Filter by:This study is a Phase I trial using an advanced lentiviral vector to deliver a functional gene for human clotting factor IX into patients with hemophilia B, to evaluate the safety and efficacy of infusion of lentiviral gene modified autologous stem cells in patients.
It appears that the mutation p.Ile112Thr in the factor IX gene confers a discrepancy between mild factor IX level and severe bleeding phenotype. Databases and litterature analysis are poor on this matter. The goal of this study is to compile bleeding phenotype in patients with this specific mutation to prove the clinico-biological discordance in order to improve patient care and follow-up.
Treatment with PF-06741086 is anticipated to demonstrate a clinically relevant advantage and/or a major contribution to patient care in comparison to current methods of treatment for hemophilia A or B because it works differently than factor replacement products and will work in the presence of inhibitors. The potential for once weekly (QW) subcutaneous (SC) administration provides for treatment options in the absence of reliable vascular access, increased convenience and may enable better compliance. Combined, these qualities should result in a reduction of bleeding episodes.
Alprolix (rFIXFc) is a recombinant extended half-life coagulation factor product. The purpose of this non-interventional study is to describe the real-world usage and effectiveness of Alprolix in the on-demand and prophylactic treatment of haemophilia B.
The participants are invited to take part in this study because they have Haemophilia B. The purpose of this study is to assess the safety and effectiveness of Refixia® about long-term routine use in patients with Haemophilia B. The participants will get Refixia® as prescribed to them by their study doctor. The study will last up to Sep 2025 for the participant. The participants may be asked to fill in the quality of life questionnaires (if they are above age of 15). The blood samples taken from the participants as part of routine clinical practice will also be used to investigate the safety for the long-term use of Refixia®.
This study will evaluate the efficacy and safety of PF-06838435 (a gene therapy drug) in adult male participants with moderately severe to severe hemophilia B (participants that have a Factor IX circulating activity of 2% or less). The gene therapy is designed to introduce genetic material into cells to compensate for missing or non-functioning Factor IX. Eligible study participants will have completed a minimum 6 months of routine Factor IX prophylaxis therapy during the lead in study (C0371004). Participants will be dosed once (intravenously) and will be evaluated over the course of 6 years. The main objective of the study will evaluate the annualized bleeding rate [ABR] for participants treated with gene therapy versus standard of care (SOC) therapy (FIX prophylaxis replacement regimen).
Phase 3/4, single arm, open-label study to evaluate PK, safety, and efficacy of APVO101 prophylaxis in severe or moderately severe hemophilia B subjects < 12 years of age.
This is a multi-center cohort study of approximately 250 previously untreated patients (PUPs) with congenital moderate to severe hemophilia A or B in a network of up to 50 US Hemophilia Treatment Centers (HTCs). Participants will be followed as they receive their first 50 exposure days (ED) to clotting factor replacement product, both prospectively and retrospectively. The data collected on evolving treatment practices will define the incidence and risk factors for inhibitor development during the high risk period of first 50 ED and improve the outcomes of this vulnerable population.
This study will collect information on side effects and how well Refixia/REBINYN works during long-term treatment (prophylaxis) in males with haemophilia B. While taking part in this study, participants will receive the same treatment as given to them by their study doctor. All visits at the clinic are done in the same way as the participants are used to. During visits at the clinic, participants might be asked for some relevant tests if considered useful by their study doctor. During the visits, the participants study doctor might ask if the participants had any side effects since their last study visit. The participants will be asked to note down the number of bleeds and the treatment of their bleeds as well as their regular prophylaxis. During the visits to the clinic, the participants will be asked to answer some questionnaires about their quality of life and their ability to be physically active. The participant's participation in the study will last for 4-9 years, depending on when they join the study. Participants are free to leave the study at any time and for any reason. This will not affect their current and future medical care.
This study will collect data on bleeds and data related to quality of life in people with severe congenital (a disease existing from birth) haemophilia A and B, with or without inhibitors. The aim for the study is to look at the number of bleeds when on usual treatment for haemophilia. Participants will be asked to keep an electronic diary to track the number of bleeds and the treatment of their bleeds. Participants will be asked to wear an activity tracker on their wrist to capture their level of activity every day for up to 12 weeks. While taking part in this study, participants will keep getting their usual treatment as given to them by their doctor. All study visits at the clinic are done in the same way as the participants are used to. In the time between the participants' visits to the clinic, the study staff at the clinic may call or email the participant. The study will last for about 2½ years.
