Recruiting studies
- NCT05376046Recruiting

Sickle cell care plan choices for teens and young adults
This trial tests a way to help teens and young adults with sickle cell disease (SCD) and their caregivers actively take part in treatment decisions. It focuses on improving shared decision-making through interviews and a partner-centered approach.
Wilmington, DelawareAges 15 years+ - NCT05392894RecruitingPhase 3
Transplant using a half-matched donor for severe sickle cell
This trial tests whether a half-matched (haploidentical) blood stem cell transplant can treat adults with severe sickle cell disease. It may help reduce serious complications and improve survival, but it requires a fit health status and specific donor and medical conditions.
LondonAges 18 years+ - NCT05477563RecruitingPhase 3
One-time gene therapy for severe sickle cell and transfusion anemia
This trial tests a single dose of gene therapy (CTX001) to improve outcomes for people with severe sickle cell disease or transfusion-dependent beta-thalassemia. It aims to see how well it works and whether it is safe, especially after a planned stem cell transplant process.
New York, New YorkAges 12–35 - NCT05519111RecruitingPhase 2
Cannabinoid treatment to lower inflammation and sickle pain
This Phase 2 study tests a cannabinoid medicine (dronabinol) to reduce inflammation and pain related to sickle cell disease. It may help you have less pain that interferes with daily life if you meet the study requirements and can safely avoid cannabis during the study.
New York, New YorkAges 18 years+ - NCT05583721RecruitingPhase 2
PET scan study of heart filling and blood flow in sickle cell
This study uses a PET scan to look for links between abnormal heart “filling” problems and how well blood reaches the heart muscle in people with sickle cell disease. The results may help explain early heart changes in sickle cell and guide future care.
Memphis, TennesseeAges 18–21 - NCT05736419RecruitingPhase 2
Immune-suppressing treatment before stem cell transplant for blood disorders
This Phase 2 study tests an immune-suppressing treatment for people with sickle cell disease or beta-thalassemia who are preparing for a stem cell transplant from a donor. It aims to help the transplant work better by changing the immune response.
Basking Ridge, New JerseyAges 2–50 - NCT05748717Recruiting
Tests blood flow in children with sickle cell
This study measures how well blood flows through brain arteries in children with sickle cell disease using a noninvasive ultrasound test. It may help doctors better understand stroke risk and how treatments like hydroxyurea or recent care affect blood flow.
Kingston, Saint Andrew ParishAges 4–16 - NCT05810181Recruiting
Interviews to improve choices about gene therapy for rare diseases
This study uses one-on-one interviews to learn what families and clinicians need to make decisions about gene therapy for rare diseases. The goal is to create or improve decision tools that make gene therapy information easier to understand and act on.
Memphis, TennesseeAges 8 years+ - NCT05904093RecruitingPhase 1
Check if increasing fostamatinib doses are safe in sickle cell
This Phase 1 study tests whether increasing doses of fostamatinib are safe and tolerated in adults with stable sickle cell disease. It may help researchers understand if the drug could be a future treatment option for people with stable sickle cell.
Bethesda, MarylandAges 18–65 - NCT05953584RecruitingPhase 2
Etavopivat for preventing stroke risk in sickle cell children
This trial studies etavopivat to see if it can improve blood-flow measurements in the brain that predict future stroke risk in children with sickle cell disease. If you qualify, you would take the study medicine and be monitored with brain blood-flow testing.
Raipur, ChhattisgarhAges 12–16 - NCT06071377Recruiting
Learning About Health in People With Sickle Cell Trait
This study is for adults who have or might have sickle cell trait (carrying the sickle cell gene but not the disease). It aims to understand the health effects of sickle cell trait over time by following participants and collecting health information.
Birmingham, AlabamaAges 18 years+ - NCT06139510Recruiting
Understanding Pain in Sickle Cell Disease
This study looks at what causes pain in people with sickle cell disease. They hope to learn more about pain patterns to better help patients manage it.
Durham, North CarolinaAges 15–40 - NCT06184126Recruiting
Virtual reality for sickle cell pain in the emergency room
This trial tests whether using a virtual reality (VR) headset, along with your usual pain treatment, can help reduce pain during a sickle cell crisis. It is for adults with sickle cell disease who are in the emergency department and receiving IV opioids for a vaso-occlusive crisis.
Baltimore, MarylandAges 18 years+ - NCT06198712RecruitingPhase 2
Testing etavopivat in children with sickle cell disease
This trial tests a new drug, etavopivat, to see how it works in children with sickle cell disease. It may help reduce painful crises and other complications.
Toronto, OntarioAges 6 months–18 years - NCT06260891RecruitingPhase 2
Zinc study for sickle cell disease and bone health
This study tests if taking zinc supplements can improve bone health in people with sickle cell disease. It's for those with certain types of sickle cell disease (SS or S-Beta zero thalassemia) who are not on chronic transfusions or zinc supplements.
Oakland, CaliforniaAges 15–40 - NCT06313398RecruitingEarly Phase 1
Measuring red blood cell lifespan in sickle cell disease
This study uses a harmless vitamin (biotin) to label your red blood cells and track how long they survive. It aims to understand how different blood disorders affect red blood cell lifespan, which may help improve treatments.
Bethesda, MarylandAges 18–100 - NCT06318143Recruiting
Increasing use of hydroxyurea for sickle cell in Nigeria
This study aims to help more people with sickle cell disease in Nigeria start taking hydroxyurea, a medicine that can prevent pain crises and other complications. It will work with clinics to make it easier for patients to get and stay on this treatment.
AbujaAges 1 year+ - NCT06358638RecruitingPhase 2
Sickle cell transplant using a gentler approach for patients with donor antibodies
This trial is testing a new, gentler type of bone marrow transplant for children and young adults with sickle cell disease who have a healthy sibling donor with a mismatched blood type or who have antibodies against their donor's red blood cells. The goal is to replace the faulty bone marrow with healthy donor cells, with fewer side effects than traditional transplants.
