Filter by:The main objectives of this study are to evaluate safety and chronic effects of a low-load resistance exercise intervention (elbow flexions and extensions, and knee extensions) with blood flow restriction in people with hemophilia on quality of life, pain, and on physical and neuromuscular function.
Hemophilia is associated with osteoporosis and increased prevalence of low bone mineral density (BMD). Many clinical risk factors have been reported, such as hemophilic arthropathy, reduced physical activity, decreased sun exposure, hepatitis C virus infections, vitamin D deficiency, and low body mass index (BMI). There is no data on the prevalence of vitamin D deficiency and low BMD in hemophilia patients in Taiwan or Asia. To the best of our knowledge, no previous studies have reported the prevalence of sarcopenia and correlation with osteoporosis in hemophilia adult patients. The purpose of this study will evaluate the prevalence of vitamin D deficiency, low BMD, sarcopenia and body composition in a cohort of patients with hemophilia in Taiwan.
The purpose of this study is to assess the safety and tolerability, pharmacokinetics and pharmacodynamics of subcutaneous MG1113 in the multiple ascending dose study in patients with severe hemophilia.
This study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of multiple subcutaneous doses of KN057 in subjects with hemophilia A or B, with or without inhibitors to Factor VIII (FVIII) or Factor IX (FIX). 24 adult participants 18 to 70 years of age with moderately severe to severe hemophilia A or hemophilia B (defined as FVIII or FIX activity ≤2%, respectively) with or without inhibitors (including 18 HA/HB patients without inhibitors and 6 HA/HB patients with inhibitors) are expected to be enrolled in this study during which they will receive prophylaxis treatment (defined as treatment by SC injection once weekly of KN057).
This study will assess the pharmacokinetics and pharmacodynamics of STSP-0601 at five dose levels. The results will help identify the most optimal doses to treat bleedings in hemophilia patients with inhibitors.
Background Hematological diseases are disorders of the blood and hematopoietic organs. The current hematological cohorts are mostly based on single-center or multi-center cases, or cohorts with limited sample size in China. There is a lack of comprehensive and large-scale prospective cohort studies in hematology. The purpose of this study is to analyze the incidence and risk factors of major blood diseases, the treatment methods, prognosis and medical expenses of these patients in China. Method The study will include patients diagnosed with acute myeloid leukemia, multiple myeloma, hemophilia, aplastic anemia, leukemia, myelodysplastic syndrome, lymphoma, bleeding disorders or received bone marrow transplantation in the investigating hospitals from January 1, 2020, and collect basic information, diagnostic and treatment information, as well as medical expense information from medical records. In its current form, the NICHE registry incorporates historical data (collected from 2000) and is systematically collecting prospective data in two phases with broadening reach. The study will use questionnaire to measure the exposure of patients, and prospectively follow-up to collect the prognosis information.
In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well-controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.(7)
Haemophilia is a rare bleeding disorder, characterized by factor VIII (HA) or factor IX (HB) deficiency. The absence or the reduction of fVIII or fIX result in impaired thrombin generation and clot formation, causing excessive bleeding (mainly haemarthrosis). Osteoporosis is a systemic bone disease characterized by a low bone mineral density (BMD). A decrease of mean BMD has been described in haemophilic patients compared to healthy controls in several studies. So, osteoporosis could be an underestimated haemophilia-related comorbidity. None of the following risk factors (reduced physical activity, joint damage, vitamin D deficiency and /or hepatitis C virus (HCV) infection) has been retained as a cause of osteoporosis in haemophilic patients. Another hypothesis is that bone loss could be directly linked to fVIII or fIX and/or thrombin deficiency. The aim of this study is to evaluate the prevalence of the bone loss in HA and B patients, according to the type, the severity and the presence (or not) of a prophylactic treatment (depending on the age at which it was began) and to compare it to a control population. The investigators will also evaluate the relation between BMD and FVIII, fIX and thrombin potential.
The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.
The pivotal clinical data support prolonged dosing intervals of up to 14 days for routine prophylaxis in hemophilia B patients. The majority of adult and pediatric patients using Idelvion for routine prophylaxis had a median annualized spontaneous bleeding rate (AsBR) of 0.00. The majority (99%) of bleeding episodes were managed successfully with one or two infusions, and 94% of bleeds were controlled with only one infusion regardless of the cause or location. The rationale for this study is to collect the effectiveness and safety data of severe hemophilia B patients treated with Idelvion following institutional standard of care. It is the aim of this study to extend the results of the clinical trial program to a broader hemophilia B population, and to compare with current alternative factor IX treatments in Taiwan.
