Filter by:Participants in this study have a genetic mutation, specifically in the coagulation (blood clotting) Factor 9 gene that causes severe or moderately severe hemophilia B. This study is researching an experimental gene insertion therapy (the adding of a gene into your DNA) called REGV131-LNP1265, also called the "study drug". Gene insertion therapy aims to teach the body how to produce clotting factor long-term, without the need for factor replacement therapy. The main aim of this study is to find a safe and well-tolerated dose of the study drug by checking the side effects that may happen from taking it. The study is looking at several other research questions including: - How much study drug is in the blood at different times - Whether the body makes antibodies against parts of the study drug, which could make the drug less effective or could lead to side effects. Antibodies are proteins produced by the body's immune system in response to a foreign substance - Whether the body makes antibodies against the clotting factor replacement therapy - How quality of life is affected by hemophilia B and if it changes after taking study drug - How joint health is affected by hemophilia B and if it changes after taking study drug - How often visits are required for the emergency room, urgent care center, physician's office, hospital, telephone or online are required as a result of bleeding events, and if the frequency changes after taking study drug - How often factor replacement therapy is needed, both on a regular basis for prevention of bleeding, and as needed to treat bleeding events (and it if changes after taking study drug) - Whether there is a difference in 2 different methods for measuring Factor 9 activity in the blood
This observational study consists of two parts. In part one, case scenario focus groups with hemophilia A patients and healthcare providers (HCPs) will be held. This parts aims to identify potential use scenarios of a point of care (POC) in vitro medical for patients with hemophilia A. The main questions it aims to answer are: - How is coagulation lab testing for patients with hemophilia A currently organized? - What is the interest and what are desired alternatives of a POC in-vitro diagnostic medical device for patients with hemophilia A? Part two of the study consists of a use scenario study in which patients with hemophilia A and HCPs will evaluate two types of non-functional mock-ups of a POC in vitro medical device. The main goal of this part is to evaluate the usability of the current prototypes of the POC device.
The goal of this observational study is to assess if the version A of the HemA EnzySystem, a novel portable coagulation testing platform, can be used in patients with hemophilia A treated with Factor VIII Bypassing Agent (FEIBA). The main question[s] it aims to answer are: - Can the version A of the HemA EnzySystem can record thrombin generation within a time frame of 60 min in fresh whole blood samples of patients with hemophilia A treated with FEIBA? - Are the TGA results of the version A of the HemA EnzySystem in agreement with the TGA results obtained with conventional methods in fresh non frozen plasma? Participants are asked to fill in a questionnaire regarding their general health and hemophilia treatment. Subsequently, blood will be drawn from the patients before, and at 30, 120, and 240 minutes after FEIBA administration. Whole blood is immediately tested using the Version A HemA EnzySystem, and plasma is generated for testing with the Ceveron s100 (Technoclone). Leftover samples are frozen for later additional coagulation testing.
The aim of this study is to evaluate the prevalence of synovitis in adult patients with haemophilia A.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamic (PD) of SR604 in healthy participants (Part A) and to evaluate the safety, tolerability, PK, PD, and efficacy of SR604 in participants with severe Hemophilia A or Hemophilia B, with or without inhibitors (Part B).
This randomised controlled study was conducted to investigate the comprehensive physiotherapy combined with home exercises on individuals with hemophilic arthropathy in the lower extremity. There are two groups in the study: home exercises and comprehensive physiotherapy combined with home exercises. Is physiotherapy combined with home exercises superior to home exercises on joint health, bleeding frequency, reaction time, dynamic balance, muscle strength? The aim of this study is to increase the compliance of hemophilic individuals to physiotherapy and adapt home exercises to their lives with weekly sessions.
The goal of this multicentre, prospective, open-label, cross-over clinical study is to determine whether individualized PK-guided dosing of emicizumab is non-inferior to conventional dosing of emicizumab in the prevention of bleeding in congenital haemophilia A patients.
The purpose of this study is to show that KN057 can prevent bleeds in patients with haemophilia A or B with inhibitors and is safe to use. Successfully screened participants will be randomly assigned to KN057 Prophylaxis (Arm 1) versus No Prophylaxis (Arm 2) at a ratio of 2:1. Participants in KN057 Prophylaxis will receive KN057 prophylaxis for 52 weeks upon enrollment. Participants in No Prophylaxis will first receive on-demand treatment for 26 weeks, then switch to KN057 prophylaxis for 26 weeks.The trial period is 59 weeks, including a 3-week screening period, a 26-week main trial, a 26-week extension period, and a 4-week follow-up period after the last administration.
This study is a single arm, open, multicenter clinical trial in which the previous treated severe hemophilia A patients receive recombinant human coagulation factor VIII for injection to evaluate the efficacy and safety of on-demand treatment in the event of new bleeding events. If evaluable surgical cases occur, the overall efficacy and safety of recombinant human coagulation factor VIII for injection as a replacement therapy for severe hemophilia A PTPs during the perioperative period will be evaluated.
The purpose of this study is to evaluate the efficacy of SPK-8011 in preventing bleed episodes compared with FVIII prophylaxis in participants with hemophilia A without FVIII inhibitors on routine FVIII prophylaxis.
