Filter by: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.
This observational, post-authorization, long-term follow-up study aims to investigate the short and long-term effectiveness and safety of HEMGENIX in patients with hemophilia B. The study will also include a cohort of patients with hemophilia B treated with FIX prophylaxis to enable interpretation of relevant efficacy and safety findings of HEMGENIX.
The purpose of this study is to assess the risk of bleeding due to failure of expected pharmacological action of CSL222 in adults with severe or moderately severe hemophilia B with detectable pretreatment AAV5 Nabs.
Study WP44714 is a Phase I/II, open-label, non-randomized, global, multicenter, multiple-ascending dose (MAD) study in adult and adolescent male participants with severe or moderate hemophilia A with or without factor VIII (FVIII) inhibitors. The aim is to investigate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and efficacy of multiple ascending doses of NXT007.
Study Objectives* 1. Provide a systematic evaluation of the treatment outcomes in patients with hemophilia A 2. Emphasize the importance and clinical benefits of rFVIII-Fc in joint and bone health. 3. Compare the clinical outcomes from 1 year before and after switching to EHL. 4. Exploratory: Identify biomarkers that could provide more useful and convenient evaluations of joint and bone health. (Time-saving and easy to monitor)
Recombinant factor VIII for the prevention of bleeding in patients with severe haemophilia A undergoing major surgery while receiving emicizumab prophylaxis
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.
This is a prospective, observational, multi-center longitudinal cohort study to describe the real-world effectiveness, safety and treatment usage of efanesoctocog alfa in patients with hemophilia A treated per standard of care in the US and Japan. Patients will be enrolled in the study after the introduction of efanesoctocog alfa in the hemophilia treatment landscape in each study country. Decision to initiate treatment with commercially available efanesoctocog alfa will be made by the treating physician independently from the decision to include patients in the study. No study medication is provided. The data related to efanesoctocog alfa effectiveness, safety and usage will be collected prospectively during routine visits (expected annual/semi-annual visits) for up to 5 years following enrollment /treatment initiation.
"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.
To evaluate the time of response, sustained remission rate, and relapse rate of CD38 monoclonal antibody (Daratumumab) combined with SCT800 (rFVIII) in the treatment of hemophilia A adolescents and adults with high titer inhibitors.
