Filter by:A non-randomized, open-label, dose-escalation, phase I/II study to evaluate the safety, tolerability, kinetics and efficacy of a single intravenous infusion of ZS801 in hemophilia B subjects with endogenous FIX ≤2%.
By comparing the incidence of PONV, the dosage of postoperative antiemetic drugs, the postoperative VAS score and the utilization rate of PCIA of hemophilia A patients in the NLR≥2 and NLR<2 groups, investigators could find out the high value in the diagnosis of hemophilia A, which is helpful to guide the clinical diagnosis and treatment of hemophilia A.
A non-randomized, open-label study to evaluate the safety, kinetics and efficacy of a single intravenous infusion of ZS801 in hemophilia B subjects with endogenous FIX ≤2%.
Background. Hemophilia is characterized by the development of a progressive, degenerative, intra-articular lesion (hemophilic arthropathy). This arthropathy presents with chronic pain, limited range of motion, axial changes, and periarticular muscle atrophy. Goal. To analyze the clonic, functional and musculoskeletal differences between adult patients with hemophilic arthropathy of the knee and ankle and their healthy peers. Study design. Cases and controls study patients. 21 patients with hemophilia A and B and 21 subjects without joint damage. Variables and measuring instruments: pressure pain threshold (pressure algometer); joint status (Hemophilia Joint Health Score scale); and strength (dynamometry) and muscle activation (surface electromyography). Expected results. Observe the differences between patients with knee and ankle arthropathy and their healthy peers in muscle strength and activation.
A non-randomized, open-label, dose-escalation study to evaluate the safety, tolerability, kinetics and efficacy of a single intravenous infusion of ZS802 in hemophilia A subjects with endogenous FVIII ≤2%.
This is a single-arm, open-label, clinical study to evaluate the safety, tolerability of BBM 002 injection in Hemophilia A subjects with residual factor VIII (FVIII) levels ≤2 International unit per deciliter (IU/dl) . BBM 002 injection is an adeno-associated virus (AAV) vector derived from recombinant DNA techniques to contain an expression cassette of the human factor VIII (hFVIII) transgene and raises circulating levels of endogenous FVIII.
This is a prospective, open, multicenter, observational lead-in study，to collect prospective efficacy and safety data of current replacement therapy in adult hemophilia B patients.
A multicenter, open, non-randomized, phase I/II, two-phase clinical study. The dose exploration phase was phase I, and the dose extension phase was phase II.
We have developed a questionnaire to elucidate the dosing, frequency and indication for the use of emicizumab in patients with Hemophilia A (mild, moderate or severe) ages 0-3 years. We are also collecting data on any pre-, peri and post surgical practices while on emicizumab. More importantly, we are asking if pediatricians are planning to introduce factor 8 to children who are already on emicizumab for primary prophylaxis as well as how and when they are planning to do so. We hope that this data will help inform understanding of current use of emicizumab in infants and young children as a form of primary prophylaxis, especially when venous access has historically been a limiting factor.
Hemophilia (A and B) are X-linked hereditary bleeding disorders whose severity depends on the level of coagulation factor (FVIII or FIX respectively). Bleeding is mainly from joints (hemarthrosis) and muscles (hematoma). Nowadays, treatment is based on preventive or curative intravenous infusion of coagulation factor concentrates. Despite these treatments, there is joint deterioration that can be responsible for hemophilic arthropathy and chronic pain. This pain may be related to excess nociception during acute bleeding, but it may also be neuropathic. There are only a few studies that have looked at pain in hemophilia, but it is accepted that the vast majority of patients (especially those with severe forms) suffer from chronic pain. Because patients have become accustomed to this pain and physicians are still not very aware of how to assess it, this pain is not treated effectively. In order to better manage pain in hemophilia, it is therefore necessary to characterize their pain and to know the nociceptive or neuropathic component. The aim of our study is therefore to study the prevalence, the nociceptive or neuropathic profile, the chronic aspect of pain and the main locations of pain in hemophilia. In addition to raising the awareness of physicians in the centers about pain management using specific questionnaires, this survey will help to better define chronic pain in hemophilia of all severities.
