Male or female, aged 18 years or greater with confirmed diagnosis of SCD (all genotypes), thalassemia (beta and\u002For alpha), or other inherited hemoglobinopathy not otherwise specified.\n4. Be at steady state for their underlying disease (e.g. SCD or thalassemia) or post-bone marrow transplantation status, as evidenced by medical history.\n5. Ability to have blood samples drawn.\n6.

Female subjects of child-bearing potential must agree to use a medically acceptable method of birth control such as an oral contraceptive, intrauterine device, barrier and spermicide, or contraceptive implant\u002Finjection from start of screening through 4 months after infusion.\n7.

SCD causes red blood cells (RBCs) to die early. This can lead to a shortage of healthy cells. SCD and other blood disorders can be managed with drugs or cured with a bone marrow transplant. Researchers want to know how long RBCs survive in people with SCD and other blood disorders before and after treatment compared to those who had a bone marrow transplant.\n\nObjective:\n\nTo learn how long RBCs survive in the body in people with SCD and other blood disorders compared to those whose disease was cured with a bone marrow transplant.\n\nEligibility:\n\nPeople aged 18 years or older with SCD or another inherited blood disorder. People whose SCD or blood disorder was cured with a bone marrow transplant are also needed.\n\nDesign:\n\nParticipants will be screened. They will have a physical exam with blood and urine tests.\n\nParticipants will have about 7 tablespoons of blood drawn. In the lab, this blood will be mixed with a vitamin called biotin. Biotin sticks to the outside of RBCs. This process is called \"biotin labeling of RBCs.\" The next day, the participant s own biotin-labeled RBCs will be returned to their bloodstream.\n\nParticipants will return regularly to have smaller blood samples (about 2 teaspoons) drawn. These samples will be tested to detect the percentage of cells that have biotin labels. These visits may be every 2 weeks, 4 weeks, or some other interval. Participants will continue this schedule for up to 20 weeks or until biotin can no longer be detected....",[79,80,81],"Sickle Cell Disease","Thalassemia","Hemoglobinopathy",[83,81,80,79,84],"Red Cell","Biotin","2026-02-21",{"date":87,"type":88},"2026-02-24","ACTUAL",{"date":90,"type":88},"2024-05-17",{"date":92,"type":73},"2029-06-15",{"name":24,"class":6},1]
