Inherited hemoglobinopathy

This study is testing a milder type of stem cell transplant for people with non-cancerous blood, immune, or metabolic disorders. The goal is to safely get donor cells to grow in the patient's body while reducing harsh side effects. About 220 participants will receive a reduced-in…

This study tests a drug called SIL-8301 (senicapoc) in 105 adults with sickle cell disease who have low hemoglobin but few pain crises. Participants take the drug or a placebo daily for 24 weeks, along with their usual hydroxyurea. The main goal is to see if the drug raises hemog…

This trial tests a second stem cell transplant using a gentler conditioning regimen of busulfan, fludarabine, and low-dose total body irradiation. It is for people with blood disorders, hemoglobin diseases, or immune deficiencies whose first transplant did not achieve enough dono…

This study tests a new type of stem cell transplant for children with severe blood disorders like sickle cell disease or aplastic anemia. The transplant uses stem cells from a parent or other half-matched family donor, which are specially processed to remove certain immune cells.…

This phase 2 trial tests a stem cell transplant from a donor for people with high-risk sickle cell disease, thalassemia, and other red blood cell disorders. Participants receive drugs and low-dose radiation before the transplant to help the new cells take hold. The study will tra…

This study tests a bone marrow transplant from a family donor for children under 21 with severe non-cancer blood disorders like sickle cell disease, bone marrow failure, or immune problems. The goal is to see if the transplant can replace the diseased cells with healthy donor cel…

This study tests whether adding memory immune cells (CD45RO) to a stem cell transplant can help children fight off dangerous viral and fungal infections after the procedure. The transplant uses donor stem cells that have been stripped of certain cells to prevent graft-versus-host…

This study tests a one-time treatment called CTX001, which uses CRISPR gene editing to modify a patient's own stem cells to produce more fetal hemoglobin. The goal is to reduce or eliminate the need for blood transfusions in people with transfusion-dependent beta-thalassemia or s…

This study tests a cord blood transplant in children and young adults (up to age 21) with life-threatening blood cancers or non-cancer blood disorders who do not have a matched family donor. The goal is to see if this approach lowers the risk of death from treatment one year afte…

This long-term follow-up study tracks 50 patients with sickle cell disease who received the experimental gene therapy BEAM-101. The goal is to monitor safety, side effects, and overall health for up to 15 years after treatment. Participants will have regular check-ups to see how …

This study looks at whether a liquid medicine called Xromi (hydroxycarbamide) can safely prevent painful complications of sickle cell disease in children aged 9 months to 2 years. About 180 children will take part, with some receiving Xromi and a comparison group of similar child…

Researchers at St. Jude Children's Research Hospital are following people with hemoglobin disorders who have received a stem cell transplant or gene therapy. The study enrolls up to 200 participants who had or plan to have one of these treatments within 15 years. It collects rout…

This study provides ongoing check-ups for people who received a donor stem cell transplant at the NIH at least three years ago. Researchers will monitor for late side effects, disease return, and overall health. Participants will have yearly visits that may include blood tests, b…

This study aims to measure how long red blood cells survive in people with sickle cell disease, thalassemia, and other inherited blood disorders. Researchers will take a blood sample, label the red cells with biotin (a vitamin), and infuse them back into the participant. Over up …

This study collects blood samples and health information from 375 people with non-cancerous blood disorders like aplastic anemia, sickle cell disease, or thalassemia who are receiving a stem cell transplant or gene therapy. The goal is to create a biobank that helps researchers u…

This study collects bone marrow that is normally thrown away during surgery from people with and without blood disorders like sickle cell disease. Researchers will use these samples in the lab to learn how to better manipulate stem cells for gene therapy and to study cell health.…

This study looks at 350 adults with transfusion-dependent beta-thalassemia to find differences between those who have atrial fibrillation (a type of irregular heartbeat) and those who do not. Researchers will compare clinical tests, lab results, and imaging to better understand t…

This study is for people with sickle cell disease or other rare anemias. Researchers want to use advanced genetic and blood tests to better understand each person's condition. The goal is to make diagnosis more precise so that treatments can be tailored to each patient. About 200…
