Filter by: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.
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.
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 Phase I/II clinical study will evaluate the safety and efficacy of valoctocogene roxaparvovec in patients with severe haemophilia A and inhibitors to FVIII. Part A of the study will involve subjects who have active inhibitors to FVIII, and Part B involving subjects with a prior history of inhibitors.
Phase IV multi-center, US-centric, open-label, safety study enrolling participants with Hemophilia A or B with inhibitors12 years of age and older, who are either on long term prophylactic treatment (e.g., emicizumab) at risk of experiencing a breakthrough bleeding event (BE), or who are not on prophylactic treatment who may need to control a BE.
The purpose of this study is to demonstrate that PEGylated liposomes (PEGLip) can shield FVIII from the immune system and inhibitors, and therefore provide a prophylactic FVIII replacement therapy for patients with inhibitors to FVIII.
The study start on January 18, 2017. The Severe(FⅧ<1%) and moderate hemophilia A (FⅧ1%～5%)children with high titer inhibitor(historical peak inhibitor titer≥5BU ) combining with poor ITI risk(s) were enrolled. The low-dose ITI was alone or combined with immunosuppression.
