Study of Recombinant Factor VIIa Fusion Protein (rVIIa-FP, CSL689) for On-demand Treatment of Bleeding...
Hemophilia A With InhibitorsHemophilia B With InhibitorsThe purpose of this study is to investigate the pharmacokinetics (PK), efficacy, and safety of rVIIa-FP (CSL689). The study will enroll approximately 54 male subjects, 12 to 65 years of age, with hemophilia types A or B who have developed inhibitors to FVIII or FIX. The study consists of 3 sequential parts (Parts 1, 2, 3): The purpose of Part 1 (PK part) is to evaluate the PK of a single treatment of CSL689 (low dose or high dose) and compare with the PK of a single treatment of Eptacog alfa (low dose or high dose). In Part 1, CSL689 and Eptacog alfa will be given by the doctor at the study center. The purpose of Part 2 (Dose-evaluation part) is to identify which of the 2 tested dose levels of CSL689 shows the best efficacy and safety in stopping acute bleeding events (this dose will be called the "population best dose"). The purpose of the final Part 3 (Repeated-dose part) is to confirm the efficacy and safety of the "population best dose" identified in Part 2. In Parts 2 and 3, subjects will self-administer a specified number of CSL689 infusions at home on-demand (ie, when a bleeding event occurs), will keep an electronic diary, and will visit the center at monthly intervals. This study is expected to last for up to 16 months for the subjects participating in all 3 parts, and up to 9 months for the subjects participating in Part 3 only.

Study of Ataluren (PTC124) in Hemophilia A and B
Hemophilia AHemophilia BHemophilia A (HA) and hemophilia B (HB) are inherited bleeding disorders caused by mutations in the gene for factor VIII (FVIII) and factor IX (FIX), respectively. These proteins are essential for blood clotting. The lack of FVIII/FIX can produce bleeding episodes that cause damage of the bone, muscles, joints, and tissues. A specific type of mutation, called a nonsense (premature stop codon) mutation, is the cause of the disease in approximately 10-30% of participants with hemophilia and results in severe manifestations. Ataluren (PTC124) is an orally delivered, investigational drug that acts to overcome the effects of the premature stop codon, potentially enabling the production of functional FVIII/FIX. This study is a Phase 2a trial evaluating the safety and efficacy of ataluren in participants with HA or HB due to a nonsense mutation. The main purpose of this study is to understand whether ataluren can safely increase FVIII/FIX activity levels.
Study of AAV5-hFIX in Severe or Moderately Severe Haemophilia B
Hemophilia BThis is an open-label, extension study enrolling patients who have successfully completed all assessments in Study CT-AMT-060-01 (Years 1-5). Assessment phase will begin at Visit 36 (the first clinical visit in this extension study, approximately 5.5 years after the initial dosing visit Study CT-AMT-060-01) and go to Visit 45 (10-years post-dosing in Study CT-AMT-060-01).
A Factor IX Gene Therapy Study (FIX-GT)
Hemophilia BSevere haemophilia B (HB) is a bleeding disorder where a protein made by the body to help make blood clot is either partly or completely missing. This protein is called a clotting factor; with severe haemophilia B, levels of clotting factor IX (FIX) (nine) are very low and affected individuals can suffer life threatening bleeding episodes. HB mainly affects boys and men (normally one in every 30,000 males). Current treatment for HB involves intravenous infusions of factor IX as regular treatment (Prophylaxis) or 'on demand'. On demand treatment is highly effective at stopping bleeding but cannot fully reverse long-term damage that follows after a bleed. Regular treatment can prevent bleeding, however can be invasive for patients and also expensive. This research study aims to test the safety and effectiveness of a gene therapy which produces Factor IX protein in the body. The gene will be given using an inactivated virus called "the vector" ( FLT180a), in a single infusion. The vector has been developed from a virus known as an adeno- associated virus, that has been changed so that it is unable to cause a viral infection in humans. This "inactivated" virus is further altered to carry the Factor IX gene and to make its way within liver cells where Factor IX protein is normally made. Up to three different doses cohorts of FLT180a will be tested, in up to 24 patients with severe haemophilia B. Patients will be recruited from haemophilia centres in the EU and US. Patients will be in the trial for approximately 40 weeks and will undergo procedures including physical examinations, bloods tests, ECGs and liver ultrasounds.
Long Term Follow-up (LTFU) of Subjects Who Received SB-318, SB-913, or SB-FIX
Hemophilia BMucopolysaccharidosis I1 moreLong-term follow-up of subjects who received SB-318, SB-913, or SB-FIX in a previous trial and completed at least 52 weeks post-infusion follow-up in their primary protocol.

ATHN 7: Hemophilia Natural History Study
Hemophilia A With InhibitorHaemophilia A Without Inhibitor2 moreThis is a real-world study of the safety of the treatments used for people with hemophilia. The study will follow people with hemophilia A or B from across the country for about 4 years as they receive treatment. The hemophilia treatment center (HTC) physician and participant will decide on the FDA-approved treatment to be used which may include non-factor products, bypassing agents, or clotting factor replacement products. The goal of this research is to study the use of hemophilia treatment products and their outcomes.
A Long-Term Follow-Up Study of Haemophilia B Patients Who Have Undergone Gene Therapy
Hemophilia BSevere haemophilia B (HB) is a bleeding disorder where a protein made by the body to help make blood clot is either partly or completely missing. This protein is called a clotting factor; with severe HB, levels of clotting Factor IX (nine; FIX) are very low and affected individuals can suffer life threatening bleeding episodes. HB mainly affects boys and men (approximately one in every 30,000 males). Current treatment for HB involves intravenous infusions of FIX as regular treatment (prophylaxis) or 'on demand' treatment. On demand treatment is highly effective at stopping bleeding but cannot fully reverse long-term damage that follows after a bleed. Regular treatment can prevent bleeding; however it is invasive for patients and also expensive. This clinical study aims to investigate the long-term safety and durability of FIX activity in participants who have been dosed with a new gene therapy product (FLT180a) in earlier clinical studies. Following administration, FLT180a results in production of FIX in the participants' liver cells which is then released into the blood stream. The aim is to have the participants' own body produce levels of FIX that allow for clotting to occur as normal as would be seen in a non-HB individual. This would remove the need for prophylaxis or on demand treatment following just a single administration of FLT180a. Up to 50 participants who have already been administered with FLT180a in the EU and US will take part in this study. Participants will be followed up in this trial until they have reached 15 years after being dosed. Participants will undergo procedures including physical examinations, join assessments, blood tests and liver ultrasounds. Participants will also need to complete a diary to document occurrence of bleeding episodes and record the amount of Factor IX concentrate they receive. Patient reports outcomes including measures of Quality of Life, disability and physical activity will also be collected.
