Before treatment starts, participants will have a complete physical exam, including blood (about 8 teaspoons) tests. A chest X-ray may be taken. CT scans may be taken if needed. A bone marrow sample will be taken through a large needle in the hipbone. Women able to have children must have a negative blood pregnancy test. An ECG (tracing of the heart) and a cardiac scan or echocardiogram may be taken to check the heart function.
