Filter by:β-thalassemia is one of the most common single gene disorder in Southern China. The phenotypic severity of beta thalassemia widely varies from mild to severe forms. Patients with the same beta thalassemia genotype show wide phenotypic variability that ranges from moderate to severe disease due to various genetic modifiers of disease severity. The aim of this study is to looking for the genetic factors which could affect the severity of beta thalassemia.
The production of Hb F after birth is an important factor in modifying the clinical severity of beta thalassemia because an increased gamma-globin level will bind the additional a-globin and form Hb F. The objective of this project is to evaluate the association of Hb F level with phenotypic diversity of patients with beta thalassemia.
This is an international prospective registry of patients with Alpha thalassemia to understand the natural history of the disease and the outcomes of fetal therapies, with the overall goal of improving the prenatal management of patients with Alpha thalassemia.
The primary objective of this study is to evaluate a potential behavioral intervention (MED-Go app). To meet this objective, the researchers will conduct a pilot randomized controlled trial to test the feasibility and acceptability of MED-Go app in adolescents and young adults (AYA) with sickle cell disease (SCD). The long-term goal of this research is to promote medication adherence behavior and improve health outcomes in AYA with SCD.
Beta-thalassemias and hemoglobinopathies are serious inherited blood diseases caused by abnormal or deficiency of beta A chains of hemoglobin, the protein in red blood cells which delivers oxygen throughout the body.The diseases are characterized by hemolytic anemia, organ damage, and early mortality without treatment. Increases in another type of (normal) hemoglobin, fetal globin (HbF), which is normally silenced in infancy, reduces anemia and morbidity. Even incremental augmentation of fetal globin is established to reduce red blood cell pathology, anemia, certain complications, and to improve survival. This trial will evaluate an oral drug discovered in a high throughput screen, which increases fetal globin protein (HbF and red blood cells expressing HbF)and messenger ribonucleic acid (mRNA) to high levels in anemic nonhuman primates and in transgenic mice. The study drug acts by suppressing 4 repressors of the fetal globin gene promoter in progenitor cells from patients. The drug has been used for 50 years in a combination product for different actions - to enhance half-life and reduce side effects of a different active drug- and is considered safe for long-term use. This trial will first evaluate 3 dose levels in small cohorts of nontransfused patients with beta thalassemia intermedia. The most active dose will then be evaluated in larger subject groups with beta thalassemia and other hemoglobinopathies, such as sickle cell disease.
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)
This is a prospective, controlled, open-label, pharmacokinetic study. This study aims at studying the PK of sofosbuvir, ledipasvir and sofosbuvir metabolite (GS-331007) in HCV infected children with hematological Disorders. to develop predictive pharmacokinetic model for the 3 moieties in the studied population. In this study, patients in both treatment groups will receive 12 weeks of treatment with a fixed-dose combination tablet containing 400 mg of sofosbuvir and 90 mg of ledipasvir(SOF/LED) orally, once daily with food.
Hypothesis: Taurine, in combination with standard iron chelation therapy, is more effective than chelation therapy alone in reducing cardiac iron overload, oxidative stress and cardiac damage in β-Thalassemia. Protocol: Sixty subjects with transfusion dependent β-Thalassemia receiving deferasirox iron chelation therapy will be recruited and randomized in a 1:1 ratio to either (1) placebo and continuation of their iron chelation or (2) a combination of iron chelation plus taurine. Transfusion and safety visits will be scheduled monthly with clinical/biochemical assessment visits every three months. The efficacy of taurine combined with standard chelation therapy will be assessed at baseline and 12 months posttreatment by both cardiac T2*MRI, and cardiac function. The recruitment period is projected to be 12 months from initiation.
In β-thalassaemia and Sickle Cell Disease (SCD), a significant production of fetal haemoglobin (HbF) may reduce the severity of clinical course and reactivation of γ-globin gene expression in adulthood. HbF induction is one of the best strategies to ameliorate the characteristic symptoms of these diseases. Hydroxyurea (HU) is the only medication, approved by the US Food and Drug Administration, inducing HbF. However, treatments with HU induce sufficient HbF levels in only half of the patients, and side effects including leukopenia and neutropenia are frequently reported. Therefore, novel therapeutic inducers must be identified to develop a personalized treatment in β-thalassaemia and sickle cell anaemia. The availability of new treatments depends on drugs already approved for other indications, and on pharmacokinetics and pharmacovigilance already assessed. Rapamycin (as Sirolimus) is an immunosuppressant agent, approved by the FDA for acute rejection prevention in renal transplant recipients. The ability of this drug to induce γ-globin gene expression in erythroleukemia cell line and erythroid precursors cells (ErPCs) in ß-thalassaemia patients is already known. A clinical investigation on the effects of sirolimus in ß-Thalassaemia aims to evaluate several parameters related to red blood cell status and HbF levels and is a first step for the full clinical development in this new indication.
This is a Phase 2a study to evaluate the safety and pharmacokinetics (PK) of luspatercept in pediatric participants with β-thalassemia. The study will be conducted in 2 parts for both transfusion-dependent (TD) and non-transfusion-dependent (NTD) β-thalassemia participants: TD Part A will be in adolescent participants aged 12 to <18 years with two dose escalation cohorts, followed by a dose expansion cohort. NTD Part A will be conducted in the same age group participants as TD Part A with dose confirmation and expansion phase. After Part A TD participants have completed at least one year of treatment, all available safety data from Part A adolescent participants will be evaluated before initiating TD and NTD Part B in the age group from 6 to <12 years old. Part B will consist of two dose escalation cohorts for TD and two dose escalation cohorts for NTD. Upon completion of the Treatment Period, participants of any cohort who are benefiting from the study treatment, will be offered the opportunity to continue luspatercept treatment in the Long-term Treatment Period for up to 5 years from their first dose. Participants who discontinue study treatment at any time will continue in the Posttreatment Follow-up Period for at least 5 years from their first dose of luspatercept, or 3 years from their last dose, whichever occurs later, or until they withdraw consent/assent, are lost to follow-up, or the End of Trial, whichever occurs first.
