Filter by:This study will assess the safety and efficacy of multiple-dose of STSP-0601 for the treatment of bleeding episodes in hemophilia A or B patients with inhibitor.
Background. The main physical sequela of patients with hemophilia is the development of a progressive, degenerative intra-articular lesion, known as hemophilic arthropathy). This sequela is manifested by chronic pain, limited range of motion, axial abnormalities, and periarticular muscle atrophy. Objective. To assess the safety and effectiveness of an intervention through blood flow restriction, regarding the frequency of bleeding and the improvement in muscle activation and strength, range of motion, stability, joint pain, joint status and the perception of quality of life in patients with hemophilic ankle arthropathy. Study design. Randomized, multicenter, single-blind clinical study. Method. 32 patients with hemophilia A and B will be recruited in this study. Patients will be recruited in 4 regions of Spain. The dependent variables will be: bleeding frequency (self-registration), pain (measured with the visual analog scale and pressure algometer), quality of life (SF-36 scale), joint status (Hemophilia Joint Health Score scale), strength (dynamometer) and muscle activation (surface electromyograph), range of motion (goniometer) and stability (The Single Leg Stance Test). Three evaluations will be carried out: pre-treatment, post-treatment and after a follow-up period of 4 weeks. Expected results. Observe the safety of blood flow restriction in hemophilia patients. To analyze the efficacy of blood flow restriction in improving muscle strength and activation, range of motion, chronic pain, stabilit, and the perception of quality of life in patients with hemophilic ankle arthropathy.
This is an open-label, multicenter Phase 1Ib/2II clinical trial of SS109 in adult hemophilia patients (≥ 18 years) with FVIII or FIX inhibitors to evaluate the PK/PD profile of SS109 and NovoSeven® after a single dose in adult hemophilia patients with FVIII or FIX inhibitors, to assess the preliminary efficacy and PK profile of SS109 during on-demand treatment, and to observe the safety and immunogenicity of SS109 throughout the study. The trial consists of three periods: screening period, PK study period, and on-demand treatment period. In the PK study period, subjects are divided into 2 cohorts (90 μg/kg and 270 μg/kg), which are sequentially conducted. Cohort 1 (90 μg/kg) enrollment is performed firstly, and Cohort 2 (270 μg/kg) enrollment is performed after Cohort 1 enrollment is completed. Subjects enter the PK study period as non-randomized. All screened eligible subjects will receive a single dose of comparator NovoSeven® in the absence of significant active hemorrhage, followed by PK/PD sample collection; then receive a single dose of the same dose of investigational drug SS109, followed by PK/PD sample collection. Specific times for PK/PD sample collection are listed in the schedule for biological sample collection. After completion of the PK study period, subjects will enter a 90-day on-demand treatment period and will be randomized into 3 groups (Group 1: 90 µg/kg, Group 2: 180 µg/kg, and Group 3: 270 µg/kg) at a ratio of 1:1:1. During on-demand treatment, subjects are treated on-demand with SS109 at the time of a new hemorrhage event and their efficacy is observed. The investigator will judge the severity of subject's hemorrhage according to the type, location, clinical symptoms and signs of the subject's hemorrhage. Appropriate hemostatic treatment regimens and whether or not to perform the first SS109 on-demand treatment for the hemorrhage event at home may be developed by the investigator based on the subject's on-demand treatment group, according to the severity of hemorrhage and the recommended dosing frequency of SS109 (see Dosage/Regimen), and the dosing interval may be adjusted in conjunction with the subject's response to treatment. If the subject's last hemostatic treatment is administered within one week before the D96 visit point during the on-demand treatment period, the subject is required to continue follow-up observation for one week after the last dose before completing the end of study visit. PK/PD samples will be collected as appropriate during on-demand treatment, as specified in the schedule for biological sample collection.Observe subject safety throughout the study.
The goal of this clinical trial is to determine the clinical efficacy and toxic effects of sodium valproate, sirolimus and calcitriol in the treatment of severe haemophilia in participants with severe haemophilia . The main questions it aims to answer are the possibility of adding a combination regimen to primary treatment for severe haemophilia . Patients will receive oral sodium valproate extended-release tablets 0.5g/day, sirolimus tablets 1mg/day and osteopontin capsules 0.25μg/day.
Retrospective Experience Assessing the Real-World Utilization and Effectiveness of SEVENFACT® [coagulation factor VIIa (recombinant)-jncw] in the USA. The current study will provide a unique opportunity to describe the profile of the early patients selected for treatment with SEVENFACT® and to assess the real-world utilization (effectiveness, safety, tolerability, and modalities of treatment) of SEVENFACT®.
"Being able to participate in games and activities with their friends" is one of the things that matters most to boys with haemophilia. At present, there is a lack of robust evidence to determine whether muscle strengthening exercise can improve or negatively affect outcomes for young children with haemophilia. With the help of boys with haemophilia, their parents and physiotherapists the investigators have developed an exercise programme designed to increase muscle strength. Using this intervention the investigators will undertake a single-blinded, two-arm pragmatic randomised controlled trial (RCT) of a 12-week intervention verses usual care of boys with haemophilia aged 6-12 years of age.
This is an interventional, prospective, international, multicenter, single-arm, Phase 3, and sequential efficacy and safety study in adolescents and adults with congenital hemophilia A or B with inhibitors to factor VIII (FVIII) or factor IX (FIX) undergoing elective major surgical procedures.
This is a multicenter, multinational, open-label, one-way cross-over, Phase 3, single-arm study for treatment of hemophilia. The purpose of this study is to measure the frequency of treated bleeding episodes with fitusiran in male adult and adolescent (≥12 years old) participants with hemophilia A or B, with or without inhibitory antibodies to factor VIII or IX who have switched from their prior standard of care treatment. The total study duration will be up to approximately 50 months (200 weeks, 1 study month is equivalent to 4 weeks) and will include: - A screening period up to approximately 60 days, - A standard of care (SOC) period of approximately 6 study months (24 weeks), - A fitusiran treatment period of approximately 36 study months (144 weeks), - An antithrombin (AT) follow-up period of approximately 6 study months (24 weeks) but may be shorter or longer depending on individual participants AT recovery. The frequency for telephone visits will be approximately every 2 weeks. For site visits the frequency will be approximately every 8 weeks during the SOC period and approximately every 4 weeks during the fitusiran treatment period. If applicable and if allowed by local regulation, home and/or remote visits may be conducted during the study
This is a longitudinal, prospective study, which will include 30 subjects with hereditary coagulopathies, with arthropathy, chronic synovitis resulting from hemarthrosis of the elbows, knees and/or ankles followed up at the Centro de Hemofilia HCFMUSP, after approval by the ethics and research committee. They will undergo imaging tests (X-rays and Magnetic Resonance of knee, elbow, or ankle), physical, pain, quality of life and functional assessments (Hemophilia Joint Health Score, Functional Independence Score in Hemophilia, Perimeter, Test Timed up and Go, 30 second sit and stand test, Haemophilia - Adult - Quality of Life questionnaire (HAEM-A-QoL), Knee Injury and Osteoarthritis Outcome Score, EQ-5D, numerical rating scale for pain and embolization procedure (superselective embolization of target arteries with spherical microparticles Embosphere 100-300 micrometers (Biosphere Medical, Roissy, France), until partial vascular stasis and decharacterization of pathological synovial enhancement. These evaluations will be performed at baseline, 1, 3, 6, 12, 24, 36, 48 and 60 months after the procedure.
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.
