Filter by:The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called marstacimab) for the potential treatment of hemophilia in pediatric patients. This study will enroll pediatric participants from ages 1 to 17 years in a sequential manner. The study will open enrollment to adolescent participants aged 12 to 17 years first. Then children aged 6 to 11 years will be permitted to enroll. Lastly, children aged 1 to 5 years will be permitted to enroll. This study will enroll participants who: - have severe Hemophilia A or moderately severe to severe Hemophilia B (with or without inhibitors) - have accurate historical records documenting all factor VIII, factor IX, or bypass agent infusions and hemophilia bleed events for at least 1 year prior to entering the study - if a non-inhibitor patient, must be on a stable routine prophylaxis regimen with factor VIII or factor IX replacement products for at least 12 months prior to study entry - if an inhibitor patient, must be on an on-demand bypass treatment regimen during the 12 months prior to study entry All participants in this study will receive marstacimab to use prophylactically. Marstacimab will be given once a week as a subcutaneous (under the skin) shot. The first dose of marstacimab will be given at the study site by the study site staff. During the 12-month treatment period, weekly doses of marstacimab can be given at home, or if preferred, the doses may be given by the study site staff. To help us determine if the study medicine is safe and effective, we will compare participant experiences when they are taking the study medicine to a historical period when they were not. Researchers want to see if the study medicine works to prevent the bleeding episodes commonly experienced by patients with Hemophilia. Participants will be in this study for about 14 months (approximately 1 month in a Screening period, 12 months receiving treatment, and 1 month in a follow-up period) during which they will visit the study site at least 10 times. If preferred, and if local regulations allow it, 2 of the study visits can be completed at the participant's home instead of at the study site. There will also be 6 scheduled telephone calls approximately every 2 months.
Joint pain has been reported as a major problem in people with haemophilia (PwH). Therefore, haemophilia in adults seems clinically more related to a musculoskeletal disorder than a bleeding disorder, with many patients reporting a pain intensity exceeding 6/10 on a visual analogue scale. However, although the complexity of joint pain has been studied in chronic joint pain conditions such as low back pain, osteoarthritis or rheumatoid arthritis, until present only very limited research has been done on joint pain within PwH. Therefore, exploring the underlying mechanisms and the functional implications of this intense joint pain is urgently needed. As such, the main aim of the current prospective observational study is to gain more insights in joint pain in PwH enabling us to move towards adequate pain management in PwH.
The primary objective of this study is to obtain prospective baseline documentation of annualized bleeding rates (ABRs) and treatment under standard-of-care (SOC) therapy among participants with hemophilia A or B. Participants in the study may be eligible to enroll in future planned interventional studies to be conducted by Sponsor.
A study to learn about the long-term safety and efficacy of giroctocogene fitelparvovec or fidanacogene elaparvovec in patients with hemophilia A or hemophilia B respectively, who have received treatment through prior participation in a Pfizer-sponsored clinical trial. Data collection and participant visits will be based on standard of care.
This study is focused on males who have Hemophilia B and who need regular preventive treatment with factor IX protein (FIX) replacement therapy to prevent and also to control their bleeding events. The aim of the study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental treatment being tested in this study. The study is informational, and part of a larger program to understand and treat Hemophilia B with a potential experimental new therapy in the future. There is no obligation to agree to taking part in this future study. The study is looking to answer several other research questions to help understand each participant's individual disease characteristics, including: - How often to use FIX replacement therapy, both on a regular basis (prophylaxis) and as needed to treat bleeding events - Measurement of FIX activity (factor IX is a clotting factor) by different laboratories using different types of tests in Hemophilia B participants - Possible complications from the FIX replacement therapy the patient receives (usual standard of care will continue to be used) - How quality of life is affected by Hemophilia B - How joint health is affected by Hemophilia B - How often the participant visits the emergency room, urgent care center, physician's office, hospital, or has a telemedicine visit as a result of bleeding events - Whether the body makes antibodies (a protein produced by the body's immune system) against the FIX replacement therapy you receive, which could make the drug less effective or could lead to side effects
Human coagulation factor VII is a vitamin K-dependent serine endogenous protease, and its activated form plays an important role in the coagulation process. Recombinant human activated coagulation factor VII is an activated state coagulation factor VII obtained by recombinant means.
This is a prospective, open, multicenter, observational lead-in study，to collect prospective efficacy and safety data of current replacement therapy in adult hemophilia B patients.
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 aim of this study is to investigate the Turkish validity and reliability of the Canadian Haemophilia Outcomes-Kids' Life Assessment Tool version2.0. Patients aged 4-18 years with hemophilia a or b will be included in the study. The study was planned as a multicenter and it is aimed to reach 100 patients. The process included four steps: a linguistic adaptation, cognitive debriefing interviews with children and their parents, a validity assessment with the Pediatric Quality of Life Inventory (PedsQL) as a comparator, and a test retest reliability assessment.
The study investigates how well the medicine called nonacog beta pegol (N9-GP) works in Chinese people with haemophilia B. Participants will be treated with N9-GP. This is a medicine that doctors can already prescribe in other countries. The medicine will be injected into a vein (intravenous injection). At the visits to the clinic, the medicine will be injected by the study doctor. When treating themselves at home, participants inject the medicine using a needle and vial set. The study will last for about 12-16 months. The participants will have between 9 and 19 visits to the clinic and possibly also some phone calls with the study doctor. At all visits to the clinic, the participants will have blood samples taken.
