Filter by:The goal of this observational study is to assess if the version A of the HemA EnzySystem, a novel portable coagulation testing platform, can be used in patients with hemophilia A treated with Factor VIII Bypassing Agent (FEIBA). The main question[s] it aims to answer are: - Can the version A of the HemA EnzySystem can record thrombin generation within a time frame of 60 min in fresh whole blood samples of patients with hemophilia A treated with FEIBA? - Are the TGA results of the version A of the HemA EnzySystem in agreement with the TGA results obtained with conventional methods in fresh non frozen plasma? Participants are asked to fill in a questionnaire regarding their general health and hemophilia treatment. Subsequently, blood will be drawn from the patients before, and at 30, 120, and 240 minutes after FEIBA administration. Whole blood is immediately tested using the Version A HemA EnzySystem, and plasma is generated for testing with the Ceveron s100 (Technoclone). Leftover samples are frozen for later additional coagulation testing.
The goal of this multicentre, prospective, open-label, cross-over clinical study is to determine whether individualized PK-guided dosing of emicizumab is non-inferior to conventional dosing of emicizumab in the prevention of bleeding in congenital haemophilia A patients.
The purpose of this study is to show that KN057 can prevent bleeds in patients with haemophilia A or B with inhibitors and is safe to use. Successfully screened participants will be randomly assigned to KN057 Prophylaxis (Arm 1) versus No Prophylaxis (Arm 2) at a ratio of 2:1. Participants in KN057 Prophylaxis will receive KN057 prophylaxis for 52 weeks upon enrollment. Participants in No Prophylaxis will first receive on-demand treatment for 26 weeks, then switch to KN057 prophylaxis for 26 weeks.The trial period is 59 weeks, including a 3-week screening period, a 26-week main trial, a 26-week extension period, and a 4-week follow-up period after the last administration.
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.
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.
This phase I study aims to evaluate the safety, PK/PD and immunogenicity of SS109 in hemophilia A or and B with inhibitors. Twenty -seven patients are enrolled in study, and divided into five dose cohorts, from 30μg/kg to 360μg/kg. Dose 1 cohort enrolls three patients, each other dose cohorts enroll six patients. All patients included in the study will continue to be followed up until 28 days after SS109 administration.
To evaluate Safety and efficacy and pharmacokinetics, FVIII Inhibitor titers of Hemlibra subcutaneous injection (SC inj.) in Korean Hemophilia A patients with/without FVIII Inhibitors.
Randomized, double-blind, single-dose, 5 ways crossover, exploratory clinical trial evaluating four different doses of AryoSeven (eptacog alfa, activated) and NovoSeven on selected pharmacodynamic parameters in patients with hemophilia with inhibitors.
Aim of this trial is to assess the pharmacokinetics and pharmacodynamics (PK/PD) of recombinant human coagulation factor VIIa for injection (FⅦa) in patients with hemophilia.
This study aims to examine the real-life experience and impact of using emicizumab in a cohort of patients with haemophilia and inhibitors, who were prescribed emicizumab as part of the early access to medicine schema (EAMS),those who have been in clinical trials and those now receiving emicizumab as part of routine haemophilia care. The Investigators also intend to capture the impact of emicizumab use on the lives of close family members (parents/carers/children/partners/siblings). Each participant and his family members will be deemed a study 'dyad'. This is a prospective, observational cohort qualitative research study to be conducted among patients using emicizumab in routine clinical practice. The study is designed to allow English-speaking patients and their families to tell their own life stories through narrative accounts. The narratives represent a true sharing of experiences and therefore offers insight into how these patients and families cope with haemophilia.
