This study was divided into four stages: screening period, main trial period, extension period and follow-up period. In the main trial, both groups received FRSW107 prophylactic therapy. The recommended initial dose of prophylactic administration was 50 IU/kg, the dose range was 25 to 50 IU/kg, and the recommended frequency of administration was once every three days (Q3D). The dose range could be adjusted according to the patient's response. The main trial period was prophylaxis up to ≥50 exposure days (EDs) and ≥6 months. The investigator may adjust the dose according to the clinical efficacy of the subjects (the occurrence of bleeding and its clinical manifestations) and the concentration of FⅧ valley according to the following principles. If necessary, the investigator may adjust the dosing interval according to the clinical efficacy of the subject (the occurrence of bleeding and its clinical manifestations) and the concentration of FⅧ. Investigators are advised to inform sponsors or their research partners when adjusting doses and dosing intervals during prophylaxis. After participants completed prophylaxis until ≥50EDs and ≥6 months, participants' willingness and investigator evaluation were used to decide whether to enter the extended trial. All subjects entering the extended phase continued with the original prophylactic regimen until 100EDs was dosed. During the main trial period and the extended preventive treatment period, if the subjects have breakthrough bleeding events requiring treatment, hemostatic treatment of breakthrough bleeding with investigational drugs can be performed. The researchers can refer to the treatment guidance for different degrees of bleeding in Table 6-1. Taking into account the subject's prophylactic dose, severity of bleeding, site and extent of bleeding, clinical status, and previous PK results (if any), the investigator determines the appropriate dose to administer (recommended dose range: 25 to 50 IU/kg) and dosing times until the investigator assessed significant control of bleeding episodes (e.g. reduction of pain and swelling) or return to pre-bleeding activity. If the bleeding episode stops, the subject will continue with the same dose and frequency of prophylactic medication as before the bleeding episode.
This is an open- label, non- randomized, uncontrolled, dose-escalation pilot study to evaluate the safety and efficacy of KL001 injection solution in hemophilia B subjects with ≤2 IU/dl residual FIX levels.
The goal of this multicenter, two-stage, open-label study is to investigate the safety, immunogenicity, and efficacy of ANB-002 in subjects with hemophilia В. The study will have a dose-escalation design with elements of phase I/II seamless adaptive design.
This is an open- label, non- randomized, uncontrolled, dose-escalation pilot study to evaluate the safety and efficacy of KL001 injection solution in hemophilia B subjects with ≤2 IU/dl residual FIX levels.
This is a multi-center, single-arm, open-label, single-dose treatment clinical study to evaluate the safety, tolerability and efficacy of BBM-H803 injection in heavy Hemophilia A subjects. BBM-H803 is an adeno-associated viral (AAV) vector derived from recombinant DNA techniques to contain an expression cassette of the human factor VIII transgene and raises circulating levels of endogenous FVIII.
The main purposes of this study are to determine if use of emicizumab prophylaxis treatment reduces number of bleeding episodes, if it improves quality of life of individuals and if improves arthropathy in persons with hemophilia A.
Cerebral microbleeds (CMBs) are haemosiderin deposits, resulting from the leakage of erythrocytes from small cerebral vessels, which can be detected noninvasively using susceptibility-sensitive magnetic resonance imaging (MRI) techniques. CMBs are commonly observed in daily practice: their prevalence range from five percent in healthy individuals over 65 years old to 50% in patients with a history of stroke. CMBs are associated with intracerebral hemorrhage (ICH) and also cognitive impairment and dementia. The pathophysiology of CMBs is thought to primarily involve damage to brain microvasculature but the exact underlying cascade of events, including a potential role for haemostasis, has yet to be elucidated. Haemostatic defects (congenital or acquired) may contribute to an increased number and importance of CMBs. Congenital bleeding disorders such as haemophilia or von Willebrand disease (vWD), populations at high risk of ICH, are unique conditions that may give us further insights into a potential role of haemostatic defects in the pathophysiology of CMBs. CMBs might be the missing link between severe haemostatic defects, ICH risk and cognitive function. We hypothesized that severe congenital haemostatic defects could contribute to an increased prevalence and number of CMBs, with an impact on cognition in adulthood.
Recent technological innovations have enabled the creation of portable and easy-to-wear sensors with incredible potential to alter the clinical practice of rehabilitation. Using wearable sensors we have gathered preliminary data in the clinical setting measuring walking ability and function. Preliminary data shows that these wearable sensors can detect improvements in walking ability and function after a 12-week physiotherapy exercise programme in boys with haemophilia. In this proposal, we want to test the use of these wearable sensors in the patient's home to remotely monitor joint health and the effects of rehabilitation for people with haemophilia. We expect that wearable sensor technology is an efficient and promising tool to evaluate and monitor joint health and pain in persons with haemophilia. If usable in the home setting, the wearable sensors have the potential to provide immediate real-time feedback on joint health and rehabilitation goals to the patient and their haemophilia care team without the patient having to leave their home. The project will also support educational activities with researchers and patients to ensure that the use of this new type of rehabilitation will be fully integrated with their future treatment and management.
