 Before you can start treatment on this study, you will have what are called screening tests. These tests will help the doctor decide if you are eligible to take part in the study. You will have a physical exam, routine blood tests between 4-6 tablespoons, and a bone marrow aspirate. To collect a bone marrow aspirate, an area of the hip or chest bone is numbed with anesthetic and a small amount of bone marrow is withdrawn through a large needle. Women who are able to have children must have a negative blood or urine pregnancy test.
