Filter by:A prospective, single-arm, intervention study of oral alendronate in adults with sickle cell disease and osteonecrosis
Background: Sickle cell disease (SCD) is an inherited blood disorder. The disease affects the ability of red blood cells to carry oxygen; this in turn can injure organs including the heart, lungs, and kidneys. SCD can lead to serious illness and death. Treatments such as bone marrow transplants and gene therapies can cure SCD, but they are not widely available. Current drug treatments for SCD are not always effective. This natural history study will examine how a study drug (mitapivat) affects red blood cells in people with SCD. Objective: To learn how mitapivat affects red blood cells in people with SCD. Eligibility: People with SCD who are enrolled in the parent study, NIH protocol IRB001565-H. Design: Procedures for this study will be done during visits already scheduled for the parent study. Participants will have additional blood drawn during study visits. The additional amount will be about 3.5 teaspoons. Participants will undergo a test called near infrared spectroscopy (NIRS) up to 9 times. Probes will be placed on their skin. A blood pressure cuff will be placed on their arm. The cuff will be filled with air for up to 5 minutes and then released. Participants may be asked to breathe at a certain rate or to hold their breath during these measurements. NIRS measures oxygen levels, blood flow, and the makeup of skin and muscle. Researchers will draw additional information for this study from participants medical records.
This is a single-dose, open-label study in participants with transfusion-dependent β-thalassemia (TDT) or severe sickle cell disease (SCD). The study will evaluate the safety and efficacy of autologous CRISPR-Cas9 modified CD34+ human hematopoietic stem and progenitor cells (hHSPCs) using CTX001.
Research Type: Clinical Trial Background: People with sickle cell disease (SCD) have many health challenges. Also, they often have trouble sleeping. Acceptance and commitment therapy (ACT) might help people with SCD to improve their sleep problems. Objective: To see how well ACT works in people with SCD and sleep problems and to find out how they feel about it. Eligibility: People between the ages of 18 and 55 with SCD and trouble sleeping. Design: The study is remote. Participants will not have to come to the NIH at all. They will need a device that has Bluetooth and can connect to the internet. Some participants will be in the study for 12 weeks. Others will participate for 20 weeks. Participants will video chat with an ACT coach once a week for 8 weeks. The coach will guide participants through mindfulness exercises and teach ACT ideas. Each session lasts about 45 minutes. Participants will be loaned an actigraph, a device worn on the wrist like a watch that measures and records movement. They will download a free app to upload data from the actigraph for the researchers. Participants will wear the actigraph on their nondominant wrist day and night for either 4 or 6 designated weeks. During these weeks, participants will complete a sleep diary each morning when they wake up. This takes about 2 minutes. Participants will be sent other surveys to complete from home during the study. They will answer questions about their physical and emotional health. These take 20-25 minutes. The last survey will be 4 weeks after participants finish the ACT treatment. They will answer questions about how helpful they thought ACT was and how easy or hard it was to wear the actigraph.
Background: Sickle cell disease (SCD) is an inherited disorder of the blood. It can damage a person s organs and cause serious illness and death. A blood stem cell transplant is the only potential cure for SCD. Treatments that improve survival rates are needed. Objective: To find out if a new antibody drug (briquilimab, JSP191) improves the success of a blood stem cell transplant Eligibility: People aged 13 or older who are eligible for a blood stem cell transplant to treat SCD. Healthy family members over age 13 who are matched to transplant recipients are also needed to donate blood. Design: Participants receiving transplants will undergo screening. They will have blood drawn. They will have tests of their breathing and heart function. They may have chest x-rays. A sample of marrow will be collected from a pelvic bone. Participants will remain in the hospital about 30 days for the transplant and recovery. They will have a large intravenous line inserted into the upper arm or chest. The line will remain in place for the entire transplant and recovery period. The line will be used to draw blood as needed. It will also be used to administer the transplant stem cells as well as various drugs and blood transfusions. Participants will also receive some drugs by mouth. Participants must remain within 1 hour of the NIH for 3 months after transplant. During that time, they will visit the clinic up to 2 times a week. Follow-up visits will include tests to evaluate participants mental functions. They will have MRI scans of their brain and heart.
