess the pattern of coagulation abnormalities in both groups. We will also examine whether the use of fibrinogen concentrate during TAAA repair avoids the need to administer FFP.
This trial is conducted in Asia, Europe, Japan, Oceania, North America and South America. The aim of the trial is to investigate the safety and efficacy of turoctocog alfa (N8) in Haemophilia A patients. The trial is an extension to trials NN7008-3543 (start: March 2009, stop: September 2011) and NN7008-3545 (start: May 2010, stop: November 2011) and the pharmacokinetic trials NN7008-3600 (start: November 2010, stop: October 2011), NN7008-3893 (start: June 2011, stop: September 2011) and NN7008-4015 (start: August 2012, stop: March 2013).
This trial is conducted in Asia, Europe and North America. The aim of the trial is to investigate the safety of monthly replacement therapy of recombinant factor XIII in patients with congenital FXIII deficiency. The trial continues until the product is commercially available, but an interim assessment will take place when all subjects have completed 52 weeks in the trial.
The aim of this international prospective post-marketing surveillance study is to obtain data on treatment procedures, long-term safety and efficacy and patient acceptance of KOGENATE Bayer/FS in treatment of patients with haemophilia A under daily-life treatment conditions.
Background: Whether the management of vitamin K antagonists (VKA) therapy by general practitioners with the collaboration of anticoagulation clinics (ACC) provides better clinical outcomes than that accomplished by general practitioners alone (usual care [UC] management) is not clear. Objectives: To compare ACC-based shared-care management with UC management of VKA therapy with respect to clinical events. Patients/Methods: Open, randomized, multicenter study in patients starting VKA therapy for at least three months. The primary study outcome is a composite of confirmed symptomatic thromboembolic or major bleeding events. All-cause mortality is a secondary outcome. All outcomes are reviewed by a central, independent adjudication committee.
The purpose of this study is to explore how knowing genes that individuals inherit from their parents can make warfarin dosing more safe and effective. This study is being done to determine whether providing doctors with data on the genes their patients inherited and warfarin dosing recommendations based on those genes affects the costs and outcomes of care and after hospitalization for patients from different ethnic/racial backgrounds, and how physicians use this information in decision making.
