Recruiting studies
- NCT06635902RecruitingPhase 2
Citrulline for sickle cell pain crisis
This trial tests if an intravenous medication called L-citrulline can help treat pain crises in children and young adults with sickle cell disease. Participants receive either the study drug or a placebo while in the hospital for a severe pain episode.
Washington D.C., District of ColumbiaAges 4–21 - NCT07090668Recruiting
Ear stimulation for pain in sickle cell disease
This trial tests a safe, non-drug device that gently stimulates the ear to help reduce pain in children with sickle cell disease who are in the hospital for a pain crisis. It may offer a new way to manage pain without extra medication.
Atlanta, GeorgiaAges 7–18 - NCT07656415RecruitingPhase 3
Study of mitapivat for sickle cell disease patients who need blood transfusions
This study tests whether a daily pill called mitapivat can reduce the number of blood transfusions you need. It is for people with sickle cell disease who have had at least one transfusion in the past year and are not on regular transfusion therapy.
Indianapolis, IndianaAges 12 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 - NCT04099966RecruitingPhase 2
Stem cell transplant to treat high-risk blood cancers
This trial tests a specialized donor stem cell transplant to treat high-risk problems in the blood and bone marrow, including some cancers and non-cancers. It may help by using donor immune cells designed to better control the disease after transplant.
Valhalla, New YorkAges 1 day–30 years - NCT06290401Recruiting
Boosting self-management in teens with sickle cell disease
This study is testing a program to help adolescents with sickle cell disease better manage their health. It looks at how family, friends, and the clinic can support teens to take charge of their care.
Wilmington, DelawareAges 13–21 - NCT06529874Recruiting
Pain, balance, and strength in children with sickle cell
This study looks at how children (ages 9-14) with sickle cell anemia or who are healthy handle pressure, balance, and strength. It aims to understand pain and movement better to help improve care.
GizaAges 9–14 - NCT07116772Recruiting
Fertility experiences in sickle cell anemia
This study looks at fertility in people with sickle cell anemia. It aims to understand how the disease and its treatments affect fertility over time.
Santo DomingoAges 8 years+ - NCT05777993Enrolling by invitationPhase 4
Continued access to mitapivat for prior study participants
This study provides continued access to the drug mitapivat for people who have already been in a mitapativ study and are benefiting from it.
Anderlecht, Brussels CapitalAges 18 years+ - NCT06689800Recruiting
Family communication tool for kids getting transplant or cell therapy
This study looks at a family communication tool for children and teens getting stem cell transplants or cellular therapy. It helps families talk about treatment together.
St Louis, MissouriAges 8 years+ - NCT07432867RecruitingPhase 1/Phase 2
Gene therapy for severe sickle cell disease in teens and adults
This trial tests a new gene therapy for sickle cell disease. It uses your own blood stem cells (collected from bone marrow) that are modified in a lab to help produce healthy red blood cells, then given back to you after a short chemotherapy. The goal is to reduce or stop severe complications like pain crises and lung problems.
Paris, Île-de-France RegionAges 12–35 - NCT07015684RecruitingPhase 1
Radioactive antibody and transplant for advanced sickle cell disease
This trial tests a radioactive antibody (131I-apamistamab) as part of conditioning before a stem cell transplant from a matched sibling donor. It aims to make the transplant safer and more effective for people with severe sickle cell disease.
New York, New YorkAges 12–50 - NCT07206095Recruiting
Better diagnosis for inherited red blood cell diseases
This trial aims to improve how doctors diagnose rare inherited anemias, including sickle cell disease and other conditions that destroy red blood cells. It may help if you have a confirmed or suspected diagnosis but need more clarity through advanced testing.
Barcelona, BarcelonaAges Any age - NCT06439082RecruitingPhase 3
Crizanlizumab for sickle cell pain crises
This trial tests whether crizanlizumab can reduce painful sickle cell crises (called vaso-occlusive crises or VOCs) in people with sickle cell disease who have frequent crises. It may be an option for those who still have crises despite current treatments.
Birmingham, AlabamaAges 12–100 - NCT02720679Recruiting
Study genetics behind blood disorders in children and families
This study looks at genetic (DNA) factors that may contribute to certain blood disorders. You may be invited if you or a close family member is receiving care for a blood condition like MDS or MPN, and the study also includes related relatives.
Memphis, TennesseeAges Any age - NCT04008368RecruitingPhase 1/Phase 2
Second stem cell transplant for sickle cell with declining donor cells
This Phase 1/2 study tests whether repeating a stem cell transplant can help people with sickle cell disease (SCD) whose donor cells are no longer holding strong. It may help restore healthier blood cell production and reduce symptoms such as pain crises and severe anemia.
Bethesda, MarylandAges 2–80 - NCT06872333RecruitingPhase 2
Stem cell transplant from a matched sibling for blood disorders
This trial tests whether a stem cell transplant from a fully matched sibling donor can help people with serious blood disorders like sickle cell disease or thalassemia. It aims to replace the faulty blood system with a healthy one from the donor.
Minneapolis, MinnesotaAges Up to 55 years - NCT07776444Recruiting
Measuring brain blood flow with light and MRI
This study uses a special light-based device and MRI to measure how blood vessels in the brain respond to changes. It may help researchers better understand blood flow in people with and without sickle cell disease.
St Louis, MissouriAges 6–70 - NCT03937817Recruiting
Donate samples to study globin gene variants
This study collects common body samples to learn how different globin gene variants work and how they relate to health. Your samples may also be used later for new research, including genetic testing.
Bethesda, MarylandAges 18–70 - NCT04157179Recruiting
MRI study of brain oxygen use in children and adults
This study uses an MRI scan to measure how your brain uses oxygen. It includes healthy participants and people with sickle cell disease or who previously needed ECMO, which may help researchers understand brain oxygen problems and how to monitor them.
St Louis, MissouriAges 3–50 - NCT00047996Enrolling by invitation
Blood Donation Study for Blood Vessel Research
This study collects blood and urine samples from adults to help researchers understand diseases affecting blood vessels. Your donation helps scientists develop better treatments.
Bethesda, MarylandAges 18–100 - NCT04356469RecruitingPhase 2
Donor stem cell transplant for serious blood disorders in children
This trial tests a special type of donor stem cell transplant (with donor T-cells removed) to treat serious non-cancer blood problems in children. It may help by resetting the bone marrow so the body can make healthy blood cells again.
St. Petersburg, FloridaAges birth–21 years

Common questions
- Are there clinical trials for sickle cell anemia?
- Yes. Clin2 currently lists 46 recruiting sickle cell anemia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a sickle cell anemia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a sickle cell anemia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
