Filter by:To provide emergency access to OBI-1 for patients with Acquired Hemophilia and a serious bleeding episode who do not have access to an active clinical study site associated with the OBI-1-301 study.
This study aims to investigate prospectively throughout a period of 3- 6 months and not to exceed 12 months (according to local therapeutic plans) patients experiences of treatment with Factor VIII in the new device named FuseNGO, a new delivery system for Factor VIII compared to their previous delivery system.
This study is conducted in Europe. The aim of the study is to update the knowledge about the prevalence and severity of congenital haemophilia (A and B) in Spain.
This trial is conducted in Europe. The aim of the trial is to investigate the pharmacokinetics (the exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of rFVIIa (activated coagulation factor VII) following one single injection of 270 microg/kg compared to three injections of 90 microg/kg rFVIIa in patients with haemophilia.
To continue the evaluation of the safety and efficacy of BAX 855 for prophylaxis and treatment of bleeding episodes in adult and pediatric previously treated patients (PTPs) aged ≤ 75 years of age with severe hemophilia A.
This is the first in humans study of BAY86-6150 (B0189) in non-bleeding subjects with moderate or severe congenital hemophilia A or B with or without inhibitors. This is a randomized, double-blind, placebo-controlled, single-dose, dose escalation study. It is designed to investigate the safety, tolerability, potential immunogenicity, pharmacokinetic and pharmacodynamic profile of BAY86-6150 (B0189) and to determine a dose or range of doses to be examined in subsequent studies.
The purpose of the study is to evaluate the efficacy and safety of BAX 855 in severe hemophilia A previously treated (PTP) males, 12 to 65 years of age who are undergoing elective surgical or other invasive procedures.
To compare the number of breakthrough bleeds under tailored prophylaxis with Human cell line recombinant factor FVIII (Human-cl rhFVIII) with the historical bleeding rate from patients who received Human-cl rhFVIII as on demand treatment.
Occurrence of inhibitors to coagulation factor VIII is diagnosed in ~30% patients with haemophilia A. Presence of inhibitor with a titre >5 BU/ml requires the use of by-passing agents: recombinant activated Factor VIIa concentrate (rFVIIa) and/or activated prothrombin complex concentrate (APCC). Similarly, haemorrhagic complications in patients with acquired haemophilia and inhibitor titre >5 BU/ml should be treated with by-passing agents. Response to treatment with by-passing agents is patient-specific, and can vary in the same patient during subsequent bleedings. Some patients have good response to both products, however in other patients a better bleeding control is provided by one of the mentioned above agents (APCC or rFVIIa). There are clinical situations when severe bleedings requires an alternate use of both these agents. Traditional methods of laboratory tests used post-treatment in patients with haemophilia without inhibitors are useless in the presence of inhibitor. Laboratory monitoring of therapy with by-passing agents is possible with the use of global tests for the coagulation process assessment, which are as follows: thrombin generation assay (TGA) and thromboelastometry (TEM). Several studies revealed that TGA allows a monitoring of therapy with by-passing agents in patients with haemophilia A and inhibitor - the choice of the most effective treatment option - agent type and its dose, as well as laboratory assessment of treatment efficacy. Up to date, laboratory tests assessing the efficacy of by-passing agents in patients with acquired haemophilia were not conducted. In Factor VIII or IX deficiency conditions, fibrin's fibres generated by thrombin are morphologically thicker, and blood clots have increased susceptibility to fibrinolytic enzymes. Blood clot stability may be assessed with the use of thromboelastometry (TEM). We can hypothesize that simultaneous use of TGA and TEM methods may allow for an assessment of patient's individual response to therapy with by-passing agents. Clinical significance of the minimal dose of APCC and rFVIIa, needed to TGA and TEM normalization, requires further studies. Tests' purpose: Examination of the hypothesis that simultaneous use of thrombin generation assay (TGA) and thromboelastometry (TEM) may facilitate the choice of optimal therapy with by-passing agents and laboratory monitoring of efficacy of those agents in patients with acquired haemophilia or haemophilia A with inhibitor.
This study is conducted in the United States of America (USA). The aim of this study is to assess the long-term (5+ years) postoperative functional outcomes of elective orthopaedic surgery (EOS) patients from previously reported studies F7HAEM/USA/3/USA and F7HAEM/USA/4/USA (NCT01561391) and furthermore to assess the impact of EOS on psychosocial outcomes, frequency of bleeding episodes and durability of joint surgery.
