Sickle Cell Disease Clinical Trials

'Sickle-shaped' anemia was first clinically described in the US in 1910, and the mutated heritable sickle hemoglobin molecule was identified in 1949. The pathophysiology of SCD is a consequence of abnormal polymerization of sickle hemoglobin (HbS) and its effects on red cell membrane properties, shape, and density, and subsequent critical changes in inflammatory cell and endothelial cell function. Our goal is to understand the impact of CMA abnormalities in SCD, by interrogating a number of recognized interactions in a range of clinical phenotypes. To date, correlative studies in SCD, by us and others, have range between clinical reports, based on tests, interventions, and chart review of individuals or groups of individuals and, at the other extreme, identification of functional gene polymorphisms based on population studies. The investigators wish to augment these studies through a systematic examination of cellular membrane properties and activation status. Of hematologic disorders, SCD may be unusually susceptible to such an examination. Read Less

This is a multi-site, multi-visit feasibility RCT of music therapy (MT) among adolescent and adult patients (aged 14 and older) with sickle cell disease (SCD). Subjects will be randomized into one of three groups, either (1) 6 visits of in- person MT (InMT:); (2) 1 visit of in-person MT and 5 visits of virtual MT (HybMT); or (3) 1 visit of in-person health education and 5 visits of virtual health education (HybHE). Cohorts of 15 participants (10 at site 1 and 5 site 2) will be recruited each quarter for 6 quarters to reach 90 participants. Cohorts will maintain a semi-structured recruitment, consenting, assessment, and intervention schedule. The primary objective of the study is to examine the feasibility of study. This is defined by 6 metrics: (1) completeness of data collection, (2) participant screening, (3) participant recruitment, (4) participant retention, (5) Individual attendance and (6) Home practice. A final determination of "feasibility" for the study will be met if any 4 of the 6 metrics described above are met. This study will also include a secondary objective of conducting qualitative interviews to assess feasibility of implementation. Read Less

This study is a pilot, phase II, open-label study of the angiotensin II receptor blocker, losartan, in patients with Sickle Cell Disease (SCD) 6 years or older for 12 months. The investigators will enroll 24 patients with SCD over the course of 1 year with a goal to complete all study procedures in 2 years. The short-term goal is to obtain clinical pilot data regarding the safety and efficacy of losartan in stabilizing or decreasing extracellular volume fraction (ECV) after 12 months of therapy.

This study will collect representative blood samples from healthy children and adults and from children and adults who have unique red blood cell features that are related to sickle cell disease. Sickle cell disease is a blood disease that limits the ability of red blood cells to carry oxygen throughout the body. The purpose of the study is to collect a variety of blood samples that may then be used to investigate advances and potential new drug treatments for sickle cell disease. Volunteers must be at least 18 years of old. Samples will be taken both from healthy volunteers and from volunteers who have unique red blood cell features that are related to sickle cell disease. Candidates will be screened with a medical history. During the study, participants will undergo a one- to two-hour outpatient procedure at the National Institutes of Health Clinical Center. Once researchers have explained the study and obtained the participant s consent, participants will donate 8 cc (approximately 2 teaspoons) of blood. Because repeat testing helps researchers validate study findings, participants who have the unique red blood cell features mentioned above may also be asked if they are willing to return and donate another 2 cc to 8 cc of blood for additional studies. The amount of blood drawn will not exceed 50 ml with any eight-week period for adults or 7 cc within any six-week period for children. Read Less

A phase III, multi-center, randomized, placebo-controlled, double-blind study to assess efficacy and safety of crizanlizumab (5 mg/kg) versus placebo, with or without hydroxyurea/hydroxycarbamide therapy, in adolescent and adult Sickle Cell Disease patients with frequent vaso-occlusive crises.

The main purpose of this study is to compare the effect of tebapivat versus placebo on anemia and to detect a dose-response for hemoglobin (Hb) response in participants with SCD. Read Less

This is a multi-center multi-national rollover study to allow continued access to crizanlizumab for patients with sickle cell disease (SCD) who are on crizanlizumab treatment in a Novartis-sponsored study (parent study) and are benefiting from the treatment as judged by the investigator. Read Less

Background: Sickle cell disease (SCD) is a genetic disease that causes the body to produce abnormal ( sickled ) red blood cells. SCD can cause anemia and life-threatening complications in the lungs, heart, kidney, and nerves. People with SCD are also at increased risk of forming blood clots in the veins and lungs, but the standard treatments for these clots can cause increased bleeding in people with SCD. Better treatments are needed. Objective: To test a drug (fostamatinib) in people with SCD. Eligibility: People aged 18 to 65 with SCD. Design: Participants will have 6 clinic visits over 12 weeks. Each visit will be 2 to 3 hours. Participants will be screened. They will have a physical exam with blood tests. They will tell the researchers about the medications they take. Fostamatinib is a tablet taken by mouth. Participants will take the drug at home, twice a day, for up to 6 weeks. Participants will have a clinic visit every 2 weeks while they are taking the drug. At each visit they will have a physical exam with blood tests. They will talk about any side effects the drug may be causing. If they are tolerating the drug well after the first 2 weeks, they may begin taking a higher dose. Participants will have a final visit 4 weeks after they stop taking the drug. They will have a physical exam and blood tests; they will be checked for any side effects of the drug. Read Less

The study, known as the Peer suppoRt for adolescents and Emerging adults with Sickle cell pain: promoting ENgagement in Cognitive behavioral thErapy (PRESENCE), aims to determine the effectiveness of digital CBT in reducing pain, opioid use, and healthcare utilization among AYAs with SCD. It also seeks to understand the role of personalized peer support in enhancing engagement and outcomes of digital CBT interventions. By leveraging existing infrastructure for delivering virtual peer support interventions, tailored digital CBT programs for individuals with SCD, and partnerships with CBOs, the study aims to provide valuable insights into the feasibility and effectiveness of digital CBT as a pain management strategy for this vulnerable population.

Background: Blood disorders like sickle cell disease and malaria affect many people around the world. Researchers want to learn more about blood disorders. To do this, they need to collect biological samples from people with blood disorders. They also need to collect samples from healthy people. Objective: To collect samples to use for research on blood disorders. Eligibility: People ages 18-70 who have blood disorders. Healthy volunteers without blood disorders are also needed. Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will give one or more samples. They will give them over 5 years. They can choose not to give any of the samples: Saliva: Participants will spit into a tube. They may also have the inside of their mouth swabbed. Urine: Participants will urinate into a cup. Blood and blood waste products: Blood will be taken through a needle in the participant s arm. Fat samples: An area on the participant s belly or buttock will be numbed. A small cut will be made into the skin and a small piece of fat removed. Mucus and cells from the lungs: The participant will be sedated. A flexible tube will be inserted through the nose or mouth into the lung airways. These participants will also have a physical exam, chest x-ray, and heart tests after the procedure. Read Less
