Before treatment starts, patients will have a physical exam, including blood tests and urine tests. Women who are able to have children must have a negative blood pregnancy test. Bone marrow samples will be taken. For bone marrow sampling, a large needle is placed in the hipbone after it has been numbed. The bone marrow is then withdrawn through the needle. Patients will have a chest x-ray, computed tomography (CT) scans, an EKG, and tests of lung function.
