Active clinical trials for "Hemophilia A"

Studies have shown, in haemophilia patients, the effectiveness of Anti TFPI antibody (aTFPIAb) to prevent joint and muscular bleeding (tissues poor in Tissue Factor (TF)). However, cases of cerebral thrombosis (tissues rich in TF) have been observed in some patients treated with this antibody. Because an inter-individual variation in thrombin generation correction by aTFPIAb, an aTFPIAb concentration effective at low TF concentration could be at the same time thrombogenic at high TF concentration.

A multicenter, open, non-randomized, phase I/II, two-phase clinical study. The dose exploration phase was phase I, and the dose extension phase was phase II.

The purpose of this study is to determine the safety of giving a normal factor IX gene to treat individuals who have an abnormal or no factor IX gene. Recruitment will be limited to adults (≥ 18 years) with a confirmed diagnosis of hemophilia B (HB), resulting from a missense mutation in the coagulation factor IX (FIX) gene or a nonsense mutation that has not been associated with an inhibitor. Only subjects who have no evidence of active hepatitis or anti-hFIX antibodies, and who have been treated/exposed to Factor IX concentrates for at least ten years and have had an average of 3 bleeding episodes per year requiring FIX administration will be enrolled. Patients will be recruited within the United States for treatment at St. Jude Children's Research Hospital, and patients will be recruited in England and other countries for treatment in London by our British collaborators.

To establish baseline prospective efficacy data of current FIX prophylaxis replacement therapy in the usual care setting of hemophilia B subjects, who are negative for nAb to AAV-Spark100, prior to the Phase 3 gene therapy study. To establish baseline prospective efficacy data of current FVIII prophylaxis replacement therapy in the usual care setting of hemophilia A subjects, who are negative for nAb to AAV6, prior to the Phase 3 gene therapy study. The enrollment for hemophilia A participants is completed. At this time participants are only being enrolled for hemophilia B cohort.

The primary purpose of this study is to assess the long-term safety in male adults with hemophilia B who were treated with CSL222 in studies CSL222_2001 (NCT03489291) or CSL222_3001 (NCT03569891).

This is a study on Italian patients with haemophilia A in prophylaxis treatment with Turoctocog alfa under routine clinical conditions. The purpose of the study is to investigate the therapeutic scheme in a population of patients treated with Turoctocog alfa and to investigate the participation in recreational activities, the level of physical activity, and quality of life. Participants will get NovoEight® (Turoctocog alfa) as prescribed to them by the study doctor. The study will last for about 12 months. Participants will be requested to fill in the Questionnaires investigating the participation in recreational activities, the level of physical activity, and quality of life.

This non-interventional study concerns a safety data collection based on adverse event data from a third-party registry (European Haemophilia Safety Surveillance System, EUHASS) that includes information about adverse events from patients with haemophilia A treated with turoctocog alfa pegol. There is no extra burden to the patients by participating in this registry-based data collection.

The purpose of this study is to assess the safety and effectiveness of Esperoct® for long-term routine use in patients with Haemophilia A. Participants will get Esperoct® as prescribed by their doctor. The study will last for about 2 years for each participant.

This study will collect information on side effects and how well Esperoct® (turoctocog alfa pegol (N8-GP)) works during long-term treatment (prophylaxis) in males with haemophilia A. Participants in this study will get the same treatment as they would normally get, if they were not participating in the study. All visits at the clinic are done in the same way as participants are used to, when visiting their doctor. During visits at the clinic participants might be asked for some relevant tests if considered useful by the study doctor. During the visits the study doctor might ask if participants had any side effects since the last study visit. Participants will be asked to note down in their own diary the number of bleeds and how these were treated, as well as their regular prophylaxis. Participation in the study will last for about 5-7 years, depending on when participants 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.

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®.
