Filter by:This study is designed to evaluate the safety, tolerability and efficacy of long-term treatment with PF-06741086 in subjects with severe hemophilia who participated in the 3-month Phase 1b/2 B7841002 study. Additionally, de novo subjects will be recruited into this study.
This Phase IV, multicenter study will evaluate whether participants with Hemophilia A (PwHA) with or without inhibitors receiving emicizumab prophylaxis can safely undergo minor surgical procedures without additional prophylactic bypassing agents (BPA; for participants with inhibitors) or factor VIII (FVIII; for participants without inhibitors).
Prenancy and specialy delivery for hemophilia mother and her children possibly hemophilia is risked. Diagnostical of hemophilia pregnan is the first difficulty but patients with hemorrhagic menstruation without etiology known, hemorrhagic complication during a chirurgical procedure or during previously pregnancy currently are examine in Haemostasis consultation. None French recommendation specifie for health practice of these hemophilia patients exists. However, Anglo-Saxon recommendations are published in 2011. The objective of this study is to realize a French investigation of health practice about hemophilia care of these patients and to compare them with the English reference table.
This is a prospective, non-randomized, controlled study to examine whether or not having a higher trough during prophylactic treatment with clotting factor offers better joint protection than the standard trough of 1% Factor IX (FIX or Factor 9). This study will test the hypothesis that an extended half-life (EHL) FIX product with an intended trough of >10% could offer better protection than previous treatment concentrates. This study also examines whether or not joint damage could be diagnosed earlier using ultrasound images.
Uncontrolled, multi-centre, non-interventional study with a prospective and a retrospective cohort, to evaluate the efficacy of Wilate or Nuwiq in achieving complete or partial immune tolerance induction (ITI) success in severe and moderate haemophilia A patients with inhibitors
The WBDR is an international observational disease registry of patients with hemophilia. It will provide a platform for a network of hemophilia treatment centres (HTCs) around the world to collect uniform and standardized patient data and guide clinical practice. With informed consent from the patient, the WBDR stores anonymous data about the person's disease, such as hemophilia type and severity, symptoms, and treatment.
This multicenter, open-label, Phase 3 study with randomized and non-randomized arms is designed to investigate the efficacy, safety, and pharmacokinetics of emicizumab in participants with hemophilia A regardless of factor VIII (FVIII) inhibitor status. Participants greater than or equal to (≥)12 years old who received episodic therapy with FVIII or bypassing agents prior to study entry and experienced at least 5 bleeds over the prior 24 weeks will be randomized in a 2:2:1 ratio to the following regimens: Arm A: Emicizumab prophylaxis at 3 milligrams per kilogram (mg/kg) once every week (QW) subcutaneously (SC) for 4 weeks, followed by 1.5 mg/kg QW SC; Arm B: Emicizumab prophylaxis at 3 mg/kg QW SC for 4 weeks, followed by 6 mg/kg once every 4 weeks (Q4W) SC; and Arm C: No prophylaxis (control arm). In addition, pediatric participants less than (<)12 years old with hemophilia A and FVIII inhibitors who received episodic therapy with bypassing agents prior to study entry will be enrolled to Arm D: Emicizumab prophylaxis at 3 mg/kg QW SC for 4 weeks, followed by 1.5 mg/kg QW SC.
This study is aims at determining the inter laboratory variation when using the thrombin generation assay calibrated automated thrombogram (TGA CAT). It is thus, not a clinical trial in its usual meaning. However, to achieve relevant test samples one patient will be treated with two different study drugs as part of the trial and therefore, approval by Läkemedelsverket is needed. Test plasma samples will be sent out to five participating centers in the Scandinavian countries (Gothenburg and Stockholm, Sweden, Århus Denmark, Oslo Norway and Helsinki Finland) and coefficients of variance (CV) and level of agreement will be analyzed. To obtain representative plasma samples with a wide range of thrombin generation capacity (TGC), blood samples will be collected from research persons that has given informed consent to participate in the study. To obtain plasma with low TGC, blood samples will be drawn from patients with severe hemophilia (n=4)(study group 1), to obtain plasma with normal TGC, blood samples will be drawn from healthy volunteers (n=3)(study group 2) and to obtain plasma with high TGC, plasma will be collected from healthy volunteers (n=3)(study group 3) that at previous measurements have been shown to have a TGC>2SD of the median of the control population. Moreover, one patient with severe hemophilia A (HA) will be treated with two factor FVIII concentrates, one with standard half- life (Advate™) and one with a pro-longed half-life (Adynovate™) at two separate occasions (Treated HA person). By taking repeated blood samples after administration, samples with a wide range of FVIII levels and TGC:s will be obtained. Moreover, the effect of using plasmas with low, normal and high TGC for normalization will be investigated. Plasma samples will be collected as soon as approval from the Swedish medical agency (SMA) has been obtained, we count on sending them to participating centers March 2017. All laboratory measurements, data analysis and report writing will be concluded before December 31 2017.
Long-term safety and efficacy follow-up for participants with Hemophilia B who were previously treated in the C0371005 (formerly SPK-9001-101) study, and a dose-escalation sub-study evaluating safety, tolerability, and kinetics of a higher dose with long-term safety and efficacy follow-up. Participants in the substudy do not need to have participated in C0371005.
Severe haemophilia and subsequent arthropathy result in joint pain, disability and impaired health-related quality of life. Improvements in haemophilia care over the last decades might lead to expectation of a near-normal quality of life for adults with haemophilia. However, little is known about the impact of haemophilia and its treatment on social functioning. A study based on a national US cohort of 141 young men (18-34 y.o.) showed that, compared to the general US population, this cohort experienced social burdens such as unemployment and lower high-school graduation rates. Another study conducted in the framework of the HERO (Haemophilia Experiences, Results and Opportunities) international initiative showed that a majority of the 230 young adults aged 18-30 years (including 16 French participants) were employed at least part-time (62%) and most of them reported that haemophilia has had a negative impact on employment (76%) which was reported as moderate or very large by 47% of the participants. The replicability of these results could be limited by the specific socio-economic national context. In France, a survey was conducted in 2008 to assess quality of life and its determinants in children, adolescents and adults with moderate and severe haemophilia. Descriptive results on the socio-economic characteristics of the included adults showed that 51.3% of them had access to higher education (which was higher than the observed rate in the French general population in 2005, i.e. 32.5%), and that 52.1% were employed among whom 44.3% had an at-risk activity. In spite of these results which were presented in a descriptive report by the InVS (Institut de veille sanitaire - French Institute for Public Health Surveillance), some limitations could be discussed:
