Filter by:Life expectancy of haemophilia patients (specially severe) has dramatically increase in the last decades, which lead to the apparition of aging diseases such as cardiovascular disease, with the potential bleeding risk of antiplatelet therapies and anticoagulants. The primary endpoint of the study is to evaluate this bleeding risk in haemophilia patients (all severity) with such treatment in comparison to non treated patients, according to the number of bleeding events in the last year reported by the haemophilia patients under study treatment (antiplatelet and anticoagulant) in comparison to haemophilia patients free of such treatment. The main hypothesis is that antiplatelet and anticoagulant therapy can be safely used in minor haemophilia patients but might lead to increase bleeding risk in other haemophilia patients. Secondary endpoint consist in: - Evaluate the impact of know cardio-vascular risk in haemophilia patients (Odd ratios=OR) - Evaluate the number of sever bleeding event in patient under study treatments compared to the control group - Evaluate the overall consumption of factor VIII or IX supply in patients under study treatments compared to control group - Estimate the stenosis relapse risk in haemophilia patients with arterial STENT - Estimate the embolic risk of haemophilia patients with atrial fibrillation Population description: Haemophilia patients (man, all severity) Age above 50 years, followed during the last 5 years in one of the study centre
This open-label, multicenter expanded access program (EAP) is designed to provide emicizumab to eligible participants with hemophilia A with factor VIII (FVIII) inhibitors before it is commercially available in the United States for the indication of hemophilia A with FVIII inhibitors. Discontinuation may occur earlier if participant or physician decides to discontinue treatment or the sponsor discontinues emicizumab clinical development.
Individuals with mild hemophilia A (MHA) bleed infrequently but can in the setting of trauma which often is when participating in sports/exercise. Although both exercise and DDAVP (desmopressin) can raise Factor 8/Von Willebrand Factor (FVIII/VWF levels), it is not clear whether the pathophysiological mechanism is the same. Consequently it is not known if DDAVP and exercise would have additive effects in raising FVIII:C and VWF levels or if one would one negate the effect of the other. The aim of this 2 center (Sickkids and Columbus, Ohio), prospective, cross-over design study is to compare the impact of exercise vs. DDAVP on hemostasis in patients with MHA and also to investigate the impact of sequentially administering these interventions on their hemostatic indices.
The primary purpose of this study is to describe the outcome of Immune Tolerance Induction (ITI) treatment performed with rFVIIIFc within a timeframe of 60 weeks in patients with haemophilia A who have failed previous attempts at tolerization.
This is a multicenter, multinational, prospective, single-arm, nonrandomized, open-label study, planned in of approximately 25 male participants with congenital hemophilia A who will receive their first (primary) immune tolerance induction (ITI) treatment with alphanate. The study consists of 2 phases: - An ITI Treatment Phase in which all eligible participants will receive ITI treatment with alphanate for a period of up to 33 months. Upon confirmation of complete immune tolerization, participants will then enter a 12-month Prophylactic Phase. If, after 33 months of ITI, a participants has achieved partial immune tolerance, the participants will enter a 12-month Prophylactic Phase. - A 12-month Prophylactic Phase for all participants who meet the criteria for complete or partial success to continue on a prophylactic dosing regimen of alphanate. Due to limited enrollment, this study was early terminated.
The primary purpose of this study was to describe the time to tolerization (i.e., ITI success) with rFVIIIFc in participants within a maximum of 48 weeks (12 months) of ITI treatment.
The goal of this non-randomized, multi-center study in subjects with severe hereditary haemophilia B was to determine and compare the pharmacokinetic and safety profiles of BeneFIX in subjects having had 2 prior pharmacokinetic assessments with AlphaNine.
This trial is conducted in Europe and the United States of America. The aim of this trial is to compare the pharmacokinetics (the exposure of the trial drug in the body) of nonacog beta pegol (N9-GP) and ALPROLIX® in patients with haemophilia B.
The purpose of the study is to evaluate the safety, tolerability and time-course profile of FVIII activity after dosing with SB-525 (PF-07055480)
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.
