Filter by: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)
Pain is the primary complication of sickle cell disease (SCD), including vaso-occlusive crises and more persistent, chronic pain. SCD-related pain is associated with significant functional impairment, spanning poor school attendance, decreased quality of life, and stress and mood difficulties. Pharmacological approaches are the first-line treatment for SCD-related pain, but these can be costly and have unwanted side effects. Given limitations from pharmacological approaches and the influence that poor behavioral responses have on disease management and health outcomes suggest a critical need for alternative and adjunctive treatments. Due to gaps in available behavioral treatments specifically designed for addressing common challenges associated with pain management in pediatric SCD, the investigators developed a manualized behavioral therapy protocol by tailoring existing evidence-based treatments. The overall goal of the intervention is to reduce the impact of pain on daily functioning in pediatric SCD. This study will empirically test the feasibility and preliminary efficacy of this intervention for youth with SCD. Children and adolescents with SCD between the ages of 8 and 17 years old (n=20) will be recruited to complete the treatment protocol. Feasibility will be assessed by examining participation and program completion rates, as well as feedback from a treatment acceptability questionnaire and qualitative interview. Participants will complete baseline assessments, weekly questionnaires, and post-treatment assessments (post-intervention assessment, follow-up time points: 1-month following the intervention, and 3-months following the intervention).
The investigators will attempt to develop a more accurate equation to estimate eGFR in pediatric and adult sickle cell patients
This study is being done to test a transplant method that may have fewer side effects (or less toxic, less harmful) than conventional high dose chemotherapy conditioning-based transplants for children and young adults with Sickle Cell Disease (SCD). Patients less than or equal to 25 years old with SCD who would likely benefit from allogeneic hematopoietic cell transplantation (HCT) will be included in this study. Patients with a suitable HLA matched sibling donor (MSD) will be enrolled on the MSD arm while patients without an eligible MSD who have a suitable haploidentical (HAPLO) donor available will be enrolled on the HAPLO arm of the study. Primary Objective To assess the donor T-cell chimerism at 1-year post transplant in each respective arm (MSD, HAPLO) of the trial. Secondary Objectives - Assess the overall survival and 1-year, 2-year and 3-year post-transplant graft versus host disease (GVHD)-free SCD-free survival. - Estimate the primary and secondary graft rejection rate at 1-year, 2-year and 3-year post- transplant. - Estimate the incidence and severity of acute and chronic (GVHD). - Estimate the incidence of SCD recurrence after transplant - Assess the neutrophil and platelet recovery kinetics post-transplant. Exploratory Objectives - Record immune reconstitution parameters, including chimerism analysis, quantitative lymphocyte subsets, T cell receptor excision circle (TREC) analysis, V-beta spectratyping, and lymphocyte phenotype and function. - Conduct longitudinal examination of impact of HCT on patient health-related quality of life (HRQL) and adjustment, and parental adjustment. - Examine impact of HCT on patient cognitive and academic function. - Determine factors that influenced the decision to undergo HCT, explore perceptions of the HCT experience, and assess decisional satisfaction/regret. - Develop and evaluate an objective/quantitative imaging biomarker to assess organ (liver and heart) function/disease status and changes following HCT. - Develop and evaluate an objective/quantitative imaging biomarker to determine cerebral blood flow and oxygen extraction fraction following HCT.
Background: Venous thromboembolism (VTE) includes the abnormal clotting of blood in a deep vein of the upper or lower limbs (deep vein thrombosis) that may travel to and block a blood vessel in the lung (pulmonary embolism). Some people with sickle cell disease (SCD)-a red blood cell disorder-seem to be at greater risk for developing these blood clots. Researchers want to study the blood of people with SCD and VTE as well as healthy people to develop better treatments to prevent blood clots. Objective: To study blood clotting in SCD because it is the most common cause of vascular death after a heart attack or stroke. Eligibility: People ages 18-80 who have SCD (with or without a history of blood clots) or the trait for SCD, and healthy volunteers Design: Participants will be screened with medical history, physical exam, and medical records review. They will give blood samples. Participants will have phone calls either every 3 months or once a year, for 2 years. They will give updates on their health. They may give additional medical records. The phone calls may last up to 30 minutes. If participants have a VTE or pain crisis episode, they may visit the Clinical Center. These visits may last up to 4 hours. They will repeat the screening tests and give blood samples. Some participants may be invited to take part in blood studies. After 2 years, some participants will have a follow-up visit at the Clinical Center. Participation will last for about 2 years.
This study is a single center, prospective exploratory pilot study of Sickle Cell Anemia (SCA) participants. The study will enroll patients with early stages of sickle cell nephropathy (Chronic Kidney Disease (CKD) stage 1 or 2) who are at the highest risk of CKD progression (presence of both hemoglobinuria and urine albumin concentration ≥ 30 mg/g creatinin
The aim of the present study is comparing the effectiveness of different treatment regimens for investigating the therapeutic potential for each one in management of Vaso-occlusive pain in pediatric sickle cell disease. In addition, investigators apply the Cost-effectiveness analysis (CEA) as a form of economic analysis that compares the relative costs and outcomes (effects) for different treatment regimens on vaso-occlusive painful crisis.
Sickle cell disease is the most common single-gene disease in the world. Its prevalence is increasing in France, with patients' life expectancy increasing into developed countries. It mainly affects populations originating from sub-Saharan Africa. Among the chronic bone complications associated with sickle cell disease, osteoporosis has previously been highlighted but remains a poorly known complication in this very particular context. A dedicated evaluation of osteoporosis and associated risk factors in sickle cell disease patients living in France may enable better bone management of these patients in the future, as this problem, specific to their disease, is likely to become more frequent as their life expectancy increases. This is a prospective interventional and monocentric study whose objective is to describe the prevalence of osteoporosis in black patients with sickle cell disease in France
This is a non-randomized, open-label, multi-site, single-dose, Phase 3 study in approximately 35 adults and pediatric subjects ≥2 and ≤50 years of age with sickle cell disease (SCD). The study will evaluate hematopoietic stem cell (HSC) transplantation (HSCT) using bb1111 (also known as LentiGlobin BB305 Drug Product for SCD).
The purpose of this study is to compare the effect of ticagrelor vs placebo for the reduction of Vaso-Occlusive crises in paediatric patients with Sickle Cell Disease
