Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Diamond-Blackfan anemia (DBA) is treated with steroids. But some people cannot take steroids, or steroids don t work. Other patients must get blood transfusions regularly which are time consuming and can have significant side effects. The drug eltrombopag can increase red blood cells. Researchers want to see if it can help people with DBA and, if so, for how long. Objective: To study the safety and efficacy of eltrombopag in people with DBA who have not responded to steroids or could not take them. Eligibility: People ages 2 and older with DBA who did not respond to steroids or could not take them, or their disease has returned despite taking them Design: Participants will be screened with: Medical and medicine history Physical exam MRI: Participants will lie in a machine that takes pictures of the liver. Blood and urine tests Bone marrow biopsy: A thin needle will remove a marrow sample from the participant's hip bone. Electrocardiogram Participants will take eltrombopag pills once daily for 24 weeks. They will have blood taken every 2 weeks. Participants will have visits 6 months. At 6 months, they will repeat all the screening tests and also have: Quality-of-life questionnaire Neurodevelopmental test (for participants younger than 18 years) If participants blood cell counts improve, they may keep taking eltrombopag for up to 3 more years. If so, they will have blood taken every 4 weeks. They will visit NIH every 6 months and repeat the above tests. Participants will be monitored for up to 3 years after they stop taking eltrombopag. They will visit NIH 6 months after treatment ends. If participants blood counts go down after treatment ends, they may restart the drug....
