Hemolytic anemia due to pyrimidine 5' nucleotidase deficiency

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 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 phase 2 trial tests a combination of three chemotherapy drugs (treosulfan, fludarabine, thiotepa) plus an immune-suppressing antibody before a donor stem cell transplant in up to 40 people under 50 with non-cancerous blood disorders. The goal is to see if this milder conditi…

This expanded access program offers a stem cell transplant using donor cells that have been specially processed to remove certain immune cells, reducing the risk of graft-versus-host disease. It is for patients with serious blood disorders, immune deficiencies, or metabolic disea…

This early-stage study tests a new drug called APG-5918 in healthy volunteers and people with anemia (low red blood cells). The main goal is to check safety and how the body handles the drug, while also seeing if it can raise hemoglobin levels. About 105 participants will take pa…

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 learn more about rare disorders that affect how the body processes chemicals called pyrimidines and purines. These disorders can cause problems in the brain, blood, kidneys, and immune system, ranging from mild to life-threatening. Researchers will compare test…

This study looks at whether doctors at Siriraj Hospital follow a new guideline for treating anemia in patients before major surgery. Anemia is common in surgical patients and can lead to more blood transfusions and worse outcomes. The researchers will track 93 anemic patients to …

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 is observing 1000 adults having moderate- to high-risk surgery to see if the type and severity of anemia they have before surgery affects their risk of complications like heart injury, kidney injury, or stroke. Researchers will compare patients with iron-deficiency ane…