This study will assess the performances of the Montreal Cognitive Assessment (MoCA) to screen for cognitive impairment in adults with sickle cell anemia. The results of the MoCA and its subscores will be compared to a standardized neuropsychological evaluation using validated tests.
A prospective study to determine how low bone mineral density and/or vertebral compression fractures associate with pain in adults with sickle cell disease
This is a study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of FTX-6058 in participants with sickle cell disease.
Sickle cell disease (SCD) is the most common genetic disease, affecting about 25 million people worldwide. Approximately 150,000 Nigerian children are born each year with sickle cell disease (SCD), making it the country with the largest burden of SCD in the world. Recent advancements in care for children with SCA have translated into improved survival of children in both high and low-resource settings. However, more complications of SCD are seen in those who survive to adulthood. Silent cerebral infarcts (SCI) and strokes are among the most devastating complications of SCD, affecting 40% and 10% of children, respectively. The overall goal of this study is to extend the Investigator's successful capacity-building effort in the assessment of neurological morbidity in children with SCD living in northern Nigeria (Kano) to young adults with SCD living in the same region. About 50% of all adults with SCD live in Nigeria. Despite the high prevalence of SCD in Africa, the neurological morbidity is not well characterized, limiting opportunities for primary and secondary stroke prevention strategies. At least 50% of young adults with sickle cell anemia (SCA), the most severe form of the disease, will have SCIs and an estimated 10% will have strokes, based on studies in high-resource settings. In high-resource settings, screening for abnormal transcranial Doppler (TCD) velocities in children with SCA, coupled with regular blood transfusion has resulted in a 92% reduction of relative risk for strokes. Despite this effective strategy, regular blood transfusion therapy does not seem sustainable in sub-Saharan Africa due to shortages and the risk of transfusion transmissible infections. Additionally, there is a lack of evidence-based stroke prevention strategies in young adults with SCA, either in the high-income or in low-resource settings. Based on the foregoing, the Investigators propose to determine the prevalence of neurological injury (overt stroke, transient ischemic attacks, and silent cerebral infarcts) in young adults at the transition age from 16-25 years. The Investigators will also, for the first time, assess conventional risk factors of stroke in the general population to determine whether a different prevention strategy is required to reduce the incidence of neurological injury in this high-risk population.
Sickle Cell Anemia (SCA) occurs in 300,000 newborns per year in the world, with 150,000 affected births in Nigeria, alone. With improvement in survival for children with SCA in both high- and low-resource countries, neurological morbidity is an emerging significant public health challenge, particularly in countries with a high rate of sickle cell disease (SCD). Both silent cerebral infarcts (SCI) and overt strokes result in significant neurological morbidity and premature death. Five NIH-funded randomized controlled trials (RCT) demonstrated that regular blood transfusion or hydroxyurea therapy are efficacious treatments for primary and secondary stroke prevention in children with SCA. Despite the observation that at least 99% of children with SCA in high-resource settings reach adulthood, and approximately 60% of adults will experience one or more strokes (~50% with SCI and ~10% with overt strokes) and the high disease-burden in Nigeria, the prevalence and incidence rates of new and recurrent stroke (overt and silent strokes)have not been collected systematically in children and young adults (16-25 years old) with SCA. In the last decade, there has been growing use of stroke registries in economically advanced nations, particularly for epidemiological purposes of trend analysis, clinical effectiveness, compliance to guidelines, assessment of implementation, adoption of novel techniques, and quality improvement process. For the first time in clinical centers in Nigeria, the Investigators will conduct an observational epidemiological study to document the prevalence and track the incidence of new and recurrent strokes in children and young adults with SCD. The Investigators will create a stroke registry referred to as the Afolabi Stroke Registry for Children and Young Adults with Sickle Cell Disease in Nigeria. The overall purpose of the stroke registry is to document the natural history of SCD in a low-resource setting and to improve the quality of the care of children and young adults with SCD living in Nigeria.
