National Heart, Lung, and Blood Institute (NHLBI)·interventional·Posted Feb 17, 2020·Updated Apr 27, 2025

In Brief

A Phase 2 clinical trial evaluating Eltrombopag for Anemia, Diamond-Blackfan. Completed, enrolled 15 participants across 1 site.

Detailed Summary

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....

Eltrombopag will be administered to participants 12 years of age an above will receive the adult dose of 150 mg by mouth daily. Participants between ages of 6 and 11 years old will start at 75 mg by mouth daily, and children 2 and 5 years of age will start at 2.5 mg/kg, not to exceed 75 mg by mouth daily. To adjust for the higher expected exposure in participants of East Asian and South East Asian ancestry, the starting dose for East Asian and South East Asian participants 12 years of age and above will be 75 mg by mouth once daily. For East Asian and South East Asian participants between 6 and 11 years of age, the starting dose will be 37.5 mg once daily by mouth, and for children between 2 and 5, the starting dose will be 1.25 mg/kg by mouth.
