Pilot Phase I/II Study of Amino Acid Leucine in Treatment of Patients With Transfusion-Dependent Diamond Blackfan Anemia
Recruiting
Trial ID: NCT01362595
Purpose
This study will determine the safety and possibility of giving the amino acid, leucine, in
patients with Diamond Blackfan anemia(DBA)who are on dependent on red blood cell
transfusions.
The leucine is expected to produce a response in patients with DBA to the point where red
blood cell production is increased. Red cell transfusions can then be less frequent or
possibly discontinued.
The investigators will study the side effects, if any, of giving leucine to DBA patients.
Leucine levels of leucine will be obtained at baseline and during the study.
The drug leucine will be provided in capsule form and taken 3 times a day for a total of 9
months.
