Filter by:The study consists in collecting umbilical cord blood cells from newborns at risk of sickle cell disease, to perform laboratory experiments aiming to characterize the cells with HbS/HbS mutation, to develop methods to prepare, to gene-modify and to preserve these cells.
FT-4202 is an oral small-molecule agonist of pyruvate kinase red blood cell isozyme (PKR) being developed for the treatment of hemolytic anemias. This initial study will characterize the safety, tolerability and the pharmacokinetics/pharmacodynamics (PK/PD) of a single ascending dose and multiple ascending doses of FT-4202 in the context of Phase 1 studies in healthy volunteers and sickle cell disease patients. The effects of food on the absorption of FT-4202 will also be evaluated in healthy volunteers.
This study evaluates the safety of defibrotide in subjects with sickle cell disease (SCD)-associated acute chest syndrome (ACS).
An open label, safety and pharmacokinetic study of oral hydroxyurea solution administered to children from 6 months to 17.99 years (i.e. to the day before 18th birthday), with a 12 to 15 month treatment period for each participant. The study treatment duration will be for 6 months at the maximum tolerated dose [MTD], which is usually reached by 6 months after initiation of treatment. For patients in whom time to MTD is longer than 6 months or not achieved at all, the maximum duration of study treatment will be 15 months.
The study team proposes a triple-blind, placebo-controlled, phase II clinical trial of once-daily inhaled mometasone for 48 weeks (with 4-week washout at study completion) in individuals with Sickle Cell Disease (SCD) who report episodic cough or wheeze (ECW) but do not have asthma. Patients will be recruited from and followed in SCD clinics at participating sites. The primary endpoint will be a reduction in sVCAM level of 20% or more in comparison to placebo.
This study is designed to describe the safety, tolerability, and immunogenicity of V114 in children with sickle cell disease.
This mixed-methods study aims to understand the implementation of a previously tested, efficacious social determinants of health (SDoH) screening and referral intervention in the outpatient pediatric hematology setting; qualitatively assess possible mechanisms for such interventions on improving child health; and obtain population-specific empirical estimates to plan a large-scale clinical trial.
This is primarily an observational trial in patients with chronic anemia syndromes (sickle cell disease and thalassemia) and control subjects. The key purpose is to understand how brain blood flow reserve (the ability of the brain to increase its flow in response to stress) is altered in patients with chronic anemia. Since this parameter may depend on anemia severity, we will perform the MRI monitoring prior to and following clinically indicated transfusions in a subset of patients. Most patients will already be prescribed hydroxyurea as part of their standard of care. Since hydroxyurea could impact brain blood flow, there is also a small pilot study (20 patients, nonrandomized, open label) where MRI imaging will be performed prior to and following administration of hydroxyurea up to maximum tolerated dose. The study will enroll 90 adult subjects with transfusion independent sickle cell disease (70 SS, 10 SC, 10 Sβ0) and 60 patients with transfusion-dependent sickle cell disease. It will also include 10 transfusion independent thalassemia patients and 20 transfusion dependent thalassemia patients as well as 40 control subjects recruited from first degree relatives of the sickle cell disease population. All eligible subjects will be asked to provide informed consent before participating in the study.
Background: Sickle cell disease is an inherited blood disorder. People with this disease have a problem with their hemoglobin. That is a protein in red blood cells that carries oxygen in the body. Some people with this disease are enrolled in research at NIH. Researchers want to learn more about the thoughts and opinions of those people. This may improve the way researchers explain clinical studies, risks, and benefits to people with the disease. Objective: To learn about the motivations, decisions, and experiences in clinical research of people with sickle cell disease. Eligibility: Adults ages 18 and older who have sickle cell disease. They must be in an NIH study on this condition. They must have been invited to join either a gene therapy or peripheral blood stem cell transplantation study. Design: Participants will have 1 interview. It will be done in a quiet room in the NIH Clinical Center or by video call. It will take about 60 minutes. The interview will be audio-recorded if the participant agrees. Participants will be asked about: - Their experiences with and thoughts on sickle cell disease - Their decision to participate in clinical research - Factors that may have affected their decision to participate. These may include family, disease history, or faith. Participants may complete a few brief questionnaires.
Sickle cell anaemia is an inherited blood disorder which results in abnormal sickle shaped red blood cells which do not fit well through small blood vessels. These blockages prevent oxygen (in blood) from reaching different parts of the body resulting in painful crisis. This study will compare the effectiveness of two types of pain medication, one given through a vein and one squirted up the nose.
