Sickle Cell Anemia (HbSS, or HbSβ-thalassemia0) clinical trials
Below are recruiting sickle cell anemia (hbss, or hbsβ-thalassemia0) clinical trials, each written for real people, not researchers. We’re tracking 13 recruiting studies, each written for real people, not researchers, below.
Recruiting studies
- NCT06647979RecruitingPhase 1
Gene editing for severe sickle cell or thalassemia
This trial tests a new gene therapy that edits your own blood stem cells to help them make more fetal hemoglobin, which can prevent sickling and reduce the need for transfusions. It is for people with severe sickle cell disease or beta thalassemia who do not have a matched sibling donor.
Boston, MassachusettsAges 13–40 - NCT07175051RecruitingPhase 2
Testing a kidney-protecting drug in sickle cell disease
This study tests whether empagliflozin, a medicine that protects the kidneys in people with diabetes, can also protect the kidneys in people with sickle cell disease. The goal is to see if it can reduce protein in the urine, which is a sign of kidney stress.
Chicago, IllinoisAges 18–60 - NCT07177300RecruitingPhase 4
Hydroxyurea for sickle cell disease in children
This trial tests different ways to start hydroxyurea for children with sickle cell anemia. The goal is to find the safest and most effective approach to help manage symptoms and prevent complications.
Cincinnati, OhioAges 6 months+ - 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 - NCT06481306RecruitingPhase 1/Phase 2
Testing a new drug for sickle cell disease in healthy people and patients
This early-phase study tests a new drug (BMS-986470) for people with sickle cell disease who have frequent pain crises. The goal is to see if it can safely reduce crises. It includes a small group of healthy volunteers as well.
Birmingham, AlabamaAges 18 years+ - NCT07566494RecruitingPhase 1
Testing VAS-101 for sickle cell disease
This early-phase trial tests a new drug called VAS-101 for people with sickle cell disease. It aims to find a safe dose and see how the drug affects the body.
Bethesda, MarylandAges 18–90 - NCT05285917RecruitingPhase 3
Hydroxyurea safety study for young children with sickle cell
This trial tests a way to use hydroxyurea more safely and effectively in children with sickle cell anemia. It may help doctors fine-tune dosing to reduce complications and side effects.
LuandaAges 6 months–12 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 - 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 - 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 - 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 - 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

Common questions
- Are there clinical trials for sickle cell anemia (hbss, or hbsβ-thalassemia0)?
- Yes. Clin2 currently lists 13 recruiting sickle cell anemia (hbss, or hbsβ-thalassemia0) 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 (hbss, or hbsβ-thalassemia0) 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 (hbss, or hbsβ-thalassemia0) 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.
